Research on Information Communication Carrier Network Frame of the Directly Affiliated Units of Energy Firms

摘要

At present, the information communication network of the directly affiliated units of energy firms has many problems, such as diverse access mode, weak operation and maintenance strength, and insufficient network bandwidth, leading to the consequences that the network construction standard is differentiated, the network operation management is backward, the cost of link is high, and the ability of communication resource sharing is poor, which has been unable to meet the requirements of the rapid development during the 12th Five-Year-Plan period. After analyzing the bandwidth demand, the total bandwidth demand of Henan province worked out to 1.7G. Then, the network architecture was studied on the principle of uniformity, economy, standard, security, compatibility and expandability. Finally, this paper proposed the measures of multi-level defense and horizontal isolation for security control to effectively guarantee the safe and stable aeration of the information communication carrier network of the directly affiliated units of energy firms.
