End User License Agreement

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

has paid the applicable license fees; provid ed, however, with respect to the Steel-Belted or Odyssey Access Client software only, Customer shall 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
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 cre
by re-installing the Software after the 30-day trial period.

e. The Global Enterprise Edition of the Steel-Belted software may be used by Customer only to manage access to Customer’s enterprise network.

Specifically, service provider customers are expressly prohibited from using the Global Enterprise Edition of the Steel-Belted software to support any
commercial network access services.

The foregoing license is not transferable or assignable by Customer. No license is granted herein to any user who did not originally purchase the applicable
license(s) for the Software from Juniper or an authorized Juniper reseller.

4. Use Prohibitions. Notwithstanding the foregoing, the license provided herein does not permit the Customer to, and Customer agrees not to and shall not: (a)

modify, unbundle, reverse engineer, or create derivative works based on the Software; (b) make unauthorized copies of the Software (except as necessary for
backup purposes); (c) rent, sell, transfer, or grant any rights in and to any copy of the Software, in any form, to any third party; (d) remove any proprietary notices,
labels, or marks on or in any copy of the Software or any product in which the Software is embedded; (e) distribute any copy of the Software to any third party,
including as may be embedded in Juniper equipment sold in the secondhand market; (f) use any ‘locked’ or key-restricted feature, function, service, application,
operation, or capability without first purchasing the applicable license(s) and obtaining a valid key from Juniper, even if such feature, function, service,
application, operation, or capability is enabled without a key; (g) distribute any key for the Software provided by Juniper to any third party; (h) use the Software
in any manner that extends or is broader than the uses purchased by Customer from Juniper or an authorized Juniper reseller; (i) use Embedded Software on non­Juniper equipment; (j) use Embedded Software (or make it available for use) on Juniper equipment that the Customer did not originally purchase from Juniper or
an authorized Juniper reseller; (k) disclose the results of testing or benchmarking of the Software to any third party without the prior written consent of Juniper;
or (l) use the Software in any manner other than as expressly provided herein.

5. Audit. Customer shall maintain accurate records as necessary to verify compliance with this Agreement. Upon request by Juniper, Customer shall furnish such

records to Juniper and certify its compliance with this Agreement.

6. Confidentiality. The Parties agree that aspects of the Software and associated documentation are the confidential property of Juniper. As such, Customer shall

exercise all reasonable commercial ef forts t o mai nta in t he Soft ware a nd associat e d docume ntati on in conf idence , which at a mini mum i ncludes res tri cti ng acce ss
to the Software to Customer employees and contractors having a need to use the Software for Customer’s internal business purposes.

7. Ownership. Juniper and Juniper’s licensors, respectively, retain ownership of all right, title, and interest (including copyright) in and to the Software, associated

documentation, and all copies of the Software. Nothing in this Agreement constitutes a transfer or conveyance of any right, title, or interest in the Software or
associated documentation, or a sale of the Software, associated documentation, or copies of the Software.

8. Warranty, Limitation of Liability, Disclaimer of Warranty. The warranty applicable to the Software shall be as set forth in the warranty statement that

accompanies the Software (the “Warranty Statement”). Nothing in this Agreement shall give rise to any obligation to support the Software. Support services may
be purchased separately. Any such support shall be governed by a separate, written support services agreement. TO THE MAXIMUM EXTENT PERMITTED

OR SERVICES, OR FOR ANY SPECIAL, INDIRECT, OR CONSEQUENTIAL DAMAGES ARISING OUT OF THIS AGREEMENT, THE SOFTWARE, OR
ANY JUNIPER OR JUNIPER-SUPPLIED SOFTWARE. IN NO EVENT SHALL JUNIPER BE LIABLE FOR DAMAGES ARISING FROM
UNAUTHORIZED OR IMPROPER USE OF ANY JUNIPER OR JUNIPER-SUPPLIED SOFTWARE. EXCEPT AS EXPRESSLY PROVIDED IN THE
WARRANTY STATEMENT TO THE EXTENT PERMITTED BY LAW, JUNIPER DISCLAIMS ANY AND ALL WARRANTIES IN AND TO THE
SOFTWARE (WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE), INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY,
FITNESS FOR A PARTICULAR PURPOSE, OR NONINFRINGEMENT. IN NO EVENT DOES JUNIPER WARRANT THAT THE SOFTWARE, OR ANY
EQUIPMENT OR NETWORK RUNNING THE SOFTWARE, WILL OPERATE WITHOUT ERROR OR INTERRUPTION, OR WILL BE FREE OF
VULNERABILITY TO INTRUSION OR ATTACK. In no event shall Juniper’s or its suppliers’ or licensors’ liability to Customer, whether in contract, tort
(including negligence), breach of warranty, or otherwise, exceed the price paid by Customer for the Software that gave rise to the claim, or if the Software is
embedded in another Juniper product, the price paid by Customer for such other product. Customer acknowledges and agrees that Juniper has set its prices and
entered into this Agreement in reliance upon the disclaimers of warranty and the limitations of liability set forth herein, that the same reflect an allocation of risk
between the Parties (including the risk that a contract remedy may fail of its essential purpose and cause consequential loss), and that the same form an essential
basis of the bargain between the Parties.

9. Termination. Any breach of this Agreement or failure by Customer to pay any applicable fees due shall result in automatic termination of the license granted

herein. Upon such termination, Customer shall destroy or return to Juniper all copies of the Software and related documentation in Customer’s possession or
control.

