METHOD AND APPARATUS FOR SERVICE ROUTING

摘要

Disclosed are a method and apparatus for service routing. The method comprises: selecting a specific VAS example for a user data packet to form a service link according to a service link tag of the user data packet; or selecting a specific VAS example for a user data packet to further allocate the service link tag for the user data packet; and generating, by a controller, a flow table according to the service link tag, and sending same to a switch for performing service routing on the user data packet by the switch. A service link is formed by selecting a specific VAS example for a user data packet. The problem that urgently needs to be solved by network operators currently is to realize the load balance among similar VAS examples in a VAS pool.
