Goal is to discuss how to integrate various features of the existing nova-network service other than L2 forwarding into the Quantum model. These include: DHCP, floating IPs, VPN, NAT, L3 gateway, the metadata server, as well as IPAM (handled by Melange) The goal here will be to design the workflow + toolset when using Quantum with these higher level capabilities. If using Quantum + Melange + other network services is too complicated, folks won't do it. Note: the determination here may be that we slice certain functionality off into a dedicated service, implement it as a sub-part of Quantum, or keep it in nova. If we decide to re-implement the functionality either as a sub-service of Quantum or as a separate service, we would have a separate discussion to actually design the new service or sub-service.
