Protocol Stack
The layered rules — TCP/IP, HTTP, TLS — that determine whether data arrives intact, not what data is sent.
Network performance is measured by throughput, latency, and uptime — outputs that confirm data moved, not whether the rules governing how it moved protected the people it passed through.
The enforcement behavior of the protocol stack itself: whether TLS is terminating where it should, whether HTTP headers are stripping identity signals, and whether the routing layer is neutral across content types and senders.
When we measure the protocol layer instead of the traffic layer, we can distinguish a fast network that is quietly discriminating from a slower one that is structurally neutral — a distinction invisible to throughput metrics alone.
End users, privacy advocates, and smaller content providers who gain standing to demand neutrality guarantees that do not depend on trusting the carrier's intentions.
Telecommunications carriers and large CDN operators who resist protocol-layer transparency because it would expose where quality-of-service rules are applied, making traffic shaping and paid prioritization structurally visible rather than commercially deniable.
A network neutrality rule that applies only to traffic content while leaving protocol-layer enforcement unaudited governs the water but not the pipes — structural discrimination remains legal by remaining invisible.
The FCC's open docket system accepts public comments on rulemaking. Search 'net neutrality' at fcc.gov/ecfs and submit a comment naming the protocol layer as the enforcement site that transparency rules must reach.
Tools like Cloudflare's ESNI checker or the EFF's Cover Your Tracks let you see what your protocol stack is actually revealing about you to your ISP and to the sites you visit.
Dozens of municipalities run their own protocol infrastructure. Contact your city council member or county board to ask whether a municipal fiber feasibility study has been conducted — and if not, request one.
The IETF publishes working group agendas and accepts public comment on protocol drafts at ietf.org. Subscribing to a relevant mailing list is free and places you inside the room where structural rules are written.
