  1. IPv6 Reservation for Large Network Xing Li, Song Jiang, Xiaomin Zhou, Haijin Li 2011-08-30

  2. The problem

  3. Standard Allocations 1st alloc 2nd alloc 3rd alloc /29 /29 /28 HQ POP1 POP2 POP3 POP4 POP5

  4. Standard Allocations Problem: Fragmentised space in each POP, resulting in a complex internal routing configuration

  5. Proposed solution

  6. Proposed Allocations /27 Reserved Space /29 1st alloc /31 /32 /32 /31 /32 /32 /29 2nd alloc /32 /31 /31 /32 /32 /32 3rd alloc /28 /31 /31 /31+/32 /31 /31+/32 /30 HQ POP1 POP2 POP3 POP4 POP5

  7. Proposed Allocations Solution: Aggregated space in each POP, resulting in a simpler internal routing configuration

  8. Proposal Summary • Allow reservation for large IPv6 networks • Reservation size based on the network’s long term planning, up to 10 years • The reservation qualification gets reviewed every 2 year • Allocations can be made in single/multiple prefixes from the reserved space

  9. FAQ • How many prefixes will we see globally announced from these large networks? • It will roughly correspond to the number of major POPs they have • The number of prefixes will be reduced over time as the reserved space gets filled • Why not just allocate the whole reserved space up-front? • Things might change during the 5-10 year planning window. The reserved space might grow/shrink so it is best to manage this space as part of the bigger pool available at APNIC during the deployment stages

  10. FAQ • Can the network announce the whole reserved space? • No. Whois will not show the reserved space. • Certification will only be given to the allocated blocks.
