Switch routing table utilizing software defined network (SDN) controller programmed route segregation and prioritization

摘要

In one embodiment, a system includes a network having a plurality of switches and one or more devices connected to one or more of the plurality of switches, a software defined network (SDN) controller connected to one or more of the plurality of switches in the network, the SDN controller having logic integrated with and/or executable by a processor, the logic being adapted to determine SDN routes through the network between the one or more devices and each of the plurality of switches and send one or more SDN routes to each switch in the network capable of communicating with the SDN controller. In other embodiments, methods and computer program products are also described for providing SDN routes through a network.

1. A system, comprising:
a network, comprising:
a plurality of switches; andone or more devices connected to one or more of the plurality of switches; a software defined network (SDN) controller connected to one or more of the plurality of switches in the network, the SDN controller comprising logic integrated with and/or executable by a processor, the logic being configured to:
determine SDN routes through the network between the one or more devices and each of the plurality of switches;send one or more SDN routes to each switch in the network capable of communicating with the SDN controller; andmodify a routing information base (RIB) in each switch in the network capable of communicating with the SDN controller to alter a priority ordering of routes stored therein, the routes stored therein comprising the SDN routes sent to each switch in the network capable of communicating with the SDN controller and traditional routes, the traditional routes being routes learned by each switch, routes configured by an administrator, or a combination thereof,wherein the one or more SDN routes are indicated as being of a type different from the traditional routes stored by the plurality of switches.
