[Dime] draft-ietf-dime-erp-01

[Sebastien Decugis <sdecugis at nict.go.jp>]

Hello all,

A new version of Diameter ERP document has just been submitted. It
should appear soon in the draft repository [1].

The main changes from the previous version are:

- We define a new Diameter Application for ERP (as decided during last
IETF meeting). This allows the routing of Diameter messages containing
ERP payload to the appropriate realm and server, and permits more
flexibility in the deployment of ERP : with the previous design from
version -00, the ER server had to be  collocated with the EAP server
(note: it was not written clearly in the document, but it was the only
working situation), which might result in some deployment and
scalability issues. This change has a profound impact on the way
Diameter ERP works, and explains why so much content has changed in the
document.

- The format of the newly defined AVP has also changed: we now define
two grouped AVP to transport the key request and key material. Grouped
AVP allow a more efficient parsing of the message, and keeps the
correlation of related information such as key name, key lifetime...

- A section "Open Issues" has been added. It lists the major design
challenges remaining on Diameter ERP, to be completed and addressed...

Thank you,
Best regards,
Sebastien.
