Activision has recently begun releasing a series of technical white papers that analyze the core networking and matchmaking mechanics used in modern Call of Duty titles, which are applicable to MW3 (2023):

Ping and Connection White Paper: This official Call of Duty white paper focuses on the "Ping is King" philosophy. It explains how the matchmaking engine prioritizes network stability and latency, which is the foundational technology for any multiplayer interaction, including local and LAN-based private matches.

Offline/Local Mode (Console): On modern consoles, MW3 (2023) supports a "Local Mode" accessible without an internet connection. This allows for private matches, though functionality is limited to specific maps and weapons available at launch.

Client-Server Model: Modern iterations use a client-server architecture where the server remains authoritative, even in a local setting, to prevent state desync between connected clients. Community-Driven Technical Guides
