SUMMARY:P4 Developer Days - AR/CG Network Traffic Classification in Programmable Dataplane
DESCRIPTION:P4 Developer Days webinar\, “AR/CG Network Traffic Classification in Programmable Dataplane”\nDate: November 12\, 2025\nTime: 8:00am Pacific \nVIEW VIDEO \nVIEW SLIDES \nAbstract\nIn this presentation\, we explore the importance of classifying AR/CG traffic directly within the network device to enable low-latency\, intelligent forwarding. We outline the end-to-end process of feature extraction and deployment within a programmable data plane\, focusing on how key traffic features are computed and mirrored in P4-enabled switches. We also discuss the training of machine learning models tailored for the P4 data plane and their use in online pattern matching. Finally\, we introduce our key contributions\, including the extracted features\, developed codebase\, and publicly available repositories. \nSpeaker\nAlireza Shirmarz received his B.Sc. in Computer Engineering from Shahed University in 2009 and his M.Sc. in Network Engineering from Amirkabir University of Technology (Tehran Polytechnic) in 2014. He earned his Ph.D. in Computer Engineering from IAU-Tehran North Branch in 2020. Since 2014\, he has been actively teaching undergraduate courses in computer science and engineering and has been involved in graduate and Ph.D. supervision since 2020. \nHis research focuses on the intersection of networking and AI/ML\, particularly in optimizing Quality of Experience (QoE) for real-time and interactive applications in future networks\, including 6G. He specializes in intelligent data plane solutions\, SDN architectures\, and QoS/QoE management. Currently\, he is a Postdoctoral Researcher at UFSCar\, advancing AI/ML applications in networking. \n

SUMMARY:P4 Developer Days - Implementation of Periodic Behavior with P4: Challenges and Solutions on Intel Tofino with Application in Time-Sensitive Networking (TSN)
DESCRIPTION:P4 Developer Days webinar\, “Implementation of Periodic Behavior with P4: Challenges and Solutions on Intel Tofino with Application in Time-Sensitive Networking (TSN)” \nView Slides \nView Video \nAbstract\nImplementing periodic time behavior in hardware data planes is challenging due to limited arithmetic capabilities such as the lack of modulo operations\, restricted timestamp precision\, and resource constraints. This talk presents a general mechanism for implementing periodic time logic in P4\, i.e.\, enabling data plane behavior that repeats in fixed time intervals\, applicable to a broad range of time-aware applications. The mechanism enables periodic packet matching by mapping absolute timestamps to relative positions within a hyperperiod. To emulate hyperperiod boundaries\, we leverage the switch’s internal packet generator to generate periodic trigger packets that act as time anchors for computing relative timestamps. \n\nAs a concrete use case\, we apply this mechanism to implement Per-Stream Filtering and Policing (PSFP) as defined in IEEE 802.1Qci. Our implementation on Intel Tofino™ hardware demonstrates reliable time-based gating at line rate. Finally\, we discuss how this periodicity mechanism can be extended to implement additional time-sensitive features such as the Time-Aware Shaper (TAS)\, offering a scalable foundation for deterministic network behavior in P4-based systems.\n\n\nSpeaker\nFabian Ihle received his bachelor’s (2021) and master’s degrees (2023) in computer science at the University of Tuebingen. Afterwards\, he joined the communication networks research group of Prof. Dr. Habil Michael Menth as a Ph.D. student. His research interests include software-defined networking\, P4-based data plane programming\, resilience\, and Time-Sensitive Networking (TSN). \n\n
