Delivering Network
Innovation with SDN

Networks Have Not Adapted to Demands
Over the last 20 years…
© 2015 BROCADE COMMUNICATIONS SYSTEMS, INC. COMPANY PROPRIETARY INFORMATION 2
• Massively increased scale
(# of endpoints, switches, bytes, flows,
etc.)
• Static endpoints (weeks–months) to
dynamic endpoints (hours–days)
• Mostly north-south traffic to
mostly east-west traffic
Radically Shifting Network
Demands
• Link speeds have gone up, but…
• Still largely manage networks device-
by-device via the CLI
• If you’re lucky, orchestration at
the granularity of a few devices

Why Open Source?
• Avoid vendor
lock-in
© 2015 BROCADE COMMUNICATIONS SYSTEMS, INC. COMPANY PROPRIETARY INFORMATION 7HTTPS://18F.GSA.GOV/2014/11/26/HOW-TO-USE-MORE-OPEN-SOURCE/
“It's important that every Federal CIO, CTO, Architect, and Program Manager
seeking to build or procure new IT projects understand that open source exists,
that it can be of high quality and highly reusable, and how to use it securely.”
• Have a seat at
the table
• Faster
innovation
• Easier
integration

Open Source vs. Open Standards
© 2015 BROCADE COMMUNICATIONS SYSTEMS, INC. COMPANY PROPRIETARY INFORMATION 9
• Define interfaces well
– In human-readable documents
• Define behavior with some ambiguity
• Usually move slowly
• Leave interoperability testing to others,
e.g., users, integrators
• Sometimes provide open source
implementations
Open Standards
• Define interfaces well
– In code
• Define behavior in code so it
can be tested and understood
• Move and adapt quickly
• Can do interoperability testing
as part of development
• Often implement open standards
Open Source Projects

Is Open Source Secure?
• In general, open source is
considered to be more secure
than closed source software
– “Given enough eyeballs, all bugs
are shallow” –Linus
• Very strong security response process
– Fixed critical vulnerabilities and shipped
a new release in <4 days
• Device/user interfaces can be secured
– OF over SSL, NETCONF over SSH, RESTCONF over HTTPS w/auth
• Starting with Lithium, releases will be cryptographically signed

What Is OpenDaylight?
© 2015 BROCADE COMMUNICATIONS SYSTEMS, INC. COMPANY PROPRIETARY INFORMATION 14
OpenDaylight is an Open Source Software project under the Linux Foundation with
the goal of furthering the adoption and innovation of Software Defined Networking
(SDN) through the creation of a common industry supported platform.
To create a robust, extensible,
open source code base that
covers the major common
components required to build
an SDN solution
Code
To get broad industry acceptance
amongst vendors and users:
• Using it directly or through
vendor products
• Vendors using OpenDaylight
in commercial products
Acceptance
To have a thriving and growing
technical community
contributing to the code base,
using the code in commercial
products, and adding value
above, below and around.
Community

“ OpenDaylight is quickly
evolving into something
formidable with good
potential for mainstream
relevancy.”
“ OpenDaylight may be the
third center of gravity.”
– Andrew Lerner,
Gartner
“ OpenDaylight is
making steady progress
cultivating a growing
community of developers
and users interested
in adopting an open,
common SDN controller
platform.”
– Brad Casemore, IDC
Research Director for
Datacenter Networks
“ An open source
approach to software-
defined networking
(SDN) moved several steps
closer this week
to becoming a de
facto standard.”
– Mike Vizard,
IT Business Edge

• Historically, policy is mostly
– Rigidly enforced by the physical topology,
e.g., firewall at the gateway
– Configured “dynamically” via box-by-box
Access Control Lists (ACLs)
• New policy efforts are changing this
– Network Function Virtualization (NFV) and
Service Function Chaining (SFC)
– Automatically generated ACLs based on
network-wide policy
• OpenDaylight is a proving ground for
at least 3 policy-oriented projects
– Service Function Chaining, Group-Based Policy,
and Network Intent Composition
Network-wide policy monitoring and enforcement

SDN Is Here; It’s Time to Use It
© 2015 BROCADE COMMUNICATIONS SYSTEMS, INC. COMPANY PROPRIETARY INFORMATION 23
• SDN is the key to modernizing today’s networks
– Enables flexibility and choice
– Unlocks self-service innovation
• Open source is the force multiplier that makes SDN
possible
– Community leverage accomplishes more than any single
supplier
– Open philosophy shifts control from the suppliers to
the consumer
• Commercial versions of open source controllers are
production-ready with support
– e.g., the Brocade Vyatta Controller based on
unmodified OpenDaylight
– Brocade upstreams all changes to to OpenDayilght

• Figure out what infrastructure you have that is SDN-ready
– Some key protocols: NETCONF, OpenFlow, OVSDB
– Make current/future acquisitions call for this
• Ask your suppliers hard questions about software, agility,
and openness—it’s not just open standards anymore
• Download the code and start testing/deploying it
