Re: [ledbat] Commitment to contribute by P2P-next project

Johan,

Sharing information explicitly among multiple connections from the
same client is a promising area.  (If I understood correctly the
direction of what you're doing.)

It'd be great to know more about the technique in question, and its
applicability to various forms of congestion control.  Is it a
specific congestion control mechanism or a way to modify other
congestion control mechanisms to take advantage of the knowledge that
the upload is 1:n?

Thanks,
