Cisco Systems has rolled out two new products designed to help enterprises increase their network capacity without overhauling their existing infrastructure.
The networking vendor's new line of switches--the Catalyst 6500 Series VSS (virtual switching system) 1440--is paired with a software engine that enables the "virtualization" of the switching hardware (http://www.news.com/Virtualization-A-feature-of-the-hardware%2C-not-the-OS/2100-7339_3-6206867.html), by combining multiple switches to act as one node on the network.
According to Cisco, combining the switches multiplies the bandwidth on the network--which can reach 1.44Tbps (terabits per second)--because those that are virtualized are seen as a single node with one IP address. The management of multiple switches is also simplified. ...

In theory. Lets say you have a 3 tiered network like I do
Internet ......|
A--------------- Main Switch
| \_____
B-------Upstairs Switch - Downstairs Switch
/|\ /|\
C-- X, Y, Z (class switch) z,Y,x

Basically for me, the Individual classrooms can talk to each other without going to Main or class B switch (with this technology), however if they want any Internet packets they have to talk to main switch.
