摘要： Described are methods and communications network for carrying pseudowires over packet-switched network. A communication network includes a packet-switched network (PSN), a first provider edge (PE) device in communication with a second PE device through the PSN, and a pseudowire (PW) established between the PE devices for emulating a service across the PSN. The PW has a Virtual Circuit Connection Verification (VCCV) control channel that carries an Ethernet Operations, Administration, and Maintenance (OAM) message. In some embodiments, various data plane encapsulation formats enable a PW to emulate an Ethernet or a non-Ethernet service over an Ethernet PSN. Each encapsulation format includes an Ethernet tunnel header and a PW header that encapsulates an Ethernet or non-Ethernet payload.

摘要： A technique for operating a network involves controlling the black-holing of traffic by forcing customer source MAC address (CMAC)-to-backbone source MAC address (BMAC) associations at provider backbone bridge (PBB) provider edge (PE) devices to be flushed from their corresponding forwarding information bases (FIBs) in response to a service failure so that new CMAC-to-BMAC associations, which are reflective of a secondary traffic path, are learned faster than they would otherwise be learned if the network had relied on native functionality to learn new CMAC-to-BMAC associations that are reflective of the secondary traffic path.

摘要： A technique for operating a network involves controlling the black-holing of traffic by selectively redirecting unicast traffic destined for a dual-homed customer equipment (CE) device from a first provider backbone bridge (PBB) provider edge (PE) device to a second PBB PE device in response to a service failure. Unicast traffic is selectively redirected from the first PBB PE device to the second PBB PE device for a time interval that is long enough to enable the customer source MAC address (CMAC)-to-backbone MAC address (BMAC) association of the second PBB PE device to be learned by other PBB PE devices.
摘要翻译：用于操作网络的技术涉及通过选择性地将发往双归属客户设备（CE）设备的单播流量从第一提供商骨干网桥（PBB）提供商边缘（PE）设备重定向到第二PBB来控制流量的黑洞 PE设备响应服务故障。单播流量被选择性地从第一PBB PE设备重定向到第二PBB PE设备，时间间隔足以使得客户源MAC地址（CMAC）到第二PBB PE的骨干MAC地址（BMAC）关联设备由其他PBB PE设备学习。
