The document summarizes the key plans and goals for OpenStack Networking (Neutron) in the Juno release, including: achieving parity with nova-network, implementing distributed virtual routing, making the database independent of plugins, focusing on third-party testing, introducing a new LBaaS API, adding group policy APIs, providing HA for L3 routers, and integrating NFV features. It also lists new in-tree plugins being merged or proposed.
Networking Updates - Juno Edition
- 1. Networking PTL Kyle Mestery Juno Update OpenStack Networking
- 2. To implement services and associated libraries to provide on-demand, scalable, and technology- agnostic network abstraction.
- 3. Neutron Juno Project Plan https://wiki.openstack.org/wiki/NeutronJunoProjectPlan ● Organize high-level community tasks into Juno milestones ● Be transparent with developers and the community around what we want to land in Juno ● Provide a roadmap for distributions to plan for what features will land in Juno
- 4. Achieving parity with nova-network ● Icehouse set the groundwork for achieving this ● In Juno, the gap will be closed by following a plan put in place with guidance from the TC ● https://wiki.openstack.org/wiki/Governance/TechnicalC ommittee/Neutron_Gap_Coverage ● Migration script from nova-network to neutron
- 5. Distributed Virtual Router (DVR) ● Implements L3 routing across compute nodes ● Implements floating IP namespaces per compute node ● SNAT remains centralized on a service node
- 6. Neutron DB Updates and Migrations ● Starting from Juno, the Neutron DB will be made independent of the core and service plugins ● All migrations will be made unconditional ● Upgrade and downgrades around the healing migration will be supported
- 7. Focus On Third Party Testing ● An increased focus on providing consistent, repeatable testing for third party plugins ● Documented requirements and policies around this
- 8. Load Balancing as a Service ● Brand new LBaaS API in Juno ● In-tree ha-proxy driver will be updated to reflect new API and object model ● Octavia Project on Stackforge is meant to be an Operator Grade implementation
- 9. Group Based Policy API ● An extension to the Neutron API ● Provides a declarative policy driven connectivity model ● Presents application centric APIs to users
- 10. HA for L3 Routers ● Provides HA for L3 virtual routers ● Implemented as an extension API with pluggable drivers ● In-tree implementation will utilize keepalived
- 11. Flavor Framework ● A way for operators to offer network services to their clients ● Allows separation of driver functionality and configuration from consumers of services ● Allows operators to offer service levels based on multiple driver backends, features, etc.
- 12. Neutron NFV Work ● Working with the NFV sub-team in OpenStack to integrate features relevant in this space ● Service chaining, traffic steering, etc.
- 13. New In-Tree Plugins Merged ● Cisco APIC ML2 MechanismDriver and L3 Plugin ● Freescale SDN ML2 MechanismDriver
- 14. New In-Tree Plugins Proposed ● A10 Networks LBaaS Driver ● Brocade Vyatta L3 Plugin ● Cisco DFA ML2 MechanismDriver ● Huawei ML2 MechanismDriver ● IBM SDN-VE ML2 MechanismDriver ● LVS LBaaS Driver ● ML2 MechanismDriver for SR-IOV capable NIC based switching ● OpenContrail Plugin ● SNMP ML2 MechanismDriver ● Snabb Switch ML2 MechanismDriver ● VMware dVS ML2 MechanismDriver
- 15. Things disappearing in Juno ● Open vSwitch plugin ● Linuxbridge plugin
