Abstract: A service routing method and apparatus may resolve a current problem of large costs of a CFN router. The method includes: a first routing node receives a first packet, where the first packet carries service identifier information and first service node address information; and forwards the first packet based on the first service node address information. The service identifier information is used to indicate an identifier of a first service provided by at least two service nodes including a first service node, and the first service node address information is used to indicate an address of the first service node.

Abstract: A method includes receiving, by a network node, a first data packet from a client, wherein the first data packet includes an identifier of a service. The method further includes obtaining, by the network node, flow affinity attribute information of the service based on the identifier of the service, wherein the flow affinity attribute information of the service includes a flow affinity type of the service and a flow affinity timeout time of the service. The method further includes establishing, by the network node, a flow entry based on the flow affinity attribute information of the service in response to the first data packet being a 1st data packet in a data flow, wherein the flow entry is useable to forward a subsequent data packet in the data flow.

Abstract: Examples in this disclosure relates to methods and apparatus for routing data packet. One example method includes receiving a data packet, determining a first computation task type corresponding to the data packet, determining, based on a pre-obtained first correspondence between the first computation task type, nodes, and a computing performance corresponding to each of the nodes, at least one of the nodes corresponding to the first computation task type and a first computing performance corresponding to the at least one of the nodes, determining a target node from the at least one of the nodes based on the first computing performance corresponding to the at least one of the nodes and a link status between a local node and each of the at least one of the nodes, determining an address of the target node as a destination address of the data packet, and forwarding the data packet based on the destination address.
