Fast Higher Bandwidth X.
John M. Danskin, Qin Zhang, D. M. Abrahams-Gessel · 1995
This paper proposes an X Window System protocol compression scheme called Fast Higher Bandwidth X (FHBX). Previous X protocol compression schemes were either much slower (Higher Bandwidth X) or much less effective (Xremote). By using an application specific predictive hashing technique, FHBX is able to deliver three times the compression performance of Xremote, while running ten times as fast as HBX. The family of structured compression techniques illustrated by FHBX is applicable to other structured protocols, and should enable a host of interactive applications on low bandwidth wireless devices and telephone links. 1 Introduction This research is targeted at the vast numbers of networks which are, and which will continue to be, too slow. These networks include normal telephone connections, wireless connections, internet connections, and ISDN connections. If the current rate of increase in CPU performance holds, unloaded 10Mbit/sec Ethernet connections will be candidates for softwar...
