Design And Implementation Of Enterprise Network Based On OTN Technology

Optical Transport Network(OTN)is a transmission network that organizes networks in the optical layer based on wavelength division multiplexing technology and is the next generation backbone transmission network.Starting from the goal of establishing and perfecting the oilfield backbone network,this paper understands the development status of OTN at home and abroad by consulting the data,is familiar with the key technologies of OTN,conducts on-the-spot investigation on the current situation and demand of the oilfield backbone network,and finds that the oilfield backbone network has the following problems and deficiencies: First,the network Low security,lack of means for network logic isolation and management by business segment;second,lack of traffic analysis,bandwidth guarantee and management tools based on business applications;third,existing bandwidth is difficult to meet critical business needs.Through the analysis of the characteristics and current situation of the oilfield network,the design research of the oilfield backbone network transmission network,digital communication network,network monitoring and management platform is proposed.The main research contents are as follows:(1)Using OTN technology to study the transmission ring network,according to the transmission The design idea of looping,digital communication,and three-dimensional layering realizes high-speed and high-reliability high-speed transmission layer ring network;(2)researching digital network network architecture optimization and network security isolation to realize digital communication network interconnection Adopt network virtualization technology to achieve safe isolation between production units and other sector units;(3)Improve network monitoring and management capabilities,strengthen network security management and control capabilities,achieve key application key guarantees,traffic scheduling automation,and network traffic visualization.The research results of this paper have created good environmental conditions for“digital oilfield construction”,which has helped the high-quality development of oilfield enterprises and effectively enhanced the core competitiveness of enterprises.The research results are mainly reflected in:(1)Applying OTN technology to solve the problem of network congestion in oilfield enterprises,achieving network performance improvement and effectively improving business support capabilities.(2)Developed a traffic visualization platform to achieve priority protection for key businesses and improved the level of refined management of enterprise networks.(3)Established a new network security management system for oilfield enterprises,realized barrier isolation and improved network security protection capabilities.
