SIP is ASCII-based, resembling HTTP, and reuses...
IP Multimedia Subsystem (IMS) is considered as the core technology of Next Generation Network, the wide use of Peer-to-peer (P2P) technology in Internet promoted the research of combination of IMS and P2P, this paper proposes a P2P file-sharing system based on IMS. The issues to be considered include the combination of P2P and SIP (Session Initiation Protocol), NAT (Network Address Translators) and...
Peer-to-peer mechanisms are considered as one of the key innovative and user-friendly solutions for real-time Internet communication services. Eliminating server-based architecture, reducing or eliminating configuration effort, and allowing end-user devices to bring resources into the network, will reshape the network as we currently know it. This presents substantial opportunities for networks and...
Peer-to-Peer systems (P2P) are getting increasingly popular as an efficient way of sharing any kind of data, and they are wide accepted in world of computing. In world of small devices (e.g. Smartphones, PDAs) P2P systems are not widespread yet, due to limitation when considering mobile device connection requirements. However, P2P system could decrease usage of bandwidth for group of users who are...
