摘要：
The disclosure provides a method for implementing an optical label, including that: an optical network is domain-partitioned according to Reconfigurable Optical Add-Drop Multiplexer (ROADM) nodes, and one or more frequencies of label signal are allocated for each domain; in each domain, an allocated frequency of label signal is circulated among ROADM nodes and/or among carriers within an ROADM node according to a preset time-division rule; a label signal is sent on a carrier or an optical channel using a circulated frequency of label signal. The disclosure further provides a system for implementing optical label. With the solution of the disclosure, label-signal transmission may be implemented on more carriers or optical channels with less frequencies of label signal, thereby not only reducing demand of the system for the number of label frequencies, but also facilitate label-signal extraction.
摘要（中）：
本发明提供了一种实现光标签的方法，包括：根据可重构光分插复用器（ROADM）节点对光网络进行域划分，并为每个域分配一个或多个频率的标签信号; 在每个域中，根据预设的时分规则，分配的标签信号的频率在ROADM节点之间和/或ROADM节点内的载波之间流通; 使用标签信号的循环频率在载波或光信道上发送标签信号。 本发明还提供了一种实现光学标签的系统。 采用本发明的方案，标签信号传输可以在标签信号频率较低的更多载波或光通道上实现，不仅减少了系统对标签频率数量的需求，而且便于标签信号提取。
