The forces behind increasing Diameter signaling

I want to discuss some of the issues pushing the amount of signaling and Diameter.
We see growing amount of Diameter traffic in the networks, presenting Service providers with new challenges of managing Diameter traffic, scalability and confronting bottlenecks in their networks.

Here are some of the reasons for the growing amount of Diameter signaling
- Subscriber growth and subscribers migration to Next Gen. Networks
- Flat rate plans for data services
- Growing amount of Converged networks
- Diameter maturity with growing amount of interfaces and connectivity
- Continuing network migration to NGN
- Growing number of enforcement (DPI/PCEF) and policy (PDF/PCRF) functions, which are major source of Diameter signaling
- Increase in new services
- Continuing migration from 2G/2.5G to 3G, NGN and beyond (e.g. LTE)
- New interface speeds

Another important affect to take into consideration is that with the increase in network and signaling complexity and traffic of Diameter signaling in NGN, the network management becomes a growing concern, with new issues (surprisingly familiar from the days of SS7 based networks) related to identifying, analyzing and solving network related issues.
All those signaling and Diameter related issues can result in growing maintenance and management costs, increasing downtime, QoS issues, customer satisfaction and of course Service providers revenues.

To confront those issues, Services providers need to add and scale NGN infrastructure capacity, and to take into account Diameter and network design, scalability, signaling balancing and routing when charting new NGN related RFP’s.
Here at Traffix we offer them a set of products to confront those issues, from Diameter Gateways to confront vendor and standard interoperability issues, through Diameter load balancers and up to advanced contextual signaling and Diameter management solutions.
