Abstract
A method and apparatus for transporting IP datagrams over SONET at a guaranteed quality of service are described. The method utilizes a multi-level bandwidth management hierarchy. A bandwidth allocation manager provides real time high level control of bandwidth allocation in each SONET domain. A bandwidth client at each node in the domain negotiates bandwidth requirements for IP services connected to the node. This enables low error bit rate, scalability and reliable service that can provide guaranteed quality of service for IP applications. All aspects of connection setup, bandwidth allocation, bandwidth size adjustment and connection termination are negotiated by the bandwidth client with the bandwidth allocation manager. Multiple domains can be interconnected to form larger networks providing reliable connections at a guaranteed QOS.
