Appl. No.:

09/285127

Inventors:

Amr A. Awadallah - Stanford CA
Michael Chen - Cupertino CA
David Li - Stanford CA
Manu Thapar - Freemont CA

Assignee:

Nortel Networks Limited - St. Laurent

International Classification:

H04L 1256

US Classification:

370229, 370412, 370465, 709103, 709235, 709244, 713100, 713201

Abstract:

A packet mapper prioritizes streams of data packets in a computer network, each data packet having a packet header containing feature values descriptive of the data packet. The packet mapper includes a mapping table that associates application-related features with network-reserved feature values from a range of feature values reserved for use by selected network data packet streams, and a feature value mapper that performs at least one of (i) in each packet header having an application-related feature value associated with a network-reserved feature value, substituting the associated network-reserved feature value for the application-related feature value, and (ii) in each packet header having a network-reserved feature value associated with an application-related feature value, substituting the associated application-related feature value for the network-reserved feature value.

International Classification:

G06F015/16
H04M015/00

US Classification:

709231, 37911413

Abstract:

A system and method are disclosed in which an initiating caller using a station connected to a data network receives advertisement information while waiting for a call to complete between the station and the receiving party. The station connects with a server that can access a database storing a plurality of advertisement information. The station includes a user interface, which allows the caller to interact with the station, and a flow controller, which monitors the bandwidth available to receive information from the server system.

Appl. No.:

09/584120

Inventors:

Michael C. Chen - San Jose CA, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H04L012/28

US Classification:

370412, 370516, 370519, 370468

Abstract:

A system and method is disclosed for providing dynamic multimedia jitter buffer adjustment for packet-switched networks. The system temporarily stores an amount of incoming data, which is dynamically adjustable, for an amount of time before sending the data out in a more even stream. The system includes a decoder clock, a jitter buffer, a network jitter statistics collector, and a jitter buffer controller. The decoder clock indicates the arrival-time of the data at the system, while the network jitter statistics collector collects the playback-time of that data. By comparing the arrival-time and the playback-time, the jitter buffer controller determines whether the data arrived on schedule. Accordingly, the depth of the jitter buffer can be adjusted to accommodate the late or early arriving data.
