3. SDN/OPENFLOW
THE END OF THE WORLD AS WE
KNOW IT?

SDN THE END OF NETWORKING AS WE KNOW IT?
This is just the beginning…
The network is the glue that makes virtualization work
Server virtualization is
driving changes in the
network, but the network
is not a commodity
Reliability through process
UPTIME SCALE COST
The Ideal Network?

THE VALUE OF NETWORKING
COMMUNICATION AND WORKLOAD
Network
Programmability
THE APPLICATION WORLD THE NETWORK WORLD
Inform application of data intrinsically
in the network
Inform network of desired behavior
§ Bi-Directional
Communications
§ Network edge has highest
rate-of-change
§ Existing provisioning
systems are first attempt
(mostly uni-directional)
What is needed is programmatic bridging of application-network divide
LANData Center
WAN
Data Center
Network Scope Widening
Orchestration:
Dynamic Workloads
Compute, Storage,
Network as one
resource pool
Trend #1 Trend #2

NETWORK PROGRAMMABILITY:
APPLYING THE KNOWLEDGE
Proper orchestration requires an understanding of:
Locality & Affinity
Compute/Storage/External Resources
Bi-Directional APIs: Bridge the Application and Network Worlds
§ High Rate of Change
§ Externally Controlled
§ Policy Enforcement
§ Publish Topology and Instrumentation
§ Programmed Topology/Path
§ Guarantee Reliable Communications

What the Application Wants

7. 5 Copyright © 2012 Juniper Networks, Inc. www.juniper.net
PROGRAMMABILITY OCCURS AT MULTIPLE LAYERS
Examine Available Toolkit
§ Programmatic control for high rate-of-
change operations (ex: forwarding state)
§ Abstraction layers to manage complexity
Focus on Application Requirements
§ Divide-and-Conquer:
§ Programmability on a per-workflow basis
§ Create layers of abstraction
§ Enable communications between layers
Required focus
Traditional focus
Programming the Edge: Abstracting Communications
§ Where are resources attached?
§ Whom can talk to whom?
§ High Rate-of-Change/Northbound Interface
§ Abstract connectivity details from resource orchestration
Static Provisioning SDN: OpenFlow
Programming the Transport: Abstracting Topology
§ Manage the “Path” of communications
– Speed-of-light, network utilization, assurance, etc.
§ Abstract path details from Connectivity Layer
Static Config SDN: BGP-TE, Stateful PCE

HOW DO WE GET THERE?
SDN is about adding new value to existing
systems and workflows
§ Enable High Rate-of-Change in the Edge
§ Decouple Abstraction Layer from Transport Layer
§ Free your equipment to add software-driven value
§ SDN value requires Bi-Directional Communication
Device Abstraction: QFabric
§ Universal Bandwidth and Connectivity
§ Manage a Single Logical Device OpenFlow
OpenStack
Other
Single Point of Programming

Requirement “MultiScale”, HA

17. Vendor Integration Challenge
- They Enable Open Flow in Switches
- We Integrate controller with Switches and our Stacks
- We Manage flow through Fabric
- If not enabled, Overlay/Tunnel through it (like MPLS today)
- - They Innovate around openvswitch and derivatives
- - We run at scale—HA-based controllers (not there yet)
- All of us ….Invent new network types

NEW NETWORKS IN HEALTHCARE
Securing all Resources through SDN Control

19. 17 Copyright © 2012 Juniper Networks, Inc. www.juniper.net
NEW TERM: “MULTISCALE”
HA, SDN Networks are in the Class of MultiScale
- First there was “Biology”
- Then there was “Systems Biology”
- Then there was “Network Biology”
- Now…the term biologists use to describe complexity is
MULTISCALE

THE INSTRUCTIONS

27. The Digital – Life Virtuous Cycle
- The more we understand biology, the better we make
TECHNOLOGY
- The better we make technology the more we can
understand BIOLOGY
- The more we apply technology to biology the better we
can LIVE
- SDN is a new, enabling technology in the cycle
