In a first aspect, the present application provides a method for processing a message. For example, the method may include: a network device obtains dynamic information corresponding to a message, and the dynamic information represents a state corresponding to an application to which the message belongs. Then, the network device can According to the dynamic information, network resource information corresponding to the packet is determined, so that the network device can process the packet based on the determined network resource information.

The application can bring a better QoE to the user, thereby improving the use experience brought by the application to the user, and making the control of the application more precise.

The dynamic information may include the state value of the application. For example, the dynamic information may be at least one of the following information: the resolution level of the application, the video bit rate of the application, the remaining duration of the application's cached video, the application's cached video The remaining data amount of the video, the ratio of the remaining data amount of the application's cached video to the total cache space, or the ratio of the remaining duration of the application's cached video to the total video duration. Alternatively, the dynamic information may also include a state indication of the application, and the state indication of the application is used to instruct the network device to provide enhanced network resources for the application. For example, the dynamic information may be at least one of the following information: the application has The remaining duration of the cached video is in the normal state, the alarm state or other states, the remaining data volume of the application's cached video is in the normal state, the alarm state or other states, and the ratio of the remaining data volume of the application's cached video to the total cache space is in the normal state , alarm status, or other status, the ratio of the remaining duration of the application's cached video to the total video duration belongs to the normal status, alarm status, or other status. Alternatively, the dynamic information can also reflect the state related to the application, including but not limited to: the related parameters of the device related to the application or the state indication corresponding to the related parameters. For example, the dynamic information can be at least one of the following information: where the application is located The end-to-end delay from the user equipment where the application is located to the service device of the application, the end-to-end delay jitter from the user equipment where the application is located to the service device, or the end-to-end rate from the user equipment where the application is located to the service device; another example, dynamic information It may also be a state indication corresponding to any of the above information, for example, the end-to-end rate from the user equipment where the application is located to the service equipment belongs to a normal state, an alarm state, or other states.

Wherein, the network resource information includes but is not limited to one or more of the following: service quality level, forwarding path, bandwidth, network slice, wireless channel or wireless frequency. The service quality level may be, for example, a quality of service (English: Quality of Service, referred to as: QoS) level or a service level agreement (English: Service Level Agreement, referred to as: SLA) level. For example, if the network resource information includes a forwarding path, after the network device determines the network resource information, the network device can send a packet according to the forwarding path in the network resource information; for another example, if the network resource information includes network fragments, then , after the network device determines the network resource information, the network device can process the packet in the network segment in the network resource information.

In a possible implementation manner, the network device determines the network resource information corresponding to the packet according to the dynamic information, for example, it may include: the network device determines the network resource information according to the dynamic information and application conditions, wherein , the application condition may include application characteristic information and/or application requirement information, the application characteristic information is used to characterize the attributes of the application, and the application requirement information is used to characterize the requirement of the application on the network. When the network to which the network device belongs, or when the network device mainly transmits packets of the same type of application, the network device may determine the network resource information only according to the dynamic information of the application, or determine the network resource information according to the dynamic information of the application and the application requirement information . When the message transmitted by the network is related to multiple applications, the network device can determine the network resource information according to the dynamic information and application feature information, or can also determine the network resource information according to the dynamic information, application feature information and application requirement information. In this way, the network device that receives the message corresponding to the application can perceive the application condition and dynamic information of the application, and perform targeted processing of the message based on the application condition and dynamic information, so that the application can bring better benefits to the user. high QoE, so as to achieve more precise control of the application.

Then, the network device obtains the dynamic information corresponding to the packet, for example, the network device may parse the packet to obtain the dynamic information carried in the packet.

In another possible implementation manner, the dynamic information of the packet may be generated by a network device. For example, when the client and user equipment corresponding to the application do not have the ability to generate dynamic information, the above dynamic information may be generated by a network device. For example, the network device may be a broadband network gateway (English: Broadband Network Gateway, BNG for short) or a client-side device (English: Customer Premise Equipment, short: CPE) between the user equipment and the service device. Then, the network device obtains the dynamic information corresponding to the packet, for example, the network device may generate dynamic information corresponding to the packet according to the packet. The process of generating the dynamic information corresponding to the message by the network device according to the message may include: the network device performs flow-by-flow detection on the received message, and identifies the message that belongs to the same flow as the message, which may be specifically: The network device determines the flow to which the message belongs according to the application feature information carried in the message, and determines the messages in the flow; then, obtains the historical parameters of each message received in the flow, and based on the history The parameters generate dynamic information of the flow through technologies such as machine learning, artificial intelligence (English: Artificial Intelligence, AI for short) or deep packet inspection (English: Deep Packet Inspection, short for DPI). In this implementation manner, after acquiring the dynamic information corresponding to the packet, the network device may also update the packet, and the updated packet includes the acquired dynamic information.

In this way, each subsequent network device can obtain the corresponding network resource information from the updated message, so as to send the message based on the obtained network resource information, until the message is sent to the service device, without the need for each network The device determines the corresponding network resource information based on dynamic information, which saves network resources and improves traffic processing efficiency.

