%X At the 14th WoTUG Technical Meeting at Loughborough
   University in September 1991, Graeme Tozer from INMOS
   described the architecture of the IMS B300 Ethernet
   Interface. This product supports four external transputer
   networks, providing each with an Iserver interface to
   Ethernet and connectivity to a host Iserver running on a
   processor elsewhere on the Ethernet. Performance claims in
   the range 200\-300 kbytes per second were made for raw TCP
   transfers between a typical Unix workstation and transputers
   networked to it using the B300. This paper outlines the
   techniques which the author has used recently to enhance the
   performance of his own pipelined TCP/IP implementation for
   Ethernet to achieve throughputs of up to 925 kbytes per
   second on substantially similar hardware. Many of these
   techniques are equally appropriate to any large
   communicating process application.
