Abstract

The invention relates to a device, system and method a method for applying a certain Quality of Service (QoS) to a data stream (31a-31c, 32a-32b, 33a) of an application (31-33) communicating data over a sockets connection. The method comprises providing a uniquely identifiable identifier (UID, Stream Type) the application (31-33) or to the data stream (31a-31c, 32a-32b, 33a) from or to the application, and associating said identifier (UID, Stream Type) with a particular QoS in order to apply the particular QoS to the particular application (31-33) or to the particular data stream (31a-31c, 32a-32b, 33a), which application or data stream is identified by the identifier.

Claims

1. A method for applying a certain Quality of Service (QoS) to a data stream of an application communicating data over a sockets connection, wherein the method comprises

providing a uniquely identifiable identifier (UID, Stream Type) to at least one of the application and the data stream from or to the application, and

associating said identifier (UID, Stream Type) with a particular QoS in order to apply the particular QoS to said at at least one of the particular application and the particular data stream, which application or data stream is identified by the identifier.

2. A method according to

claim 1

, wherein the method comprises transferring the identifier (UID, Stream Type) over the sockets connection.

3. A method according to

claim 1

, wherein the method further comprises

providing a socket application program interface to the application,

establishing a socket for transfer of the data stream, and

transferring the identifier (UID, Stream Type) over the socket application program interface to uniquely identify said at least one of the particular application and the particular data stream, which application or data stream is identified by the identifier, in order apply the particular QoS to the data stream being communicated over the sockets connection.

4. A device comprising

an application program for executing a particular application, and

means for communicating data over a sockets connection, wherein the device further comprises

means for providing a uniquely identifiable identifier (UID, Stream Type) to at least one of the application and the data from or to the application, and

means for associating said identifier (UID, Stream Type) with a particular QoS in order to apply the particular QoS to said at least one of the particular application and the particular data, which application or data is identified by the identifier.

6. A device according to

claim 4

or

5

, wherein the device further comprises

means for providing a socket application program interface to the application,

means for establishing a socket for transfer of the data, and

means for transferring the identifier (UID, Stream Type) over the socket application program interface to uniquely identify said at least one of the particular application and the particular data, which application or data is identified by the identifier, in order apply the particular QoS to the data being communicated over the sockets connection.

5. A device comprising

an application program for executing a particular application, and

means for communicating data over a sockets connection, wherein the device further comprises

means for associating a centrally defined identifier (UID, Stream Type), which identifies at least one of the application and the data from or to the application, with a particular QoS in order to apply the particular QoS to said at least one of the particular application and the particular data, which application or data is identified by the identifier.

7. A computer program product for an electronic device having an application to communicate data over a sockets connection, wherein in that the computer program product comprises

computer program means for providing a uniquely identifiable identifier (UID, Stream Type) to at least one of the application and the data from or to the application, and

computer program means for associating said identifier (UID, Stream Type) with a particular QoS in order to apply the particular QoS to said at least one of the particular application and the particular data, which application or data is identified by the identifier.

8. A computer program product according to

claim 7

, wherein the computer program product further comprises

computer program means for providing a socket application program interface to the application,

computer program means for establishing a socket for transfer of the data, and

computer program means for transferring the identifier (UID, Stream Type) over the socket application program interface to uniquely identify said at least one of the particular application and the particular data, which application or data is identified by the identifier, in order apply the particular QoS to the data being communicated over the sockets connection.
