Abstract
Residence time is a variable part of the propagation delay of the packet. Information about the propagation delay for each transient node can be used as performance metric to calculate the Traffic Engineered route that can conform to delay and delay variation requirements. In an exemplary embodiment, a computing device uses special test packets to measure residence time. The computing device calculates routes to direct special test packets to one or more nodes. A node may calculate the residence time metric, such as a residence time variation (RTV), or residence time (RT) per ordered set of ingress and egress interfaces of the node. The computing device may also collect the residence time metric per test set from each node and may use this information to calculate the Test Engineered route.
