摘要
设计一个分布式并行服务器,必需全面考虑网络层和应用层流量以及响应特性对性能的影响。分布式并行服务器模型(DPS)具有良好的响应特性和较强的服务能力,对它进行了全面的分析,重点研究了网络层流量对模型性能的影响,并且在理论分析和实验测试的基础上,将网络层流量和应用层流量按协议栈分布式处理,提出了改进的DPS模型。改进的DPS模型能够更好的处理网络层流量,有效地改善模型的性能。
To design an effective distributed parallel server, the two principal metrics of networking should necessarily be considered： throughput and delay of both network layer and application layer to improve the original power of the network. Distributed Parallel Server （DPS） is characterized by the response characteristic and service capability of distributed parallel server. This paper makes an in-depth study on DPS, and based on the analysis and experiments it introduces an intermedium in DPS, namely distribution device, to partition flux in network layer according to working ability of application server. Consequently performance is improved.
