Newton Series Release Notes

New Features

  • Initial release of the OpenStack Networking service (neutron) integration with Open Virtual Network (OVN), a component of the the Open vSwitch project. OVN provides the following features either via native implementation or conventional agents:

    • Layer-2 (native OVN implementation)

    • Layer-3 (native OVN implementation or conventional layer-3 agent) The native OVN implementation supports distributed routing. However, it currently lacks support for floating IP addresses, NAT, and the metadata proxy.

    • DHCP (native OVN implementation or conventional DHCP agent) The native implementation supports distributed DHCP. However, it currently lacks support for IPv6, internal DNS, and metadata proxy.

    • Metadata (conventional metadata agent)

    • DPDK - Usable with OVS via either the Linux kernel datapath or the DPDK datapath.

    • Trunk driver - Driver to back the neutron’s ‘trunk’ service plugin
