Notes de l'éditeur
- applications tell networks their requirements, resources, constraints, security rulesnetworks tell applications how to optimize, run more efficiently, handle exceptions
- applications tell networks their requirements, resources, constraints, security rulesnetworks tell applications how to optimize, run more efficiently, handle exceptions
- It is possible both to ask questions about specific endpoints, and to request bulk map data for further processing, depending on application needs.
- there’s more data, and more reason and drive to use it, which means more network-centric or network-aware applications
- how do you change the coase-driven economics?
- 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
- james gosling, on his nighthacks website – something he has said since 1995, and is true 15 years onpeople writing enterprise applications will eventually run into these, intentionally or not (usually not)when they do, the opportunity exists for the network to highlight, announce and help redress the problem.that’s what my group does at juniper networksreliability a function of internal and external factors – congestion, DDOS are “failures”latency is 30 msec US-europe. can’t make it less. bandwidth may go up but the first byte is still sloweveryone ignores them, assuming they are not constraints. come back at scale, or criticality, to bite younetwork engineering and awareness has to be part of any data-centric IT focus.
- A couple of examples, some of which will be featured in our demos today
- Consider a closed loop system that is often used to describe how a company works. Consider the same model in the context of a network. The network infrastructure in terms of the networking devices like routers, switches, security devices combined with the entities that they connect that include the printers, servers, databases, applications form the assets in our model. Typical actions that are taken to affect these assets include permanent actions such as configuration of these devices and provisioning of services in response to customer orders. There could also be dynamic actions such as QoS policy provisioning to ensure sufficient bandwidth during a video streaming event. This is classis network management and there are several systems that offer this capability including Junos Space.What is the major paint point for a developer?Major pain point is that inhibits several developers in doing anything worthwhile beyond the realm of network management is is lack of ability with a platform that can marry the action and asset side of the cycle based on the data that is generated by the asset. Network assets generate a lot of data. This includes fairly static data such as the inventory and configuration of the network, historical information such as logs, and dynamic real-time data such as flow records. All this data by itself is worthless unless you can turn it into value by understanding what it means in the business context and what it might do operationally for the company. What is the solution?What would be useful is if the platform can provide the capability to perform analysis by filtering, collecting and correlating this data with external sources such as real time traffic, weather patterns, click behavior, financial markets etc. For example, the right insight into the data generated from the network when combined with data from external sources could yield a wealth of valuable information about subscribers - who they are, where they are, how often they connect, where they connect from, the duration of usage, the type of services they use, the frequency of these services, their credit profile, etc. This insight will generate intelligent actions – both permanent as well as dynamic – which will tune the networking assets to operate more efficiently as well as generate more value for the company.How does Junos Space and the SDK change the equation in favor of an application innovator?Where Junos Space changes the equation is to marry the Action and Asset side of the cycle on the left with the Data and Value side on the right. It provides the ability to suck in the static and dynamic behavior of the network and analyze this behavior in the context that can be provided by an internal or an external source. The internal source could be an event on the network itself and the external source (as mentioned before) could be some business intelligence or a truly external entity in the form of weather patterns or user behavior etc. Space combines the ability to access the static and the dynamic nature and the wealth of information hidden in them with the ability to combine this data with an internal or an external source. This combined with a highly scalable and resilient platform and a great set of tools that allow developers to easily utilize the wealth information makes Space and Space SDK a great platform to develop the new and the next generation applications.
- Joulex is an external application using the JUNOS Space API to collect Energy information for Junos Space managed devices.It collects Power information by executing Junos XML RPCs on Junos Space discovered devices.Underpinned by an open, standards-based, integrateddevelopment environment (IDE), Junos Space SDK provides arich development environment which includes a RESTful Webservices API, the Junos Space platform, built-in device simulators,documentation, reference applications, and support tools. JunosSpace SDK reduces the complexity of building a broad range ofinnovative applications and services on enterprise and serviceprovider networks.Using Junos Space SDK, JouleX was able to extend the reach anddepth of JEM to deliver energy consumption reductions of 30% to60%.1. JEM remotely queries each Juniper device using Junos SpaceSDK for the current energy consumption and utilization.2. JEM builds historical utilization data for an accurate energy useprofile for each device and in aggregation.
- Objective of this slide:Showcase various partners taking advantage of our platform. Why they are betting on our platform. And HOW they are seeing the value of our 3 principles in their own solns by relying on Juniper. speak to that we want the audience names to show there eventually w/ their solns.===We’d like to see your name up here and your applications in our marketplace and would love to hear what you can do with and on our platform. We are here to help, we are here to jointly work w/ you in making YOU successful on our platform. Transition to next slide:Before, I close this session…I would like to leave you w/ a few call to actions…
