In our proof-of-concept research work we make use of open-source components (like NOX) and extend them to control an access/aggregation network with a centralized controller that also interworks with a legacy distributed MPLS core network (see attached Figure 1). We show (i) unicast video stream setup as a result of interworking with the core MPLS network, including the use of OSPF and LDP, (ii) multicast video stream with dynamic subscription/unsubscription and optimal transmission tree recalculation, (iii) LLDP based controller driven restoration versus data plane managed protection. |
