Network Architecture and Optimization of Cloud Data Center for Heavy-Haul Railway
A communication network for a dedicated cloud data center was built for heavy-haul railway based on a data center.In response to the characteristics of the heavy-duty railway business system,this paper utilized SDN software to define the network method.It virtualized the resources of physical network devices into reusable and freely allocated virtual network resources,achieving the virtualization of network resources and resource pool management.The paper flexibly allocated and adjusted network resources according to business configuration needs.It used the Spine-Leaf framework,link redundancy,load balancing products combined with path optimization,and other network optimization technologies to achieve a high-security,high-reliability,scalable,and full-process basic network environment.The network environment supports the rapid development and iteration of new railway business applications,achieving infrastructure co-construction and sharing,data resource aggregation and sharing,and agile deployment of business systems for railway logistics business.It comprehensively improves the level of railway logistics informatization and provides a basic support network for Intelligent Railway and Smart Logistics.
