ODL Neutron Providers OpenStack Neutron networking-odl • Single common northbound REST interface towards OpenStack Neutron Northbound • Multiple implementations in ODL MD-SAL that can serve as Neutron providers • NetVirt NetVirt GBP • GBP (GroupBasedPolicy) MD-SAL Southbound Protocols & Plug-ins

ODL NetVirt Solution OpenStack Neutron • One of the OpenStack service providers networking-odl in OpenDaylight REST API Neutron Northbound • Services: L2, L3 (IPv4/v6), BGP L3VPN, EVPN, ACL, DHCP, QoS, SFC, L2GW Neutron Data Store (MD-SAL) NetVirt • Translates NB constructs to forwarding NetVirt Neutron Mapper plane agnostic service yang models NetVirt Service Model Data Store (MD-SAL) Overlay L2/ELAN L3/VPN ACL DHCP • Supports OpenFlow and OVSDB based Tunnel Service Service Service Service Mgr devices OVS Renderer HWVTEP Renderer OpenFlow OVSDB NetConf BGP • BGP and Netconf to interwork with physical legacy routers OVS with Virtual Switches HW Gateways/ToRs Routers Acceleration

ODL NetVirt Solution POST PORT (id=<uuid>, vif_type=normal) Neutron (networking-odl driver) Update Port in Neutron MD-SAL store ODL Neutron Northbound NetVirt receives DCN (Data Change Notification) from MD-SAL NetVirt Neutron Mapper Map Neutron Port to NetVirt ELAN data model (ELANInterface) Receive OpenFlow PORT_UP notification for Port <uuid> that Overlay Tunnel Mgr NetVirt ELAN/L2 Service provide the host information to which ELANinterface is bound Create VXLAN Tunnel Endpoints Program OpenFlow Flow rules to allow traffic from Port <uuid> NetVirt OVS Renderer OpenFlow Plugin OVSDB Plugin OVSDB OF OF VTEP port-create port-up flow/group-create OVS 1 OVS 2 VM VXLAN Tunnel

ODL GroupBasedPolicy (GBP) Solution OpenStack Neutron networking-odl • Intent driven policy framework (control and REST API forwarding policy) in OpenDaylight Neutron Northbound • Contract-based, policy-driven connectivity abstraction; generic endpoint identification Neutron Data Store (MD-SAL) • Generic northbound interface Topology (adapter for Neutron-Northbound available) GBP Management • Flexible southbound interfaces supported: GBP Neutron Mapper LISP LISP Flow • NetConf/YANG (for FD.io/VPP) GBP Model Data Store (MD-SAL) Mapping Service • OF/OVSDB (for OVS) GBP Location & Renderer Manager VBD Topology Mgr OVS Overlay Renderer VPP Renderer (VBD) • Services: Access-control policies (“ACLs”), Forwarding policies (“L2VPN/ELAN”, OpenFlow OVSDB NetConf BGP “L3VPN”) Honeycomb VPP Virtual Switches Routers FD.io Devices

ODL GBP/VBD Solution POST PORT (id=<uuid>, host_id=vpp2, vif_type=vhostuser) Neutron (networking-odl driver) Update Port in Neutron MD-SAL store ODL Neutron Northbound GBP receives DCN (Data Change Notification) from MD-SAL GBP Neutron Mapper Map Neutron Port to GBP Endpoint Apply Policy Update device end point GBP Renderer Manager Update node(s), bridge-domain Topology Manager (VBD) VPP Renderer Netconf Plugin Netconf Commit Netconf Commit (bridge-config, tunnel-config) (vhostuser i/f config, bridge-config) Honeycomb Honeycomb VXLAN Tunnel VM VPP 1 VPP 2 vhostuser

Need for an Integrated Control solution What we have What we want • OpenDaylight NetVirt and GBP are both • ODL Nirvana : Single network control network control solutions, each with its solution in OpenDaylight own strengths • Provide rich set of common control • Both intended to support multiple services northbound APIs and diverse set of southbound protocols & devices • Provide broad support for different southbound forwarders (OVS, VPP, Hardware,...) • Two communities focused on two different applications with the same goals. • Single Community that moves as one team with one direction

ODL Integrated Control Solution OpenStack Neutron networking-odl • NirvanaStack Approach : REST API Integrated Control solution in OpenDaylight Neutron Northbound Neutron Data Store • Services: L2, L3, BGP L3VPN, EVPN, ACL, (MD-SAL) DHCP, QoS, SFC, IPv6, L2GW Integrated Neutron Mapper • Diverse set of forwarders: OpenFlow and Service Model Data Store (MD-SAL) OVSDB based devices, Netconf based LISP L3/VPN L2/ELAN Service ACL Service Flow Mapping Service devices (FD.io) Topology Mgr Renderer Manager (VBD) OVS HWVTEP HW VPP Renderer Renderer Renderer Renderer • BGP and Netconf to interwork with physical routers/switches OpenFlow OVSDB NetConf BGP Honeycomb VPP OVS with Virtual Switches HW Gateways/ToRs Routers Acceleration FD.io Devices

ODL Integrated Solution: PoC: ELAN service with FD.io/VPP POST PORT (id=<uuid>, host_id=vpp2, vif_type=vhostuser) Neutron (networking-odl driver) Update Port in Neutron MD-SAL store ODL Neutron Northbound Data Change Notification(DCN) from MD-SAL Neutron Mapper Map Neutron Port to NetVirt ELAN data model (ELANInterface) Apply Policy If interface is on a netconf node and is of type vhostuser , NetVirt ELAN/L2 Service VPP Renderer Manager Configure bridge-domains and vhostuser interface Update node(s), bridge-domain Topology Manager (VBD) VPP Renderer Netconf Plugin Netconf Commit Netconf Commit (bridge-config, tunnel-config) (vhostuser i/f config, bridge-config) Honeycomb Honeycomb VXLAN Tunnel VPP 1 VPP 2 VM vhostuser

Current Status • Design discussions are in progress in the ODL community • Proof-of-concept is done to demonstrate simple ELAN/L2 service with OpenDaylight integrated control solution and FD.io data plane • Near-term Roadmap • Realization of L3VPN service • Realization of SFC service • Realization of VLAN transparency/trunking/Q-in-Q features • Validation in hybrid deployments (OVS and VPP)
