This article provides an overview of ATT to an adaptive network that monitors, correlates, and takes action; to a cybernated network that has integrated components that dynamically manage by business rules and policies. We give several examples of ho

Using a client-server based signaling protocol, the authors propose a new approach to connection establishment that allows for the easy handling of multiparty connections and improves end-to-end connection setup delay by parallelizing certain operati

We present our simulation-based design of hierarchical routing systems using the following state parameters to support quality of service (QoS): delay, hop count, and available bandwidth. Without revealing its internal structure, a cluster in a hiera

In this paper, we consider retransmission-based error recovery schemes for broadband ISDN. Retransmission performance is affected by patterns of cell loss behaviour and by the amount of overhead required. In B-ISDN, data are transmitted in frames, ea

Private Network-Network Interface (PNNI) is a routing protocol standard developed by the ATM Forum for the connection-oriented ATM networking technology. Open Shortest Path First (OSPF) and Border Gateway Protocol (BGP) are the corresponding IETF sta

We present a graph-theoretic model of routing hierarchies that abstracts the generic properties of standard routing protocols such as PNNI and OSPF/BGP. These protocols are currently deployed in operational networks. Our model is based on purely topo

An analytical model is developed in this paper for evaluating the performance of bandwidth allocation algorithms, with or without preemption, when used for Diffserv-aware MPLS traffic engineering. It is shown that, a major difference between various
