Field programmable port extender (FPX) for distributed routing and queuing
John W. Lockwood, Jon S. Turner, David E. Taylor · 2000
Field Programmable Gate Arrays (FPGAs) are being used to provide fast Internet Protocol (IP) packet routing and advanced queuing in a highly scalable network switch. A new module, called the Field-programmable Port Extender (FPX), is being built to augment the Washington University Gigabit Switch (WUGS) with reprogrammable logic.
