UDP Load Balancing for Radius traffic.

I do but will have to see if I can use it here (legal issues). But for now I will try to explain it better.

 

 

AAA Service Controllers, using Radius protocol via UDP, make a request to our prepaid system servers, servers with database of subs and which prepaid server has the information, and they in turn query the end systems to see if the sub is authorized on the prepaid system and what balance is left. The gateway servers in turn reply back to the AAA's with an okay or rejection. The servers behind the F5's are a form of "gateway" that takes the Radius protocol tarffic and converts it to Diameter protocol which is used in the communication with the back end prepaid units. The F5's are between the AAA's and the gateways. I need to add in additional gateways for capacity and the AAA's do not have the code to be able to talk with more than 1 gateway at a site. Hence the need to load balance to a pool of gateways behind the F5's and have the AAA's think they are just talking to 1 gateway.

 

 

Thanks for helping.
