Traffic modeling and classification finds importance in many areas such as bandwidth management, traffic analysis, traffic prediction, network planning, Quality of Service provisioning and anomalous traffic detection. Network traffic exhibits some statistically invariant properties. Earlier works show that it is possible to identify traffic based on its statistical characteristics. In this pape...

The ever-increasing growth of the current Internet traffic volume is demanding a bandwidth which can only be satisfied by means of optical technology. However, while WDM networks will bring an unprecedented amount of available bandwidth, traffic management techniques become necessary in order to make this bandwidth readily available to the end user. In this chapter we provide an overview of tra...

With the growing interest in the railway sector, mainly because of energetic reasons, there is also a need to increase the efficiency of the railway lines. One way to optimize this sector is to improve quality in the train control process itself. Nowadays, train dispatching is still mostly done by human operators that use elementary tools and thereby solving conflicts sub-optimally. Motivated b...

This study uses regression analysis to evaluate long-run traffic management system performance. Three important traffic management systems in the Twin Cities metro area—Ramp Metering, Variable Message Signs, and Freeway Service Patrols (the Highway Helper Program) were evaluated using multiple regression models to predict link speed and incident rate. We find that ramp meters increase freeway l...

The paper shows the state of the art of the development of systems capable to reason about the traffic behavior and evolution in similar terms to an expert traffic operator. This type of systems may not be conceived to replace the human operator but to act as intelligent assistants that cooperate in the task of defining and applying traffic control decisions. Such concept of system is that of t...

We propose a systematic means for achieving a set of overall traac management or planning goals with respect to the performance of the traac network through the use of link tolls. The primary goals are deened by a set of link ow restrictions. The tolls that achieve these goals are obtained by solving a generalization of the classical user equilibrium model which includes a set of side constrain...

Network resources are shared as needed by a community of users. Without effective traffic controls, networks are vulnerable to possible congestion when the offered traffic exceeds the network capacity, leading to serious deterioration of network performance. This chapter gives an overview of traffic control methods and their underlying principles. The main preventive controls are admission cont...

When the TCP and IP protocols were first proposed the emphasis was on a simple best-effort service. Later on TCP was modified in order to address the issue of congestion control, that is to make sure that the senders would not overwhelm the network by sending data too fast. Over the years these protocols have shown an excellent scalability and have allowed the Internet to grow from a network co...

This paper proposes an integrated traffic engineering and management system for DiffServ-over-MPLS services in Next Generation Internet (NGI). Using the proposed traffic engineering functions for DiffServover-MPLS network, the Internet service provider (ISP) can easily configure Diffserv-over-MPLS traffic flows among customer’s distributed sites, and can provide guaranteed end-to-end QoS by con...
