Network Device Reduces Traffic

Software upgrade enables the company's Sequence Reducer to spot redundancies and save bandwidth.

Peribit Networks Inc. last week introduced a software update to a device that it says makes it easier to manage network quality of service and reduce the amount of bandwidth needed to run applications such as voice over IP. The enhanced MSR (Molecular Sequence Reduction) technology in the companys SR-50 network management device uses DNA sequencing-based technology to spot repeated data patterns in traffic from a range of applications. It use that information to reduce the number of bytes and packets traveling on a WAN, officials said. Peribit also said it was adding a second device to its product lineup in September, the SR-55 Sequence Reducer, which adds support for Gigabit Ethernet.
The upgraded MSR technology provides support for QOS, allowing for traffic prioritization both from within the network devices or from other routers or switches on the network. It also adds more powerful reduction capabilities, particularly for VOIP applications. While the technology before could reduce the number of voice bytes by about 15 percent, the MSR upgrade bolsters that to about 40 percent, said Amit Singh, founder and chief technology officer at Peribit.
"As we go into larger accounts, we need these additional features and capabilities to make deployments in complex networks completely seamless," said Singh, in Santa Clara, Calif. Patrick Wilson, director of IT at Finisar Corp., is using the SR-50 in four of his companys five locations to help free up WAN bandwidth. He is planning to add the fifth office later this month. He plans on using the QOS capabilities to gain more granular prioritization than the QOS features provided in his network routers. He also expects the SR-50 to help him avoid having to buy large amounts of new WAN capacity as the fiber optics components maker begins to deploy VOIP applications later this year. "It continues to allow us to add applications without the constant concern of adding bandwidth for every single one," Wilson said. "It makes it more cost effective every time you do something like [VOIP]." The Peribit devices support WAN connections as high as T3 speeds and for applications such as enterprise resource planning systems can reduce data by as much as 75 percent, Singh said. The MSR technology recognizes repeated data patterns – such as one e-mail sent to multiple people, the same database fields or common company information – and only sends one instance of the information over the WAN. It then rebuilds the multiple instances on the other end, Singh said. The first device, the SR-50, was introduced in September 2000 and supports 10/100 connections. The SR-55 adds Gigabit Ethernet with two 10/100/1000 ports. It also has a switch-to-wire fault tolerance features allowing traffic to continue to flow in the event of a failure, officials said. Pricing for both devices starts at $6,000 for a 256K-bps WAN connection and ranges to $50,000 for a T-3 connection. The SR-55 price is $2,000 more than the SR-50.
