Comtech EF Data announces new Durostream WAN optimization appliances

Comtech EF Data Corp., a subsidiary within Comtech Telecommunications Corp.´s (NASDAQ: CMTL) Commercial Solutions segment, has announced the introduction of new Durostream AHA725 and AHA723 WAN Optimization appliances with packet protection from its AHA Products Group, the company said.

The AHA725 model is packaged in a 1RU rack-mountable chassis and supports WAN data rates up to 1 Gbps. The AHA723 is the compact form factor model that supports WAN data rates up to 50 Mbps.

The Durostream WAN Optimization solution provides a resilient, full-duplex, point-to-point survivable tunnel that dynamically adapts to network conditions to maximize throughput and minimize latency. The products address the challenge of packet loss on unreliable networks when streaming video or transmitting time-sensitive data.

At just 1% packet loss on a 1 Gbps WAN link and 10ms round trip time, a normal unprotected link using TCP/IP will only achieve 2.8% of the theoretical throughput as opposed to 96.6% if the same link is protected with Durostream. Forward error correction technology and header compression are employed to ensure protocol overhead and latency due to retransmissions are minimized while retaining the ability to overcome sustained packet loss rates of 75%.

Durostream is particularly suited to protecting VoIP traffic, streaming video, live event broadcasts, public safety and critical infrastructure communications, business continuity and disaster recovery operations, remote backups, and general data transfer. By placing a Durostream appliance at both ends of a WAN link, data loss and decreased throughput due to suboptimal network infrastructure can be avoided.

Comtech Telecommunications Corp. designs, develops, produces, and markets innovative products, systems and services for advanced communications solutions. The company sells products to a diverse customer base in the global commercial and government communications markets.
