【摘要】：近年来,网络负载的持续增加引起了研究人员对于如何提高资源利用率的思考。同时,随着网络的发展,网络架构和网络协议的种类越来越多。但是,目前网络架构在灵活性和隔离性上存在不足,严重阻碍了网络的创新和发展。网络虚拟化技术允许在共享底层物理网络的基础上构建彼此隔离的虚拟网络,从而解决传统网络架构灵活性、隔离性差的问题。网络虚拟化技术的发展衍生出一系列网络虚拟化实验平台,这些实验平台为新技术、架构提供验证平台。然而,针对任何一个网络虚拟化环境,都需要对其进行管理和维护。而且随着网络规模的增大和网络结构的复杂,网络虚拟化环境下资源调度的难度也越来越大。本文要设计实现的网络虚拟化管理平台资源调度模块,为网络虚拟化环境提供资源管理服务,同时也可以对资源调度算法、调度策略等网络虚拟化环境下资源调度关键技术进行验证,对网络虚拟化环境的运营和管理进行有益的探索。本文首先从网络虚拟化环境入手,分析网络虚拟化技术给网络商业模型和架构带来的新特点。而后进一步分析了网络虚拟化环境下的资源调度问题,使用数学抽象的方法对其进行描述,抽象出资源调度模块所要解决的原型问题,为后续设计实现奠定基础。接下来,对资源调度模块进行需求分析,从资源调度问题涉及的两类资源和一类关系三个方面出发,分析出具体的资源管理需求和映射关系管理需求。用于指导后续数据库表、类及主要函数的设计。然后,从资源调度模块设计实现的三个主要业务场景出发进行详细的功能需求分析。在需求分析后,对资源调度模块的数据库进行详细设计。而后对三个典型业务场景中的算法进行详细介绍,并对模块涉及的重要类进行设计。最后在以上分析、设计的基础上对模块进行功能实现与测试。
[Abstract]:In recent years, the continuous increase of network load has caused researchers to think about how to improve resource utilization. At the same time, with the development of network, there are more and more kinds of network architecture and network protocols. However, the lack of flexibility and isolation in the current network architecture seriously hinders the innovation and development of the network. Network virtualization technology allows the construction of isolated virtual networks based on shared underlying physical networks, thus solving the problem of traditional network architecture flexibility and poor isolation. The development of network virtualization technology gives rise to a series of network virtualization experimental platforms, which provide verification platform for new technologies and architectures. However, any network virtualization environment needs to be managed and maintained. With the increase of network scale and the complexity of network structure, resource scheduling is becoming more and more difficult in network virtualization environment. In this paper, the resource scheduling module of network virtualization management platform is designed to provide resource management services for network virtualization environment. The key technologies of resource scheduling in network virtualization environment, such as scheduling strategy, are verified, and the operation and management of network virtualization environment are explored. This paper begins with the network virtualization environment and analyzes the new characteristics of network virtualization technology to the network business model and architecture. Then the resource scheduling problem in network virtualization environment is further analyzed and described by mathematical abstract method. The prototype problem to be solved by resource scheduling module is abstracted to lay the foundation for subsequent design and implementation. Then, the requirements of resource scheduling module are analyzed, and the specific resource management requirements and mapping relation management requirements are analyzed from the three aspects of two kinds of resources and one kind of relationship involved in the resource scheduling problem. Used to guide the design of subsequent database tables, classes and main functions. Then, the detailed functional requirements analysis is carried out from the three main business scenarios designed and implemented in the resource scheduling module. After requirement analysis, the database of resource scheduling module is designed in detail. Then the algorithms in three typical business scenarios are introduced in detail, and the important classes involved in the module are designed. Finally, on the basis of above analysis and design, the module is implemented and tested.
