Abstract

An approach is provided for providing quality of service reservations in a packet-based radio communication network is disclosed. Connection information including connection rate is extracted from a dataflow from an application requesting connection-oriented service. A request message is sent to a proxy for establishing a connection based on the connection information over the network, wherein the proxy configures a classification rule based on flow criteria from the request message and accordingly initiates establishment of the connection over the network to a destination terminal. A confirmation that the connection can be established is selectively received according to the connection information, wherein the dataflow satisfying the flow criteria from the application is transported over the established connection to the destination terminal. This approach as particular applicability to shared capacity systems, such as a satellite communication system.

Claims

1. A method for providing quality of service reservations in a packet-based radio communication network, the method comprising:

extracting connection information including connection rate from a dataflow from an application requesting connection-oriented service;

sending a request message to a proxy for establishing a connection based on the connection information over the network, wherein the proxy configures a classification rule based on flow criteria from the request message and accordingly initiates establishment of the connection over the network to a destination terminal; and

selectively receiving confirmation that the connection can be established according to the connection information, wherein the dataflow satisfying the flow criteria from the application is transported over the established connection to the destination terminal.

2. A method according to claim 1, wherein the radio communication network includes a satellite configured to process packets in support of the connection-oriented service, and the proxy is resident within a satellite terminal of the network.

3. A method according to claim 2, further comprising:

receiving a connection identifier from a control hub within the satellite network, wherein the proxy initiates the establishment of the connection based on the connection identifier.

4. A method according to claim 2, wherein the connection is a multicast connection, the method further comprising:

forwarding the dataflow to the satellite for replication.

5. A computer-readable medium bearing instructions for providing quality of service reservations in a packet-based radio communication network, the instructions being arranged, upon execution, to cause one or more processors to perform the step of a method according to claim 1.

6. A system for providing quality of service reservations in a packet-based radio communication network, the system comprising:

means for extracting connection information including connection rate from a dataflow from an application requesting connection-oriented service;

means for sending a request message to a proxy for establishing a connection based on the connection information over the network, wherein the proxy configures a classification rule based on flow criteria from the request message and accordingly initiates establishment of the connection over the network to a destination terminal; and

means for selectively receiving confirmation that the connection can be established according to the connection information, wherein the dataflow satisfying the flow criteria from the application is transported over the established connection to the destination terminal.

7. A method for providing quality of service reservations in a packet-based radio communication network, the method comprising:

receiving a request message for establishing a connection over the network based on connection information, which includes connection rate, extracted from a dataflow associated with an application requesting connection-oriented service, the request message specifying flow criteria;

configuring a classification rule based on the flow criteria from the request message;

initiating establishment of the connection over the network to a destination terminal;

determining whether the connection can be satisfied; and

selectively forwarding confirmation that the connection can be established based on the determination, wherein the dataflow satisfying the flow criteria from the application is transported over the established connection to the destination terminal.

8. A method according to claim 7, wherein the radio communication network includes a satellite configured to process packets in support of the connection-oriented service.

9. A method according to claim 8, wherein the establishment of the connection in the initiating step is based on a connection identifier transmitted by a hub within the satellite network.

10. A method according to claim 8, wherein the connection is a multicast connection, the method further comprising:

forwarding the dataflow to the satellite for replication.

11. A computer-readable medium bearing instructions for providing quality of service reservations in a packet-based radio communication network, the instructions being arranged, upon execution, to cause one or more processors to perform the step of a method according to claim 7.

12. A system for providing quality of service reservations in a packet-based radio communication network, the system comprising:

means for receiving a request message for establishing a connection over the network based on connection information, which includes connection rate, extracted from a dataflow associated with an application requesting connection-oriented service, the request message specifying flow criteria;

means for configuring a classification rule based on the flow criteria from the request message;

means for initiating establishment of the connection over the network to a destination terminal;

means for determining whether the connection can be satisfied; and

means for selectively forwarding confirmation that the connection can be established based on the determination, wherein the dataflow satisfying the flow criteria from the application is transported over the established connection to the destination terminal.

13. A network device for providing quality of service reservations in a packet-based radio communication network, the device comprising:

an interface configured to receive a dataflow from an application requesting connection-oriented service; and

a processor coupled to the interface and configured to extract connection information including connection rate from the dataflow, and to send a request message to a proxy for establishing a connection based on the connection information over the network, the proxy being configured to set a classification rule based on flow criteria from the request message and to accordingly initiate establishment of the connection over the network to a destination terminal, the interface selectively receiving confirmation that the connection can be established according to the connection information, wherein the dataflow satisfying the flow criteria from the application is transported over the established connection to the destination terminal.

14. A device according to claim 13, wherein the radio communication network includes a satellite configured to process packets in support of the connection-oriented service, and the proxy is resident within a satellite terminal of the network.

15. A device according to claim 14, wherein a connection identifier is received from a control hub within the satellite network, and the proxy initiates the establishment of the connection based on the connection identifier.

16. A device according to claim 14, wherein the connection is a multicast connection, and the dataflow is forwarded to the satellite for replication.

17. A terminal for providing quality of service reservations in a packet-based radio communication network, the terminal comprising:
