CAMPBELL, Calif. -- Exalt Communications, Inc., the leading innovator of next-generation packet microwave backhaul systems, today announced Adaptive Latency Control, a breakthrough approach to slashing latency and minimizing network noise in financial trading networks supporting high frequency trading (HFT). This patent-pending Exalt architecture enables microwave network planners to optimize financial trading networks for ultra-low latency by defining Exalt radio configurations on-the-fly with superior ease of deployment, on-board diagnostics, and economics. "In the early stages of the market, network operators tested traditional microwave as an alternative to fiber for financial trading, and they proved its superiority for high speed transmission," said Amir Zoufonoun, CEO of Exalt. "Now they are looking for a better microwave designed specifically to achieve ultra-low latency. This is next generation HFT microwave, and Exalt is delivering it today with advances in technology such as our unique Adaptive Latency Control." (For more specific information on Exalt and HFT, refer to related press release at www.exaltcom.com/HFT-Evolution.aspx.) While radios from traditional microwave vendors must be pre-configured as radios or repeaters, Exalt radios can be configured on-the-fly as network signal regenerators, network recoding systems, or endpoints. Regenerators pass on the microwave signal with the lowest possible latency, while recoding systems apply forward error correction (FEC) to the signal to eliminate noise that is introduced when the signal is simply regenerated. Endpoints down-convert the microwave signal and apply FEC for the Ethernet connection to the HFT network at each end of the microwave link. All of these modes are remotely selectable under software control, so network engineers can deploy the same Exalt system on each link and then, from a network operations center, optimize radio personalities to deliver the lowest latency with lowest noise over the end-to-end network.
