Abstract:
A method for controlling a Multiprotocol Label Switching (MPLS) traffic engineering (TE) system by dynamically adjusting a current set bandwidth of a TE tunnel, the method comprising the repetitive steps of:setting an event in which a byte counter is to be read, the byte counter keeping track of an average traffic flow through the TE tunnel; wherein at the occurrence of the event, a processing unit performs the steps of: reading the byte counter to determine the average traffic flow of the TE tunnel; comparing the average traffic flow with the current set bandwidth of the TE tunnel; determining whether the current set bandwidth needs to be adjusted and if so, calculating an adjusted bandwidth and causing a TE module to perform the steps of, calculating a path that meets a requirement of the adjusted bandwidth; and setting the TE tunnel according to the calculated path.
