Switched Internets
The Move Toward Switched Networks
- All-switched LANs with stations connected to switches are still too expensive for most firms. Need a port for each station.
- Using switches as internetting devices is cost-effective today. Only hubs connect to switches. Only need a port for each hub
- As switching costs fall, companies can later move switching down to individual LANs by replacing hubs by switches. See CISCO white paper for details.
