Non-Consecutive Data Readout Scheduler

View page
US Patent:
6343066, Jan 29, 2002
Filed:
Mar 9, 2001
Appl. No.:
09/802389
Inventors:
Robert Bradford Magill - Mishawaka IN
Kent Daniel Benson - Granger IN
Terry Jon Hrabik - South Bend IN
Assignee:
Tellabs Operations, Inc. - Naperville IL
International Classification:
G01R 3108
US Classification:
370230, 370412
Abstract:
Data switching systems for use in ATM and other packet and cell switching networks can more smoothly switch data if incoming data packets to be switched are re-ordered to avoid overwhelming an output port with too many consecutive packets to a particular destination. An apparatus and method for simply re-ordering data samples in a non-consecutive manner is computationally efficient and effective.

Methods And Apparatus For Managing Traffic Through A Buffered Crossbar Switch Fabric

US Patent:
6915372, Jul 5, 2005
Filed:
Jun 8, 2001
Appl. No.:
09/877502
Inventors:
Robert B. Magill - Mishawaka IN, US
Terry J. Hrabik - South Bend IN, US
Tara Javidi - Ann Arbor MI, US
Assignee:
Tellabs Operations, Inc. - Naperville IL
International Classification:
G06F013/00
US Classification:
710317, 710 56
Abstract:
A data routing mechanism is disclosed. The data routing mechanism includes virtual output queues (VOQs), corresponding to a first input port, that store data to be sent to one of a first and second output port. The data routing mechanism includes VOQs, corresponding to a second input port, that store data to be sent to one of the first and second output port. The data routing mechanism includes a switch fabric that includes a plurality of buffers at crosspoints between the first and second input ports and the first and second output ports. The data routing mechanism includes a first input scheduler that transmits a first data from the VOQs corresponding to the first input port to one of the plurality of buffers based on lengths of the VOQs corresponding to the first input port and a credit state of the plurality of buffers.

US Patent:
7061865, Jun 13, 2006
Filed:
Dec 12, 2001
Appl. No.:
10/021612
Inventors:
Robert Bradford Magill - Mishawaka IN, US
Kent Daniel Benson - Granger IN, US
Terry Jon Hrabik - South Bend IN, US
Assignee:
Tellabs Operations, Inc. - Lisle IL
International Classification:
H04L 12/56
US Classification:
370235, 3703954, 370412
Abstract:
Data switching systems for use in ATM and other packet and cell switching networks can more smoothly switch data if incoming data packets to be switched are re-ordered to avoid overwhelming an output port with too many consecutive packets to a particular destination.

Allocating Network Bandwidth

View page
US Patent:
7072295, Jul 4, 2006
Filed:
Sep 14, 2000
Appl. No.:
09/662194
Inventors:
Kent D. Benson - Granger IN, US
Robert B. Magill - Mishawaka IN, US
Terry J. Hrabik - South Bend IN, US
John B. Kenney - Granger IN, US
Assignee:
Tellabs Operations, Inc. - Naperville IL
International Classification:
H04J 1/16
US Classification:
370230, 370412
Abstract:
In allocating bandwidth to data for transfer through a network device, bandwidth is allocated to committed data traffic based on a guaranteed data transfer rate and a queue size of the network device, and bandwidth is allocated to uncommitted data traffic using a weighted maximum/minimum process. The weighted maximum/minimum process allocates bandwidth to the uncommitted data traffic in proportion to a weight associated with the uncommitted data traffic.

Method And Apparatus For Scheduling Packetized Data Flows In A Calendar-Based Arbitration Scheme

View page
US Patent:
7167485, Jan 23, 2007
Filed:
Dec 17, 2001
Appl. No.:
10/022628
Inventors:
Terry J. Hrabik - South Bend IN, US
Robert B. Magill - Mishawaka IN, US
Ravi Chandran - South Bend IN, US
Kent D. Benson - Granger IN, US
Assignee:
Tellabs Operations, Inc. - Naperville IL
International Classification:
H04L 12/43
H04L 12/56
H04L 12/26
US Classification:
370461, 3703954, 370235
Abstract:
An arbitration unit according to an embodiment of the present invention is disclosed. The arbitration unit includes an allocation unit that assigns a first number of slots in a frame to a first flow and a second number of slots in the frame to a second flow. The arbitration unit includes a scheduling unit that assigns first slot positions to the first number of slots in the frame and second slot positions to the second number of slots in the frame using a binary distribution tree.
