MOS based route selection using Netaxis Session Routing Engine

Session Routing Engine is us

Had a really good working lunch last week with special guest Laurent Debacker. Laurent runs fixed and mobile network operations for Belgian telco Voo and provided us with a very interesting talk about their implementation of the Netaxis Session Routing Engine.

Some of you might think there is nothing much to say about routing engines. After all, you just set one up, point traffic in the desired direction and your Uncle’s name is Bob. Maybe you employ least cost routing and periodically upload new rate cards. That’s about it when it comes to routing engines. Isn’t it?

Well maybe it is and maybe it isn’t. Classically routing engines are unwieldy beasts and offer little incentive for people to do anything imaginative with them. However the telco world is rapidly evolving and your routing implementation needs to evolve with it.

Here I offer you one scenario:

Least cost routing is important because if you don’t watch your supplier rate cards you can quickly rack up losses on any given routes. However if you don’t watch the quality of your chosen routes you can quickly lose customers, or at least build up sufficient levels of disatisfaction that they start to bombard your helpdesk.

If you had a means of actively monitoring the quality of lines to specific destinations you could avoid this. Happy customers mean higher spending customers.

Netaxis have a suit of products that are built around our Session Routing Engine. The combined system includes the Nemo Network Monitoring tool which provides MOS scores for specific calls and the Dory call simulator. When combined with the SRE you can produce data on the quality of specific connectivity partners and make routing changes in real time based on this quality. It is also possible to get network alerts telling you that specific destinations have had changes to the carrier. The new carrier may not be the lowest cost but could serve as an interim solution whilst you address the quality issue with the original.  

If you want to know more about how we can do this just get in touch.
