Airavat: An Agentic Framework for Internet Measurement
This paper presents Airavat, the first agentic framework that automates the generation and systematic verification of Internet measurement workflows by coordinating specialized agents to match expert-level solutions while ensuring methodological correctness against decades of research standards.

Imagine you are a detective trying to solve a massive mystery about how the internet works. You have a garage full of specialized tools: a BGP analyzer (like a traffic cop), a traceroute processor (like a GPS tracker), and a performance monitor (like a speed camera).
The Problem:
In the past, if you wanted to solve a mystery like "Why did the internet break in Africa?" or "How did a hurricane affect global data?", you had to be a master detective. You needed to know exactly how to use every single tool, how to connect them together, and how to make sure you didn't accidentally use the wrong data. It took experts days or weeks to build the right "investigation plan" (workflow).
Even worse, if you built a plan that looked perfect on paper but had a tiny logical flaw (like forgetting to filter out a fake route), your investigation would give you the wrong answer, and you wouldn't even know it until it was too late.
The Solution: Airavat
The paper introduces Airavat, which is like a super-smart, automated detective agency that helps you solve these internet mysteries.
Here is how Airavat works, using a simple analogy:
1. The Team of Specialized Agents
Instead of one giant brain trying to do everything, Airavat uses a team of four specialized "agents" (AI assistants) that act like a human expert team:
- The Detective (QueryMind): You tell it your question in plain English, like "What happened to the internet when that undersea cable broke?" The Detective breaks this big, scary question down into small, manageable clues (e.g., "Find the cable," "Find the countries it touches," "Check the traffic").
- The Architect (WorkflowScout): This agent looks at the clues and designs a blueprint. It asks, "Do we need a GPS tracker or a speed camera for this clue?" It decides the best way to solve the puzzle, often creating a few different plans just to be safe.
- The Builder (SolutionWeaver): This agent takes the blueprint and actually writes the computer code to run the tools. It connects the tools together so they talk to each other correctly.
- The Librarian (RegistryCurator): As the team solves problems, the Librarian writes down the tricks they learned so they can use them again later.
2. The Safety Net: The Knowledge Graph
This is the most important part. Usually, AI can write code that looks right but is logically wrong. Airavat has a Knowledge Graph, which is like a massive, digital library containing 50 years of research papers on how to measure the internet correctly.
- The Verifier (The Fact-Checker): Before the code runs, a "Fact-Checker" agent reads the plan against the library. It asks: "Hey, in 1995, researchers found that if you don't filter out these specific fake routes, your results are garbage. Did you remember to do that?" If you didn't, the Fact-Checker stops the plan and fixes it.
- The Validator (The Stress-Tester): This agent asks, "How do we know this plan actually works?" It finds other ways to double-check the results, like comparing your findings to historical data or using a different method to see if you get the same answer.
3. What Happens in Real Life?
The researchers tested Airavat with four different "cases":
- Case 1 (The Copycat): They asked Airavat to solve a problem that a human expert had already solved. Airavat built a plan that matched the human expert's results perfectly, even though it had never seen the human's solution before.
- Case 2 (The Smart Shopper): They asked it to analyze disasters. Airavat realized it didn't need to use five different complex tools; one simple tool could do the job. It saved time and effort by not over-complicating things.
- Case 3 (The Explorer): They asked it to solve a brand new problem that no one had ever solved before (cascading cable failures). Airavat built a complex plan from scratch, connecting tools in a way that would have taken a human expert days to figure out.
- Case 4 (The Trap): They gave Airavat a tricky question where the answer depended on a tiny, hidden detail (filtering out a "default route").
- Without Airavat's safety net: The AI wrote code that ran perfectly but gave the wrong answer because it missed that tiny detail.
- With Airavat's safety net: The "Fact-Checker" looked at the plan, remembered a rule from the library, and said, "Wait! You forgot to filter the default route!" It fixed the code automatically, turning a 0% correct answer into a 90%+ correct answer.
The Big Picture
Airavat is like a "Copilot" for internet researchers.
- For Experts: It acts as a force multiplier. It does the boring, repetitive work of connecting tools and checking for errors, letting experts focus on the big ideas.
- For Non-Experts: It acts as a scaffold. It lets someone without a PhD in networking ask a question in plain English and get a professional-grade investigation plan back in minutes, not weeks.
The paper concludes that while AI can't replace human judgment entirely (especially for brand-new, never-before-seen problems), it can automate the heavy lifting and ensure that the "investigation" is built on solid, proven ground. It turns the internet from a black box that only a few can understand into a system anyone can measure and learn from.
