  • Hal: edited third bullet since it overlapped fourth a bit, and focused on the tools part, which is a great point
  • Hal: I still think the “to the cloud” is misplaced. Could we play it with the centralized vs distributed control? there’s distributed (all over the net), centralized (one master brain) and then “cloud based” (it’s remote, could be either one)
  • You’re thinking you can already do this, right? But you can’t. We’re making development move up a level – by giving you access to new technologies, products and platforms that will up-level your development abilities for new applications & services. Network-Aware ApplicationsNetwork 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 NetworksReal-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.Programmable NetworksA 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.
  • Hal: this went back into data focus and running the network. I believe we need to keep that bi-drectional data up from the netowrk control down to the network flow; it’s about the closed loop. Edit what I did obviously….
  • There is a divide between IT and developers that doesn’t allow for innovation. Demands on the network drive massive scale, including increased bandwidth for content, streaming, videos, and more. Difficult to solve deep network problems, such as how to content distribution, protocol compatibility, performance, security issues, and more. Need to be able to control networks in new ways with specialized customization. Web-based organizations unable to take advantage of rigid, OOB hardware offerings. Lower barriers to entry needed for new services or offerings, whether in-house developed or from a partner or third party.Adding boxes to solve problems is not economical nor operationally efficient; Economies of scale are creating constraints that typical networking platforms cannot fix.
  • There is more out there that can be offered. Here is what you want as a developer.
  • hal: attempting marketing here
  • Hal: again, can we either merge this into the “value pillars” or into the types of apps? seems like we have five or more different views of TPN, and I think we need four: techincal, what and why; value/business what/why, for developers, what/why and customers, what/why This content should be merged into developer/business, I think.
  • Objective of this slide:One of the common fears of developers is the amount of net new investment s/he has to make on the platform. “HOW MUCH time do I have to invest in getting started here”. The Goal here is to emphasize the strengths of our SDKs – in that our SDKs come out of the box, comprehensive and enables the developers to focus on INNOVATION and NOT on the plumbing. Goal here is also to stress that we enable GTM faster and efficiently. Re-iterate 3 principles.===In the past developers are forced to create the plumbing before they can start building applications. Much time was spent and wasted in focusing heavily on the foundation aspects than the business and innovation aspects of application development.That’s the reason at Juniper we decided to take a different approach. Where Juniper Platform exposes the needed plumbing thru the SDK and APIs so developers can focus more on innovation and less on the plumbing aspects. Thereby enabling the developers to unlock and expose the network intelligence thru their applications easily, effectively and efficiently.Some of the key benefits our developers are already seeing :Faster development timeGTM quickerMore intelligent applications at a faster time. Less time on the plumbingTransition to the next slideTo summarize in one slide, you as a network developer now have the capability of building a variety of solns on our platform
  • Speaker notes and backup informationJuniper is a strong proponent of open networks & programmability and has been so for many yearsKey benefit of programmability is to enable value creation on the new network, e.g., for the creation of value added services or apps that simplify network managementExamples of Juniper’s open stance include: Juniper enables the use of 3rd party optics on Juniper products and several companies OEM Juniper products, incl. Ericsson.Juniper is also actively creating a developer ecosystem, Junos Developer Network, with over 100 partner companies signed up to dateJuniper provides unique end-to-end programmabilityStarting with on-device: JunosJunos Software Development Kit (SDK) offering programmability; OpenFlow is one of the APIs that enable programmabilityCross-device: Junos SpaceWith Space SDK to enable orchestration and management, incl. mash-ups of networking apps with non-networking appsOn the Endpoint: Junos PulseJunos Pulse available for iPhone and iPad among othersUse cases include handset and data securityOpenFlow enriches programmability of the deviceHelping make apps network-aware and networks app-awareOpenFlow adds new incremental method for programmable filter-based forwardingJuniper utilizes several mediation layers, ALTO, PCE, OF – all leveraging industry standards.As such, OF is one of many elements of network programmability and in line with Juniper’s vision for the programmable new networkFAQ:Do all Juniper products have SDKs?No, not all Juniper products have SDKs at this point in time but we plan to roll out SDKs to all platforms expanding on the MX SDK offeringPossible use cases for SDKsJunos SDK: “Embedded” apps: packet processing, proximity, data collection API examples: DMI, OpenFlow, ProximityJunos Space: widgets, content-oriented applications, network management (network data pre-processing & presentation), higher-level APIs to Junos SDK apps, workflow orchestration, etc.; mashups with non-networking appsPulse APIs: security
  • A simple example as in the case of Joulex, a partner of Juniper the goal is to enable and automate a bidirectional energy management of network assets.However there is no easy way to do this due to lack of standards.Junos Space SDK provides a clear path to Joulex to access the device energy usage uniformly and control devices intelligently.

    1. 1. For Developers: More information on Network Programmability (and how it helps you build better apps)Lauren CooneyDirector, Developer & Product MarketingJuniper Networkslcooney@juniper.net
    2. 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.Opportunities include:- Better, Smarter, & Real-time Data for your Applications- Faster Applications- New Services & Opportunities for Revenue
    3. 3. 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.

Network Programmability Redefines Software Behavior Enabling New & Integrated Solutions
    5. 5. Why Does Programmability Matter?To help make network value easily accessible to developers, and allow developers to create more intelligent & smarter applications. Network-Aware Application-Aware Programmable Applications Applications Networks Using code to make Making networkCoding to use network the network adapt to infrastructure value natively inside the needs of accessible to applications. applications developers.

    6. 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 extendanything 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 softwareplatforms, tools, technologies, and products to extract valuable network data anduse 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 throughcustomizable software, allowing for massive scalability, resource efficiencies, and unprecedented extensibility – across networks, devices, and to the cloud. Simply, Efficiently, and Cost-Effectively.
    7. 7. Why Do We Need a Programmable Network?Every IT department and enterprise has a unique combination of applications, network architecture, efficiency constraints and goals, so out out-of-the box solutions rarely fit your needs. IT and Development often live separate lives Information Developers Technology Enterprises / Customers Developers Information Telecom Technology Infrastructure Application/Network divide OSS/Network divide
    8. 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. 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, andmore take advantage of new technologies. Customers should be able to take advantage of more than just the above.
