Networks are Essential!Networks are Essential! Networking is an integral part of computer systems The role of a network interface is evolving

Significant new research is changing the hardware/software interface between the operating system and the network interface card (NIC)

Researchers need a flexible NIC to study this field RiceNIC is a reconfigurable and programmable Gigabit

Ethernet NIC that meets these research needs NIC design is freely available for research/education! NIC provides significant computation and storage

resources and allows the user to customize NIC behavior in software and hardware.
