5 Market situation Increased Remote Access Means 5

6 What is Broadband Aggregation? roadband aggregation is the glue that dynamically binds the subscriber to evenue generating services. Broadband Aggregation rides above varying ccess methods such as ISDN, DSL, Cable, Metro, FTTX and Wireless last mile ptions. Revenue Generating Services (Video, Gamming, Movies ) Subscriber Aggregation (Authentication and Accounting ) Subscriber Access (Dial, DSL, Cable, Metro, ETTX Wireless ) 6

7 Broadband Aggregating Dynamic Policy across any medium Access Features VLAN, VPN ACL QoS Tiered Bandwidth Services Applications Interoperation Identity Subscriber Authorization Authorization & Provisioning Provisioning Dynamic Policy Accounting Accounting Key to ownership Application to Network Authentication Single Sign On Device Identity Revenue Billing Flat-Rate Post-paid Pre-paid By Service By Application 7
