Abstract
The subject disclosure relates to a method and apparatus for routing data in a network-based computer game via proxy computers. The method and system includes a set of techniques that utilizes the proxy computers to thwart traffic analysis in high-speed games while continuing to satisfy the games' latency requirements. The method and apparatus facilitates thwarting multiple classes of traffic analysis, including inspection of unencrypted header fields, observation of packet size, correlation of packet timing, and collusion among players. A matchmaking system for matching players in a network-based computer game in a manner that resists traffic analysis is also provided.
