Abstract
A method for minimizing bandwidth allocation for alternative routes within a network provides a management system for managing routes of services, provides a plurality of guaranteed bandwidth (GWB) services, assigns to each GBW-service a traffic class (TC), and calculates for each GBW-service of a protected TC an active route and an alternative route. The active route is a planned route in case of absence of a respective network failure and the alternative route is the route which guarantees that, in case of a network failure with respect to the active route, the GBW-service is protected. Further, a first optimized protection mode is provided to be assigned to all the GBW-services belonging to a given protected TC. The first optimized protection mode has a first optimization step including reserving bandwidth for each GBW-service only once for each network resource employed by the active and/or the alternative route of each GBW-service.
