Juniper to Acquire Peribit for WAN Optimization

Juniper Networks agreed to acquire Peribit Networks, a developer of WAN optimization technology, for approximately $337 million in cash, stock and assumed stock options.

Peribit WAN optimization architecture uses compression, sequence caching, latency reduction, bandwidth management, path optimization, and visibility tools to improve congested enterprise WAN links.

Peribit, which was founded in 2000, developed a Molecular Sequence Reduction (MSR) technology that applies DNA pattern matching algorithms recognize repetitive bits of data traversing a point-to-point WAN link.

The sequence caching technology records patterns across packets, sessions, and flows and store them on hard disk so that, if repeated later, they can be identified and removed from data streams even when they are separated by hundreds of gigabytes of data sent days or weeks apart, and even when the transmitted files have been modified. Peribit also developed a Packet Flow Acceleration (PFA) technology that addresses poor application performance caused WAN latency. WAN latency tends to delay the acknowledgements between send and receive endpoints and this impedes an application's ability to send additional data while it's in a "wait state." Peribit's PFA technology accelerates short flows by optimizing the TCP session initialization. For large bulk data transfers, PFA minimizes the TCP idle time during which the server is unable to transfer more data due to WAN latency. This results in an optimized data flow from sender to receiver and a significant reduction in the total time to completion for the data transfer.

Peribit's products have been installed in over 900 enterprises worldwide.

  • Earlier this month, Peribit Networks introduced an Application Flow Acceleration (AppFlow) that transparently speeds performance of Microsoft Exchange, file services, and web-based applications over point-to-point links. Peribit's AppFlow technology accelerates the performance of applications based on three specific protocols: the Messaging Application Programming Interface (MAPI) used by Exchange; Microsoft CIFS; and HTTP. The AppFlow technology improves response times for remote Outlook/Exchange users by requesting portions of the message in advance of the client's request, pipelining what had been a serial and inefficient bulk transfer. As a result, the entire e-mail and any attachments are local to the client by the time the client requests the message.

  • Peribit Networks was founded in May 2000 by Dr. Amit P. Singh, a researcher at Stanford University, and Balraj Singh, who previously was part of the original design team for Intel's Pentium.
