Abstract

A messaging system may enable a server to assign unique identifiers to a plurality of clients. These identifiers enable a client to determine whether a message is specifically targeted to that client or, as an alternative, whether the client is a member of a group of targeted clients. A server may send messages containing an identifier to agents on one or more clients. The identifier may specify commands to control the storage of information on one or more clients.

Claims

1. A method comprising:

receiving on a first client a message from a server addressed to said client;

controlling management of data storage by said client based on information included in said message;

defining a messaging service type and message identification to dynamically control storage for groups of clients or individual clients;

assigning an individual identifier to the clients comprising a set of clients including said first client;

assigning a group identifier to a subset of the clients within the set of clients; and

enabling the first client in said set to determine whether a message is sent to the first client or to the subset.

2. The method of claim 1 further including sending a single message to a subset of said clients.

3. The method of claim 1 including sending television content to a plurality of clients.

4. The method of claim 1 wherein assigning an individual identifier includes assigning a code portion that identifies a particular client as belonging to a subset of clients within the set of clients.

5. The method of claim 4 including comparing a group identifier, received by a client with a message, to the client'"'"'s individual identifier to determine whether the particular client is within the addressed subset.

6. The method of claim 1 including addressing the same message to a subset of clients.

7. The method of claim 1 including sending a message to a client in a unidirectional messaging system.

8. The method of claim 1 including receiving a message including an identifier which specifies a task to perform on a storage device.

9. The method of claim 8 including receiving a message including an identifier indicating a change to a partition on said storage device.

10. The method of claim 1 wherein controlling management of data storage includes controlling the organization of how data is stored by said client.

11. An article comprising a medium storing instructions that enable a processor-based system to:

receive on a first client a message from a server addressed to said client;

control management of data storage by said client based on information included in said message;

define a messaging service type and message identification to dynamically control storage for groups of clients or individual clients;

assign an individual identifier to a client comprising a set of clients;

assign a group identifier to a subset of the client within the set of clients; and

enable a first client in said set to determine whether a message is sent to the first client or to the subset.

12. The article of claim 11 further storing instructions that enable the processor-based system to send a single message to a subset of said clients.

13. The article of claim 11 further storing instructions that enable the processor-based system to send television content to a plurality of clients.

14. The article of claim 11 further storing instructions that enable the processor-based system to assign a code portion that identifies a particular client as belonging to a subset of clients within the set of clients.

15. The article of claim 14 further storing instructions that enable the processor-based system to compare a group identifier, received by a client with a message, to the client'"'"'s individual identifier to determine whether the client is within the address subset.

16. The article of claim 11 further storing instructions that enable the processor-based system to address the same message to a subset of clients.

17. The article of claim 11 further storing instructions that enable the processor-based system to send a message to a client in a unidirectional messaging system.

18. The article of claim 11 further storing instructions that enable the processor-based system to decode a command within said message to modify the storage of information on a storage device.

19. The article of claim 18 further storing instructions that enable the processor-based system to modify a partition on said storage device in response to a command included within said message.
