Kilo Update
OpenStack Networking

2. To implement services and associated libraries to
provide on-demand, scalable, and technology-
agnostic network abstraction.

3. Neutron Kilo Priorities
http://git.openstack.org/cgit/openstack/neutron-specs/tree/priorities/kilo-priorities.rst
● Ensure each prioritized task has a specification
associated with it
● Prioritize high-level community tasks into Kilo
milestones
● Be transparent with developers, users, and
distributions around what we want to land in Kilo
● Provide a roadmap for distributions to plan for
what features will land in Kilo

4. Achieving parity with nova-network
● Icehouse set the groundwork for achieving this
● In Juno, features such as DVR closed the
functionality gap
● During Kilo, the focus will be on migrating nova-
network installs to Neutron

5. REST / RPC / Plugin API Refactor
● Focused on paying down technical debt by
refactoring the core of Neutron
● This will enable better support for out of tree
extensions
● Switching to pecan from homegrown WSGI

6. Plugin Decomposition
● Addresses pain points: review time, iteration
speed, easier to use vendor specific modules
● Move to thin in-tree plugins and drivers, with
plugin and driver functionality maintained outside
of Neutron
● Allows for fast iteration for both core Neutron as
well as plugins and drivers

7. Testing
● Full-stack testing
● Functional testing of OVS, LB, DHCP and
metadata agents
● Retargetable functional tests

8. Agent Refactoring
● L2 Agent
●Scalability
●Agent functional testing
●RPC improvements
●OVSDB monitoring improvements
● L3 Agent
●Scalability
●Paying down technical debt
●Abstracting out service agents
● DHCP Agent
●Scalability
●Restart improvements
●Load based scheduling
●Dead agent rescheduling
●Functional Tests

9. Advanced Services Split
● Migrate out LBaaS, VPNaaS, and FWaaS into
separate git repositories
● Allow operators the flexibility of running the
services they want to offer their tenants
● Allow the services teams the chance to iterate
quickly outside the scope of core neutron
● Reduce gate testing complexity
● Optimize core parts of Neutron into a library

10. Pluggable IPAM
● Create a pluggable IPAM system inside of
Neutron
● Allows the use of third-party and vendor IPAM
system

11. Speed and Reliability Improvements
● Agent Child Process Status: Monitors agents and
restarts them when they exit
● Rootwrap Daemon Mode: High performance
access to root for commands run by Neutron
agents

12. 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 configure additional vendor
features in an end-user agnostic way

13. Neutron NFV Work
● Working with the NFV sub-team in OpenStack to
integrate features relevant in this space
● More seamlessly connect hardware and neutron
L2 segments
● Trunk ports to virtual machines

14. New Plugins Proposed
● A10 Networks LBaaS V2 Driver
● Brocade Vyatta FWaaS, L3, LBaaS and VPNaaS Drivers
● ML2 MechanismDriver for Project Calico
● Cisco Nexus 1000v ML2 MechanismDriver
● Cisco UCS ML2 MechanismDriver
● Freescale FWaaS Plugin
● Huawei ML2 MechanismDriver
● IBM SDN-VE ML2 MechanismDriver
● Infoblox IPAM/DHCP Plugin
● Neutron OVS Agent on Windows
● Mcafee NGFW FWaaS Driver

15. Things disappearing in Kilo
● Ryu Plugin (ML2 + ofagent replaces this)
