Abstract

In the event of an unintentional interruption, a token issued by a host system to a client system is used to reestablish communications without disrupting applications on the client system. If the host system provided an Internet Protocol address to the client system to be used during the interrupted communications session, the host system reserves the communications address during an interruption in communications for a period sufficient to permit reestablishment of communications using the reserved address.

Claims

1. A method for communicating between a client and an accessible system, the method comprising the following operations performed by one or more processors:

sending to the client, from the accessible system, an accessible-system-designated communications address for accessing the accessible system;

sending to the client, from the accessible system, a reconnection token;

detecting an interruption in a communications session involving the client;

reserving the accessible-system-designated communications address during the period of the interruption;

receiving the reconnection token from the client;

authenticating the reconnection token; and

reestablishing the communications session.

2. The method of claim 1, further comprising receiving, at the accessible system, a request from the client for a communications session between the client and the accessible system.

3. The method of claim 1, further comprising receiving, at the accessible system, a request from the client for the reconnection token.

4. The method of claim 1, wherein the reconnection token has a lifespan that is determined by the accessible system.

5. The method of claim 1, wherein authenticating the reconnection token comprises comparing the reconnection token with a list of valid tokens.

6. The method of claim 1, wherein the accessible-system-designated communications address is unique to the client.

7. The method of claim 1, wherein reestablishing the communications session occurs without the client detecting the interruption.

8. The method of claim 1, wherein receiving the reconnection token from the client comprises receiving the reconnection token and authentication information from the client.

9. The method of claim 1, further comprising masking the interruption from the perspective of the client.

10. The method of claim 1, wherein receiving the reconnection token from the client occurs after detecting the interruption.

11. A computer-based system comprising one or more processors and one or more storage media storing a plurality of instructions, the plurality of instructions being executable by the one or more processors for

participating in an electronic communications session;

receiving, from an accessible system, an accessible-system-designated communications address for accessing the accessible system;

receiving, from the accessible system, a reconnection token;

sending, after the occurrence of an interruption in the electronic communications session, the reconnection token to the accessible system using the accessible-system designated communications address; and

continuing to participate in the electronic communications session after the electronic communications session has been reestablished by the accessible system.

12. The computer-based system of claim 11, further comprising instructions being executable by the one or more processors for sending, to the accessible system, a request for the electronic communications session.

13. The computer-based system of claim 11, further comprising instructions being executable by the one or more processors for sending, to the accessible system, a request for the reconnection token.

14. The computer-based system of claim 11, wherein the reconnection token has a lifespan that is determined by the accessible system.

15. The computer-based system of claim 11, further comprising instructions being executable by the one or more processors for:

determining whether the reconnection token is stored in the one or more storage media; and

accessing the reconnection token from the one or more storage media.

16. The computer-based system of claim 11, wherein the accessible-system-designated communication address is unique to a client participating in the electronic communications session.

17. The computer-based system of claim 11, wherein the electronic communications session is reestablished without a client participating in the electronic communications session detecting the interruption.

18. The computer-based system of claim 11, wherein sending the reconnection token comprises sending the reconnection token and authentication information.

19. The computer-based system of claim 11, wherein the interruption is masked from the perspective of a client participating in the electronic communications session.

20. The computer-based system of claim 11, wherein receiving the reconnection token occurs before the occurrence of the interruption in the electronic communications session.
