Discussion on HTTP over UDP techs with UDT or QUIC or KCP

[sequoiar]

HTTP over UDT over UDP was implemented. And, welcome discussion on HTTP over UDP tech with UDT, QUIC and KCP.

Hey there,

Could you help me find the implementation for UDT in this repo?

[amiiigh]

Or like which part of the code do I need to use only UDT in my nodejs code?

[sequoiar]

UDT api is like Net module api, while UDTS api is like TLS api. check below link for detail
https://github.com/InstantWebP2P/nodejs-httpp/wiki/An-introduction-to-run-http-over-udp-with-node.js
The HTTPP to HTTP modules mapping is like below: net -> udt, http -> httpp, tls -> udts, https -> httpps.

@sequoiar the first line
var udt = require('udt');
imports udt. my question is where is the implementation of this library?

[sequoiar]

@amiiigh
check https://github.com/instantwebp2p/uvudt/tree/8d4f021d8042a82988472a9db43382fa28190d9d
UDT is an extension to libuv as uvudt

Does HTTPP use the packet/stream mode of UDT or message mode?
Where can I find the parts of the code when HTTPP uses sending/receiving calls of UDT?
Thanks

[sequoiar]

@NooshinEghbal HTTPP(http) is run UDT stream mode. if you want message mode, you can implement nodejs/diagram over UDT message mode.

[NooshinEghbal]

I looked into the wiki page and the HTTPP server/client example.
So, if I have a group of resources (e.g. font, image, css and JavaScript files) for a web page, how can I use HTTPP to measure the page load time?
And also how can I change the underlying protocol from UDT to KCP for HTTPP?

[sequoiar]

@NooshinEghbal there is no httpp enabled web-browser so far. not sure httpp.client can help on it.

[NooshinEghbal]

What if I just want to send a group of files from httpp server to the client?

[sequoiar]

@NooshinEghbal you can try httpp.get a file from httpp.server . you need assemble some basic HTTP message.
