Improving network security through port switching
Bill Hancock · Network Security · 1998
The latest range of network performance improvement is the use of switching technologies to isolate traffic from various systems. This is achieved by placing a system on a device called a switching bridge which, in turn, isolates traffic by only allowing packets to be sent to the port on which the system is located when a packet is actually addressed to the system in question or when the message is a group or broadcast message that would be sent to all nodes. In a typical LAN environment, systems on a network segment ‘see’.
