I am working on a paper on router, but one problem blocked my process. That
is what's the differents between a switch and a router for the view of

As to the 3 Layer switch and router, both of them work as a distributor
based on the IP address. Just some small differents usage and implemention.
Of coourse, we disscuss this problem on the switch and router on the same
layer.
A router decrements the IP TTL field.
It should also not propagate broadcast IP packets (subnet or all 1's).
(Any other hard requirements?)
