Description

Data forwarding method and related device in optical fiber communication

This application claims the priority of a Chinese patent application filed with the State Intellectual Property Office of China, the application number is 202010165877.1, and the invention title is "A method and related device for data forwarding in optical fiber communication" on March 11, 2020, and its entire contents Incorporated in this application by reference.

Technical field

This application relates to the field of communication technology, and in particular to a data forwarding method and related devices in optical fiber communication.

Background technique

In order to ensure the quality of communication services in optical fiber communications, traffic classification technology needs to be used to classify traffic. For different types of traffic, according to their corresponding priority or service level characteristics, the traffic and traffic resources are controlled to provide different levels of services.

One method of traffic identification is to classify the traffic according to the PRI field in the virtual local area network (VLAN) frame header. The length of the PRI field is 3 bits, which can represent 8 priority levels, and the values are 7, 6, 5, 4, 3, 2, 1, and 0 in descending order of priority. According to the priority identification of each service, the corresponding level of service quality can be obtained, such as service delay, jitter, and available bandwidth.

Due to the increase in actual business types, one type of business may include multiple sub-types of business, and different sub-types of business have different requirements for service quality. The eight levels of service quality can no longer meet the actual business's demand for service quality.

Summary of the invention

In view of this, the present application provides a data forwarding method and related devices in optical fiber communication, which can create a network slice for a target service, and schedule service data through the network slice, so as to meet the service quality requirements of the target service.

The first aspect provides a data forwarding method in optical fiber communication. In this method, a slice of a target service is created, and the target service is a virtual reality service or a high-definition video live broadcast service; a downlink message sent by a broadband network gateway is received; When one or more of the five-tuple information of the downlink message is found in the information table, the downlink message is added to the slice of the target service; after obtaining the downlink message from the slice of the target service, the downlink message is sent to the optical Network terminal. Among them, slicing is also called network slicing. The high-definition video live broadcast service is a live video service with a resolution greater than 2K, such as a 4K live broadcast service or an 8K live broadcast service or higher resolution live broadcast service. The 4K resolution adopted by the 4K live broadcast service is 4K resolution, which means that the pixel value of each row in the horizontal direction reaches or is close to 4096.

In this way, a network slice can be created for the target business, and the data of the target business can be scheduled through the network slice, so as to meet the service quality requirements of the target business. The above method can create network slices for virtual reality services, network slices for high-definition video live broadcast services, and network slices for two services, and then use the two network slices to forward virtual reality service packets or high-definition video live broadcast services. Message. The order in which the network slices of the two services are created is not limited, and they can be created one after the other or at the same time.

In a possible implementation of the first aspect, the above data forwarding method further includes: receiving an uplink packet sent by an optical network terminal before creating a slice of the target service; when five of the uplink packets are found in the preset information table. When one or more of the tuple information is used, a slice of the target business is created. This provides a way to create a network slice of the target service. In addition, network slices can be pre-created for the target service without the need for uplink messages.

In another possible implementation of the first aspect, adding the message to the slice of the target service includes: determining the target queue corresponding to the priority of the message; adding the message to the target queue; and obtaining the message from the slice of the target service. The text includes: getting a message from the target queue. The slice of the target service includes multiple queues, and each queue corresponds to a priority one-to-one. The number of queues included in the target service slice is not limited. When the target service slice includes 8 queues and the priority identifier is also 8, the message can be added to the corresponding queue according to the priority.

In another possible implementation of the first aspect, the data forwarding method further includes: when one or more of the five-tuple information of the downlink message is not found in the preset information table, indicating that the downlink message If it does not belong to the target service, add the downlink message to the slice of the non-target service; obtain the downlink message from the slice of the non-target service; and send the downlink message to the optical network terminal. Non-target business refers to business other than the target business. In one implementation, non-target services can be scheduled in a network slice according to priority.

In another possible implementation manner of the first aspect, the scheduling priority of the slice of the target service is higher than the scheduling priority of the slice of the non-target service. In this way, the target business can be prioritized to meet the service quality requirements of the target business. In the case where there are network slicing of the virtual reality service or the network slicing of the high-definition video live broadcast service at the same time, the scheduling priority of the network slicing of the virtual reality service may be higher than, equal to, or lower than the network slicing of the high-definition video live broadcast service.

