The GBP Renderer Manager is the central point -for dispatching of data to specific device renderers. It uses the information -derived from the GBP end-point and its topology entries to dispatch the task -of configuration to a specific device renderer by writing a renderer policy -configuration into the registered renderer's policy store. The renderer -manager also monitors, by being a data change listener on the VPP Renderer -Policy States, for any errors in the application of a rendered configuration. - -**GBP VPP Renderer Interface Manager**: Listens to VPP endpoints in the -Config DataStore and configures associated interfaces on VPP via HoneyComb. - -**GBP VPP Renderer Renderer Policy Manager**: Manages the creation of -bridge domains using VBD and assigns interfaces to bridge domains. - -**Virtual Bridge Domain Manager (VBD)**: Creates bridge domains (i.e. in case -of VXLAN creates full mesh of VXLAN tunnels, configures split horizon on -tunnel endpoints etc.). VDB configures VXLAN tunnels always into a full-mesh -with split-horizon group forwarding applied on any domain facing tunnel -interface (i.e. forwarding behavior will be that used for VPLS). - -**Virtual Packet Processor (VPP) and Honeycomb server**: The VPP is the -accelerated data plane forwarding engine relying on vhost user interfaces -towards Virtual Machines created by the Nova Agent. The Honeycomb NETCONF -configuration server is responsible for driving the configuration of the VPP, -and collecting the operational data. - -**Nova Agent**: The Nova Agent, a sub-component of the overall Openstack -architecture, is responsible for interacting with the compute node's host -Libvirt API to drive the life-cycle of Virtual Machines. It, along with the -compute node software, are assumed to be capable of supporting vhost user -interfaces. - -The picture below shows the key components. - -.. image:: FDS-basic-components.jpg - -To provide a better understanding how the above mentioned components interact -with each other, the following diagram shows how the example of creating a -vhost-user port on VPP through Openstack Neutron: - -To create or update a port, Neutron will send a request to ODL Neutron -Northbound which contains the UUID, along with the host-id as "vpp" and -vif-type as "vhost-user". The GBP Neutron mapper turns the "Neutron speak" of -"ports" into the generic connectivity model that GroupBasedPolicy uses. -Neutron "ports" become generic "GBP Endpoints" which can be consumed by the -GBP Renderer Manager. The GBP Renderer Manager resolves the policy for the -endpoint, i.e. it determines which communication relationships apply to the -specific endpoint, and hands the resolution to a device specific renderer, -which is the VPP renderer in the given case here. VPP renderer turns the -generic policy into VPP specific configuration. Note that in case the policy -would need to be applied to a different device, e.g. an OpenVSwitch (OVS), -then an "OVS Renderer" would be used. VPP Renderer and the topology manager -("Virtual Bridge Domain" manager - i.e. VBD) cooperate to create the actual -network configuration. VPP Renderer configures the interfaces to the virtual -machines (VM), i.e. the vhost-user interface in the given case here and -attaches them to a bridge domain on VPP. VBD handles the setup of connectivity -between bridge domains on individual VPPs, i.e. it maintains the VXLAN tunnels -in the given case here. Both VPP Renderer as well as VBD communicate with the -device through Netconf/YANG. All compute and control nodes run an instance of -VPP and the VPP-configuration agent "Honeycomb". Honeycomb serves as a -Netconf/YANG server, receives the configuration commands from VBD and VPP -Renderer and drives VPP configuration using VPP's local Java APIs. - -.. image:: FDS-simple-callflow.png - - -Scenario Configuration -====================== - -To enable the "apex-os-odl_l2-fdio-ha" scenario check the appropriate -settings in the APEX configuration files. Those are typically found in -/etc/opnfv-apex. - -File "deploy_settings.yaml" choose opendaylight as controller with version -"carbon" and enable vpp as forwarder. Also make sure that you set -"ha_enabled" to "true" in the global_params section.

