| Hans-G?nter@22983 | 1 The main goal of this project is to provide simple and robust facilities |
| Hans-G?nter@22983 | 2 for loadbalancing and high-availability to Linux system and Linux based |
| Hans-G?nter@22983 | 3 infrastructures. Loadbalancing framework relies on well-known and widely |
| Hans-G?nter@22983 | 4 used Linux Virtual Server (IPVS) kernel module providing Layer4 loadbalancing. |
| Hans-G?nter@22983 | 5 Keepalived implements a set of checkers to dynamically and adaptively maintain |
| Hans-G?nter@22983 | 6 and manage loadbalanced server pool according their health. On the other hand |
| Hans-G?nter@22983 | 7 high-availability is achieved by VRRP protocol. VRRP is a fundamental brick for |
| Hans-G?nter@22983 | 8 router failover. In addition, Keepalived implements a set of hooks to the VRRP |
| Hans-G?nter@22983 | 9 finite state machine providing low-level and high-speed protocol interactions. |
| Hans-G?nter@22983 | 10 In order to offer fastest network failure detection, Keepalived implements BFD |
| Hans-G?nter@22983 | 11 protocol. VRRP state transition can take into account BFD hint to drive fast |
| Hans-G?nter@22983 | 12 state transition. Keepalived frameworks can be used independently or all |
| Hans-G?nter@22983 | 13 together to provide resilient infrastructures. |
| Hans-G?nter@22983 | 14 |
| Hans-G?nter@22983 | 15 Keepalived implementation is based on an I/O multiplexer to handle a |
| Hans-G?nter@22983 | 16 strong multi-threading framework. All the events process use this I/O |
| Hans-G?nter@22983 | 17 multiplexer. |
