FOUNDRY NETWORKS DEMONSTRATES LAYER 4-7 SWITCHING USING MICROSOFT'S WINDOWS
STREAMING MEDIA SOLUTION

Foundry Gigabit Ethernet Switches Recommended by Microsoft for Video on Demand

Sunnyvale, CA - November 1, 1999 - Foundry Networks, Inc. (NASDAQ: FDRY) and Microsoft are demonstrating Foundry's ServerIron switch and Microsoft's Broadband Windows Streaming Media for Internet video on demand services in
Microsoft's Partner Solutions Center in Redmond, WA. The combined solution is targeted to ISPs, cable and wireless companies and CLECs. Tasked with creating and testing a multi-gigabit Video Server Farm, the Microsoft Partner Solutions Center worked with Foundry to provide the critical network element of its Windows Streaming Media solution. The
Microsoft Partner Solutions Center is using Foundry's ServerIron switches - for its server load balancing, symmetric server load balancing and direct server return features.
"We especially like the Internet IronWare features of Foundry's ServerIron switch, specifically the direct server return and symmetric server load balancing," said Steve Nielsen, Microsoft Network Specialist. Direct server return supports up to 1,000,000 concurrent active user connections and enables requested content to be served through the best return path. This significantly improves the service performance provided
to end-users and allows system performance to scale based on the requirements of applications such as streaming media, web pages and graphics. The symmetric server load balancing features provide up to 2,000,000 connections and full service redundancy to mission critical services such as video streaming on demand. "The Foundry Networks solution is a highly scalable and available solution that adds considerable value to our overall Broadband Windows Streaming Media Solution," added Nielsen.

FOUNDRY NETWORKS'
SERVERIRON SWITCHES 
SUPPORT THE WEB SITE OF THE 
WEATHER CHANNEL
THROUGH STORMY WEATHER

Sunnyvale, CA - October 4, 1999 -U.S. residents anxious for real time information about Hurricane Floyd and Tropical Storm Hillary logged onto The Weather Channel web site, weather.com, in record numbers last week. weather.com was able to take the deluge of traffic in stride, with the support of an installed base of Foundry Networks' ServerIron switches that load balance web server farm traffic at Gigabit speeds. "We rely on our network to withstand the heavy traffic our site receives during severe and breaking weather. That is why it is imperative to have server load balancing switches that provide not just great performance, but high reliability," said Marc Froemelt, Director of Site Architecture at The Weather Channel.

weather.com announced a record high in web site hits during the storms a couple of weeks ago, receiving a surge of 23.5 million page views, nearly doubling the site's previous record of 12.6 million hits set in September 1998 during coverage of Hurricane Georges.

"We put Foundry's ServerIron and TurboIron/8 server load balancers in our web site co-locations in San Francisco, California (Exodus) and Reston, Virginia (Cable & Wireless) last year, and they have consistently supported our traffic loads during critical service periods such as the one we just experienced with Hurricane Floyd," continued Froemelt.

According to Media Metrix, weather.com is continually ranked as one of the top single content sites, reaching 8.3 percent of the total web audience. weather.com consistently averages more than 130 million page views per month, offering users up-to-the-minute national and local forecasts as well as special feature content for business professionals, sports and outdoor enthusiasts. It is visited by 11.5 percent of those who access the Internet while at work and 5.4 percent of all home users, providing consumers with a one-stop location to receive all their weather, travel and leisure information.

"We chose Foundry because initially, they were the only company able to deliver server load balancing switches at Gigabit Ethernet speeds. We also evaluated Alteon Web Systems, and F5Labs, but Foundry offered superior price/performance and fail-safe features," added Froemelt.

With ServerIron's Internet IronWare server load balancing capabilities, server resiliency and performance are increased. The ServerIron switch increases performance by load balancing traffic, based on a variety of user defined metrics, among multiple servers. ServerIron ensures service availability by offering features such as switch, server, link and session level redundancy.
