🌘 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。

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.

Here's a deeply nerdy talk I gave about sending lidar data over webRTC data channels using 5g.

#SCTP 26: People argue that more fiat is used in crime than #crypto, but this is misleading. Fiat has tons of legit uses. Crypto does not, and as a percentage of criminal activity #cryptocurrency is more crime-adjacent.

#sctp 25: #crypto bros will often create distractions when debating about #blockchain by suggesting its critics are jealous