10. Taxes. All license fees payable under this agreement are exclusive of tax. Customer shall be responsible for paying Taxes arising from the purchase of the

license, or importation or use of the Software. If applicable, valid exemption documentation for each taxing jurisdiction shall be provided to Juniper prior to
invoicing, and Customer shall promptly notify Juniper if their exemption is revoked or modified. All payments made by Customer shall be net of any applicable
withholding tax. Customer will provide reasonable assistance to Juniper in connection with such withholding taxes by promptly: providing Juniper with valid
tax receipts and other required documentation showing Customer’s payment of any withholding taxes; completing appropriate applications that would reduce the
amount of withholding tax to be paid; and notifying and assisting Juniper in any audit or tax proceeding related to transactions hereunder. Customer shall comply
with all applicable tax laws and regulations, and Customer will promptly pay or reimburse Juniper for all costs and damages related to any liability incurred by
Juniper as a result of Customer’s non-compliance or delay with its responsibilities herein. Customer’s obligations under this Section sha ll surv iv e te rm in at ion or

necessary approvals. Customer shall be liable for any such violations. The version of the Software supplied to Customer may contain encryption or other
capabilities restricting Customer’s ability to export the Software without an export license.

12. Commercial Computer Software. The Software is “commercial computer software” and is provided with restricted rights. Use, duplication, or disclosure by the

United States government is subject to restrictions set forth in this Agreement and as provided in DFARS 227.7201 through 227.7202-4, FAR 12.212, FAR

27.405(b)(2), FAR 52.227-19, or FAR 52.227-14(ALT III) as applicable.

14. Third Party Software. Any licensor of Juniper whose software is embedded in the Software and any supplier of Juniper whose products or technology are

embedded in (or services are accessed by) the Software shall be a third party beneficiary with respect to this Agreement, and such licensor or vendor shall have
the right to enforce this Agreement in its own name as if it were Juniper. In addition, certain third party software may be provided with the Software and is subject
to the accompanying license(s), if any, of its respective owner(s). To the extent portions of the Software are distributed under and subject to open source licenses
obligating Juniper to make the source code for such portions publicly available (such as the GNU General Public License (“GPL”) or the GNU Library General
Public License (“LGPL”)), Juniper will make such source code portions (including Juniper modifications, as appropriate) available upon request for a period of

15. Miscellaneous. This Agreement shall be governed by the laws of the State of California without reference to its conflicts of laws principles. The provisions of the

U.N. Convention for the International Sale of Goods shall not apply to this Agreement. For any disputes arising under this Agreement, the Parties hereby consent
to the personal and exclusive jurisdiction of, and venue in, the state and federal courts within Santa Clara County, California. This Agreement constitutes the
entire and sole agreement between Juniper and the Customer with respect to the Software, and supersedes all prior and contemporaneous agreements relating to
the Software, whether oral or written (including any inconsistent terms contained in a purchase order), except that the terms of a separate written agreement
executed by an authorized Juniper representative and Customer shall govern to the extent such terms are inconsistent or conflict with terms contained herein. No
modification to this Agreement nor any waiver of any rights hereunder shall be effective unless expressly assented to in writing by the party to be charged. If any
portion of this Agreement is held invalid, the Parties agree that such invalidity shall not affect the validity of the remainder of this Agreement. This Agreement
and associated documentation has been written in the English language, and the Parties agree that the English version will govern. (For Canada: Les parties aux

Preface Media Flow Controller Administrator’s Guide

CHAPTER 1

Preface

This Administrator’s Guide is written for system and network administrators who plan,
implement, and manage video delivery environments. In addition to What’s New in Release

2.0.4, this preface includes these topics:

• Guide to This Document

• Documentation and Release Notes

• Text and Syntax Conventions

• Terminology

• Documentation Feedback

• Requesting Technical Support

What’s New in Release 2.0.4

Release 2.0.4 introduces minor feature enhancements and issue resolutions. This section
provides short descriptions of the feature enhancements in Release 2.0.4.

PXE Installation Enhancements

In Release 2.0.4, Media Flow Controller simplifies the PXE boot process by eliminating the
need for administrators to have an interactive console session to boot it. Administrators can
configure the PXE boot options at the PXE server, in the PXE configuration specification file
(PXE spec). The following new PXE boot functions are supported in Release 2.0.4:

• No need to specify an URL for PXE boot

• Option to pre-accept the End User License Agreement (EULA)

• Automatically mark the interface that was used for PXE-booting as eth0

• Ability to specify all installation options in the PXE spec so administrator does not have to

manually enter anything

See the Media Flow Controller and Media Flow Manager Installation Guide

Installations on Non-Centos Linux Drives

On fresh installations, any partition data on the drive is overwritten. Previously , if disk drives
had non-Centos data when doing a fresh installation, the installer responded with a partition
error.

for details.

Preface Media Flow Controller Administrator’s Guide

Logging Enhancements

The option to export log files at more frequent rates than every hour has been added. You ca n
now configure automatic log imports for every 5 minutes.

You can now keep log files on Media Flow Controller for up to 14 days.
Logs can now be uploaded via SFTP with SSH keys rather than sending the password in

cleartext.

Media Cache

You can now upload meta data to the media cache.
You can now list controllers on the media cache; currently 3ware controller only.
