METHOD, SYSTEM, AND CONTROLLER FOR ROUTING FORWARDING

摘要

Provided in the present invention are a method and system for routing forwarding. The method comprises: a controller issues a pre-generated routing flow table respectively to an eNB and to an AGW; and, the eNB and the AGW respectively distribute data on the basis of the routing flow table received. Also provided in the present invention is the controller. With the controller transmitting the routing flow table to the eNB and to the AGW, the present invention allows for application of the extended OpenFlow protocol in an EPS, reduces costs for network upgrade, simplifies network upgrade, and shortens network upgrade cycle.
