The Fundamental Role of Teletraffic in the Evolution of Telecommunications Networks


Book Description

The International Teletraffic Congress (ITC) is a recognized international organization taking part in the work of the International Telecommunications Union. The congress traditionally deals with the development of teletraffic theory and its applications to the design, planning and operation of telecommunication systems, networks and services. The contents of ITC 14 illustrate the important role of teletraffic in the current period of rapid evolution of telecommunication networks. A large number of papers address the teletraffic issues behind developments in broadband communications and ATM technology. The extension of possiblities for user mobility and personal communications together with the generalization of common channnel signalling and the provision of new intelligent network services are further extremely significant developments whose teletraffic implications are explored in a number of contributions. ITC 14 also addresses traditional teletraffic subjects, proposing enhancements to traffic engineering practices for existing circuit and packet switched telecommunications networks and making valuable original contributions to the fundamental mathematical tools on which teletraffic theory is based. The contents of these Proceedings accurately reflect the extremely wide scope of the ITC, extending from basic mathematical theory to day-to-day traffic engineering practices, and constitute the state of the art in 1994 of one of the fundamental telecommunications sciences.




Dynamic Routing in Broadband Networks


Book Description

Dynamic Routing in Broadband Networks focuses on routing in broadband networks based on MPLS (Multiprotocol Label Switching) and ATM (Asynchronous Transfer Mode). The routing methods are based on the theory of Markov decision processes which forms a very accurate framework for on-line route optimization. The author shows the issue of performance optimization and scalability with respect to dynamic routing of logical connections in broadband networks. The methods used are applicable to routing virtual path connections (VPC) and virtual channel connections (VCC) in ATM networks as well as label switched paths (LSP) in MPLS networks. Simulation results and a performance comparison with reference routing are given for the different schemes.

Traffic Engineering and QoS Optimization of Integrated Voice and Data Networks


Book Description

This book describes, analyzes, and recommends traffic engineering (TE) and quality of service (QoS) optimization methods for integrated voice/data dynamic routing networks. These functions control a network's response to traffic demands and other stimuli, such as link failures or node failures. TE and QoS optimization is concerned with measurement, modeling, characterization, and control of network traffic, and the application of techniques to achieve specific performance objectives. The scope of the analysis and recommendations include dimensioning, call/flow and connection routing, QoS resource management, routing table management, dynamic transport routing, and operational requirements. Case studies are included which provide the reader with a concrete way into the technical details and highlight why and how to use the techniques described in the book. Includes Case Studies of MPLS and GMPLS Network Optimization Presents state-of-the-art traffic engineering and quality of service optimization methods and illustrates the tradeoffs between the various methods discussed Contains practical Case Studies based on large-scale service provider implementations and architecture plans Written by a highly respected and well known active expert in traffic engineering and quality of service




Dynamic Call Routing in Circuit-switched Telecommunication Networks


Book Description

Abstract: "In this paper, maximum capacity routing in a directed graph is used as the framework for a study of procedures for computing routing tables for the stored program control switches in a circuit-switched telecommunication network that generate least-busy circuit-free (tandem) paths for all origin-destination pairs of switches. Such paths are the basis for the dynamic selection of overflow routes in a dynamic call routing strategy like Dynamically Controlled Routing and must be computed periodically, almost on the time scale of call arrivals. Several efficient sequential solutions are presented, focusing on their complexity. One of the algorithms also computes routing tables that allow for controlling the amount of transmission resources occupied by a call."
