Abstract: A protection switching method for a link aggregation group and an apparatus thereof are provided to perform the protection switching independently for respective VLANs(Virtual Local Area Networks) by generating an OAM frame according to a G.8031 standard. A protection switching apparatus includes an LAG(Link Aggregation Group) distribution path information extractor(223) and an OAM(Operations, Administration and Maintenance) frame header generator(224). The LAG distribution path information extractor determines the physical port for a working LAG or a protection LAG from plural physical ports, to which an Ethernet frame from a MAC(Media Access Control) client is distributed. The OAM frame header generator generates a header of the OAM frame, which is related to the Ethernet frame based on the extracted path information. A protection switching scheme according to a G-8031 standard is allocated to the LAG. The OAM frame and the Ethernet frame are distributed to the same physical ports of the working or protection LAG for respective VLANs.
Abstract translation: 提供了一种链路聚合组的保护倒换方法及其装置，通过根据G.8031标准生成OAM帧，对各个VLAN（虚拟局域网）进行独立的保护切换。 保护交换装置包括LAG（链路聚合组）分配路径信息提取器（223）和OAM（操作，管理和维护）帧头生成器（224）。 LAG分发路径信息提取器从多个物理端口确定来自MAC（媒体访问控制）客户端的以太网帧分发的工作LAG或保护LAG的物理端口。 OAM帧头生成器基于提取的路径信息生成与以太网帧相关的OAM帧的报头。 根据G-8031标准的保护倒换方案分配给LAG。 OAM帧和以太网帧分配到相应VLAN的工作或保护LAG的相同物理端口。
