1.1 About the 10G Software Probe

1.1.1 VB330-SW – Overview

The VB330-SW 10G Software Probe was made specifically for IPTV backbone network monitoring.
With support for 10 Gbit/s Ethernet inputs, the 10G Software Probe provides detailed IP packet

monitoring of a very high number of Ethernet streams, suitable for core networks carrying extreme
amounts of media signals.

The OTT software option is available on the VB330-SW and enables monitoring of up to 500

adaptive bitrate channels in steps of 5 or 50 (Bulk OTT option) OTT engines depending on licensing.

A built-in web server in the VB330-SW allows remote signal monitoring using a standard web

browser. This can be managed either through a separate Ethernet network, or by using the regular

video/data network – both IPv4 and IPv6 are supported.

The VB330-SW 10G Software Probe can also be managed via the VideoBRIDGE Controller.
The VideoBRIDGE Controller will add management features like alarm aggregation and report

functionality.

The 10G Software Probe is a server appliance, that can be installed onto any server that meets

the minimum requirements specified in chapter 3.

1.1.2 10G Software Probe – Functionality

An IP-based network is fully transparent with respect to signal contents quality, provided that the IP

packets arrive, and provided that they arrive in time. The 10G Software Probe therefore uses the

8 VB330-SW 10G Software Probe User’s Manual version 5.5

patented MediaWindow to allow monitoring at-a-glance of packet loss and errors in inter-packet
arrival time. This way the operator can conveniently ensure correct signal quality at IP-level.

The advanced Ethernet protocol analysis tool automatically detects all protocols carried over Ethernet

past the port the 10G Software Probe is connected to, and it displays statistics like percentage
utilization of the interface and percentage of the different transported protocols. This gives the 10G
Software Probe a real-time sniffer capability.

The 10G Software Probe allows the user to define a Return Data Path (RDP), using the regular
video/data network or the management network to return a stream. A faulty signal can then be

further analyzed at the studio premises, when necessary.

The recording functionality allows the user to record a stream, either triggered manually by the user

or triggered by a user defined alarm.

Full Service Monitoring (FSM) checks that vital system components like CA-servers are active.

Optional Ethernet TR 290 monitoring allows the operator to check parameters like transport stream
sync and PSI/SI standards conformity. This option also performs further PSI/SI analysis, making it
possible to view PSI/SI contents. PID and service bitrates are also continuously measured.

Optional OTT monitoring allows the operator to set up active testing of Over-the-top type signals
as found in adaptive bitrate streaming architectures. Formats supported include Apple™HLS,
Microsoft ™ Smoothstream, RTMP, MPEG DASH, Adobe ™ HDS and Nullsoft SHOUTcast™.

The 10G Software Probe can be expanded through license options to monitor the T2MI protocol

layer as found in DVB-T2 networks.

VB330-SW 10G Software Probe User’s Manual version 5.5 9

The 10G Software Probe can also be licensed with an SCTE 35 option that allows monitoring and

logging of splice time codes embedded in the transport streams.

1.2 How to Use This Manual

2 PRINCIPLE OF OPERATION

The VB330-SW 10G Software Probe can utilize all the network interfaces on the host system. The

user selects which interface to be used by the monitoring engine. Management of the 10G Software
Probe is configured in the operating system web server setup1.

Figure 2.1: The VB330-SW Software – Principle of Operation

A simplified diagram of the alarm handling mechanisms of the 10G Software Probe is shown in

figure 2.2. The input signals are continuously analyzed, and measured data are checked against
user defined threshold values. If the data do not comply with the threshold values alarms will be
generated. The overall alarm settings further make it possible to enable and disable alarms, thus
defining which alarms should be reported in the 10G Software Probe alarm list and sent as SNMP
traps to an external management system.

