Abstract

The disclosure relates to a multi-user application that is configured to operate in various network communication configurations and that can dynamically change communication configurations during an online session of the application. One of the network communication configurations is a client-server configuration, wherein network computers, including at least one server computer and at least one client computer, participate in an online session of the application. The server computer serves application-related data to the client computer during the online session. In another communication configuration of the application, the network computers operate in a peer-to-peer configuration wherein the network computers have the ability to both serve data to and receive data from any of the other network computers that are participating in the online session. The application can switch between the communication configurations during an online session, and is not limited to one or the other for all the computers.

Claims

1. A method of dynamically configuring an online session of a multi-user application that operates on a computer network, comprising:

establishing communication connections between at least two computers on the computer network, each of which is executing the multi-user application, to thereby establish an online session of the multi-user application, wherein the multi-user application defines communication configuration types that are applied during the online session;

designating one of the computers as a session master computer that is responsible for managing functionality associated with the multi-user application;

detecting that the session master computer has exited the online session;

designating a second computer as the session master computer so that the second computer is responsible for managing the functionality associated with the multi-user application; and

determining if a current communication configuration type should be changed on-the-fly based on a state of the established communication connections for the online session, as defined by the multi-user application for the online session after the designation of the second computer as the session master and wherein changing of the communication configuration type is to change the communication protocol by selecting a new port or network socket through which an instance of the application communicates over the network.

2. A method as define in claim 1, wherein the first computer and the second computer are initially arranged in a client-server communication configuration, and wherein the first computer is a server computer and the second computer is a client computer relative to the first computer.

3. A method as define in claim 1, wherein the application also designates a third computer as a session master computer that shares responsibility for managing the functionality associated with the multi-user application with the second computer so that the second and third computers are in a peer-to-peer communication configuration.

4. A system that dynamically configures an online session of a multi-user application, the system comprising one or more processors that execute program instructions and receive a data set, wherein the program instructions cause the system to perform operations including:

establishing communication connections between at least two computers on the computer network, each of which is executing the multi-user application, to thereby establish an online session of the multi-user application, wherein the multi-user application defines communication configuration types that are applied during the online session;

designating one of the computers as a session master computer that is responsible for managing functionality associated with the multi-user application;

detecting that the session master computer has exited the online session;

designating a second computer as the session master computer so that the second computer is responsible for managing the functionality associated with the multi-user application; and

determining if a current communication configuration type should be changed on-the-fly based on a state of the established communication connections for the online session, as defined by the multi-user application for the online session after the designation of the second computer as the session master and wherein changing of the communication configuration type is to change the communication protocol by selecting a new port or network socket through which an instance of the application communicates over the network.

5. A program product for use in a computer system that executes program steps recorded in a computer-readable media to perform a method of dynamically configuring an online session of a multi-user application, the program product, wherein the program steps comprise:

establishing communication connections between at least two computers on the computer network, each of which is executing the multi-user application, to thereby establish an online session of the multi-user application, wherein the multi-user application defines communication configuration types that are applied during the online session;

designating one of the computers as a session master computer that is responsible for managing functionality associated with the multi-user application;

detecting that the session master computer has exited the online session;

designating a second computer as the session master computer so that the second computer is responsible for managing the functionality associated with the multi-user application; and

determining if a current communication configuration type should be changed on-the-fly based on a state of the established communication connections for the online session, as defined by the multi-user application for the online session after the designation of the second computer as the session master and wherein changing of the communication configuration type is to change the communication protocol by selecting a new port or network socket through which an instance of the application communicates over the network.
