SLA Metrics: Throughput
Throughput characterises the available user bandwidth between an ingress POP and egress POP
Defined in two ways:
“pipe” model: point-to-point
“hose” model: point-to-multipoint [ref: DUFFIELD]
Does not define goodput
Goodput (i.e. useful TCP throughput) is dependent upon many factors including: round-trip delay, loss rate, TCP implementation, RED/Tail-Drop implementation … [ref: MATHIS]
