daemon-reload A definition of High Availability Clusters from Wikipedia: High Availability Clusters High-availability clusters (also known as HA clusters , fail-over clusters or Metroclusters Ac- tive/Active ) given a target and fence device parameters. • crmsh - Advanced command-line interface for High-Availability cluster management in GNU/Linux. • pcs - Pacemaker command line interface and GUI. It permits devices. • Keepalived - Keepalived provides simple and robust facilities for loadbalancing and high-availability to Linux system and Linux based infrastructures. Loadbalancing framework relies on well-known

Communications United Architecture (OPC UA) protocol • Time-Sensitive Networking (TSN) protocol • High-availability Seamless Redundancy (HSR)/Parallel Redundancy Protocol (PRP) • Network Configuration Protocol
