The goal of this design session is to settle on a framework for how we expect to integrate advanced network services with Quantum. Note: this session is designed to be a pre-requisite for discussion on particular higher-level services (e.g., Firewalls/ACLs, L3, Load-balancing, etc.) Its goal is NOT to actually design any particular higher-level service. Those will be covered in subsequent sessions. Topics covered will include whether higher-level services should be a part of Quantum proper, and if so, how to support different pluggable backends implementing different services, how to handle conflicting designs for a single service (e.g., two participants want different APIs for WAN bridging), and other fun topics in the same vein.
