Abstract

A method and device are provided for conducting a real-time, voice over IP media type of communication session between at least two peer users, each associated with a platform comprised in a distributed communication network. The method and device comprise providing at least one replication of at least one data object to all other platforms associated with that distributed communication network.

Claims

1. A method for conducting a real-time, voice over IP media type of communication session between at least two peer users, each associated with a platform comprised in a distributed communication network, wherein the method comprises providing at least one replication of at least one data object to all other platforms associated with said distributed communication network.

2. A method according to claim 1, further comprising a step of providing of a notification at all platforms associated with said distributed communication network, indicating the creation or modification of said at least one data object.

3. A method according to claim 1, wherein at least two of said at least two peer users are associated with a single platform.

4. A method according to claim 3, and wherein no replication is created at the platform associated with said at least two of said at least two peer users.

5. A method according to claim 1, wherein at least two of said at least two peer users are each associated with different platform.

6. A method according to claim 1, wherein said real-time, voice over IP media communication session us established according to the steps of:

registering each of said at least two peer users at the distributed communication network;

at a platform associated with a first of said at least two peer users, creating a data object which comprises a request initiated by said first of said at least two peer users to establish a communication session with at least one other of said at least two peer users, and the identification of said at least two peer users;

providing a replication of said data object to all other platforms associated with said distributed communication network;

if said at least one other of said at least two peer users is associated with a platform other than the one with which said first of said at least two peer users is associated, receiving a notification at all platforms associated with said distributed communication network, indicating the creation or modification of said data object;

receiving a replication of said data object and processing it by a computational entity located thereat;

determining whether said real-time communication session may be established between said at least two peer users; and

if in the affirmative, establishing said real-time communication session between said at least two peer users.

7. A method according to claim 6, further comprising confirming the accessibility of the object(s) resident on one or more of said platforms associated with said at least one other of said at least two peer users, prior to the step of receiving a replication of said data object.

8. A method according to claim 6, wherein the step of receiving a replication of said data object, further comprises confirming the accessibility of object(s) resident on one or more of said platforms associated with said at least one other of said at least two peer users.

9. A method according to claim 8, wherein in case said object(s) is determined to be non-accessible, the step of receiving a replication of said data object further comprises repeating the step of confirming said object accessibility every pre-determined period of time.

10. A method according to claim 8, wherein in case said object(s) is determined to be non-accessible, the step of receiving a replication of said data object further comprises providing said object with a message indicating that a request to establish a communication session therewith is or was made.

11. A method according to claim 10, wherein said message indicating that a request to establish a call comprises an indication of the identity of the entity initiating said request to establish the communication session.

12. A method according claim 1, wherein said data object is transmitted in an encrypted form and is adapted to be decrypted by at least one entity with which said communication session is to be established.

13. A method according to claim 1, wherein all messages exchanged prior to establishing said communication session, are exchanged in an encrypted form that can be decrypted by entities to which said messages are directed.

14. A computer-readable medium containing instructions that perform a method, when executed by a processor, for conducting a real-time, voice over IP media type of communication session between at least two peer users, each associated with a platform comprised in a distributed communication network, wherein the method comprises sending at least one replication of at least one data object to all other platforms associated with said distributed communication network.

15. A computer-readable medium according to claim 14, further said method further comprises a step of sending a notification to all platforms associated with said distributed communication network, indicating the creation or modification of said at least one data object.

16. A computer-readable medium containing instructions that perform a method, when executed by a processor, for establishing a real-time, voice over IP media type of communication session in a distributed system, wherein the method enables computational entities to maintain references indicating the location of objects within the distributed system, by:

registering a first peer user at the distributed communication network;

at a platform associated with said first peer user, creating a data object which comprises a request to establish a communication session with at least one other peer user, and the identification of said first peer user and said at least one other peer user;

sending a notification to at least one platform associated with said at least one other peer user, indicating the creation or modification of said data object;

sending a replication of said data object to said at least one platform associated with said at least one other peer user;

determining whether said real-time communication session may be established between said first and said at least one other peer users; and

if in the affirmative, establishing said real-time communication session therebetween.

17. A distributed communication system comprising:

a first client system including an object; and

a second client system including;

a client process; and

a remote process configured, when executed by a processor, to register a request to establish a real-time, voice over IP media type of communication session with an object of the first client system, by;

providing a replication of the request to said first client system;

exchanging messages between the first and second client systems, and

based on the information retrieved from the messages exchanged, determining whether a communication session may be established between the first and second client systems;

if in the affirmative, establishing a communication session between the first and second client systems.
