Suffer from shared medium infrastructure
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

What solution desirable ?
• Simple network composition
- IP application favor IP aware Network
- Bandwidth provision from Access to Core
- Management for entire infrastructure by ProVision application
• Maximum service over long distance
- Through optical Fiber
to Telephone lines (VDSL)
• 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

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

Management
•Ethernet over VDSL Features:
– 12 Mbps symmetric Ethernet
– POTS/ISDN support
– Reach up to 4000ft/1200m
•Software selectable rate
•Software selectable ETSI 997/998
•Easy mix of FE or GbE interfaces
•Works with harsh Telco interference and noise models
Fiber
Rate Limit from Access to Core
• Rate limit per Ethernet Circuit
– By port
– By IP
– By TCP/UDP port
• Tens of Kilobit level increments
• Performed in the switch at the access level
Classification from Access to Core
• Class of service based on DiffServ protocol
• Priority marking based on ToS field
• Per Circuit Classification
– By port
– By IP
– By TCP/UDP port
Security from Access to Core
• IP Intrusion Control
– Port/MAC/IP Table look up for intrusion prevention
– Unauthorized user can not access the network without the proper parameters
• Management VLAN prevents access of the switch management through the
access port
• Layer-2 VPN with MPLS in the OSM IP Terminator
• End-to-end Ethernet circuit security scheme
