How to raise the priority of Internet traffic for one application / program?

Question

Network administration

Hello. I would like to know how to direct all Internet traffic to one application? Let's say it's a torrent client. I want only this application to "suck" all the speed and be in the first place in the use of the Internet connection. Maybe there are some programs that cut the connection to all programs and processes, except for this one? Thanks in advance for your reply.
