Paradoxically, with an ever-increasing traffic demand, today transport-network operators experience a progressive erosion of their margins. The alarms of change are set, and software define networking (SDN) is coming to the rescue with the promise of reducing capital expenditures and operational expenses. Driven by economic needs and network innovation facilities, today transport SDN (T-SDN) is a...
This work demonstrates a hierarchical control plane architecture for Software Defined Networking (SDN)-based Segment Routing (SR) in multi-domain networks. An orchestrator application, on top of multiple open source SDN controllers, creates a hierarchical control plane architecture using northbound RESTFul APIs of controllers. The orchestrator has control, visibility and traffic engineering capabilities...
Multipath TCP is an extension to TCP protocol that allows a single connection to be split across multiple paths. MPTCP overcomes few limitations of TCP thereby offering added benefits like increased throughput and network resource utilization and resilience to possible link failures. Different data paths over the network face different end-to-end path delay. The performance of MPTCP is affected not...
