US Patent:

6347334, Feb 12, 2002

Filed:

Jan 6, 1999

Appl. No.:

09/225949

Inventors:

Kenneth J. Fredericks - Boulder CO
Michael E. ODonnell - Westminster CO
Joseph C. Elliott - Hopewell Junction NY

Assignee:

McData Corporation - Broomfield CO

International Classification:

H04L 1224

US Classification:

709220, 709223, 709230, 370244, 370248, 370250

Abstract:

A method for implementing a link level service in a computer network having a first port device and a second port device. Node identification data is stored in the second port device. A physical-layer communications coupling is provided between the first port device and the second port device which may be a point-to-point, loop, or switched circuit connection. The first port device sends a request node identification (RNID) message addressed to the second port device. The second port device creates an accept message and copies stored node identification data into the accept message. The second port device sends the accept message to the first port device.

International Classification:

G06F 506

US Classification:

710 60, 710 36, 370398, 370466

Abstract:

A data communication architecture including a plurality of devices having input/output (I/O) ports supporting communication at a first rate and a data processor having a number of I/O ports where each I/O port supports data communication at a second data rate. The second data rate is at least double the first data rate. A communication link coupled to one of the data processor I/O ports supports the second data rate. A bridge device is coupled to the communication link and to the I/O ports of the plurality of devices. The bridge device translates the communication link at the second data rate to a plurality of communication links at the first data rate, where the plurality of communication links at the first data rate are substantially independent of each other.