Detailed ways

The data forwarding method of this application can be applied to an optical fiber communication system. Figure 1 is a schematic diagram of an optical fiber communication system. Referring to Fig. 1, the optical fiber communication system may include a user terminal 101, an optical network terminal (optical network terminal, ONT) 20, an optical line terminal (OLT) 30, a broadband network gateway (broadband network gateway, BNG) 40, and services. Server 50 etc.

In the upstream direction, the user terminal 10 sends information, such as service information or user information, to the ONT 20. The ONT 20 sends the above information to the OLT 30, and the OLT 30 classifies the above information according to service types, and then sends the above information to various service servers 50 through the BNG 40. The service server 50 may provide one or more services, such as a video service, an audio service, a real-time communication service, and a batch transmission service. In the downstream direction, after the OLT 30 aggregates various service data, the service data is dispatched and sent to the ONT 20, and the ONT 20 will send it to the user terminal 10.

In addition to converging and forwarding service data, the OLT can also implement device-based network element management and service-based security management and configuration management. Not only can it monitor and manage devices and ports, but it can also perform service activation and user status monitoring, and it can also allocate bandwidth according to the quality of service (QoS) or service level agreement (SLA) requirements of different users , As well as management and ranging of the ONT. In addition to OLT30 for bandwidth control, BNG40 can also be used for bandwidth control. The user terminal 10 may also be referred to as a terminal device, terminal, user equipment, electronic device, and so on. The user terminal 10 may specifically be a digital TV, a personal computer, a mobile phone, a tablet computer, a virtual reality (VR) device, and the like.

In the data forwarding process of the above-mentioned optical fiber communication system, there are currently a variety of simple traffic classification methods. One method classifies traffic according to the PRI field in the 802.1p domain of the virtual local area network (VLAN) frame header. The length of the PRI field is 3 bits (bit), which can indicate a total of 8 priority levels. The values are 7, 6, 5, 4, 3, 2, 1, and 0 in the order of priority, with different priorities Identifies different levels of service quality requirements. When each service is mapped to the corresponding priority queue, the service can obtain the corresponding delay, jitter and available bandwidth. In the above traffic classification method, the correspondence between the service type and the Ethernet priority can be as shown in Table 1:

Table 1

Another method of traffic classification is to classify traffic according to the type of service (Tos) field of the IP message. The Tos field includes 3 bits and can only represent 8 priority levels, so that only 8 types of services can be distinguished. Another method of traffic classification is to classify the traffic based on the TC value of the IPv6 packet. Another method of traffic classification is to classify traffic based on the EXP domain value of a multi-protocol label switching (multiprotocol label switching, MPLS) message. All of the above traffic classification methods can only distinguish limited types of business traffic.

Taking video services as an example, video services include sub-categories such as VR services, high-definition video live broadcast services, and interactive Internet TV (IPTV) services. Compared with IPTV services, VR services require lower latency. According to the above method, the VR service flow and the IPTV service flow are scheduled together. At this time, only the IPTV service quality requirement is met, and it is difficult to meet the service quality requirement of the VR service (for example, the delay requirement). In the same way, scheduling high-definition video live service traffic and IPTV service traffic together will also be difficult to meet the delay requirements of the high-definition video live service.

In order to meet the service quality requirements of VR services or HD video live broadcast services in optical fiber communication, this application classifies traffic according to IP quintuples, and then creates network slices for VR services or HD video live broadcast services, and uses network slices to schedule VR services Or high-definition video live broadcast service traffic to meet its service quality requirements. The method for data forwarding performed by an optical line terminal is described in detail below. Referring to FIG. 2, an embodiment of the data forwarding method in this application includes:

Step 201: Create a slice of the target service, where the target service is a virtual reality service or a high-definition video live broadcast service.

In this embodiment, slices are also called network slices. Network slicing can provide an end-to-end virtual network, including not only the network, but also computing and storage functions. Network slicing can not only achieve service isolation, but also isolate the services of different users. You can create network slices for virtual reality services, you can also create network slices for high-definition video live broadcast services, and you can also create network slices for two services separately. The order in which the network slices of the two services are created is not limited, and they can be created one after the other or at the same time.

