The routing information includes at least one of the following information: information of the destination node (e.g., IP), information of the destination path (e.g., specified or set path information, such as IP including only the destination node, IP of the intermediate node being a path of the virtual information).
Optionally, the routing message table may further include: resource information, the resource information including at least one of: available computing resource information and available network resource information.
In this step, the network device may generate the routing message table based on one or more of service distribution, network resources, and computing resources. Wherein, the destination IPs in the routing message table are ordered according to preset rules, and the preset rules include any one of the following: the user prefers to rank the power or network information from superior to inferior. By the method, the established transmission path can better meet the requirements of users, and the service is dispatched to the optimal target service node through the optimal path.
The service request of the user (or called as the client) includes a service requirement, a service ID, and the like. The service requirements comprise computing power requirements, time delay, bandwidth and the like.
When the service request arrives at the network device, the network device addresses based on the serviced service ID. And the network equipment establishes and maintains a forwarding routing table based on the service ID according to the real-time resource condition. Meanwhile, the network device may optionally maintain the path message according to a network policy. The network device may then select IP, SRV6, or GRE (Generic Routing Encapsulation) for data transmission.
Specifically, in this step, a destination service node may be determined according to the service requirement and the routing message table, and then a forwarding table facing to a service Flow based on a Flow ID may be generated according to the destination service node. Then, the network device may further generate a sending packet, where the sending packet carries the source IP, the IP of the destination service node, and load information (payload).

The network device may refer to a first-hop network device in a transmission path, such as a gateway, a router, or the like. As shown in fig. 2, the method comprises the following steps:
In this step, the network device may generate the routing message table based on one or more of service distribution, network resources, and computing resources. Wherein, the destination IPs in the routing message table are ordered according to preset rules, and the preset rules include any one of the following: the user prefers to rank the strength and network information from superior to inferior. By the method, the established transmission path can better meet the requirements of users, and the service is dispatched to the optimal target service node through the optimal path.
In this step, the network device may dynamically update the routing message table according to the path update reference information, such as the resource state measured by the control plane or the in-band OAM (Operation Administration and Maintenance) carried along the path.
Specifically, the update may be performed in the following manner:
in the first mode, the destination IP is not changed for network route update. In this manner, at least one path to the destination service node is obtained according to the network resource status, and the routing message table is updated using the at least one path. In a specific application, the network device may select different network paths to reach the optimal destination IP service node in real time according to the network resource state, for example, perform multi-path sharing by using SR-policy (Segment Routing policy).
The second way, network route update of destination IP update. In this manner, the network device re-determines the destination service node and determines the transmission path to the re-determined destination service node, and then updates the routing message table according to the re-determined destination service node and the transmission path to the re-determined destination service node. In a specific application, when the best service IP fails or is difficult to support the current computing service, the network device reselects the best service node according to the latest resource information, and updates the destination service node and the network path, thereby implementing the update of the end-to-end path.
Referring to fig. 3, fig. 3 is a flowchart of a computing power aware path establishment method and data transmission according to an embodiment of the present invention. In the embodiment of the invention, network equipment (such as computational network equipment or nodes) generates a routing message table based on service ID according to information announcements such as service distribution, network resources, computational resources and the like, wherein the routing message table comprises the service ID and a destination IP. The order of the destination IP can be arranged according to the order of the power and the network information from superior to inferior or according to the rules of the user preference service IP and the like. The route may then be established based on IPv6 or SRV6 routing protocols.
In the embodiment shown in fig. 3, a force-aware path establishment method and a data transmission method based on the IPv6 protocol are shown. The sending node maintains a traffic flow, which may be represented by a flow ID (destination IP, destination port, source IP, source port, protocol type). As shown in fig. 3, the method comprises the following steps:
step 301, the user sends a service request carrying the source IP, flow ID, service requirement, and destination address IP as service ID to the first hop network device R1.
Step 302, the first hop network device R1 determines a destination service node according to the generated service ID-based routing message table and service requirement, and generates a Flow ID-based forwarding table facing to the service Flow.
Referring to fig. 4, fig. 4 is a flowchart of a computing power aware path establishment method and data transmission provided in an embodiment of the present invention. In the embodiment of the invention, network equipment (such as computational network equipment or nodes) generates a routing message table based on service ID according to information announcements such as service distribution, network resources, computational resources and the like, wherein the routing message table comprises the service ID and a destination IP. The order of the destination IP can be arranged according to the order of the power and the network information from superior to inferior or according to the rules of the user preference service IP and the like. The route may then be established based on IPv6 or SRV6 routing protocols.
In this embodiment, a service ID-based routing message table and a Flow ID-based forwarding table for traffic flows are generated and maintained at the network device ingress R1, where the routing information may be path information with low latency or high bandwidth generated according to user requirements and by using SR-policy.
In the embodiment of fig. 4, a force-aware path establishment method and a data transmission method based on the SRv6 protocol are described. The sending node maintains a traffic flow, which may be represented by a flow ID (destination IP, destination port, source IP, source port, protocol type). As shown in fig. 4, the method comprises the following steps:
step 401, the user sends a service request carrying the source IP, flow ID, service requirement, and destination address IP as service ID to the first hop network device R1.
Step 402, the first hop network device R1 determines a destination service node according to the generated service ID-based routing message table and service requirements, and at the same time, selects a transmission path according to a policy, and generates a Flow-oriented forwarding table based on the Flow ID.
In a specific application, for a long link service, the network device may update the path information in the routing message table in real time according to the network load condition of the control plane. In the updating process, the updating can be performed according to the calculation power of BGP (Border Gateway Protocol)/IGP (Interior Gateway Protocol) and the network topology information, and also according to the resource information of OAM carried along with the path.
The destination IP is unchanged, and the network route is updated: the entrance gateway (R1) can select different network paths to reach the best destination IP service node according to the network resource state in real time. Such as multipath sharing using SR-policy. For example, when R1 receives service data carrying a service ID, it may select a more optimized network path12 according to the latest service ID routing message table under the condition that the destination IP1 is not changed, and schedule the service to the optimal path for network transmission.
Updating a destination IP and network routing: if the best service IP fails or the current computing service is difficult to support, the entrance gateway can reselect the best service node according to the latest resource information, update the destination service node and the network path, and update the end-to-end path. For example, when R1 receives service data carrying a service ID, it may update the destination IP1 to IP2 according to the latest service ID routing information table, select a destination service node IP2 and an updated network Path21 that meet the requirements, and schedule the service to the latest Path for network transmission.
As can be seen from the above description, the embodiments of the present invention can achieve the following effects:
1. the client addresses through the service ID, the network side adjusts the network transmission path and the target service node in real time according to the network computing state, and generates and maintains a routing forwarding table based on the service ID, so that the transmission through the optimal network path is realized, and the end-to-end optimal network and the computing power service are provided.
2. On the basis of determining the target service node, the network side can dynamically adjust the network path according to the network computing resource condition, and really realize that the optimal target service node is addressed through the optimal path, thereby improving the network efficiency of an operator while ensuring the service quality.
3. Once a target service node fails or cannot meet service requirements during a session, the target service node can actively notify an application layer to switch to other service nodes through network layer sensing without waiting for timeout of a Transmission Control Protocol (TCP), so that service switching can be realized quickly, and optimal user experience is ensured.
