My statement

Many systems and networking conferences have a special operational systems track for papers describing the design, implementation, analysis, and experience with large-scale, operational systems and networks. Different from regular research papers, such operational papers need not present new ideas or results to be accepted; indeed, new ideas or results will not influence whether the papers are accepted. Given very different review criteria, I explicitly mark my operational systems track papers in my website and CV. I promise the systems and networks described in these papers really serve (or have served) customer workloads in production environments.
