Realisation and performance of IEEE 1355 DS and HS link based, high speed, low latency packet switching networks

摘要

We report on the construction of a 1024 node switching network using IEEE 1355 DS link technology. The nodes are interconnected by a switching fabric based on the STC104 packet switch. The system has been designed and constructed in a modular way in order to allow a variety of different network topologies to be investigated. Network throughput and latency have been studied for different topologies under various traffic conditions including those expected within the second level trigger of the ATLAS experiment. Initial experience using 1 Gbaud IEEE 1355 HS links and switches is also presented.
