摘要： A method is provided in one example embodiment and includes receiving a plurality of packets and generating a data record that is based on information associated with the packets. The data record includes a synchronized time window field that defines a time boundary at which data aggregation associated with the data record is stopped, where the synchronized time window field remains constant as the data aggregation associated with the data record occurs. In other embodiments, the method includes creating a new cache entry for new packets arriving at a network element, where the new cache entry is created in response to a value of the synchronized time window field changing. The synchronized time window field can include a window size attribute that defines how long the synchronized time window remains unchanged.

摘要： 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.
