Objective<br />
• SLA enforcement<br />
• expressed as loss, latency and jitter availability targets<br />
• How is SLA monitored<br />
• PoP to PoP active probes<br />
• Per-link or per-class drops<br />
• How to enforce<br />
• Ensure that capacity exceeds demands frequently enough to<br />
achieve availability targets<br />
• Highlight: catastrophic events (multiple non-SRLG failures) may lead<br />
to “planned” congestion. The planner decided not to plan enough<br />
capacity for this event as the cost of such a solution outweights the<br />
penality. A notion of probability and risk assessment is fundamental to<br />
efficient capacity planning.<br />
