Virtual Developer Workshop: Containerized Development with Docker
The Linux Soft Switch allows a computer to work as a switch on layer 2. It is designed to switch packets based on MAC addresses and forward them to the proper outgoing network interface(s).
Note: With this version (1.0), Soft Switch can support up to four hosts connected to the Linux Soft Switch host. It means that the Soft Switch host has at least two NICs and the max is four NICs.
