Teleglobe Achieves Success With Internet Delivery System Trials.

GENEVA--(BUSINESS WIRE)--Oct. 10, 1999--

Four European "Kiosk" Sites Now Receiving Web Content

Transmissions in Test of World's Only Push-Oriented Multicast

Caching and Replication System

Teleglobe, one of the world's largest global Internet backbone network providers, has achieved success in field trials of the world's first push-oriented multicast caching and replication system. The Internet Delivery System (IDS), designed and developed jointly between INTELSAT and Orblynx, is designed to cache the most frequently accessed Internet content in a data "warehouse" and multicast the content via satellite to multiple Internet Service Provider (ISP) "kiosk" sites around the world. The kiosk sites then deliver the Internet content to local end-users.

By having a single "warehouse" frequently crawl the web to prefetch and push the content to downstream kiosk caches over a multicast path, the IDS assures content freshness, reduces backbone connectivity costs and eliminates end user dependence on origin servers that are susceptible to content unavailability due to "flash" crowds. Announcement of a commercial version of IDS is expected following the completion of field trials.

Kiosk sites in France, Sweden, Switzerland and the United Kingdom, as well as Teleglobe's own facilities in Canada, have been activated and are receiving web content streams from the warehouse via multicast satellite transmissions. Other sites are expected to complete deployment this month. Participants in the trials include British Telecom (NYSE: BTY), COMSAT (NYSE: CQ), Embratel (NYSE: EMT), France Telecom (NYSE: FTE), KPN International, Swisscom (NYSE: SCM), Telecom Authority of Cyprus/CYTANET, Telecom Egypt/IDSC and Telia.

The announcement was made at the Telecom `99 Show in Geneva, Switzerland.

"We are encouraged by the progress achieved with IDS, and are very pleased with the system's functionality and robustness," said Bob Collet, vice president and general manager, Internet and Data Services, Teleglobe Communications Corporation. "These trials are demonstrating that the world's first push-oriented multicast caching and replication system for Internet content works on an intercontinental level. Now that the system is operational in a beta version, we expect to commercially launch IDS on a global scale in the very near future."

Teleglobe plans to offer additional IDS delivery options via: 1) traditional point-to-point satellite links, 2) the company's new DVB/IP satellite service, and 3) the company's terrestrial multicast-enabled Internet backbone network.

In the trials, Teleglobe is operating the data warehouse at one of its sites in Montreal. Internet content is being multicast from a primary cache at the warehouse through Teleglobe's Des Laurentides earth station to multiple ISP kiosk sites around the world over the INTELSAT 603 satellite at 335.5(0)E. These kiosk sites then receive content to be stored in local cache engines on either a "push" (proactive) or "pull" (user-request) basis. Finally, content on the local cache engines is accessed by local ISPs and/or end users. One of the key features of IDS is the ability of the data warehouse to ensure content freshness by prefetching Internet content from content servers when the system determines: a) the frequency at which the content changes, and b) the popularity of the content according to aggregated hit and miss statistics measured from the multiple kiosk sites.

Teleglobe owns and operates one of the world's largest Internet backbone networks, connecting hundreds of ISPs in over 100 countries as well as many content providers and search engines.
