Bandwidth Optimization Of Education Man Based On Caching Technology

Education is the foundation of the country,the great power must be strong first in education.All the time,the development of education is a work of particular attention over the world,With the continuous popularization of the Internet,education has been more and more inseparable from the informatization technology,the informatization level of education is also developing.The Internet is the basic carrier of education informatization,and the demand for Internet applications is increasing.Network bandwidth resources are becoming more and more intense.According to the statistics,the Internet bandwidth demand increased by nearly four times from 2010 to 2015.In the near future,the optical fiber bandwidth will reach the limit of design capacity.Therefore,the optimization of network outlet bandwidth has attracted more and more attention.Network caching is a temporary storage of network data that needs to be temporarily stored in a specific server.Through the monitoring and analysis for the users' network requests,and by forwarding the network requests to the designated internal network server,we can get the network resources needed through the local network.By researching the current technology and combining the characteristics of educational informatization,the design requirement has been identified for the bandwidth optimization of this education MAN,and the technical scheme is formulated.The optimization scheme is based on network caching technology,using distributed design concept,using Squid to implement the network caching system platform and form caching regional coopration.Starting from the operation of the current education MAN,the demand analysis and technical investigation are completed in turn.On the basis of the full experiment,the school level,district and county level caching system are completed.Finally,the system test is passed,and the system is running.During the development of the system,I participated in the preliminary work of the overall situation investigation and the requirements analysis,and independently completed the guidance work of the cache system at all levels.After the system is running,it effectively relieves the pressure on the Internet bandwith of the education MAN,significantly improves the response time of the network access,and further improves the working efficiency driven by the educational informazitation.The latest informazitation technology is applied to the field of education,which provides a new way for finding suitable technology for education.
