Document Type and Number:
Japanese Patent JP3309212
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide the network switch system by which a large scale network coping with increase in connected terminals is realized at a low cost in a form of a full cross point network and a transfer speed for transfer of small amount of data is enhanced.
SOLUTION: A mediation circuit 10 selects one request among request signals from transmitter sides 2-1-2-4 received via input ports 14-17 based on preset priority or the like and sends the result respectively to a request cross point 11, a data cross point 12 and a ready cross point 13, and the selected input ports 14-17 is given of an occupancy right of output ports 18-21. The request cross point 11, the data cross point 12 and the ready cross point 13 select each input signal from those of the input ports 14-17 and the output ports 18-21, based on an instruction from the mediation circuit 10.
