Hi, I'm Gaetano
I design data center and WAN networks at Cisco (CCIE #62461). Before that I spent years on congestion control for low-delay communication (WebRTC/GCC, QUIC, AQM). These notes are the pieces I found worth writing down: designs, automation and research.
Not a weekly blog. When something is useful, I publish it. If you want the short version of who I am, start with About and the research notes.

How I track ACI scale beyond the APIC Capacity Dashboard: VLAN encaps, Python extract, Splunk.
-
The WebRTC / GCC work: adaptive threshold, Chromium patches, and why delay-based control matters.
-
A Python tool that holds a target CPU load with a PID regulator, for performance tests and thermal runs.
Research Highlights
Transport Protocols & Congestion Control
Ph.D. work on low-delay communication: Google Congestion Control for WebRTC, QUIC vs HTTP/1.1/2, and AQM (PIE, CoDel, SFQ). Notes plus selected papers, including IEEE/ACM ToN 2017.
