摘要
网上评卷系统采用J2EE架构,Web页面以图片为主,页面显示要求流畅连续,没有明显延迟,评卷期间不能因设备故障影响评卷进度,对服务器的性能和硬件设备的可靠性要求较高。本文着重从基础硬件架构角度对网上评卷系统进行重新设计和优化,实现统一的、通用的网上评卷架构,能满足系统高负荷下的高性能和高可靠性要求。
Online marking system using J2 EE architecture,Web pages mainly with pictures.Pages displayed requirements smooth and continuous,no significant delays.During the marking is not due to equipment failure affecting marking progress,it requirements high performance for server and high reliability for hardware.This article focuses on the redesign and optimization of online marking system from the perspective of underlying hardware architecture,to implement a unified,universal online marking architecture.It can meet performance and reliability requirements of the system under high load.
