Gentle-BLUE: A New Method for Active Queue Management

Active queue management algorithm for time delay demand

“…为了使端到端的延迟下降, 并同步提高网络的吞吐量, BLUE 算法被提出, 它是一种以链路空闲和缓冲区溢出事件作为拥塞度量的队列管理方法 [7] . 为了提高算法的稳定性, 克 服网络拥塞反应迟缓等缺点, 避免突发数据流量到来时造成的网络性能下降, Alsaaidah 等 [8] 提出了 Gentle-BLUE 算法, 其使用两个参数, 将队列长度作为依据, 在拥塞发生前动态地调整丢弃概率.…”

Markov-Modulated Bernoulli-Based Performance Analysis for Gentle BLUE and BLUE Algorithms under Bursty and Correlated Traffic

“…GB (Alsaaidah et al, 2014) extends the well-known BLUE algorithm (Feng et al, 2002) by providing a dynamic mechanism to calculate DP value based on the queue length status. GB is proposed with the response to the limitation of BLUE algorithm.As such, BLUE algorithm calculates DP using a fixed value while GB calculates the DP dynamically.…”

“…Initially, the queue length is empty, which means the initial value of queue length is zero and the packet will be arrived initially to state 1, thus the initial state is state 1. The initial DP (initDP) parameter is set to a value similar to the original BLUE (Feng et al, 2002) and original GB (Alsaaidah et al, 2014).…”

“…For the purpose of overcoming these disadvantages in DT, Active Queue Management (AQM) algorithms have been developed. Examples of AQM algorithms are, BLUE (Feng et al, 2002), Random Early Detection (RED) (Floyd and Jacobson, 1993), dynamic Gentle Random Early Detection DGRED (Baklizi et al, 2013), adaptive RED (Floyd et al, 2001), Distortion Constrained (DC) (Ghoreishi et al, 2015), Enhancement of Fair Random Early Detection Algorithm (EFRED) (Abdulkareem et al, 2015) and Gentle BLUE (GB) (Alsaaidah et al, 2014).…”

“…The ultimate goal of using queue modeling is to evaluate or validate the performance. Models, such as the renewal traffic (Bernoulli Process (BP), Poisson Processes (PPs)) and Markov modulate arrival such as Markov-Modulated Bernoulli Arrival Process (MMBP) (Lim et al, 2010;Alsaaidah et al, 2014), can be used. Several AQM algorithms have been evaluated based on BP, which is a discrete time process that deals with network traffic as a single class.…”
