Background:

In Kohn Version, we focus on the implemetation of  provision intent and assurance intent. 

Provision intent: Create a cloud leased line A (CLL).

Assurance intent: Add / Remove bandwidth adjustment assurance for clound leased line A.







What does an assurance intent do?

Let's say, Company A ordered a cloud leased line (CLL) , it's a 1G cloud leased line between point A and point B.

However, the bandwidth usage of this cll usually burst around 30% from 7pm to 8 pm everyday. In other time during the day, the bandwidth usage is normal.

So we provide users another choice, that they can order an extra service for CLL. 

If the real time bandwidth usage exceeds the bandwidth they ordered, then we increase the maximum bandwidth allocated to this cll temporally. When the real time bandwidth usage decrease to normal, then we decrease the maximum bandwidth allocated to the cll.

This service can be turn on or off. This is a typical assurance intent.
