A quick news!
ACM students research competition in SOSP'19, Toronto, Canada
What is QUIC?
Research interest:
0-RTT connection setup
Low Latency
Head of line blocking
Within the scope of this thesis!
QUIC TLS API for crypto in gnuTLS
Custom QUIC version integration in VLC for better streaming experience.
Work update: Mini Project!
Exposing QUIC TLS APIs in gnuTLS
- A callback to notify the key (epoch) change
- A callback to write a Handshake messsage, when it is being sent
- A callback to write an Alert messasge, when it is being sent
- A callback to flush the message.
- A function to push data received from the peer to the TLS layer
Initial QUIC setup
ngtcp2 + ngHTTP3
Work update: Mini Project!
Updates after Mini Project
1) quicsy: A HTTP3/QUIC tool devised.
It does HTTP/3 request-response pair.
2) Segmentation: segments and manifest created for a mp4 file. Scripts to do encoding/segmentation were written
3) Host the segments in a web server
4) Mininet script to emulate a topology for controlled network experiments
5) Work in progress: HTTP/3 and QUIC implementation in VLC
1) Quicy: A HTTP3 tool
- Based on ngtcp2 + nghttp3
- A stand-alone network module
- Can send and recieve any size of data
Demo!
2) Segmentation: Flow
2) Segmentation: HLS Streaming
2) Segmentation: DASH Streaming
2) Segmentation: Process
Demo!
3) Host the segments in a web server
ABR streaming test with VLC
Bug in VLC found, frames being dropped.

By the next review:
Complete Mininet scripts
Evaluation of existing ABR over HTTP/1.1 and HTTP/2 in VLC
Simple live streaming over HTTP application using any ffmpeg or libav library to test our quicsy tool
Wrap up the VLC implmentation of HTTP/3 and QUIC.
Live streaming over HTTP application using any ffmpeg or libav library to test our quicsy tool
Finally, What's proposed...?
In Custom QUIC extension (QUIC-tweaked) ....?
-
Selective Reliable Transport
-
Deadline Awareness
-
Message-Oriented Abstraction
-
Forward Error Correction
-
I-P-B frame handling
-
Head-Of-Line blocking resilience
