vncs Vp Maximum Acceptable Delay

1.3.6.1.4.1.562.2.4.1.44.3.2.1.12

This attribute specifies an upper bound on the delay of a route, which is the sum of the delays of all trunks on the route. It should be provisioned with a reasonable maximum acceptable delay for the end to end one way delay of a 512-byte packet. Remember, that the trunk during its staging measures a measuredRoundTripDelay. This delay is divided by two and truncated to an integer number of milliseconds to provide a one way delay which is used to populate the delay in this trunk object in the topological database. The value includes emission, propagation, and queuing delays. A 512-byte packet is used to perform the measurement. If for any trunk the half of the trunk's measuredRoundTripDelay is larger than the maximumAcceptableDelay, then that trunk is not considered during the route selection. While a shortest route is being selected, the route delay is being compared with the maximumAcceptableDelay attribute, and this is done for any minimization criterion. No route is selected if the delay metric of the shortest route is larger than the maximumAcceptableDelay.
