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.
Opportunities include:
Better, Smarter, & Real-time Data for your Applications
Faster Applications
New Services & Opportunities for Revenue

Challenges Overshadow Opportunities
-Increased Opex Costs & Reduced Budget
- Software offerings fragmented & stuck in organizational silos; limited access to network data.
- Lack of developer tools accessible to many limits innovation at the network level; hardware companies not able to make products for specific web-based companies.
- Revenue opportunity creation complex & not easy to integrate into existing infrastructures.

Juniper’s New Network Is Programmable
Network Programmability
Network-Aware Applications
Network visibility in an application or delivery service used to build enhancements. Focus is on location of the end user and proximity to the server/cache. Examples include services for network performance management, WAN Optimization, customer experience management, content filtering, and internal billing of networked applications.
Application-Aware Networks
Real-time data capture and extraction & correlation of information from the network to be used in applications, services, & solutions. Allows for new service topologies, new paths, ability to dilate or constrict bandwidth on a link, path, take preventive measures and protect network assets in real time. Allows developer to create better services such as Bandwidth & Resource Optimization, Quality of Service (QoS), Content-Based Billing, Quality of Experience (QoE), VoIP Fraud Monitoring and Regulatory Compliance.
Programmability
A networking device with a published set of APIs or SDK that is enabled with standardized protocols allowing Applications to program the forwarding, control or management plane of the device. Include orchestration (OSS/BSS), Routing Signaling Activity, Analytics, and Perimeter Service Control.

Programmable Networks
New Opportunities for Developers
Future Innovation
Language independent, scalable and accessible to the general purpose developer: meet disruption where it happens
New Standards & Protocols

Programmable Perimeters
Security, services, devices: make them more functional, flexible, and valuable through data flow intelligence.
Open Data Access
Get data about network flows, users, applications, and network topologies to inform applications, and have applications inform the network
Intelligent. Open. Efficient.
Programmability allows for developer customization and provides services & solutions enabling flexible business models and innovative service delivery.

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.

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

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.

The Programmable Network Enables:
New business models
New revenue-generating services
Faster movement to scale and control data & applications
Software to provide massive cost-savings
Programmability gives developers the keys to jump-start innovation (along with directions to drive it), at all levels, with all the tools, platforms & products they need to be successful.

New Ideas, New Technology: What You Need to Know
OpenFlow: takes network information & 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)

More Benefits ofNetwork Programmability

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.

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.

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.

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.
