A key benefit of using Junos OS is lower TCO as a result of reduced operational challenges and improved operational<br />
productivity at all levels in the network.<br />

Figure 8: Junos OS lowers operations costs across the data center<br />
An independent commissioned study conducted by Forrester Consulting3 (www.juniper.net/us/en/reports/junos_tei.pdf)<br />
found that the use of Junos OS and <strong>Juniper</strong> platforms produced a 41% reduction in overall operations costs for network<br />
operational tasks including planning and provisioning, deployment, and planned and unplanned network events.<br />
<strong>Juniper</strong> Platform Overview<br />
The ability to migrate from a three-tier network design to a simpler two-tier design with increased performance,<br />
scalability, and simplicity is predicated on the availability of hardware-based services found in networking platforms<br />
such as the EX Series Ethernet Switches, MX Series 3D Universal Edge Routers, and the SRX Series Services Gateways.<br />
A consistent and unified view of the data center, campus, and branch office networks is provided by <strong>Juniper</strong>’s “single<br />
pane of glass” management platforms, including the recently introduced Junos Space.<br />
The following section provides a brief overview of the capabilities of <strong>Juniper</strong>’s platforms. All of the Junos OS-based<br />
platforms highlighted provide feature consistency throughout the data center <strong>LAN</strong> and lower TCO.<br />

Typically deployed at the access layer in a data center, <strong>Juniper</strong> <strong>Networks</strong> EX4200 Ethernet Switch provides chassisclass,<br />
high availability features, and high-performance throughput in a pay as you grow 1 rack unit (1 U) switch.<br />
Depending on the size of the data center, the EX4200 may also be deployed at the aggregation layer. Offering flexible<br />
cabling options, the EX4200 can be located at the top of a rack or end of a row. There are several different port<br />
configurations available with each EX4200 switch, providing up to 48 wire-speed, non-blocking, 10/100/1000 ports<br />
with full or partial Power over Ethernet (PoE). Despite its small size, this high-performance switch also offers multiple<br />
GbE or 10Gbe uplinks to the core, eliminating the need for an aggregation layer. And because of its small size, it takes<br />
less space, requires less power and cooling, and it costs less to deploy and maintain sparing.<br />
Up to 10 EX4200 line switches can be connected, configured, and managed as one single logical device through built-in<br />
Virtual Chassis technology. The actual number deployed in a single Virtual Chassis instance depends upon the physical<br />
layout of your data center and the nature of your traffic. Connected via a 128 Gbps backplane, a Virtual Chassis can be<br />
comprised of EX4200 switches within a rack or row, or it can use a 10GbE connection anywhere within a data center or<br />
across data centers up to 40 km apart.<br />