3 INSTALLATION AND INITIAL SETUP

3.1 System Requirements

The minimum hardware requirements for virtualized or natively running Software Probe with

performance similar to or better than VB330:

• Intel XEON D-1537 1.7 GHz, 12 Mbyte Cache, 8 cores

• 8 Gbyte RAM

• 100 Gbyte HDD

• 10 Gbit/s Network Interface card for data: Intel X550/X552/X557

•

Additional 10/100/1000T Ethernet Network Interface card with support for CentOS Linux 7
or Red Hat Enterprise Linux 7 for management

•

Note that there are motherboards with the 10Gbit/s NICs referred to above built-in. The
XEON D family of CPUs has built-in support for these 10 Gbit/s NICs.

The Software Probe can be license upgraded to a higher bitrate independently of the hardware. It

may thus be useful to obtain better hardware which allows for future license upgrade.

release.

3.2 First-time Installation

Make sure that the server hardware matches the requirements listed above and then follow the
procedure outlined below.

1. Obtain the latest installation kickstart image from Sencore.

Installation media is provided both for CentOS Linux and Red Hat Enterprise Linux. If you
install the Red Hat Enterprise Linux version, you will need an active subscription for Red Hat
Enterprise Linux server.

2. Insert the installation medium into the server:

•

For DVD-based installations, burn the downloaded ISO image to a DVD and insert into
the server.

•

For USB-based installation, transfer the downloaded image to a USB mass storage device
using a tool such as dd (Mac, Unix, Linux) or USBWriter1(Windows).

•

For installation in a virtualized environment, attach the downloaded ISO image to a
virtual DVD-ROM unit.

Note:

Please read the advice on how to configure the virtual machine in section 3.3 to

ensure optimal performance.

3.

Boot the server and make sure that the primary boot device is set appropriately. If the system
fails to boot from the medium, you may need to configure the boot loader for ‘legacy BIOS
mode’.

4.

The installer will run, please follow the on-screen prompts to install the system, taking note of
the following:

• IMPORTANT: Leave ‘Software selection’ at ‘Custom software selected’.

• IMPORTANT:

large

/home

In the ‘Installation Destination’, the default partitioning will create a

partition, which is unused. To avoid this, use the ‘I will configure partitioning’
option. Then use the ‘Click here to create them automatically’ and manually reduce the
size of (or remove) the /home partition, instead giving that space to the / partition.

14 VB330-SW 10G Software Probe User’s Manual version 5.5

• We recommend that you configure network settings (IP address, gateway, DNS) within

the installer. Post-installation network configuration can be performed using the nmtui
utility, please refer to D Appendix: Network configuration for details.

•

The default installation does not provide any graphical user interface environment. This
can be installed later if desired, please refer to the CentOS Linux2or Red Hat Enterprise
Linux3documentation for more details.

5.

At the end of the installation procedure, the server is rebooted. Remove the installation media
and ensure that the system boots up properly.

6.

If you installed the Red Hat Enterprise Linux server flavor, make sure you follow the instruc­tions on how to subscribe the system to the Red Hat Customer Portal4.

If you install the CentOS Linux flavor, you may want to enable the Continuous Release
repository5to be able to get access to security updates as quickly as possible.

7.

Enter the selected IP address in your web browser to access the Software Activation page. If
your host is using dynamic addressing, you can log in to the account created during installation
and issue the command ip addr to display the address assigned to the system.

Continue to chapter 3.4 for details on how to enable the 10G Software Probe system.

The kickstart will install CentOS Linux 7 or Red Hat Enterprise Linux 7 on the server. The
disks will be formatted and all contents lost. Make sure that any important data on the server
has been backed up before beginning the procedure.

3.3 Deploying in a Virtualized Environment

It is also possible to deploy the software in a virtualized environment. For optimal performance,
check the processor configuration of
configuration setting of cores per virtual sockets on the virtual machine.

For accurate measurements, you must configure the data network interface card(s) in
mode on the host server.

Please follow the steps from chapter 3.2 when installing the software in the virtualized environment.

We recommended

disabling

any ‘Easy install’ or similarly worded option, and not selecting the
operating system type when initially creating the new virtual machine instance in your virtualization
environment. These options may override the installation instructions included in the provided
installation image, causing an incomplete installation.

18 VB330-SW 10G Software Probe User’s Manual version 5.5

• Make sure that the IP address of the gateway and the network interface are not the same.

