SAN JOSE, California, March 14, 2006 -- Companies Use Emerging IETF TWAMP Standard That Provides IP Performance Metrics Across Any Network Element Including Set-Top Boxes, Edge and Core Routers, Switches, and Gateways

Brix Networks (, the trusted provider of the most widely deployed converged service assurance solutions, and Allied Telesyn (, a global provider of secure Ethernet/IP access solutions, today announced performance measurement interoperability using the Two-way Active Measurement Protocol (TWAMP), a draft standard by the Internet Engineering Task Force (IETF) IP Performance Metrics (IPPM) working group.

This announcement was made in conjunction with the opening day of the Spring 2006 Voice On The Net (VON) Conference & Expo being held here at the San Jose Convention Center, March 14-17, where Brix is exhibiting in booth 637.

As the first open standard protocol that enables the accessibility of IP performance metrics, TWAMP provides two-way, or round-trip, measurements between various network elements. Using TWAMP-enabled network infrastructures, network operators can initiate performance measurement transactions and collect round-trip performance metrics to provide extensive visibility into IP performance across their networks.

"Verizon's policy is to support open network environments and the development of open network standards and protocols, such as TWAMP, which would facilitate the exchange of traffic or control information between service providers and between different vendor platforms," said Dr. Roman Krzanowski, principal MTS, at Verizon. "TWAMP offers common, ubiquitous test functionality in multi-vendor data networks, and is simple enough to be implemented in hardware on small network elements, like home routers, along with large core routers or multifunction switches, but is also powerful enough to deliver accurate measurements."

"TWAMP is poised to open the heretofore proprietary measurement protocols and increase the availability of performance metrics across all networks regardless of vendors," asserted Kaynam Hedayat, vice president, engineering, and CTO, at Brix Networks and co-author of this protocol. "With TWAMP, the industry now has a clear choice when it comes to measuring IP service quality. You can either be locked-in with one vendor's proprietary approach, such as only relying on a router to measure a user's overall quality of experience, or use open, standards-based testing protocols that will function across different networks and with different vendors' products."

"Allied Telesyn is very pleased to be working with Brix Networks on the implementation of this new open standard," said Dr. Allan Miller, vice president of product management, for Allied Telesyn. "This is a key step towards the development of a standards-based approach to the measurement and reporting of service levels. In turn, this will allow service providers worldwide to enhance the provision of IP-based services to their customers."
