Abstract
A high capacity distributed switching system comprises electronic edge nodes connected to a balanced bufferless switch which may be electronic or optical. The balanced bufferless switch comprises a balanced connector and a switch fabric. The balanced connector comprises an array of temporally cyclic rotator units having graduated rotation shifts and each having a prime number of output ports. The switch fabric may be a mesh interconnection of switch modules. Due to the use of the balanced connector, establishing a path through the switch fabric requires at most a second-order time-slot matching process for a high proportion of connection requests with a much reduced need for a third-order time-slot matching process required in a conventional mesh structure.
Claims1
A balanced connector comprising:
- a plurality of input ports;
- and
- a plurality of output ports, said output ports divided into a number of output groups each output group including at least two output ports;
- said balanced connector operable to change the connectivity of said input ports to said output ports during successive time intervals in a time frame having a predefined number of time intervals so that:
- during any two successive time intervals, each input port connects to output ports in different output groups;
- during said time frame each input port connects to an output port in each output group;
- and
- during said time frame, any combination of two input ports connects only once to output ports of the same output group.
