Netli Unveils World's First Application Delivery Network Netli (netli.com) today unveiled a reliable, easy to adopt Internet optimization service that improves the performance of enterprise-class Web site traffic. The service, entitled NetLightning, is the first application delivery network (ADN) service that transparently provides global sub-second response times for Web applications in a centralized data center. The service requires no changes to site content, servers or client software, or investment in expensive, complex networking technology. The objective of Netli's patent pending technology is to address network latency problems caused by the inherit architecture of the Web. Because the Internet was never designed to support Web applications, the architecture often proves quite inefficient. The farther a user is from an application server, the worse the performance. The problem, known as distance-induced delay, is caused by the combination of geographic distance, the performance of the Internet protocols, and packet loss and congestion within the Internet. Existing Internet performance technologies such as caching, content delivery, and smart routing do not adequately address the performance requirements of dynamic, Web-based applications. Netli's service optimizes all traffic that is delivered by Web (HTTP) servers. This includes all types of dynamic content: database generated, personalized, query responses, and interactive application services. By so doing, NetLightning eliminates distance-induced delay, giving globally distributed users similar Web application performance and availability, as users would experience on a local area network. "What we do is solve response time and availability problems for applications," said John K. Peters, CEO of Netli. "Netli focuses on reducing the multiple TCP connections that need to be opened in order to reduce response time." The service achieves the increase in performance and response time by leveraging Netli's Reliable Application Platform for Instant Delivery (RAPID) service architecture. The platform is comprised of a series of globally distributed virtual data centers and application access points, global DNS redirection and IP address mapping system, high-performance transport protocol and content optimization software, and a 24x7 network operations center. Customers subscribe to the NetLightning service for one or more Web applications, determine the appropriate type and location of the application access point based on their peak end-user demand and location of their applications. The clients delegate to Netli the DNS processing for those applications. When an end-user accesses a Web application, the end-user's browser is transparently redirected to the nearest virtual data center. Netli has strategically deployed 13 virtual data centers in major Internet user population centers around the world. The Web application request arrives at the virtual data center as standard HTTP/TCP traffic, and is then converted to Netli's transport protocol, which is optimized for Web application traffic exchange over the long-haul segments of the Internet. Netli software at the application access point converts the optimized protocols back to standard HTTP/TCP for the final, short connection to the customer's Web application server(s). The process is bi-directional; the returned data stream is optimized by the application access point software and is then transported across the Internet to the virtual data center closest to the end-user. The Netli service thereby reduces the number of "hops" or routes that data upon the Internet needs to traverse in order to be delivered in a timely fashion. "Our technology does not store applications at the edge of the network as content delivery networks do," states Peters. "Our technology accelerates the response of the existing server infrastructure." For this reason, the service is well suited to corporations needing to increase their response times between geographically dispersed sites. The use of Netli software allows specifically designated access points to enhance their network speed. Prominent companies such as HP and Nielsen/NetRating have thus adopted the software. HP is currently using the service to enhance a support portal. The availability and performance of the portal is critical to the productivity of HP's developer community. However, overseas users were experiencing long download times, up to five seconds in Europe and up to nine seconds in Asia. Developers complained to HP's European and Asia Pacific offices that the system was slow, inconvenient and difficult to use. Monthly satisfaction surveys of developers showed the delays were straining the developer and partner relationships. HP turned to Netli and realized immediate and dramatic results, including: consistent sub-second response times measured from Atlanta, San Francisco, London, and Tokyo; significant increase in partner satisfaction through the complete elimination of poor Web application performance, the number one complaint from the developer community; and avoidance of hundreds of thousands of dollars in data center build-outs and data replication solutions. In the case of NetRating, the Internet and digital media measurement and analysis firm required a comprehensive technology solution that would accelerate application performance while permitting the transmission of enormous amounts of data. The company wanted to protect and increase its revenue stream without spending millions on building and staffing new data centers. Utilizing Netli technology, NetRatings was able to increase global sub-second response time for their real-time, online measurement databases without a capital outlay. By utilizing Netli technology, the company realized a $5 million savings over three years, as the deployment of NetLightning allowed NetRating to cancel its plans for duplicate data centers in New York and Europe, the alternative method they would have employed into increase response times. Netli can also be deployed to enhance response time for broadband providers. Peters suggests that the service can be used by Asian or European DSL or cable providers, in order to speed access to search portal sites. Peters also notes that Web hosting providers can leverage Netli as a revenue opportunity by marketing and reselling the service to high-end clients. Pricing for the service starts at about $7,000 a month. A typical customer implementation costs between $10,000 - $15,000 per application. |
