ABSTRACT:
In a computer network including a plurality of processors coupled to a data bus, ones of the processors contending for the data bus to output data requests each output priority byes of their transmission header packets as a series of data bits. Every contending processor sequentially reads data present on the data bus. Each processor that reads a "one" on the bus corresponding to a "zero" output by that processor interprets this as a data collision yields the bus for data transmission purposes, but continues to read all data appearing on the data bus and compares it with corresponding bits of its own transmission header packet. Only the processor having highest priority detects no data collision, and continues to output its data request. If any other contending processor determines that the data request of the highest priority processor is identical or sufficiently similar to its own, it merges its request with that of the highest priority processor by reading the resulting data, thereby reducing waiting time especially in file-intensive operations.
