Abstract
In one aspect, the disclosure includes an apparatus comprising a processor configured to receive node protection backup route data at an upstream node and determine at least one backup route to at least one merge point node of a protected link or node according to the node protection data. In another aspect, the disclosure includes an apparatus comprising a processor configured to: receive at an upstream component information from a downstream component, wherein the received information comprises one or more of the following data elements related to one or more merge point nodes of a protected node: a number of leaf nodes, a plurality of merge point node addresses, a plurality of merge point node label reserve times and a plurality of merge point node forwarding labels, and establish a backup tunnel at the upstream component using at least one of the data elements received from the downstream component.