In a possible implementation manner, the network device may process the packet according to the network resource information corresponding to the dynamic information, for example, select the corresponding QoS level and forwarding path based on the dynamic information or network resource information in the packet or network resources such as network fragmentation, and process the packet according to the selected network resources.

In another possible implementation manner, the network device may also obtain a policy entry according to the network resource information corresponding to the dynamic information, so as to process the packet according to the policy entry. The network device obtaining the policy entry according to the network resource information corresponding to the dynamic information may, for example, be: the network device updates the policy entry according to the network resource information corresponding to the dynamic information, and obtains the updated policy entry. The policy entry may be a QoS level matching table, a forwarding table, a routing table, a tunnel table, a network fragment selection table, etc. locally set by the network device. The network device can use the query result to process the packet after querying the relevant entry according to the packet, such as processing the packet by using the QoS level, forwarding path or network fragment included in the query result.

The QoS related field is remarked, so that the network device in the next AS domain can accurately forward the second packet according to the value of the remarked QoS related field. On each network device in an AS domain, the packet can determine the corresponding QoS level, forwarding path and/or network fragment according to the value of the QoS-related fields, so as to use the determined QoS level, forwarding path and/or network Fragmentation processes the packet.

Detailed ways

During the running process of the application on the user equipment, the network device connected to the user equipment performs access control on the application used by the user on the user equipment, and provides corresponding network services for the user. However, at present, the control of the application running on the user equipment by the network equipment cannot bring better QoE to the user.

Through the research on the application running process, it is found that some indicators of the application on the user equipment during the running process will affect the QoE brought by the application to the user, thereby affecting the user's subjective perception of the quality and performance of the service provided by the application. For example, for live video and VOD applications, the remaining video duration in the client cache of the application on the user device or the amount of data remaining in the cache can affect whether a stuck event occurs, and the occurrence of a stuck event will bring users Poor QoE; for example, for applications such as battle games and cloud games, the end-to-end round-trip time (RTT) delay measured by the client of the application on the user device can determine whether an error occurs. Operation, the occurrence of misoperation will bring poor QoE to users.

Based on this, the present application provides a packet processing method. The packet processing considers parameters that affect the QoE brought by the application to the user (hereinafter referred to as dynamic information). For example, the method may include: the network device first obtains the Receive dynamic information corresponding to the message, the dynamic information representing the state corresponding to the application to which the message belongs; then, the network device determines the network resource information corresponding to the message according to the dynamic information, so that the network device can be based on the determined network resource information information to process the message. It can be seen that, through the method provided in this application, the network device that receives the message corresponding to the application can perceive the dynamic information of the application, and process the message in a targeted manner based on the dynamic information. The dynamic information enables the application to bring better QoE to the user, thereby improving the use experience brought by the application to the user, and making the control of the application more precise.

In order to facilitate the understanding of the present application, the meanings of some concepts involved in the present application are explained below.

The dynamic information representing the application-related state may include, but is not limited to: the relevant parameters of the device related to the application or the state indication corresponding to the relevant parameters. For example, the dynamic information may be at least one of the following information: the user equipment where the application is located to the application The end-to-end delay of the service device where the application is located, the end-to-end delay jitter from the user equipment where the application is located to the service device, or the end-to-end rate from the user equipment where the application is located to the service device; for example, the dynamic information can also be any of the above The state indication corresponding to the information, for example, the end-to-end rate from the user equipment where the application is located to the service equipment belongs to the normal state, the alarm state or other states.

The option value field in the Application-aware ID Option field shown in Figure 1, for example, can be shown in Figure 2a, including the APP ID field, the User ID field, the Flow ID field, and the SLA level; for example, it can be shown in Figure 2b, Including APP ID field, User ID field, Flow ID field, SLA level and other network performance parameter (English: Arguments) fields; another example can also be shown in Figure 2c, including Locator Address (English: Locator Address) field, function Identification (English: Function ID) field and Arguments field.

Application Requirement Information: Used to characterize the application's requirements for the network. The application requirement information may include but is not limited to: application requirements for network performance such as bandwidth, delay, delay jitter, and packet loss rate. As an example, the message corresponding to the application may carry the application requirement information through the application parameter information option (English: Service-para Option) field shown in FIG. 3 , wherein the Service-para Option field includes: Option Type field, Option Length field and Option Value field. The Option Type field is used to indicate that the option field is a Service-para Option field, that is, the value of the option value field in the option field is the application requirement information; the Option Length type is used to indicate the option field. The length of the Option Value field is the application requirement information.

If the packet corresponding to the application is a Segment Routing-Internet Protocol Version 6 (English: Segment Routing-Internet Protocol Version 6, abbreviated: SRv6) packet, then the application feature information and application requirement information can be carried in the packet in addition to In addition to the above-mentioned positions of the IPv6 packet header, it can also be carried in the segment routing header (English: Segment Routing Header, SRH) field of the SRv6 packet, specifically the SRH tag (English: Tag ) field, the SRH Type Length Value (English: Type Length Value, referred to as: TLV) field or the variable (English: Arguments, referred to as: Args) field of each segment identifier (English: Segment Identifier, referred to as: SID) in the SRH. The above manner of carrying the application feature information and application requirement information in the message is only exemplary, and this application does not specifically limit how to carry the application feature information and application requirement information of the application in the message corresponding to the application.

