日前,Olivetti公司作为中标的系统集成商。选用Cisco网络产品为中国石油天然气管道勘察设计院建成了全交换式网络系统工程,并顺利通过验收。石油天然气管道设计院是中国石油天然气总公司下属的甲级设计院。近年来,设计院计算机绘图量大幅度上升,各专业之间资料互用日益频繁,各项管理所需的数据量也迅速增加。该院新建具有开放性的全交换式网络系统,集中运用了当今网络系统的三大热门技术,即交换技术、虚拟技术和网络管理技术,不仅符合国际规范和标准、满足了现时工作的需要,并且具有很强的系统升级能力。该网络通信系统以设计院网络中心为核心,采用Cisco的网络交换机进行楼层的星形拓扑结构连接,形成两级交换的点到点全交换系统,满足了设计院在网络上要有大量图像数据传送的需 A few days ago, Olivetti company as the successful system integrator. The use of Cisco network products has established a fully-switched network system project for the China National Petroleum Pipeline Survey and Design Institute, and has successfully passed acceptance. The Oil and Gas Pipeline Design Institute is a Class A design institute under the China National Petroleum Corporation. In recent years, the amount of computer graphics in design institutes has risen dramatically. The interoperability of data between professionals has become increasingly frequent, and the amount of data required for management has also rapidly increased. The hospital has built an open and fully exchanged network system, and has concentrated on the three hot technologies of today’s network systems, namely, switching technology, virtual technology, and network management technology. It not only meets international norms and standards, but also meets the needs of current work. And have a strong system upgrade capabilities. The network communication system is centered on the design institute network center and uses Cisco’s network switches to connect the star topology of the floors to form a two-stage exchange point-to-point full-exchange system, which satisfies the design institute’s need for a large amount of image data on the network.
