If you used to play around with GNS3, you’ll find the term NIO. I always wondering what is the meaning of it. Finally I found it here.
NIO is stand for Network Input/Output
There are a few type of configurations in GNS Network Input/Output (NIO) which are:
- NIO Ethernet
- NIO UDP
- NIO TAP
- NIO NULL
