Abstract:
A data communications hub comprising:a concentrator, the concentrator having a first number of inputs carrying data at a first data rate and a second number of outputs carrying data at the first data rate, at least the second number of outputs being selected by sampling the first number of inputs to determine an average number of inputs carrying live data packets at any given time, wherein the first number is larger than the second number; and a multiplexer, the multiplexer having an output and having inputs coupled to the second number of outputs of the concentrator, wherein the output carries data at a second data rate which is greater than the first data rate, wherein the concentrator determines which of the first number of inputs have the live data packets and provides the live data packets to one or more of the second number of outputs, and wherein the multiplexer receives the live data packets from the concentrator and interleaves the live data packets onto the output of the multiplexer.
