[0098] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present disclosure without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0099] The term "comprise" and any variations thereof in the specification and claims of the present disclosure are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to the process, method, product, or apparatus. In addition, the use of "and / or" in the specification and claims to indicate at least one of the connected objects, such as A and / or B, means that A alone, B alone, and both A and B are included.

[0100] In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0101] As shown in Figure 1, the computing power perception and routing system architecture mainly includes:

[0102] (1) Computing Network Management and Control Center: Responsible for collecting and maintaining global network and resource topology information, configuring computing resource perception and reporting strategies, and maintaining the unified computing network database.

[0103] (2) Computing power routing node: responsible for computing power notification and computing power discovery, and making computing power perceptible, schedulable and manageable.

[0104] (3) Computing nodes: nodes that provide data processing and computing services. Specific deployment forms include but are not limited to cloud, edge, and end, as well as future computing and network-integrated device nodes.

[0105] Currently, the team has achieved multi-dimensional resource perception capabilities, including computing power, network, and business, as well as cross-domain collaborative scheduling capabilities for integrated computing and network. Breakthroughs have been made in key technologies such as computing power notification and computing and network collaborative scheduling mechanisms. Based on protocol extensions such as the Border Gateway Protocol (BGP), Open Shortest Path First (OSPF), Interior Gateway Protocol (IGP), and Network Configuration Protocol (NETCONF), the team has implemented an integrated computing and network perception protocol. Based on the mainstream Internet Protocol Version 6 (IPv6) / Segment Routing over IPv6 (SRV6) protocol extensions based on the IPv6 forwarding plane, the team has proposed multiple routing and forwarding solutions, including edge updates, hop-by-hop updates, and Software Defined Network (SDN) control and delivery. This has formed a series of computing power routing solution technologies for overlay and underlay networks, supporting centralized, distributed, and hybrid deployment solutions.

[0106] As shown in Figure 2, related technologies have proposed using the Service Function Chaining (SFC) BGP control plane, or SFIR routing, to advertise metrics information from the Computing-Aware Traffic Steering (CATS), the IETF standard for computing-aware traffic steering. Ingress routers use this CATS information to steer traffic for service flows. This solution is based on a simple extension of existing BGP Request for Comments (RFC) and advertises all traffic globally. It cannot adapt notification policies to specific information, nor can it implement on-demand notification based on services.

[0107] Referring to Figure 3, an embodiment of the present disclosure provides a communication method, the execution subject may be a first node, the first node may be a computing power routing egress gateway (Egress), and the specific steps include: Step 301.

[0108] Step 301: The first node sends first information, where the first information includes at least one of the following: service capability information, and service or resource status information.

[0109] It should be noted that the service in this embodiment can be replaced by computing power or computing power service, that is, the service capability information can also be called computing power capability information or computing power service information, and the service status information can also be called computing power status information or computing power service status information.

[0110] It can be understood that service capability information is static information, and service or resource status information is dynamic information.

[0111] In one embodiment of the present disclosure, the first node sending the first information includes:

[0112] The first node sends the first information via a Border Gateway Protocol (BGP) message of an IPv6 or IPv4 address cluster.

[0113] In another embodiment of the present disclosure, the first node sending the first information includes:

[0114] The first node sends a first message via a BGP message of a newly defined address cluster, where the first message includes second information and the first information, where the second information is used to indicate a route type (Route Type).

[0115] In this embodiment, by extending the BGP message of the address cluster, integrated perception of computing network information is achieved, which can meet the needs of new technological innovations while reducing the impact on existing address families.

[0116] 7 , the format of the first message may include: Route Type, length (Length), route type specific (variable) (Route Type specific (variable)).

[0117] In this embodiment, a new CATS address cluster is defined in BGP. Specifically, the Network Layer Reachability Information (NLRI) of the CATS message defines three types of CATS routes, as shown in Figures 8, 9, and 10:

[0118] (1) Route Type 1: generated and sent by the computing power routing egress gateway (Egress).

[0119] Category 1 routing, also known as topology routing, is used to publish service capability information, such as C-SMA (CATS Service Metric Agent). Service capability information includes but is not limited to at least one of the following: service identifier (CS-ID), service domain name, service type, service energy consumption, and service cost (cost), enabling the computing power routing ingress gateway to be mapped to the CS-ID based on service characteristics.

