Abstract
An approach is disclosed for steering network traffic away from congestion hot-spots to achieve better throughput and latency. In one embodiment, multiple Foo-over-UDP (FOU) tunnels, each having a distinct source port, are created between two endpoints. As a result of the distinct source ports, routers that compute hashes of packet fields in order to distribute traffic flows across network paths will compute distinct hash values for the FOU tunnels that may be associated with different paths. Probes are scheduled to measure network metrics, such as latency and liveliness, of each of the FOU tunnels. In turn, the network metrics are used to select particular FOU tunnel(s) to send traffic over so as to avoid congestion and high-latency hotspots in the network.
