SUMMARY
An IP VPN is a virtual private network used to deliver
IP services
implemented over an IP provider network. This document
defines the
requirements for a policy information model for provisioning
IP
VPNs. It identifies the network level capabilities that
need to be
represented in the policy information model.

WHERE DOES IT FIT IN THE PICTURE OF THE SUB-IP WORK
PPVPN - Provider Provisioned VPN
WHY IS IT TARGETED AT THIS WG
From the charter :
"Particular attention will be placed on SP requirements
for security, privacy, scalability and manageability
considering such factors as Service Provider's projections
for number, complexity, and rate of change of
customer VPNs over the next several years."
A significant portion of the managebility requirements
should be cordinated with, or addressed by the
management solution. The provisioning component
of the management solution needs to adopt a commonly
agreed upon schema for capturing VPN requirements
on the network. This schema can be defined in
the form of an information model, which can later
on be implemented over SNMP or LDAP or any
other deployment choice.
JUSTIFICATION
-----------------
| Service Level | --> SLS capture customer requirement/service
goals
-----------------
<>--------->
Service goal to network policy translation
-----------------
| Network Level | --> IP VPN policies capture network
requirements
-----------------
<>--------->
Network policy to devices level specifications
-----------------
| Device Level | --> Device specific configuration
-----------------
There is a need to capture the network requirements
to meet the service goals.
These requirements can them be communicated to the
network using an IPVPN information model
