How can I change different TCP parameters in Openstack. For example How I can increase or decrease TCP window size? I'm also interested to know how I can increase the bandwidth in my management network for live migration. I'm using a 1 Gigabit infrastructure for my management network. However, live migration just use 120Mb out of that 1 gigabit while the rest of the bandwidth is used for very low volume of traffic.

Management network is using your infrastructure MTU. On your switches enable Jumbo Frames and change MTU on your servers on mgmt interfaces. Also, you need to configure QoS on your switches to be able to manage your traffic in network.

MTU is a general parameters. I want to focus on protocol parameters not general parameters. QoS also is more of network parameters not a specific protocol parameters
