An experimental platform for edge to cloud research

This past month brings 2025 to a close and also exciting updates, including a year in review, Trovi improvements, and a CHI@Edge artifact, along with announcements about upcoming webinars (next up: How to Organize Artifact Evaluations (AEs) with Shared Infrastructure on Jan. 13th), our call for presentations for our sixth user meeting at NCAR’s campus in Boulder, and highlights from our newly appointed reproducibility ambassadors.

Modern networks are growing increasingly complex, and managing them effectively requires sophisticated policy configurations that can adapt in real-time. Languages that enable direct programmability of network data planes, like P4, offer unprecedented control over packet processing, but come at a steep learning cost. This raises a crucial question: can we automate the generation of these complex network policies while ensuring they're correct, efficient, and adaptable? NetPrompt is a novel framework that harnesses the power of Large Language Models (LLMs) to automatically generate and optimize P4 scripts for Software-Defined Networks (SDN). Read more to learn how the research team implement NetPrompt using Chameleon.

It's the end of the year, so that means it's time for our annual Tickets of the Year blog! This blog covers some of our most common help desk tickets and provides solutions, so it can hopefully be a helpful reference if you run into any of these problems. If you need more help, the best places to look would be the docs, the FAQ, or submitting a new ticket to the help desk.

The Sixth Chameleon User Meeting will be held April 15-16, 2026 at the NCAR Mesa Lab in Boulder, Colorado. This year's meeting's theme focuses on computer science research and education in Artificial Intelligence (AI) and Machine Learning (ML). The objective of the meeting is to create a community discussion on AI research, approaches to education, and most importantly what platform you need – or may need in the future – to solve the hard problems and train the workforce of the future. We invite researchers and educators using Chameleon to submit presentation proposals sharing their experiences. Come to network with scientists working on similar topics, share tips on how to muster resources and data for hard-to-get experiments, and find materials and digital artifacts to teach AI classes!

As in previous years, we will reimburse travel expenses of up to $1,500 for the presenting authors of the top 10 selected abstracts (one author per abstract).
