Abstract:
1. A method comprising: in response to traffic congestion along a primary downstream path to a second routing device, establishing an alternate path to the second routing device by way of a first routing device based on an available bandwidth of the first routing device and transmitting a portion of traffic bound for the second routing device along the alternate path, the second routing device being an immediate downstream neighbor; after establishing and transmitting the portion of the traffic along the alternate path, detecting a non-congestion condition along the primary downstream path to the second routing device; after detecting the non-congestion condition along the primary downstream path, delaying a determination of whether to remove the alternate path to the second routing device for a selected time period; detecting a continued non-congestion condition along the primary downstream path after the selected time period has elapsed; and in response to detecting the continued non-congestion condition along the primary downstream path, removing the alternate path and transmitting the traffic including the portion of the traffic along the primary downstream path to the second routing device.
