【摘要】：当今网络通信技术的飞速发展不仅带来了社会的进步,更极大地丰富了人们的日常生活,然而不断扩增的网络用户及日趋庞大的网络规模,给传统网络服务器带来了严峻的挑战,譬如网络信息拥塞以及网络服务超载等问题成为影响网络服务器性能的重要因素。为了有效解决上述问题,提升网络服务器性能,本文提出了一种商空间下的网络服务器跨层优化设计,分别从结构以及算法两个方面着重对网络服务器进行设计优化,研究工作主要从以下几个方面进行:首先,阐述了网络服务器性能研究的发展背景、重要意义以及国内外研究现状,并指出当前网络服务器性能优化存在的两大问题,即网络结构适应性不强和调度算法亟待优化,以此作为本论文研究的出发点。其次,对本文中涉及的商空间理论和跨层技术着重进行了研究,对其特性优点、常用理论和实现方法进行归纳总结,并针对网络服务器存在的性能问题,从架构和算法优化两个方面出发,给出了基于商空间理论的服务器跨层设计和路由路径规划算法,并以OPNET Modeler作为网络仿真平台,对本文所设计的服务器优化模型进行仿真建模,并针对网络服务器跨层优化模型设计了从服务器到用户的端对端通信网络,通过配置网络业务、控制网络参数等手段模拟服务器高负载环境,验证了商空间下的网络服务器跨层优化技术及其可行性。最后,本文对实验数据进行分析总结。实验结果表明,商空间下的网络服务器跨层优化模型较传统网络服务器模型在性能上获得了显著提升,不仅传输延时方面降低了10%—15%,而且控制拥塞能力也上升了10%,对于处理网络服务器信息拥塞以及服务超载具有较好的指导和现实意义。
[Abstract]:The rapid development of network communication technology has not only brought about the progress of society, but also enriched people's daily life greatly. It brings severe challenges to traditional network servers, such as network information congestion and network service overload, which become important factors that affect the performance of network servers. In order to effectively solve the above problems and improve the performance of network server, this paper proposes a cross-layer optimization design of network server in quotient space, which focuses on the design optimization of network server from two aspects of structure and algorithm. The research work is mainly carried out from the following aspects: firstly, the background, significance and current research situation of network server performance research are expounded, and two major problems in network server performance optimization are pointed out. That is, the adaptability of network structure is not strong and the scheduling algorithm needs to be optimized, which is the starting point of this paper. Secondly, the quotient space theory and cross-layer technology involved in this paper are studied emphatically, and the characteristic advantages, common theories and implementation methods are summarized, and the performance problems of network server are analyzed. Based on the theory of quotient space, this paper presents a cross-layer server design and routing path planning algorithm from two aspects of architecture and algorithm optimization. Using OPNET Modeler as the network simulation platform, the server optimization model designed in this paper is simulated and modeled. An end-to-end communication network from the server to the user is designed for the cross-layer optimization model of the network server. The high-load environment of the server is simulated by configuring the network service and controlling the network parameters. The cross-layer optimization technology of network server in quotient space and its feasibility are verified. Finally, the experimental data are analyzed and summarized. The experimental results show that the performance of the cross-layer optimization model in quotient space is significantly improved than that of the traditional network server model. Not only the transmission delay is reduced by 10-15, but also the congestion control ability is increased by 10%, which has good guidance and practical significance for dealing with network server information congestion and service overload.
