Performance measurements of QUIC communications

Performance measurement in terms of packet loss, delay, and jitter is key in modern packet switched networks. These values give a clear indication of the quality of service (QoS) perceived by users, thus being helpful to service providers to properly support, in particular, real-time communications such as voice and video conferences. This paper addresses these issues in QUIC-based communications, introducing a novel performance measurement methodology and comparing it with existing proposals in this field. The new solution for delay measurement uses only one more bit in addition to the Spin Bit, rather than the two additional bits required by the Valid Edge Counter (VEC) solution. Despite this, it is equally effective in overcoming the limitations of the Spin Bit solution and it performs similarly to the VEC solution. These results are shown by means of an experimental validation and evaluation on a proper testing environment.
