2.13. OpenStack Networking

This section outlines the top new features for the Networking service.

Native Open vSwitch Firewall Driver: The OVS firewall driver has graduated from Technology Preview to full support. The conntrack-based firewall driver can be used to implement Security Groups. With conntrack, Compute instances are connected directly to the integration bridge for a more simplified architecture and improved performance.
Layer-2 Gateway API: The Layer-2 Gateway is a service plugin which allows you to bridge networks together so they appear as a single L2 broadcast domain. This update introduces support for the Layer-2 Gateway API.
BGP/VPN API: OpenStack Networking now supports BGPVPN capabilities. BGPVPN allows your instances to connect to your existing layer 3 VPN services. Once a BGPVPN network is created, you can associate it with a project, allowing the project's users to connect to the BGPVPN network.
