Detailed Description

The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, not all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by one of ordinary skill in the art based on the present disclosure are within the scope of the present disclosure.

The embodiment of the disclosure provides a computing power resource scheduling method, which is applied to a first PE device in an MPLS L3VPN network, as shown in fig. 1, and comprises the following steps:

S101, receiving first BGP VPN route information sent by second PE equipment which has a BGP VPN neighbor relation of a border gateway protocol in an MPLS L3VPN network.

The first BGP VPN routing information includes computing power resources of a first service node connected to the second PE device.

The computing power resources may include at least one of central processor (Central Processing Unit, CPU) computing power, graphics processor (Graphics Processing Unit, GPU) computing power, data processor (Data Processing Unit, DUP) computing power, and memory information, as well as other types of computing power resources, which are not limited by the disclosed embodiments.

Because the first PE device and the second PE device have established BGP VPN neighbor relation, the first PE device and the second PE device can carry out route notification between each other, and when the first service node is on line in the second PE device, the second PE device can notify the computing power resource of the first service node to the first PE device through the routing information of the BGP VPN.

In addition, after the second PE device learns the BGP VPN routing information advertised by the other PE devices, if the learned BGP VPN routing information and the first PE device belong to the same VPN, the second PE device also advertises the BGP VPN routing information learned by the second PE device to the first PE device.

In the embodiment of the disclosure, there may be a plurality of PE devices having BGP VPN neighbor relations with the first PE device in the MPLS L3VPN network, and after receiving the first BGP VPN route information, the first PE device may further send the first BGP VPN route information to other PE devices having BGP VPN neighbor relations with the first PE device.

The first PE device may receive a border gateway protocol update (Border Gateway Protocol update, BGP update) message sent by the second PE device, where the BGP update message carries first BGP VPN routing information.

S102, generating a routing table item according to the first BGP VPN routing information, and adding the generated routing table item to a routing table.

The first PE device may store the generated routing table entry in a routing table of the VPN instance, and since the first BGP VPN routing information includes the computing resources, the routing table entry generated based on the first BGP VPN routing information also includes the computing resources.

S103, when the service message is received, determining a plurality of forwarding paths of the service message in the MPLS L3VPN network based on the routing table.

Optionally, after receiving the service packet, the first PE device may select, based on a destination address of the service packet, a plurality of forwarding paths capable of reaching the destination address.

S104, selecting a target forwarding path from a plurality of forwarding paths based on the computing power resources corresponding to each forwarding path.

S105, forwarding the service message through the target forwarding path.

By adopting the embodiment of the disclosure, the first PE device can generate the routing table item according to the received first BGP VPN routing information and store the routing table item in the routing table, and the generated routing table item also comprises the computing power resource because the first BGP VPN routing information comprises the computing power resource. When the first PE device receives the service message, a plurality of forwarding paths can be determined according to the routing table, and a target forwarding path is determined according to the computing resources corresponding to each forwarding path, and the computing resources in the MPLS L3VPN network can be reasonably scheduled due to the fact that the computing resources are referenced in the process of selecting the target forwarding path, so that the fact that the forwarding path with lower computing resources is selected for the service message is avoided, and the processing efficiency of the service message is improved.

In addition, in the related art, the power computing network generally uses the controller to uniformly manage each node in the power computing network, that is, each node reports the power computing resource to the controller, and then the controller performs uniform power computing resource scheduling. In a large-scale MPLS L3VPN network, information synchronization and scheduling are required to be automatically performed among PE devices based on network information, and a centralized management mode of a controller cannot support information and synchronization among the PE devices, so that a traditional computing resource scheduling method cannot be applied to the MPLS L3VPN network. In the embodiment of the disclosure, by carrying the computational power resources in the BGP VPN routing information, the PE device may select a forwarding path for the service packet based on the computational power resources, so as to implement the computational power resource scheduling for the MPLS L3VPN network.

In some embodiments, the step S104 of selecting a target forwarding path from the plurality of forwarding paths based on the computing power resources corresponding to each forwarding path may be implemented as:

and selecting a target forwarding path with the most calculation force resources from the plurality of forwarding paths based on the calculation force resources corresponding to each forwarding path.

After determining a plurality of forwarding paths matched with the destination address of the service message according to the routing table, the first PE device may select a forwarding path with the most destination of the computing resources from the plurality of forwarding paths based on the computing resources stored in the routing table.

In the embodiment of the present disclosure, the target forwarding path with the most computing power resources may be selected according to actual needs, for example, when the service packet received by the first PE device needs to be processed by using a larger CPU computing power resource, the CPU computing power resources in the computing power resources corresponding to the multiple forwarding paths may be compared at this time, and the forwarding path with the most CPU computing power resources is selected from the multiple forwarding paths as the target forwarding path.

For another example, when the service packet received by the first PE device needs to be processed by using a larger GPU power resource, the GPU power resource in the power resources corresponding to the multiple forwarding paths may be compared at this time, and the forwarding path with the largest GPU power resource is selected from the multiple forwarding paths as the target forwarding path.

