Abstract

A communication network (1) having a number of server units (12, 14, 16) connected with each other on the data side, to each of which a number of terminals (20) is connected in a local environment, each server unit (12, 14, 16) including a data storage area (22, 24, 26) for saving message data, shall enable user access to the user-specifically saved message data from each of the local environments in a reliable and quick manner, even in case of limited data transmission capacity between the individual server units, maintaining at the same time an appropriate flow synchronization between the partial networks. For this purpose, each data storage area (22, 24, 20) comprises, according to the invention, a first partial storage area (42, 44, 46) for saving user data and a second partial storage area (52, 54, 56) for saving control data. During operation, the user data are stored on all server units (12, 14, 16) in a synchronized manner.

Claims

1. A communication network having a number of server units connected with each other on the data side, to each of which a number of terminals is connected in a local environment, each server unit including, for saving message data, the message data comprising user data and control data, a data storage area comprising a first partial storage area for saving user data and a second partial storage area for saving control data.

2. The communication network according to claim 1, wherein in each server unit of which a synchronization module is allocated to each first partial storage area said synchronization module, after a saving of new or changed user data not occasioned by another synchronization module, forwards the data to the respective other server units for saving the forwarded data in each of the other server unit'"'"'s respective first partial storage area.

3. The communication network according to claim 1, wherein each server unit comprises a filter module, which splits the incoming data flows into user data on the one hand and control data on the other hand.

4. The communication network according to claim 1, wherein each terminal has access to the user and control data saved on the server unit connected with said terminal.

5. The communication network according to any of claim 1, wherein message files are provided as user data.

9. The communication network according to claim 2, wherein each server unit comprises a filter module operable to split the incoming data flows into user data on the one hand and control data on the other hand.

10. The communication network according to claim 2, wherein each terminal has access to the user and control data saved on the server unit connected with the terminal.

11. The communication network according to claim 3, wherein each terminal has access to the user and control data saved on the server unit connected with the terminal.

12. The communication network according to claim 2, wherein message files are provided as user data.

13. The communication network according to claim 3, wherein message files are provided as user data.

14. The communication network according to claim 4, wherein message files are provided as user data.

6. A method for storing message data in a communications network comprising:

providing a number of server units connected with one another on a data side and, to each of the server units is connected a number of terminals in a local environment; and

storing message data in a data storage area in each of the server units, the message data being split into user data and control data and each data storage area comprising a first partial storage area for saving user data and a second partial storage area for saving control data.

7. The method according to claim 6, wherein the user data are stored on all server units in a synchronized manner.

8. The method according to claim 6, wherein the user data is stored in the data storage area of each server unit separately from the control data.

15. The method according to claim 6, further comprising:

splitting the incoming data flows into user data and control data.

16. The method according to claim 6, further comprising:

providing message files as user data.

17. A computer readable medium comprising processor executable instructions to perform the steps of claim 6.
