Field programmable port extender (FPX) for distributed routing and queuing

  title={Field programmable port extender (FPX) for distributed routing and queuing},
  author={John W. Lockwood and Jonathan S. Turner and David E. Taylor},
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. FPX modules reside at the edge of the WUGS switching fabric. Physically, the module is inserted between an optical line card and the WUGS gigabit switch back-plane… CONTINUE READING
