Abstract
Page replacement algorithm is an important content in memory management of the operating system. In order to study the difference and relation between different page replacement algorithms,and the impact they have on system thrashing, the different replacement algorithms are compared,and the principles and ideas of several common page replacement algorithms are elaborated. Through the thrashing analysis experiments,three ways to solve the system thrashing were achieved by improving the page replacement algorithm. The system thrashing can be effectively controlled by local page replacement algorithm to dynam-ically adjust page replacement algorithm and track the page missing rate.关键词
