Design of a dynamic adaptive reservation system in media production networks

Abstract

Due to the predictable nature of network transfers in media production industry, advance bandwidth reservation results in higher bandwidth utilization and improved network performance. However, in unreliable networks, this may fail. As a first provisional stage, deploying protection mechanisms ensures that the schedule remains valid when the system is in operation. Constant monitoring and modification is also required in order to be capable of dynamically adapting the network to changing conditions. In this paper, we propose an efficient dual approach consisting of two 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. As this step uses the interconnecting network links' leftover capacity, following this approach leads to increased performance in case of steady network conditions, or neutral performance when transmitting admitted requests in uncertain network conditions.
