ABSTRACT:
Data are rerouted over a network having a uniform-capacity Tandem Connection by detecting a failure in a link in a path, maintaining the path through a Tandem Connection that does not include the failed link, and rerouting the data through the Tandem Connection based on information embedded in a tandem layer in the data, and independent of the constituent payload capacities within the tandem connection.
