First Claim
Patent Images
1. A method of evaluating routing performance within a switching network, comprising the steps of:
- transmitting a set of media packets via the switching network with each of the media packets comprising information for defining a level of routing service selected from one or both of a routing priority or a drop precedence;
receiving the set of media packets;
determining received packets with communication problems;
statically accumulating received packets with communication problems by level of routing service; and
indicating routing problems upon higher level of routing service media packets with communication problems having a greater statistic occurrence than lower level of routing service media packets with communication problems.
