Description: 会话初始协议SIP 作为推荐的Internet 会议和VoIP 应用层信令控制协议,在RFC 中没有严格地给出其行为的
形式化模型。介绍了SIP 协议,简要阐述了SDL(specification and description language) 的基本概念及使用它描述网络协议的优
点,并利用SDL 给出了SIP 协议的形式化描述,为进一步的协议实现和验证奠定了基础。-SIP Session Initiation Protocol, as recommended by Internet meetings and VoIP application layer control protocol signaling, in the RFC is not strictly given formal model of his actions. Introduced the SIP agreement, briefly expounded on SDL (specification and description language) the basic concept and use it to describe the advantages of network protocols and to make use of SDL is given formal description SIP agreement, in order to further the achievement of the agreement laid the foundation and validation .

Description: 广域网质量监控软件，VoIP Monitor 模块帮助您测定与跟踪最需要关注的广域网语音质量性能。-VoIPmonitor is open source network packet sniffer with commercial frontend for SIP SKINNY RTP and RTCP VoIP protocols running on linux. VoIPmonitor is designed to analyze quality of VoIP call based on network parameters- delay variation and packet loss according to ITU-T G.107 E-model which predicts quality on MOS scale. Calls with all relevant statistics are saved to MySQL or ODBC database. Optionally each call can be saved to pcap file with either only SIP/SKINNY protocol or SIP/RTP/RTCP/T.38/udptl protocols. VoIPmonitor can also decode audio.

Description: VoIPmonitor 是一个开源的实时网络抓包并分析SIP和RTP protocol的程序. -VoIPmonitor is open source live network packet sniffer which analyze SIP
and RTP protocol. It can run as daemon or analyzes already captured pcap
files. For each detected VoIP call voipmonitor calculates statistics about
loss, burstiness, latency and predicts MOS (Meaning Opinion Score) according
to ITU-T G.107 E-model. These statistics are saved to MySQL and each
call is saved as pcap dump. Web PHP application (it is not part of open
source sniffer) filters data and graphs latency and loss
distribution. Voipmonitor also detects improperly terminated calls when
BYE or OK was not seen. To accuratly transform latency to loss packets,
voipmonitor simulates fixed and adaptive jitterbuffer.
