    摘要: A system and method for supporting network mobility based on identifier-locator separation, provides seamless session services to terminals inside the mobile network by enabling a variety of tunnel routers (home tunnel router, visit tunnel router, etc.) on network to store/manage mobile network mapping information for network mobility. The system for supporting network mobility based on identifier-locator separation includes: a mobile router configured to register mobile network identification information in a home tunnel router, and support communication with the home tunnel router, on behalf of mobile network nodes located in a home network; and a home tunnel router configured to support communication with a correspondent node by using tunnel router mapping information, and support communication with the mobile router by using mobile network mapping information.

    摘要: Highly pure simvastatin can be prepared economically in a high yield using the method comprising the steps of treating lovastatin with potassium hydroxide dissolved in a mixture of water and methanol to obtain a triol acid; relactonizing the triol acid, and protecting the hydroxy group on the lactone ring; and acylating the resulting compound with 2,2-dimethylbutyryl chloride or 2,2-dimethylbutyryl bromide in the presence of an acylation catalyst in an organic solvent, followed by removing the silyl protecting group on the lactone ring to obtain simvastatin.
