Short Product Description 15
3 Short Product Description
The Virtuoso is part of the Nevion cProcessor product family for processing and handling of MPEG
transport streams. The cProcessor family represents a line of compact and powerful, yet costeffective, products designed for advanced modification of MPEG Transport Streams.
Virtuoso includes Nevion’s trademark advanced protection mechanisms that enables real-time
transport of professional media over IP networks, as well as built-in monitoring that helps anticipate and correct any issues with the network or transport should they arise. Virtuoso can be
configured via an easy-to-use web interface and interact with overlaying service and network management systems. Service scheduling and provisioning is performed via Nevion’s Media Service
Management and Orchestration solution: Video IPath.
The Virtuoso M4 consists of a 1RU (Rack Unit) server chassis with an integrated processor board
for management and control, TS monitoring and processing, and IP/Ethernet network trunking
up to 10 Gb/s. In addition, it holds up to four field installable modules, each offering a number of advanced input/output, processing and networking functions at present and in the future
covering:

5.3 Seamless IP Protection Switching
Seamless IP Protection Switching (SIPS) provides redundancy by protecting the media stream
against errors in the IP network, but in a different manner compared to Forward Error Correction
(FEC). FEC is designed to protect the stream against single or short burst packet losses, whereas
SIPS provides protectionagainst loss of complete data input, for example, due to link or equipment
failure.
The main idea of SIPS is to transmit two identical copies of the media stream over separate network
paths. At the receiver side, the data from the two incoming streams are combined at packet level
to form an error free output data stream.
The combination of diverse path routing and perfect switching provides for the highest possible
Quality of Service, effectively minimizing the effects of random packet losses, burst packet losses,
losses due to fast reroutes, and link failures.
Figure 5.3 SIPS functional overview
Functional description
SIPS operates on the RTP packet level. The receive module buffers both incoming streams, mediating and selecting the most appropriate packets in what is termed active-active merging for use in
de-encapsulation. In this way, if one stream is impaired, good packets are delivered via the other
stream and a good output stream can always be reconstructed.
Virtuoso User’s Manual Rev. 2.8.30 (5370) ID: medianode
Functional Description 27
There will be packet loss at the combined stream only when the packet is received on neither of
the two IP sources. The data stream resulting from combining the two incoming data streams will
then be processed as one RTP packet stream.
Setup
At the transmitter side, the Virtuoso allows sending identical copies of the data flow to a user defined list of destinations. When several destinations have been configured for transmission, media
streams are sent to different IP addresses but the streams are identical down to the RTP layer and
are tagged with the same, randomly generated Synchronization Source ID (SSRC). For each destination, the physical or logical VLAN network interface, and IP unicast or multicast destination
addresses are configured. This enables the two data streams to be routed to their respective network paths directly at the Virtuoso or at the first subsequent network node. See Section 8.10.2.3
for more information on configuring redundant transmission/IP destinations.
At the receiver side SIPS must be enabled and the IP source parameters for IP flow A and B must
be configured to receive the media streams from the two diverse network paths. For any fully
seamless protection system to function, the dual media feeds presented at the receiver needs to
be essentially coherent i.e. the exact same media feed down to the RTP transport layer. When the
data streams have an identical SSRC value and data format, they are assumed to be identical and
are used for Seamless IP Protection Switching. See Section 8.6.2.3.2 for more info on configuration
of SIPS on the receiver.
Delay compensation
As the A and B flows will typically be routed across network links with different delays, it is
necessary for the SIPS module to wait for a period after the first signal is received before it starts
outputting data, to ensure that the second signal that is received does not need to be written to
the buffer after it is read out.
The SIPS Pre-buffer configuration parameter allows this period to be configured to allow the
system to be able to compensate for the maximum expected differential latency between the A
and B flows, while minimizing the additional delay added to the system.
Launch Delay Offset
If dual redundant network paths for some reason is not available, the Nevion patented technology
Launch Delay Offset (LDO) may be employed on the transmitter side.
