In this paper we survey all kinds of scheduling algorithms for queues of the output port in a router or switch. We firstly overview the important disciplines for scheduling algorithms, discuss their properties, complexities, implementations and applications by classification. Several practical algorithms ...
A major problem with priority-scheduling algorithms is indefinte blockhing(or starvation). In a heavlly loaded computer system, a steady stream of higher-priority processes can prevent a low-priority process from ever getting the CPU. A solution to the problem of indefinite blockage of low-pri...
6.13 In Chapter 5, we discussed possible race conditions on various kernel data structures. Most scheduling algorithms maintain arun queue, which lists processes eligible to run on a processor. On multicore systems, there are two general options: (1) each processing core has its own run queue,...
Although there are a number of packet scheduling algorithms that have been proposed in the literature, the design of those algorithms is challenged by need for supporting different levels of services, fairness, and implementation complexity and so on. Scheduling and resource allocation are essential ...
Shift schedulingPersonnel capacity planningThis chapter discusses the challenges of workforce scheduling in systems with time-varying arrival rates, with customer impatience (abandonments), general service and abandonment distributions and an exhaustive end-of-shift policy (servers may work overtime at the...
Multiple queues are maintained for processes with common characteristics. Each queue can have its own scheduling algorithms. Priorities are assigned to each queue. For example, CPU-bound jobs can be scheduled in one queue and all I/O-bound jobs in another queue. The Process Scheduler then altern...
Queues can be optimized byusing various scheduling algorithms depending upon the performance criteria to be improved e.g. response time, throughput. The work has been done in MATLAB using the parallel computing toolbox.doi:10.5121/ijgca.2012.3405Rosemarry, Pinky...
