Informational Presentation

Author: IPv4 Guideline Working Group

Introduction:
This proposal presents the conclusion made by IPv4 Guideline Working Group 
about modifying the 'APNIC Guidelines forIPv4 Allocation and Assignment Requests' 
to fit both Cable and DSL services.

Detail:
IPv4 Guideline Working Group was opened in August 2004 to review and develop 
modified guidelines for cable and DSL networks in the 'APNIC Guidelines for 
IPv4 Allocation and Assignment Requests' document based on the Informational 
Proposal, 'Subsequent Allocation Criteria for DSL and Cable Services', in 
APNIC 17. The main target is to modify the 10.2 section to fit both Cable 
and DSL services not only Cable. After several months discussing, we draft 
the following statements.

10.2	Criteria for subsequent allocations to Cable or DSL services

	Organisations seeking subsequent allocations to Cable and DSL
	services must provide the following information:
	
	* headend information specifying the number of CMTS or B-RAS
	  devices planned per headend;
	* the projected number of subscribers within 3 months;
	* growth rate based on average growth or IP utilisation per
	  month over past three months (as an option, the ISP can
	  supply a MRTG or RADIUS/DHCP server log(for example) to
	  support growth rate evaluation);
	* projected number of subscribers, DSL/Cable circuits
	  subscribed or IP addresses consumed by subscribers at peak
	  time within 12 months (if the projection is significantly
	  higher than that predicted by the growth rate or IP
	  utilisation, then an additional explanation will be
	  required); and
	* Purchase receipts for equipment (if requested by APNIC or
	  the NIR).

The major changes are as follow.
1. Add DSL service into the title and articles of this section. 
2. Add the B-RAS as the headend device to be considered in DSL service in item 1. 
3. Add the IP utilisation as an option to be considered on determining the past 
growth rate and add the RADIUS/DHCP log as an support information in item 3. 
4. Add the subscribed DSL/Cable circuits and consumed IP utilisation as options
of the projection in item4.

Besides, there were two suggestions not reaching the consensus: 
1. Suggestion from APNIC hostmasters denoted by Tim Jones to expand the projection 
period from "3 months" to "6 months" in item 2 as 
 
* the projected number of subscribers within 6 months

2. Suggestion from APNIC hostmasters denoted by Tim Jones to add some additional information which is asked to be provided by ISPs in current IP allocation applying procedure. The additional information has been modified from current version to fit both Cable and DSL services. 

	With regard to the address space you are seeking for your
	cable/ADSL service, please supply the information using the
	format provided.

	<example>

	Headend |Homes | Device |Capacity|Current|IP |Device|G-rate/
	         passed                    users       added  month
	------------------------------------------------------------
	Brisbane 15000  Motorola   1000     750   800    1    1254

	Where:

	Device - vendor, make/model and the quantity of CMTS/B-RAS
		 currently installed.
	Capacity - capacity of cable modem router per CMTS or ATU-R
		   per B-RAS. (Also provide number of users per
		   cable modem router or ATU-R.)
	IP - total number of IP addresses assigned to each CMTS/B-RAS.
	Device added - additional cable modem router or ATU-R that
		       will be deployed in 6 months time.
	G-rate/month - number of customers growth/month which have
		       joined your service since your last allocation.
	*Homes passed item could be empty for the DSL service

This Proposal is now submitted to APNIC OPM 19 Address Policy SIG as an Informational Proposal and posted into Address Policy SIG mailing List. Any comment and suggestion is welcome. Thanks a lot.
