A Behavioral Study of TCP Linux Variants over Satellite Networks

The Transmission Control Protocol (TCP) is used by the vast majority of Internet applications. Since its introduction in the 70s, a lot of variants have been proposed to cope with the different network conditions we can have (e.g., wired networks, wireless networks, satellite links) and nowadays Linux OS includes 13 different TCP variants. The aim of this paper is to offer a detailed comparative analysis of the behavior offered by these variants over satellite networks, in terms of congestion window behavior and achieved throughput.
