SUMMARY:P4 Developer Days – OpenDesc: Describing NIC-Host Interfaces
DESCRIPTION:Register to attend this P4 Developer Day webinar on April 30 at 11 am ET/5 pm CET \nOpenDesc: Describing NIC-Host Interfaces\n\n\nAbstract\nModern NIC hardware is increasingly expressive\, yet host software remains shackled to static\, device-specific descriptors and ad-hoc glue layers. We present OpenDesc\, a framework that leverages P4 to define the interface between host and NIC. By treating software intent and hardware capabilities as negotiable P4 programs\, OpenDesc automatically compiles minimalist\, application-specific driver datapaths for metadata. This approach eliminates the “lowest common denominator” bottleneck\, enabling seamless metadata exchange and hardware-software co-design across heterogeneous NIC architectures. \nSpeaker\nSeyyidahmed is a systems researcher at imec. His research interests include the co-design of programmable hardware and high-performance networking stacks\, with a focus on improving the flexibility\, programmability\, and efficiency of modern networked systems. \n\n\nRegister to attend this virtual & free event

SUMMARY:P4 Developer Days – EdgeP4: In-Network Edge Intelligence for a Tactile Cyber-Physical System Testbed Across Cities
DESCRIPTION:Register to attend this P4 Developer Day webinar on May 20 at 11 am ET/5 pm CET \nEdgeP4: In-Network Edge Intelligence for a Tactile Cyber-Physical System Testbed Across Cities\n\n\nAbstract\nTactile Internet based operations\, e.g.\, telesurgery\, rely on the human operator for end-to-end closed loop control to achieve accuracy. While feedback and control are subject to network latency and packet loss\, critical operations such as pose correction\, fiducial marking\, tremor reduction\, etc. are tasks that should be carried out automatically and thus dispensing with these feedback signals from traversing the network to the other end. We design two edge intelligence algorithms hosted at P4 programmable end switches placed 400 km apart. These algorithms locally compute and command corrective signals. We implement these algorithms entirely on the data plane on Netronome Agilio SmartNICs. “pose correction” is placed at the edge switch connected to an industrial robot gripping a tool. \nThe round trip between transmitting force sensor array readings to the edge switch and receiving correct tip coordinates at the robot is shown to be less than 100µs. “tremor suppression” is placed at the edge switch connected to the operator. It suppresses physiological tremors\, which improves the application’s performance and also reduces the network load up to 99.9%. Our EdgeP4 framework allows edge intelligence modules to seamlessly switch between the algorithms based on the tasks being executed by devices connected to their ports. \n\nSpeaker\nDeepak Choudhary is currently a master’s student and a research assistant at Aalto University\, Finland. His research interests primarily lie in Systems and Networking\, specifically in software-defined networking and programmable data planes. Previously\, he spent 2.5 years as a research assistant at the Indian Institute of Science (IISc). His work there focused on developing a P4-programmable Time-Sensitive Networking (TSN) switch and testing them on wide-area network testbeds. \n\nRegister to attend this virtual & free event
