摘要： The protection of multi-segment pseudowires by utilizing backup paths is disclosed herein. Disclosed embodiments include methods that establish at least one backup path for multi-segment pseudowires, the establishing being performed prior to detection of failure in the primary path. Upon detecting a path failure, the detected failure is signaled to the head-end, a backup path is chosen, and reachability information associated with the chosen backup path is signaled across the backup path before reverse traffic is switched to the backup path. In other disclosed embodiments, apparatus are configured to establish, prior to detection of failure in the primary path, at least one backup path for the multi-segment pseudowire.

摘要： Techniques for distributing digital content include receiving provider content over a network connection at a customer premises node located on premises of a first customer. The provider content is offered by a network service provider different from the first customer. Provider data based on the provider content is stored in non-volatile storage on the customer premises node of the first customer. It is determined whether conditions are satisfied for sending the provider content to a second customer different from the first customer. If it is determined that such conditions are satisfied, then the provider data is retrieved from the non-volatile storage, and data based on the provider data is sent over the network connection for receipt by the second customer. Thereby a customer premises node serves as a cache of provider content for other customer premises nodes on the same last mile segment or access network.

摘要： A method and apparatus for network monitoring using a proxy are disclosed. In one embodiment, a method generally comprises receiving at a proxy, path information for a label switched path (LSP) from a forwarding device located in the LSP, generating a connectivity verification message based on the path information, adding a proxy label to the connectivity verification message, and transmitting the connectivity verification message to the forwarding device. The proxy label is configured to inject the connectivity verification message into a forwarding plane at the forwarding device and the connectivity verification message is configured for transmittal from the forwarding device over the LSP to a destination node to verify a forwarding path associated with the path information received from the forwarding device.

摘要： A network element and method for marking traffic in a packet-switched data network which comprises a distributed hierarchical naming system and the network element. The network element comprises a marking rule store for storing marking rules, in which each marking rule is indicative of a quality of service level allocated to traffic on a connection impinging on the network element. The network element derives from the distributed hierarchical naming system quality of service level data for a connection, stores in the marking rule store a marking rule for the connection based on the retrieved quality of service level data and marks traffic on the connection in accordance with the marking rule.