If the network resource information includes the service quality level and network fragmentation, the network device receiving the packet can determine the service quality level and network fragmentation of the packet according to the resource conditions of the packet, so as to enqueue the packet to the In the queue corresponding to the quality of service level, the packet is forwarded in the determined network segment. If the network resource information includes QoS level, forwarding path, bandwidth, network fragmentation, wireless channel and wireless frequency, the network device receiving the packet can determine the QoS level and forwarding path of the packet according to the resource conditions of the packet. , bandwidth, network fragmentation wireless channel and wireless frequency, so that the packet is queued into the queue corresponding to the quality of service level, and forwarded according to the determined forwarding path, bandwidth, network fragmentation, wireless channel and wireless frequency. Wherein, the service quality level includes but is not limited to the SLA level.

It should be noted that the various devices in this application are not specifically limited in this application.

In order to facilitate the understanding of the message processing method provided by the present application, the method will be described below with reference to the accompanying drawings.

FIG. 6 is a schematic flowchart of a packet processing method 100 provided by the present application. In order to introduce the present application more clearly, the method 100 is described in the way of interaction among user equipment, network equipment and service equipment, but the operations performed by each device in the method 100 may be used as a separate embodiment. Taking the structure of the network scenario shown in FIG. 5 as an example, the user equipment may be, for example, the user equipment 11 in FIG. 5 , the service device may be, for example, the service device 31 in FIG. 5 , and the network device may be, for example, the network device 21 in FIG. 5 . , network device 22 or network device 23 .

During specific implementation, the method 100 may, for example, include the following S101 to S106:

S101, a user equipment sends a first packet to a network device, where the first packet belongs to an application.

The first packet may be a packet generated by the user equipment and sent to the service device and corresponding to an application installed on the user equipment, and the destination address of the first packet matches the address of the service device corresponding to the application. The first message may be a data message or a control message. The fact that the first packet belongs to an application means that the first packet may be automatically generated by an application installed on the user equipment, or may be triggered and generated based on an operation performed by the user on the client corresponding to the application installed on the user equipment.

In specific implementation, the user equipment sends the first packet to the network device, and the network device may be any network device on the path that the packet on the user equipment goes to the service device, for example, the network shown in FIG. 5 may be used. Network device 21 in the scene.

S102, the network device acquires dynamic information corresponding to the first packet, where the dynamic information is used to represent the dynamic of the application.

The dynamic information corresponding to the first packet is used to represent the relevant status of the application to which the first packet belongs, including the status of the application and the status of the user equipment where the application is located. Dynamic information can be embodied in two forms: the status value of the application or the status indication of the application. The state value of the application may be a specific value of a relevant parameter during the running process of the application. For example, the dynamic information of the first packet may include the remaining duration of the cached video of the application; the state indication of the application may be determined according to the state value of the application Indication, used to indicate whether the network device that received the first packet needs to provide enhanced network resources for the application. For example, the dynamic information of the first packet may also include a status indication (normal or Alarm), the normal state can indicate that it is not necessary to provide enhanced network resources for the application, and the alarm state can indicate that enhanced network resources need to be provided for the application.

In a possible implementation manner, when the client or user equipment corresponding to the application has the ability to generate dynamic information, the dynamic information of the first packet may be generated by the user equipment and carried in the first packet, Then, in S102, for example, the network device may parse the first packet to obtain dynamic information carried in the first packet. If the client of the application communicates using the Transmission Control Protocol (English: Transmission Control Protocol, TCP), the first packet may be a data acquisition request message sent by the client of the application, or the first packet may also be the client of the application When an acknowledgment (English: ACK) message is sent after receiving the data, the first message may carry dynamic information. If the client of the application communicates using the User Datagram Protocol (English: User Datagram Protocol, UDP for short), the first packet may be a UDP data packet sent by the client of the application, or the first packet may be In the TCP data packet in the TCP communication corresponding to the UDP communication, the first packet may carry dynamic information.

It should be noted that, in this implementation manner, the first packet may consider that the dynamic information needs to be notified to the network device only when the dynamic information indicates that the application is in an abnormal state. Therefore, the dynamic information is carried in the first packet. However, when the dynamic information indicates that the application is in a normal state, it is considered that there is no need to inform the network device of the dynamic information, so the dynamic information is not carried in the first packet. Alternatively, the user equipment may also carry the dynamic information in the first packet when the dynamic information indicates that the application is in an abnormal state or a normal state.

During specific implementation, the first packet can carry the dynamic information through the Service Status Option (English: Service Status Option) field, and the Service Status Option field can be carried in the application-aware version 6 Internet Protocol network of the first packet. (English: Application-aware Internet Protocol version 6Networking, referred to as: APN6) option header. As shown in Figure 7a, the Service Status Option field may include: an Option Type field, an Option Length field, and an Option Value field. The Option Type field may be, for example, 1 byte, and the value of the Option Type field indicates that the type of the Option field is Service-Status Option; the Option Length field may be, for example, 1 byte, and the value of the Option Length field indicates that the Option The length occupied by the Value field; the length of the Option Value field is variable, and at least one sub-TLV field can carry at least one piece of dynamic information. For example, each sub-TLV field in the Option Value field carries one piece of dynamic information.

