This app contains an ns-3 module extension for QUIC, a recently proposed transport protocol which runs on top of UDP, currently being standardized by the IETF.

This version is aligned with version 13 of the IETF QUIC drafts. Our implementation is based on the design of the ns-3 TCP implementation, and heavily extends it to account for the novelties of QUIC, such as:

• improved acknowledgement mechanism with respect to TCP
• multiplexing of different streams in a single connection
• 0-RTT handshake
• BBR
• custom stream schedulers

This version does not implement the TLS encryption of the QUIC packets, but simulates the exchange of the parameters relevant to its setup.

For additional details and a description of the main functionalities of the module please refer to and cite the following paper, available on arXiv:

Future work

Future extensions will update the module with the latest features when QUIC will become an IETF standard.
