# NuvoLink Network Card emulation
# SCSI Network Card emulation
The aim is to provide network capabilities through SCSI interface emulated by RaSCSI.
This documentation is for developer who would like to contribute to this project.

## How does it work?
Packets can come from `wlan0` or from localhost, they are sent to a tun/tap virtual interface named `ras0`.
The RaSCSI software connects to `ras0` and reads the packets, then write those packets to the SCSI interface.
On the Mac, the NuvoLink SC Driver, reads the packets from the SCSI physical port of the Mac and provide them to the System.
Same operation happen in the other direction when packets are sent from the Mac to the SCSI (thanks the NuvoLink SC Driver).
On the Mac, the device driver, reads the packets from the SCSI physical port of the Mac and provide them to the System.
Same operation happen in the other direction when packets are sent from the Mac to the SCSI (thanks the driver).
RaSCSI reads the packets from the SCSI emulation and write then to the virtual network interface `ras0`, packets can then travel to the internet through `wlan0`.
