IBperf: A Testing and Evaluation Model of IB Datacenter Transmission Control
Datacenter is the important infrastructure to provide resource and service in Internet. Due to the widely observed congestion, all kinds of transmission control mechanisms have been proposed to satisfy diverse network performance demands. Based on InfiniBand (IB) which is widely applied for datacenter construction, this paper proposed a generic testing and evaluation platform IBperf to verify transmission control protocols. We designed a central controller to instruct distributed clients to generate different communication patterns and execute commands of the protocol. The transmission performance can be derived based on the captured packets and digest. In the experiment, IB congestion control (CC) was evaluated through IBperf on our real IB platform. IBperf showed the improvement of fairness and throughput with low overhead based on CC mechanism. It proved IBperf to be an effective tool for the evaluation of IB datacenter.
