However, at the influx peak, the server had thousands of players waiting in queue. [11] The queue gave earlier 2b2t players priority over newer players, [3] although this feature was removed after a year. [12] The regular queue moves slowly and can contain over a thousand players. [2] Waiting in the queue has been described as an onerous task ...
Queueing theory is the mathematical study of waiting lines, or queues. [1] A queueing model is constructed so that queue lengths and waiting time can be predicted. [1] Queueing theory is generally considered a branch of operations research because the results are often used when making business decisions about the resources needed to provide a ...

Processes in lower-priority queues are selected only when all of the higher-priority queues are empty. Waiting time and response time depend on the priority of the process. Higher-priority processes have smaller waiting and response times. Deadlines can be met by giving processes with deadlines a higher priority.
Earliest deadline first (EDF) or least time to go is a dynamic priority scheduling algorithm used in real-time operating systems to place processes in a priority queue. Whenever a scheduling event occurs (task finishes, new task released, etc.) the queue will be searched for the process closest to its deadline.
Low-latency queuing (LLQ) is a network scheduling feature developed by Cisco to bring strict priority queuing (PQ) to class-based weighted fair queuing (CBWFQ). LLQ allows delay-sensitive data (such as voice) to be given preferential treatment over other traffic by letting the data to be dequeued and sent first.
In general, a multilevel feedback queue scheduler is defined by the following parameters: [6] The number of queues. The scheduling algorithm for each queue which can be different from FIFO. The method used to determine when to promote a process to a higher priority queue. The method used to determine when to demote a process to a lower-priority ...
