Abstract
The method is for adjusting a bandwidth capacity of a dynamic channel in a network topology by allocating a bandwith value (b1) to the dynamic channel wherein the channel extends from a first node to a second node in a network topology. The traffic flow in the channel is measured to calculate a measured bandwidth value (B1). The allocated bandwidth value (b1) is dynamically adjusted to the measured bandwidth value (B1) so adjust the bandwidth (b1) to the actual bandwidth used.
Claims7
A method of adjusting a bandwidth capacity of a dynamic channel in a network topology, comprising:
- (a) allocating a bandwith value (b1) to the dynamic channel, the channel extending from a first node to a second node in the network topology;
- (b) measuring a traffic flow in the channel to calculate a measured bandwidth value (B1);
- (c) in a first comparison unit, determining if the measured bandwidth value (B1) is greater than the allocated bandwidth value (b1) minus an offset value (Of);
- (d) when the bandwidth value (B1) is greater than the bandwidth value (b1) minus the offset value (Of), determining if the bandwidth value (B1) plus the offset value (Of) plus a delta parameter value (De) are greater than a peak bandwidth parameter value (p), the parameter value (p) being a maximum allowable bandwidth value;
- (e) when the bandwidth value (B1) plus the offset value (Of) plus the delta parameter value (De) are greater than the peak bandwidth parameter value (p), increasing the bandwidth value (b1) to the peak bandwidth parameter value (p);
- and
- (f) when the bandwidth value (B1) plus the offset value (Of) plus the delta parameter value (De) are not greater than the peak bandwidth parameter value (p), increasing the bandwidth value (b1) to a bandwidth value (b2), the bandwidth value (b2) being greater than the bandwidth value (b1).
