VLAN
A virtual LAN, commonly known as a vLAN or as a VLAN, is a logically-independent network. Several VLANs can co-exist on a single physical switch.
A VLAN consists of a network of computers that behave as if connected to the same wire - even though they may actually physically connect to different segments of a LAN. Network administrators configure VLANs through software rather than hardware, which makes them extremely flexible. One of the biggest advantages of VLANs emerges when physically moving a computer to another location: it can stay on the same VLAN without the need for any hardware reconfiguration./p>

NetScreen-204/208
The Juniper Networks NetScreen-200 series includes two enterprise network products: the NetScreen-204 appliance with four 10/100 interfaces, and the NetScreen-208 appliance with eight 10/100 interfaces. Together, they are among the most versatile security appliances available today, easily integrating into many different environments, including medium to large enterprise networks, offices, e-business sites, data centers, and carrier infrastructures. Complete with either four or eight auto-sensing 10/100 Base-T Ethernet ports, the NetScreen-200 series performs firewall functions at wire speed (375 Mbps). Even the most computationally intense applications, such as 3DES and AES encryption, are performed at speeds up to 175 Mbps. In addition to physical interface density, the NetScreen-200 series optionally supports virtualization, including VLAN support and additional custom security zones and virtual routers.
