Title: APPARATUS AND METHOD FOR PROVIDING A ROBUST ROUTING CONFIGURATION
Abstract:
A system and method for providing a routing configuration is disclosed. The routing configurations are built according to monitored traffic matrices and predicted traffic matrices. The build set of routing configurations are a set of overlapping robust routing configurations. The building provides one or more routing configurations that perform better with upcoming traffic matrices. The routing configurations are computed in advance so that they can be pre-fetched before the real need for the new routing configuration commences. The pre-fetched routing configurations are easy to activate as they have been computed and fetched in advance. Because of overlapping the activating can be executed fluently.
