OTTAWA, ONTARIO, CANADA (April 13, 2004)-Dyband, a supplier of IP traffic management solutions to government, enterprises and service providers worldwide, today announced the availability of its newest version of its intelligent IP traffic management solution. Version 2.2 of the Dyband IP Traffic Management software adds important functionality that further simplifies management, increases usability and adds increased visibility into the Shaper software. Version 2.2 also provides greater choice of modern OS platforms and processor support.

DYBAND MAKES YOUR NET WORK

Dyband's IP Traffic Management solution makes your net work for you, providing unique value to your business in three ways:

• Control costs by managing precisely who gets how much bandwidth and when, enabling you to add 30% more users to your network connection without adding additional bandwidth, while improving your overall quality of service,
• Gain visibility in real time into your network performance, from a high level right down to the individual user, as well as historical statistical information that you can use for analysis, capacity planning and connecting to billing systems,
• Increase revenues for service providers by adding more customers to your internet backbone than without Dyband, and for governments and enterprise by ensuring the smooth and predictable flow of information over your network, enabling your users to focus on your core business.

THE DYBAND SOLUTION

Dyband's IP Traffic Management solution enables its customers to control bandwidth consumption, by IP address, for up to 50,000 managed points-individual subscribers, groups, subnets, and/or gateways. Multiple allocation schemes (guaranteed, preferred, equitable, etc.) distribute available bandwidth across all managed points during both normal and congested conditions. By evaluating the bandwidth capacity/demand ratio 100 times per second, Dyband can dynamically shape individual and aggregate bandwidth usage based on traffic conditions, minimizing network congestion, reducing packet loss, and optimizing Internet backbone utilization. The software also allows access providers to define and manage a virtually unlimited number of SLAs at distinct price points. And, it enables new visibility into bandwidth consumption, allowing operators to make real-time usage decisions, and gather comprehensive historical statistics for later analysis.

NEW FEATURES IN VERSION 2.2

"We have added some important customer-requested features in this release that will improve our already easy management interface and Shaper functionality" said Walter Capitani, head of Software Engineering at Dyband. "Our new autodiscovery feature, Shaper event logging and other key features add to the overall usability of Dyband within a variety of access networks."

Dyband is also announcing support of the newest Microsoft Windows operating systems, Windows XP Professional and Windows Server 2003, as well as a new automated licensing system that will speed the delivery of the product to customers.

"I am particularly pleased to announce the launch of the Dyband Knowledge Base", continued Mr. Capitani, "which will provide all of our customers and prospects useful information on policy and profile configuration, shaper operation, and maintenance. The Dyband KB is a powerful resource available 24/7 for our customers to ensure they have the most recent information on the use and management of the Dyband software."