This feature makes it possible to introduce a delay to one of the transmitted media streams, and
thereby introducing a temporal redundancy in the transmission. In this situation burst losses
approaching the time delay configured for LDO can be handled by the receiving SIPS engine,
even when only one network path is available.
Note that this setup will give protection against long burst losses, but not against complete network failure. If there is a need to protect against link failures, LDO should be used together with
redundant network paths (routing flow A and B through different network paths).
For information on how to configure LDO, see
Section 8.10.2.3.1.
Licensing
The SIPS feature requires a TSPROT licence at the receiving node. No licence is required to configure multiple IP destinations for an output channel on the transmit side.
The LDO feature requires the TSPROT licence at the transmitting node.
ID: medianode Virtuoso User’s Manual Rev. 2.8.30 (5370)
28 Functional Description
Compatibility
The SIPS feature is fully compatible with and extends the functionality of the SMPTE 2022-7
“Seamless Protection Switching of SMPTE ST 2022 IP Datagrams” standard.
5.4 Management subsystem
The management subsystem is a set of modules that handles all the interfaces to monitor and
control the operation of the Virtuoso.
The management subsystem communicates with the users, both humans and machines, via the
following interfaces:
• Front panel and back panel LEDs for status
• Graphical user interface via Flash application in WEB browser
• SNMP traps on alarms
• SNMPv2c Agent
• TXP (XML Protocol) to retrieve and set configuration and status
• Alarm relays on alarms
• Terminal interface either over Telnet or USB interface for debugging
• FTP server for direct file system access
The management subsystem communicates with other internal modules to make the unit perform
the wanted operations.
5.4.1 Graphical user interface
Operators monitor and control the Virtuoso mainly via the Adobe Flash GUI application served
from the device’s WEB server. The GUI application is accessed via a WEB browser that communicates with the configuration framework through an HTTP/XML based protocol.
The device exposes extensive status information to the web GUI providing detailed reports and
real-time monitoring displays to the device administrator.
All the device configuration parameters available on the Virtuoso can be controlled from the web
GUI.
5.4.2 Configuration database
The management subsystem processes configuration changes as transactions. All configuration
changes made to the device are validated against the current running configuration before committing them to the device. This limits the risks of the administrator implementing changes that
may cause down-time on the unit due to incompatible configuration settings.
Virtuoso User’s Manual Rev. 2.8.30 (5370) ID: medianode
Functional Description 29
Configurations can be imported and exported via the GUI. It is possible to clone the entire configuration of one device to another by exporting the configuration of one device and importing it to
another.
Configurations exported via the web GUI are formatted as human readable/modifiable XML files.
These files can be viewed or altered using any standard text or XML editor such as Windows
Notepad.
To simplify cloning of devices, certain exported parameters within the XML file are tagged as
device specific and therefore will be ignored when imported to either the same device or another.
These parameters are as follows:
• Device Name and Inventory ID
• IP network parameters
• ASI Port mappings
5.4.3 Alarm manager
The Virtuoso contains an integrated alarm manager responsible for consistently displaying the
alarm status of each individual interface.
“Port Alarms” are alarms bound to a specific input or output port via a port indexing system.
The alarm severity for port related alarms can be configured per port level. “Device Alarms”
are global to the device and are not bound to any specific port. They do not follow the indexing
scheme. These are classified as “System Alarms”.
Alarms are graphically represented in a tree structure optimized for simplified individual viewing
and configuration. The “Device Alarm” tree is available from the “Device Info” page. The alarm
tree for each port is available on the “Alarms” page for each port.
The alarm manager presents the alarm of highest severity upon the external interfaces of the device. The severity level of each individual alarm can be defined by the administrator. Alarm
configuration is covered in greater detail in the “Alarm configuration” section.
SNMP traps are dispatched to registered receivers whenever there is an alarm status change.
The alarm manager keeps a log in non-volatile memory of the latest 100000 alarms that have occurred.
5.5 Time synchronisation
The Virtuoso contains an internal real-time clock that is used for all internal timestamps. The
internal clock is battery backed up in order to continue operating while the unit has no power.
The internal time can be synchronised as follows:
• Manual setting.
• From NTP server using SNTP protocol.
