Title: A Framework for OpenFlow-like Policy-based Routing in Hybrid Software Defined Networks
Author(s): Anshuman Mishra, Deven Bansod, Kotakula Haribabu
Keywords: Software Defined Networks, Hybrid SDN, Policy Framework, Legacy Devices, OpenFlow
Abstract: Software Defined Networks (SDNs) provide a centralized view of the network and allow extensive programmability. They separate the control and data plane opening up immense scope in developing low cost control and management applications to operate the network. Yet, network administrators are ambivalent to revamp their entire network hardware to bring in SDN-compatible switches. This leads to the need for developing models for gradual adaptation of SDN technology. In this paper, we present a framework which allows for policy implementations based on all OpenFlow 1.4 specified match fields, in legacy Layer 3 devices. This enables the legacy network to reap the benefits
of SDN in an incremental, controlled and consistent manner.