As shown in Figure 7b, each sub-TLV field in the Option Value field may include: Type field, sub-Type field, Length field, and Value field, where the Type field may be, for example, 2 bytes, which is used to indicate that the piece of dynamic information belongs to The sub-Type field can be, for example, 1 byte, which is used to indicate the subtype of the piece of dynamic information in the category to which it belongs, and together with the Type field to indicate the specific type of the piece of dynamic information; the Length field can be, for example, 1 byte, with Indicates the length of the Value field; the length of the Value field is variable and is used to carry the specific content of the piece of dynamic information. For example, the classification method for dynamic information includes but is not limited to: the value of the Type field can be 0x0000~0x001F, representing a general type, and the subtype represented by the value of the subType field can include: delay, jitter, bandwidth, etc., This general type can support 32*256=8192 specific types; the value of the Type field can be 0x0020 to 0x2020, representing an application type, such as a video application, and the subtypes represented by the value of the subType field can include: Cache duration, etc., the application type can support 8192 specific types; the value of the Type field can be 0x2021~0xEFFF: representing a specific application, such as the glory of the king, the subtype represented by the value of the subType field can include: The end-to-end delay, air interface delay, etc., this specific application can support 53215 specific types; the value of the Type field can be 0xF000~0xFFFF, representing the type of private application or experimental use, such as enterprise internal IT application, R&D system, sub-type The subtypes represented by the value of the field may include: delay, jitter, bandwidth, etc., and the private application or experimental use type may support 4096 specific types.

Alternatively, as shown in Figure 7c, each sub-TLV field in the Option Value field may also include: a Type field, a Length field, and a Value field, where the Type field may be, for example, 3 bytes, which is the same as the sub-TLV field shown in Figure 7b. Compared with the format, only the Type field and the Sub Type field in the sub-TLV field shown in FIG. 7b are combined into one Type field. Compared with the format of the sub-TLV field shown in Fig. 7b, the sub-TLV field shown in Fig. 7c may enable the network device to have better processing performance for the sub-TLV field.

For the sub-TLV field shown in FIG. 7b or FIG. 7c, the Value field carries the dynamic information corresponding to the first packet.

In one case, if the dynamic information is the status indication of the application, the format of the Value field may be shown in Figure 8a, for example, where the Value field may include: 1-bit E flag bit (indicating enhanced (English: Enhanced) ) or early warning (English: Early warning)) and a 31-bit reserved field. For example, when the E flag bit = 1, it can indicate that the application expects the network to provide it with better network services to avoid deterioration of the QoE of the application; when the E flag bit = 0, it can indicate that the application currently does not require network pairing its special treatment.

In another case, if the dynamic information is the state value of the application, the format of the Value field may be different according to the dynamic information. For example, for the dynamic information of video attributes, the format of the Value field can be as shown in Figure 8b, including: reserved field, resolution level (English: Resolution Level) and video bit rate (also called bit rate, English: Bitrate, Unit: Megabits per second (English: Mbps)). For another example, for the remaining duration of the buffered video, the format of the Value field may be as shown in Figure 8c, including: a reserved field and the remaining duration of the buffered video (English: Remaining Time of buffered Video), wherein the buffered video's The unit of the remaining duration is milliseconds (English: millisecond, abbreviated as: ms); for another example, for the remaining data amount of the cached video, the format of the Value field can be as shown in Figure 8d, including: the reserved field and the remaining data of the cached video Data volume (English: Remaining Size of buffered Video), wherein the unit of the remaining data volume of the cached video is kilobytes (English: kilobyte, abbreviation: KB); for another example, the remaining data volume of the cached video accounts for the cached video The percentage of the space, the format of the Value field can be as shown in Figure 8e, including: the reserved field and the percentage of the remaining data of the cached video in the cache space (English: Capacity Ratio). For another example, for the end-to-end delay from the user equipment to the service equipment, the format of the Value field may be as shown in Figure 8f, including: the reserved field and the end-to-end delay (English: End-to-End Delay, or It is called round trip time (English: Round Trip Time, abbreviation: RTT), unit: microsecond (English: microsecond, abbreviation: us)); for another example, for the end-to-end delay jitter from user equipment to service equipment, the Value field The format can be shown in Figure 8g, including: reserved field and end-to-end delay jitter (English: End-to-End Jitter, also known as RTT, unit: us); another example, for user equipment to service The end-to-end rate of the device, the format of the Value field can be shown in Figure 8h, including: T field, D field, reserved field and end-to-end rate (English: End-to-End Rate), where the T field is The value can represent the unit of the end-to-end rate. For example, 0 represents kilobits per second (English: Kbps), 1 represents Mbps, and 2 represents gigabits per second (English: Gbps). The value of the D field can represent the The end-to-end rate is the uplink rate or the downlink rate, such as: 0 for uplink and 1 for downlink.

