MERA Systems announced the availability of its new fully distributed session controller architecture designed for large telcos such as Tier 1, major national and international carriers.
The MERA MVTS session controller consists of several interconnected signaling and media servers. The signaling servers share a single routing table and can therefore efficiently manage VoIP traffic throughout the entire network, irrespective of their physical location.
MERA said the clustered architecture of its session controller allows a capacity increase up to 40, 000 concurrent calls. The solution scales by adding extra servers. Along with regular backup redundancy, MERA's distributed session controller is "redundant in itself". Every signaling server is backed up by all the other signaling severs, and the same goes for media servers. In addition, MERA's signaling servers perform real-time bandwidth mapping and allocation, and send media flows across channels with better bandwidth, thus providing for greater service availability and customer-centric QoS policies.
Infotel Communication S.p.A., an Italy-based VoIP carrier, has deployed the MERA MVTS session controller with distributed architecture in its nationwide VoIP network for delivery of real-time voice services in Italy and abroad. MERA's cluster at Infotel Communication is composed of the MVTS signaling server and two media servers deployed in Milan, and handles VoIP traffic from 12 POPs in Italy and Europe, over 20 Tier 1 and Tier 2 international carriers, and a network of resellers and phone shops. All signaling flows are concentrated by the MVTS signaling server, which distributes calls between the media servers. With this architecture, media information does not have to follow the signaling flows, thus offloading the signaling server for higher traffic throughput.
