Traffic Behavior Driven Dynamic Zoning for Distributed Traffic Engineering in SDN

摘要

System and method embodiments are provided for traffic behavior driven dynamic zoning for distributed traffic engineering (TE) in software defined networking (SDN). In an embodiment, a method in a network component for dynamic zoning for TE in SDN includes receiving at the network component network information from at least one SDN controller from a plurality of SDN controllers in a network; determining with the network component a plurality of TE zones for the network, selecting a local zone TE controller for each of the plurality of TE zones, and selecting a master TE controller according to the network information and a zoning scheme, wherein the local zone TE controller and the master TE controller are selected form one of the SDN controllers; and transmitting with the network component an indication of the local zone TE controllers, zone membership, and the master controllers to at least some of the SDN controllers.

1. A method in a network component for dynamic zoning for traffic engineering (TE) in software defined networking (SDN), the method comprising:
receiving, at the network component, network information from at least one SDN controller from a plurality of SDN controllers in a network; determining with the network component, according to the network information and a zoning scheme, a plurality of TE zones for the network, selecting a local zone TE controller for each of the plurality of TE zones, and at least one of determining zone membership of each of the TE zones and selecting a master TE controller, wherein the local zone TE controller is selected form one of the SDN controllers, and wherein the master TE controller is selected from one of the SDN controllers; and transmitting with the network component an indication of at least one of the local zone TE controllers, and at least one of at least a partial list of the zone membership of at least one of the TE zones and the master controller to at least one of the SDN controllers.
