Construction of private network acceleration system for coal enterprise

For problems of private network of coal enterprise such as poor network quality, regional limitation, lack of reasonable scheduling of bandwidth resources, inability of enterprise cloud platform to remote backup and poor network security, a construction scheme of private network acceleration system for coal enterprise was proposed. Local access acceleration is realized through deploying Internet caching system by mirroring mode. Long-distance wavelength division transmission platform is established by using wavelength division multiplexing technology, so as to realize remote backup of enterprise cloud platform and guarantee network security. The long-distance wavelength division transmission platform is connected to Internet exchange center, which can speed up access of Internet users to mainstream websites in China. Domain name list of the domestic mainstream websites is configured by employing intelligent DNS scheduling system, so as to reasonably schedule Internet export bandwidth resources. The application results verify effectiveness of the private network acceleration system for coal enterprise.
