<p>A computer readable storage medium containing a program element for execution by a computing device in a network having a plurality of linked nodes, wherein paths for conveying data traffic are defined in the network, each path traversing an ordered set of nodes from among the plurality of nodes. The program element includes a first program component adapted to assign, for a particular node that is intermediate at least one particular path, a particular tunnel route to the protection of a particular subset of the at least one particular path against failures occurring downstream from the particular node along the particular subset of the at least one particular path. By providing protection for portions of a path without requiring that such protection be established on an end-to-end basis, the time, bandwidth and memory required to protect data traffic is reduced.</p> |
