ABSTRACT:
This invention relates to an apparatus and method for reducing the transmission of data on a data communications network by obtaining data from a cache rather than by transmitting the data. This method maintains an indexed cache of data from previous transmissions. Then, when duplicate information is to be transmitted, it can be replaced by a flag and an index to the cached data. This reduces the amount of data to be transmitted and increases the apparent rate of transfer.
