7. People Like SDN Because
SDN promises to make networks:
1. Dynamically provisioned
2. Provide scalable capacity
3. Provide abstracted HW complexity
4. Bandwidth on demand
8. Arming Yourself To Explore This
New Frontier
Transformation of Network
Engineer
1. Programming skills
2. Tools
3. Getting your hands dirty
11. 5 Reasons Why You Should
Learn Basic Programming
1. You’re already programming, even if you don’t know it
2. Everything has an API
3. It’s all about the applications
4. Prototypes
5. New skills, new opportunities

15. What Languages To Learn
S Focus on languages for the APIs you are using
S Java
S Python
S Maybe C and/or C++
17. IRC (Internet Relay Chat)
S
Open Source projects all use
IRC
S
Recommended channels in
Open Source networking:
S #openstack-neutron
S #opendaylight
S #opendaylight-ovsdb
S #openvswitch
18. Mailing Lists
S
Open Source projects all use
mailing lists for communication
S Documents things in the
archives
S Allows searching for new
participants
19. git
S
Source code management tool
of choice
S github is used to share code
S Most projects use github
S If github is not used, the
projects likely have their
own git server
S
Get a github ID
S https://github.com/
20. Wikis
S
All Open Source projects have
Wikis
S
Provide an easy way to share
information
S Warning: Information can get
stale
S Warning: Humans don’t like
correcting stale information
S
An easy way for new contributors
to help is to update wikis!
22. Linux
S
The kernel of choice in the Open Source
world
S
KVM or Xen for virtualization
S
OpenStack
S
CloudStack
S
Prevalent in IaaS world
S
Amazon AWS
S
Rackspace
S
Popular Switch Operating System
S
Cisco NX-OS
S
Arista EOS
S
Cumulus Linux
24. Open vSwitch
S
Open vSwitch is an Open Source
extensible virtual switch
S Licensed under the Apache
2.0 and GPL licenses
S
Supports a wide array of
protocols
S Netflow
S sFlow
S SPAN
S RSPAN
S CLI
S LACP
25. Open vSwitch Specifics
S
Security
S
Overlay network building block
S
Monitoring
S
Used by many virtualization and
IaaS platforms
S
QoS
S
Kernel module is upstream
S
Many Linux platforms
supported
S
Automated Control
27. OpenDaylight
OpenDaylight’s mission is to
facilitate a community-led, industrysupported open source
platform, including code and
architecture, to accelerate adoption
of Software-Defined Networking
and Network Functions
Virtualization.
31. OpenStack
To produce the ubiquitous open
source cloud computing platform
that will meet the needs of public
and private cloud providers
regardless of size, by being simple
to implement and massively
scalable.

36. devstack
DevStack’s mission is to provide
and maintain tools used for the
installation of the central
OpenStack services from source
(git repository master, or specific
branches) suitable for development
and operational testing. It also
demonstrates and documents
examples of configuring and
running services as well as
command line client usage.
40. Building Blocks Are Here
Applications!
Yay to applications!
Automation
DevOps at scale!
OpenDaylight
OpenStack or CloudStack or Eucalyptus
or oVirt
Linux (Fedora, Ubuntu, Red Hat, etc.)
Xen or KVM
SDN for the
masses!
IaaS for the
masses!
At the heart of all of
this …
