发布时间：2019-05-18 18:10
【摘要】：随着互联网的逐步发展,网络人才的培养对环境的需求越来越高,越来越需要一个能够给科研人员提供快速配置设备,灵活构建网络的计算机网络实验平台。但是随着新技术和新设备的不断出现,实验平台网络的复杂性在不断的增加,系统的异构性变得越来越普遍,其采用的网络设备种类繁多、类型各异,配置命令不尽相同,并且往往需要为多个不同的实验场景分别构建相似的网络环境。按照通常的网络设备配置流程,需要管理人员手工进行配置,由于实验平台中的设备存在分布式部署的情况,加上设备特性和管控协议的不统一,这种方式不仅效率低下,而且容易出现人为失误。在管理和配置上相当不灵活自主,不利于进行创新性网络技术研究,也相对制约了网络实验平台的发展。为了促进创新性网络技术研究和测试以及实验平台的发展,研究一种统一的网络设备配置技术对于网络管理技术的发展具有重要意义,也是当前网络实验平台的发展趋势。这种配置技术应该能够根据用户的特定需求,灵活的配置管理已有的网络资源,完成实验环境的快速搭建。本课题针对传统网络环境中交换设备控制平面和数据转发平面紧耦合的缺点,将控制平面和数据平面进行解耦,在控制平面针对不同设备的特点选取适合的配置技术实现对网络中资源的配置管理,实现配置方式对管理人员的透明,以一种类似于SDN方式对实验平台的设备进行配置管理。本课题在对现有的配置管理方式的研究基础之上,通过将网络拓扑中信息抽象为数据库表项,并通过这些表项映射实验平台中设备的各种属性,完成网络信息的数据建模。针对不同类型的设备,通过对相应技术进行整合和开发,在通用数据模型的基础上开发不同的配置组件,实现对支持Netconf协议设备、OpenFlow设备、虚拟化设备和使用传统命令行方式进行管理的设备的配置管理支持。即满足了对新技术、新设备的探索,也对适用范围最广的传统物理设备的配置方式进行了深化。其中CLI组件提供了一种基于模板的配置方式,使得系统具有较好的扩展性。同时,系统还提供上层接口,实现与实验平台其他管控系统间的结合,共同推动和完成实验平台设备自动化部署的目标。
[Abstract]:With the gradual development of the Internet, the training of network talents has a higher and higher demand for the environment, and more needs a computer network experimental platform which can provide researchers with rapid configuration equipment and flexibly construct the network. However, with the continuous emergence of new technologies and new equipment, the complexity of the experimental platform network is increasing, and the heterogeneity of the system becomes more and more common. There are many kinds of network devices used, different types, and different configuration commands. And often need to build a similar network environment for multiple different experimental scenarios. According to the usual network equipment configuration process, managers need to configure it manually. Because of the distributed deployment of the devices in the experimental platform, coupled with the inconsistency of device characteristics and control protocols, this approach is not only inefficient. And prone to human error. It is not flexible and autonomous in management and configuration, which is not conducive to the research of innovative network technology, and also restricts the development of network experiment platform. In order to promote the research and test of innovative network technology and the development of experimental platform, it is of great significance to study a unified network equipment configuration technology for the development of network management technology, and it is also the development trend of network experimental platform at present. This configuration technology should be able to flexibly configure and manage the existing network resources according to the specific needs of users, and complete the rapid construction of the experimental environment. In order to solve the problem of tight coupling between the control plane and the data forwarding plane of the switching equipment in the traditional network environment, the control plane and the data plane are decoupling. In the control plane, the suitable configuration technology is selected according to the characteristics of different devices to realize the configuration management of the resources in the network, to realize the transparency of the configuration mode to the managers, and to configure the equipment of the experimental platform in a way similar to SDN. Based on the research of the existing configuration management methods, this paper abstracts the information in the network topology into database table items, and maps the various attributes of the equipment in the experimental platform through these table items to complete the data modeling of the network information. According to different types of equipment, through the integration and development of the corresponding technology, different configuration components are developed on the basis of the general data model, and the supporting Netconf protocol devices and OpenFlow devices are realized. Configuration management support for virtualized devices and devices managed using the traditional command-line approach. That is to say, it satisfies the exploration of new technology and new equipment, and also deepens the configuration mode of traditional physical equipment, which is the most widely applicable. Among them, CLI component provides a template-based configuration method, which makes the system have good scalability. At the same time, the system also provides the upper interface to realize the combination with other control and control systems of the experimental platform, and jointly promotes and completes the goal of automatic deployment of the experimental platform equipment.
