VLAN

VLAN stands for virtual LAN (Local Area Network), VLAN basically a logical networks within already existing physical network. VLAN creates the logical segment of a LAN into different broadcast domains and this broadcast domain can send or received data from any computer located within that network.

VLAN can be based on

• ports type
  


• protocol type
  


• MAC address
  


• and IP subnet address.
  

There are many reasons to use VLAN over traditional LAN.

Performance: VLAN used to reduce the need to send the traffic to unnecessary destination in a network.

Security: VLAN decreases the chances that people will gain access to data the are not authorized to see it.

Control Traffic Flow:VLAN does not broadcast traffic to nodes that are not part of that VLAN.

Wireless Protocol - WORP

WORP is a new protocol that is designed to optimize the performance of outdoor wireless point-to-point and point-to-multipoint links using 802.11b radios.

The use of 802.11b radios and bridges enables Proxim to offer a low cost, feature-rich solution that is ideal for economical last mile access and campus networking.

WORP takes care of the performance degradation that happens when standards-based 802.11b
wireless LAN technology is used for outdoor building-to-building connectivity, incurred by the socalled “hidden-node” problem.
