NSIS Extensions: An End-to-End QoS Aware Signaling Protocol for NGN

Tahir Mehmood and Sathiamoorthy Manoharan

Abstract—The Next generation network (NGN) deployment is in its infancy. With great technological advancement in internetworking infrastructure, NGN faces many challenges in the form of heterogeneity in networking and user expectations such as higher bandwidth, seamless mobility, internetworking protocols, multicast addressing (or multicasting), security and a guaranteed Quality of Service (QoS). This paper investigates the major challenges being faced during the transition of current internetwork into the future generation network i.e. NGN. We will look into IETF’s efforts on developing signaling protocols in satisfying the ever demanding end-toend guaranteed QoS needs by end users or interconnected network nodes. A comparative study is done for Integrated Services (IntServ), Differentiated Services (DiffServ), Resource Reservation Protocol (RSVP), and the newly developed Next Steps in Signaling (NSIS) as QoS signaling protocol and NSIS possible extensions.

Index Terms—QoS, NGN, RSVP, NSIS, QoS NSLP.
