Modular router architecture for high-performance interconnection networks

Abstract

Usmjerivači (ruteri) velikog kapaciteta su temeljni moduli mreža za široku međupovezanost sustava u računalnim sustavima velikog kapaciteta. Kolektivnom interakcijom oni osiguravaju pouzdanu komunikaciju između računalnih čvorova i upravljaju komunikacijskim protokom podataka. Postupak razvoja specijalizirane arhitekture usmjerivača vrlo je složen i zahtijeva razmatranje mnogih čimbenika. Arhitektura usmjerivača velikog kapaciteta uvelike ovisi o mehanizmu za reguliranje protoka budući da on upravlja načinom na koji se paketi prenose kroz mrežu. U radu se predlaže nova visoko učinkovita arhitektura usmjerivača "Step-Back-On-Blocking".High performance routers are fundamental building blocks of the system wide interconnection networks for high performance computing systems. Through collective interaction they provide reliable communication between the computing nodes and manage the communicational dataflow. The development process of specialized router architecture has high complexity and it requires many factors to be considered. The architecture of the high-performance routers is highly dependent on the flow control mechanism, as it dictates the way in which the packets are transferred through the network. In this paper novel high-performance "Step-Back-On-Blocking" router architecture has been proposed
