Abstract
A method is executed by a controller in a software defined network to conserve bandwidth over the software defined networking (SDN) network by compressing Internet protocol (IP) headers of data packets traversing the SDN network. The IP headers of the data packets remain compressed as the data packets traverse the SDN network. The ingress switch is an entry point for the data packets as the data packets traverse the SDN network. The egress switch is an exit point for the data packets as the data packets traverse the SDN network. The method includes configuring a flow table of the ingress switch to forward the data packets to a header compressor module in the ingress switch, configuring the ingress switch to instantiate the header compressor module, and configuring a group table of the ingress switch to manage forwarding of the data packets toward the egress switch.
