Detailed ways

In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

It should be noted that, although the functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first", "second", etc. in the specification, claims and the above drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

In the embodiments of the present application, the words "further", "exemplarily" or "optionally" are used to indicate examples, illustrations or descriptions, and should not be interpreted as being more preferred or more advantageous than other embodiments or designs. The use of the words "further", "exemplarily" or "optionally" is intended to present related concepts in a specific way.

At present, information networks are transforming from network infrastructure centered on information transmission to intelligent cloud network infrastructure integrating computing, storage, and transmission resources. Computing network is a good practice and application of cloud-network integration. In the process of cloud migration, it is necessary to consider network factors (such as latency, bandwidth, packet loss rate, etc.) and computing power factors (such as cost, etc.). Comprehensively select computing resource pools that meet the requirements to meet the requirements of various new applications and vertical industries.

The computing power network provides computing power service points, which may have multiple instances and can be located in different cloud resource pools, including one or more network nodes in the end domain, one or more network nodes in the network domain, and one or more network nodes in the cloud domain. For example, if a terminal user wants to access a service, it is necessary to comprehensively consider network factors and computing power factors to allocate and select computing power resource pools. The selection of service instances in such computing power resource pools cannot be completed through a single IP routing, and it is necessary to address and select service instances based on service + routing.

The computing power ID is an abstract expression of the service in the cloud pool, representing the capabilities and requirements of the computing power service. In the network domain, the computing power resource pool needs to be selected based on the computing power ID. Therefore, the message encapsulation and forwarding of the computing power ID is the key technology for network devices to implement computing power resource pool selection.

In related technologies, computing power identification is an abstract expression of services in a cloud pool, representing the capabilities and requirements of computing power services, and is a key technology for network devices to select computing power resource pools. Regarding the encapsulation of computing power identification in the sixth-generation Internet Protocol IPV6 message, there are multiple extension headers in the existing IPV6 system for IPV6 extension, but these extension headers have certain encapsulation defects, resulting in fixed and limited application scenarios, which cannot meet the requirements of computing power network service forwarding.

For example, for the Destination Option Header (DOH), DOH encapsulation requires TLV parsing and encapsulation when the message reaches the destination address, but the computing power gateway may have multiple nodes that need to be processed. For example, there may be a secondary gateway processing node in the network domain, and the computing power identifier may also need to be extracted for processing in the cloud domain. Therefore, a single destination node processing TLV cannot meet the computing business requirements. TLV, namely Type-Length-Value, is an optional encoding format in the data communication protocol. Type represents the type of the entire data block, which can be represented by a digital code. Length is a fixed length, generally 1-4 bytes, and Value represents a variable-length byte set.

For example, for the Hop-By-Hop option (HBH), each hop node is required to process it, while the intermediate node of the gateway may not need to process it. In this case, devices that do not support this type of HBH may discard the message and cannot meet the computing power network service forwarding requirements well.

For example, for the Segment Routing Head (SRH), it is necessary to arrange the routing table in advance, determine which nodes need to process the computing power identifier, and arrange these nodes in advance, which limits the application scenarios.

Based on this, the present application provides a service processing method, communication equipment, storage medium and program product. The service processing method of one embodiment includes: when it is determined that the destination address of the received service message carries the target computing power SID (Segment ID), the computing power service addressing is performed according to the preset forwarding rule of the target computing power SID. In this embodiment, when it is determined that the destination address of the received service message carries the target computing power SID, the computing power service addressing is performed according to the preset forwarding rule of the target computing power SID, so that the corresponding computing power network service can be processed at the required network node based on the preset forwarding rule of the target computing power SID, which overcomes the impact of encapsulation defects in related technologies, is conducive to expanding the application scenarios of computing power network services, and can meet the requirements of computing power network service forwarding.

The embodiments of the present application are further described below in conjunction with the accompanying drawings.

As shown in FIG. 1 , FIG. 1 is a schematic diagram of a computing network for executing a business processing method provided in one embodiment of the present application.

