Comtech EF Data Announces New Durostream WAN Optimization Appliances with Packet Protection

August 27, 2018 

Comtech EF Data Corp., announced today the introduction of new Durostream AHA725 and AHA723 WAN Optimization appliances with packet protection from its AHA Products Group. 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.

“Our Durostream product line enables the use of unreliable existing network infrastructure for broadcasters, enterprise and government users,” stated Joel Bifford, Sales Manager for AHA Products. “Having two model options allows even cost-sensitive users with lower bandwidth and limited space applications to leverage the operational benefits of Durostream on previously unusable networks.”
