Resilient Routing Layers (RRL) and Multiple Routing Configurations (MRC) has been proposed as a new approach providing local and proactive recovery. RRL and MRC also provides a network manager with a simple set of sub-topologies as abstractions for the recovery routing. This paper will compare different methods for generating such layers and configurations along two para- meters, scalability and effects on routing of the recovered traffic.}, year = {2005}, number = {2005-15}, month = {September}, publisher = {Simula Research Laboratory}, }
