Abstract
A method and system for establishing a guaranteed quality of service (QoS) Internet protocol (IP) connection between an first bridging device and a second bridging device through a switched transport network. The second bridging device receives a first signaling message from the first bridging device through an IP network, the first signaling message containing at least one parameter defining a predefined quality of service. In response, the second bridging device associates the first bridging device's switched transport network address and IP address, without communicating with an address server. The second bridging device directs a second signaling message to the switched transport network of address of the first bridging device, which establishes the IP connection between the first bridging device and the second bridging device through the switched transport network. The IP connection is in accordance with the at least one quality of service parameter contained in the second signaling message.
