Patent number: 9992133Abstract: 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.Type: GrantFiled: October 21, 2016Date of Patent: June 5, 2018Assignee: Juniper Networks, Inc.Inventors: Pradeep S. Sindhu, Philippe Lacroute, Matthew A. Tucker, John D. Weisbloom, David B. Winters

Patent number: 5422880Abstract: A method and apparatus for exchanging communication cells in a communication controller, wherein an arbiter determines transmission requests for each of a plurality of communication modules in the communication controller. Each communication module has a transmit signal line and a receive signal line coupled to a switching circuit in the communication controller. The arbiter selectively couples the transmit signal lines to the receive signal lines according to the transmission requests. The communication modules transmit communication cells through the switching circuit, while the arbiter determines new transmission requests from each communication module.Type: GrantFiled: April 5, 1993Date of Patent: June 6, 1995Assignee: Stratacom, Inc.Inventors: Ross S. Heitkamp, Charles M. Corbalis, William N. Bedell, Frederick R. Enns, Amar S. Gupta, John D. Weisbloom
