随着企业信息化建设的不断推进,信息技术的应用对业务的支撑和引领作用日益凸显。基础网络架构的设计需适应业务板块快速发展和业务系统的架构模型,需满足网络安全互访、专业应用安全访问的需求。MPLS VPN网络在电信行业中已得到了广泛应用,但在能源行业企业骨干网运用MPLS VPN技术尚数首例,创造性的实现逻辑隔离基础上的跨VPN交叉互访,组网技术居同行业领先水平。1前言企业快速发展,业务单位对信息系统的依赖性日渐增高,
With the continuous promotion of enterprise information construction, the support and leading role of information technology application to the business has become increasingly prominent. The design of the basic network architecture needs to adapt to the rapid development of the service sector and the architecture model of the service system. The basic network architecture needs to meet the requirements of network security exchange visits and professional application security access. The MPLS VPN network has been widely used in the telecom industry. However, the first case of using MPLS VPN technology in the backbone network of the energy industry is still creative. It implements cross-VPN cross-exchange based on logical isolation, and the networking technology occupies the leading position in the industry Level. 1 Preface The rapid development of enterprises, business units increasingly dependent on the information system,
