(c) <optionally add copywriters name> - -Introduction -============ -.. In this section explain the purpose of the scenario and the types of capabilities provided - -The os-odl_l2-sfc-ha is intended to be used to install the OPNFV SFC project in a standard -OPNFV High Availability mode. The OPNFV SFC project integrates the OpenDaylight SFC project -into the OPNFV environment. The OPNFV SFC Danube release uses the OpenDaylight Boron SR2 release. - -Scenario components and composition -=================================== -.. In this section describe the unique components that make up the scenario, -.. what each component provides and why it has been included in order -.. to communicate to the user the capabilities available in this scenario. - -This scenario installs everything needed to use the SFC OpenDaylight project in an OPNFV -environment. The classifier used in this scenario is implemented by the Netvirt OpenDaylight -project. - -Following is a detailed list of what is included with this scenario: - -OpenDaylight features installed -------------------------------- - -The OpenDaylight SDN controller is installed in the controller node. - -The following are the SFC features that get installed: - -- odl-sfc-model -- odl-sfc-provider -- odl-sfc-provider-rest -- odl-sfc-ovs -- odl-sfc-openflow-renderer - -The following are the Netvirt features that get installed: - -- odl-ovsdb-openstack -- odl-mdsal-xsql -- odl-neutron-service -- odl-neutron-northbound-api -- odl-neutron-spi -- odl-neutron-transcriber -- odl-mdsal-apidocs -- odl-ovsdb-southbound-impl-rest -- odl-ovsdb-southbound-impl-ui - -By simply installing the odl-ovsdb-openstack feature, all the dependant features -will automatically be installed. - -The VNF Manager ---------------- - -In order to create a VM for each Service Function, a VNF Manager is needed. The OPNFV -SFC project currently uses the Tacker OpenStack project as a VNF Manager. Tacker is -installed on the controller node and manages VNF life cycle, and coordinates VM creation -with the OpenDaylight SFC project. - -Scenario usage overview -======================= -.. Provide a brief overview on how to use the scenario and the features available to the -.. user. This should be an "introduction" to the userguide document, and explicitly link to it, -.. where the specifics of the features are covered including examples and API's - -Once this scenario is installed, it will be possible to create Service Chains and -classification entries to map tenant traffic to individual, pre-defined Service Chains. -All configuration can be performed using the Tacker CLI. - -Limitations, Issues and Workarounds -=================================== -.. Explain scenario limitations here, this should be at a design level rather than discussing -.. faults or bugs. If the system design only provide some expected functionality then provide -.. some insight at this point. - -The *client* virtual machine needs to be located in a compute node where at least -one of the service functions (SFs) is placed. This is due to a limitation in OpenDaylight, -Boron, which only installs the traffic classifier in the compute nodes where the SFs are. - -Specific version of OVS ------------------------ - -SFC needs changes in OVS to include the Network Service Headers (NSH) Service Chaining -encapsulation. This OVS patch has been ongoing for quite a while (2 years+), and still -has not been officially merged. Previously, SFC used NSH from a branched version of OVS -based on 2.3.90, called the "Pritesh Patch". In the OpenDaylight Boron SR2 release, SFC was -changed to use a newer, branched version of OVS based on 2.6.1, called the "Yi Yang -Patch". - -The older version of OVS only supported VXLAN-GPE + NSH encapsulation, but the newer -version supports both ETH + NSH and VXLAN-GPE + ETH + NSH. Currently SFC is only -implemented with VXLAN-GPE + ETH + NSH. - -Workaround for VXLAN and OpenStack ----------------------------------- - -When using NSH with VXLAN tunnels, its important that the VXLAN tunnel is terminated -in the SF VM. This allows the SF to see the NSH header, allowing it to decrement the -NSI and also to use the NSH metadata. When using VXLAN with OpenStack, the tunnels -are not terminated in the SF VM, but in the “br-int” OVS bridge. A work-around has -been created to address this issue, which can be found here: - -http://artifacts.opnfv.org/sfc/danube/docs/design/architecture.html#ovs-nsh-patch-workaround - -In subsequent versions of SFC, we will change the SFF-SF transport to be ETH + NSH, -which will obviate this work around. - -References -========== - -For more information about SFC, please visit: - -https://wiki.opnfv.org/display/sfc/Service+Function+Chaining+Home - -https://wiki.opendaylight.org/view/Service_Function_Chaining:Main - -For more information on the OPNFV Danube release, please visit: - -http://www.opnfv.org/danube - |