The main components of the -"apex-os-odl_l2-fdio-noha" scenario are: - - - APEX (TripleO) installer (please also see APEX installer documentation) - - Openstack (in non-HA configuration) - - OpenDaylight controller (non-clustered) controlling layer 2 networking - - FD.io/VPP virtual forwarder for tenant networking - -Introduction -============ - -NFV and virtualized high performance applications, such as video processing, -require a "fast data stack" solution that provides both carrier grade -forwarding performance, scalability and open extensibility, along with -functionality for realizing application policies and controlling a complex -network topology. - -A solution stack is only as good as its foundation. Key foundational assets for -NFV infrastructure are - * The virtual forwarder: The virtual forwarder needs to be a feature rich, - high performance, highly scale virtual switch-router. It needs to leverage - hardware accelerators when available and run in user space. - In addition, it should be modular and easily extensible. - * Forwarder diversity: A solution stack should support a variety of - forwarders, hardware forwarders (physical switches and routers) - as well as software forwarders. This way virtual and physical - forwarding domains can be seamlessly glued together. - * Policy driven connectivity: Connectivity should respect and - reflect different business - -In order to meet the desired qualities of an NFV infrastructure, the -following components were chosen for the "Openstack - OpenDaylight - FD.io" -scenario: - * FD.io Vector Packet Processor (VPP) - a highly scalable, - high performance, extensible virtual forwarder - * OpenDaylight Controller - an extensible controller platform which - offers the ability to separate business logic from networking - constructs, supports a diverse set of network devices - (virtual and physical) via the "group based policy (GBP)" - component, and can be clustered to achieve a highly available - deployment. - -The "Openstack - OpenDaylight - FD.io" scenario provides the capability to -realize a set of use-cases relevant to the deployment of NFV nodes instantiated -by means of an Openstack orchestration system on FD.io/VPP enabled compute -nodes. The role of the Opendaylight network controller in this integration is -twofold. It provides a network device configuration and topology abstraction -via the Openstack Neutron interface, while providing the capability to realize -more complex network policies by means of Group Based Policies. Furthermore it -also provides the capabilities to monitor as well as visualize the operation of -the virtual network devices and their topologies. -In supporting the general use-case of instantiatiting an NFV instance, two -specific types of network transport use cases are realized: - - * NFV instances with VPP data-plane forwarding using a VLAN provider network - * NFV instances with VPP data-plane forwarding using a VXLAN overlay - transport network - -A deployment of the "apex-os-odl_l2-fdio-noha" scenario consists of 4 or more -servers: - - * 1 Jumphost hosting the APEX installer - running the Undercloud - * 1 Controlhost, which runs the Overcloud as well as OpenDaylight - as a network controller - * 2 or more Computehosts - -.. image:: FDS-odl_l2-overview.png - -Tenant networking leverages FD.io/VPP. Open VSwitch (OVS) is used for all -other connectivity, in particular the connectivity to public networking / the -Internet (i.e. br-ext) is performed via OVS as in any standard OpenStack -deployment. The OpenDaylight network controller is used to setup and manage -layer 2 networking for the scenario. Tenant networking can either leverage -VXLAN (in which case a full mesh of VXLAN tunnels is created) or VLANs. Layer 3 -connectivity for a tenant network is provided centrally via qrouter on the -control node. As in a standard OpenStack deployment, the Layer3 agent -configures the qrouter and associated rulesets for security (security groups) -and NAT (floating IPs). Public IP network connectivity for a tenant network is -provided by interconnecting the VPP-based bridge domain representing the tenant -network to qrouter using a tap interface. The setup is depicted below: - -.. image:: FDS-L3-tenant-connectivity.png - -Features of the scenario ------------------------- - -Main features of the "apex-os-odl_l2-fdio-noha" scenario: - - * Automated installation using the APEX installer - * Fast and scalable tenant networking using FD.io/VPP as forwarder - * Layer 2 networking using VLANs or VXLAN, managed and - controlled through OpenDaylight - * Layer 3 connectivitiy for tenant networks supplied centrally on - the Control node through standard OpenStack mechanisms. - All layer 3 features apply, including floating IPs (i.e. NAT) - and security groups. - * Manual and automatic (via DHCP) addressing on tenant networks - -Scenario components and composition -=================================== - -The apex-os-odl_l2-fdio-noha scenario combines components from three key open -source projects: OpenStack, OpenDaylight, and Fast Data (FD.io). The key -components that realize the apex-os-odl_l2-fdio-noha scenario and which differ -from a