Have a title, provide switch each port to the server MAC address, and show port is linked, to various sort out switch port connection object, such as
Switch port information is as follows:



The graph is: the relationship between switches and server


Switch the port connection object:
Switch 1
Port 1: switch 2; Switch 3 port 2:
Switch 2
Port 1: server 1; Port 2: the server 2; Port 3: switch 1
Switch 3
Port 1: the server 3; Port 2: switch 1

You think what kind of algorithm is better, if you can post implementation code to discuss with us
