CSCum67660 - Configurable dictionaries on Diameter interfaces
Applicable Products: ePDG, GGSN, HA, HSGW, IPSG, MME, PDSN, P-GW, SGSN, S-GW
Feature Changes
Dynamically Configurable Dictionaries on Diameter Interfaces
Diameter dictionaries need frequent customization primarily due to the difference in the interpretation of the standards
and any new customized features as required. As the Diameter dictionaries are statically defined for each interface and
for each operator separately, the turn around time to customize these dictionaries is high. Hence, a new Dynamic
Dictionary framework has been introduced. This will facilitate creation of a new Diameter dictionary in ABNF encoding
format which is a readable text file and loading it to the chassis using a new CLI. Then, apply this dictionary to any
application which talks to external Diameter servers such as PCRF, OCS and AAA servers. Dynamic dictionary support
also exists for all Diameter - AAA interfaces. MME/SGSN - HSS Diameter interfaces like S6a and S6d are not
supported in this release.

Important:
It is highly necessary that you must not create dynamic dictionary for your customization needs.
Contact your Cisco account representative for any new dynamic dictionary creation request.
It has been confirmed that the Diameter dictionaries can be dynamically configured on various Diameter interfaces like
Gx, Gy, etc.

CSCum69764 - CCR-u & CCR-f routing enhancement for Customer RDR
Applicable Products: GGSN, P-GW
Feature Changes
CCR Routing Enhancement
In a scenario where a PCEF is connected to OCS via multiple Diameter proxies, PCEF chooses the same Diameter
proxy for the subsequent messages as long as it is available.
proxy for the subsequent messages as long as it is available.
Any subsequent messages (CCR-U/CCR-T) to the same host are sent via the same peer. Once the next-hop is chosen via
round-robin method, the subsequent message for the session is sent to the same next-hop (peer).
