Network EvolutionNetwork Evolution
TDMFrame Relay ATM IP
In TDM network, the network’s bandwidth often lies idle.....
Frame Relay network can’t offer carrier voice quality .....
ATM is widely deployed, but complex and expensive …..
ZyXEL believes IP is the best way for the future

IP vs. ATMIP vs. ATM
IP
• QoS (802.1p, 802.1q)• High speed for backbone
(1Gbps, 10Gbps)• Low cost equipment• Better bandwidth
utilization • Ease of Use• Easy for Maintenance and
troubleshooting
ATM
• QoS (CBR, VBR, UBR)• High Speed for backbone
(155Mbps, 622Mbps)• Expensive ATM
equipments (30%-50% higher than IP equipments)
• 20-30% waste in bandwidth
• ATM network is complex
