Abstract
A space switch includes a buffer having a plurality of serial inputs, a plurality of de-serializers, each coupled to a respective input, a plurality n of buffers and a media access controller having inputs coupled to the plurality of de-serializers, data outputs coupled to the buffers, and two control outputs coupled to respective buffers for buffering input data at a clock rate one-nth that of the input data and a switch fabric connected to the buffers for matching buffer data throughput with switch data throughput. Preferably the buffer is a bifurcate buffer. This space switch described ensures matching of buffer and switch fabric throughput.
Claims14
A space switch comprising:
- a plurality of serial inputs;
- a first media access controller having inputs coupled to each of the plurality of serial inputs;
- a second media access controller having inputs coupled to a subset of the plurality of serial inputs;
- a first buffer coupled to receive a first set of parallel data and a first control output from the first media access controller;
- a second buffer coupled to receive a second set of parallel data and a second control output from the first media access controller in a first configuration, and coupled to receive a third set of parallel data and a third control output from the second media access controller in a second configuration;
- and
- a switch fabric coupled to receive the first and second sets of parallel data from the first and second buffers in the first configuration, and coupled to receive the first and third sets of parallel data from the first and second buffers in the second configuration.