In the example of FIG1 , the computing power network provides a computing power service point, which has multiple instances and can be located in different cloud resource pools. For example, the computing power network shown in FIG1 includes a network node (i.e., a terminal node) in the end domain, two network nodes (i.e., a first gateway node and a second gateway node) in the network domain, and multiple cloud nodes in the cloud domain, etc., wherein: The network domain includes at least two network nodes, wherein the first gateway node communicates with the end domain as an entry gateway node, and the second gateway node communicates with the cloud domain as an exit gateway node. The cloud node may include, but is not limited to, a load balancing layer (Loader Balancer, LB) and a server connected to the LB, and the LB is used to connect to the second gateway node to receive the forwarded service message. It should be noted that the number of network nodes in the network domain may also be, but is not limited to, more than two. That is to say, while ensuring the existence of population gateway nodes and exit gateway nodes, the network domain can also provide routing services for more network nodes, which is not limited here.

The technical solutions of the embodiments of the present application can be applied to various communication systems, for example: wideband code division multiple access mobile communication system (WCDMA), evolved universal terrestrial radio access network (EUTRAN) system, next generation radio access network (NGRAN) system, long term evolution (LTE) system, worldwide interoperability for microwave access (WiMAX) communication system, fifth generation (5G) system, such as new generation radio access technology (NR), and future communication systems, such as 6G system.

Each network node of the embodiment of the present application can be an entity or terminal device for receiving or transmitting signals, such as a mobile phone. The terminal device can also be called a terminal device (terminal), a user equipment (UE), a mobile station (MS), a mobile terminal device (MT), etc. The terminal device can be a car with communication function, a smart car, a mobile phone (mobile phone), a wearable device, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in a smart city (smart city), a wireless terminal device in a smart home (smart home), etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the terminal.

Those skilled in the art will appreciate that the implementation environment shown in FIG. 1 does not constitute a limitation on the embodiments of the present application, and may include more or fewer components than shown in the figure, or a combination of certain components, or a different arrangement of components.

Based on the computing power network shown in FIG1 above, various embodiments of the business processing method of the present application are proposed below.

As shown in Figure 2, Figure 2 is a flow chart of a service processing method provided by an embodiment of the present application, and the service processing method can be, but is not limited to, applied to the first gateway node in the computing network shown in Figure 1. The service processing method can include, but is not limited to, step S1000.

Step S1000: When it is determined that the destination address of the received service message carries the target computing power SID, computing power service addressing is performed according to the preset forwarding rule of the target computing power SID.

In this step, when it is determined that the destination address of the received service message carries the target computing power SID, computing power service addressing is performed according to the preset forwarding rules of the target computing power SID, so that the corresponding computing power network service can be processed at the required network node based on the preset forwarding rules of the target computing power SID. This overcomes the impact of encapsulation defects in related technologies, is conducive to expanding the application scenarios of computing power network services, and can meet the requirements of computing power network service forwarding.

In one embodiment, the preset forwarding rules of the target computing power SID may be multiple, which are not limited here. For example, the preset forwarding rules of the target computing power SID may be predefined and have a one-to-one correspondence, that is, each computing power SID Corresponding preset forwarding rules can be set for it. When it is necessary to address the computing power service through it, the corresponding preset forwarding rules can be called to address the computing power service.

In one embodiment, when the preset extension header of the service message carries a computing power identifier, computing power service addressing is performed according to the preset forwarding rule of the target computing power SID, so that the computing power identifier is extracted from the preset extension header of the service message in the subsequent steps, and computing power routing addressing is performed based on the computing power identifier on the basis of the preset forwarding rule of the target computing power SID, that is, the computing power identifier is used as a form of expression of the computing power service in the computing power network. When it is confirmed that the preset extension header of the service message carries the computing power identifier, it means that the computing power network service forwarding can be performed specifically according to the computing power identifier to meet the requirements of computing power network service forwarding.

In one embodiment, determining whether the destination address of a received service message carries a target computing power SID can be achieved by judging whether the computing power type of a computing power SID is a preset computing power type. For example, when a service message carrying a computing power SID is received, the computing power SID is judged. If it is determined that the computing power type of the computing power SID is the preset computing power type, the computing power SID is judged to be the target computing power SID, and computing power service addressing can be performed according to the preset forwarding rules. Otherwise, it can be determined that the computing power SID is not the target computing power SID.

In one embodiment, the computing power type of the target computing power SID can be but is not limited to being configured as an endpoint compute (endpoint.compute, end.c) type. The end.c type is a predefined computing power type in IPV6 and is bound to a preset forwarding rule. That is, it is only necessary to determine whether a computing power SID is of the end.c type to determine whether a computing power SID is the target computing power SID.

