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： A shared (proxy) OAM session is performed in a packet-based network on behalf of a plurality of connections. First and second connections are each routed between respective nodes of the network for carrying data traffic. The second connection shares a portion of the routing of the first connection. The shared OAM session is performed along a path which is co-routed with at least part of the shared portion of the routing of the first connection and the second connection. Failure notification signalling is propagated to an endpoint node of each of the first and second connections when the shared OAM session indicates a failure has occurred. The use of a shared OAM session reduces processing at nodes and reduces OAM traffic. Each connection can be a trunk, such as a PBT/PBB-TE trunk, or a service carried within a trunk.

摘要： Instead of alternatively utilizing only one fabric or the other fabric of a redundant pair, both fabrics simultaneously transmit duplicate information, such that each packet forwarding module (PFM) receives the output of both fabrics simultaneously. In real time, an internal optics module (IOM) analyzes each information chunk coming out of a working zero switch fabric; simultaneously examines a parallel output of a working one duplicate switch fabric; and compares on a chunk-by-chunk basis the validity of each and every chunk from both switch fabrics. The IOM does this by examining forward error correction (FEC) check symbols encapsulated into each chunk. FEC check symbols allow correcting a predetermined number of bit errors within a chunk. If the chunk cannot be corrected, then the IOM provides indication to all PFMs downstream that the chunk is defective. Under such conditions, the PFMs select a chunk from the non-defective switch fabric. Under error-free normal conditions, however, the PFMs select a chunk arbitrarily from a default switch fabric. In this way, each chunk in real time is selected from a non-defective source and is thus guaranteed to be error free. Accordingly, if a switch fabric fails, no information chunks are lost anywhere in the system.
摘要翻译：代替替代地仅使用冗余对的一个结构或另一个结构，两个结构同时发送重复信息，使得每个分组转发模块（PFM）同时接收两个结构的输出。实时地，内部光学模块（IOM）分析从工作的零交换结构出来的每个信息块; 同时检查工作的一个重复交换矩阵的并行输出; 并且以逐块为基础比较来自两个交换结构的每个块的有效性。 IOM通过检查封装到每个块中的前向纠错（FEC）校验符号来实现。 FEC检查符号允许校正块内的预定数量的位错误。如果块不能被纠正，则IOM向下游的所有PFM提供指示该块是有缺陷的。在这种情况下，PFM从无缺陷的交换结构中选择一个块。然而，在无错误的正常条件下，PFM从默认的交换结构中任意选择一个块。以这种方式，从无缺陷源选择实时的每个块，并且因此被保证是无错误的。因此，如果交换机结构发生故障，系统中的任何地方都不会丢失任何信息块。
