Is it possible to setup port priority in linux network stacks

georgewhr · 02-24-2014, 07:27 PM

Here is the scenario, once the transport layer receive packets from IP layer, it will forward packets to upper layer through sockets and port number. Is it possible to make a priroity queue which will store the packets and then forward those packets to application layer by a pre-set order?

For example, I have Http(80), SMTP(25), ssh(22) on transport layer, and what I want to do is put them in a queue and set http(80) higest priority to forward to higher level stacks, and then ssh, then smtp.

Hi, Thanks for the reply. I just checked struct sk_buff and there is a data in sk_buff called priority, sk_buff->priority. Do you know which layer this priority refers to? Or how this priority data variable works in linux network stacks?
