QUIC is a new secure multiplexed transport protocol built on top of UDP. This general-purpose transport protocol aims to provide the lowest connection latency possible and solve the shortcomings of TCP, UDP, and current problems of the internet. Furthermore, it allows further development of the transport protocol without upgrading the network infrastructure. Last year in May 2021, QUIC was finally standardized by the IETF, allowing for full development and release while also opening the path for future research as older research dated due to using the older version and the finalization of QUIC standard protocol. While there are a lot of different QUIC implementations, this thesis selected two and conducted a performance evaluation on the cloud environment and compared the two while also taking the sustainability aspect into account. Asa result, we will find which of the selected implementation is environmentally friendly through this experiment while also providing good performance. / <p>2022 GENIAL Summer School</p>
