<p>Independent heterogeneous computers are interconnected for oblivious, high speed, long distance communications. A printed circuit board with onboard RAM repeats all write commands through a data transmission media to a remote system. Each read and write cycle of the communicating computer is completed locally (using only local RAM). Apart from repeating write commands to a remote system, the invention is oblivious to the remote system. Data is transmitted from one machine to another without expensive communication protocols or transmission line latency induced wait states. A remote computer accesses network data only after it has been transmitted and stored in local memory. Multiple data transfers can be pipelined, that is, multiple datum may simultaneously reside in a high latency network/long transmission line. Although the time required to transmit any single datum remains proportional to the signal propagation delay, the time required to transmit multiple data is significantly reduced. Geographic separation, high speed transmission lines, low speed transmission lines, alternative means for data transmission, fault tolerance, one-way communications, multi-way communications, and high security can be supported by a single computer network of heterogeneous machines.</p> |
