Traditional Problems Expensive implementation based on E1x/SDH/ATM Infrastructure not fit new applications in flexible way Complicated provision –Deep involvement in customer's site –Complicated configurations in SDH-MUX and CPE –Modules upgrade in CPE or entire unit for high bandwidth –ISP POP significant changes Facing bandwidth allocation problems Expensive costs from customer to application Ethernet LAN Router CSU/DSU SDH SDH Ethernet LAN Router CSU/DSU ATM/MUX

What solution desirable ? Simple network composition Simple network composition IP - IP application favor IP aware Network Bandwidth - Bandwidth provision from Access to Core Management - Management for entire infrastructure by ProVision application Maximum service over long distance Maximum service over long distance - Through optical Fiber to Telephone lines (VDSL) High-Efficiency and Cost-Effectiveness High-Efficiency and Cost-Effectiveness - Extracts full performance from existing infrastructure - Network with low investment, compared with any other solutions

Metro Ethernet Solution Ethernet circuit technology

Element solution provide: Flexibility – Modularity Bandwidth provision - Rate limit - Classification - Quality of service Any fiber connectivity - Fiber up to 150km - Diverse fiber connections SC,MTRJ,VF45,ST,LC - CWDM/DWDM for pure optical core - Complementary to Fiber - VDSL solution Security VPN Data

Ethernet Circuit Circuit like parameters per Flow (SLA) –Granular bandwidth –Defined Class of Service –Electrical signal based security (VLAN and MPLS) –Layer 2 VPN End to end solution –Same Ethernet from NIC to NIC –Tag/Label concept (like ATM header)

Ethernet Circuit keys Traffic shaping –Rate limiting Per Flow –Prioritized forwarding Security - Access Intrusion Control Qos/Cos - Differentiated services Advanced billing mechanisms - Per flow accounting Centralized management - MegaVision™,Provision™
