VLAN Parameter
Generally, Internet provides only Best Effort Service. Since Ethernet is the most spread LAN
access technology, importance of providing it a quality of service mechanism ought not to be
neglected.
Ethernet technology also used as WAN technology, not only as LAN technology. Due to rapidly
increasing use Internet through Public Switched Telecommunication Network (PSTN), Telephone
Companies are forced to implement IP-based networks as their PSTN backbones. A network like
this without any Quality of Service mechanisms would be disastrous. Just imagine yourself trying
to get an emergency call through while others just surf the Internet.