By adopting the embodiment of the disclosure, the service message is processed by the service node with the most computing power resources corresponding to the plurality of forwarding paths by comparing the computing power resources of the plurality of forwarding paths and taking the forwarding path with the most computing power resources as the target forwarding path, so that the processing efficiency of the service message is improved, and the computing power resources can be reasonably distributed.

In some embodiments, the first PE device may further perform path selection based on a preset path selection rule, and if two or more equivalent forwarding paths are selected, select a path with the most computing power resources from the equivalent forwarding paths as the target path. The preset path selection rule may be any BGP routing rule in the related art, for example, may be a longest mask matching rule or a path length shortest rule.

By adopting the method, the target forwarding path suitable for the service message can be selected by combining the computing power resource and other preset path selection rules, and the service quality can be improved.

In another embodiment of the present disclosure, the first PE device may also be connected to a service node, and when a second service node to which the first PE device is connected is online, the first PE device may send second BGP VPN routing information to the second PE device, where the second BGP VPN routing information includes computing power resources of the second service node. The PE devices which are BGP VPN neighbors can carry the computing power resources of the service nodes connected with the PE devices when the PE devices advertise the routing information, so that the PE devices can select paths based on the computing power resources, and reasonable scheduling of the computing power resources is realized.

The first PE device may send a BGP update message to the second PE device, where the BGP update message includes second BGP VPN routing information.

Accordingly, when the second service node connected with the first PE device is disconnected, a BGP VPN route withdrawal message may be sent to the second PE device, where the BGP VPN route withdrawal message includes a computational power resource of the second service node, so that the second PE device deletes a routing table entry generated based on the second BGP VPN route information.

The second service node connected to the first PE device may not be available or the computing power of the service node may be transferred to other service nodes, where the second service node cannot provide a corresponding service, that is, the second service node is offline.

The BGP VPN route withdrawal message may be a BGP update message, and the first PE device may carry second BGP VPN route information in the BGP update message, and then send the BGP update message to the second PE device.

By adopting the embodiment of the disclosure, when the second service node is offline, the second PE device can delete the routing table item generated by the second BGP VPN routing information in time in the routing table by sending the BGP VPN routing revocation message, so that the second PE device is prevented from mistransmitting the service message of the client to the offline second service node, and the forwarding accuracy of the service message is improved.

In another embodiment of the present disclosure, the second BGP VPN routing information includes a multiprotocol network layer reachability information (Multiprotocol Reachable NLRI, mp_reach_nlri) attribute field, and the mp_reach_nlri attribute field includes a computing power resource of the second service node.

In this embodiment of the present disclosure, a multiprotocol border gateway protocol (Multiprotocol extensions for BGP-4, MP-BGP) may be specifically used to transfer BGP VPN route information, that is, the first BGP VPN route information and the second BGP VPN route information may both be transferred by MP-BGP. Specifically, the mp_reach_nlri field included in the MP-BGP may be extended, and the extended mp_reach_nlri field carries the computing resource information.

Wherein, the MP-BGP attribute is a group of attribute fields describing BGP prefix characteristics, and the common attributes in the MP-BGP attribute comprise:

ORIGIN (ORIGIN);

as_path (AS PATH);

NEXT HOP (NEXT HOP);

Multi_exit_disc (MULTI-EXIT authentication);

local_pref (LOCAL priority);

ATOMIC_ AGGREGATE (ATOMIC aggregation);

AGGREGATOR (polymerizer);

Community (group);

ORIGINATOR _id (originator identification);

Cluster_list (CLUSTER LIST);

MP_REACH_NLRI (Multiprotocol Reachable NLRI Multi-protocol network layer reachability information)

MP_ UNREACH _NLRI (Multiprotocol Unreachable NLRI, multi-protocol network layer unreachable information).

The format of the mp_reach_nlri field is shown in fig. 2, where the left part in fig. 2 is a field originally included in the mp_reach_nlri field, and the right part in fig. 2 is a field content of the custom extension in the embodiment of the present disclosure, which is used to carry the computing power resource information.

The mp_reach_nlri field specifically includes: ADDRESS FAMILY IDENTIFIER (address family identifier), subsequencent ADDRESS FAMILY IDENTIFIER (concurrent address family identifier), length of Next Hop Network Address (length of next hop network address), network Address of Next Hop (next hop network address), reserved field) and Network Layer Reachability Information (network layer reachability information, hereinafter referred to as NLRI).

Wherein, NLRI field includes: prefix Length, label Stack, route Distinguisher, NLRI IP Prefix. In addition, in the embodiment of the present disclosure, the computational resource field is further extended in the NLRI, that is, the NLRI field further includes a CPU-resource field, a GPU-resource field, a DPU-resource field, and a Memory-resource field. The CPU resource field is used for bearing CPU computing power resources, the GPU resource field is used for bearing GPU computing power resources, the DPU resource field is used for bearing DPU computing power resources, and the memory resource field is used for bearing memory resources.

