Media production networks require an ecient collaboration between geographically distributed actors and oer predictable workloads, making it possible to exploit this predictability and use advance bandwidth reservation services to achieve greater bandwidth utilization and service guarantees. To oer reliable reservations, the incorporation of fault-tolerance related features in bandwidth reservation strategies is a necessity, although this imposes a waste of capacity and extra performance overhead. As a rst provisional stage to oer a robust reservation system, deploying protection mechanisms ensures that the reservations remain valid when the system is in operation. To maximally utilize the network, and to ensure there is a quick response in a dynamic network environment, constant monitoring and optimization is needed. In this article, we propose an ecient dual optimization approach consisting of two consecutive processes. First, a schedule is produced by a resilient advance reservation algorithm. Then, the generated schedule is continually updated over time using a runtime adaptation approach in order to be capable of dynamically adapting the network to changing conditions and mitigating the side eects of provisioned reliability. This step uses the interconnecting network links' leftover capacity, resulting in an increased performance both in steady and unsteady network conditions. Our evaluations show that in failure-prone environments, the proposed approach leads to signicant increase in the success rate of admitted requests, up to 6.77 times, compared to the resilient advance reservation algorithms.
