I would like recommendations on the following software/hardware elements re=
quired to run an access network. Assume you are building a greenfield netwo=
rk using a combination of access technologies such as DSL, GPON, AE, and Wi=
Fi.
IPAM / DDI Solution: Needs full support for IPv6, Customer VLANs, RFC 1918,=
VRF, Overlapping Address Space, integration with DNS, DNSSEC, Integration =
with DHCP, and integration with ARIN. Looks like there are both open source=
and commercial solutions available according to old NANOG posts. Which cat=
er to service providers? Who are the leaders in this space? Does anyone hav=
e experience with dealing with multiple vendors?
Subscriber Management/BRAS/BNG: Redback was the big player back in the day,=
but I believe they are no longer. Juniper has their Subscriber Management =
feature pack on their MX routers, and Cisco has their Broadband Network Gat=
eway on their ASR routers. Besides these two vendors I am not sure what oth=
er solutions are out there. I believe both of these solutions communicate u=
pstream to external radius servers and DHCP servers. Is anyone using Subscr=
iber Management, or is there another way of doing it?
CMDB: A centralized database to keep track of all assets within the network=
would be nice. I would assume this would need to tie in with the IPAM solu=
tion and billing systems.
I would also like to hear thoughts on the per customer VLAN model. Most of =
the whitepapers recommend a per customer VLAN for greenfield networks, but =
that seems like a management and documentation nightmare. The systems descr=
ibed above must be able to manage and maintain per customer VLANs in an aut=
omated fashion for this approach to work and scale.
If you had your choice starting from the ground up how would you deploy an =
access network today?
