Abstract

A method for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data is provided. The method includes detecting a connection desiring access through the communication channel and assigning the connection to a group having arbitration parameters. Then, the method packetizes the data to be transmitted and transmits each packet of the data in time slices. In each time slice, data is transmitted using the arbitration parameters of the group.

Claims

1. A method for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data, comprising:

detecting a connection desiring access through the communication channel;

assigning the connection to a group having arbitration parameters, wherein the arbitration parameters are dynamically updateable in runtime;

packetizing the data to be transmitted; and

transmitting each packet of the data in time slices, in each time slice, using the dynamically updated arbitration parameters currently assigned to the group,

wherein the arbitration parameters are configured to dynamically change for each packet transmission of a time slice enabling efficient management of available channel bandwidth.

2. A method for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 1, further comprising:

updating the arbitration parameters; and

transmitting a next packet in a next time slice using the updated arbitration parameters.

3. A method for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 1, wherein the communication channel has a defined bandwidth.

4. A method for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 1, further comprising:

detecting additional connections desiring access through the communication channel;

assigning each connection to the group or additional groups, each group having defined arbitration parameters, and continuing to transmit each packet of the data in time slices, and in each time slice using the arbitration parameters assigned to the group in which the connection is a member.

5. A method for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 1, wherein the arbitration parameters define one of an allocated bandwidth and an assigned priority.

6. A method for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 5, wherein each of the allocated bandwidth and the assigned priority are updateable for each group.

7. A method for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 1, wherein the connection is between a client application and a server application.

8. A method for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 1, wherein the client application is a carlet of a telematics client, and the server application is an application of a telematics provisioning server.

9. A system for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data, comprising:

a grouping mechanism for creating connection groups, each connection group having specific arbitration parameters;

an arbitrator for managing the arbitration parameters of each connection group, the arbitration parameters being dynamically updateable in runtime; and

a data multiplexer and flow controller for transmitting the data, the transmitting includes packetizing the data and sending packets in time slices, and for each connection and in each time slice, using the specific dynamically updated arbitration parameters currently assigned to the connection group of the connections,

wherein the arbitration parameters are configured to dynamically change for each packet transmission of a time slice enabling efficient management of available channel bandwidth.

10. A system for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 9, further comprising:

a stream manager for initiating a logical connection between a client application and a server application over the communications channel.

11. A system for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 10, further comprising:

a protocol for synchronizing arbitrated bandwidth between the client application and the server application.

12. A system for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 9, wherein an update in the arbitration parameters causes a change in the handling of a next packet of data in a next time slice at runtime.

13. A system for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 10, wherein the system for arbitrating channel bandwidth is part of a telematics client framework.

14. A system for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data as recited in claim 13, wherein the telematics client framework processes for the client application and communicates with a telematics provisioning server that processes the server application.

15. A computer readable media in which program instructions are stored, which instructions, when read by a computing system, cause the computing system to perform a method for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data, the method comprising:

creating connection groups, each connection group having specific arbitration parameters;

managing the arbitration parameters of each connection group, the arbitration parameters being dynamically updateable in runtime; and

transmitting the data, the transmitting includes packetizing the data and sending packets in time slices, and for each connection and in each time slice, using the specific dynamically updated arbitration parameters currently assigned to the connection group of the connection,

wherein the arbitration parameters are configured to dynamically change for each packet transmission of a time slice enabling efficient management of available channel bandwidth.

16. The computer readable media as recited in claim 15, further comprising:

initiating a logical connection between a client application and a server application over the communications channel.

17. The computer readable media as recited in claim 16, further comprising:

synchronizing arbitrated bandwidth between the client application and the server application.

18. Computer readable media as recited in claim 15, wherein an update in the arbitration parameters causes a change in the handling of a next packet of data in a next time slice at runtime.

19. A method for arbitrating channel bandwidth among a plurality of logical connections desiring access over a communication channel to transmit data, the method comprising:

creating connection groups, each connection group having specific arbitration parameters;

managing the arbitration parameters of each connection group, the arbitration parameters being dynamically updateable in runtime; and

transmitting the data, the transmitting includes packetizing the data and sending packets in time slices, and for each connection and in each time slice, using the specific dynamically updated arbitration parameters currently assigned to the connection group of the connection,

wherein the arbitration parameters are configured to dynamically change for each packet transmission of a time slice enabling efficient management of available channel bandwidth.

20. A method as recited in claim 19, further comprising:

synchronizing arbitrated bandwidth between the client application and the server application.

21. A method as recited in claim 19, wherein an update in the arbitration parameters causes a change in the handling of a next packet of data in a next time slice at runtime.
