Bytemobile Optimization Services Node (OSN) Enables ISPs to Boost Dial-Up Performance

New Network Node to Debut at ISPCON with Broadband Speeds Delivered Over Dial-Up Networks.

MOUNTAIN VIEW, California - October 6, 2003

Bytemobile, Inc., the company that enables dramatic improvements in both the mobile and remote dial-up data user experience, today announced it will demonstrate its 2.0 Optimization Services Node (OSN) for use in ISP networks at the ISPCON 2003 show in Santa Clara, California on October 20. The carrier-grade platform, which is available now, offers speed increases of up to 10X compared to unoptimized networks, significantly improving web browsing and email for dial-up subscribers.

"Very high speed data performance is becoming increasingly important to dial-up users," says Steve Livingston, Bytemobile's executive vice president of sales and marketing. "Our OSN lets ISPs offer their dial-up subscribers a DSL-like experience for web downloads and email."

Livingston adds, "Our entrée into the ISP market is a natural extension of our success with wireless carriers. We've delivered the market-leading optimization solution to folks like Sprint, Vodafone and Nextel, all backed by worldwide sales and support organizations."

The 2.0 OSN for ISPs is deployed in a client-server model. Based on Bytemobile's proprietary Macara Dynamic Optimization Technology, the solution comprises a suite of advanced approaches to classification, data reduction, intelligent caching and protocol acceleration that significantly improves dial-up performance. With the 2.0 OSN in an ISP's network, subscribers' data flows are optimized for enriched web and email traffic and accelerated data rates of up to 10X.

"A key breakthrough for us in our 2.0 OSN release is our Dynamic Interleaving™ technology," comments David Nowicki, Bytemobile senior director for product marketing and management. "It's a proprietary approach we've developed that virtually eliminates the effects of latency in web browsing. By consolidating, reordering and overlapping data requests and responses, Dynamic Interleaving makes web download times essentially independent of network round-trip time, web-server delays and other common Internet latencies. The benefit to end users is much faster and more consistent data rates — DSL-like rates, in fact."

The Bytemobile optimization solution comes at a time when ISPs are facing high levels of churn to broadband services and increasing price pressure. "Tens of millions of dollars are being lost monthly by ISPs from subscriber churn to either broadband services or lower-priced dial-up providers," says Daniel Torras, director of the Business Strategies Group at Pyramid Research. "It is critical that ISPs improve delivery speeds to keep subscribers, quell churn, and even improve subscriber gains. Optimization in the core network gives ISPs a viable competitive advantage in traditional dial-up networks."

Bytemobile will demonstrate the 2.0 OSN in booth 114 at the ISPCON show.

Bytemobile's OSN products have been widely deployed in mobile operator networks around the globe. The solution is highly scalable and easily deployed in networks supporting large numbers of subscribers.
