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.

1. Networking PTL

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
