quantum: improving IPv6 support / pluggable IP allocation

Sign up or log in to save this to your schedule and see who's attending!

split session

This session will include the following subject(s):

Make IP allocation algorithm pluggable:

The default IP allocation algorithm works well on internal networks with its quick reuse and compact IP allocation strategy. On shared or public networks, this allocation scheme may not meet the providers security needs (rapid re-use by another tenant). In Grizzly, IP allocation should be pluggable by network, so that providers can choose the strategy that best fits their needs after weighing the space/time cost of each approach.

Proposed allocation approaches include:
first available ip
random
least recently used

Proposed recycling approaches include:
expiration delays
tenant affinity (ie on shared network a tenant is likely to get back the address they just released)
address space exhaustion before reclamation
DNS aware expiration (ie don't expire if DNS record is still pointing at IP).



Improving IPv6 support :

Quantum has rudimentary IPv6 support. In Grizzly we need to expand and polish the implementation.
- better DHCPv6 support
- fully working RA
- L3 Router support
- v6 firewall and/or security group support
- Automatic v6 subnet allocation/creation