In another possible implementation manner, the dynamic information of the first packet may be generated by a network device. For example, when the client and user equipment corresponding to the application do not have the ability to generate dynamic information, the above dynamic information may be generated by a device in the network. For example, the network device may be a broadband network gateway (English: Broadband Network Gateway, BNG for short) or a customer-side device (English: Customer Premise Equipment, short: CPE) between the user equipment and the service device. Then, S102 may include: the network device generates dynamic information corresponding to the first packet according to the first packet. The process of generating the dynamic information corresponding to the first packet by the network device according to the first packet may include: the network device performs flow-by-flow detection on the received packet, and identifies a packet belonging to the same flow as the first packet, Specifically, the network device may determine, according to the application feature information carried in the first packet, the flow to which the first packet belongs, and determine the packets in the flow; then, obtain the information of each packet received in the flow. Historical parameters, and based on the historical parameters through machine learning, artificial intelligence (English: Artificial Intelligence, referred to as: AI) or deep packet inspection (English: Deep Packet Inspection, referred to: DPI) and other technologies to generate the dynamic information of the flow.

It should be noted that, after receiving the first packet, the network device can obtain not only the dynamic information corresponding to the first packet, but also the application feature information used to characterize the corresponding packet. information and dynamic information, determine the processing method for the first packet, for example, determine the forwarding path 1 and forwarding path 2 corresponding to the application according to the application feature information, and determine the forwarding path 1 from the forwarding path 1 and the forwarding path 2 according to the dynamic information , and forward the first packet according to forwarding path 1. For example, the application feature information may be carried in the first packet. Alternatively, the network device can also obtain application requirement information that is used to characterize the network requirements of the application, and the network device can implement dynamic path calculation based on the application requirement information and the application feature information. The information and dynamic information determine how the first packet is processed.

S103: The network device determines network resource information corresponding to the first packet according to the dynamic information.

Optionally, the network device determines the foregoing network resource information according to dynamic information and application conditions. Wherein, the application condition includes application characteristic information and/or application requirement information.

In one case, the network device in S103 may determine the network resource information according to the dynamic information; in another case, the network device in S103 may determine the network resource information according to the dynamic information and the application feature information in the application conditions; In this case, the network device in S103 may determine the network resource information according to the dynamic information and the application feature information and application requirement information in the application conditions. Wherein, when the network to which the network device belongs, or when the network device mainly transmits packets of the same type of application, the network device may determine the network resource information only according to the dynamic information of the application, or determine the network according to the dynamic information of the application and the application requirement information. resource information. When the message transmitted by the network is related to multiple applications, the network device can determine the network resource information according to the dynamic information and application feature information, or can also determine the network resource information according to the dynamic information, application feature information and application requirement information.

The network resource information includes one or more of the following information: service quality level, forwarding path, bandwidth, network slice, wireless channel or wireless frequency. The service quality level may be, for example, a quality of service (English: Quality of Service, QoS for short) level or an SLA level.

In a possible implementation manner, if the dynamic information is the state value of the application, the network device may save the corresponding threshold, and S103 may specifically include: the network device determines the first report according to the comparison between the state value of the application and the threshold. Corresponding network resource information. The threshold can be a fixed value pre-configured statically or dynamically on the network device, or a variable value that is continuously adjusted and updated during the operation of the network device, or generated through technologies such as machine learning, big data, or AI.

As an example, the dynamic information includes the remaining duration of the cached video, and the network resource information includes the forwarding path as an example for description. It is assumed that the video application 1 uses the remaining duration of the buffered video as dynamic information, taking the format shown in FIG. 8c as an example. In the network shown in FIG. 9 , video application 1 runs on five user equipments, and the five user equipments belong to: users 1 to 5 respectively. The five user equipments are connected to network device A respectively, and the service of video application 1 The device is connected to network device B. Assuming that user 1 carries dynamic information, the remaining duration of the cached video is 1 second (English: second, abbreviated as: s); user 2 carries dynamic information, and the remaining duration of the cached video is 5s; user 3 carries dynamic information, The remaining duration of the cached video is 10s; user 4 carries dynamic information, and the remaining duration of the cached video is 30s; user 5 does not carry dynamic information.

For the single-threshold scenario, assuming that the network device uses 6s as the threshold, if the remaining duration of the cached video in the dynamic information of a traffic is less than 6s, switch to use path 1 (that is, the path from network device A to network device B through network device C) Transmit the traffic; if the remaining duration of the cached video in the dynamic information of a traffic is greater than or equal to 6s, or the packets in the traffic do not carry dynamic information, switch to use path 3 (that is, network device A passes through network device E, network Device F, the path from network device G to network device B) transmits the traffic. Then, the traffic sent by video application 1 on user 1 and user 2 is transmitted using path 1, and the traffic sent by video application 1 on user 3, user 4, and user 5 is transmitted using path 3.

