On Bandwidth Reservation for Optimal Resource Utilization in High-Performance Networks

SESSION: Doctoral Showcase - Early Research Showcase

EVENT TYPE: Doctoral Showcase

TIME: 3:30PM - 5:00PM

SESSION CHAIR: Wojtek James Goscinski

Presenter(s):POONAM DHARAM


The bulk data transfer needs in network-intensive scientific applications necessitate the development of high-performance networks that are capable of provisioning dedicated channels with reserved bandwidths. Depending on the desired level of Quality of Service (QoS), some applications may request an advance reservation (AR) of bandwidth in a future time slot to ensure uninterrupted transport service, while others may request an immediate reservation (IR) of bandwidth upon availability to meet on-demand needs. The main issue in these networks is the increased possibility of preempting ongoing IRs at the time of the activation of an AR due to the lack of available bandwidth. Such preemptions cause service degradation or discontinuity of IRs, hence impairing QoS promised to be provided for IRs at the time of their reservation confirmation. We propose a comprehensive bandwidth reservation solution to optimize network resource utilization by exploring the interactions between advance and immediate reservations.
