【摘要】：近年来互联网、移动互联网、物联网等业务发展迅猛,业务量激增,与上层业务密不可分的底层计算机通信网络的规模也呈现出迅猛增长的趋势。在这样的趋势下,网络管理技术也随之迅猛发展。我们课题组紧扣网络管理技术的发展方向,一直在从事网络管理技术的探索与系统实现工作,本课题就起源于此。本课题重点关注于网络管理中的信息呈现环节,通过在拓扑图上展示网络拓扑结构、被管对象状态、告警信息、性能信息,来达到一个信息的实时、生动、直观、层次清晰展示的效果。本论文的主要工作包括以下几个方面:(1)设计并实现Web网络拓扑展示系统基本功能。系统基本功能满足了网络管理信息呈现的各方面需要。(2)提出基于websocket技术的网络状况实时呈现方案。针对基础功能中实时呈现方面的不足,提出了以websocket代替Ajax轮询的设计方案,解决了 Ajax轮询实时性差、带宽浪费严重的问题。(3)设计了一套完善的拓扑历史信息存储方案。针对基本功能中历史回放方面的不足,设计了一套完善拓扑历史信息存储方案,降低了历史数据的冗余性。(4)以构建小地图的方式实现了鹰眼缩略图。针对基本功能中鹰眼缩略图的不足,通过构建小地图的方式实现了鹰眼缩略图,解决了谷歌地图鹰眼缩略图不能反映地图叠加层的问题。目前系统基础版本已经完全开发完成并上线使用。三个关键技术研究也都已经完成了解决方案的制定和功能实现。
[Abstract]:In recent years, the Internet of Internet, mobile Internet, Internet of things and other services have developed rapidly, and the volume of business has increased rapidly. The scale of the underlying computer communication network, which is closely related to the upper layer of business, has also shown a trend of rapid growth. In this trend, network management technology has also developed rapidly. Our research group has been engaged in the exploration and system realization of network management technology, which is the origin of this topic. This subject focuses on the information presentation in network management. By displaying network topology, managed object state, alarm information and performance information on topology diagram, we can achieve a real-time, vivid and intuitive information. The level clearly shows the effect. The main work of this paper includes the following aspects: 1) designing and implementing the basic functions of the Web network topology display system. The basic functions of the system meet the needs of all aspects of network management information presentation. (2) A real-time network status presentation scheme based on websocket technology is proposed. Aiming at the deficiency of real-time presentation in basic function, a design scheme of replacing Ajax polling with websocket is proposed, which solves the problem of poor real-time performance of Ajax polling and serious waste of bandwidth. A set of perfect storage scheme of topology history information is designed. Aiming at the deficiency of historical playback in basic function, a set of perfect storage scheme of topological history information is designed, which reduces the redundancy of historical data. (4) Eagle eye thumbnail is realized by constructing small map. Aiming at the shortage of Hawkeye thumbnail in the basic function, this paper realizes the Eagle Eye thumbnail by constructing a small map, and solves the problem that Google Maps Hawkeye thumbnail can not reflect the map superposition layer. At present, the basic version of the system has been fully developed and used online. Three key technologies have also been completed in the formulation and functional implementation of the solution.
