Junos Operating System HighlightsSlide 7IntroductionThe Junos operating system is a single network operating systemintegrating routing, switching, security, and servicesJunos OS delivers the power of one operating system to runhigh-performance networking infrastructureThe Junos OS command-line interface offers specialized featuresto save time for users and prevent downtime in the networkJuniper offers customers the training, tools, and services neededto make the adoption of Junos OS simple and safe 2011 Juniper Networks, Inc. All rights reserved.CONFIDENTIALSSFJUN01Gwww.juniper.net 7Much of the value, the savings, and the streamlining of operations of our products and solutions aredelivered by the Junos operating system.With the limited amount of time that you have to talk to customers and get their interest, it’s important tounderstand how the operating system works, how customers use it, and how you can help to ease itsadoption into their own infrastructure. When we talk about Junos, we talk about the Junos advantageoffered by the Power of One operating system.This course is designed to share with you the highlights of the Junos advantages, focusing on its keydifferences and ease of operation that would aid to lower your customers operating costs. The courseprovides operational and configurational commands, illustrating the power of Junos and its ease of use.SSFJUN01-I Juniper Networks, Inc.8

Junos Operating System HighlightsSlide 8Why Is Juniper Different? 2011 Juniper Networks, Inc. All rights reserved.CONFIDENTIALSSFJUN01Gwww.juniper.net13 8Juniper Networks has always thought differently about the network. Whereas our competitors havetrended towards a box-on-box, multiple operating system approach; Juniper sees that this leads to spiralinglayers of complexity in customer networks.We have purposely driven our strategy to simplify the network through specific investment and newdevelopment looking towards convergence. Over more than a decade Juniper has evolved Junos softwareas a single, end-to-end, high-performance operating platform of the network to deliver routing, switching,security, services and cloud. This approach in how we innovate is fundamentally different than ourcompetitors enabling our customers to build their networks and deliver new services in converged offeringswith simplicity of operations and reduced costs.SSFJUN01-I Juniper Networks, Inc.9

Junos Operating System HighlightsSlide 9How Competitors Manage the Complexity 2011 Juniper Networks, Inc. All rights reserved.CONFIDENTIALSSFJUN01Gwww.juniper.net 9The legacy networking providers approach has been hardware oriented. Sell another box to fix anotherproblem. As these vendors acquire companies and add more products they are also adding more operatingsystems, more proprietary software, more complexity, and more problems.Complexity is their strategy! They’ll sell more boxes. The customer must pay for a lot of services andsupport to integrate and make it all work.But this puts the customer in a constant state of upgrading, testing, and maintaining. The operating systemsmay need to be individually tailored, and it is unknown how changes, bugs, and upgrades on one box willaffect the others. More boxes get sold to attempt to fix problems, but complexity and cost increases, whilecustomer satisfaction decreases. The bottom line for customers? Chronic complexity management.SSFJUN01-I Juniper Networks, Inc.10

Junos Operating System HighlightsSlide 10Junos: A Universal Language A consistent user experience A complete, layered operating platform from client to cloud For routing, switching, security and services Scales up and down Open programming interfaces and automation 2011 Juniper Networks, Inc. All rights reserved.CONFIDENTIALSSFJUN01Gwww.juniper.net 10Junos provides a simpler approach with fewer issues. When talking about Junos to customers, partners,etc., we need to think outside of the normal “box” conversation. The discussion needs to be more aboutselling a solution rather than just another box. Junos software is changing the way we should be looking atthe whole network experience.As we stated earlier, Junos is much more than an operating system; it is a simplified, common language thatprovides a consistent user experience across multiple devices. With Junos you get consistent corefunctionality that scales from the smallest to the largest device on the network.It is based on open standards so it integrates seamlessly into the network, even with our competitorsproducts. Customers can move, over time, to a network with fewer problems and lower cost.SSFJUN01-I Juniper Networks, Inc.11

Junos Operating System HighlightsSlide 11An Open Platform Approach 2011 Juniper Networks, Inc. All rights reserved.CONFIDENTIALSSFJUN01Gwww.juniper.net 11Thinking “boxes first” limits your design perspective.Rather than being about bottoms up deployment of boxes, migrating to the open platform approach ofJunos takes customers to a new way of network design. The layered, converged platform approach ofJuniper is about looking at the network as a whole from the top-down perspective of customer needs.Providing a platform approach based on layers of silicon, system, and software, allows Juniper to deliver acomplete solution supporting many applications. With Juniper’s focus on innovation in software running onsilicon and systems layers built with the headroom capacity for innovation, customers can meet many newrequirements for new services delivery through the flexibility and lower costs of software changes alone.Moreover, Juniper opens the door to third party innovation and integration by offering a set of Junossoftware development kits to partners so they can release even more value from their network.SSFJUN01-I Juniper Networks, Inc.12

All rights reserved.CONFIDENTIALSSFJUN01Gwww.juniper.net 12Multiple components of the Junos software platform give developers unmatched flexibility to createdynamic applications that interact with the network from the client to the cloud.- In the network, the open standards, open platform approach of the operating system inspires innovation.-Junos Space is a programmable platform for developing and running applications across the network.-And Junos Pulse is a multi-service network client that can be used on mobile devices such as notebooks,netbooks, and smartphones. It too is a open, programmable, platform that simplifies the end userexperience.-Running over these platform layers is a growing portfolio of Junos Ready Software applications developedby Juniper and third-parties.SSFJUN01-I Juniper Networks, Inc.13

Junos Operating System HighlightsSlide 13Difference of One Junos 2011 Juniper Networks, Inc. All rights reserved.CONFIDENTIALSSFJUN01Gwww.juniper.net 13The foundational component of the Junos software platform is the Junos operating system. Running a singleoperating system across devices makes the day-to-day operation of the network less complex. The IT staffcan focus on rolling out new deployments and maintaining the network, making better use of their timeand effort. With a steady release of new features and a modular architecture they have predictableperformance and the ability to streamline their tasks through automation. They can evolve their currentnetwork infrastructure rather than adding box on top of box.This provides a consistent user experience for the IT staff and lower costs for the customer.SSFJUN01-I Juniper Networks, Inc.14

Junos Operating System HighlightsSlide 14Junos OS Separate Control and ForwardingSupports scale for highperformanceAssures performance of eachplane 2011 Juniper Networks, Inc. All rights reserved.Control PlaneProvides options forredundancyRoutingEngineData PlaneEnhances 01Gwww.juniper.net 14Let’s review some of the architecture highlights – what’s different in the design. From the beginning theengineers decided to separate the functions of control and forwarding. Ask yourself a question – what dorouters do for living? They determine the path and then, once they know the next hop, they switch packets.So, it makes complete logical sense to separate the function of path determination, or control, from thefunction switching, or packet forwarding.Think of control as the brains of the system. It’s really what runs the protocols. The forwarding is where thepacket handling happens. It’s the brawn of the system. It’s what’s responsible for the high throughput –taking packets, inspecting them, and moving them on quickly down the network.So, if you’re not a software engineer, why do you care about this? Well, the bottom line here is - dedicatedresources means high resiliency, which gives you that incredibly high availability that carriers rely on. So,again, carrier class is what we’ve got.SSFJUN01-I Juniper Networks, Inc.15
