摘要:

本文提出一种在无线信道上利用MPLS的标签转发原理建立双向的虚电路的方案。为适应无线的特点,本文对MPLS的相关内容作了一些改动。当建立起虚电路以后每个节点就利用建立好的标签转发表(FTN)转发进入本网的IP数据报。

A Scheme for the Establishment of Bidirectional MPLS Virtual Circuit in Wireless Network

()

Abstract:

A strategy to establish a bidirectional MPLS virtual circuit through wireless network is proposed.Some content of MPLS is modified to suit the wireless network characters such as the narrower bandwidth, higher probability of bit error, time-varying and dynamic topology. The strategy has low latency and dynamic ability. After establishing the virtual circuit, messages can be forwarded with labels instead of packet head, so packet overhead will be reduced, thus increasing bandwidth efficiency.
