July 21, 2011 -- Traffix Systems, the Diameter control plane experts, today announced its Distributed Signaling Grid (G-SDC) consisting of an intelligent contextual routing layer that unifies multiple Traffix Signaling Delivery Controller (SDC) nodes into a single, network-wide distributed system with centralized management. Based on field-deployed proven technology, the Traffix G-SDC offers a holistic approach for all network-wide signaling, particularly beneficial for large carrier networks with multiple network data centers.

Designed for large scale carrier networks supporting multi-site, policy deployment requirements, the Traffix G-SDC provides carriers with a powerful signaling "cloud" enabling each element to interconnect to any point, efficiently routing its signaling traffic without concern for network resource availability. This cloud-like configuration for signaling exceeds large carrier's requirements for LTE network performance.

"As LTE is deployed and data use surges, signaling traffic grows exponentially and operators will need new tools to handle large signaling surges. The Traffix G-SDC can simplify and harmonize networks to maintain reliability and scalability," commented Sue Rudd, Director Service Provider Analysis at Strategy Analytics. "This is a welcome solution for large scale deployments that should lower operational and capital expenses and provide interoperability with legacy 2.5 and 3G networks."

The Traffix Distributed Signaling Grid is constantly aware of interconnecting node availability, and is able to shift signaling flows to servers based on their availability and capacity. Simultaneously, it maintains network-wide, distributed state information enabling all the signaling routing components to work in harmony. Its built-in throttling capabilities actively monitor and manage traffic from each node, limiting throughput to servers based on their rated capacity. In situations of overload, the G-SDC can detect which packets should be dropped to prevent servers from overwhelming the network, leading to outages.

When carriers deploy the Traffix Distributed Signaling Grid, the message origin or subscriber location is irrelevant - it will always be routed to the correct server or service," said Lenny Ridel, CTO at Traffix Systems. "This advanced dynamic routing technology guarantees throughput, minimize latency and downtime. As a result, the LTE network performs consistently and predictable, coordinated to perfection despite the huge scale of many data centers and the distributed nature of the signaling flows."
