Abstract: AAA server supporting radius protocol is widely applied in telecommunication industry. In this paper, a memory cache technology is introduced, which can promote AAA server's performance with 2~3 order of magnitude.With Unix system V shared memory technology, semaphore synchronizing competitively occupies resources among multiple processes, hash table implements fast search in massive data.