It should be noted that the computing power type of the target computing power SID can also be selected and set according to the specific application scenario. For example, it can be set to more than one. Then, as long as the computing power type of a computing power SID meets at least one of the preset computing power types, the computing power SID can be judged as the target computing power SID. This is not limited here.

In one embodiment, the preset extension header includes: DOH or HBH. Alternatively, those skilled in the art may also select a corresponding preset extension header for setting according to a specific application scenario, which is not limited here.

The following specific examples are given to illustrate the working principles of the above-mentioned related embodiments, and are not intended to further limit the embodiments of the present application.

Example 1:

As shown in FIG. 3 , FIG. 3 is a schematic diagram of the encapsulation structure of a service message provided in an embodiment of the present application.

Referring to Figure 3, the encapsulation part of the business message includes the IPV6Header part and the DOH/HBH part, wherein the Destnation Address (i.e., the destination address) is encapsulated in the IPV6Header, and the DOH/HBH part indicates that it can be DOH or HBH; when it is detected that the Service ID (i.e., the computing power identifier) is encapsulated in the DOH/HBH, and it is determined that the Destnation Address is the preset end.c type, the computing power service addressing is performed according to the preset forwarding rules.

In one embodiment, the preset forwarding rules of the target computing power SID include, but are not limited to: parsing a preset extension header from a service message to obtain a computing power identifier; querying a computing power route according to the computing power identifier to determine a second gateway node of the computing power route; determining a next hop address of the computing power route according to the computing power route; and replacing the target computing power SID with the first SID of the second gateway node.

Among them, the preset extension header is parsed from the business message to obtain the computing power identifier, so as to further query the computing power route based on the computing power identifier; the computing power route is queried according to the computing power identifier to determine the second gateway node of the computing power route, that is, the exit gateway corresponding to the computing power route can be determined, so as to forward the business to the exit gateway; the next hop address of the computing power route is determined according to the computing power route, so as to forward the business message based on the next hop address; the target computing power SID is replaced with the first SID of the second gateway node to meet the requirements of computing power network business forwarding.

It should be noted that the preset forwarding rules of the target computing power SID in the above-mentioned embodiment are not limited to this. The preset forwarding rules of the target computing power SID can also be changed by mutual combination, splitting, etc., which is also within the protection scope of the embodiments of the present application and is not limited here.

As shown in FIG. 4 , an embodiment of the present application further illustrates step S1000 , which includes but is not limited to step S1100 .

Step S1100: Send a service message to the second gateway node according to the next hop address of the computing power routing, so that the second gateway node performs computing power service addressing according to the preset forwarding rule of the target computing power SID when determining that the destination address of the service message carries the first SID, wherein the computing power type of the first SID is the same as that of the target computing power SID.

In this step, when the next hop address is determined based on the preset forwarding rule, the service message is sent to the second gateway node according to the next hop address of the computing power routing to realize computing power service addressing, and by sending the service message to the second gateway node, when the second gateway node determines that the destination address of the service message carries the first SID, since the first SID and the target computing power SID have the same computing power type, that is, the preset forwarding rule of the target computing power SID can be used to forward the first SID, it is convenient for the second gateway node to perform computing power service addressing according to the preset forwarding rule of the target computing power SID.

In one embodiment, the computing power type of the first SID may also be configured as, but not limited to, end.c type.

As shown in Figure 5, Figure 5 is a flowchart of a business processing method provided by another embodiment of the present application, and the business processing method can be, but is not limited to, applied to a terminal node in the computing network shown in Figure 1. The business processing method can include, but is not limited to, step S2000.

Step S2000: Send a service message to the first gateway node, so that the first gateway node performs computing power service addressing according to the preset forwarding rules of the target computing power SID when determining that the destination address of the service message carries the target computing power SID.

In this step, the terminal node sends a service message to the first gateway node, so that the first gateway node performs computing power service addressing according to the preset forwarding rules of the target computing power SID when determining that the destination address of the service message carries the target computing power SID, so that the first gateway node can process the corresponding computing power network service at the required network node based on the preset forwarding rules of the target computing power SID. This overcomes the impact of encapsulation defects in related technologies, is conducive to expanding the application scenarios of computing power network services, and can meet the requirements of computing power network service forwarding.

