Network management with bounded flooding routing algorithm to ensure IP QoS over ATM virtual path network

To meet the upcoming demands of reliable delivery of QoS guaranteed multimedia IP traffic over a large-scale ATM network, this paper proposes two algorithms. One is a bounded flooding routing algorithm (BFRA) that provides a globally optimal VPC to deploy a IP network over a G.805-based hierarchical ATM VP transport network, which was impossible because of a successive network topology abstraction or aggregation. The other is the ATM VPC reconfiguration algorithm (AVRA) to cope with IP network performance degradation that is mainly caused by increase of traffic load or transit delay of the IP network and the ATM VPC abnormality of ATM VP network. This paper describes an implementation model of ATM VP network management system (ATM VP-NMS) to maximize the performance of VPC provisioning and reconfiguration and to ensure unceasing VPC management. This paper also describes the empirical performance analysis of the proposed BFRA and AVRA by implementation using CORBA from the perspectives of the routing table construction, VPC provisioning and VPC reconfiguration.
