Modern mobile communication networks handle
user traffic in terms of data streams rather than single packets.
Resources are allocated per stream as a reaction on its history.
In particular, the network´s delay figure depends on the entire
traffic pattern injected by the user. This work aims to find
a comprehensive measure for the delay behavior of reactive
networks. A novel measurement methodology is introduced which
enables the fast assessment of the delay performance for a
multitude of traffic patterns. The results are condensed to a
handful of typical classes by simultaneously minimizing the loss
of information. Those classes enable an intuitive representation
of the network´s latency behavior. Further, they indicate which
patterns are preferable for fair benchmarking. We demonstrate
the practicability of the approach by benchmarking operational
networks, namely, LTE (non-reactive) and HSPA (reactive). The
analysis shows that the proposed method works well for both
technologies, outperforming standard methods which a priori
assume non-reactiveness of the network under test.
