Method and system to simulate delays in geographically distributed computing environments

摘要

Systems and methods are described for implementing a delay driver within a cluster service storage stack, which delay driver simulates the latency experienced between two nodes in geographically distant locations. The delay driver determines whether I/O request packets should be delayed, selects the number and types of I/O requests packets to be delayed and the amount of time to delay processing of the packets. Through the use of such a driver, a user is able to simulate various conditions that geoclusters may experience when separated over large distances.
