Service-oriented router simulation module implementation in ns2 simulator

Abstract

The Service-oriented Router (SoR) is a router for next generation networks. This router has a high-throughput database and it has the capability to snoop all transaction in its interfaces. The SoR also provides an API which can provide stored content in order to enrich services. The SoR has the potential to shift the current Internet infrastructure to an information-based, open innovation platform. In order to evaluate the efficiency of SoR-based applications and services, a specific simulator is required. Though the NS2 simulator does not simulate payload handling, it is a well-known network simulator and there are many resources available for evaluations. In this research, we implemented three new modules for the NS2 platform to test the concepts of an SoR, an SoR agent, a packet container and a packet analyzer. The SoR agent can interconnect the application and physical layers of the NS2 module with an additional function that can handle user data as a real payload and attaches it to the IP packet. The packet container is an improved NS2 module that can attach user data and trace information. A successful simulation has been performed for end-to-end packet transfer with a 0.02s packet delivery delay compared to typical NS2 packet delivery. The NS2 router has been enhanced for packet stream analyzing and content centric packet re-routing. Content centric packet re-routing has been achieved with 0.01s additional delay for end-to-end packet delivery. Result shows that Deep Packet Inspection and content centric networking in an SoR-based network can be achieved.
