A common solution to the high availability problem is to eliminate the security gateway as single point of failure by introducing redundancy. With two or more redundant security gateways, if one fails, the remaining one or more gateways keep the traffic flowing. FortiOS provides six redundancy solutions: industry standard VRRP as well as five proprietary solutions: FortiGate Cluster Protocol (FGCP) high availability, FortiGate Session Life Support Protocol (FGSP) high availability, Session-Aware Load Balancing Clustering (SLBC), Enhanced Load Balanced Clustering (ELBC) and Content Clustering.
