How to limit the total volumn from a TCP connection

I have a particular application with one type of connection that mostly sends packets to clients while receives nothing but login request. (i.e. video streaming)

Therefore I want to limit the Total Volumn Received from a TCP connection (websocket connection to be specific) within a maximum amount. Anything beyond that would result in connection drop.

At the application level, there is still not a limit on how large the websocket message received can be. So it is prone to sheer volumn attack until a security measure is enforced.

Thanks for any advice. -- Add: CentOS Linux with Nginx or HAproxy as reverse proxy--
