The OpenSM/OFED stack has only recently (March 2008) gained support for QoS, but without any support for bandwidth limiting/admission control. Previous research has shown that admission control is necessary in order to ensure low latency operation when network load is high. Therefore it is demand for a admission control scheme to supplement the existing OpenSM/OFED/InfiniBand QoS features.

The purpose of this thesis is to suggest and evaluate admission control schemes for OpenSM/OFED/InfiniBand.

What you will do:

• you will suggest, analyse, and evaluate admission control schemes for InfiniBand
• you will make performance measurements on real hardware
• you will implement the suggested admission control schemes in the C language as part of the OpenSM/OFED software stack

What you will learn:

• you will get to know the InfiniBand architecture, a state of the art high performance networking technology
• you will obtain a thorough understanding of the OpenSM software and  the OFED stack
• you will participate in a large open source development project
• you will learn to analyse network performance
