Abstract

A switching device in a network system for transferring data includes one or more source line cards, one or more destination line cards and a switching fabric coupled to the source line cards and the destination line cards to enable data communication between any source line card and destination line card. Each source line card includes a request generator to generate a request signal to be transmitted in order to obtain an authorization to transmit data. Each destination line card includes a grant generator to generate and send back a grant signal to the source line card in response to the request signal received at the destination line card to authorize the source line card to transmit a data cell to the destination line card.
