LAN switching (1)
LAN switches (developed in 1990)
- available for Ethernet, token ring, FDDI
- provide much higher port density at a lower cost than traditional bridge
- similar to transparent bridges: learning topology, forwarding, filtering
- LAN switch is called "frame switch", ATM switch is called "cell switch”
- micro-segmentation - fewer users per segment; collisions do not occur when one user per segment (dedicated bandwidth for a user)
