[0061] In the embodiments provided in this application, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0062] To enable those skilled in the art to better understand the embodiments of the present invention, the following description is provided first.

[0063] Computing power has become a crucial infrastructure for digital industries. The shift of computing power to the edge and even beyond the edge has become an industry trend. Simultaneously, with the diversification of industry computing power demands and the enhancement of terminal computing power, ubiquitous computing power will become a new industry paradigm. Under the computing power network architecture, full-granularity computing power at the edge, device, and cloud becomes a resource visible, schedulable, and routable across the entire network. The network is further transforming from traditional topology routing to computing power routing, enabling entirely new network architectures and business deployment and delivery models, thus facilitating the digital transformation of the entire industry. In particular, cloud-based computing resources are shifting from the current closed model to an open model under the computing power network architecture, posing new requirements for the granularity of computing power routing.

[0064] Computing power routing can be broadly categorized into centralized and distributed computing power routing schemes. Centralized computing power routing schemes primarily rely on IPv6+ technologies, such as Segment Routing over IPv6 (SRV6) and Segment Routing (SR) policies based on the IPv6 forwarding plane, to centrally orchestrate routing, achieving end-to-end route connectivity and flexible scheduling of computing power. Distributed routing schemes mainly rely on extending existing intra-domain IGP protocols and inter-domain BGP protocols to facilitate the transmission of computing power information.

[0065] In related distributed computing power network solutions, the announcement of computing power routes is mainly achieved by extending the community attribute of BGP, which transmits the CPU and memory usage of the resource pool to BGP neighbors.

[0066] The notification mechanism for computing power routing is primarily based on service scheduling:

[0067] (1) Multiple nodes in the entire computing power network topology can support service1 and spread the serviceID1 (an anycast) route in the network;

[0068] (2) The Ingress node establishes a Border Gateway Protocol (BGP) peer with the resource pool border gateway. The peers announce the computing power status of the resource pool to each other. The Ingress node integrates the network and computing power status and generates a forwarding table entry for serviceID1.

[0069] (3) When Ingress1 receives a message with the destination address serviceID1, it enters the tunnel according to the aforementioned table entries, performs tunnel decapsulation on the egress router, and schedules the service to the corresponding resource pool.

[0070] Existing routing schemes are mainly based on end-to-end (tunneling) path planning, lacking traffic control schemes for cross-domain scenarios.

[0071] This invention provides a network traffic control method applied to a controller within a first autonomous system (AS). The first AS is connected to a third AS via at least one second AS, and the third AS is connected to at least one computing server. Each computing server is connected to a computing service node, such as... Figure 1 As shown, the method includes:

[0072] Step 101: Obtain the target information of the target router within the first AS and the resource pool computing power information transmitted by the third AS. The resource pool computing power information includes the computing power information of at least one computing service node, and the target information includes the segment routing identifier of the target router.

[0073] For example, such as Figure 2 As shown, the first AS is AS1, the second AS includes AS2 and AS2, and the third AS is AS4. Router R10 in AS4 is connected to router R12 in computing server 1 (or computing proxy module 1), and router R9 in AS4 is connected to router R11 in computing server 2 (or computing proxy module 2). Computing server 1 is connected to computing service node 1, and computing server 2 is connected to computing service node 2.

[0074] In this embodiment of the invention, the controller may specifically be a Software Defined Network (SDN) controller. Optionally, the target router is a router within the first AS that has EPE functionality enabled.

[0075] Optionally, the target information further includes at least one of the following:

[0076] BGP routing information;

[0077] Network transmission information, such as transmission link latency, bandwidth, jitter, etc.;

[0078] Network topology information, for example, Figure 2 The connection relationships between various routers, etc.

[0079] In this embodiment of the invention, BGP Egress Peer Engineering (EPE) is enabled on all egress routers of the first AS, second AS, and third AS. After the router enables BGP EPE, it will automatically assign BGP peer SIDs. The SDN controller in the domain will collect peer SIDs, all BGP routing information, network transmission information, network topology information, and the aforementioned resource pool computing power information from all routers in the domain that have enabled EPE through the BGP Link State (LS) protocol.

[0080] Step 102: Based on the target information of the target router and the computing power information of the resource pool, determine the target computing service node that meets the computing power requirements.

[0081] The specific computing power requirement is determined based on business needs, which may include link latency requirements, packet loss requirements, etc.

[0082] Step 103: Determine the router in the third AS that is connected to the target computing service node as the last-hop egress router, and generate a list of segment identifiers (SIDs) corresponding to the packet forwarding path based on the last-hop egress router. Each SID in the SID list corresponds to a router.

