With its new ClariLink family of WAN link controllers, Ecessa gives small and midsized enterprises the load balancing and failover capabilities for network traffic previously unavailable to small and midsized enterprises. The ClariLink devices let IT administrators deploy SIP traffic across multiple WAN or service provider networks, offering redundancy and automatic failover in the event that a VOIP session is interrupted for any reason. If a VOIP session is ended because of a network problem, the call is automatically sent to another link, with little to no interruption.
Ecessa is rolling out a new family of WAN link controllers aimed at improving the performance and scalability of VOIP communications.
The ClariLink WAN link controller, announced May 12, balances SIP
(Session Initiation Protocol) traffic across multiple WAN links and
service provider networks, ensuring greater reliability, said John
Addington, director of technical services at Ecessa.
"One of the limitations we found with SIP traffic ... was particularly in regard to failover," Addington said.
Currently, during a VOIP (voice over IP) session, if there is an
interruption in the call, the person who is knocked off has to redial
in order to get back into the call.
"It's not a seamless VOIP experience," Addington said.
ClariLink is designed to act as a front-end controller, managing
disparate WAN links and capacity to offer redundancy in the link
connections and automatic failover.
With ClariLink, if there is an interruption in the VOIP
communications, the call is automatically moved to a second WAN link,
with possibly an interruption of a second or so, Addington said.
The new WAN link controller is aimed at small and midsized
enterprises. For these businesses, ClariLink gives them a more
effective way to mange their voice networks, and greater confidence in
integrating their voice systems with their data, multimedia and
With ClariLink, service providers, system integrators and VARs can
offer voice and data network optimization that previously had not been
available to SMEs, Ecessa officials said.
The product distributes network traffic among multiple network
links-such as cable, xDSL, T1 and satellite links-and offers
aggregation, automated inbound and outbound load balancing and failover
The ClariLink family of WAN link controllers will be available in the third quarter.
