Method, apparatus and system for determining service transmission path

An apparatus for determining a service transmission path, comprising:

• an interface;
• and
• a signal processor,
• wherein the interface is configured to receive a service chaining object sent by a client device based on path computation element communication protocol (PCEP) extensions and transmit the service chaining object to the signal processor, wherein the service chaining object includes service processing capacities that service nodes need to provide when transmitting a service in a network,
• wherein the signal processor is configured to obtain the service chaining object transmitted by the interface, determine 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 generate a service transmission path based on the determined service nodes, for transmitting the service initiated by the client device,
• wherein the service chaining object further includes processing priorities corresponding to the service processing capacities that the service nodes need to provide;
• and
• wherein the signal processor is configured to generate the service transmission path based on the processing priorities corresponding to the service processing capacities that the determined service nodes are capable of providing respectively.
