The main design principle of Information-Centric Networking (ICN) is the name based routing, that makes users able to ask for a data object by only using its name, and makes the network deliver data to users from a nearby cache if in-network caching is available. Software-Defined Networking (SDN) decouples the control layer from the data layer, so that the complexity, and network control and management...
In this paper, we present evaluation results of Service Function Chaining implementation scheme using multiple flow tables of OpenFlow. With a single flow table in the implementation, the number of flow entries in the flow table significantly increases as the number of service chains increases. This results in looking up larger flow table and higher processing time in processing packets. We have addressed...
In the last couple of years Software Defined Network (SDN) have come into existence which empowers network operators with more flexibility to manage and program their network. This type of network solves the limitation of legacy networks. Data plane and control planes are separated from each other as a result data plane devices simple act as a packet forwarding device and leaving the decision making...
The IP Multimedia Subsystem (IMS) is a kind of Multimedia business form and it is an architectural framework for delivering IP multimedia services. In order to increase flexibility and reliability, in this paper we propose a different perspective which maintains the existing IP Multimedia Subsystem (IMS) based signaling platform while processing flow via distributed SDN controllers. Software Define...
Software Defined Networking, SDN, is the programmable separation of control and forwarding elements of networking that enables software control of network forwarding that can be logically and/or physically separated from physical switches and routers. The following important question is considered in this paper: to what extent can SDN-based networks address network security management problems? The...
