READ THIS END USER LICENSE AGREEMENT (“AGREEMENT”) BEFORE DOWNLOADING, INSTALLING, OR USING THE SOFTWARE. BY
DOWNLOADING, INSTALLING, OR USING THE SOFTWARE OR OTHERWISE EXPRESSING YOUR AGREEMENT TO THE TERMS CONTAINED
HEREIN, YOU (AS CUSTOMER OR IF YOU ARE NOT THE CUSTOMER, AS A REPRESENTATIVE/AGENT AUTHORIZED TO BIND THE CUSTOMER)
CONSENT TO BE BOUND BY THIS AGREEMENT. IF YOU DO NOT OR CANNOT AGREE TO THE TERMS CONTAINED HEREIN, THEN (A) DO NOT
DOWNLOAD, INSTALL, OR USE THE SOFTWARE, AND (B) YOU MAY CONTACT JUNIPER NETWORKS REGARDING LICENSE TERMS.
1.The Parties. The parties to this Agreement are (i) Juniper Networks, Inc. (if the Customer’s principal office is located in the Americas) or Juniper Networks
(Cayman) Limited (if the Customer’s principal office is located outside the Americas) (such applicable entity being referred to herein as “Juniper”), and (ii) the
person or organization that originally purchased from Juniper or an authorized Juniper reseller the applicable license(s) for use of the Software (“Customer”)
(collectively, the “Parties”).
2.The Software. In this Agreement, “Software” means the program modules and features of the Juniper or Juniper-supplied software, for which Customer has paid
the applicable license or support fees to Juniper or an authorized Juniper reseller, or which was embedded by Juniper in equipment which Customer purch as ed
from Juniper or an authorized Juniper reseller. “Software” also includes updates, upgrades and new releases of such software. “Embedded Software” means
Software which Juniper has embedded in or loaded onto the Juniper equipment and any updates, upgrades, additions or replacements which are subsequently
embedded in or loaded onto the equipment.
3.License Grant. Subject to payment of the applicable fees and the limitations and restrictions set forth herein, Juniper grants to Customer a non-exclusive and
non-transferable license, without right to sublicense, to use the Software, in executable form only, subject to the following use restrictions:
a.Customer shall use Embedded Software solely as embedded in, and for execution on, Juniper equipment originally purchased by Customer from Juniper or
an authorized Juniper reseller.
b.Customer shall use the Software on a single hardware chassis having a single processing unit, or as many chassis or processing units for which Customer

use such Software on a single computer containing a single physical random access memory space and containing any number of processors. Use of the
Steel-Belted Radius or IMS AAA software on multiple computers or virtual machines (e.g., Solaris zones) requires multiple licenses, regardless of whether
such computers or virtualizations are physically contained on a single chassis.
c.Product purchase documents, paper or electronic user documentation, and/or the particular licenses purchased by Customer may specify limits to
Customer’s use of the Software. Such limits may restrict use to a maximum number of seats, registered endpoints, concurrent users, sessions, calls,
connections, subscribers, clusters, nodes, realms, devices, links, ports or transactions, or require the purchase of separate licenses to use particular features,
functionalities, services, applications, operations, or capabilities, or provide throughput, performance, configuration, bandwidth, interface, processing,
temporal, or geographical limits. In addition, such limits may restrict the use of the Software to managing certain kinds of networks or require the Software
to be used only in conjunction with other specific Software. Customer’s use of the Software shall be subject to all such limitations and purchase of all
applicable licenses.
d.For any trial copy of the Software, Customer’s right to use the Software expires 30 days after download, installation or use of the Software. Customer may
operate the Software after the 30-day trial period only if Customer pays for a license to do so. Customer may not extend or create an additional trial period

Terminology
This section provides definitions for Juniper Networks and industry-standard terms that may
be unfamiliar to the reader.
Edge cache: An appliance placed between the Internet and the Web server that caches
content (like Java Script, CSS, images, and so forth) and delivers them for the server, freeing
up the Web server for other processes. Media Flow Controller as an edge cache is effectively
a “reverse proxy” that provides these benefits: reduces the load (network and CPU) on an
origin server by servicing previously retrieved content and enhances the user experience due
to a decrease in latency.
NIC Network Interface Controller/Card.
Origin Library The source of media content.

Obtaining Software for Installation
There are two ways you can obtain the Media Flow Controller or Media Flow Manager
software for installation on generic x86 64-bit hardware from Juniper Networks Support:
•Juniper Networks ships you a CD or USB drive with the software; you can also download
an ISO image and burn a CD. This guide describes how to install from CD or USB drive.
•You use PXE (preboot execution environment) to obtain the software image. You must
have a PXE server configured in order to use the PXE installation option and a Web server
to serve the image. How to configure your PXE server for Media Flow Controller or Media
Flow Manager installation and how to install with PXE is described in this guide.
Important! This guide describes Media Flow Controller and Media Flow Manager installation
on generic x86 64-bit hardware. This guide is not intended for use with Juniper Networks
Media Flow Engine appliances on which the software is pre-installed.

CHAPTER 2 Getting StartedMedia Flow Controller and Media Flow Manager Installation Guide
Pre-installation Planning
Before installing Juniper Networks software, ensure that your hardware meets these conditions:
•Running optimally (all hardware diagnostics have been run and passed successfully).
•All data is backed up; Juniper Networks Media Flow Controller completely format all disks
when installed.
•Top-quality cables are used. We recommend CAT5e or CAT6 for GbE, CAT6A for 10GbE,
or Fiber LL cables. However, CAT5 cables can be used for GbE if the cable lengths are
expected to be short ( for example, 5 feet or less). A poorly functioning cable can inhibit
performance.
•NIC is present.
•Console server / terminal server are available (recommended).
Tip! Go to NTP Servers Web
You also need to know:
•Which physical ports you want named eth0 and eth1. This is important because eth0
(management interface) and eth1 (recommended origin-fetch interface) are usually NOT
automatically assigned to the optimal ports (non-traffic bearing); instead, you must make
this assignment as part of the installation.
to find public NTP servers.
•Hostnames/IP addresses (including but not limited to, Subnet Mask, Default Gateway) for
traffic and management ports.
•Hostnames/IP addresses for external servers such as origin servers/libraries, DNS, NTP,
logging, or storage servers.
Important! Media Flow Controller and Media Flow Manager do not support RAID arrays.
Release Installation Guidelines
This section provides information on the way Media Flow Controller works with Host Bus
Adapters/Hard Drive Controllers.
Host Bus Adapter / Hard Drive Controller
Media Flow Controller does not natively support RAID of any kind on any hard drive or
combination of hard drives. We recommend that ALL hard disk drives (HDDs) are configured
in "Just a Bunch of Disks" (JBOD) mode with write-cache disabled, regardless of controller
battery.
At initialization, Media Flow Controller attempts to uniquely identify each HDD by its
manufacturer-given serial number. This allows caches, the physical disks to which Media Flow
Controller writes cached data, to be removed and reinserted into a system without data loss or
the need to re-initialize. Also, because Media Flow Controller is able to uniquely identify
caches, they may be transferred to to another Media Flow Controller (removed from one
physical server and inserted in another running the same version of Media Flow Controller).
This lets you hot-swap caches for either new HDDs (provided the controller supports
hot-swap) or existing caches—without interrupting content delivery or restarting Media Flow
Controller.
