Abstract

One embodiment of the present method and apparatus for multi-protocol digital communications conducts a first portion of a communication between a first information processing device and a second information processing device in accordance with a first communication protocol. A second portion of the communication is conducted in accordance with at least a second communication protocol, where the second communication protocol is different from the first communication protocol. The communication may be divided into further portions, where each portion of the communication is conducted in accordance with a different communication protocol.

Claims

1. A method for communication between a first information processing device and a second information processing device in a network, said method comprising the steps of:

selecting two or more different communication protocols for use in two or more sequential subsets of a communication between said first information processing device and said second information processing device;

conducting a first portion of said communication in accordance with a first communication protocol from said selected two or more communication protocols; and

conducting a second portion of said communication in accordance with at least a second communication protocol from said selected two or more communication protocols.

2. The method of claim 1, wherein at least one of the first communication protocol and the second communication protocol is selected from a library of communication protocols.

3. The method of claim 1, wherein at least one of the first communication protocol and the second communication protocol is created dynamically.

4. The method of claim 1, wherein at least one of the first communication protocol and the second communication protocol is a modified version of a common communication protocol.

5. The method of claim 4, where said modifications are made by at least one of:

using a different value for at least one default value or varying an order in which two or more values are stored in a header.

6. The method of claim 1, wherein a point in said communication at which said first communication protocol is replaced with said second communication protocol is selected in accordance with a meta-protocol exchanged by the first information processing device and the second information processing device.

7. The method of claim 6, wherein said meta-protocol is variable over time.

8. The method of claim 6, wherein said meta-protocol further specific how to select said second protocol.

9. The method of claim 1, wherein a point in said communication at which said first communication protocol is replaced with said second communication protocol is selected in accordance with at least one calculation based on information shared by the first information processing device and the second information processing device.

10. The method of claim 9, wherein said information is at least one of:

a shared secret or binary data.

11. The method of claim 1, wherein a point in said communication at which said first communication protocol is replaced with said second communication protocol is selected in accordance with a sequence of unpredictably changing algorithms.

12. The method of claim 1, wherein a selection of a communication protocol comprising said second communication protocol is made in accordance with at least one observed characteristic of at least one previous communication over said network.

13. The method of claim 12, wherein said at least one observed characteristic is a performance of at least one communication protocol used in said at least one previous communication.

14. The method of claim 1, wherein at least one of said first communication protocol and said second communication protocol is selected prior to a start of said communication.

15. The method of claim 1, wherein selection of at least one of said first communication protocol and said second communication protocol is made so as to encode at least a portion of said communication.

16. The method of claim 15, wherein information required to decode said at least a portion of said communication is sent only after said at least a portion of said communication is sent.

17. The method of claim 1, wherein said communication is dynamically divided into said first portion and said second portion during a course of said communication.

18. A computer readable medium containing an executable program for communication between a first information processing device and a second information processing device in a network, said method comprising the steps of:

selecting two or more different communication protocols for use in two or more sequential subsets of a communication between said first information processing device and said second information processing device;

conducting a first portion of said communication in accordance with a first communication protocol from said selected two or more communication protocols; and

conducting a second portion of said communication in accordance with at least a second communication protocol from said selected two or more communication protocols.

19. The computer readable medium of claim 18, wherein at least one of said first communication protocol and said second communication protocol is selected prior to a start of said communication.

20. Apparatus for communication between a first information processing device and a second information processing device in a network, said method comprising the steps of:

means for selecting two or more different communication protocols for use in two or more sequential subsets of a communication between said first information processing device and said second information processing device;

means for conducting a first portion of said communication in accordance with a first communication protocol from said selected two or more communication protocols; and

means for conducting a second portion of said communication in accordance with at least a second communication protocol from said selected two or more communication protocols.
