Redundancy
Redundancy refers to the resiliency of communications systems that is achieved by alternative means or systems. Redundancy provides for multiple interchangeable components that can perform a common function as well as backup systems that perform a common function in the event of failure, mishap, or change in operational conditions. Redundancy is the provisioning of duplicative or repetitive components or systems to perform a common function. Redundancy of systems is a method of insurance against failure of primary system functionality. Redundancy may also be used in an a priori manner to preclude errors or failures from occurring in order to insure error free exchange of information.
