Evaluation of a Real-Time Distribution Service
نویسندگان
چکیده
As control systems become more distributed and they are implemented with smaller hardware and software components, implementing the necessary communication links becomes challenging. There are considerable technical difficulties in guaranteeing upper bounds for latencies in motion or machine control, synchronizing the execution and communication of distributed components, taking corrective action in fault situations and reconfiguring the system. In this paper, we discuss the main communication requirements of distributed control systems and use them to evaluate a certain distribution service product.

متن کاملA Collaborative Blood Distribution System in a Network of Hospitals based on their Normal and Emergency Requests: a Mathematical Model and Solution
Background and Objectives: A blood distribution network orchestrates distribution of safe blood products to hospitals. Blood shortage and blood wastage are two important factors which may affect efficiency of blood distribution network. Service delivery time is another factor that refers to the time interval between blood request by a hospital and transfusing it to the patient....
متن کاملF-STONE: A Fast Real-Time DDOS Attack Detection Method Using an Improved Historical Memory Management
Distributed Denial of Service (DDoS) is a common attack in recent years that can deplete the bandwidth of victim nodes by flooding packets. Based on the type and quantity of traffic used for the attack and the exploited vulnerability of the target, DDoS attacks are grouped into three categories as Volumetric attacks, Protocol attacks and Application attacks. The volumetric attack, which the pro...
متن کاملA Non-Preemptive Two-Class M/M/1 System with Prioritized Real-Time Jobs under Earliest-Deadline-First Policy
This paper introduces an analytical method for approximating the performance of a two-class priority M/M/1 system. The system is fully non-preemptive. More specifically, the prioritized class-1 jobs are real-time and served with the non-preemptive earliest-deadline-first (EDF) policy, but despite their priority cannot preempt any non real-time class-2 job. The waiting class-2 jobs can only be s...
