A new proposed model has been implemented to guarantee the required voice quality based on the available network resources. Although, the proposed model is so simple from the routers side, it is somehow complex from the host side due to the input analyzing process. On the other hand, the QBone (quality of service backbone) model moves the complexity to the router side. Practically, the QBone model does not face any success because most of the users are not willing to pay much money to have voice sessions across the Internet. So, the proposed model not only guarantees the voice quality but also saves the network resources (up to 74% of the consumed bandwidth).
