US Patent:

7817567, Oct 19, 2010

Filed:

Jul 28, 2003

Appl. No.:

10/627619

Inventors:

William Grant Grovenburg - Monument CO, US

Assignee:

JDS Uniphase Corporation - Milpitas CA

International Classification:

H04J 1/16

US Classification:

370252, 709224

Abstract:

Network analyzers (NAs) monitor respectively corresponding communication lines through which Voice over Internet Protocol (VOIP) data streams are transmitted. A network troubleshooting center (NTC) communicates with the NAs to provide quality of service statistics for data streams transmitted through the communication lines and associated with a respective telephone call.

Appl. No.:

10/263903

Inventors:

William Grant Grovenburg - Monument CO, US

Assignee:

JDS Uniphase Corporation - Milpitas CA

International Classification:

G01R 31/08

US Classification:

370252, 370242

Abstract:

An apparatus and method monitor RTP streams between first and second endpoints within a network. A network analyzer is connected at an intermediate point between the first and second endpoints within the network, to extract and process data from RTCP packets to select and monitor the RTP streams accumulated therein having a worst-case jitter and packet loss within the network.

International Classification:

G06F 15/173
H04L 12/66
H04M 1/64

US Classification:

709224, 370352, 379 8817

Abstract:

The communication apparatus includes a VoIP phone, a VoIP gateway, a communication network, and a network analyzer. The VoIP phone is a transmitting/receiving device to transmit and receive a VoIP phone call. A plurality of VoIP phone calls are transmitted and received over the communication network via the VoIP gateway. The network analyzer analyzes and monitors the plurality of VoIP phone calls transmitted and received over the communication network. Accordingly, a respective VoIP phone call is identified from the plurality of phone calls and associated with a respective data stream to be monitored and analyzed by the network analyzer.

Appl. No.:

10/263783

Inventors:

William Grovenburg - Monument CO, US

International Classification:

H04J003/06
H04L012/28
H04L012/66

US Classification:

370/350000, 370/395210, 370/352000

Abstract:

An apparatus and method calculate a round-trip delay (RTD) between first and second endpoints within a network, where an intermediate point is selected between the first and second endpoints within the network. A network analyzer determines a first data transmission time from the intermediate point to the first endpoint and back to the intermediate point, determines a second data transmission time from the intermediate point to the second endpoint and back to the intermediate point, and adds the first and second data transmission times to determine therefrom the round trip delay between the first and second endpoints within the network.
