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。
Anqing Power Supply Company as an example to explore how to build an information WAN, the backbone layer using ring network structure, the key parts of the dual redundant switch design, the network running OSPF dynamic protocol to ensure the switching speed, effectively improve the network reliability, MPLS VPN protocol , To achieve the establishment of a number of virtual channels within the same channel, the information inside and outside the network and county company four network data from each other, the use of MPLS tunnel data transparent transmission, with the help of different VPN users automatically create different virtual channels, Support different levels of security, each VPN user’s data isolation, effectively ensure the safety of information intranet data.
