If I understand #SCTP multihoming correctly, in a multi-WAN scenario, it would likely suck on #LegacyIP because internal hosts usually don't have a NAT44 address routed through each ISP.

But on #IPv6, multiple addresses is the norm and I think an RA could advertise every ISP's IPv6 prefix, allowing hosts to be aware of their public IPs, thus do sensible SCTP multihoming.

That sounds awesome! What am I missing, besides application support for SCTP?

dc.send(file) не существует: что на самом деле нужно для передачи файла в браузере

dc.send(file) не означает, что файл уже доставлен. Между отправкой и реальной доставкой – буфер, relay, запись на диск, ACK, reconnect и потерянный после refresh File. Разбираю шесть production-проблем WebRTC-файлообмена, которые обычно остаются за пределами туториалов.

Рис. 1. dc.send(file) не означает, что файл уже доставлен. Самая опасная иллюзия в WebRTC-файлообмене выглядит примерно так: const dc = pc.createDataChannel('file'); for (let offset = 0; offset <...

🌘 RACK 演算法助攻：Pion SCTP 傳輸速度提升 71%，延遲大幅降低 27%
➤ 突破即時通訊瓶頸：RACK 如何重塑 WebRTC 的可靠資料傳輸架構
✤ https://pion.ly/blog/sctp-and-rack/
Pion 開源專案近日宣佈，透過導入 RACK（Recent Acknowledgment）遺失偵測演算法，其 SCTP 實作效能取得了突破性進展。在 RACK 模式下，SCTP 的吞吐量從原本的 234 Mbps 躍升至 316 Mbps，且在標準化 CPU 使用率後，每單位 CPU 的傳輸效率提升了約 71%。這項優化解決了傳統 SCTP 在處理封包遺失時的低效問題，特別是針對 WebRTC 資料通道（Data Channels）中的即時通訊情境。本文將剖析 Pion 如何藉由時間信號取代傳統序號邏輯，並利用尾端遺失探測（TLP）機制，確保在網路波動下仍能維持穩定的高速傳輸。

RACK makes Pion SCTP 71% faster with 27% less latency | Pion

In the RACK profile, SCP sustained 316 Mbps using ~0.044 CPU seconds, compared to 234 Mbps at ~0.056 CPU seconds before RACK. When normalized for CPU usage, this corresponds to a ~71% improvement in throughput per CPU, while max-burst CPU profiles remain comparable.

#sctp 31: Many #crypto bros pretend that #bitcoin solves the "double spend" problem, aka the "byzantine general problem." This is one of the many deceptions they weave about the technology.

#SCTP 30 - People ask if you don't believe in #bitcoin or #crypto, why not short it?

#SCTP 29 - What does it take to admit we're wrong about #bitcoin and #crypto? This is a super simple question and answer that most crypto bros want to ignore....

#SCTP 28 Another common talking point: #Bitcoin is "censorship resistant" which is utterly meaningless when it operates on a digital network controlled by the very central entities it claims it can bypass, and any network administration will tell you how trivially easy it is to block #crypto traffic if so desired.

#SCTP 27 - Probably one of the most common stupid crypto talking points: ad hominem attacks on anybody who disagrees with #crypto and #blockchain being the next big thing.
