    Abstract: Techniques for reducing the latency in performing a failover from a protected connection to its backup connection when a network event is detected affecting the protected connection. In an MPLS network, techniques are provided for failing a protected LSP to a backup LSP in a fast and efficient manner. In one embodiment, the faster failover is facilitated by storing protected LSPs and their backup LSPs information in the data plane, such as locally on a linecard.

    Abstract: Techniques for dynamically establishing and configuring a liveliness detection session for a local repair connection of a connection. In one set of embodiments, a signaling message is received at a node configured to maintain a local repair connection for a connection. A configuration parameter is identified in the signaling message, where the configuration parameter pertains to a liveliness detection mechanism or protocol. A liveliness detection session is then established for the local repair connection based on the configuration parameter.

    Abstract: Techniques for configuring a local repair connection for a protected connection including determining a path for the local repair connection. The path traversed by a local repair connection starts at a node in the path associated with the protected connection and ends at a merge point node in the path associated with the protected connection that is downstream from the start node. In one embodiment, the merge point node may even be more than two hops downstream from the start node in the path associated with the protected connection. The local repair path may include zero or more nodes that are not included in the path associated with the protected connection. Techniques are also described for optimizing the path associated with a local repair connection.
