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
