In general, techniques are described that may allow a network element to analyze the performance of a network without using external equipment external to the network. In one example, a method includes injecting a plurality of data units onto the network, forwarding the plurality of data units around the network loop, injecting at least one timing data unit on to the network, forwarding the at least one timing data unit around the network loop, and determining at least one latency statistic correlated to the at least one characteristic of the forwarded plurality of data units.

Network latency testing

Techniques for network packet flow management are described herein. For example, example methods may include receiving, at a first network device, a first flow identifier that identifies a first content of a first packet flow and a second flow identifier that identifies a second content of a second packet flow, wherein the first flow identifier and the second flow identifier are generated by a second network device. Such methods may also include receiving priority information indicating that the first content has a first priority and that the second content has a second priority that is lower than the first priority. Moreover, example methods may include transmitting the first packet flow and a modified second packet flow that includes the priority information to one or more other network devices.
