Impact of QoS LSAs
Trade-off between accuracy of network state information and LSA load
- High LSA load ? Accurate network information
Frequency of LSAs (updates) depends on
- How updates are triggered
- Class based triggers
- Threshold triggers
- Existence and settings of hold-down timers
- What values are advertised (actual or coarse)
Questions
- Relation between LSA load and state accuracy
- Impact of inaccuracy on routing performance
