SERVICE PATH ALLOCATION METHOD, ROUTER AND SERVICE EXECUTION ENTITY

摘要

Embodiments of the present invention provide a service path allocation method, a router, and a service execution entity. In the method provided in the embodiments, a router obtains a user identifier and IP 5-tuple information after receiving a packet, queries for a corresponding target service processing path according to the user identifier and the IP 5-tuple information, and, after encapsulating the service packet, sends the service packet to the first-hop service execution entity in the service path for corresponding service processing. For a different service flow, the executed target service processing path is different. In the method provided in the embodiments, different service paths can be allocated to different service flows according to a user's customization and a service type, thereby implementing dynamic allocation of the service paths and increasing a utilization ratio of network resources.
