SLA request
BB maintains the SLAs in the database and deletes them after the period is over.
When a new SLA request is made, the BB compares the request service type, rate and drop probability to the SLAs already in place.
- If no comparable request exists, the BB sends a configuration message to the egress router to set up a new class with the parameters specified. It also assigns a DSCP for the class.
- If a similar request exists, no configuration messages are sent.
- An SLA ID is returned to the customer, which will be used in the BAR requests.
