碩士 === 國立交通大學 === 電機資訊國際學程 === 104 === Software-Defined Networking (SDN) has set up the base of a new networking infrastructure to solve many of current obstacles and limitations which current networks have. Within few years SDN has gained popularity in the industry and academia. Change in networking infrastructure in the form of SDN has opened up the research areas in this tightly integrated field. Software Defined Networks (SDN) enabled multi-domain networks are core of heterogeneous and wide area networks. The SDN technology is going to be implemented in datacenter networks, mobile networks and enterprise networks. Such networks are demanding and requires independent and private control plane and thus these networks much be resilient, scalable and expandable. In this thesis DMC, a Distributed approach in Multi domain Controllers that is able to cope wide area networks while preserving the privacy of their domains. It also deals with the link failure across the domains making it resilient in terms of link failure. Controller manages their own network domain and exchanges only necessary information with other controllers to entertain end to end services. East West interface is defined between the controllers that is achieved by a very light weight control channel and is using RabbitMQ as its messaging model. It also helps to reduce the extra overhead since only necessary information is exchanged between the domains. That information is stored in the centralized database present in each domain where other modules retrieve/enrich information from database according to their requirement. Our application is implemented on top of RYU control platform and to best of our knowledge this is the first distributed application designed on RYU control platform.
