If service providers choose a centralized collection, they have to size the collection link properly. Link sizing recommendation depends on :
- IWAN features enabled: More features = more data to export.
- Bandwidth per site repartition: headquarter with 500 employees will have more variety (=more export) than a small office with 20 employees)
- The time traffic distribution: the CPEs don’t have their max traffic at the same time.
A typical 10 000 CPE enterprise SP IWAN Network requires an 200 Mbps bandwidth
Collection link Max speed = Average flow size x Predicted Max aggregated traffic x Flow count at this max traffic
