Patent ID: 8305893

Claim:
A method of establishing end-to-end Quality of Service (QoS) in a single end-to-end connection between a local device in a local network and a remote device in a remote network, the method comprising: receiving total end-to-end QoS requirements for a connection between a local device in a local network and a remote device in a remote network; requesting that a QoS connection for a segment of the connection between the local device and a local gateway in the local network be established, based on the total end-to-end QoS requirements; computing remaining QoS requirements by deducting actual QoS assigned for the QoS connection for the segment of the connection between the local device and the local gateway from the total end-to-end QoS requirements; requesting that a QoS connection for a segment of the connection between the remote device and a remote gateway in the remote network be established, using the remaining QoS requirements so that the QoS assigned for the QoS connection for the segment of the connection between the remote device and the remote gateway is based upon the actual QoS assigned for the QoS connection for the segment of the connection between the local device and the local gateway, and such that the QoS assigned for the QoS connection for the segment of the connection between the remote device and the remote gateway is different than actual QoS assigned for the QoS connection for the segment of the connection between the local device and the local gateway, and requesting to configure a QoS connection between the local gateway and the remote gateway.
