METHOD, APPARATUS AND SYSTEM FOR DETERMINING SERVICE TRANSMISSION PATH
First Claim
1. A method for determining a service transmission path, comprising:
- receiving a service chaining object sent by a client device based on an expanded path computation element communication protocol (PCEP), wherein the service chaining object includes service processing capacities that service nodes need to provide when transmitting a service in a network;
determining at least one service node matched with the service chaining object in the network according to service processing capacities that service nodes in pre-stored service node attribute information are capable of providing; and
generating a service transmission path based on the determined service nodes, for transmitting the service initiated by the client device.

Abstract
The present disclosure discloses a method, an apparatus and a system for determining a service transmission path. The method includes: receiving a service chaining object sent by a client device based on an expanded path computation element communication protocol (PCEP), wherein the service chaining object includes service processing capacities that service nodes need to provide when transmitting a service in a network; determining at least one service node matched with the service chaining object in the network according to service processing capacities that service nodes in pre-stored service node attribute information are capable of providing; and generating a service transmission path based on the determined service nodes, for transmitting the service initiated by the client device. The problems of large flow pressure and low utilization rate of the service nodes deployed in the network may be well solved.
