Abstract

A method of operating a communication system which comprises a plurality of clients and a data repository, comprises the steps of detecting a location change of the data repository, acquiring data defining the clients connected to the data repository, transmitting a component to each client defined by the data, receiving the component at each client, and updating a user link to the data repository, at each client, according to the component. The step of transmitting a component to each client defined by the data comprises can comprise replicating an agent for each client.

Claims

1. A method of operating a communication system, the system comprising a plurality of clients and a data repository, the method comprising the steps of

detecting a location change of the data repository,

acquiring data defining the clients connected to the data repository,

transmitting a component to each client defined by the data,

receiving the component at each client, and

updating a user link to the data repository, at each client, according to the component.

2. A method according to claim 1, and further comprising notifying each client of the updating of the user link.

3. A method according to claim 1 wherein the step of acquiring data defining the clients connected to the data repository comprises accessing an access control list.

4. A method according to claim 1 wherein the step of acquiring data defining the clients connected to the data repository comprises accessing a user log.

5. A method according to claim 1 wherein the step of transmitting a component to each client defined by the data comprises replicating an agent for each client.

6. A communication system comprising a plurality of clients, a data repository and an agent, the agent arranged to detect a location change of the data repository, to acquire data defining the clients connected to the data repository, and to transmit a component to each client defined by the data, and each client arranged to receive the component at each client, and to update a user link to the data repository, at each client, according to the component.

7. A system according to claim 6, wherein the agent is further arranged to notify each client of the updating of the user link.

8. A system according to claim 6 wherein the agent is arranged, when acquiring data defining the clients connected to the data repository, to access an access control list.

9. A system according to claim 6 wherein the agent is arranged, when acquiring data defining the clients connected to the data repository, to access a user log.

10. A system according to claim 6 wherein the agent is arranged, when transmitting a component to each client defined by the data, to replicate an agent for each client.

11. A computer program product on a computer readable medium for operating a communication system, the system comprising a plurality of clients and a data repository, the product comprising instructions for detecting a location change of the data repository, for acquiring data defining the clients connected to the data repository, for transmitting a component to each client defined by the data, for receiving the component at each client, and for updating a user link to the data repository, at each client, according to the component.

12. A computer program product according to claim 11, and further comprising instructions for notifying each client of the updating of the user link.

13. A computer program product according to claim 11 wherein the instructions for acquiring data defining the clients connected to the data repository comprises instructions for accessing an access control list.

14. A computer program product according to claim 11 wherein the instructions for acquiring data defining the clients connected to the data repository comprises instructions for accessing a user log.

15. A computer program product according to claim 11 wherein the instructions for transmitting a component to each client defined by the data comprises instructions for replicating an agent for each client.