Step 202: Receive a downlink message sent by the broadband network gateway.

The broadband network gateway can receive the downlink message sent by the service server, and then send the downlink message to the optical line terminal.

Step 203: When one or more of the quintuple information of the downlink message is found in the preset information table, the downlink message is added to the slice of the target service.

The quintuple information includes: source IP address, source port number, destination IP address, destination port number, and protocol identifier. For example, the preset information table stores the server IP address of the target service, and when the source IP address of the downlink message is the server IP address of the target service, it is determined that the downlink message belongs to the target service message. In another example, the preset information table stores the IP address of the user terminal. When the destination IP address of the downlink message is the IP address of the aforementioned user terminal, it is determined that the downlink message belongs to the target service message. In another example, the preset information table stores a protocol identifier corresponding to the target service. When the downlink message carries the protocol identifier, it is determined that the downlink message belongs to the target service message. In another example, the preset information table stores the source port number corresponding to the target service. When the source port number of the downlink message is consistent with the source port number stored in the preset information table, it indicates that the downlink message belongs to the message of the target service. In another example, the preset information table stores the destination port number corresponding to the target object. When the destination port number of the downlink message is consistent with the destination port number stored in the preset information table, it indicates that the downlink message belongs to the message of the target service.

The above describes the method for judging whether the downlink message belongs to the target service message according to one item in the quintuple information. This application can also judge whether the downlink message belongs to the target service message according to multiple items in the quintuple information. The information contained in the preset information table can be set according to actual judgment conditions, which is not limited in this application.

Step 204: Obtain a downlink message from the slice of the target service.

Step 205: Send the downlink message to the optical network terminal.

In this embodiment, a network slice is created for the target service, so that the target service is separated from the non-target service. The data of the target service is scheduled through network slicing, so that when non-target services are scheduled, the transmission of the target service will not be affected, thereby meeting the service quality requirements of the target service.

Secondly, through the slicing of the target business, it is also possible to isolate the same business of different users, so as to better guarantee the service quality of the business.

In an alternative embodiment,

The above data forwarding method further includes: receiving an uplink message sent by an optical network terminal;

Creating a slice of the target service includes: creating a slice of the target service when one or more of the quintuple information of the uplink message is found in the preset information table.

In this embodiment, the uplink message may be a service request or service data. When one or more of the five-tuple information of the uplink message is found in the preset information table, it means that the uplink message belongs to the message of the target service. At this time, a slice of the target service is created to facilitate the transmission of the target service. Subsequent messages.

For example, the preset information table stores the address of the server IP of the target service. When the destination IP address of the uplink message is the address of the server IP of the target service, it is determined that the uplink message belongs to the message of the target service. In another example, the preset information table stores the IP address of the user terminal. When the source IP address of the uplink message is the IP address of the user terminal, it is determined that the uplink message belongs to the message of the target service. In another example, the preset information table stores a protocol identifier corresponding to the target service. When the uplink message carries the protocol identifier, it is determined that the uplink message belongs to the message of the target service. In another example, the preset information table stores the source port number corresponding to the target service. When the upstream message carries the source port number, it is determined that the upstream message belongs to the message of the target service. In another example, the preset information table stores the destination port number corresponding to the target service. When the uplink message carries the destination port number, it is determined that the uplink message belongs to the message of the target service.

This provides a feasible method for creating a slice of the target service based on the quintuple information of the uplink message. In addition, the optical line terminal can pre-create network slices for the target service without the need for uplink messages.

In another alternative embodiment,

Adding the downlink message to the target service slice includes: determining the target queue corresponding to the priority of the downlink message; adding the downlink message to the target queue;

Obtaining the message from the slice of the target service includes: obtaining the downlink message from the target queue.

In this embodiment, the slice of the target service includes multiple queues, and each queue corresponds to a priority one-to-one.