It should be noted that, in the embodiment of the present disclosure, the content of the extended computing power resource field may be set according to actual needs, and fig. 2 only illustrates an example of extending computing power resource fields such as CPU resources, GPU resources, DPU resources, and memory resources in the NLRI field, and in actual application, the NLRI field may be extended based on computing power resources that need to be scheduled in actual use, so that the NLRI field carries computing power resources that need to be scheduled.

By adopting the embodiment of the disclosure, the MP_REACH_NLRI field is expanded, and then, the first PE device can carry the computational resources in the process of advertising BGP VPN route information to the second PE device, so that a message for sending the computational resources is not required to be additionally established, the message structure is not required to be changed, the computational information is transmitted in the MPLS tunnel between the PEs under the condition that an intermediate link between the two PEs is not perceived, the end-to-end transmission of the computational resources is realized, the intermediate link is not required to identify and process the computational resources, and the network resources are saved.

As shown in fig. 3, fig. 3 is an exemplary schematic diagram of BGP VPN routing information transfer in an MPLS L3VPN network provided by an embodiment of the present disclosure, and fig. 3 only illustrates that the MPLS network includes four PE devices PE1, PE2, PE3, and PE4, and BGP VPN neighbor relations have been established between adjacent PE devices and belong to the same VPN.

Each PE device has a pool of computational resources, the pools of computational resources for PE1, PE2, and PE3 are exemplarily shown in fig. 3, and the computational resources of the service node on-line at the PE device constitute the pool of computational resources for the PE device.

And, each PE device may maintain a computing resource table and a computing resource routing table for computing resources of its own connected service node, as well as for computing resources learned from other PE devices.

Specifically, taking PE1 as an example, if the PE1 has a service node 1 on line, the PE1 may add the computing power resource of the service node 1 to the computing power resource table, and store the routing information including the computing power resource of the service node in the computing power resource routing table. And PE1 can send BGP VPN route information to PE2 and PE4, the BGP VPN route information includes computing power resources of service node 1, PE2 and PE4 can generate route list item according to the BGP VPN route information, and the generated route list item is added into self-maintained computing power resource route list.

Each PE device may send BGP VPN routing information generated and received separately to neighboring PE devices, respectively. For example, PE3 may send BGP VPN routing information and its own BGP VPN routing information received from PE2 to PE4, and in the foregoing process, each PE node may generate a routing table entry according to the received BGP VPN routing information, and store the routing table entry in the computing resource routing table.

Furthermore, when each PE device receives a service packet, a forwarding path may be selected for the service packet based on a computing power resource routing table maintained by itself, as shown in fig. 4, and fig. 4 is an exemplary schematic diagram of a forwarding path selection method provided in an embodiment of the disclosure. In fig. 4, only three PE devices including PE1, PE2, and PE3 are taken as an example to illustrate, where service nodes connected by PE1 and PE2 are service nodes of service a, and PE3 is connected to a client, and when the client sends a service packet requesting access to service a to PE3, PE3 determines two forwarding paths to service a according to a computing resource routing table, and then selects a forwarding path with more computing resources from the two forwarding paths based on computing resources as a target forwarding path. Therefore, the routing and message forwarding based on the computational power resources are realized, the computational power resources of the MPLS L3VPN network are fully utilized, the shortage of the computational power resources of forwarding paths selected for the service messages can be avoided, and the processing efficiency of the service messages can be improved.

As shown in fig. 5, fig. 5 is an exemplary interaction flow chart of a computing resource scheduling method according to an embodiment of the disclosure, taking PE1 and PE2 as an example for illustration, including the following steps:

S501, PE1 and PE2 establish BGP VPN neighbor relations.

S502, the service node reports the calculation power resource.

When the service node is online, the service node may report its own computing power resources to PE 1.

S503, the client is online.

The embodiment of the present disclosure does not limit the execution order among S501, S502, and S503, and may be executed in sequential order or may be executed in parallel.

S504, PE1 generates a computational force route according to the received computational force resource, and transmits the computational force route to PE 2.

The power route is the first BGP VPN route information in the foregoing embodiment.

S505, PE2 generates VPN route according to the IP address of the client, and transmits the VPN route to PE 1.

The embodiment of the present disclosure does not limit the execution sequence between S504 and S505, and may be executed in sequential order or may be executed in parallel.

S506, the PE2 accesses the service node according to the calculation route.

When the PE2 receives a service packet from the client, a target forwarding path may be determined according to a destination address in the service packet and a size of a computing resource corresponding to each computing route, and in fig. 5, the target forwarding path is taken as an example of a path of the PE2-PE 1-service node.

S507, the service node goes offline and the calculation route is withdrawn.

When the service node connected with the PE1 is unavailable or the computational power migration occurs, the PE1 sends a computational power route withdrawal message to the PE2 device to withdraw the computational power route.

By adopting the embodiment of the disclosure, the computing power route is announced by establishing the BGP VPN neighbor relation between the PE1 and the PE2 and further by the BGP VPN neighbor relation, and when the PE2 selects the forwarding path, the computing power resource corresponding to the computing power route is used as one of the basis for determining the target forwarding path, so that the computing power resource of the determined target forwarding path is sufficient, and the reasonable utilization of the computing power resource is realized.
