Shared point-to-multipoint TLS circuits provide for greater flexibility from the service providers point of view. This allows for a large bandwidth circuit to be created and additional drops to be added as customers are acquired. Careful monitoring of bandwidth requirements prevent one drop from starving the others. This is why QoS is important.

One of the best solutions for this design is in distributed campus models, where the customer has a need for a large bandwidth connection between multiple geographically dispersed sites.

Figure illustrates a shared multipoint TLS solution interconnecting three remote sites on the right with the central site on the left.
