This document discusses the role of SDN controllers in OpenStack. It provides background on SDN controllers and OpenStack. SDN controllers can be integrated with OpenStack via the Neutron module to manage network flows and enable programmability. Several SDN controllers that integrate with Neutron are discussed, including OpenDaylight, OpenContrail, and ONOS. The document outlines how these controllers plug into Neutron and their current status in OpenStack. It provides guidance on how new SDN controllers can join OpenStack.

- 4. HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential 4 What is a SDN Controller? An SDN controller is an application in software-defined networking (SDN) that manages flow control to enable intelligent networking. SDN controllers are based on protocols, such as OpenFlow, that allow servers to tell switches where to send packets.
- 5. HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential 5 Word about OpenStack o OpenStack can be considered to be not one project but several, consisting of compute, storage and networking. o All three platform components are managed by a dashboard Web application. o Combined, they can provide a complete cloud network operating system.
- 6. HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential 6 OpenStack module to talk about: Neutron o Neutron was introduced to treat networking as a separate service. o Can run as an autonomous service, exposes APIs with different vendors, provides implementations by appropriate extensions. o In short, neutron is NOT SDN, but in theory can transform anything into SDN, Just provide a plug-in for it.

- 9. HUAWEI TECHNOLOGIES CO., LTD. Huawei Confidential 9 OpenStack Neutron, with its plug-in architecture, provides the ability to integrate SDN controllers into the OpenStack. provides centralized management, and facilitates the network programmability using APIs. OpenStack is relatively mature and is in use in production environments worldwide. This enables organizations to take advantage of the network orchestration feature without necessarily deploying a full-blown controller-led SDN solution. Different integration options: Completely eliminate RPC communications between the Neutron server and agents on the compute node, with the SDN controller being the sole entity managing the network. SDN controller manages only the physical switches, and the virtual switches can be managed from the Neutron server directly.
