The complexity of managing multi-domain research networks makes automation not just convenient but essential.
Science DMZ and Data-Intensive Research
A recurring theme was the Science DMZ architecture—a network design pattern creating friction-free paths for large-scale data transfers. Researchers presented compelling case studies, including how a multi-petabyte environmental monitoring dataset was transferred between institutions in different countries, something logistically impossible just years ago.
These infrastructures are becoming essential as machine learning models grow larger and training datasets become more diverse. The ability to move data efficiently between institutions and compute facilities is increasingly critical.
Workshop Experience: AI in Software Development
One of the highlights of my APAN59 experience was participating in an intensive workshop focused on artificial intelligence applications in modern technology workflows. The workshop brought together participants from diverse backgrounds—network engineers, researchers, developers—to explore how AI is transforming various aspects of our work.
As part of the workshop format, each participant contributed by presenting on a specific topic. I took on the challenge of exploring AI’s impact on software development practices, an area that increasingly intersects with the network infrastructure challenges many APAN attendees face daily.
Exploring the Development Landscape
My presentation examined how AI is reshaping multiple dimensions of software development:
Intelligent Code Assistance: I discussed how large language models now offer sophisticated code generation, going far beyond simple autocomplete to suggesting entire function implementations and helping developers work with unfamiliar frameworks. These tools significantly accelerate development, particularly for routine tasks.
AI-Driven Testing and Quality: The session covered how AI-powered testing tools can generate comprehensive test cases, identify edge cases human testers might miss, and predict bug-prone code sections based on historical patterns. ML models trained on large codebases can flag problematic patterns before they reach production.
Design and User Experience: I touched on emerging tools using AI to generate design mockups from natural language descriptions, optimize layouts for accessibility, and predict user interaction patterns—accelerating iteration cycles and helping developers create more usable interfaces.
Security and Code Review: The presentation highlighted how AI-powered static analysis tools are becoming more sophisticated, identifying not just syntax issues but semantic vulnerabilities and security weaknesses that might escape traditional review processes.
Connecting to Research Software
Given our audience of research network professionals, I emphasized the particular relevance for research software engineering. Many scientific applications are developed by domain experts without formal software engineering training. AI-assisted development tools can bridge this gap, helping create robust, maintainable code while focusing on scientific questions.
The workshop discussion that followed was energetic and insightful. Participants shared both positive experiences and thoughtful concerns about AI development tools. We explored important considerations around code quality, the necessity of understanding what AI-generated code actually does, and questions about intellectual property when using these tools.
The collaborative format made the workshop particularly valuable—each presentation sparked discussions that connected different perspectives and use cases, creating a richer understanding than any single presentation could provide.
Innovation and Broader Impact
While APAN59 was primarily technical, several sessions naturally addressed how advanced networks and digital technologies support broader development goals. Presentations highlighted how reliable, high-capacity networks serve as foundational infrastructure for education, healthcare, and economic development.
