Service curves in Network Calculus: dos and don’ts
نویسندگان
چکیده
This report is a survey about service curves used in envelope-based models for worstcase performance evaluation, like Network Calculus or Real-Time Calculus. In a first part, we compare different models and their notions of service curves by establishing a hierarchy and similarities between different types of service curves and in a second part, we compare the behaviours of simple and strict service curves for concatenation and residual service curves.

A Mechanism for Detecting and Identifying DoS attack in VANET
VANET (Vehicular Ad-hoc Network) which is a hy- brid network (combination of infrastructure and infra- structure-less networks) is an emergent technology with promising future as well as great challenges especially in security. By the other hand this type of network is very sensible to safety problem. This paper focuses on a new mechanism for DoS (denial of service) attacks on the physical and ...

متن کاملComparison of different classes of service curves in network calculus
In envelope-based models for worst-case performance evaluation like Network Calculus or Real-Time Calculus, several types of service curves have been introduced to quantify some deterministic service guarantees. This paper studies the expressiveness of those different definitions of service curves. We revisit the hierarchy ranging from the most restrictive definition linked to variable capacity...
متن کاملA Calculus for End-to-end Statistical Service Guarantees
The deterministic network calculus offers an elegant framework for determining delays and backlog in a network with deterministic service guarantees to individual traffic flows. This paper addresses the problem of extending the network calculus to a probabilistic framework with statistical service guarantees. Here, the key difficulty relates to expressing, in a statistical setting, an end-to-en...
