Because ss7 has more intelligent capabilities than user - network interface protocols such as isdn primary rate interface , ss7 can help ease congestion across the internet 由于七号信令比诸如isdn的基础速率接口等用户网络接口协议更具智能功能,所以七号信令有助减轻因特网上的拥挤。
This thesis introduces the application of atm technology in the special b - isdn and the atm protocol architecture . it also briefly describes the atm user - network interface protocol q . 2931 and the network - network interface protocol pnni . based on these knowledge , this thesis does certain research and simulation on the atm signaling and routing technology 本文首先介绍了atm技术的特点和在专用b - isdn中的应用,然后介绍了atm协议结构尤其是控制面信令协议:用户-网络接口协议q . 2931和网络-网络接口协议pnni ,并在此基础之上对atm信令和路由技术进行了研究和仿真。
