2. Why Should I Care?
Programmability allows you use software to change the behavior of
the existing box, rather than adding additional equipment to your
network. You are no longer limited to the imagination of the
network equipment vendor, you are free to innovate and extend
anything you can imagine.
For Developers, you can now take advantage of rich data that was
previously trapped within the network. With programmability the
power of creation belongs to you.

6. Programmability Changes how the
Networks Works
The New Network is Programmable.
The New Network allows you use software to change the behavior of the existing box,
rather than adding additional equipment to your network. You are no longer limited to the
imagination of the network equipment vendor, you are free to innovate and extend
anything you can imagine. With programmability implemented in your network the power
of creation belongs to you.
The only way to make your network more intelligent is to give you great software
platforms, tools, technologies, and products to extract valuable network data and
use it to optimize your network’s operation. You can build amazing software that
helps you run your network better than ever before.
The Programmable Network drastically changes network economics through
customizable software, allowing for massive scalability, resource efficiencies, and
unprecedented extensibility – across networks, devices, and to the cloud.
Simply, Efficiently, and Cost-Effectively.

7. Why Do We Need a Programmable Network?

8. Programmable Networks
Solve This
Innovation needs to sit inside your organization. Juniper
makes that a reality by providing the tools, technologies &
products you trust with a
Software platform that offers:
• New architectures, new tools & new approaches that define the Network.
• A network platform that is application-aware, allowing for the network to be
controlled, optimized and informed by applications.
• Allowing developers to create the software (network-aware applications) that
utilize the network optimally, rather than the vendor providing custom-fit
software.
• The ability to extend this to program to devices through data flow intelligence.
Network Programmability allow the fine-tuning & control that customers want,
with the decoupling of software from systems that developers desire.

9. Current Network Application Capabilities
• Allows Flexibility of Service Placement
– Place your services where you want, not necessarily where the user is
physically connected
• Control of Resources from Applications
– Customize network behavior to better meet user/application needs
– Introduce non-configured device behavior changes: ephemeral
classifiers
• Lowering of operational barriers
– Decrease dependency on the traditional provisioning workflow
– Enable automation and dynamic adaptability within constraints
Juniper is extending this to help customers, partners, developers, and
more take advantage of new technologies. Customers should be able to
take advantage of more than just the above.

13. Open Data Access
Network-Aware Applications
• Extraction of data from the network with massively simplified tools to define policy,
communication methods (protocols), resource optimization, control data and more in the
form of Applications.
• Creating resources for developers with REST APIs, exposing resources for manipulation
(persisted, cached, copied, queried, and more).
• Control of resources from applications including:
•Customization of network behavior to better meet user/application needs
•Introduce non-configured (ephemeral) device behavior changes.
• Juniper is putting APIs on services, and our services go deeper into the network
elements, giving network operators a level of inspection and control that’s highly valuable
– down to the network flow or packet level.
•By extending this abstraction from the single network element to an entire network
with the programmable network platform it enables developers to go deep into
networking stack and focus on their value add without the need to know intricacies
of networking hardware and protocols.

14. Programmable Perimeters
Ability to simply program to new devices through new
methods.
• The perimeter is no longer defined by devices, but by APIs and interfaces.
• Programmable Device plays open up much richer off-network element computation
as part of the network processing.
•Flexibility of service placement
• Place your services where you want, not necessarily where the user or service
client is physically connected.
• Control of resources from applications
• Customize network behavior to better meet user/application needs
Introduce non-configured device behavior changes: ephemeral classifiers
• Lowering of operational barriers
•Decrease dependency on the traditional provisioning workflow
• Static configurations are maintenance heavy & expensive to change
• Enable automation and dynamic adaptability within constraints

15. New Standards & Protocols:
Application-Aware Networks
• Scalable infrastructure able to influence and adapt to applications, content and
end-users
• Enables new business models
• Enables continuous service adjustment between the customer & operator
• Makes network more relevant to applications, content & end-users
• Enables in-network placement of applications & content
• Simplifies interfacing with network entities
• Communicates to application how fast it can/should run
• Triangulates content, distance, and utilization for end-user.
• Traditional network models are defined by a north/south operational model,
while the programmable network expands applications east/west, allowing new
services to be inserted and monetized with finer-grain control over flows between
service and network elements.

16. Future Innovation
Limitless Opportunities
The Programmable Network Enables:
•New business models
• New revenue-generating services
•Faster movement to scale and control data & applications

exposes it to make new things possible;
selecting traffic to “steer”
• ALTO – location (where is my app in the
network?)
• PCE – what’s the best path for my application
to use across the network?
• BGP-TE – let me balance traffic across that
path (get my app there the best way possible)

28. More Benefits of
Network Programmability

29. Intelligent:
Network Data-Driven Intelligence Unlocked
•New services can be created and inserted into the transactional and data flows of the
network and stimulate a shift equivalent to that of building websites on application servers
rather than static content servers.
• Extraction of data from the network to define policy, communication methods (protocols),
resource optimization, and more.
• Ability to alter, simplify, and scale network paths and protocols not only to systems but to
the cloud – via simple to use software tools.
• Juniper has created massively simplified tools to extract data from the network for
changes to policy, communication methods, control, security, and more.
• Juniper is putting APIs on services, and our services go deeper into the network
elements, giving network operators a level of inspection and control that’s highly valuable.
By extending this abstraction from the single network element to an entire network with the
programmable network platform it enables developers to go deep into networking stack and
focus on their value add without the need to know intricacies of networking hardware and
protocols.

30. Open:
APIs and New Protocols provide development
opportunities
• Simple & Powerful APIs: Elimination of information & hardware silos, allowing the
ability to communicate with different systems and servers that were previously
unavailable.
• Data about consumption, users, subscribers, flows and policies is available -
created, annotated, and aggregated across every single point at which the network
comes into contact with a customer, employee or partner.
• The ultimate “social media” play for businesses that thrive on the economics of
their own expertise, content and services – the value is conveyed in the graph of data
exposed.
• The network has to be extendable in terms of services, their location, and the
optimization of resources to deliver them.
• Visibility: Exposing Network elements and allowing insight into formerly closed
systems.

31. Efficient:
Software Scalability & Performance Optimization
with Cost-savings
• Easy to use OpenAPIs and North/South-bound interfaces for connectivity to a multitude
of devices
•User experience, resource optimization and efficiency are delivered through the fine-
grain control of network elements to effect service placement, path engineering, and
policy decisions.
• Far from the fixed function, cost-driven component of the data center, the
programmable network is the dominant term in defining IT value. Everything from
central office to data center to mobile device is connected to one or more networks.
• Identify cost savings or operational improvements based on network element,
subscriber and flow data. Applications that improve the security, policy enforcement or
end to end reliability of the network are other efficiency-driven models.
• Integration of core functions to increase performance. Drastically Reduce number of
network elements and the number of control points into the network.

32. Extensible:
Programmable Networks are limitless, and allow you to
innovate & plan for the future.
• The programmable network approach adds unique value propositions for Juniper
and our customers: the creation of new services, the ability to insert services at
multiple points in the data or control paths of the network, and the ability to open
these entry points to Juniper’s and our customers’ software and services partners.
• There is a further multiplicative effect when third parties can insert and leverage
network services.
• Opportunities for customers and partners to create revenue-generating services
with the programmable network – from subscriber-centric services to in-depth
services specific to each customer needs.
