Step 101, obtaining a service-oriented routing message table, wherein the routing message table at least comprises service information and routing information.
Wherein the information of the service includes at least one of the following information: service ID (service ID), function ID (Function ID), number of service connections, etc. The routing information includes at least one of the following: information of the destination node (e.g., IP), information of the destination path (e.g., designated or set path information, e.g., a path including only the IP of the destination node, and the IP of the intermediate node being virtual information).
Optionally, the routing message table may further include: resource information, the resource information comprising at least one of: available computing power resource information, 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. The destination IPs in the routing message table are ordered according to a preset rule, wherein the preset rule includes any one of the following: the order of computing power or network information from good to bad, and the order of user preference from high to low. In this way, the established transmission path can be made to more meet the needs of the user, so that the service can be scheduled to the optimal destination service node through the optimal path.
Step 102, receiving a service request of a user.
Wherein, the service request of the user (or called client) comprises the service requirement, the service ID and the like. Wherein the business requirements include computing power requirements, time delay, bandwidth and the like.
And 103, generating a forwarding table for the service Flow based on the Flow ID (service Flow identification) according to the service request and the routing message table.
When a service request arrives at the network device, the network device addresses based on the 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 path messages according to network policies. The network device may then select IP, SRV6, GRE (Generic Routing Encapsulation ), etc. 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 for the service Flow based on the Flow ID may be generated according to the destination service node. The network device may then also generate a send packet carrying the source IP, the IP of the destination service node, and the payload information (payload).
Specifically, in this step, a destination service node may be determined according to the service requirement and the routing message table, and a transmission path may be selected according to the destination service node and a preset policy, so as to generate a forwarding table for the service Flow based on the Flow ID. The network device may then also generate a send packet carrying the source IP, the IP of the destination service node, the SRH (Segment Routing Header ), and the payload information (payload).
In the embodiment of the invention, a service Flow-oriented forwarding table based on a service Flow identification (Flow ID) is generated according to the routing message table and the service request of the user so as to forward data, thereby being capable of transmitting through an optimal network path and providing an end-to-end optimal network and a computing service.
Referring to fig. 2, fig. 2 is a flowchart of a data transmission processing method applied to a network device according to an embodiment of the present invention. The network device may refer to a first-hop network device in a transmission path, such as a gateway, a router, and the like. As shown in fig. 2, the method comprises the following steps:
step 201, obtaining a service-oriented routing message table, where the routing message table at least includes service information and routing 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. The destination IPs in the routing message table are ordered according to a preset rule, wherein the preset rule includes any one of the following: the order of computing power and network information from good to bad, and the order of user preference from high to low. In this way, the established transmission path can be made to more meet the needs of the user, so that the service can be scheduled to the optimal destination service node through the optimal path.
Step 202, updating the routing message table according to the path updating reference information.
In this step, the network device may dynamically update the routing message table according to path update reference information, such as a control plane or a resource status measured by an in-band OAM (Operation Administration and Maintenance ) carried by the path.
Specifically, the update may be performed by:
in the first way, the destination IP is updated with unchanged network routes. In this manner, at least one path to a destination service node is acquired based on the network resource status and the routing message table is updated with the at least one path. In a specific application, the network device can select different network paths to reach the best destination IP service node according to the network resource status in real time, for example, using SR-policy (Segment Routing policy ) to perform multipath sharing.
In the second way, the network route of the destination IP update is updated. 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 thereafter updates the routing message table based on 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 the current power service is difficult to support, the network equipment reselects the best service node according to the latest resource information, and updates the destination service node and the network path, thereby realizing the update of the end-to-end path.
Referring to fig. 3, fig. 3 is a flowchart of a method for establishing a computing power aware path and data transmission according to an embodiment of the present invention. In the embodiment of the invention, the network equipment (such as the computing network equipment or the node) generates a routing message table based on the service ID according to the service distribution, the network resource, the computing resource and other information advertisements, wherein the routing message table comprises the service ID and the destination IP. The order of the destination IP can be arranged according to the order of computing power and network information from good to bad or according to rules such as user preference service IP. Thereafter, a route may be established based on either the IPv6 or SRV6 routing protocols.
In the embodiment shown in fig. 3, a method for establishing a power-aware path based on the IPv6 protocol and a data transmission method 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 a source IP, a flow ID, a service requirement, and a destination address IP as a 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 the service requirement, and generates a Flow ID-based forwarding table for the service Flow.
In step 303, the first hop network device R1 generates a transmission packet, which carries a source IP, a destination IP (destination service node IP of a destination service ID with optimal resource selected by the network device), and a payload information payload.
Referring to fig. 4, fig. 4 is a flowchart of a method for establishing a computing power aware path and data transmission according to an embodiment of the present invention. In the embodiment of the invention, the network equipment (such as the computing network equipment or the node) generates a routing message table based on the service ID according to the service distribution, the network resource, the computing resource and other information advertisements, wherein the routing message table comprises the service ID and the destination IP. The order of the destination IP can be arranged according to the order of computing power and network information from good to bad or according to rules such as user preference service IP. Thereafter, a route may be established based on either the IPv6 or SRV6 routing protocols.
In this embodiment, a service ID-based routing message table and a Flow ID-based traffic-oriented forwarding table are generated and maintained at the network device ingress R1, where the routing information may be path information of low latency or high bandwidth generated according to user requirements and using SR-policy, etc.
In the embodiment of fig. 4, a method of establishing a power-aware path and a manner of data transmission based on the SRv 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:
in step 401, the user sends a service request carrying a source IP, a flow ID, a service requirement, and a destination address IP as a 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 the service requirement, and at the same time, selects a transmission path according to a policy, and generates a Flow ID-based forwarding table for the service Flow.
In step 403, the first hop network device R1 generates a transmission packet, which carries a source IP, a destination IP (destination service node IP of a destination service ID with optimal network device selection resources), an SRH (path information is written into the SRH to carry), and a payload.
In a specific application, for a long link service, the network device can 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 update can be performed according to BGP (Border Gateway Protocol )/IGP (Interior Gateway Protocol, interior gateway protocol) computing power and network topology information, or according to resource information of OAM carrying in-band with the path.
Destination IP is unchanged, network route update: the ingress gateway (R1) may select different network paths to reach the best destination IP service node in real time according to the network resource status. Such as multipath sharing using SR-poll. For example, when R1 receives service data carrying a service ID, it may select a more optimal network path12 according to the latest service ID routing message table, and schedule the service to an optimal path for network transmission under the condition that the destination IP1 is unchanged.
Destination IP update, network route update: if the best service IP fails or the current computing power service is difficult to support, the ingress gateway also reselects the best service node according to the latest resource information, and updates the destination service node and the network path, thereby realizing the updating of 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 the destination service node IP2 and the updated network Path21 according to the requirements, and schedule the service to the latest Path for network transmission.
As can be seen from the above description, the following effects can be achieved by the embodiments of the present invention:
1. the client side adjusts the network transmission path and the destination service node in real time according to the network computing state through service ID addressing, and generates and maintains a routing forwarding table based on the service ID, so that transmission through the optimal network path is realized, and the end-to-end optimal network and computing power service are provided.
2. On the basis of determining the destination service node, the network side can dynamically adjust the network path according to the network computing resource condition, and the best destination service node can be addressed through the optimal path, so that the service quality is ensured, and the network efficiency of an operator is improved.
3. In case of failure or incapacity of meeting service requirements during a session, a destination service node can actively sense through a network layer to inform an application layer to switch to other service nodes without waiting for TCP (Transmission Control Protocol ) to timeout, so that service switching can be realized rapidly, and optimal user experience is ensured.
