i386-libraries of libc and libcrypto are optional (Linux only), they are only needed to run IOU based nodes.

mtools is recommended to support data transfer to/from QEMU VMs using virtual disks.

Docker is optional (Linux only), some nodes are based on Docker.

libvirt is recommended (Linux only), as it's needed for the NAT cloud.

Qemu is strongly recommended on Linux, as most node types are based on Qemu, for example Cisco IOSv and Arista vEOS.

VPCS is recommended, it is a builtin node simulating a very simple computer to perform connectitivy tests using ping, traceroute etc.

Dynamips is required for running IOS routers (using real IOS images) as well as the internal switches and hubs.

uBridge is required, it interconnects the nodes.
