How can I size the centralized collection link ?

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
