Traditional Problems 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

• 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