[0083] Step 104: Send the SID list to the ingress router of the first AS.

[0084] like Figure 2 As shown, the ingress router of the first AS is R1. After receiving the SID list, R1 can forward service packets according to the SID list.

[0085] In this embodiment of the invention, the controller of the first AS obtains target information of the target router within the first AS and resource pool computing power information transmitted by the third AS; based on the target information of the target router and the resource pool computing power information, it determines the target computing service node that meets the computing power requirements; it identifies the router in the third AS connected to the target computing service node as the last-hop egress router, and generates a Segment Identifier (SID) list corresponding to the packet forwarding path based on the last-hop egress router; and it sends the SID list to the ingress router of the first AS. Through this scheme, in cross-domain scenarios, a suitable computing service node can be determined based on computing power information, and it replaces the traditional BGP shortest path-based routing method between domains, realizing computing power and traffic control in cross-domain scenarios.

[0086] Optionally, obtaining the resource pool computing power information transmitted by the third AS includes:

[0087] The resource pool computing power information transmitted by the third AS through the second AS is obtained, wherein the resource pool computing power information is carried by a Border Gateway Protocol (BGP) update message.

[0088] Optionally, obtaining the resource pool computing power information transmitted by the third AS through the second AS includes:

[0089] Based on the BGP tag unicast address family, the resource pool computing power information transmitted by the third AS through the second AS is obtained.

[0090] In this embodiment of the invention, the third AS sends a BGP update message carrying resource pool computing power information to the second AS, which then sends the BGP update message to the controller of the first AS.

[0091] For example, such as Figure 2As shown, R11 and R12 serve as the egress routers for computing power proxy module 2 and computing power proxy module 1, respectively. R11 and R12 need to have BGP routing protocol capabilities. R9 establishes BGP neighbor relationships with R11, and R10 establishes BGP neighbor relationships with R12. By defining new BGP path attributes, BGP update messages are passed to at least one of R9 and R10. The process after at least one of R9 and R10 in AS4 receives the computing power information from the peer is as follows (the process for R9 and R10 is the same, and R9 is used as an example below): The AS4 egress router R9 needs to allocate a BGP prefix segment identifier (SID) using RFC8669, such as BGP prefix SID, and enable the BGP label unicast address family (based on the BGPLU protocol). Inter-domain routers establish BGP neighbors, and intra-domain BGP routers establish IBGP neighbors. On R9, through the aforementioned BGP update message, and through message exchange between neighbors, R1 can eventually receive R9's BGP prefix-SID and the metric information of the computing resource pool attached to R9.

[0092] Optionally, in this embodiment of the invention, the computing power information of the computing service node is a comprehensive computing power index obtained based on the initial computing power information of the computing service node. For example, the computing power proxy module normalizes the transmission computing power information of the computing service node to obtain a comprehensive computing power index (metric), where a larger metric value indicates higher priority. Specifically, the PageRank algorithm can be used for normalization.

[0093] Optionally, the computing service node can collect the initial computing power information of the computing service node through the RESTful protocol.

[0094] The aforementioned initial computing power information includes at least one of the following: CPU utilization, memory utilization, GPU utilization, storage capacity, and energy efficiency information of computing service nodes.

[0095] Optionally, the newly defined BGP path attributes are as follows:

[0096] RFC 4271 defines that the type of a path attribute occupies 2 bytes and is divided into two fields: Flags (attribute label) and Type Code (attribute type value). Figure 3 As shown.

[0097] The first three bits of Attr.Flags are 0 (indicating optional), T (indicating transmission), and E, respectively. In this embodiment of the invention, the three bits 0, T, and E should be set to 1. 0 = 1 and T = 1 indicate that the attribute is an optional transmission attribute, meaning that devices that do not recognize the attribute will still receive it and forward it to other BGP neighbors; E = 1 indicates that the attribute length is extended to 2 bytes.

[0098] Currently, in the IANA definition, numbers 41-127 are unused. The type code for the computing power routing attribute is defined as follows, with the normalized metric attribute type value temporarily set to 127.

[0099] BGP update messages or segmented routing (SR) messages have the following message structure: Figure 4 As shown, all parameters except metric are existing parameters in the BGP update message, and will not be described in detail in this embodiment of the invention. For example, SAFI is Labeled Unicast; NLRI is 1.1.1.3 / 32; Label is 16003; Prefix-SID is 3.

[0100] Optionally, after sending the SID list to the ingress router of the first AS, the method further includes:

[0101] Replace the destination IP address in the service message received by the ingress router with the IP address of the router in the target computing server, where the target computing server is the computing server connected to the last-hop egress router.

