Round-robin DNS is a technique of load distribution, load balancing, or fault-tolerance provisioning multiple, redundant Internet Protocol service hosts, e.g., Web server, FTP servers, by managing the Domain Name System's (DNS) responses to address requests from client computers according to an appropriate statistical model.
There is a difference between fault tolerance and systems that rarely have problems. For instance, the Western Electric crossbar systems had failure rates of two hours per forty years, and therefore were highly fault resistant. But when a fault did occur they still stopped operating completely, and therefore were not fault tolerant.
A virtual IP address (VIP or VIPA) is an IP address that does not correspond to a physical network interface. Uses for VIPs include network address translation (especially, one-to-many NAT ), fault-tolerance, and mobility .
Alternatively, a single hostname may resolve to many IP addresses to facilitate fault tolerance and load distribution to multiple server instances across an enterprise or the global Internet. DNS serves other purposes in addition to translating names to IP addresses.
Stratus Technologies, Inc. is a major producer of fault tolerant computer servers and software. The company was founded in 1980 as Stratus Computer, Inc. in Natick, Massachusetts, and adopted its present name in 1999. The current CEO and president is Dave Laurello.
The preceding intuitive discussion implies simple technique for implementing a fault-tolerant service in terms of a State Machine: Place copies of the State Machine on multiple, independent servers. Receive client requests, interpreted as Inputs to the State Machine. Choose an ordering for the Inputs. Execute Inputs in the chosen order on each ...
A fault-tolerant computer system can be achieved at the internal component level, at the system level (multiple machines), or site level (replication).. One would normally deploy a load balancer to ensure high availability for a server cluster at the system level. [3]
Fault Tolerant Ethernet (FTE) is proprietary protocol created by Honeywell. [1] [2]Designed to provide rapid network redundancy, on top of spanning tree protocol. [3] Each node is connected twice to a single LAN through the dual network interface controllers.
