In an interview with Splash Damage Software's creative director Richard Ham, he explains many features of the online multiplayer aspect of Brink, a futuristic FPS with a revolutionary free-flow system called S.M.A.R.T.
Ham outlines the use of VAC and dedicated servers for the PC version, as well as a developer console for changing game CVARS. Ham explains "As we're a Steam game, we will be using VAC. On top of that, we're big proponents of giving players the tools to police themselves and weed out the bad apples."
Ham also gives a bit of information on the online aspect of the console versions aswell:
"For consoles, we're peer-to-peer and are definitely focusing on quality of service for all our matchmaking. We're also keying our matchmaking on friends, so that should help give console players control over the quality of the connections."