In one embodiment, the first gateway node determines whether the destination address of the received service message carries the target computing power SID. This can be achieved by judging whether the computing power type of a computing power SID is a preset computing power type. For example, when a service message carrying a computing power SID is received, the computing power SID is judged. If it is determined that the computing power type of the computing power SID is the preset computing power type, the computing power SID is judged to be the target computing power SID. The computing power service addressing can be performed according to the preset forwarding rules. Otherwise, it can be determined that the computing power SID is not the target computing power SID.

As shown in FIG. 6 , in one embodiment of the present application, step S2000 also includes but is not limited to step S3000 .

Step S3000: Encapsulate the target computing power SID in the destination address of the business message, and encapsulate the computing power identifier in the preset extension header of the business message.

In this step, the terminal node pre-encapsulates the target computing power SID in the destination address of the business message and the computing power identifier in the preset extension header of the business message to achieve the encapsulation of the destination address and the preset extension header of the business message, so as to facilitate the first gateway node to further confirm the encapsulation of the destination address and the preset extension header of the business message in subsequent steps.

In one embodiment, the computing power type of the target computing power SID is configured as the end.c type.

It should be noted that since steps S2000 and S3000 in the above embodiments belong to the same inventive concept as the relevant embodiments of the previous business processing method, the only difference is that the execution subjects of the business processing methods in each embodiment are different. Therefore, other specific implementation methods of steps S2000 and S3000 in the above embodiments, as well as related implementation methods, such as the preset forwarding rules of the target computing power SID, the type of preset extension header, and other specific implementation methods, can refer to the specific implementation methods of the business processing methods in the previous embodiments. In order to avoid redundancy, these implementation methods will not be repeated here.

As shown in Figure 7, Figure 7 is a flowchart of a service processing method provided by another embodiment of the present application, and the service processing method can be, but is not limited to, applied to the second gateway node in the computing network shown in Figure 1. The service processing method can include, but is not limited to, step S4000.

Step S4000: When it is determined that the destination address of the received service message carries the first SID, computing power service addressing is performed according to a preset forwarding rule of the first SID.

In this step, when it is determined that the destination address of the received service message carries the first SID, computing power service addressing is performed according to the preset forwarding rule of the first SID, so that the corresponding computing power network service can be processed at the required network node based on the preset forwarding rule of the first SID. This overcomes the impact of encapsulation defects in related technologies, is conducive to expanding the application scenarios of computing power network services, and can meet the requirements of computing power network service forwarding.

In one embodiment, the preset extension header of the service message carries a computing power identifier, and computing power service addressing is performed according to the preset forwarding rule of the first SID, so that the computing power identifier is extracted from the preset extension header of the service message in subsequent steps, and computing power routing addressing is performed based on the computing power identifier on the basis of the preset forwarding rule of the first SID, that is, the computing power identifier is used as a form of expression of the computing power service in the computing power network. When it is confirmed that the preset extension header of the service message carries the computing power identifier, it means that the computing power network service forwarding can be performed specifically according to the computing power identifier to meet the requirements of computing power network service forwarding.

In one embodiment, the preset forwarding rules of the first SID include but are not limited to: parsing a preset extension header from a business message to obtain a computing power identifier; querying a computing power route according to the computing power identifier to determine a cloud node of the computing power route; determining a next-hop address of the computing power route according to the computing power route; and replacing the first SID with a second SID of the cloud node.

Among them, the preset extension header is parsed from the business message to obtain the computing power identifier, so as to further query the computing power route based on the computing power identifier; the computing power route is queried according to the computing power identifier to determine the cloud node of the computing power route, that is, the cloud node corresponding to the computing power route can be determined, so as to forward the business to the cloud node; the next hop address of the computing power route is determined according to the computing power route, so as to forward the business message based on the next hop address; the first SID is replaced with the second SID of the cloud node to meet the requirements of computing power network business forwarding.

In one embodiment, the computing power type of the first SID is configured as end.c type.

As shown in FIG. 8 , an embodiment of the present application further illustrates step S4000 , which includes but is not limited to step S4100 .

Step S4100: Send a service message to the cloud node according to the next hop address of the computing power routing, so that the cloud node performs computing power service addressing according to the preset forwarding rule of the first SID when determining that the destination address of the service message carries the second SID, wherein the computing power type of the second SID is the same as that of the first SID.