For example, when the target service slice includes 8 queues and the priority identifier is also 8, the message can be added to the queue according to the priority. Specifically, a VR service may include multiple sub-category services, and the service quality requirements of each sub-category service are different from those of other sub-category services. In this way, its sub-category services can be scheduled through 8 priority levels to meet the service quality requirements of its sub-category services. For the queues in the network slicing of the high-definition video live broadcast service, the methods for setting the queue, adding to the queue, and exiting the queue can refer to the relevant description of the VR service slicing, which will not be repeated here.

In another optional embodiment, the slice of the target service includes a queue. The packets of the target service are scheduled through a queue.

In another optional embodiment, the slice of the target service includes multiple queues, and each queue corresponds to multiple priorities. For example, when the target service slice includes 4 queues and priority identifiers are 8, the priority identifiers can be divided into 4 groups, for example, the first group includes priority 0 and priority 1, and the second group includes priority 2 and Priority 3, the third group includes priority 4 and priority 5, and the second group includes priority 6 and priority 7, so that a group of priority packets are added to a queue. The priority included in each group can also be set in other ways, which is not limited in this application.

In another example, after creating a slice of the target service, the above data forwarding method further includes: receiving an uplink message sent by an optical network terminal; when the quintuple information of the uplink message is found in the preset information table, The uplink message is added to the slice of the target service, the uplink message is obtained from the slice, and the uplink message is sent to the broadband network gateway. In this way, the uplink message can be transmitted through the slice of the target service. In another example, the uplink message may not be forwarded through the slice of the target service, but is directly sent by the optical line terminal to the broadband network gateway.

In another optional embodiment, the foregoing data forwarding method further includes: when one or more of the five-tuple information of the downlink message is not found in the preset information table, adding the downlink message to the non-target service Slicing; Obtain the downlink message from the slice of the non-target service; Send the downlink message to the optical network terminal.

In this embodiment, non-target services refer to services other than the target services. When one or more of the quintuple information of the downlink message is not found in the preset information table, it means that the downlink message does not belong to the target service, so the downlink message is added to the slice of the non-target service. Specifically, the downlink message can be added to the corresponding queue in the slice of the non-target service according to the priority. In this way, the target service and the non-target service are scheduled through different slices, which can ensure the independence of scheduling, so as to meet the service quality requirements of different services.

In another optional embodiment, the scheduling priority of the slice of the target service is higher than the scheduling priority of the slice of the non-target service. In this way, the target business can be prioritized to meet the service quality requirements of the target business.

In the case where there are network slicing of the virtual reality service or the network slicing of the high-definition video live broadcast service at the same time, the scheduling priority of the network slicing of the virtual reality service may be higher than, equal to, or lower than the network slicing of the high-definition video live broadcast service.

For ease of understanding, the following describes the data forwarding method of this application with a business processing process. Referring to FIG. 3, an embodiment of the data forwarding method in this application includes:

Step 301: The user terminal sends the virtual reality service request to the optical network terminal.

Step 302: The optical line terminal receives the virtual reality service request sent by the optical network terminal.

Step 303: When the destination IP address carried in the virtual reality service request is found in the preset information table, the optical line terminal creates a slice of the virtual reality service.

Step 304: The optical line terminal sends the virtual reality service request to the broadband network gateway.

Step 305: The broadband network gateway forwards the virtual reality service request to the service server. The service server can handle virtual reality services.

Step 306: The service server obtains virtual reality service data according to the virtual reality service request.

Step 307: The service server sends the virtual reality service data to the broadband network gateway.

Step 308: The broadband network gateway sends the virtual reality service data to the optical line terminal.

Step 309: When the source IP address of the virtual reality service data is found in the preset information table, the optical line terminal adds the virtual reality service data to the slice of the virtual reality service.

Step 310: The optical line terminal obtains virtual reality service data from the slice of the virtual reality service.

Step 311: The optical line terminal sends the virtual reality service data to the optical network terminal.

Step 312: The optical network terminal sends the virtual reality service data to the user terminal.

This method can effectively guarantee the service quality requirements of virtual reality services through network slicing. Among them, the virtual reality service request, the virtual reality service data, the source IP address, the destination IP address, etc. are all illustrative examples, and are not intended to limit the application.
