dispatcher(k): basic framework for load dispatching
- a lightweight system to do a fair distrubution based on load - no dependency on dialog, by using an internal table of active calls with minimal info, to keep the module suitable for small devices and have good performances - not completed, requires xavp support for a compact info structure to be carried in transaction for each failover step

This sounds really cool.

Hi, where and how is such info about "active calls" stored? If it doesn't depend on "dialog" module how are active calls deleted when there is no BYE signalling and so?
Regards.

it is an internal hash table with minimal info.

this is load balancer, probably you will have the proxy or application server behind that will detect it. I don't think you need to balance calls to users. However, there is a max timeout for dispatcher active calls, just in case ... so the resource is automatically released when time expires.
Cheers, Daniel

Ok, understood, thanks :)
