In standard environments, both Data Link and the Physical (PHY) layers are defined in the Network Interface Cards (NIC) and they cannot be accessed in real-time via software. However, these lower layers contain valuable information that can be used to measure and to improve the performance of the network. Recently, SoNIC was proposed to provide real-time access to the Physical Layer and it was used to accurately measure the performance of a high-speed wired complex network. Current SoNIC design and implementation only operates in 10 GbE (Gigabit Ethernet) devices. In this project, we present a SoNIC design for 1GbE devices as an effort to extend the SoNIC ecosystem.
