Lightweight Determinism in Large-Scale Networks

The dataset was used to produce two figures (Fig. 4 and Fig. 5) in the experimental section of a manuscript submitted for review to the IEEE Communications Magazine. The title of the submission is Lightweight Determinism in Large-Scale Networks. The submission describes a novel approach to the realization of network determinism in packet-switched nbetworks of generic size and topology. The approach builds on a novel per-flow traffic shaper that controls the ingress links of the deterministic network domain, where transmission opportunities are distributed to packet queues based not only on their guaranteed service rates, but also on awareness of the network paths over which the respective flows are routed. The fiirst ffigure shows the distribution of maximum-latency samples collected in a proof-of-concept system that reproduces a small data-center fabric with Clos topology. The second figure compares the distributions of service oppoirtunities to the queues of configured flows that are obtained with a conventional per-flow shaper (called FLAT) and with the new per-flow shaper described in the submission (called LD).
