Abstract
This document details all the information needed to understand and test distributed mobility management using the SDN paradigm. This project stars by an analysis of the mobility problem in dense networks. Traditionally mobility has been managed with hierarchical approaches extending the current mobility protocols. But thinking in the future evolution of the network into dense environments some scalability problems appear. The traditional centralized elements may not be able to handle all the traffic in the network and bottlenecks appear at the Mobility Anchors. Nowadays, the problems related to scalability are mostly resolved with hardware upgrades, but in dense environments this couldn’t be enough and surely it would be quite expensive. To find a solution to this problem the IETF has chartered the Distributed Mobility Management (DMM) Group.This project focus on implementing a DMM-based mobility solution designed within the EU FP7 CROWD project.
Once the analysis of the problem ended and the requirements of the theoretical solution were defined, we developed all the necessary elements to physically build a distributed network using SDN to manage layer 2 and layer 3.The entities of the network are defined by the CROWD projectin its related publications[9][10]. These districts were run using an SDN implementation called OpenFlow. With all the elements developed we proceed to perform the necessary tests in order to evaluate the distributed mobility management as a solution. This document explains the full design, execution and validationprocesses. Finally all the measurements and statistical data are detailed in order to have an approximation of the services that could achieve the developed network.
