High-Precision Networking Services: Problems, Approaches, and Opportunities
Alexander Clemm · IEEE Transactions on Network and Service Management · 2022
One of the next waves of networking innovation is expected to be driven by the needs of applications that require communication services with stringent service level guarantees, for example near-deterministic and ultra-low end-to-end latency. Providing such services is riddled with challenges due to limitations with existing QoS mechanisms and application characteristics that are not tolerant of even slight degradation. In addition, to be deployable in practice, advances in accounting technology to be able to verify compliance of services with their guarantees will also be sorely needed, resulting in a separate set of challenges. This industry vision paper provides an overview of the problems, highlights some solution approaches, and articulates a set of very practical research challenges that, when successfully addressed, will have significant practical impact.