For the dual-threshold scenario, in one case, the threshold can be used as a parameter for path delay switching. For example, the network device uses 6s and 12s as the threshold. For a traffic, when the remaining duration of the cached video in the dynamic information is less than 6s, Switch to use path 1; when the remaining duration of the cached video in the dynamic information is greater than 12s, switch to use path 2 (ie, the path from network device A to network device B through network device D). Assuming that user 1 carries dynamic information, the remaining duration of the cached video at T1 is 20s, the remaining duration of the cached video at T2 is 10s, the remaining duration of the cached video at T3 is 3s, and the remaining duration of the cached video at T4 is 8s , the remaining duration of the cached video at time T5 is 30s. Then, in the T1-T2 and T2-T3 periods, since the remaining duration of the cached video at T1 is greater than 20s, and the remaining duration of the cached video in the T1-T2 and T2-T3 periods is not less than 6s, path 2 is used. Transmit video application 1; at time T3, since the remaining duration of the cached video 3s is less than 6s, switch to path 1 to transmit video application 1; in the T3~T4 and T4~T5 periods, T1~T2 and T2 The remaining duration of the cached video in the ~T3 period is not greater than 12s, so use path 1 to transmit video application 1; at T5 time, since the remaining duration of the cached video 30s is greater than 12s, so switch to path 2 for video application 1 to transmit. In another case, the threshold can also be used as a parameter for the actual switching of the path. For example, the network device uses 6s and 12s as the threshold. For the traffic with the remaining duration of the cached video in the dynamic information less than 6s, use path 2 for transmission; for the traffic with the remaining duration of the cached video in the dynamic information greater than or equal to 6s and less than 12s, use path 4 (that is, network device A in turn It is transmitted through the path from network device H, network device I to network device B); for the traffic with the remaining duration of the cached video in the dynamic information greater than or equal to 12s or the traffic without dynamic information, use path 3 for transmission. Then, the traffic sent by video application 1 on user 1 and user 2 is transmitted using path 2, the traffic sent by video application 1 on user 3 is transmitted using path 4, and the traffic sent by video application 1 on user 4 and user 5 is transmitted using path 3 to transmit.

For a multi-threshold scenario, the threshold can also be used as a parameter for path delay switching or a parameter for actual path switching. Taking multiple thresholds as parameters for real-time switching of paths as an example, it is assumed that video application 1 uses the percentage of the remaining data of the cached video in the cache space (hereinafter referred to as the "proportion") as dynamic information, taking the format shown in Figure 8e as an example . Suppose user 1 carries dynamic information and the proportion is 3%; user 2 carries dynamic information and the proportion is 10%; user 3 carries dynamic information and the proportion is 30%; user 4 carries dynamic information and the proportion is 80%; User 5 does not carry dynamic information. If the network device uses 5%, 15%, 50%, and 90% as the thresholds, for the traffic that accounts for less than 5% of the dynamic information, use path 1 for transmission; for the proportion of dynamic information greater than or equal to 5% and For traffic less than 15%, use path 2 for transmission; for traffic that accounts for more than or equal to 15% and less than 50% of dynamic information, use path 5 (that is, the path from network device A to network device B through network device J) For transmission; for the traffic that accounts for more than or equal to 50% and less than 90% of the dynamic information, use path 4 for transmission; for the traffic that accounts for more than 90% of the dynamic information or the traffic that does not carry dynamic information, use the path 3 to transmit. Then, the traffic from video application 1 on user 1 is transmitted using route 1, the traffic from video application 1 on user 2 is transmitted using route 2, the traffic from video application 1 on user 3 is transmitted using route 5, and the traffic from user 4 on user 4 is transmitted using route 5. The traffic sent by video application 1 is transmitted using path 4, and the traffic sent by video application 1 on user 5 is transmitted using path 3.

In another possible implementation manner, if the dynamic information is the state indication of the application, then S103 may specifically include: the network device determines the network resource information corresponding to the first packet according to the state indication of the application.

As an example, it is assumed that application 1 is provided with forwarding services of two QoS levels in the network: best effort (English: Best Effort, BE for short) and expedited forwarding (English: Expedited Forwarding, EF for short). When the network device determines that the E flag bit in the acquired dynamic information is 1, the EF level is used for the packet 1, and the transmission is prioritized; when the network device determines that the E flag bit in the acquired dynamic information is 0 If the packet 2 or packet 3 does not carry dynamic information, the BE level is used for packet 2 and packet 3 for normal transmission. If there are traffic of application 1 and other traffic in the network, and application 1 contains three users: user 1, user 2 and user 3, assuming that the traffic sent by application 1 of user 1 carries dynamic information and the E flag is 1, The traffic sent by user 2's application 1 carries dynamic information and the E flag is 0, and the traffic sent by user 3's application 1 does not carry dynamic information. Then, the traffic of user 1's application 1 will use the EF level with priority. For traffic using the BE level, traffic from user 2's application 1, user 3's application 1, and other traffic are transmitted in the network.