regular, OVS-based scenario, are the OpenStack ML2 OpenDaylight plugin, -OpenDaylight Neutron Northbound, OpenDaylight (ODL) Group Based Policy (GBP), -OpenDaylight Virtual Bridge Domain Manager (VBD), FD.io Honeycomb management -agent and FD.io Vector Packet Processor (VPP). - -Here's a more detailed list of the individual software components involved: - -**Openstack Neutron ML2 OpenDaylight Plugin**: Handles Neutron data base -synchronization and interaction with the southbound controller using a REST -interface. - -**ODL GBP Neutron Mapper**: Maps neutron elements like networks, subnets, -security groups, etc. to GBP entities: Creates policy and configuration for -tenants (endpoints, resolved policies, forwarding rules). - -**ODL GBP Neutron VPP Mapper**: Maps Neutron ports to VPP endpoints in GBP. - -**ODL GBP Location Manager**: Provides real location for endpoints (i.e. Which -physical node an endpoint is connected to). - -**GBP Renderer Manager**: Creates configuration for Renderers (like e.g. -VPP-Renderer or OVS-Renderer). The GBP Renderer Manager is the central point -for dispatching of data to specific device renderers. It uses the information -derived from the GBP end-point and its topology entries to dispatch the task -of configuration to a specific device renderer by writing a renderer policy -configuration into the registered renderer's policy store. The renderer -manager also monitors, by being a data change listener on the VPP Renderer -Policy States, for any errors in the application of a rendered configuration. - -**GBP VPP Renderer Interface Manager**: Listens to VPP endpoints in the -Config DataStore and configures associated interfaces on VPP via HoneyComb. - -**GBP VPP Renderer Renderer Policy Manager**: Manages the creation of -bridge domains using VBD and assigns interfaces to bridge domains. - -**Virtual Bridge Domain Manager (VBD)**: Creates bridge domains (i.e. in case -of VXLAN creates full mesh of VXLAN tunnels, configures split horizon on -tunnel endpoints etc.). VDB configures VXLAN tunnels always into a full-mesh -with split-horizon group forwarding applied on any domain facing tunnel -interface (i.e. forwarding behavior will be that used for VPLS). - -**Virtual Packet Processor (VPP) and Honeycomb server**: The VPP is the -accelerated data plane forwarding engine relying on vhost user interfaces -towards Virtual Machines created by the Nova Agent. The Honeycomb NETCONF -configuration server is responsible for driving the configuration of the VPP, -and collecting the operational data. - -**Nova Agent**: The Nova Agent, a sub-component of the overall Openstack -architecture, is responsible for interacting with the compute node's host -Libvirt API to drive the life-cycle of Virtual Machines. It, along with the -compute node software, are assumed to be capable of supporting vhost user -interfaces. - -The picture below shows the key components. - -.. image:: FDS-basic-components.jpg - -To provide a better understanding how the above mentioned components interact -with each other, the following diagram shows how the example of creating a -vhost-user port on VPP through Openstack Neutron: - -To create or update a port, Neutron will send a request to ODL Neutron -Northbound which contains the UUID, along with the host-id as "vpp" and -vif-type as "vhost-user". The GBP Neutron mapper turns the "Neutron speak" of -"ports" into the generic connectivity model that GroupBasedPolicy uses. -Neutron "ports" become generic "GBP Endpoints" which can be consumed by the -GBP Renderer Manager. The GBP Renderer Manager resolves the policy for the -endpoint, i.e. it determines which communication relationships apply to the -specific endpoint, and hands the resolution to a device specific renderer, -which is the VPP renderer in the given case here. VPP renderer turns the -generic policy into VPP specific configuration. Note that in case the policy -would need to be applied to a different device, e.g. an OpenVSwitch (OVS), -then an "OVS Renderer" would be used. VPP Renderer and the topology manager -("Virtual Bridge Domain" manager - i.e. VBD) cooperate to create the actual -network configuration. VPP Renderer configures the interfaces to the virtual -machines (VM), i.e. the vhost-user interface in the given case here and -attaches them to a bridge domain on VPP. VBD handles the setup of connectivity -between bridge domains on individual VPPs, i.e. it maintains the VXLAN tunnels -in the given case here. Both VPP Renderer as well as VBD communicate with the -device through Netconf/YANG. All compute and control nodes run an instance of -VPP and the VPP-configuration agent "Honeycomb". Honeycomb serves as a -Netconf/YANG server, receives the configuration commands from VBD and VPP -Renderer and drives VPP configuration using VPP's local Java APIs. - -.. image:: FDS-simple-callflow.png - - -Scenario Configuration -====================== - -To enable the "apex-os-odl_l2-fdio-noha" scenario check the appropriate -settings in the APEX configuration files. Those are typically found in -/etc/opnfv-apex. - -File "deploy_settings.yaml" choose opendaylight as controller with version -"carbon" and enable vpp as forwarder.
