Title:
METHOD FOR DYNAMICALLY ALLOCATING BANDWIDTH TO TRAFFIC HAVING VARIABLE DATA RATE IN NETWORK
Document Type and Number:
Japanese Patent JP3953875
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide an improved and comprehensive method and a system for dynamically allocating a network resource to applied traffic, by taking the feature of a signal in different frequency subbands into account, in a re-negotiation time which is calculated asynchronously.
SOLUTION: The method dynamically allocates bandwidth for traffic, having a variable data rate in a network. A data rate of the traffic, received from the network, is measured during fixed length time intervals. A predetermined number of consecutive data rates are grouped into overlapping vectors. A discrete wavelet transform is applied to each overlapping vector, to determine the frequency bands for each vector, and the frequency bands of each vector are analyzed to determine an associated energy of the data rate. Then, the bandwidth is allocated to the traffic according to the associated energy, when the traffic is transmitted.
