Abstract
A method to investigate congestion in a computer network may include network devices to route data packets throughout the network. The method includes, for example, sending a probe packet to network devices from a source node to gather information about the traffic queues at each network device that is examined by the probe packet. A routing table at each network device that receives the probe packet is based on the gathered information for respective each traffic queue.
