sending a rejection message to the second computing device; and

determining, after receiving in response to the rejection message a new offer with a new set of quality of service parameters from the second computing device, whether the computing device is configured to transmit information compliant with the new set of quality of service parameters.

8. The non-transitory computer readable medium of claim 1 , wherein the instructions, when executed by the computing device, further cause the computing device to perform the operation of sending an offer confirmation message if the computing device is configured to transmit information compliant with quality of service parameters included in an offer message.

9. A method, comprising:

sending, from a first computing device, a first offer message including a first set of quality of service parameters and a keep alive interval for the first offer to a second computing device;

sending, after receiving an offer rejection message from the second computing device responsive to the first set of quality of service parameters being unacceptable, a second offer message, wherein the second offer message includes a second set of quality of service parameters and the keep alive interval;

receiving information compliant with the second set of quality of service parameters from the second computing device responsive to the second set of quality of service parameters being acceptable; and

sending, if the keep alive interval has expired, a new offer message, wherein the new offer message includes a new set of quality of service parameters and a new keep alive interval for the new offer; and

determining, if the keep alive interval has not expired, whether it is time to send a keep alive message from the second computing device, the keep alive message including an offer ID that was included with the second offer message;

generating, if it is time to send the keep alive message; and

sending, after the keep alive message is generated, the keep alive message to the first computing device.

10. The method of claim 9 , comprising receiving an offer confirmation message responsive to the second set of quality of service parameters being acceptable.

11. The method of claim 9 , comprising, until a set of quality of service parameters is acceptable, iteratively repeating:

receiving an offer rejection message; and

sending a new offer message including a new set of quality of service parameters responsive to a set of quality of service parameters being unacceptable.

12. The method of claim 9 , wherein receiving the offer rejection message includes receiving a cause code indicating which quality of service parameters are unacceptable.

13. The method of claim 9 , wherein the first set of quality of service parameters includes a maximum transmit unit size.

14. The method of claim 9 , wherein the first set of quality of service parameters includes a minimum transmission rate.
