【摘要】 以安庆供电公司为例探讨如何建设一个信息广域网,骨干层采用环网结构,关键部位采用双交换机冗余设计,网络运行OSPF动态协议保证切换速度,有效地提高了网络可靠性,采用MPLS VPN协议,实现了同一通道内建立多条虚拟通道,将信息内、外网和县公司四级网数据相互隔离,利用MPLS隧道实现数据透明传输,借助标记自动为不同的VPN用户建立不同的虚通道,支持不同的安全等级,将每个VPN用户的数据隔离开来,有效地保证了信息内网数据安全。更多还原

【Abstract】 Taking Anqing Power Supply Company as an example,this paper discusses how to build an information WAN,with its backbone layer in annular structure and key positions in double exchange redundancy design.The network is operated on OSPF dynamic protocol suite,thus to ensure a high switch speed and improve the reliability of this network.By adopting MPLS VPN protocol suite,the realization of multiple virtual paths in the same channel is achieved,thus the data from the internal net,the external net and the county-level company is net could be mutually separated,and the data safety of internal net be effectively guaranteed.更多还原
