Abstract: A method and system that enhances a user's performance while interacting with an interactive internet application such as a Massively Multiplayer Online (MMO) game is provided. The network latency experienced by users participating in the MMO game is minimized by dynamically determining an optimal transmission action for a message generated by the MMO game. In one embodiment, determining the optimal transmission action for a message includes dynamically determining the optimal number of redundant Forward Error Correction (FEC) packets to add to a message prior to transmitting a message to a receiving device. The optimal number of FEC packets is determined based on a wide range of varying network conditions.

Abstract: A system and method for signing data transferred over a computer network is described. In one aspect, the HTTP header of an HTTP response message is extended to include a content identifier, a content expiration time, and a digital signature. The digital signature may be generated from the content identifier, the content expiration time, and the message body of the HTTP response message.

Abstract: Dynamic role selection of players for different roles in multiplayer gaming sessions is provided. Users seeking to participate in different roles in the game may request participation in the role. Selection of players for roles is made dynamically by varying a selection component for different sessions of the game. The selection component may be a user's game score over different time periods, and can be rotated for different sessions of the game, so that various levels of players have an opportunity to fill game roles.

Abstract: A massively multiplayer game management service includes a scheduling module that establishes a message receiving period and a game data aggregation period. The massively multiplayer game management service further includes a message receiving module that, during the message receiving period that overlaps at least part of the game data aggregation period, receives a message from a player client. The message may include an identifier and an execution time that follows the game data aggregation period. The massively multiplayer game management service further includes a message sending module that sends game data, aggregated in a game space location corresponding to the identifier, to the player clients upon occurrence of the execution time.

Abstract: Disclosed herein is a set of coordinated game service primitives that allows for custom, per-game, logic. A new game with new custom logic can be added without needing to change any public api or database schema or write any new server code. The same hardware may be shared across many games. And the system scales linearly. That is, if the number of servers is doubled, then so is the number of concurrent users that can be supported. Also disclosed are systems and methods for two-stage aggregation. Pre-aggregation may take place on a plurality of front-end server. Final aggregation may take place on one or more back-end servers. A name value store may be used to reliably store state.
