摘要:

介绍了新型多播技术位—索引显式复制(bit indexed explicit replication,BIER)的原理与优势,并将其与传统多播技术进行对比分析,指出BIER技术是未来网络演进的重要选择。同时通过原型系统的介绍,详细分析BIER的可实施性、现网演进能力等。并相信在SDN演进趋势下,BIER技术是可控多播的必然选择。

关键词: 多播, 按位显示复制转发, 原型

Abstract:

The principle and advantages of BIER were introduced,and it was compared with traditional multicast technology.It was pointed out that BIER technology was an important choice for future network evolution.At the same time,through the introduction of the prototype system,the feasibility of the BIER and the evolution capability were analyzed in detail.It was predicted that BIER technology was an inevitable choice of controllable multicast under the trend of SDN evolution.

Key words: multicast, BIER, prototype
