Networking Vendor & Open-Source Reference Library

This page is a verified index of primary sources for computer networks: official documentation, developer and API portals, source repositories, SDKs, downloadable or offline documentation, a two-track learning path, and free-access research literature.

It is a navigation layer, not a tutorial. Where the rest of this book explains a concept, this page tells you which document to open to get the authoritative answer, and in what order to read things. Every link was HTTP-verified on the date shown below; sources that block automated checkers but work in a browser are flagged rather than silently dropped.

196 vendors and projects plus 196 education & reference-implementation resources, across 18 categories — documentation, developer portals, GitHub orgs, SDKs, and downloadable/offline doc bundles, plus 16 video resources and 9 conference sources.

Every link was HTTP-verified on 2026-10-07. Direct PDF links were additionally verified by content-type.

Verification caveats. Some sites return 403/406 to automated clients but load fine in a browser: Arista, Cisco, Juniper, Ciena, Dell, Huawei, Intel, Ericsson, Keysight, UfiSpace, Cacti, Aruba/HPE, Equinix, Allied Telesis, ui.com, APNIC Academy, NANOG. Two require a login (Mist API portal, Radware support) and return 401. The Ansible and Zeek documentation sites rate-limited our checker (429) rather than failing. savannah.nongnu.org and trex-tgn.cisco.com were unreachable from our network, so GitHub entry points are given for lwIP and TRex.

Video courses, channels & talks

16 resources across 2 groups. Every channel and playlist below was fetched and title-verified on 2026-10-09. Handles drift and several plausible-looking handles resolve to the wrong channel, so a 200 response is not proof of identity — the links here were each checked against the channel title.

Channels & conference recordings

• Practical Networking — Packet-level Wireshark and tcpdump walkthroughs — the closest thing to a lab bench on video.
• NetworkChuck — Fast, entry-level networking (CCNA, Wi-Fi, VPNs); good for momentum, verify the details.
• David Bombal — Long-form Wireshark, Python for network engineers, and vendor-neutral labs.
• RIPE NCC — RIPE meeting recordings: routing, RPKI, BGP operations at real operator depth.
• IETF — Working-group sessions and tutorials given by RFC authors — primary-source video.
• USENIX — Conference recordings for most USENIX papers — free video, the fastest route into a systems paper.
• The Linux Foundation — The Linux Foundation channel: kernel and LF event recordings.
• ACM — ACM channel: SIG talks and TechTalks, including SIGCOMM/SIGMOD-adjacent material.
• InfoQ — Conference keynotes and architecture talks — good for orientation, verify specifics elsewhere.
• netdevconf — Official netdev conference recordings — kernel networking, the dev room of record for Linux networking.
• SIGCOMM — ACM SIGCOMM channel; thin, but it carries the occasional full-session recording.
• Tech Field Day — Vendor-engineer roundtables on networking, wireless and infrastructure; unscripted Q&A, verify claims.
• Google TechTalks — A large archive of university and internal talks, including a lot of systems and networking material.

Lectures & playlists

• Stanford CS144 — Introduction to Computer Networking — McKeown and Levis, complete; the best free networking course on video.
• Stanford CS144 — Routing unit — The routing half of CS144 as standalone short videos.
• Stanford CS144 — Philip Levis & Nick McKeown (older run) — An earlier full run of the same course, useful when a lecture is missing from the newer playlist.

Note: Networking video skews either to certification prep or to operator conference footage; both are here, and both need checking against the RFC.

Conference videos, notes & archives

9 resources across 2 groups. Conference recordings are the primary-source tier of video: the speaker is usually an author of the paper, and where a talk exists the proceedings entry is often open at the same link. Every URL here returned 200 on 2026-10-09 unless the note says otherwise.

Networking is unusual: the operator conferences (RIPE, NANOG, netdev) publish more usable video than the academic ones.

Conference channels & video archives

• netdev conference — Slides and video for every netdev talk — the Linux kernel networking conference.
• USENIX NSDI ’25 — Previous edition; NSDI papers are the reference point for anything about transport and forwarding.
• IETF meetings — Recordings, slides and minutes for every working-group session — primary source for protocol design.
• RIPE meetings — RIPE NCC site: meeting archives, policy documents and operator training material.
• FOSDEM video archive — Free, complete, and organised by devroom — the networking and routing devrooms are the useful ones.
• FOSDEM schedule — The searchable schedule; video lands on the archive above within days.
• media.ccc.de — Chaos Computer Club congress archive with slides and subtitles; the network-infrastructure tracks are here.
• NANOG — NANOG meeting presentations. Verify currency: the site returns 403 to automated checkers but works in a browser.

Notes, proceedings & paper-adjacent archives

• USENIX ;login: — The USENIX magazine — practitioner write-ups that read like conference talks without the video.
