摘　　要：根据海洋信息化发展的趋势和要求,原国家海洋局要求实现全面业务专网整合,打造海洋信息通信“一张网”。因此,国家海洋信息中心开展建设了以原国家海洋局机关、各分局、各业务单位为节点的主干网络,利用MPLS L3VPN技术,在网络中配置多个VPN,各个业务网从各个节点接入到主干网对应的VPN中,实现了“一个物理网,多个业务网”,不同业务之间可以彻底隔离、互不影响,同时满足不同节点间的不同业务间的互访,打破了信息壁垒,达到了整合网络资源、提高网络利用率、便于网络管理的目的。Driven by the development trend and requirements of marine informatization,the former State Oceanic Administration of China planned to realize the integration of comprehensive operational lines and build"one network"of marine information and communication.Therefore,the National Marine Data and Information Service has developed a backbone network with the bureau,sub-bureaus and operation units as nodes.Using MPLS L3 VPN technology,multiple VPNs are configured in the network,and each single network is connected to the corresponding VPN of the backbone network from each node,realizing"one physical network,multiple operations".Different services can be completely isolated from each other,not affecting each other,while meeting the needs of different services between different nodes.It breaks the information barrier,achieves the purpose of integrating network resources,and improves network utilization and facilitating network management.
