Features¶
Dragonflow offers the following virtual network services:
Layer-2 (switching)
Native implementation. Replaces the conventional Open vSwitch (OVS) agent.
Layer-3 (routing)
Native implementation or conventional layer-3 agent. The native implementation supports distributed routing. In the process of supporting distributed DNAT. SNAT is centralized at networking node.
DHCP
Distributed DHCP application that serves DHCP offers/acks locally at each compute node.
Metadata
Distributed Metadata proxy application running locally at each compute node.
DPDK
Dragonflow shall work to support using OVS DPDK as the datapath alternative, this depends on the supported features in OVS DPDK and the VIF binding script support in Neutron plugin.
