  • Patent number: 8787190
    Abstract: A system, a network node, a router, a method and a program used to determine a bottleneck bandwidth on a multi-hop path between a source and destination node is presented. The method comprises receiving probe packets by a first hop node in the multi-hop path, measuring a bandwidth on a link between the first hop node and a next hop node in the multi-hop path, generating a bandwidth discovery packet including the measured bandwidth, transmitting the BDP to the next hop node, relaying the probe packets to the next hop node, and determining if the next hop node is a last-hop node on the multi-hop path. A last hop node records the measured bandwidth from the BDP, adjusts the delay between the probe packets based upon the bandwidth and relaying the probe packets to the destination node. The destination node determines the bottleneck bandwidth based on the delay between the probe packets.
