Dyband Delivers Intelligent IP Traffic Management for Satellite Access

OTTAWA, ONTARIO, CANADA (August 6, 2002)-Dyband, a supplier of IP traffic management solutions to service providers and enterprises worldwide, today announced delivery of the first IP traffic management solution that delivers effective quality-of-service for satellite access.

Dyband monitors and controls bandwidth usage and manages SLAs in broadband satellite access environments, including residential Internet access; enterprise Internet access and Intranet/LAN/WAN connectivity; air, land, and maritime mobile access; and ISP backbone access-satellite connections between remote ISP POPs and the Internet backbone, which are primarily for service providers in developing countries and remote regions.

"Dyband is one of the key components in our network," said Mario Pino, president of Internet Satellite Platform Inc. (ISAT), a Florida-based company that provides wholesale "last mile" connectivity via satellite to Internet service providers throughout North and South America. "It allows us to get the most throughput from our satellite uplink and to provide our customers with the service level they pay for. With Dyband, we can load the network properly so that every customer in the platform has a great experience."

"We are offering Dyband traffic management software as part of every IP-based satellite datacasting solution we sell," stated Gary Carter, vice president of sales and business development at International Datacasting, an Ottawa-based corporation providing advanced products, systems and services for broadband wireless infrastructure networks used to distribute multimedia data. "In order to effectively utilize DVB IP systems today, customers need QoS, and we have found the Dyband product to be excellent."

"The focus of most satellite players has shifted to include two-way broadband local loop access and complex, end-to-end content distribution solutions," stated Christopher Baugh, founder and principal analyst of Northern Sky Research, an international market research and consulting firm specializing in broadband technology and Internet applications. "These applications demand new solutions that are technically sound, easy to implement and scale with demand."

THE DYBAND SATELLITE SOLUTION

Dyband intelligent IP traffic management software enables satellite service providers to tightly control bandwidth consumption, by IP address, for up to 50,000 individual satellite subscribers and/or groups (per unit), define and manage a virtually unlimited number of SLAs at distinct price points; and view and adjust network performance in real-time, while gathering comprehensive historical statistics for later analysis.

MEETING SATELLITE'S CHALLENGES

"Dyband meets several key financial and technical challenges facing satellite service providers today," stated Tim Welch, president and CEO of Dyband Corporation. "And it provides a rapid return on investment."

Dyband maximizes throughput across the satellite link.

Dyband manages IP traffic dynamically, evaluating traffic conditions at every node in the distribution network 100 times per second. When congestion is detected (when bandwidth demand outstrips capacity), transfer rates are immediately restricted in the affected areas. When congestion is relieved, transfer rates return immediately to normal limits. By assessing and responding to traffic conditions in real time, Dyband makes full use of available satellite bandwidth.

Dyband also enhances the efficiency of the Internet connection by reducing packet loss. By providing subscribers with equitable access to bandwidth through its system of dynamic priorities, Dyband achieves a reduction in retransmission requests and thus reduces packet loss at upstream routers.

Dyband shapes traffic independently of the latency of the medium.

Dyband evaluates and shapes traffic every 10 ms, regardless of the inherent latency of the Internet connection. This is a significant benefit for satellite providers, where the average propagation delay is considerable-500 milliseconds per round-trip.

Dyband manages both unidirectional and bi-directional traffic.

Dyband offers complete flexibility in managing upstream and downstream traffic by providing separate controls for each traffic direction. For a satellite provider, this means that a single Dyband software solution can manage its IP traffic even if the nature of its distribution network (unidirectional vs. bi-directional) changes over time or from one service area to another.

Dyband provides insight into the satellite distribution network.

Dyband delivers insight into both the topology and performance of the satellite distribution network. For each managed point in the network (i.e., individual subscribers, groups, gateways, or subnets), Dyband provides real-time statistics that allow service providers to make immediate SLA adjustments and create extensive, customized historical reports for capacity planning, timely provisioning, usage-based billing, and customer support.

DYBAND AVAILABILITY

Dyband is available today and operating in satellite access environments. Dyband intelligent IP traffic management software is easy to install and runs on industry-standard hardware platforms and operating systems. The software is available in a broad range of configurations that scale to meet the needs of satellite service providers as they grow-from 1 Mbps to 100 Mbps of managed bandwidth per Dyband unit, easily handling a full transponder.
