SoNIC [1], a Software-defined Network Interface Card, which provides the access to the physical layer and data link layers in software by implement- ing them in software, provides complete control over network in real time; Hence it gives system programmers unprecedented precision for network measurements and researches. However, SoNIC only supports UDP transmission protocol for now. In this paper, we present the implementation of TCP over SoNIC and evaluation of TCP through- put over different configurations.
