The use of synthetic self-similar traffic in computer networks simulation is of vital importance for the capturing and reproducing of actual Internet data traffic behavior. A commonly used technique for generating selfsimilar traffic is achieved by aggregating On/Off sources where the active (On) and idle (Off) periods exhibit heavy tailed distributions. This work analyzes the balance between a...

OBJECTIVE To examine the association between drinking patterns and alcohol-related traffic casualties. STUDY DESIGN Data linkage of cross-sectional survey data on alcohol consumption with official traffic casualty records. METHODS Alcohol consumption measures for usual heavy drinking and risky single occasion drinking were derived for different time segments of the day from a 7-day drinking...

This paper proposes a new class of traffic profiles that is better suited for metering bursty Internet traffic streams than the traditional token bucket profile. A good traffic profile should satisfy two criteria: first, it should consider packets from a conforming traffic stream as in-profile with high probability to ensure a strong QoS guarantee; second, it should limit the network resources ...

Synthetic self-similar traffic in computer networks simulation is of imperative significance for the capturing and reproducing of actual Internet data traffic behavior. A universally used procedure for generating self-similar traffic is achieved by aggregating On/Off sources where the active (On) and idle (Off) periods exhibit heavy tailed distributions. This work analyzes the balance between a...

In this paper we investigate Gaussian queues in the light-traffic and in the heavy-traffic regime. The setting considered is that of a centered Gaussian process X ≡ {X(t) : t ∈ R} with stationary increments and variance function σ X(·), equipped with a deterministic drift c > 0, reflected at 0: Q (c) X (t) = sup −∞<s≤t (X(t)−X(s)− c(t− s)). We study the resulting stationary workload processQ (c...

Previous studies of Internet traffic have shown that a very small percentage of flows consume most of the network bandwidth. It is important to understand the characteristics of such flows for traffic engineering and modeling purposes. Several prior researchers have characterized such flows using different classification schemes: by size as elephant and mice; by duration as tortoise and dragonf...

The paper develops the mathematics of the heavy traac approach to the control and optimal control problem for multiplexing systems, where there are many mutually independent sources which feed into a single channel via a multiplexer (or of networks composed of such subsystems). Due to the widely varying bit rates over all sources, control over admission , bandwidth, etc., is needed to assure go...

Recent traffic measurement studies suggest that self-similarity observed in network traffic, and give some results by domestrating and simulating of TCP traffic in network. In this paper, we use network simulator to model aggregating general ON/OFF data source combinations of heavy tailed , establish the simulation based on UDP traffic. After analysis of result, we show self-similarity can be a...
