2. Differences in game networking Peer-to-peer Client/Server Distributed Server

3. Peer-to-Peer Direct player connection –Reduced latency Multiplayer connection –Lack of control

4. Client/Server Client is the server –Dual players –Multiplayer –Central control –Increased latency

5. Distributed Servers Central control Uniform game Distributed resource load

6. Distributed Server Control Clients cheat Checksums –Error checking –Encryption

7. Distributed Servers Types Multi Realm Multi Shard Single Realmed

8. Distributed Servers Types cont. Multi realm –Many servers running different aspects –Shard/Area cap

9. Distributed Servers Types cont. Multi sharded –Multiple instances, across multiple servers –Distribute server load

10. Distributed Servers Types cont. Single Realmed –Many servers, one game –Server tricks –Client tricks

11. Future of MMO networks Single Realm Dynamic Player interaction Increased Throughput
