The paper Towards the Integration of TAPRIO-based Scheduling with Centralized TSN Control by George Papathanail, Lefteris Mamatas and Panagiotis Papadimitriou, from University of Macedonia, and with acknowledgement to NEPHELE, was accepted and presented at the 3rd International Workshop on Time-Sensitive and Deterministic Networking (TENSOR 2023).
Time-Sensitive Networking (TSN) aspires to provide a solid underpinning for meeting latency guarantees across traffic classes with diverse requirements. Despite the emergence of various specifications from the TSN family of standards, there is a shortage of prototype implementations with support for both TSN-based scheduling and its configuration by a Centralized Network Controller (CNC).
This paper presents the design and implementation of a TSN platform that couples Time-Aware Priority Shaper (TAPRIO) with CNC. The CNC is utilized to convey TSN schedules into TAPRIO using NETCONF and YANG. This platform is used by the authors to assess the impact of TAPRIO on the latency and jitter experienced by scheduled traffic. Their results corroborate the proper operation of TAPRIO and its efficient interaction with the CNC.
TENSOR 2023 was part of IFIP Networking - organised by the International Federation for Information Processing (IFIP) in Barcelona (Spain) - and took place on 12-15 June 2023. Besides the paper presentation, Panagiotis Papadimitriou was also co-chair of TENSOR, which went very well with high participation and a lot of discussions stimulated by the various talks.
