Tolly Group Evaluates Ipanema's System V 4.3; Verifies It Can Guarantee Performance of Business-Critical Applications Under All Circumstances.Battery of WAN Lab Tests Using Apdex Performance Metric Show Network Optimization Solution Offers Good to Excellent Quality of Experience CONCORD, Mass. -- Ipanema Technologies, the leader in application traffic management systems for wide-area networks Wide-area networks Communication networks that are regional, nationwide, or worldwide in geographic area, with a minimum distance typical of that between major metropolitan areas. Smaller networks include metropolitan and local-area networks. (WANs), today announced the results of The Tolly Group's evaluation of Ipanema's System. The tests, commissioned by Ipanema, verified that the Ipanema System can guarantee the performance of business-critical applications in WAN environments under all circumstances. Ipanema commissioned The Tolly Group to evaluate its Ipanema System V 4.3 and illustrate its effectiveness in providing desirable and predictable application performance in congested con·gest·ed adj.

Tolly Group engineers subjected the solution to a battery of tests that involved running multiple applications in a simulated headquarters/remote office three-node network. Application performance was benchmarked in both "before" and "after" scenarios. "As businesses deepen their reliance on the Internet and WANs to achieve their critical business objectives, guaranteeing the performance of critical business applications is crucial," said Kevin Tolly - Tolly Group's CEO (1) (Chief Executive Officer) The highest individual in command of an organization. Typically the president of the company, the CEO reports to the Chairman of the Board. and president "These comprehensive tests showed that the Ipanema System can guarantee application performance in congested WAN scenarios even when multiple applications and sites were competing for limited WAN resources." Results were summarized using an estimated MOS (1) (Metal Oxide Semiconductor) See MOSFET. (2) (Mean Opinion Score) The quality of a digitized voice line. It is a subjective measurement that is derived entirely by people listening to the calls and scoring the results from score for VoIP and the Apdex performance metric for all other applications. Apdex is a numerical measure of user satisfaction with the performance of enterprise applications. These metrics are better suited for capturing Quality of Experience (QoE) than traditional response-time metrics and acceleration factor. Testing took place in October 2006. QoE is the subjective notion of satisfaction that end-users have while using different applications. For voice it is the perceived speech quality, for video it is the perceived quality of the image and for other applications it is the expectation of response time for the completion of a task. These expectations are different for different applications. Few are annoyed if an email doesn't arrive immediately; however, the expectation for a transaction task may well be an immediate response. The optimal application performance QoE offers maximum end-user productivity. Multiple test scenarios were run that measured the transaction times of common business critical applications, including VoIP, E-mail (MAPI (Mail API) A programming interface from Microsoft that enables a client application to send to and receive mail from Exchange Server or a Microsoft Mail (MS Mail) messaging system. Microsoft applications such as Outlook, the Exchange client and Microsoft Schedule use MAPI. ), Web browsing (HTTP HTTP in full HyperText Transfer Protocol Standard application-level protocol used for exchanging files on the World Wide Web. HTTP runs on top of the TCP/IP protocol. ), SSH (Secure SHell) A security protocol for logging into a remote server. SSH provides an encrypted session for transferring files and executing server programs. Also serving as a secure client/server connection for applications such as database access and e-mail, SSH supports a transactions and file access (CIFS (Common Internet File System) The file sharing protocol used in Windows. It evolved out of the SMB (Server Message Block) protocol in DOS, which is why the terms CIFS/SMB and SMB/CIFS are sometimes seen. The word "Internet" in the CIFS name has little relevance. ) across a simulated 1 Mbps WAN link (with 50 ms of latency). Also, some non-critical traffic, such as FTP FTP in full file transfer protocol Internet protocol that allows a computer to send files to or receive files from another computer. Like many Internet resources, FTP works by means of a client-server architecture; the user runs client software to connect to and Windows Media Microsoft's audio and video framework for Windows, which embraces playback, encoding and streaming.

Streaming, was used to introduce congestion The condition of a network when there is not enough bandwidth to support the current traffic load. congestion - When the offered load of a data communication path exceeds the capacity. into the WAN link for all the scenarios. Four scenarios were tested three of which included meshed traffic: point-to-point, any-to-any, some-to-any and some-to-any with device free branch office. Tests show that the Ipanema System guarantees the performance of business-critical applications by maintaining Good to Excellent Apdex scores (mostly excellent) for all the business-critical applications across the range of scenarios tested. In ever more complex scenarios, the Ipanema System improved the performance of critical applications and delivered an excellent end-user QoE. Finally, even without a device in a branch office, the Ipanema System, using its Cooperative Tele-Optimization feature, improved the performance of critical applications and provided an acceptable end-user QoE. "The excellent QoE delivered by the Ipanema System is the result of three unique key characteristics of Ipanema's Optimization: Ipanema optimization is dynamic, objective based, and global. Today Ipanema is the only system on the market capable of delivering performance guarantees for critical applications 100% of the time in even the most difficult network conditions," said Vargha Moayed Executive Vice President of Ipanema. "We congratulate Ipanema and The Tolly Group for using the Application Performance Index (Apdex) in their comprehensive testing," said Peter Sevcik, president of the Apdex Alliance and NetForecast. "Apdex measures user satisfaction of enterprise application performance, helping firms gauge the effectiveness of their IT investments and understand whether their applications are delivering on promises. End user organizations can be assured that results as determined by Apdex will accurately reflect the user experience."
