ROUTE DISTRIBUTING METHOD, SYSTEM AND CONTROLLER

摘要

A route distributing method, system and controller. The method is used in a BGP-based route network. A physical controller in the route network is connected to a plurality of physical routers separately. The method comprises: the physical controller receives route information reported by at least one of the plurality of physical routers; a traffic path is obtained with the physical router as an egress router for transmitting traffic to a target router; a route is generated for the physical routers in the traffic path; and the generated route is sent to the corresponding physical routers. In the present invention, the traffic transmitted to the same target address is prevent from jamming at the egress router, and the router receiving the traffic can directly generate a route for the traffic according to the traffic path to transmit the traffic to the next router without recalculation, so that the performance of the route network is improved.
