Dimensioning of switch fabric interfaces of high-throughput routers

Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review


High volume traffic presumes high-throughput routers that are connected together with high-speed links. Routers equipped with a number of high capacity links have to implement very powerful switch fabrics. Extending clock rates of a high performance switch fabric to line-cards leads to demanding electronics design and expensive line-card implementations even in cases when only moderate link-speeds are supported. Hence, innovations that allow switch fabric interfaces to operate at clock rates lower than those inside the switch core are welcome. This paper analyzes the interface between a line-card and a switch fabric to find dimensioning rules that enable lowered bit rates while maintaining loss-free operation of the switch fabric.
