Cleaning Up the Dirt of the Nineties - How New Protocols are Modernizing the WebSteffen Gebert
This document summarizes recent developments in web protocols, including HTTP/2, QUIC, and Multipath TCP (MPTCP). HTTP/2 modernized HTTP by introducing binary framing, multiplexing, header compression and server push. QUIC aims to replace TCP with UDP to reduce latency during connection setup. MPTCP leverages multiple network paths simultaneously for increased throughput and resilience.
The document discusses HTTP and web architectures. It begins with introductions from Nicolas Martignole and Quentin Adam. It then provides an overview of HTTP1 including that it is a text-based specification, uses simple requests and responses over TCP connections, and defines verbs like GET, POST, PUT, and DELETE. It discusses techniques for caching like Expires, Pragma, and Cache-Control headers. It also covers ETags for cache validation and content negotiation for serving multiple representations of resources.
The document discusses the SPDY and QUIC protocols which aim to improve upon HTTP. SPDY focuses on multiplexing, prioritization, header compression, and server push/hints. QUIC aims to eliminate head-of-line blocking, support 0RTT connections, recover lost packets, and survive network changes. Both protocols aim to improve web performance but also face security challenges around things like certificate revocation and content inspection. The future may see both protocols widely adopted in web clients, servers, and network infrastructure.
A new Internet? Intro to HTTP/2, QUIC, DoH and DNS over QUICAPNIC
The document discusses recent changes to internet protocols that are aimed at improving performance and security. It describes the evolution from HTTP/1.1 to HTTP/2, which introduced features like multiplexing and header compression. It also covers the development of QUIC and DOH - UDP-based protocols that can enhance performance by avoiding head-of-line blocking and enable new use cases. QUIC is being deployed to carry HTTP and DNS traffic, while DOH standardizes encoding of DNS queries over HTTPS to prevent discrimination of DNS resolution. These protocol changes are driving more internet traffic to use HTTP, HTTPS and soon DNS over secure and optimized transports.
200, 404, 302. Is it a lock combination? A phone number? No, they're HTTP status codes! As we develop Web applications, we encounter these status codes and others, and often we make decisions about which ones to return without giving much thought to their meaning or context. It's time to take a deeper look at HTTP. Knowing the methods, headers, and status codes, what they mean, and how to use them can help you develop richer Internet applications. Join Ben Ramsey as he takes you on a journey through RFC 2616 to discover some of the gems of HTTP.
HTTPie is a command line HTTP client that aims to make interacting with web services as human-friendly as possible.

File Transfer Protocol (FTP) was established in 1971 and allows users to transfer files between computers over a network connection. FTP uses TCP/IP to transfer files in either ASCII or binary format for large files like music, videos, and software. An FTP server, either public or private, is required to facilitate the transfer and can be a dedicated server or a computer running FTP server software. While convenient for file sharing, FTP transfers are not encrypted or secure.
Peer-to-peer networks are right solution for distributing mostly static content to multiple clients while exploiting bandwidth of all clients to share file chunks and available bandwidth.
Torrent is currently most used P2P network protocol, but in this day and age it suffers from lack of official specification and has stigma attached to it. However, if you want to distribute software updates or create multiple disaster recovery sites it makes sense to create private torrent network which will to it's job.
In this presentation I will try to explain what it takes to create your own peer-to-peer cloud based on torrent protocol.

This document discusses a proof-of-concept for live streaming of video and subtitles within a browser. It uses HTTP Live Streaming to segment video into MP4 files and subtitles into WebVTT text files. A JavaScript player fetches and synchronizes the segments, displaying video using HTML5 video and subtitles via HTML track elements. While functional, the demo has limitations around rendering performance with dense subtitles, lack of seeking support, and HTML5 constraints on cue loading.
WebSockets allow for bidirectional communication between a client and server over a single TCP connection. They improve on older "Comet" techniques which used polling and long-polling to simulate real-time updates. With WebSockets, the client can open a WebSocket connection to the server which sends messages at any time without needing an explicit request. This enables real-time applications with constantly updating information. The document outlines the WebSocket protocol, provides examples of the API in browsers, and discusses frameworks for building WebSocket applications.

HTTP2 in action - Piet Van Dongen - Codemotion Amsterdam 2017Codemotion
We've all heard about HTTP/2, but what's in it for us? Is it really that much better? How can we start using it? During this talk, we will explore HTTP/2's new features while creating our own web server, demonstrating new features like server push, multiplexing and header compression. At then end, we can proof how HTTP/2 benefits not only the end user, but developers and operations as well!.
As a follow-up of the previous session about TFB, we will discuss what kind of tuning was made to the mORMot library, and its associated TFB sample implementation, to reach the top scores in charts. How can a pure Pascal project reach 7 millions of HTTP requests per seconds? How to scale and measure on high-end hardware? Are ORM frameworks damned to slow down everything? How to circumvent the lack of “async” programming at language level? How realistic is such a benchmark?
Slides for the talk I made at the virtual edition of FOSDEM 2022, on how to use WHIP for WebRTC broadcasting ingestion, and how the distribution process could be done via WebRTC as well, e.g., via Janus (and the SOLEIL architecture).
This document introduces txtWeb, a platform that allows anyone to create simple mobile applications and websites accessible via SMS without an internet connection. It aims to make digital content and services available to the billions of mobile phone users who lack internet access. Developers can build "txtApps" and "txtSites" through a simple API that handles the SMS-HTTP translation. The platform handles session management and allows for menus, user input, and push notifications. Over 250 organizations have already built applications on txtWeb to provide information to users in areas like agriculture, transportation, and entertainment. The document provides examples of existing txtApps and explains how to build applications and implement push notifications through the txtWeb API.

Accident detection system project report.pdfKamal Acharya
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.
