Summary :

This paper proposes an algorithm for cooperative control over both logical (switching) and physical (transmission) networks for multiservice environments. The control of the logical networks, which conduct traffic routing in response to demands for grades of service, is cooperatively performed with the control of the physical network, which allocates capacity based on the network topology and its resources. A case study is carried out to evaluate the usefulness of the proposed cooperative control method. The case study results show the proposed method provides grade of service satisfaction for a wider range of network condition and improvements in throughput compared with the separate logical or physical network control method. In addition, the application of the proposed control method to ATM networks is discussed.
