In this tutorial, we will learn about the round-robin scheduling algorithm in an operating system with the help of an example.
轮询调度算法(Round-Robin Scheduling) 在多台机器实现负载均衡的时候,经常用到轮询调度算法(Round-Robin Scheduling)。 轮询调度算法就是以循环的方式依次将请求调度不同的服务器,即每次调度执行i = (i + 1) mod n,并选出第i台服务器。 算法的优点是其简洁性,它无需记录当前所有连接的状态,所以它是一种无状...
轮叫调度(Round Robin Scheduling)算法就是以轮叫的方式依次将请求调度不同的服务器,即每次调度执行i = (i + 1) mod n,并选出第i台服务器。算法的优点是其简洁性,它无需记录当前所有连接的状态,所以它是一种无状态调度。 在系统实现时,我们引入了一个额外条件,当服务器的权值为零时,表示该服务器不可用而...
操作系统综合题之“采用时间片轮转调度算法(Round-Robin,RR)执行,分时系统中的进程可能出现的状态变化” 一、问题:某分时系统中的进程可能出现下图所示的状态变化,请回答下列问题: 1.根据图示,您认为该系统采用的是什么进程调度策略? 2.把图中所示的每一个状态变化的原因填在下表相应位置。 变化 原因 1 2 3...

Existing round robin CPU scheduling algorithm cannot be implemented in real time operating system due to their high context switch rates, large waiting time, large response time, large turnaround time and less throughput. The proposed algorithm improves all the drawbacks of round robin CP U ...
Round Robin Scheduling is a pre-emptive scheduling algorithm that is used to schedule CPU utilization tasks, where each task is assigned a fixed time slot to execute known as quantum value. Once a task is executed for his assigned quantum value, it gets interrupted, and then the next task ...
The Preemptive Round Robin Scheduling Algorithm is an important scheduling algorithm used in both process scheduling and network scheduling. Processes are executed for a predefined unit of time called a quantum. Once the CPU executes the process for the specified time slice, the process either ...

轮询调度(Round Robin Scheduling)算法就是以轮询的方式依次将请求调度不同的服务器,即每次调度执行i = (i + 1) mod n,并选出第i台服务器。算法的优点是其简洁性,它无需记录当前所有连接的状态,所以它是一种无状态调度。 轮询调度算法的原理是每一次把来自用户的请求轮流分配给内部中的服务器,从1开始,直到...
