                                ABSTRACT

      At CITI, we run dataless AFS clients  over  dialup  IP  net-
      works.   Improving  Rx performance is critical to that task.
      In this paper, we report on our progress in adapting  Rx  to
      networks  characterized  by  low  bandwidth,  high delay, or
      variable round-trip time.  Our focus is on adding facilities
      for  congestion avoidance and control, and on compressing Rx
      headers.  Although our work is  ongoing,  we  have  overcome
      several   hurdles,  and  are  now  getting  impressive  data
      transfer rates over ordinary dialup lines.
