Reducing memory usage for 2^16 streams

[lgrahl]

Considering that a decision against using RE-CONFIG has been made for the WebRTC Data Channel specification, are there any plans to reduce memory usage when requesting to use 2^16 streams?

Yes, there is a plan for using a late allocation strategy.

Ping! Do you have an estimate when this is going to be resolved? You can also give me hints where I need to look at and I'll try to address this myself.

This is not high priority... It is an optimisation. You would need to look at places where the structures for the incoming and outgoing streams are allocated and add one layer of indirection. The critical part is the place where a delayed memory allocations fails (this can happen in kernel land), then you have to fail the association, I guess.
