2. Use Case Discussion (zhipeng, 08:11:14)
   1. use case 2 (zhipeng, 08:16:43)
   2. I'm was focussing on the need to be able to redirect external traffic between application instances sitting in one or more "local" clouds. (colintd, 08:36:58)
   3. Where the example was suggested (I missed who) of a VNF implementing VRRP, with one instance in each of two clouds, and the question being what config/changes are needed to allow this to work ( is anti-spoof an issue) (zhipeng, 08:38:17)
   4. I'm was focussing on the need to be able to redirect external traffic between application instances sitting in one or more "local" clouds. (colintd, 08:38:43)
   5. We also talked about SND controllers, and how in many telco deployments these control much broader end-to-end traffice than simply intra-cloud. They might however be implemented using multiple redundant control nodes, say one per cloud, but providing a global function. (colintd, 08:39:46)
   6. In this case neutron may be used to "connect" to those networks, but isn't the major control interface for the whole system, just a "joining" interface (colintd, 08:40:17)
   7. Finally, returning to traffic failover, we talked about how for L2 failover can be triggered by apps just using GARP, but L3 requires protocol level (BGP/SDN) API. We also talked about how L3 convergence times (say BGP) might be too slow by default, especially in error cases (loss of node) as opposed to managed failover. (colintd, 08:42:03)
   8. HA with VRRP http://blog.aaronorosen.com/implementing-high-availability-instances-with-neutron-using-vrrp/ (sorantis, 08:57:36)
   9. We are looking at similar function between clouds, for which this may or may not need to be extended. May also be interplay with provider networks. (colintd, 08:58:18)
   10. I will investigate before the next meeting. (colintd, 08:58:27)
