Research Of Mechanism Metro Ethernet Multiple Services Ring

With the rapid development of Internet, e-mail and browsing the web on the Internet is not the sole purpose of people, but to spend a minimum cost to get more services of broadband. Virtual Private Network, distance education, telemedicine and other businesses in the ascendant, application requirements of broadband MAN can meet multi-service carried out at the same time.Multiple Services Ring is proposed by Wuhan Research Institute of Posts and telecommunications, with the international advanced level of metropolitan optical networking and application of international standards, It can achieve integration transmission and exchange, thereby promoting the integration of multi-service, MSR creatively put forward the concept of branch operations, you can achieve the perfect combination of business transfer and exchange.and it was adopted by ITU-T. The key technology is a tributary service business protection.This article first give a Comprehensive research and analysis on the MSR standard,and proposed the implementation scheme. It discussed in detail in two modes, two management two monitoring, that running business in the ring can provide unicast, multicast, and broadcast mode.This article creatively propose a fault detection and switching consultation mechanism base on branch operations, This paper designs the realization and simulation MSR network link based switching time, and under different network structures of MSR over RPR switchover time is compared with several other time Ethernet ring protection, business protection proved MSR advantage of. Papers also standard on the basis of multi-service MAN ring network model and system design, the paper work for the development of technology and the popularity of MSR has laid a good foundation, with great theoretical significance and practical value.
