CISCO-SEU-MITIGATION-MIB

This MIB reports the status of non-automatic and automatic,
        rate-adaptive Single Event Upset (SEU) mitigation algorithms and
        adjusts their parameters, as well as reports the effects of 
        those mitigations on memories, caches, and registers. SEU 
        mitigation allows Cisco IOS to run on radiation tolerant 
        hardware deployed in a geosynchronous Earth orbit satellites for
        IP communications. One of the challenges in deploying equipment 
        in such an environment is the impact that radiation has on 
        digital circuits. A Single Event Upset (SEU) occurs when the 
        hardware is exposed to energetic ions and protons in the space
        environment. The value stored in a bit of information can change
        when a large enough charge is deposited on the digital circuit. 
        This leads to adverse effects in the operation of the software;
        in this case Cisco IOS. While steps have been taken to reduce 
        the occurrence of SEUs through the use of radiation tolerant 
        hardware, these steps do not eliminate the threat. A critical
        requirement in running IOS on such platforms is the utilization
        of SEU mitigation strategies to reduce the impact of such events
        on the operation of the Cisco device.
        
                 GLOSSARY
        
        SEU  :   Acronym for 'Single Event Upset' : A hardware 
                 disruption caused when hardware is exposed to energetic
                 ions and protons.
        
        scrub :  An algorithm that periodically refreshes memory, cache
                 or register contents by various means.
