Apply embedded openflow MPLS technology on wireless Openflow — OpenRoads

Openflow is one of the most important and popular next generation internet structure and technology. Its thought of “software decide network” makes dispatch of controller and date layer. Controller uses the openflow protocol to communicate and control the openflow switch to generate flow table, thus to achieve the centralized control of the whole network. OpenRoads is the framework about the wireless Openflow environment. It successfully apply the thought of SDN on the wireless mobile environment. As a propose to improve the performance and quality of the OpenRoads, The new embedded Openflow-MPLS(EOF-MPLS) is presented. An important technology key point is that both traditional MPLS and Openflow support the thought of separation between controller and date layer which makes a solid foundation for the new EOF-MPLS. EOF-MPLS offered forward equal class(FEC), Label distribute Protocol(LDP) to improve the efficiency of the nodes forward. It makes tight coupling with Openflow structure and support the QoS and traffic engineering. At last an entropy is came up with to assess the communication effectiveness of the EOF-MPLS to the OpenRoads.
