Juniper JUNOSE SOFTWARE 11.2.X - BROADBAND ACCESS CONFIGURATION GUIDE 7-20-2010 Configuration Manual page 131

The information exchange between the PDP and PEP consists of data that is modeled
in Policy Information Bases (PIBs) and is encoded using the standard ASN.1 basic encoding
rules (BERs).
JunosE Software uses the following PIBs:
Proprietary PIB
JunosE-IP-PIB—This PIB defines the data model for manipulating IP service policies
and addresses offered through DHCP in JunosE Software.
Non-proprietary PIBs
COPS-PR-SPPI
COPS-PR-SPPI-TC
DIFFSERV-PIB
FRAMEWORK-FEEDBACK-PIB
FRAMEWORK-PIB
FRAMEWORK-TC-PIB
The COPS-PR support in JunosE Software uses the proprietary PIB. This PIB consists of
a series of tables that is supported in previous JunosE Software releases, including the
proprietary accounting and address assignment mechanisms.
You can force the router to restart a COPS connection to, and resynchronize with, a PDP,
without disabling the SRC client's COPS support. The SRC software and the SRC client
maintain common state information in PIBs that both the SRC software and the SRC
client use. Previously, you disabled the SRC client and reenabled it to start synchronization.
The disabling of the SRC client's COPS support was undesirable for the applications that
required resynchronization in addition to maintaining the COPS support. If the state of
the SRC software is not synchronized with the router, the SRC software may be required
to initiate resynchronization from the router.
The proprietary PIB provides the Policy Manager and QoS Manager functionality shown
in the following lists.
Policy Manager
Committed access rate
Packet filtering
Policy routing
QoS classification and marking
Rate limiting
Traffic class
QoS Manager
