Description: SIP称为会话发起协议（Session Initiation Protocol)。SIP是Internet工程任务组（IETF）提出的建议中的一项协议，其目的是为了替代H.323的部分协议，主要是考虑到在下一代网络（NGN）中，由于IP产品和IP网关将在网络中得到大规模使用和集成，使得端到端都可以采用IP以实现纯IP的业务应用；而基于纯IP的SIP借鉴了HTTP和SMTP，结构简单并具有可扩充性和可扩展性。此外，SIP还提供良好的QoS支持。对于NGN在IP网络上实现VOIP和多媒体通信来讲，SIP在全面满足NGN特性要求的应用上具有独特的优势，必将成为下一代网络VOIP的重要解决方案。

Description: This a simulator written in Tcl to simulate a network node carrying GSM and GPRS traffics with QoS mechanisms. The payload type including circuit-switched voice, VoIP and web traffic, and the performance including packet drop, delay can be analyzed. The implemented QoS mechanism is DiffServ, with 4 RED queues for different services with different priorities.-This is a simulator written in Tcl to simulate a network node carrying GSM and GPRS traffics with QoS mechanisms.

Description: This paper discusses on quality of service (QoS) guarantee in P2P network, and
proposes a simple QoS architecture. In section 1, main characteristic of P2P network
and the importance of Qos in P2P network are viewed. In section 2, QoS requirements
of different services in P2P network are deeply discussed. In section 3, some
important techniques using for guarantee QoS of different services, such as File
Sharing, VoIP and IPTV are analyzed. In section 4, a simple generic QoS architecture
based on P2P is proposed.-This paper discusses on quality of service (QoS) guarantee in P2P network, and proposes a simple QoS architecture.
