Abstract: TCP splicing is a mature technology for HTTP in layer 7 switching. A nother important application of layer 7 switching is streaming media. The major streaming media is based on RTP, which bases on UDP, and uses dynamic ports. So it can not be load balanced by layer 4 switches. This paper proposes a new laye r 7 technology called RTP splicing to support the RTSP application using RTP. Th e technology inproves the performance of layer 7 switch greatly. Furthermore, it gives out a prototype of layer 7 switch based on RTP splicing, and gains good p erformance result.

摘要： 针对RTSP这样的基于RTP的应用，提出了RTP粘结技术。该技术大大提升了面向流 媒体第七层交换机的性能。基于RTP粘结技术给出了一个第七层交换机的原型，同时给出了 性能测试的结果。
