Filed:

May 1, 2006

Appl. No.:

11/415831

Inventors:

Christopher W. Hamilton - Breinigsville PA, US
Noy C. Kucuk - Calgary, CA
Jinhui Li - Macungie PA, US

Assignee:

Agere Systems Inc. - Allentown PA

International Classification:

H04L 12/54

US Classification:

370429, 370235, 3703954, 370412, 370428

Abstract:

A scheduler is adapted to schedule packets or other data blocks for transmission from a plurality of transmission elements in timeslots in a communication system. The scheduler determines scaled capacity measures for respective ones of the transmission elements, with each of the scaled capacity measures being scaled by a combination of a waiting time and an occupancy for a corresponding one of the transmission elements. The scheduler selects one or more of the transmission elements for scheduling in a given one of the timeslots based on the scaled capacity measures. The scheduler in an illustrative embodiment may be implemented in a network processor integrated circuit or other processing device of the communication system.

Christopher W. Hamilton - Breinigsville PA, US
James Mark Sepko - Coplay PA, US

Assignee:

Agere Systems Inc. - Allentown PA

International Classification:

H04L 12/56
H04J 3/26

US Classification:

370390, 370400, 370432, 370469

Abstract:

A network-based data distribution system includes a physical layer device connectable to a network processor operative in a link layer or higher layer. The physical layer device is configurable for interfacing with a plurality of destination devices via corresponding physical layer links. The physical layer device is operative to receive data traffic from the network processor and to replicate at least a portion of the data traffic at a physical layer for distribution to at least two of the plurality of destination devices associated with the physical layer links.

Inventors:

William R. Bullman - Macungie PA, US
Christopher W. Hamilton - Breinigsville PA, US

Assignee:

Agere Systems Inc. - Allentown PA

International Classification:

H04L 12/28

US Classification:

370392, 370401

Abstract:

Voice services are provided in a network node of a digital networking system. A service signal is provided to at least one user device. One or more voice packets are received from the at least one user device. The one or more voice packets are processed, and transmitted to one or more destinations determined in the packet processing.

Assignee:

Agere Systems Inc. - Allentown PA

International Classification:

H04N 7/173

US Classification:

725 94, 725 86, 725 87, 725 90, 725 91, 725 93, 725 95, 725 96, 725 97

Abstract:

Apparatus for distributing streaming multimedia to at least one end client over a network includes memory and at least one processor operatively connected to the memory. The processor is operative: (i) to receive the streaming multimedia from at least one multimedia source via at least one of a plurality of channels in the network; (ii) when a channel change request generated by the end client for changing a channel and corresponding multimedia content from the multimedia source is not detected, to deliver the at least one multimedia stream to the end client at a first data rate; and (iii) when the channel change request has been detected, to deliver the at least one multimedia stream to the end client at a second rate for a prescribed period of time after receiving the channel change request and, after the prescribed period of time, to deliver the at least one multimedia stream to the end client at the first data rate, wherein the second data rate is greater than the first data rate.

Assignee:

Agere Systems Inc. - Allentown PA

International Classification:

H04L 12/56

US Classification:

Abstract:

A scheduler is adapted to schedule packets or other data blocks for transmission from a plurality of transmission elements in timeslots of a frame in a communication system. In scheduling for a given frame, the scheduler initially designates each of the transmission elements as eligible to transmit one or more data blocks in the given frame, and selects from among those of the transmission elements designated as eligible at least one of the transmission elements for scheduling in a next available timeslot of the given frame. The scheduler then adjusts the eligibility status of the selected transmission element(s), and repeats the selecting and adjusting operations for one or more remaining timeslots of the given frame. The scheduler in an illustrative embodiment may be implemented in a network processor integrated circuit or other processing device of the communication system.
