An increasing number of systems have been proposed or deployed to the transit core of the Internet with the goal of observing and manipulating traffic in flight, systems we term Traffic Manipulating Boxes. Examples of these include: decoy routing systems, surveillance infrastructure like the NSA’s alleged QUANTUM project, and traffic shaping middleboxes. In this work, we examine a new approach ...

LambdaGrid applications are likely to be the first users of terabit-level networking. The challenge of terabit networking will be how to manage traffic at the edges. This paper provides insight into the traffic characteristics of future terabit applications, and uses this to drive the design of an edge-based architecture called LambdaBridge. LambdaBridge will provision and control predictable-p...

A system consisting of two buffers, each with independent fluid sources, is considered in this paper. Due to ease of implementation, the output capacities for the two buffers depend on the workload of only one of the buffers that is measured. A threshold-based policy is considered to dynamically assign output capacities for both buffers. Marginal workload distributions for the two buffers need ...

Earthquakes are among those natural hazards which may lead to disruption in the function of arterial traffic routes. Road networks are particularly vulnerable, due to their geographical dispersion, extensive functions and structural reliance on favourable geophysical conditions. Traffic functionality after a natural disaster and the repair/rehabilitation cost of roads are crucial considerations...

We present an overview over recent developments of traffic flow models for production networks. Particular emphasis is given to the implementation of service rules for complex systems, involving multiple product types and re entrant loops. A rather general scheduling concept is introduced and demonstrated on some numerical experiments.

Simulation is a widely used method for the performance analysis Jain, 1991 of communication systems. There is a large number of various methods used to describe the behaviour of complex systems. Banks et al., 1996; Bratley et al., 1986; Jávor, 1985; Jávor, 1993 The simulation of large and complex systems requires a large amount of memory and computing power that is often available only on a sup...

Statistical mechanics of a small system of cars on a single-lane road is developed. The system is not characterized by a Hamiltonian but by a conditional probability of a velocity of a car for the given velocity and distance of the car ahead. Distribution of car velocities for various densities of a group of cars are derived as well as probabilities of density fluctuations of the group for diff...

In analogy to the ow of uids, it is expected that the aggregate density and the velocity of vehicles in a section of a freeway adequately describe the tra c ow dynamics. The conservation of mass equation together with the aggregation of the vehicle following dynamics of controlled vehicles describes the evolution of the tra c density and the aggregate speed of a tra c ow. There are two kinds of...

in recent years due to improvements of technology within automobile industry, design process of advanced driver assistance systems for collision avoidance and traffic management has been investigated in both academics and industrial levels. detection of traffic signs is an effective method to reach the mentioned aims. in this paper a new intelligent driver assistance system based on traffic sig...
