Default values mediator used for a wireless transport SDN Proof of Concept

Software Defined Networking (SDN) is a recent paradigm that emerged in the networking community, as a need for mitigating the limitations proven by traditional networks. It was introduced, in the beginning, in campus networks and then in data centers, but the trend is to encapsulate SDN in all the aspects of the network, from optical transport to wireless transport and even Internet exchange points. This paper presents part of the work that was done for the second Proof of Concept (PoC) of SDN for the Wireless Transport, namely the Default Values Mediator (DVM). The PoC gathered several entities, that form the Wireless Transport Project inside the Open Networking Foundation, such as microwave equipment vendors, integrators and application providers and operators, which developed and executed the PoC in order to prove the utility of a common information model to be used for management and configuration of microwave devices in the networks, in the context of SDN. The DVM is an open-source software tool, based on the OpenYuma framework, that emulated a microwave device, and was used for developing and testing the SDN applications proposed in the use cases of the PoC.