[0120] (2) Route Type 2: Generated and sent on demand by the computing power routing ingress gateway. Route Type 2 is used for service subscriptions. Only the computing power routing ingress gateway that has sent the subscription message will receive status information for a specific service or resource.

[0121] Type 2 routing can also be called on-demand routing subscription. Based on business needs, you subscribe to the status information of specific services or resources. The subscription message can include parameters such as notification policy and notification period.

[0122] (3) Route Type 3: Generated by the computing power routing egress gateway, it publishes status information of specific services or resources and is sent only to subscribers. It can be used in conjunction with the subscription message of Route Type 2.

[0123] Type 3 routing, also known as refined routing, advertises status information of specific services or resources. The status information may include load size, number of available service connections, available resource size, etc.

[0124] In this embodiment, Class 1 routing, Class 2 routing, and Class 3 routing are defined, which support computing power notifications of different strategies, implement on-demand routing, and reduce the overhead of notifications.

[0178] In this embodiment, the third node can subscribe to the third information from the fourth node to meet the differentiated needs of users and better provide differentiated user services.

[0179] Two implementation methods of the present disclosure are described below in conjunction with Example 1 and Example 2.

[0180] Example 1: There is only one type of routing.

[0181] For low-frequency refresh services that are less sensitive to the refresh frequency of service capability information, in addition to computing power service attribute information, service capability information can be abstracted into a comprehensive service metric, similar to the network service cost. By publishing service metric information, the processing burden of equipment is reduced, computing power services can be quickly launched, and business needs can be met. See Figure 11. The specific workflow is as follows:

[0182] 1. The egress gateway (GW) obtains service capability information, advertises the service capability information through type 1 routing, and passes it to the ingress GW.

[0183] Based on its perception of computing power information, the Ingress GW generates a computing power routing information table (Routing Information Base, RIB) on the control plane. When the computing power routing ingress gateway receives the first packet of a service flow, the control plane triggers the generation of a computing power flow forwarding table to guide the forwarding of subsequent packets of the service flow.

[0184] 2. The client sends a data packet to the Ingress gateway, which maps the CS-ID based on the service capability information.

[0185] 3. The CATS Traffic Classifier (C-TC) component of the ingress gateway first classifies the traffic and searches the computing power flow forwarding table (for example, the forwarding information base (FIB) table) based on the traffic quintuple. If the computing power flow forwarding table exists, it directly obtains the egress GW address and the remote server address based on the computing power flow forwarding table record.

[0186] 4. If the computing power flow forwarding table does not exist, select the corresponding destination service node based on the computing power cost and generate the computing power flow forwarding table.

[0187] 5. Encapsulate the data message according to the existing IPv6 technology and send it to the Egress gateway after encapsulation.

[0188] The computing power RIB maintains information about instances corresponding to computing power services, including network parameters, computing power parameters, next hop (computing power routing gateway), service instance ID (BID), and other information. The full computing power RIB table maintains information about all instances corresponding to a service (see Figure 12). The optimal RIB table maintains information about the optimal instance corresponding to a service (see Figure 13).

[0189] The computing power flow forwarding table maintains the forwarding information corresponding to the computing power flow, including the x-tuple used to uniquely represent the flow, the business instance (BID), the outbound interface, the next hop (computing power routing egress gateway), the expiration time, and other information.

[0190] Example 2: Type 1 routing, type 2 routing, and type 3 routing work together.

[0191] Compared to Example 1, this embodiment targets very important computing power users, can perceive the business status and implement refined business scheduling. At the same time, it can subscribe to notifications on demand, reducing the notification overhead to a minimum. Referring to Figure 14, the specific workflow is as follows:

[0192] 1. The egress GW starts the service, advertises the service capability information through type 1 routing, and passes it to the ingress GW.

[0193] 2. The client sends a data packet to the Ingress gateway, which maps the CS-ID based on the service capability information.

[0194] 3. The C-TC component of the ingress gateway first classifies the traffic and searches the computing power flow forwarding table based on the traffic five-tuple. If the computing power flow forwarding table exists, it directly obtains the egress GW address and the remote server address based on the computing power flow forwarding table record.

[0195] 4. If the computing power flow forwarding table does not exist, send a type 2 route to the route reflector (RR) to subscribe to the metric information of this CS-ID;

[0196] 5. The C-SMA component in the Egress GW collects the computing service ID (CS-ID), server address (as CIS-ID), and service metrics through broadcast.