[0102] For example, if the last-hop exit router is R9, then the target computing server is server 2 (i.e., computing proxy module 2).

[0103] Optionally, sending the SID list to the ingress router of the first AS includes:

[0104] The SID list is sent to the ingress router of the first AS via the gateway protocol and the path calculation unit communication protocol PCEP.

[0105] In this embodiment of the invention, BGP EPE function can be enabled on all egress routers. After the router device enables EPE function, it will automatically assign BGP peer SID, which corresponds to the segment route identifier mentioned above. The SDN controller in the domain will collect Peer SID, all BGP routes, network information, topology information, and resource pool computing power information transmitted by the third AS from all routers in the domain that have enabled EPE function through the BGP-LS protocol. The controller determines the last-hop egress device of the computing power resource pool that meets the computing power requirements according to service needs and generates a SID list. The controller distributes the SID-LIST to the forwarding entry device R1 through the gateway protocol and PCEP protocol. On R1, the destination IP of the service packet is replaced with the IP address of device R11 connected to R9.

[0106] In this embodiment of the invention, the controller of the first AS obtains target information of the target router within the first AS and resource pool computing power information transmitted by the third AS; based on the target information of the target router and the resource pool computing power information, it determines the target computing service node that meets the computing power requirements; it identifies the router in the third AS connected to the target computing service node as the last-hop egress router, and generates a Segment Identifier (SID) list corresponding to the packet forwarding path based on the last-hop egress router; and it sends the SID list to the ingress router of the first AS. Through this scheme, in cross-domain scenarios, a suitable computing service node can be determined based on computing power information, and it replaces the traditional BGP shortest path-based routing method between domains, realizing computing power and traffic control in cross-domain scenarios.

[0107] like Figure 5 As shown, this embodiment of the invention also provides a network traffic control method applied to a computing server, wherein the computing server is connected to a third AS, the computing server is connected to a computing service node, and the third AS is also connected to at least one second AS, each second AS being connected to a first AS. The method includes:

[0108] Step 501: Obtain the computing power information of the computing service node.

[0109] Step 502: Send the computing power information to the first AS through the third AS and the second AS.

[0110] In this embodiment of the invention, the third AS sends the computing power information of the computing service node to the first AS through the third AS and the second AS, enabling the first AS to determine the target computing service node that meets the computing power requirements based on the target router's target information and the resource pool's computing power information. The router in the third AS connected to the target computing service node is identified as the last-hop egress router, and a Segment Identifier (SID) list corresponding to the packet forwarding path is generated based on the last-hop egress router. The SID list is then sent to the ingress router of the first AS. This scheme enables the determination of a suitable computing service node based on computing power information in cross-domain scenarios, and replaces the traditional BGP shortest path-based routing method between domains, achieving computing power and traffic control in cross-domain scenarios.

[0111] Optionally, sending the computing power information to the first AS via the third AS and the second AS includes:

[0112] Based on BGP update messages, the computing power information is sent to the first AS through the third AS and the second AS.

[0113] The BGP update message has been described in the above embodiments and will not be repeated here.

[0114] Optionally, obtaining the computing power information of the computing service node includes:

[0115] Obtain initial computing power information of the computing service node, wherein the initial computing power information includes at least one of the following: CPU utilization rate, memory utilization rate, GPU utilization rate, storage capacity, and energy efficiency information of the computing service node;

[0116] The initial computing power information of the computing service node is normalized to obtain a comprehensive computing power index;

[0117] The comprehensive computing power index is determined as the computing power information of the computing service node.

[0118] In this embodiment of the invention, the initial computing power information of computing service nodes can be collected through the RESTful protocol, and the comprehensive computing power index can be obtained by normalization based on the PageRank algorithm.

[0119] In this embodiment of the invention, the third AS sends the computing power information of the computing service node to the first AS through the third AS and the second AS, enabling the first AS to determine the target computing service node that meets the computing power requirements based on the target router's target information and the resource pool's computing power information. The router in the third AS connected to the target computing service node is identified as the last-hop egress router, and a Segment Identifier (SID) list corresponding to the packet forwarding path is generated based on the last-hop egress router. The SID list is then sent to the ingress router of the first AS. This scheme enables the determination of a suitable computing service node based on computing power information in cross-domain scenarios, and replaces the traditional BGP shortest path-based routing method between domains, achieving computing power and traffic control in cross-domain scenarios.

[0120] like Figure 6 As shown, this embodiment of the invention also provides a network traffic control device applied to a controller within a first autonomous system (AS).

[0124] The first sending module 604 is used to send the SID list to the ingress router of the first AS.

The target computing server is the computing server connected to the last hop egress router.
