Network Transport Circuit Breakers Gorry Fairhurst University of Aberdeen (individual Submission)
Circuit breakers protect services A protection mechanism of last resort Reduce service starvation Prevent congestion collapse Not a congestion-control method
Functional Ntework Components Ingress meter Egress meter Measurement function Trigger function Reaction
trigger at different levels different response curves Fast-Trip Circuit Breaker Slow-trip Circuit Breaker Managed Circuit Breaker CBs come in different profiles
Next Steps Help to get a clearer understanding of the operational conditions under which circuit breakers should or must be deployed. Adopt in TSVWG?
