Abstract

The dual server hot-standby mechanism is often used to improve the system availability. However, in traditional dual server hot-standby models, the states of servers are seldom determined from the client’s observation, and it’s easy for the master server and the slave server to make wrong decisions about the state of each other, which may cause split brain. This paper presents a multi-party decision hot-standby model. In this model, the master server and the slave server determine the state of each other not only from the observation of themselves, but also from the observation of the client, which helps them make correct decision to maintain or change the service platform, so as to ensure the continuity of application. Compared with traditional dual server hot-standby models, the model suggested in this paper is more reasonable because of the involvement of the client’s observation. DOI : http://dx.doi.org/10.11591/telkomnika.v12i4.4887
