To get you started, many have tried to understand this assignment this week.
There are suggestions this closed thread.

I'm not clear whether your solution is allowed to use the "dd" command or not?
The "dd" command is unusual in unix because it uses the syntax "switch=value" rather than the more usual "-switch value" or the Linux "--switch=value".


Tip: I'd avoid calling a script "test". It is the name of a unix command.

uml_switch

UML_SWITCH(1)						      General Commands Manual						     UML_SWITCH(1)

NAME

       uml_switch -- switch daemon for user-mode Linux

SYNOPSIS

       uml_switch [-unix control_socket data_socket]  [-hub]  [-tap tun device]  [-compat-v0]  [-daemon]

DESCRIPTION

       This manual page documents briefly the uml_switch program.

       This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

       uml_switch is a daemon for managing a virtual network between user-mode Linux systems, with no connection to the host system's network.

       It will listen for connections on a pair of UNIX domain sockets, and forward packets between clients which connect to them.

OPTIONS

       -unix control_socket data_socket
		 Listen on the specified pair of sockets, instead of the defaults.

       -hub	 Act  like  a hub.  This means that packets received will be broadcast over all virtual links.	The default is to act as a switch,
		 where packets are only sent to the link matching the destination MAC address of the packet.

       -tap tap device
		 Connect the switch to a dynamically created tap device on the host

       -compat-v0
		 Specify control protocol version 0 compatibility.

       -daemon	 Run in the background as a daemon.
