Problems with Home GWs

High-cost and Subscriber-unaware

BNG

PROBLEM 1

• Difficult to

• launch new services

• maintain a

homogeneous

installed base

THE CHALLENGE

• In Fixed access, the

CPE has many

functions

• NAT

• Routing

• Firewall

BNG

PROBLEM 2

• All devices appear

behind the same public

IP address

• Can’t personalize

services