In this step, when the next hop address is determined based on the preset forwarding rule, the business message is sent to the cloud node according to the next hop address of the computing power routing to realize computing power service addressing, and by sending the business message to the cloud node, when the cloud node determines that the destination address of the business message carries the second SID, since the second SID has the same computing power type as the first SID, that is, the preset forwarding rule of the first SID can be used to forward the second SID, it is convenient for the cloud node to perform computing power service addressing according to the preset forwarding rule of the first SID.

It should be noted that since step S4000 and step S4100 in the above-mentioned embodiments belong to the same inventive concept as the relevant embodiments of the previous business processing method, the only difference is that the execution subjects of the business processing methods in each embodiment are different. Therefore, other specific implementation methods of step S4000 and step S4100 in the above-mentioned embodiments, as well as related implementation methods, such as the preset forwarding rules of the first SID, the type of preset extension header, etc., can refer to the specific implementation methods of the business processing method in the previous embodiments. In order to avoid redundancy, these implementation methods will not be repeated here.

The following specific examples are given to more clearly illustrate the working principle of the above-mentioned related embodiments.

Example 1:

As shown in FIG. 9 , FIG. 9 is a schematic diagram of an application scenario of a business processing method provided by an embodiment of the present application.

9, there are two gateway nodes (i.e., Ingress PE and Egress PE) in the network domain, which need to be addressed according to the computing power routing based on the computing power identifier. The end.c type is defined in the Ingress PE and the Egress PE, where end.c1 is used as the gateway SID of the Ingress PE, and end.c2 is used as the gateway SID of the Egress PE. End.c1 and end.c2 use the IGP routing protocol for routing flooding to form a routable SID. The end network cloud processing flow based on the embodiment of the present application is as follows:

First, the computing power SID of the Ingress PE encapsulated on the end side is end.c1, which is encapsulated in the destination address of the user message, and the computing power identifier encapsulates the DOH of the user message.

Then, when the Ingress PE node receives the user message, it takes out the end.c1 in the destination address for routing lookup, and finds that it is the target computing power SID. It then performs computing power routing addressing according to the preset forwarding rules shown in the previous embodiment, that is, it can address by querying the corresponding computing power routing table and IP routing table, and continue to carry DOH for forwarding.

It should be noted that if the traffic is managed in SRV6POLICY mode, the Ingress PE node and the Egress PE node will encapsulate SRH and will not be aware of the target computing power SID. If the traffic is managed in Best-Effort (BE) mode, another layer of IP header can be encapsulated and the target computing power SID will not be perceived.

Then, when the Egress PE node receives the user message, it takes out end.c2 in the destination address for routing lookup, and finds that it is the target computing power SID. It then performs computing power routing addressing according to the preset forwarding rules shown in the previous embodiment, that is, it can address by querying the corresponding computing power routing table and IP routing table, and continue to carry DOH for forwarding.

Then, when the LB in the cloud receives the user message, if the network in the cloud supports SRV6, it can continue to forward it according to the preset forwarding rules of the target computing power SID, or it can forward it according to the ordinary IPV6 message. This can be determined according to the needs in the cloud and is not restricted here.

Example 2:

As shown in FIG. 10 , FIG. 10 is a schematic diagram of an application scenario of a business processing method provided in another embodiment of the present application.

The end.c type is defined in the Ingress PE and the Egress PE, where end.c1 is used as the gateway SID of the Ingress PE, and end.c2 is used as the gateway SID of the Egress PE. end.c1 and end.c2 use the IGP routing protocol for routing flooding to form a routable SID. The end network cloud processing flow based on the embodiment of the present application is as follows.

First, the computing power SID of the Ingress PE encapsulated on the end side is end.c1, which is encapsulated in the destination address of the user message, and the computing power identifier encapsulates the HBH of the user message.

Then, when the Ingress PE node receives the user message, it takes out the end.c1 in the destination address for routing lookup, and finds that it is the target computing power SID. It then performs computing power routing addressing according to the preset forwarding rules shown in the previous embodiment, that is, it can address by querying the corresponding computing power routing table and IP routing table, and continue to carry HBH for forwarding.

Then, when the Egress PE node receives the user message, it takes out end.c2 in the destination address for routing lookup, and finds that it is the target computing power SID. It then performs computing power routing addressing according to the preset forwarding rules shown in the previous embodiment, that is, it can address by querying the corresponding computing power routing table and IP routing table, and continue to carry HBH for forwarding.
