Multicast backbone
1.： This paper first introduces the concepts associated with multicast backbone(Mbone)and multicast,then discusses the heterogeneity of the Internet and Mbone. Based on the above discussion,how to transmit efficiently real－time multimedia data is discussed over the heterogeneous environment. Finally,two different methods of handling the heterogeneity are compared．
4.IP/DWDM(dense wavelength division multiplexing) optical Internet is one of the mainstream networking techniques as backbone for NGI(next generation Internet), and how to improve its fault-tolerance capability and QoS multicast provision becomes critical. In this respect,the fault-tolerant QoS multicast routing is one of the effective solutions.
