The use of Software Defined Network (SDN) in recently networking architecture has brought tremendous advantage in computer networking technology. Administrative issues such as routing, security and load balancing can be centralized and automated in SDN controllers. Controllers have been an integral part of the SDN architecture enabling intelligent networking. However, because all the packets are transmitted...
Software-defined networks (SDNs) detach the forwarding plane from the control plane and communicate instruction sets between the separated planes via the OpenFlow protocol. This arrangement solves some current challenges. However, it introduces challenges of its own that cut across security, scalability and lack of well-defined standards for northbound Application Programming Interfaces (API). This...
Enterprise networks have become increasingly important with the rising number of users accessing their services, which consequently brings challenges in various aspects. Though Open Flow, the promising scheme for enterprise network control, can provide fine-grained and flow-level control in networks, yet it still has a few undesirable designs in security, scalability and performance. Inspired by many...
