QoS in InfiniBand Subnetworks
September 2004 (vol. 15 no. 9)
pp. 810-823

Abstract—The InfiniBand Architecture (IBA) has been proposed as an industry standard both for communication between processing nodes and I/O devices and for interprocessor communication. It replaces the traditional bus-based interconnect with a switch-based network for connecting processing nodes and I/O devices. It is being developed by the {\rm{InfiniBand^{SM}}} Trade Association (IBTA) in the aim to provide the levels of reliability, availability, performance, scalability, and quality of service (QoS) required by present and future server systems. For this purpose, IBA provides a series of mechanisms that are able to guarantee QoS to the applications. In previous papers, we have proposed a strategy to compute the InfiniBand arbitration tables. In one of these, we presented and evaluated our proposal to treat traffic with bandwidth requirements. In another, we evaluated our strategy to compute the InfiniBand arbitration tables for traffic with delay requirements, which is a more complex task. In this paper, we will evaluate both these proposals together. Furthermore, we will also adapt these proposals in order to treat VBR traffic without QoS guarantees, but achieving very good results. Performance results show that, with a correct treatment of each traffic class in the arbitration of the output port, all traffic classes reach their QoS requirements.
