______________________________________________________________ prop-029-v001: Proposal for Discrete Networks and National Peering ______________________________________________________________ Authors: Uchenna N Ibekwe Vu, Baokhanh N (Beth) Jason Schiller Version: 2.0 Date: 3 September 2005 ---------------------------------------------------------------------------- Proposal to permit large ISPs to manage multiple country accounts under a single APNIC membership using discrete network concept. ---------------------------------------------------------------------------- Summary ---------------------------------------------------------------------------- This proposal is intended to simplify the management of multiple country accounts hereby each country account would be considered a discrete network. This proposal will support Global/Continental-Regional/National peering policies and would be vital for the implementation of the IPv6 routing policies. Benefits ---------------------------------------------------------------------------- 1. Simplify management of multiple country accounts; Currently large ISPs such as MCI with multiple APNIC accounts (one per country) using the concept of discrete network can simplify their procedures by combining their membership accounts under a single account, while managing each country IP allocation as separate discrete networks. 2. Simplify Billing; This concept will simplify the billing requirement for APNIC, hereby reducing the number of member accounts per ISP and unify the billing cycles. 3. Peering; Most large ISPs with International networks spanning multiple continent and regions have peering policies implemented on their network. Currently, MCI has 3 levels of peering, namely global-peering, continental-regional peering and National peering. In order to make national peering work in IPv6, we will need to advertise a single aggregate per country. This will typically a /32, each country /32 should be able to be aggregate into a single aggregate so that a single announcement could be made to customers and continental-regional peers. In some countries, it is required by law that we peer with other ISPs or interconnect at NAP (Network Access Point). In this case, the issue of peering is required and this can only be done using aggregated IPv6 addresses which will be based on the level of peering (It can be Global/Continental-regional/National peering). 4. This proposal does not conflict with current APNIC policy; only seeks to simplify current APNIC operational requirements, frameworks for management and allocation of IPv6/IPv4 addresses. This policy will be vital to integration of implantation of IPv6 into an Asia Pacific region. Case Study ---------------------------------------------------------------------------- Some organizations have requirements for multiple discrete networks that need individual address allocations. Discrete networks must often have separate unique globally routable address space and will often grow at different rates. In order for organizations with multiple discrete networks to request additional address space under a single maintainer ID, the organization must use the following criteria: * The organization should be a single entity, and not a consortium of smaller independent entities. * This policy applies only to organizations that have been previously granted address space by an RIR. This policy does not apply to organizations with only legacy address space. * The organization must have multiple (at least two) discrete multi-homed networks. * The organization must have compelling criteria for creating discrete networks. Examples: o regulatory restrictions for data transmission o geographic distance and diversity between networks o autonomous multi-homed discrete networks * The organization must apply for this policy to be applied to their account. Other APNIC IP allocation policies for IPv6/IPv4 would apply to this proposal. Proposal ---------------------------------------------------------------------------- 4.1 When applying for additional address space from an RIR for new networks or additional space for existing discrete networks the organization must show greater than 50% utilization (IPv4) for the last block granted by the RIR and their allocations as a whole. For IPv6 discrete networks existing HD ratio policies apply. 4.2 The organization must not issue additional IP address space to a discrete network unless all the blocks sub-allocated to that network show utilization greater than 80% individually for IPv4 and existing HD ratio policies for IPv6. 4.3 The organization must not sub-allocate a CIDR block larger than the current minimum allocation size of the RIR (currently /21-IPv4, /32-IPv6 for APNIC region) to a new network. 4.4 The organization must not sub-allocate an additional CIDR block larger than the current minimum allocation size of the RIR (currently /21-IPv4, /32-IPv6 for APNIC 's region) to an existing network, unless previous growth rates for that network indicate that it is likely to utilize a larger CIDR block before the time the organization will be requesting an additional block from the RIR. 4.5 When sub-allocating a block larger than the minimum allocation size to an existing network the ISPs should use the smallest allocation possible out of a larger reserved block. This requirement is to reduce the number of routes the ISPs will announce from that autonomous system. 4.6 The ISPs must follow guidelines of RFC 2050 (or its replacement) and the policy of the granting RIR for allocations that are assigned or sub-allocated to downstream networks. This includes record keeping of IP address requests and network utilization documents for audits by the RIR. 4.7 ISPs with 'multiple membership accounts' should request that this policy apply to them, their existing allocations be merged, and that additional allocations will fall under this policy. 4.8 The ISPs must record sub-allocations or assignments down to the current RIR bit boundary and record them in an approved RIR public database. 4.9 The ISPs must keep detailed records of how it has sub-allocated space to each discrete network. This should include the block sub-allocated, any reserved blocks, and date of allocation/ reservation. The discrete network allocation information should also be present in a public database. 4.10 An assignment window will be assigned to the ISPs and will need to be followed for their entire network. Second opinion requests will need to be sent to APNIC for review. This is to include blocks of addresses that are assigned to new or existing pools within the ISPs network. Fees ---------------------------------------------------------------------------- The IP addresses from all combined resources would be taken into account when assessing the membership tier for the organization upon the renewal of their membership.
