🚗💨 Welcome to the wild world of #UDP, where "unreliable" is just a fancy way of saying "convertible" because who doesn't want their #data packets feeling the breeze? 🌬️ Apparently, when it's raining data, you just slap on a roof and cross your fingers. 🤞 Because that's totally how reliability works, right? 😂

UDP Isn't Unreliable, It's a Convertible

🌘 UDP並非不可靠，而是可轉換：掌握彈性的網絡傳輸
➤ UDP：彈性與自由的網絡傳輸協定
✤ https://www.proxylity.com/articles/udp-is-a-convertible.html
此文章挑戰了「UDP不可靠」的普遍觀念，將UDP比喻為可開篷跑車，提供極大的彈性與自由。作者解釋，UDP的「不可靠」實質上是指它不內建TCP那樣的可靠性機制，如序號、確認應答等，而是讓開發者自行建置。這種設計使得UDP在需要客製化可靠性需求的場景（如遊戲、音訊串流）中，能以更輕量、高效的方式實現，達到與TCP相當甚至更好的效能。文章強調，UDP的彈性纔是其核心優勢，使用者可以根據實際需求，像控制跑車車篷一樣，選擇性地添加可靠性功能。
+ 這個比喻太精妙了！終於理解UDP的真正價值所在，原來不是不可靠，而是我們可以自己決定可靠的程度。
+ 作者點出了關鍵！UDP的優勢在於客製化，而不是被動接受TCP的重載。對於需要低延遲的應用來說，這太重要了。

Target and Discovery Configuration Options for “nmap”

The nmap command contains numerous configuration options for port scanning operations, as appropriate and as necessary. The options and parameters include -iL for input from host and network list file names, -iR for random targets, --exclude for exclusion of hosts and networks, and --excludefile for the exclusion of lists from files. Host discovery options include -sL for list scans, -sn for ping scans (disabling the port scans), -Pn to assume complete operations online, and additional […]

The new enclosure is almost complete! At 6cm across by 10cm deep and 4cm tall it is as small as we can make it with the current hardware specs. We continue to make improvements to the software as well, so #osc communication over #udp is faster and more reliable. All so you can sonify whatever you attach this to, human, animal, or machine!

Check out the GitHub for the project here: https://github.com/scottericpetersen/CAFFEINE

TCP and UDP are both Internet protocols used for transferring data, but they differ in reliability and speed.

#TCP stands for Transmission Control Protocol, which is a connection-based protocol that ensures reliable and ordered data delivery between devices.

It is slower due to error checking and acknowledgment, but ideal for web browsing, emails, and file transfers.

#UDP stands for User Datagram Protocol, which is a connectionless protocol that sends data quickly without guaranteeing delivery, making it suitable for streaming, online gaming, and voice calls.

Балансировка и проксирование L4-трафика в Angie

Возможности Angie в качестве веб‑сервера и обратного прокси довольно известны. Но кроме работы на уровне L7 (HTTP), мы можем применять его на L4 (TCP и UDP) в качестве балансировщика и прокси‑сервера. Именно об этой функциональности мы и поговорим в сегодняшней статье.

🚀 #HTTP3 is here to save us from the torturous ordeal of HTTP2, with a dash of #QUIC magic and a sprinkle of #UDP pixie dust. 🧚‍♂️ Just in case you missed the memo: faster handshakes and reliable streams will make your web experience *marginally* better, assuming you actually understand any of this. 🙄

Новый транспортный протокол? JPP — Just Packet Protocol

Небольшая статья-описание для идеи нового сетевого протокола транспортного уровня, который будет сочетать в себе некоторые плюсы уже имеющихся и, конечно же, будет оригинальным. JPP — Just Packet Protocol.

[Перевод] QUIC наконец-то приходит в Node.js: не прошло и 5 лет

Команда JavaScript for Devs подготовила перевод статьи о долгом пути протокола QUIC в Node.js. Четыре года сообщество ждало, пока OpenSSL откроет нужные API — и вот, с выходом версии 3.5, это наконец случилось. Уже в Node.js 25 ожидается первая реализация QUIC — шаг, к которому проект шёл почти полдесятилетия.

"This series is the result of careful analysis of UDP stack, to optimize the receive side, especially when under one or several UDP sockets are receiving a DDOS attack.

"I have measured a 47 % increase of throughput when using IPv6 UDP packets with 120 bytes of payload, under DDOS."

AKSHUALLY, YOU ARE CHEATING!

No seriously, the idea of #MultiLinkPPP isn't new and in #EDGEland aka. #Germany there a company to this day called #Viprinet who's CEO & Founder actually patented both mixed-technology link bonding and transparent applianced devices to facilitate these links, allowing for transparent redundancy, bonding, speed and low latency, without packet drops and on-the-fly speed changes.

And unlike #MultipathTCP and #PPP - #MultiLink setups or #MPLS it's actually an encrypted #VPN and can transparently allow all #IPv4 & #IPv6 packets through it - including #UDP - whilst not requiring cooperation from the #ISPs and being able to arbitrarily connect anything from ISDN to Cable and from 2G to 5G as well as Ethernet and WiFi...

The main selling point is that it reduces costs compared to #SDSL with guaranteed SLAs, so a link failing would merely slow down the speeds transparently.
