The Design And Implementation Of Enterprise Transmission Network Based On The RPR Technology

With the development of coal enterprise information, how to build a reliable, secure and efficient network platform to ensure the safety in production of enterprises to become the urgent needs of the coal industry. The current enterprise metropolitan area networking technologies such as SDH, Ethernet, etc. showing the following disadvantages:complexity of the technical, low quality of service, poor reliability, weak capacity of bandwidth management and so on. RPR technology combines the advantages of Ethernet and SDH technology, and has technical advantages of automatic discovery of network topology, loop bandwidth sharing, equitable distribution, fault self-healing, etc. The RPR technology provides a good solution to the data network building of coal enterprises.Building coal enterprise by RPR network technology was first raised in this paper. First, the author proceed from the coal company's network status, conditions of business development, research and analysis of the principle of RPR Technology; Summed up the three programs of building corporate networks by the RPR technology, Study and propose the most suitable program for coal enterprises; designed RPR transmission plus centralized routing of coal enterprises network, Multi-service deployment platform and an independent private network solution; take the case of enterprise network of Pingdingshan Coal Group (PCG), achieved a multi-service operation, bandwidth management,50ms Environmental Protection, independent dedicated network channels, a strong route network such as coal enterprises to build, meets the coal business requirements to business and functional of business network.Test verified this program was successfully used in enterprise networks of Pingdingshan Coal Group, and has strong compatibility and scalability, robust transmission capacity, routing capability and high reliability, provided an efficient, reliable, stable, secure network operating environment For enterprise information development, provide support for Coal business enterprise development and safe production.While, provides an excellent reference to precedents for the promotion and application of RPR technology.However, the author only studies one program of network construction programs by RPR in this paper, to more in-depth and thorough understanding of RPR, needed achieve research the other networking solutions. Believe that with the continuous advance of RPR standardization and continuous improvement of related products, RPR technology will be more widely used.
