P4TC Provisioning And Runtime Control API

Abstract
The P4TC Control APIs consist of two primary interfaces built on the netlink framework: one for provisioning P4 program manifestations in the Linux kernel and another for managing the P4 runtime. This talk focuses on the P4TC runtime, which employs P4 annotations to link datapath constructs with the control plane. These annotations are converted by the compiler into a JSON format, allowing runtime control applications to introspect both control and data path constructs.
Architecturally, the P4TC runtime API is inspired by the REST paradigm, employing resource-oriented paths as nouns and a refined set of verbs. The verbs follow CRUD (Create, Read, Update, and Delete) principles and include specialized extensions for event publish-subscribe functionality. By using “paths” to target specific datapath objects, the API remains agnostic regarding the nature of those objects – implying a control application does not need to change for multitudes of P4 programs.

For more than twenty years, Jamal Hadi Salim has been a leader in the evolution of networking and Software-Defined Networking (SDN). He is a major contributor to the Linux kernel networking subsystem and the current maintainer of the Traffic Control (tc) subsystem. Currently, he leads the P4TC initiative, which enables P4 programs to run directly within the Linux kernel.
His previous leadership roles include serving as the chair for the IETF SDN working group on Forwarding and Control Element Separation (ForCES). During his tenure, he developed a ForCES implementation used in large-scale telecommunications and authored multiple SDN standards. Currently, Jamal is concentrating on the performance of AI/ML, with a specific emphasis on networking protocols and infrastructure.

EdgeP4: In-Network Edge Intelligence for a Tactile Cyber-Physical System Testbed Across Cities

Abstract
Tactile 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 designed 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.
The 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.

A Multi-Site Testbed for Heterogeneous P4 Data Plane Experimentation on Research Cyberinfrastructure

Abstract
This presentation introduces a multi-site testbed that unifies three distinct classes of P4-programmable hardware, FPGA SmartNICs (AMD Alveo), DPUs (NVIDIA BlueField), and software switches (BMv2), under a single Kubernetes control plane on the National Research Platform (NRP). We detail the architecture that uses ESnet’s SENSE orchestrator for dynamic multi-domain Layer 2 path provisioning and a unified shell automation framework for reproducible experiments. We also share critical lessons learned from integrating heterogeneous targets and running a real-world deployment. This work provides a blueprint for building and operating advanced, reproducible P4 experimentation infrastructure for the research community.

P4Check: a P4 Verification Tool

Abstract
We present P4Check, a scalable and practical one-stop shop for verifying data planes defined in P4. P4Check combines well-proven techniques, symbolic execution, big-step semantics and model checking with a novel high-level specification language into a tool to verify properties of stateful P4 programs at both the device and network levels. We present case studies showing property verification and bug detection for real-world P4 programs and conduct experiments to quantify the performance of p4Check compared to earlier works.

MORP4: A Dynamic Network Telescope

Abstract
A network telescope passively monitors unsolicited traffic reaching unused Internet address space advertised to the global routing system. For more than two decades, network telescopes have allowed unique global visibility into a wide range of Internet phenomena. However, telescopes are afflicted by two main issues: progressive erosion due to IPv4 space unavailability and blacklisting. To overcome these issues, we propose MORP4, a programmable data-plane framework implementing a “dynamic” network telescope.
MORP4 accurately and adaptively tracks unused space of an organization’s network with configurable time and space granularity and captures only traffic directed towards unused addresses at line rate. We provide an implementation in P4 and Python/C++, and deploy it on a Tofino switch. We show that it can detect unused IPv4 address space at the finest granularity (/32) while operating at line rate and provide an effective approach for operating a telescope in the IPv6 domain.
