Abstract
In one embodiment, a method includes obtaining a first packet that has a first payload. The first payload identifies a first path between endpoints traversed by the first packet, and identifying information associated with a first node associated with the first path traversed by the first packet. The identifying information includes an arrival time that identifies approximately when the first packet arrived at the first node and a leaving time that identifies approximately when the first packet left the first node. A first service level agreement (SLA) parameter of the first path is determined by analyzing the arrival time and the leaving time, comparing the first SLA parameter with a second SLA parameter associated with a second path traversed by a second probe packet, and selecting the first path for sending packets if the first SLA parameter indicates a higher SLA level than indicated by the second SLA parameter.