As another example, the dynamic information includes the end-to-end delay, and the network resource information includes the BE high-bandwidth network slice A and the ultra-low-latency low-bandwidth network slice B as an example for description. For the delay-sensitive battle game 1, assuming that the battle game 1 uses the dynamic information shown in Figure 8a, if the end-to-end delay is greater than 100ms, the dynamic information is carried in the sent message and the E flag in the dynamic information is taken The value is 1; if the end-to-end delay is less than 80ms and greater than or equal to 50ms, the outgoing packet carries dynamic information and the E flag in the dynamic information is 0; when the end-to-end delay is less than 50ms, the The outgoing packets do not carry dynamic information. If the network device determines that the E flag bit in the dynamic information corresponding to the received packet 1 is 1, it uses network fragment B for transmission; if the network device determines that the E flag bit in the dynamic information corresponding to the received packet 2 is 0 or When the received packet 3 does not carry dynamic information, the network fragment A is used for transmission. Then, the battle game 1 includes three users: users 1 to 3, and the end-to-end delays of the three users are 35ms, 90ms, and 125ms, respectively. At this time, the situation that the dynamic information is carried in the packets 1 to 3 of the users 1 to 3 may be: the traffic sent by the battle game 1 on the user 1 does not carry the dynamic information, and the traffic sent by the battle game 1 on the user 2 carries the dynamic information and E The value of the flag bit is 0, the traffic sent by the game 1 on user 3 carries dynamic information and the value of the E flag is 1; the traffic processing of each user by the network device can be as follows: the network device sends the data to the game 1 on user 1. The traffic from user 2 is transmitted by network segment A, the traffic sent by the network device to the battle game 1 on user 2 is transmitted by network segment A, and the traffic sent by the network device to the battle game 1 on user 3 is transmitted by network segment B.

When the first packet corresponds to multiple pieces of dynamic information, and the multiple pieces of dynamic information respectively correspond to different types of network resource information on the network device, then the network device can determine the corresponding network resource information according to each piece of dynamic information, so that based on the The first packet is processed by the determined pieces of network resource information. Or, when the first packet corresponds to multiple pieces of dynamic information, but there are at least two pieces of dynamic information in the multiple pieces of dynamic information that correspond to the same type of network resource information on the network device, then the network device can Corresponding network resource information is determined, and one network resource information corresponding to the at least two pieces of dynamic information is determined according to a preset rule (eg, selecting a better processing method), and the first packet is processed based on the determined network resource information.

S104, the network device sends a second packet according to the network resource information, where the second packet belongs to the application.

As an example, if the first packet received by the network device includes dynamic information, in one case, the second packet may be the first packet, that is, S104 is that the network device sends the first packet according to the determined network resource information. a message. In this way, each subsequent network device can obtain dynamic information from the first packet, determine corresponding network resource information according to the dynamic information, and send the first packet based on the determined network resource information until the first packet is The message is sent to the service device. In another case, the second packet may be obtained by the network device updating the first packet, and the updated first packet (ie, the second packet) includes network resource information. In this way, each subsequent network device can obtain the corresponding network resource information from the second message, so as to send the second message based on the determined network resource information, until the second message is sent to the service device, There is no need to determine corresponding network resource information based on dynamic information on each network device, which saves network resources and improves traffic processing efficiency.

As another example, if the first packet received by the network device does not include dynamic information, and the network device generates dynamic information according to the first packet, then, in one case, the second packet may be that the network device updates the first packet. obtained from the message, the updated first message (ie, the second message) includes the generated dynamic information. In this way, each subsequent network device can obtain dynamic information from the second packet, determine corresponding network resource information according to the dynamic information, and send the second packet based on the determined network resource information until the second packet is The message is sent to the service device. In another case, the network device may also determine the network resource information according to the generated dynamic information, and the second packet may be obtained by the network device updating the first packet, and the updated first packet (ie the second packet) ) includes network resource information. It should be noted that, in order for the subsequent network device and the service device to properly process the received message, the updated first message (that is, the second message) may also include dynamic information. In this way, each subsequent network device can obtain the corresponding network resource information from the second message, so as to send the second message based on the determined network resource information, until the second message is sent to the service device, There is no need to determine corresponding network resource information based on dynamic information on each network device, which saves network resources and improves traffic processing efficiency. In another case, the network device may also determine whether the generated dynamic information representation is in an abnormal state, and if it is in an abnormal state, the second packet may be obtained by the network device by updating the first packet, and the updated The first packet (that is, the second packet) includes network resource information and/or dynamic information; if it is in a normal state, the second packet is the first packet, that is, the first packet is not processed, and the The received first packet is used as the second packet in S104 to perform corresponding processing.

Wherein, the network device sends the second packet according to the network resource information, and if the next hop of the network device is still a network device instead of a service device, S104 may be that the network device sends the second packet to the next-hop network device If the next hop of the network device is still the service device, S104 may be that the network device sends the second message to the service device.

In a possible implementation manner, the network device may process the second packet according to the network resource information corresponding to the dynamic information, for example, select the corresponding QoS level, Network resources such as forwarding paths or network fragments, and process the second packet according to the selected network resources.

In another possible implementation manner, the network device may also obtain a policy entry according to the network resource information corresponding to the dynamic information, so as to process the second packet according to the policy entry. The network device obtaining the policy entry according to the network resource information corresponding to the dynamic information may, for example, be: the network device updates the policy entry according to the network resource information corresponding to the dynamic information, and obtains the updated policy entry. The policy entry may be a QoS level matching table, a forwarding table, a routing table, a tunnel table, a network fragment selection table, etc. locally set by the network device. The network device may use the query result to process the second packet after querying the relevant entry according to the second packet, such as processing the second packet by using the QoS level, forwarding path or network fragment included in the query result.

