Queuing Structure And Method For Prioritization Of Frames In A Network Switch

View page
US Patent:
6487212, Nov 26, 2002
Filed:
Dec 18, 1997
Appl. No.:
08/993147
Inventors:
Bahadir Erimli - Mountain View CA
Ian Crayford - San Jose CA
Chandan Egbert - San Jose CA
Assignee:
Advanced Micro Devices, Inc. - Sunnyvale CA
International Classification:
H04L 1228
US Classification:
370413, 370230, 370429
Abstract:
A method and arrangement for queuing data in a prioritized manner has a queue with a single queue write side in which data entries are input to the queue. The queue also has a plurality of queue read sides, with each read side having a different priority level. An entry exiting from the queue write side is examined to determine the priority level of the entry, and then placed into the queue read side with the matching priority level as the entry. The queue read sides form the output of the queue, and are polled and emptied so that the higher priority queues are emptied completely before emptying lower priority queues.

Network Transceiver For Steering Network Data To Selected Paths Based On Determined Link Speeds

US Patent:
6556589, Apr 29, 2003
Filed:
Jan 4, 1999
Appl. No.:
09/225219
Inventors:
Stephen McRobert - Sunnyvale CA
Ian S. Crayford - San Jose CA
Assignee:
Advanced Micro Devices, Inc. - Sunnyvale CA
International Classification:
H04J 316
US Classification:
370501, 370465
Abstract:
A novel method of operating repeaters or other hub devices in a local area network, such as one conforming to Ethernet protocol, in which there are a plurality of repeater interfaces of respectively different data rates for communicating with a link partner on a network medium. The methodology comprises determining the data rate of operation of the link partner, and based on that data rate, automatically steering data between the network medium and a selected one of the repeaters. In a preferred embodiment, a network transceiver comprises one or more physical layer devices (PHY), and a plurality of shared data busses corresponding, respectively, to the speeds of operation of the repeaters, for interconnecting the repeaters and one or more of the physical layer devices. A multiplexer interconnects each of the one or more physical layer devices to a selected one of the plurality of busses, and an auto-negotiation unit controls the multiplexer to interconnect the physical layer devices to corresponding busses selected depending on the operating speed of the link partner.

Optimized Mii For 802.3U (100 Base-T) Fast Ethernet Phys

View page
US Patent:
6704296, Mar 9, 2004
Filed:
Sep 16, 1996
Appl. No.:
08/743049
Inventors:
Ian Crayford - San Jose CA
Ramesh Sivakolundu - Fremont CA
Bing Cheng - Mountain View CA
Assignee:
Advanced Micro Devices, Inc. - Austin TX
International Classification:
H04L 1256
US Classification:
370279, 370492, 370501
Abstract:
A media independent interface for interconnecting an integrated repeater front-end with one or more integrated interface devices, each having several physical layer devices for operation in conformance with IEEE 802. 3u. The media independent interface, in a repeater implementation, shares transmit and receive data channels, and provides for dedicated control signals, thereby multiplexing shared channels across all of the physical layer devices in the integrated interface device.

US Patent:
6885657, Apr 26, 2005
Filed:
Nov 30, 1999
Appl. No.:
09/452043
Inventors:
Ted F. Rabenko - Duluth GA, US
Ian Crayford - San Jose CA, US
Assignee:
Broadcom Corporation - Irvine CA
International Classification:
H04L012/66
US Classification:
370352, 37039542, 370429, 370463
Abstract:
The present invention includes a network telephone having a microphone coupled to provide voice data to a network, a speaker coupled to facilitate listening to voice data from the network, a dialing device coupled to facilitate routing of voice data upon the network, a first port configured to facilitate communication with a first network device, a second port configured to facilitate communication with a second network device and a prioritization circuit coupled to apply prioritization to voice data provided by the microphone.

US Patent:
6970419, Nov 29, 2005
Filed:
Aug 7, 1998
Appl. No.:
09/131141
Inventors:
Mohan V. Kalkunte - Sunnyvale CA, US
James L. Mangin - San Ramon CA, US
Ian Crayford - San Jose CA, US
Assignee:
Nortel Networks Limited - St. Laurent
International Classification:
H04J001/16
US Classification:
370230, 370235, 370412
Abstract:
A method for preserving frame order of a plurality of frames transmitted over a plurality of communication links is presented. In accordance with the teachings of the present invention, the method includes receiving up to a plurality of indications denoting commencement of frame transmission on a corresponding plurality of communication links, and assigning a pointer value to a record in a buffer for each of said frames based, at least in part, on a relative order in which the indications are received.
