Performance Evaluation of HTTP/3 as an Interservice Communication Mechanism

Abstract: The HTTP protocol is widely used for communication and data transfer on the internet. HTTP requests are sent from clients to servers, and the servers respond with the requested data. HTTP is not limited to web pages, but can be used for any service that provides resources when requested. The most recent version of HTTP, HTTP/3, uses a new transport protocol called QUIC, which provides increased performance by improving on the connection handshake and multiplexing processes. This paper aims to perform a performance analysis of HTTP/3 in an interservice communication system, focusing on latency and throughput. The research will compare HTTP/3 to HTTP/2, and also explore the practical implications of the performance analysis. To gain real-world insight, the study will partner with WirelessCar, an automotive software company that maintains high throughput services built on HTTP.
