A Revenue-Based Bandwidth Sharing for Advance and Immediate Reservation Calls

To guarantee the timely provisioning of QoS to real-time oriented multiparty and distributed computing applications (e.g., video conferencing and grid computing) that require the utilization of time and quantity-related resources, the resource should be reserved in advance. However, this new type of reservation (i.e.. advance reservation) may collide with legacy (i.e.. immediate) reservations that do not specify their session duration. In this paper. to suggest a balanced solution between sharing pools of resources and the managing of collisions between reservation calls, a revenue-based resource sharing scheme (focusing on the bandwidth) is proposed. The proposed scheme attempts to avoid possible collisions by employing a virtual profile of resources reserved in advance in an effort to achieve enhanced resource utilization. It is shown through NS-2 [22]-based network simulations that the proposed scheme can achieve balanced performance when compared with other schemes. including static resource partitioning and complete resource sharing.
