Abstract: An apparatus and method for processing a packet in a multi-protocol label switching-transport profile (MPLS-TP) network are provided. In the method of processing a packet, a packet transport layer (PTL) index and a layer stack (LS) or multiple label pop (MPOP) loopback header are used, and it is possible to remove a size limitation on lookup results of a lookup table when multiple labels are stacked, and solve the problem of having to extract all labels as label keys regardless of label operations upon an incoming label map (ILM) table lookup.
Abstract translation: 提供了一种在多协议标签交换传输模式（MPLS-TP）网络中处理分组的装置和方法。 在处理分组的方法中，使用分组传输层（PTL）索引和层堆栈（LS）或多标签弹出（MPOP）环回报头，并且可以消除查找查找结果的大小限制 当多个标签堆叠时，可以解决不必将所有标签提取为标签键的问题，无论标签操作如何，都可以在进入的标签映射（ILM）表查找中进行。

Abstract: In order to perform protection switching of a frame that is transmitted and received between a packet processor and a host processor, when an input frame is a receiving frame and a signal failure has occurred, by transporting a message including a protection switching command to a packet processor, protection switching is performed. Information representing that protection switching is performed is recorded in a header of the receiving frame, and a frame including a message including a corresponding header is transported to the host processor.
Abstract translation: 为了执行在分组处理器和主处理器之间发送和接收的帧的保护切换，当输入帧是接收帧并且发生信号故障时，通过将包括保护切换命令的消息传送到分组 处理器，执行保护切换。 执行保护切换的信息被记录在接收帧的报头中，并且将包括对应报头的消息的帧传送到主处理器。
