The Split

  • draft-ietf-radext-ieee802-01 split into three documents

    • draft-ietf-radext-vlan-00 : Bernard Aboba lead editor

    • draft-ietf-radext-filter-rules-00 : Mauricio Sanchez lead editor

    • draft-ietf-radext-redirection-00 : editor TBA

  • Why?

    • Contentious filtering attributes impeded progress of entire document

  • Split allows staging of attribute delivery

    • draft-ietf-radext-vlan-00 completed WGLC last week

    • draft-ietf-radext-fiter-00 no later than Oct. 2006

    • draft-ietf-radext-redirection no later than Dec. 2006

TBD

Likely just guidelines for NAS-Traffic-Rule


“filter” draft issues and work items

  • Renamed NAS-Filter-Rule attribute to NAS-Traffic-Rule to avoid immediate confusion with Diameter’s version

  • Closure of number of issues

    • I102 : NAS/QOS-Filter-Rule

    • I109 : HTTP NAS-Filter-Rule assumes port 80

    • I110 : Compliance and Coherence

    • I112 : NAS-Filter-Rule

    • I116 : Technical Comments

    • I129 : Editorial NITS

  • Pending (Filter-01)

    • I167 : Compatibility with RFC2866 and RFC3576

    • I168 : Editorial Comments


“filter” draft open issues

  • I111 – Accounting (Greg W.)

    • Proposal to remove suspect wording sent to email list

  • I114 – NAS-Filter-Rule Accounting (Bernard A.)

    • Use case sent to email list

    • Discussed at IETF64

  • I115 – NITs (Dave N.)

    • Mostly closed; There is dependency on I114 for one

  • I130 – Diameter Interoperability (Bernard A.)

  • I164 – Review (Jari A.)

    • Misc. NITS; mostly closed except for Diameter issue (as I130)

  • I169 – Handling unparseable rules (Greg W.)

  • I170 – Precedence and Order for NAS-Filter-Rule (Greg W.)


I130 – Diameter Compatibility

  • At IETF 64 tenuous consensus was to:

    a. Not split-up attribute into multiple attribute

    b. Use existing practices to allow Diameter to inherit RADIUS NAS-Filter-Rule attribute

    c. Rename attribute to avoid confusion

  • Consensus fell apart on point B

    • “Diameter community should get their say on rule syntax”

    • “We shouldn’t have two related yet non-compatible attributes”

  • New proposal: Radius/Diameter Lockstep

    • DIME WG exposed to current rule syntax and given opportunity to speak up; No one thus far

    • RADEXT WG completes attribute with DIME WG formal blessing of syntax

    • DIME WG updates Diameter with *same* syntax from RADIUS
