ABSTRACT:
An embodiment of the invention provides a flexible bandwidth advertisement method that can reduce the number of routing updates that are sent in a network. In an embodiment of the invention, a method of reducing available bandwidth updates in a link in a communication system is provided. The method includes setting a range of threshold values. An actual available bandwidth in the link is then changed. If the actual available bandwidth changes from a first value within the range of threshold values to a second value within the range of threshold values, then a transmission of an available bandwidth update on the link is then prevented.
