Multi-level SchedulingPacket lossOne of the highly reliable protocol stack used in communication networking industry is TCP/IP Protocol suite. Due to the huge support from the customers communication sector grows tremendously, leading to many contributions from the academicians and industrialist. The ...
Rule 4: Once a job uses up its time allotment at a given level (regardless of how many times it has given up the CPU), its priority is reduced (i.e., it moves down one queue).

In multi-level queue scheduling, the starvation problem has been solved efficiently but this technique is not suitable for real time processes. To overcome this problem, an idea of new algorithm i.e., MLQPTS (Multilevel Queue with ... I Sattar,M Shahid,N Yasir 被引量: 3发表: 2014年 NE...
CPU Scheduling, RR scheduling, Multi Level Feedback Queue SchedulingpCPU scheduling is a vital phenomenon of operating system. At present, numerous CPU scheduling algorithms are existing like FCFS(First come first serve), SJF (shortest job first),SRTF( Shortest remaining time first) , Priority ...

Multi LevelDASALBESAResponse time is one of the characteristics of scheduler, happens to be a prominent attribute of any CPU scheduling algorithm. The proposed New Multi Level Feedback Queue [NMLFQ] Scheduler is compared with dynamic, real time, Dependent Activity Scheduling Algorithm (DASA) and...
In this paper we address the problem of optimal scheduling in a multi-queue single-server (MQSS) model. The server visits N queues in an arbitrary manner. Each queue is visited for a random period of time whose duration is sampled in advance. At the end of a visit period, either all ...
How do I make both queues and both channels work? Or use the same queue and channel, but so that it does not get stuck if sending started simultaneously in both a loop and an interrupt?
An advanced multi-level feedback queue is specified in PintOS document for scheduling the threads. A thread exhausting its allocated time-quantum is pushed lower in the priority hierarchy. The penalty is then decayed over time. The guidance, provided here, implements the exercise as a single ...
