摘要： In one embodiment, a method associated with a multiple I-service registration protocol (MIRP) includes receiving into an 802.1ah I-component an MVRP TCN from an 802.1ad component. The TCN may be received, for example, from an 802.1ad bridge. The TCN may identify an affected service using an S-VID. Therefore, the example method may include identifying the S-VID specified by the TCN. The method may also include identifying I-SIDs related to the S-VID. The I-SIDs may be identified by consulting an S-VID to I-SID translation table associated with the 802.1ah I-component. The method may also include providing an 802.1ah MIRP PDU to another 802.1ah component. The MIRP PDU may be based on the MVRP TCN and on the I-SID.
摘要翻译：在一个实施例中，与多个I服务注册协议（MIRP）相关联的方法包括从802.1ad组件向802.1ah I组件接收MVRP TCN。 TCN可以例如从802.1ad桥接收。 TCN可以使用S-VID来识别受影响的服务。因此，示例性方法可以包括识别由TCN指定的S-VID。该方法还可以包括识别与S-VID相关的I-SID。可以通过咨询与802.1ah I组件相关联的S-VID到I-SID转换表来识别I-SID。该方法还可以包括向另一个802.1ah组件提供802.1ah MIRP PDU。 MIRP PDU可以基于MVRP TCN和I-SID。

摘要： Apparatus and method of detecting a fault in a network service includes an Ethernet access network domain in which a heartbeat message is broadcast at a periodic interval by each of a plurality of edge devices associated with an instance of the network service. Each of the edge devices also receives the heartbeat messages broadcast at the periodic interval from other edge devices. A fault occurrence is identified when the edge device fails to receive an expected heartbeat message at the periodic interval from one of the other edge devices.

摘要： A broadband access node includes a port for connection with a Digital Subscriber Line and a processor to run code that implements a virtual maintenance end point (vMEP). The vMEP translates an IEEE 802.1ag Loopback Message (LBM) received from a device on an Ethernet access network into a legacy operations and maintenance (OAM) message that is transmitted to a residential gateway (RG) device. The legacy OAM message determines a link-level connectivity status between broadband access node and the RG device. The vMEP also transmits a reply message back to the device on an Ethernet access network in compliance with the IEEE 802.1ag specification. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
摘要翻译：宽带接入节点包括用于与数字用户线路连接的端口和用于运行实现虚拟维护终点（vMEP）的代码的处理器。 vMEP将从以太网接入网络上的设备接收的IEEE 802.1ag环回消息（LBM）转换为传输到住宅网关（RG）设备的传统操作和维护（OAM）消息。传统的OAM消息确定宽带接入节点和RG设备之间的链路级连接状态。 vMEP还根据IEEE 802.1ag规范在以太网接入网络上将回复消息发送回设备。要强调的是，该摘要被提供以符合要求抽象的规则，允许搜索者或其他读者快速确定技术公开内容的主题。提交它的理解是，它不会用于解释或限制权利要求的范围或含义。 37 CFR 1.72（b）。

摘要： In one embodiment, a wireless access point receives a wireless advertisement frame having a source address field that indicates a reachable node being advertised, a destination address field that indicates a destination to which the reachable node is to be advertised, a transmitter address field that indicates a transmitting node from which the wireless advertisement frame is received, and a receiver address field that indicates the access point. The wireless access point then transmits a reflected wireless advertisement frame having a source address field that indicates the reachable node, a destination address field that indicates the destination, a transmitter address field that indicates the wireless access point, and a receiver address field that indicates both a plurality of receivers the reflected wireless advertisement frame is to be accepted by, and a node that is to be excluded from accepting the reflected wireless advertisement frame.
