 draft-ietf-soc-overload-control  says
" 8.  Syntax

   This specification extends the existing definition of the Via header
   field parameters of [RFC3261] as follows:

       via-params  =  via-ttl / via-maddr
                      / via-received / via-branch
                      / oc / oc-validity
                      / oc-seq / oc-algo / via-extension


       oc          = "oc" [EQUAL oc-num]
       oc-num      = 1*DIGIT
       oc-validity = "oc-validity" [EQUAL delta-ms]
       oc-seq      = "oc-seq" EQUAL 1*12DIGIT "." 1*5DIGIT
       oc-algo     = "oc-algo" EQUAL DQUOTE algo-list *(COMMA algo-list)
                     DQUOTE
       algo-list   = "loss" / *(other-algo)
       other-algo  = %x41-5A / %x61-7A / %x30-39
       delta-ms    = 1*DIGIT"
and
"11.  IANA Considerations

   This specification defines four new Via header parameters as detailed
   below in the "Header Field Parameter and Parameter Values" sub-
   registry as per the registry created by [RFC3968].  The required
   information is:

       Header Field  Parameter Name  Predefined Values  Reference
       __________________________________________________________
       Via           oc                 Yes             RFCXXXX
       Via           oc-validity        Yes             RFCXXXX
       Via           oc-seq             Yes             RFCXXXX
       Via           oc-algo            Yes             RFCXXXX

       RFC XXXX [NOTE TO RFC-EDITOR: Please replace with final RFC
       number of this specification.]"

The text of draft-ietf-soc-overload-control refers to both "loss" and 
"rate"  as values for  oc-algo.

The text of draft-ietf-soc-overload-control  section 5.3 refers to the use 
of oc for either rate or loss

"As an example, a value of "oc=10" when the loss-based algorithm is
   used implies that 10% of the total number of SIP requests (dialog
   forming as well as in-dialogue) are subject to reduction at the
   client.  Analogously, a value of "oc=10" when the rate-based
   algorithm [I-D.ietf-soc-overload-rate-control] is used indicates that
   the client should send SIP requests at a rate of 10 SIP requests or
   fewer per second."

What are you suggesting would go in the "IANA Considerations" section of  
draft-ietf-soc-overload-rate-control ?  Does it just need a reference to 
the IANA Considerations in draft-ietf-soc-overload-control?

Hi,

registers the new Via header field parameters.

>Is it needed here as well? 
 
The draft (Section 5) does extend the oc parameter, doesn’t it? I would 
assume that needs to go to IANA.
