Patent ID: 8391292

Claim:
A method for dynamically adjusting quality of service (QoS) parameters associated with a virtual circuit comprising a first end connected to a first router and a second end connected to a second router, the method comprising: sending an offer message to the second router from the first router, wherein sending the offer message includes sending at least a first set of QoS parameters, an offer ID identifying the offer containing the first set of QoS parameters and a keep alive interval for the offer; receiving an offer rejection message from the second router at the first router, wherein the offer rejection message comprises the offer ID; and sending a new offer message to the second router, wherein the new offer message include at least a second set of QoS parameters and a new offer ID, the new offer ID being different from the offer ID, wherein the new offer ID identifies the new offer containing the second set o QoS parameters; and receiving information compliant with the second set of QoS parameters at the first router.
