Distributed Connection Management Architecture for Optimal VPC Provisioning on Hierarchical ATM Transport Network

Abstract

It was impossible to find a globally optimal route on hierarchical transport network because of the successive subnetwork partitioning and network topology abstraction. So, this paper proposes a hierarchical routing model that provides a globally optimal route on hierarchical ATM transport network. In addition, this paper proposes distributed connection management architecture adopting the proposed routing model. The hierarchical routing model and the distributed connection management architecture are specified in terms of information, computational and engineering viewpoints of RM-ODP. We implement the proposed routing model and the distributed connection management architecture, and show that the proposed connection management architecture always provides a globally optimal route with admissible performance by empirical performance analysis.

“…Networking means providing communication channels or circuits through which data are transferred between the named source and destination points, in accordance with the requirements of the subscribers. 13 To support such a networking concept, we define five functional categories: (1) …”

“…ITU-T G.805 partitioning concept is to define the management hierarchy to maximize the manageability and scalability. 8 A layer network can be partitioned into a number of management domains, sub-networks (SNWs) connected by topological links (TLs). Each SNW can be successively decomposed into smaller SNW that is equivalent to an ATM switch or a DSLAM.…”
