ＭＰＬＳ的原理和技术概要ＭＰＬＳ的核心机制包括：①赋予数据流的标签的语义；②转发机制，包括基于标签插片（Ｌａｂｅｌｓｈｉｍ）或标签化的ＡＴＭ－ＶＰＷＣＩ和ＦｒａｍｅＲｅｌａｙ－ＤＬＣＩ的转发机制；③标签分配机制。在分析ＭＰＬＳ基本原理之前，除了网络常用语
MPLS Principles and Techniques MPLS core mechanisms include: (1) the semantics of the labels given to the data stream; (2) forwarding mechanisms, including forwarding mechanisms based on Labelshim or tagged ATM-VPWCI and FrameRelay-DLCI; Distribution mechanism. Before analyzing the basic MPLS principles, in addition to common language network
