[j-nsp] Broadband Model suggestion?

[Frank Norman]

Dear friends,

I need suggestion for broadband network based on xDSL & fiber based last
miles (GPON/Metro technologies), Subscriber base upto 40-50 thousand
customer,

Requirement for subscribers will be;
- Authentication & authorization
- Dynamic Rate-limiting policing (with Multi service support)
- Session state monitoring
- Session Accounting for Billing (prepaid/postpaid)

and other policies in standard broadband networks.


Now can someone tell me

1) what are the standard models (PPPoE or DHCP ? ) that are being used in
such kind of broadband networks?? and which is more flexible??

2) How is bandwidth management for subscribers is handled?? through the
same BRAS or by installation of separate devices like packeteer,
packetlogic etc

2) Which devices/vendors can handle these kind of requirements??  (We
already have AAA radius expertise, so i am only concerned with network
equipment side)



Good Day!

Frank
