Teleglobe, INTELSAT to Beta Test First Public Internet 'Push' System

GENEVA--(BUSINESS WIRE)--July 22, 1998--

System Delivers Popular Internet Content via Globeinternet(SM) to Registered Sites

Teleglobe, one of the largest international telecommunications carriers and Internet backbone providers, and INTELSAT, a leading provider of international satellite services, today announced that they will jointly beta test a Multicast Internet Caching and Replication System.

This first commercial implementation of a true "push" system, developed by A&T Systems of Silver Spring, Md., under contract to INTELSAT, will simultaneously deliver the most frequently accessed Internet content to correspondent sites worldwide.

"Push" technology, a growing trend among Internet content providers, sends information automatically to the user, versus content that the user or server must actually seek and retrieve.

The announcement was made during INET, the Internet Society's annual conference, for which Teleglobe is providing 4 Mbps of its Internet access service, Globeinternet(SM), for conference attendees, via its Frankfurt Globeinternet Point of Presence (POP).

In the beta test phase of this development, Teleglobe will operate a content "warehouse," which will be physically operated as a part of one of its INTELSAT earth stations.

Web-based content will be multicast from a hub cache at the warehouse to ISP-operated "kiosks" worldwide, which, in turn, will cache and offer content to local users.

This dual caching architecture is unique because the "push" mode takes advantage of the multicast protocol, versus the more typical "pull" approach used by other caching systems operating in a unicast mode.

In the first release of the system, the warehouse will contain and manage popular pre-selected content, websites wishing to offer their content via the warehouse, and content requested from kiosk operators or users.

Teleglobe, INTELSAT and A&T Systems plan to initiate the beta test in November.

"The marriage of our global Internet backbone service, Globeinternet(SM), with the caching and replication system will allow ISPs and other online providers worldwide to improve service quality and reduce costs by locally hosting popular content," said Bob Collet, vice president and general manager of Teleglobe's data services division.

Teleglobe's NxSTM-1 (Nx155 Mbps) backbone is a Cisco Powered Network, which includes POPs in the United States and Canada, and Europe, via its international transmission infrastructure -- the third largest in the world.

Teleglobe is directly connected to other U.S. backbone networks, other networks by Network Access Points (NAPs) throughout the United States and Europe, and soon to other major content sites.

Teleglobe's Cisco Powered Network status reflects the company's commitment to using industry leading, state-of-the-art technology from Cisco in order to deliver a high level of network interoperability, reliability and performance, as well as new, advanced and differentiated services.

Tom Eaton, vice president of sales and marketing at INTELSAT, said, "INTELSAT is gratified to be working closely with Teleglobe, as well as many other INTELSAT Signatories, to utilize the benefits of satellite-based transmission to bring Internet connectivity to more and more people and places throughout the world.

"Our caching and replication service platform was designed around the natural ability of satellite to multicast data traffic. We believe it can be a true innovation in the global delivery of Internet services, so helping to make the World Wide Web truly worldwide."

Teleglobe is recognized as a world leader in the intercontinental telecommunications industry.

The Teleglobe network includes submarine cable and satellite facilities linking North America with over 240 countries and territories, meeting global connectivity needs of established and emerging carriers from around the world, as well as those of Internet Service Providers (ISPs), multinational corporations and broadcasters.
