Mark Rubin, Call of Duty executive producer, has revealed during an update on Twitter that all game console platforms, current and next-generation will take advantage of dedicated servers for Call of Duty: Ghosts in order to producer the best possible online experience.
GHOSTS ONLINE CONNECTIVITY UPDATE: I wanted to give a quick update on some of the work that has been done to improve everyone’s online experience. We’ve already mentioned dedicated servers as part of the overall plan to improve connectivity. Dedicated servers will be used on current gen, next gen and PC with Ghosts. And, in order to make sure that people have the best possible experience regardless of platform, location or connection, Ghosts will be using a hybrid system of dedicated servers and listen servers. So no matter where you are the game will always be trying to give you the best online performance possible. There is also some great new tech in the matchmaking system that will place players in matches that have the best combined overall connectivity performance. Again these are just some of the things that are going into Call of Duty: Ghosts to give players a great online experience. Can’t wait to see you all online.”
A dedicated server is one that is remotely or locally run through a game client to play multiplayer video games. These servers are known for their suitability, reliability, and performance benefits that comes with hosting in a professional data center. Remote hosting effectively eliminates the low-latency (or lag) advantage that would otherwise occur when a player self-hosts through their local network.
Dedicated servers are without cost though. As if you’re looking to host you’re own server, you’ll have to pay a sum. Often times, however, the cost will be covered by the third party (usually on consoles).
Dedicated servers are worthless for games which only support low player counts.
