针对网络由IPv4向IPv6的过渡问题,介绍了一种演进方案——6 PE技术。阐述了该演进方案的具体情况,详细说明了该方案采用多协议标记交换技术,使得IPv6与IPv4应用能在骨干网络上共存的基本原理,并对实施该方案的可行性进行了分析。
Aiming at the problem of network transition from IPv4 to IPv6, this paper presents an evolution scheme - 6 PE technology. The specific situation of this evolution plan is expounded. The principle of using multi-protocol label switching technology in this scheme is described in detail. The basic principle that IPv6 and IPv4 applications can coexist on the backbone network is analyzed. The feasibility of implementing this scheme is also analyzed.
