SANTA CLARA, CA -- Peribit Networks, the only developer of DNA sequencing-based network bandwidth optimization products, and The Tolly Group, the IT industry's leading performance testing and analysis organization, today announced the results of tests performed on Peribit's SR-50 Sequence Reducer product. The results, published today, reveal wide area network (WAN) bandwidth capacity gains of as much as 29 times over traditional T-1 link capacity limits. Peribit's SR-50 product is a LAN-based network infrastructure device that uses Molecular Sequence Reduction (MSR) technology to identify and eliminate repetitive data before that data traverses costly WAN links. Testing was performed in August and October of 2001. Tolly researchers discovered that Peribit's SR-50 product produced WAN capacity gains of more than four-times the physical link capacity, and in some cases as much as 29 times that of the established baseline bandwidth. Testing also revealed that the SR-50 performs these reduction rates across a rich mix of all types of IP traffic within enterprise networks, including e-mail, database, video, web, and domain name server (DNS) traffic types. Tests coupled multiple Peribit SR-50 products with various networking equipment products to create a live data network functionally representative of many Fortune 1,000 company environments. "The cost of T-3, T-1 and sub-T-1 links today makes it imperative that enterprises optimize the use of those WAN circuits to get the most bang for the buck," said Kevin Tolly, president and CEO of The Tolly Group. "Our testing shows that Peribit has developed a technology that instantly delivers a dramatic capacity gain to wide area networks." "The Tolly Group subjected Peribit's SR-50 Sequence Reducer product to a battery of tests involving HTTP, HTTPS, FTP, POP3, database and other types of transactions," said Tolly. "When engineers saturated the link with these transactions, the SR-50 more than quadrupled the effective throughput of that link. And, in an extreme-case file-transfer scenario, Tolly Group engineers saw link-wide effective throughput increase up to 29 times over a single T-1. In addition, engineers found that the SR-50 works on all IP traffic, regardless of application, and provided significant link-wide reduction rates across all test iterations at link speeds up to and including T-3." Tolly Group engineers revealed the following results from their extensive testing: -- A pair of SR-50s connected via a simulated T-1 supporting mixed-traffic flows delivered an effective throughput of 5.5 Mbit/s or 4.2 times more data than supported over the WAN link without the Peribit SR-50 device. It reduced the amount of data flowing across the T-1 link by 81.2%; -- When tested in the presence of files containing many repeated character strings, the SR-50 delivered effective throughput equal to 44 Mbit/s, or 29 times more data than supported over the T-1 without the SR-50; -- When tested with pre-compressed Advanced Streaming Format (ASF) video files, the SR-50 delivered 18.65 Mbit/s of effective throughput across the simulated T-1, or more than 12 times the throughput supported across the link without the SR-50; -- When a pair of SR-50s were tested in a simulated Quad T-1 and in a T-3 configuration, results show that the SR-50s achieved an average traffic reduction of 95% and 95.7% respectively, with mixed traffic types contending for WAN bandwidth. Testing also revealed that the SR-50 maintains non-stop network data flow under all conditions -- even during a power loss. Tolly researchers found that with traffic active on the network and a simulated power failure induced, the traffic continued to traverse the network. In a variety of test scenarios, SR-50s were constantly flushed with new traffic types to determine how the units respond to dynamically varying traffic. During the testing, a mix of traffic streams, such as ASCII, executables, encrypted and pre-compressed data streams were used to evaluate performance in a "real-world" environment. The results prove that the SR-50 produces a substantial net benefit over a wide variety of IP traffic, and underscores the fact that using MSR across WAN links, even relatively fast T-3 links, is extremely effective. This improved efficiency of WAN links using MSR can immediately increase link bandwidth while substantially reducing the cost of WAN circuits. "IT directors and network managers today face a quandary -- how to accommodate growing network traffic while at the same time reducing IT expenses," said Jef Graham, president and CEO of Peribit Networks. "Peribit delivers immediate WAN pain relief to IT management that effectively cleanses their network infrastructure of repetitive data that has previously consumed costly WAN bandwidth. The gains are so dramatic that the SR-50 literally pays for itself in months, meaning that even in these budget constrained times, companies can increase network performance and save money." Molecular Sequence Reduction and the SR-50 Peribit's SR-50 is the first and only product that harnesses the principles used in the mapping of DNA to drastically improve IT efficiency. The product is based on the company's MSR technology, which leverages the repetitive sequence analysis techniques used to examine DNA patterns in computational molecular biology to identify and eliminate data flow and pattern similarities over wide area networks. As a result of this unique technology, Peribit has found that between 70% and 90% of WAN capacity is littered with useless, repetitive data. These repetitions waste valuable network resources and severely degrade network efficiency and application performance. By identifying, and then eliminating repetitions, Peribit's Sequence Reduction products allow enterprises to harness drastic increases in network capacity over their existing network infrastructure while improving application performance and reducing IT costs. Peribit's Molecular Sequence Reduction is also the only technology that operates on all traffic that traverses the network -- any application, content, protocol or transmission technology.
