一种基于损失率估算的可变缓冲管理模型

缓冲区作为一种缓存关键信息、协调速度差异的重要手段，在计算机工程领域一直扮演着一个不可忽视的角色。缓冲区的大小对其作用的发挥至关重要。为此，在分析现有缓冲技术的基础上，提出了一种基于损失率估算的可变缓冲管理模型。该模型将缓冲区拥塞视为顾客损失，建立M/M/I/K损失排队系统，根据实时变化的数据流速率和有效处理能力，周期性计算、调整缓冲区大小，以提高资源利用率并保障缓冲区通畅。

A Variable Buffer Management Model Based on Loss-rate Estimate

Buffer,as an important tool that is used to store temporarily the key information and to deal with speed difference,always plays a vital role in computer engineering field.Buffer size is very important to its performance.So,after current buffer technologies are analyzed,this paper puts forward to a variable buffer management model based on loss-rate estimate(VBMMBLE).The VBMMBLE looks buffer congestion as client loss to build M/M/1/K queue system.Based on M/M/1/K queue system,it periodically calculates and adjusts buffer size to improve resource-utilization-rate and keep buffer expedite.
