The term "failover", although probably in use by engineers much earlier, can be found in a 1962 declassified NASA report. [2] The term "switchover" can be found in the 1950s [3] when describing '"Hot" and "Cold" Standby Systems', with the current meaning of immediate switchover to a running system (hot) and delayed switchover to a system that needs starting (cold).
Version 1 of the protocol was described in RFC 2281 in 1998. Version 2 of the protocol includes improvements and supports IPv6 but there is no corresponding RFC published for this version. The protocol establishes an association between gateways in order to achieve default gateway failover if the primary gateway becomes inaccessible.
SMLT provides enhanced resiliency with sub-second failover and sub-second recovery for all speed trunks while operating transparently to end-devices. Multi-chassis link aggregation group provides similar features in a vendor-nonspecific manner. To the connected device, the connection appears as a normal link aggregated trunk.

High-availability Seamless Redundancy (HSR) is a network protocol for Ethernet that provides seamless failover against failure of any single network component. PRP and HSR are independent of the application-protocol and can be used by most Industrial Ethernet protocols in the IEC 61784 suite. HSR does not cover the failure of end nodes, but ...

Meanwhile, the S&P 500's current high valuation, which sits at a 21.5 forward 12-month price-to-earnings ratio, per FactSet, is well above the five-year average of 19.7 and the 10-year average of ...
Switchover is the manual switch from one system to a redundant or standby computer server, system, or network upon the failure or abnormal termination of the previously active server, system, or network, or to perform system maintenance, such as installing patches, and upgrading software or hardware.
