Make Network Fault Tolerance Your Advantage

Secure, multi-site redundancy using clustering technology can be a competitive advantage for network operators, while preparing them for NFV

LONDON – February 26, 2014 –  Metaswitch Networks is prompting service providers to reduce the costs of achieving reliable, multi-site redundancy through the use of its innovative clustering technology. Metaswitch’s Multiservice Telephony Application Server (MTAS) clustering enables network operators to build load-balanced, geographic redundancy across all their sites and make a step toward the virtualized network of the future.

Geographic expansion creates a constant pressure on network operators to spend more on hardware and associated operating costs to meet customer demands. With Metaswitch’s MTAS clustering, network operators have a flexible solution that allows them to increase their coverage using fewer sites and achieve higher scale for less investment than traditional offerings. Also, thanks to Metaswitch’s support for virtualized platforms, network operators also have the opportunity to reduce the amount of essential physical hardware now or in the future.

Metaswitch MTAS clusters provide:

Geographic Redundancy. Local high-availability and remote load-balanced geographic redundancy ensures full protection against equipment and site failure. With geoclustering  protection across multiple sites, Metaswitch also reduces opex by requiring less equipment in total to protect against site failure. Without the need for traditional explicit 1:1 site failover, MTAS clustering lets you design for “failover to any” and capitalize on total available capacity across all the sites.

Scalability. Each Metaswitch MTAS cluster is capable of handling 20 million busy-hour call attempts (BHCA), 10 million residential subscribers and 4 million business subscribers. This kind of performance allows network operators to manage increasing voice traffic without increasing their management overhead.

Flexibility. Network operators can add and remove nodes to clusters as demand grows. They can choose to make nodes virtual or physical, a solid step toward network functions virtualization (NFV). Metaswitch supports service providers in selecting their own hardware, or they can take advantage of field-proven ATCA hardware from Metaswitch.

Reliability. MTAS clusters have built-in load balancing to protect network operators in case of a site failure. When a site goes down due to power outage or a loss of network connectivity, the network self-diagnoses and traffic is automatically rerouted and rebalanced.

Superior Management and Diagnostics. Easily managed deployment through a single point of interface and shared configuration across the cluster. Metaswitch’s MetaView provides a one-stop point of management and industry-leading deep-inspection diagnostics with Service Assurance Server.

“Network operators are looking to provide better and increasingly reliable services for a market that grows more competitive and more demanding with each passing day,” says Paul Brittain, VP of VoIP and multimedia product at Metaswitch Networks. “With MTAS clustering, we are giving network operators unrivaled levels of protection against equipment failure and disaster events, simple sideways scaling, and an elegant route to NFV.”