In another possible implementation manner, if the network device is a boundary device of an autonomous system (English: Autonomous System, AS) domain for short, the network device may also be based on dynamic information or network resource information corresponding to the dynamic information , mark the QoS-related fields in the second packet. The QoS-related fields include but are not limited to: IPv6 Differentiated Services Code Point (English: Differentiated Services Code Point, DSCP for short) or flow type (English: Traffic Class, short for short) : TC) field, the fourth version of the Internet Protocol (English: Internet Protocol version 4, referred to as: IPv4) type of service (English: Type of Service, referred to as: ToS) field, Multiprotocol Label Switching (English: Multiprotocol Label Switching, referred to as: : MPLS) experimental purpose (English: Experimental Use, referred to as: EXP) field (also known as TC field), virtual local area network (English: Virtual Local Area Network, referred to as: VLAN) priority code point (English: Priority Code Point, Abbreviation: PCP) field, etc. The network device in the AS domain can process the second packet according to the QoS-related fields; however, when the second packet enters the next AS domain, the border device in the next AS domain needs to use the dynamic information or the corresponding dynamic information The network resource information re-marks the QoS-related field, so that the network device in the next AS domain can accurately forward the second packet according to the value of the re-marked QoS-related field. On each network device in an AS domain, the second packet can determine the corresponding QoS level, forwarding path and/or network fragment according to the value of the QoS-related field, so as to use the determined QoS level, forwarding path and/or The network fragment processes the second packet.

S105. The service device receives the second packet and generates a third packet, where the third packet includes the dynamic information.

Considering that the path through which the user equipment sends traffic to the service device and the path through which the service device sends traffic to the user equipment may be different, the dynamic information reflecting the state of the application on the client of the user equipment can also affect the service equipment to the user. The processing of the application traffic by the network device through which the device sends traffic. Therefore, when the service device receives the second packet including dynamic information, the service device can also send the user equipment to the application corresponding to the packet. Carrying the dynamic information, in this way, the network device through which the service device sends the message to the user equipment can also perceive the state of the application, so as to reasonably process the message of the application based on the dynamic information in the received message .

In the method 100, it is taken as an example that the message sent by the service device to the user equipment is the third message. The manner of carrying the dynamic information in the third message may refer to the formats shown in FIGS. 7a-7c and 8a-8h. I won't go into details here.

S106, the service device sends the third packet to the user equipment.

The service device may send the third packet to the user equipment via at least one network device. Wherein, each network device that the third packet passes through may process the third packet according to the dynamic information carried in the third packet. network resource information, so as to process the third packet according to the network resource information. For the processing of the third packet by each network device through which the third packet passes, reference may be made to the description of the manner in which the network device processes the first packet or the second packet in S103 and S104, which will not be repeated here.

In this way, the network device through which the message corresponding to the application passes can perceive the state of the application according to the dynamic information corresponding to the message, and provide different network services accordingly, and dynamically optimize the message of the application. For the traffic of one type, one type or all applications, the network can allocate multiple levels of network resources. Different levels of network resources correspond to, but are not limited to, different forwarding paths, different QoS levels, the radio channel and/or radio frequency, etc. Network devices can process and forward traffic using different levels of network resources based on dynamic information. For example, network resources can be divided into two levels: basic and enhanced. For the traffic of applications in the normal state, the network resources of the basic level are used for transmission; for the traffic of applications in the alarm state, the network resources of the enhanced level are used for transmission. Among them, for basic network resources, for example, the QoS level can be set to BE, and the forwarding path with the minimum number of hops can be set; for the enhanced network resources, for example, the QoS level can be set to EF, and the low-latency forwarding path or network sharding.

It should be noted that the user equipment, service equipment, and network equipment in the above method 100 may be collectively referred to as communication equipment. The operations performed when the communication equipment is a user equipment, the operations performed when the communication equipment is a network equipment, and the communication equipment are service equipment. The operations performed at the time can be independently implemented as separate embodiments, and the above description is only an interactive description for the purpose of clarifying and completing the description of the technical solution. For the user equipment, the dynamic information reflecting the current state of the application can be carried in the message sent to the service device, which provides a prerequisite for the subsequent network device to properly process the message. For network devices, dynamic information reflecting the application state can be sensed, and packets can be processed reasonably based on the dynamic information, so that the application can bring better QoE to users. For the service device, the dynamic information that reflects the application state can be carried in the message sent to the user device, so that the network device through which the message from the service device to the user device passes can perceive the current state of the application, so that the application can bring the application to the user. Better QoE is possible.

It can be seen that, through the method 100, the dynamic information that affects the QoE brought by the application to the user is considered in the processing of the packet, that is, the network device first obtains the dynamic information used to represent the state of the application to which the received packet belongs, and determines according to the dynamic information. The network resource information corresponding to the packet, so that the network device can process the packet based on the determined network resource information. It can be seen that the network device that receives the message corresponding to the application can perceive the dynamic information of the application and process the message in a targeted manner based on the dynamic information. The dynamic information of the application is considered in the message processing process so that the application can provide The user brings better QoE, which can improve the use experience brought by the application to the user, and make the control of the application more precise.
