[dccp] DCCP buffer space shared with TCP?

[Leo Osvald]

Hi folks,

Might be a dumb question, but I would appreciate if someone could answer:
1) If I use DCCP protocol on Linux for one connection and TCP for 
another and both connections send data concurrently, would they compete 
for any (shared) buffer space in the OS, or they are completely 
independent of each other?
2) If the buffers are independent, is there a good way to ensure 
fairness, such that it doesn't happen that DCCP connection never gets 
its turn because TCP connection is sending all the time?

Thanks,
Leo
