FATHOM(TM) to Provide AGT's Managed Services Division with Ability

to Evaluate Future Video Network Performance for Its Customers

Applied Global Technologies, an innovative technologies company offering reliable and worry-free managed services for IP audio, data and video communications, announces the release of its new network analysis tool - FATHOM(TM). This tool allows AGT to thoroughly evaluate individual networks' capacity and capability to support H.323 video and audio traffic at the desired quality and quantity.

This network services tool may be used to:

-- Pre-engineer a network: Allows one to determine the best

approach prior to rolling out H.323 video within a network so

that organizational goals are realized.

-- Troubleshoot current networks: In cases where users are

reporting problems, this tool provides the data necessary to

isolate the exact cause and determine potential solutions.

-- Prevent potential problems: By systematically monitoring

network QoS under actual conditions, this tool will help to

anticipate and prevent end user problems as network usage

patterns evolve.

The standard utilization of the tool requires deployment of multiple FATHOM(TM) test endpoints onto the customer network. There is no interruption of service during the testing period.

"FATHOM's ability to generate, test and monitor H.323 specific traffic in an operational network setting provides companies considering upgrading to Video over IP a powerful tool to analyze and prepare their converged network," stated Ben Atha, Chief Technical Officer, Applied Global Technologies. "Knowing network parameters prior to video infrastructure changes, eliminates the costly mistakes and ensures that the end-users first Video over IP conference is successful, a key ingredient to technology acceptance."

Providing further detail on its actual operation, FATHOM(TM) creates test video calls between pairs of FATHOM(TM) endpoints. During each test call, the FATHOM(TM) endpoints collect statistics on the packet loss, end-to-end network delay and jitter along the path of the call. Multiple calls are placed between different combinations of endpoints and at various times of the day, to create a clear picture of the manner in which the network operates under actual H.323 loading conditions. The evaluation of actual conditions is unique to the FATHOM(TM) tool. In addition, parameters, such as the video bandwidth and IP TOS flags, may be set at will for each test call. And because FATHOM works within mesh networks by design, it is the only tool that optimizes point-to-point calls as well as MCU calls.

All data is collected from the testing period and a final report is delivered to the customer. The report, combined with analysis by AGT engineers, allows the customer opportunity to maximize its communication objectives and minimize potential end user problems.

"AGT's development of the FATHOM tool was driven by the need for flexibility in selecting the combinations of video codec, bit rate, and traffic prioritization in order to accurately predict the results of a given customer's desired use of video over IP," stated Mark Bearden, Ph.D. "No other H.323 testing tool on the market gives AGT the option of automated testing using full bit rate video test streams."

Bearden is Applied Global Technologies' Lead Engineer on the FATHOM(TM) development. He was closely involved in the recent utilization of FATHOM with a federal customer.
