US Patent:

6747999, Jun 8, 2004

Filed:

Nov 15, 1999

Appl. No.:

09/440215

Inventors:

Mark Grosberg - Boca Raton FL
Mark Flanagan - Boynton Beach FL
Kristin Butcher - Boynton Beach FL
Jeff Cripe - Lake Worth FL

Assignee:

Siemens Information and Communication Networks, Inc. - Boca Raton FL

International Classification:

H04J 306

US Classification:

370516, 370235

Abstract:

A jitter buffer controller ( ) allows the depth of the jitter buffer ( ) to be adjusted dynamically according to the varying jitter of the current sequence. The jitter buffer controller ( ) maintains a cache ( ) of previous jitter values. This cache contains exponentially averaged values that represent the long-term behavior of specific destinations jitter characteristics, i. e. , a jitter characteristic memory. These values are used to initialize the jitter buffers depth. The jitter cache prevents the buffers depth from being initialized with an arbitrary value that disregards the specific destinations jitter characteristics.

US Classification:

370230, 370235, 370352

Abstract:

During voice-over-Internet-protocol calls, data are gathered about packet loss on the path over the IP network. An algorithm (in the preferred embodiment, the Sliding Window Exponential Average Algorithm) is used to evaluate the packet loss. The Sliding Window Exponential Average Algorithm allows for past performance to be considered along with current performance. If the resulting evaluation fails to meet predetermined criteria, the path over the IP network is blocked and calls are routed over an alternative.

Abstract:

A review facility and review method for interactively reviewing an item, such as a block of code, by a group of reviewers and collecting comments from the reviewers. An author provides the item as text for preparation for interactive review. The text is prepared, tagging each line and making the tagged text available to reviewers, e. g. , as links on a web page. Reviewers interactively comment on individual lines and review previously entered comments. An abbreviated formal review may follow the interactive review.
