SkyCache Announces Compatibility with Inktomi's Traffic Server... ... ISPs and Backbone Providers Gain a Competitive Edge Through Combination of Satellite Broadcasting and Caching

Laurel, MD. - September 21, 1998 - SkyCache^tm, Inc., the pioneer in Internet satellite datacasting and Inktomi Corp. (NASDAQ: INKT), leading developer of scalable Internet infrastructure software, announced that Inktomi's Traffic Server^tm network cache has been certified for compatibility with the SkyCache network. SkyCache customers will now be able to deploy the market's leading carrier class cache solution to improve the performance and efficiency of their networks.

"Inktomi's Traffic Server, because of its high performance and robust management capabilities, is an excellent solution for carrier-class customers," stated Doug Humphrey, president and CEO of SkyCache. "As audio/video streaming and other new protocols emerge on the Internet, Traffic Server's scalability and flexible software design make Inktomi a key strategic complement to SkyCache's satellite broadcast model."

The SkyCache service uses satellite broadcast technology to constantly load the most often requested Web and news traffic directly into customer-side ICP-compliant cache systems. By virtue of being a true broadcast mechanism to deliver data, SkyCache solves updating and communications problems across distributed caching systems implemented by Tier 1 ISPs and enterprises. Since all caches are constantly and directly refreshed with the most frequently accessed Internet content via satellite, terrestrial leased line bandwidth and user performance are not affected by cache updating activity.

Inktomi's Traffic Server is a carrier-class network cache designed to help Internet infrastructure providers scale up their operations to meet rapidly growing demand and performance requirements. Based on Inktomi's innovative cluster and parallel computing technologies, Traffic Server provides incremental and absolute scalability as well as the ability to easily manage large cache systems as a single unit. By embedding programmable intelligence into the network, Traffic Server provides a platform for ISPs, backbone providers, and hosting providers to deliver value added services to their customers.

"SkyCache has shown tremendous innovation and leadership in the satellite broadcast space," said Paul Gauthier, co-founder and chief technology officer of Inktomi. "We look forward to working with the SkyCache team to bring competitive advantage and advanced services to our mutual customers."
