异步转移模式(ATM)网络的业务类型及流量控制

Study on service type and traffic controlling of asynchronous transfer mode network

阐述了异步传输模式的基本原理.对ATM的业务类型及流量控制技术进行了探讨,对比分析了CBR、RT-VBR、NRT-VBR、ABR、UBR 5种业务类型的特点及其处理方式,探讨了CAC、UPC等流量控制技术及其适用场合.给出了PVC的流量参数配置及其测试方法,讨论了ATM技术的优点及其局限性,对实际工程组网有借鉴意义.

The principle of the asynchronous transfer mode is described, ATM adopts the strategy of statistically multiplexing, connection oriented, and QoS supporting. The service type and traffic controlling of ATM is studied, the characteristic and processing method of CBR, RT -VBR, NRT -VBR, ABR, UBR service type, and the traffic controlling technology such as CAC, UPC is discussed. This paper presents the configuration and testing method of PVC traffic parameter, and discusses the advantage and limitation of the ATM technology, it can be a reference for the construction of the practical network.
