To address these challenges, Juniper isintroducing the EX9200 line of modular Ethernet core switches for campus and data center environments. The EX9200 addresses the challenges of supporting cloud applications, server virtualization, rich media collaboration tools, and of coping with the explosive growth of mobile devices by dramatically simplifying the network architecture and network operations.The EX9200 is programmable, flexible and scalable, making it well suited for both campus and data center core and aggregation environments. In fact, the EX9200 provides programmability at the silicon, system and networking layers.The EX9200’s programmability, coupled with its flexibility, scalability and carrier-class availability, allow it to dramatically simplify network architectures and operations, making it the best core and aggregation switch for the next decade.[click]
Three EX9200 switch models are available:The 4-slot EX9204The 8-slot EX9208 The 14-slot EX9214All EX9200 chassis are built on Juniper One custom silicon, the same silicon used in our industry-leading routers. All EX9200 switches also run Juniper’s Junos OS operating system. 1GbE (copper and fiber), 10GbE and 40GbE interface cards are available today; a 100GbE interface card is in development. Any combination of interface cards can be used in each of the EX9200 chassis.The key values of the EX9200 include programmability, flexibility and scalability.Programmability: The EX9200 is built on Juniper One custom silicon, a programmable ASIC featuring programmable control and management planes that allow Juniper to support new networking protocols such as VxLAN through a simple software update. Programmability extends beyond the silicon to the entire system, which supports automation capabilities to make it ready for SDN.Flexibility: The EX9200 has been optimized for both campus and data center core and aggregation environments, making it extremely flexible. The EX9200 can collapse network layers to simplify network architectures and operations. Future ready protocol support can be extended to include new protocols through simple software updates. The EX9200’s rich feature set includes:Network segmentation using MPLS, where one network can offer multiple segregated servicesConfiguration roll-backIn-service software updates In addition – the EX9200 is capable of hosting Juniper’s Virtual Wireless controller to integrate the abstracts the underlying hardware that runs wireless control servicesScalability: The system also provides the logical scale required to support any enterprise environment, including multi-tenancy and high volume VM and VDI deployments. The EX9200 scales to support more than 1 million MAC addresses, 256,000 IPv4 routes, 256,000 IPv6 routes, and 32,000 VLANs. The chassis capacity is up to 13.2 Tbps. The EX9200 lines provides five 9s of carrier-class platform availability and resiliency, plus sub-50 msec convergence to protect mission-critical data, voice and video experience following link failures.

Enterprise networks are often viewed as impediments to business agility. It takes time to re-provision networks to support new virtual machines and applications. Changes are inherently risky and are vulnerable to human errors that can take your business down. The EX9200 addresses these challenges through programmability. In fact, the EX9200 is the most programmable core switch on the market.Programmability is implemented at the silicon, system and network levels. The EX9200 is built on the Juniper One custom silicon, or ASIC—the same ASIC used in Juniper’s proven and field-tested routing platforms. The EX9200 is the first product in its class to be built on a programmable ASIC, enabling Juniper to modify the ASIC’s behavior down to the Packet Forwarding Engine (PFE) and allowing support for new networking protocols such as VxLAN to be implemented via a simple software upgrade rather than a cumbersome hardware replacement. At the system level, EX9200 platforms support Junos Automation and the Junos SDK. The switches also provide the ability to support native interfaces for SDN automation tools such as Juniper’s Contrail , Puppet, OpenFlow and others. This level of programmability and automation reduces the time it takes to re-provision the network to support new applications from days or weeks to seconds while virtually eliminating “human risk.” At a softwarelevel, the EX9200 supports integration with leading orchestration applications such as VMWare and OpenStack, eliminating delays and errors caused by re-provisioning the network to support virtual machine or application mobility.[click]
Most switches use “Merchant Silicon” composed of off-the-shelf chip components for their Packet Forwarding Engines—the chipset that switches and routes individual packets. Built for the masses, Merchant Silicon restricts network product manufacturers’ ability innovate since they are limited by the capabilities of the chip. Delivering basic and advanced Layer 2 switching capabilities and some basic Layer 3 switching / routing capabilities such as MPLS, Merchant Silicon has its place in the market, supporting higher volume / lower cost platforms such as access switches.A core switch based on Merchant Silicon, however, cannot deliver business agility. Today’s core switches require advanced Layer 3 and deep buffering capabilities. Furthermore, business agility requires advanced MPLS and Overlay Gateway Routing capabilities, as well as the ability to support future, still evolving capabilities without requiring hardware replacements.[Click]Most important, Packet Forwarding Engines need to deliver all capabilities “at scale,” whether to one device or to hundreds of thousands. Capabilities cannot be sacrificed at the expense of scale.Juniper’s programmable ASIC is ready to support any network for at least the next 10 years.[Click]NOTE: Examples of vendors using Merchant vs Custom SiliconMerchant Silicon: Arista, HuwaiiCustom Silicon: Brocade, CiscoProgrammable Custom Silicon: Juniper
