On programming an MP-TCP analyzer plugin using OpenDayLight Beryllium as the SDN controller

Abstract:

MP-TCP (MultiPath-TCP) is a protocol that sends data through multiple paths in hosts that have several network interfaces by creating a set of TCP (Transmission Control Protocol) connections. We propose using the principles of SDN (Software Defined Networking) for monitoring and analyzing traffic in a network. For implementing a concrete tool based on this idea, the key principles of the proposed solution must first be fully understood so they are described along with the programming aspects of the development of a plugin for analyzing MP-TCP messages using OpenDayLight (ODL) Beryllium as the SDN controller. The ODL's architecture and services used in the plugin implementation are also presented. ODL services are used trough their available API for developing our plugin. The MP-TCP plugin must generate both proactive and reactive rules that should be installed in the network devices so that MP-TCP messages are sent to the controller for processing and displaying to the network administrator. Results of tests obtained with the Analyzer when using physical and virtual switches in a linear topology are presented.
