A1
Abstract:
A method, apparatus and system for measuring a network path, capable of improving the efficiency for measuring the network path. The method comprises: a first exchange node in a CLOS exchange network obtains a first aggregate available bandwidth of a path from the first exchange node to a second exchange node; the first exchange node obtains a first available bandwidth of a path from a first destination port of a third exchange node to the first exchange node, the third exchange node being a lower exchange node connected by the first exchange node; the first exchange node obtains a second available bandwidth of a path from the second exchange node to a forth exchange node, the fourth exchange node being a lower exchange node connected by the second exchange node; and the first exchange node obtains a second aggregate available bandwidth of a path from a first destination port of the third exchange node to the fourth exchange node, the second aggregate available bandwidth being a minimum available bandwidth among the first aggregate available bandwidth, the first available bandwidth and the second available bandwidth.
