Summary:High reliability is one of the main challenges that the Ethernet technology achieves the request of telecom standard. This paper introduces two Ethernet protection mechanisms: MSP and UPSR which are commonly used by the MSTP network, and points out the limitations of the two protection mechanisms, combined with the advantages of the two protection mechanisms, we advance a new method that across use MSP and UPSR protection in SDH ring network which were composed by MSTP. In the testing of 2.5G MSTP network equipment, it proves that the method is better than a single protection in the protection switching and restoration effective.