•

Verify that the appropriate Ethernet link indicators of the PC and the 10G Software Probe are
lit.

• Verify that web browser proxy settings are not interfering.

• Verify that local firewall settings on the PC are not interfering.

• Try rebooting the server and make sure all services start as expected.

• Clear the browser’s cache.

• Verify that the web server is running, by entering the command

systemctl status httpd

on the server’s command line. If it is not running properly, or you are seeing

DNS lookup

failure errors, try issuing the command

echo "ServerName localhost" >> /etc/httpd/conf/httpd.conf

and then restart the server by issuing the command

systemctl restart httpd

•

If you can reach Software Activation but the 10G Software Probe GUI is not working, enter
the command

probehello

on the server’s command line to verify that the VB330-SW services

are running. If services are not running, try re-installing the VB330-SW.

4.4 Adjusting Alarm Thresholds

When the probe inputs and streams have been defined using default thresholds, the result will usually

be a number of more or less permanent alarms, some which may not be relevant under the current
circumstances. In order for the user to get rid of unwanted alarms, the probe provides alarm filtering
functionality in the form of alarm thresholds and alarm on/off selection.

Multicasts

By default Ethernet thresholds are set to raise alarms when service affecting errors occur, that are
caused by the network. There may however be reasons for these thresholds to be altered, for instance
to reflect receiver robustness in the case of IAT, or to reflect a TS into IP mapping different from the
default (7TS/UDP). Creating a new threshold template is done either by copying an existing one and
altering the copy, or by creating a new threshold template from scratch. The Ethernet thresholds are
defined in the
in the Multicasts — Streams view.

In addition to the miscellaneous thresholds, that affect only the streams with which they are
associated, the
overall basis. You can also define the alarm severity levels for different alarms in this view.

on the ETSI TR 101 290 guidelines and are fairly strict generating more alarms. The ETR 290
thresholds should be changed if there are tables that are not relevant for a system, or if the user
requires alarm functionality that exceeds the ETR 290 guidelines. The ETR engines has a lot of
powerful functionality not enabled by default, for instance the ability to raise alarms if the number
of services present in a signal is lower than a preset limit.

The default PID and service thresholds do not affect alarming at all, they are completely transparent.
The thresholds may be altered for instance in order to mask an alarm generated by an unreferenced

PID or to ensure an alarm is raised if a service or PID bitrate is outside preset limits.

Creating a new threshold template is done either by copying an existing one and altering the copy,
or by creating a new threshold template from scratch. The thresholds are defined in these views:
ETR 290 — ETR thresh., ETR 290 — PID thresh., ETR 290 — Service thresh.

The thresholds are associated with streams in the Multicasts — Streams — Edit view.

INTERFACE

The VB330-SW web interface is reached by pointing a web browser to the IP address of the 10G

Software Probe as shown in the screenshot above. The following web browsers are recommended:

• Google Chrome

• Mozilla Firefox

• Microsoft Edge

• Microsoft Internet Explorer 11 or higher

• Apple Safari

VB330-SW 10G Software Probe User’s Manual version 5.5 25

Note that different web browsers behave differently with respect to memory leaking, and if the

VB330-SW GUI should be available at all times the browser should be selected carefully. A browser

memory leak manifests itself as the browser responding more and more slowly, and this is corrected
by closing down the application and restarting.

The interface is easy and intuitive to use. Navigate by clicking on the tabs just below the 10G

Software Probe logo. Some of the pages have their own tabs for accessing nested pages. The bottom
frame of the interface is always the Alarms & events list, usually referred to as the
alarm list can be displayed or hidden by clicking the

head.

The web interface has been designed to be resizable in both vertical and horizontal directions with a

minimum screen resolution of 1280×800 pixels.

Tool-tips are available for most buttons and labels. To access tool-tip information simply navigate

the mouse pointer towards a button or a label and leave it hovering for a second or two.

In this manual the term stream is generally used instead of the terms multicast and/or unicast. A
stream may thus contain a single service or multiple services.
