Loadbalancing framework relies on well-known and widely 1.7 +used Linux Virtual Server (IPVS) kernel module providing Layer4 loadbalancing. 1.8 +Keepalived implements a set of checkers to dynamically and adaptively maintain 1.9 +and manage loadbalanced server pool according their health. On the other hand 1.10 +high-availability is achieved by VRRP protocol. VRRP is a fundamental brick for 1.11 +router failover. In addition, Keepalived implements a set of hooks to the VRRP 1.12 +finite state machine providing low-level and high-speed protocol interactions. 1.13 +In order to offer fastest network failure detection, Keepalived implements BFD 1.14 +protocol. VRRP state transition can take into account BFD hint to drive fast 1.15 +state transition. Keepalived frameworks can be used independently or all 1.16 +together to provide resilient infrastructures. 1.17 + 1.18 +Keepalived implementation is based on an I/O multiplexer to handle a 1.19 +strong multi-threading framework. All the events process use this I/O 1.20 +multiplexer.
