TCP and transport protocol performance
TCP is the most widely used transport protocol for applications. It is used for WWW, email, and file transfer. TCP was originally specified decades ago (RFC793(O) from Sep 1981, updated to RFC9293(S) in Aug 2022). In the intervening time, improvements in transmission speeds means that TCP needs to be modified to make best use of the available network capacity.
This work has considered the performance of TCP, including: when used with ILNP; the impact of buffering in the network; as well as the fairness of TCP and its variants when used together.
