Re: [tipc-discussion] [net-next 0/3] tipc: introdice variable window congestion control

[Jon M. <jon...@er...>]

Just so there is no misunderstanding: this is a completely new version of the variable congestion window algorithm, comprising both slow start, congestion avoidance and fast recovery.
I maybe should have added a v5 is similar to it...
Performance is consistently better than in the previous versions.
