摘要

Since emerged in 2004, Unified Threat Management (UTM) has been brought into wide use to enhance network security protection. In practical use, UTM can not only be treated as gateway to control the connection of inner net and outer net, but also as safety devices providing many services and functions including access control, intrusion prevention , anti-virus and so on. Therefore, the much higher request is bring up for the high-availability of UTM. To address this issue, this paper presents UTM-HA (UTM High Availability), a solution to improve the high-availability of UTM. The solution has been implemented and its performance was evaluated.
