Abstract: The present invention discloses a method and device for processing data caching, wherein the method includes: storing cached data into a memory; after reading out the cached data from a memory space address for storing the cached data in the memory, judging whether the cached data that have been read out are the same as the cached data to be written before the storing, if so, then deciding that the memory space for storing the cached data in the memory is normal; if not, then deciding that the memory space for storing the cached data in the memory is abnormal; and when the cached data is stored during the subsequent data caching process, storing the cached data only into the memory spaces in normal state in the memory. The present invention can be implemented with simple code migration and may be directly applied to an existing device for data caching to detect whether an unsafe memory space exists in the memory, thus improving the reliability of data caching.

Abstract: The present invention discloses a device and method for implementing a transparent clock. The device comprises: a clock module, a data identification module and a data correction module, wherein the clock module is connected with the data identification module and the data correction module respectively, and used for providing clock information to the data identification module and the data correction module; the data identification module is used for receiving data and acquiring current time information from the clock module; and the data correction module is connected with the data identification module, and is used for accumulating a positive or negative value of the current time information with the time information included in the data according to an outputting direction of the data and outputting the accumulated time information together with the data. By adopting the present invention, the residence time information of the data in the switching node is acquired by a hardware device, and the time information included in the data is corrected according to the residence time information, so that the transparent clock of the data can be effectively implemented, and the acquired residence time information is of a high precision and is acquired stably.
