— Peer-to-Peer (P2P) systems have witnessed an explosive growth in popularity due to their desirable characteristics (robustness, scalability, availability). In this paper, we present an approach to bring these characteristics into the control plane of IP networks, which mainly relies on signaling protocols such as SIP to setup multimedia and instant… (More)
Data and telephone service providers have started considering migration to an IP based environment. This paper presents an unstructured peer-to-peer approach to initiating and maintaining sessions over IP using session initiation protocol (SIP). The offered solution is completely modular and is compatible with traditional server-client based approaches… (More)
We present a novel approach to model the uplink air interface access mechanism in a CDMA network as a slotted random access system, and use it to calculate the soft blocking probability in a multiservice CDMA network. Simulation results show that our method is accurate.
