Current network services network ACL and routing support by CloudStack for east-west traffic (inter-tier traffic) can be orchestrated to be provided by virtual switches in hypervisors. Goal of this proposal to add distributed routing and firewall functionality to native SDN controller that leverages OpenVswith capabilities to provide inter-tier routing and network ACL's at hypervisor level in distributed fashion. This would enable a scale-out model and VPC VR being choke point is avoided. Also traffic trombone problem is eliminated as traffic gets routed directly to destination hypervisor from source hypervisor.
