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.

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.

An improved method, apparatus and computer system for automatically reporting of faults in a telephonic network is described. When a network fault is detected, a determination is made by a fault analyzer whether or not the detected fault is a reportable fault. If the detected fault is a reportable fault, then an alarm report based upon the reportable fault is generated which is then distributed based upon a distribution list. The distribution list includes only those destination addresses associated with the reportable fault. The alarm report in distributed to any number and kind of communications devices such as, a pager, an email server, and a control console.

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 destination's jitter characteristics, i.e., a jitter characteristic memory. These values are used to initialize the jitter buffer's depth. The jitter cache prevents the buffer's depth from being initialized with an arbitrary value that disregards the specific destination's jitter characteristics.
