Internet-Router Buffered Crossbars Based on Networks on Chip

Executive Summary

The scalability and performance of the Internet depends critically on the performance of its packet switches. Current packet switches are based on single-hop crossbar fabrics, with line cards that use virtual output-queueing to reduce head-of-line blocking. In this paper, the authors propose to use a multi-hop Network On a Chip (NOC) as the crossbar fabric, with FIFO-queued line cards. Current high-performance Internet packet switches are based on crossbar fabrics and come in two flavours: unbuffered and internally buffered.
