Abstract: A method of fault notification in a carrier Ethernet having the capability of generating and transmitting OAM packets having flag fields, comprises inserting a bit in one of the flag fields to indicate the presence of service-affecting information in the OAM packets, detecting the presence of the inserted bit at the end of a data path, and performing a service protection action in response to the detection of the inserted bit prior to parsing the information in the message. One type of service protection action is protection switching.

Abstract: A method for managing data packets passing through an Ethernet node having multiple ingress ports and multiple egress ports, the ingress ports receiving the data packets from at least one service, and the egress ports configured with at least one Logical Transport Resource (LTR) configured as a predefined path between one of the egress ports and a destination in the Ethernet network. The method comprises mapping one or more of the services to each of the at least one LTR, shaping each of the at least one LTR to a configured rate, and transmitting data packets to the Ethernet network via the egress ports.
Abstract translation: 一种用于管理通过具有多个入口端口和多个出口端口的以太网节点的数据分组的方法，所述入口端口接收来自至少一个服务的数据分组，以及配置有至少一个逻辑传输资源（LTR）的出口端口，所述逻辑传输资源（LTR）被配置为 一个出口端口和以太网网络中的目的地之间的预定义路径。 该方法包括将一个或多个服务映射到至少一个LTR中的每一个，将至少一个LTR中的每一个映射到配置的速率，以及经由出口端口将数据分组发送到以太网。
