Server redundancy technology solves the problem of availability and the performance bottleneck in the traditional distributed environment, and at the same time presents a new challenge to the system management. A kind of constituting principle and working model of a distributed database server system (DDSS) is presented in this paper. To overcome the weakness of dynamic scalability of redundancy resource in configuration management of the present redundancy server system, aiming at the server DDSS (every service in the system is abstracted to an object class in the model, and multi-instance of the same object class redundantly serving each other is proposed), the configuration management of redundancy resource is discussed, and adaptive configuration management policy based on mobile agent technology is proposed. With the precondition of ensuring the system availability, the system performance is improved and the resource waste is reduced. In ACM, by defining award-penalty function (as for static configuration) and user request arriving rate (as for dynamic configuration) which is the gist of configuration, redundancy instances is added or deleted dynamically. Finally, the algorithmic performance is analyzed and tested, and compared with traditional algorithm.

服务器冗余技术在解决传统分布式环境的可用性和性能瓶颈问题的同时,给系统的管理带来了新的挑战.介绍了一种分布式数据库服务器DDSS的构成原理及工作模型.为了解决当前冗余服务系统的配置管理中存在的冗余资源动态可扩展性不强的问题,针对服务器DDSS(模型把系统中的每种服务抽象成为一个对象类,并提出同一个服务对象类的多个实例互为冗余服务),对冗余资源的配置管理问题进行讨论,并提出基于移动代理技术的自适应配置管理ACM(adaptive configuration management)策略,在保证系统可用性的前提下提高系统的性能,减少资源浪费.在ACM中,通过定义奖惩函数(对于静态配置)和用户请求到达率(对于动态配置)来作为配置依据,对冗余实例进行动态增加或删除.最后,对算法的性能进行了分析、测试,并与传统算法进行了比较.

Lesson scheduling of universities is an important part of the academic affairs management. It is also a critical problem for routine work and rational arrangement of resources. While the data and constraints are few, a satisfied lesson schedule could be arranged manually. But with enlargement of school scale, this method cannot meet the present demand. So a lesson scheduling system is proposed which might be suitable to multi-campuses, little redundancy resource and many constraints. The system is based...

Lesson scheduling of universities is an important part of the academic affairs management. It is also a critical problem for routine work and rational arrangement of resources. While the data and constraints are few, a satisfied lesson schedule could be arranged manually. But with enlargement of school scale, this method cannot meet the present demand. So a lesson scheduling system is proposed which might be suitable to multi-campuses, little redundancy resource and many constraints. The system is based on a resource-requirement matrix algorithm with some improvement. It is better to solve the problem of lesson scheduling in university.

课程调度是高校教务管理的重要工作,是学校日常教学、资源合理使用的关键一环。当学校规模较小时,排课的数据量和约束条件较少,人工排课的方法尚可适用,但是随着学校规模的不断扩大,人工排课的效率和资源协调能力已经难以满足要求。文中借鉴一种需求资源矩阵的算法,对其进行了改进,并以此算法为核心,设计并实现了一个适合多校区、资源冗余较少、约束条件较多的课程调度系统,较好地解决了高校的课程调度问题。

Denial of Service(DoS) is a usual attack action in the Internet.This paper presents a scheme to prevent DoS attacks based on overlay networks.The system can provide services when it encounter a DoS attack by the redundancy resource and self-recover of the overlay network.

拒绝服务攻击(DoS)是Internet中常见的一种攻击形式,提出一种基于覆盖网络的防御DoS攻击的方案。通过覆盖网络中的冗余资源和自恢复功能确保系统在遭到DoS攻击时仍能提供一定性能的服务,并可自动从攻击中恢复正常。
