3.3.6 N+1 REDUNDANCY

The N+1 Redundancy menu is used for setting up N+1 redundancy groups, and assigning Chameleons as ”operational” or ”reserve” for the groups. Operational Chameleons are ”on-line”, while the reserve Chameleons are kept ”off-line” until they needs to be used due to an operational Chameleon failure. For N+1 redundancy, each redundancy group must contain at least one operational Chameleon and one reserve Chameleon.

Note that a redundancy group can

contain more than one operational

Chameleon, and the reserve

Chameleon in a redundancy group will

take over the function of any failing

operational Chameleon in the group.


www.wisi.de

Redundancy switch criteria and switch over processThe criteria for switching to a reserve Chameleon in a group is that the operational Chameleons in the group does has a failure and does not start, or starts in rescue mode.

For each defined redundancy group, the configuration of the operational Chameleons are stored, and when a redundancy switching is triggered, the configuration of the failing Chameleon is uploaded to the reserve Chameleon. To ensure that the failing Chameleon is not transmitting signals that can disturb, the configuration of the failing Chameleon is removed.

The N+1 Redundancy menuThe N+1 Redundancy menu has 4 columns; Slot, N+1 Group, Reserve and Status. A slot without inserted Chameleon will be indicated by “Module not present”. The N+1 Group shows which redundancy group each Chameleon belongs to (no digit in this column means that this Chameleon/slot is not member of any group). The Reserve column has a tick for Chameleons that are reserve modules.

The Status column shows if a Chameleon is inserted, and if it is working or not.

Assigning Chameleons to redundancy groupsTo set up a redundancy group, at least 2 Chameleons should be used, one as operational and one as reserve.

Set a Chameleon as operational for a redundancy group1. Assign the Chameleon you want to use as operational to a group by clicking on the tailing

2. Click on ”Set as operational for N+1 Group”

HEADEND SYSTEM MANAGEMENT & HEADEND GROUPS 25

www.wisi.de

6. HEADEND SYSTEM MANAGEMENT & HEADEND GROUPS

Headend system management is the menu under SETTINGS where you manage the Headend Groups. For brevity, the notations HE System Management and HE Groups will be used.

6.1 THE HE GROUP CONCEPT

HE Groups are used to enable communication between modules that are group members. Any GN50 or Chameleon in the same local network can be included in the same group, and there is no specific setting in the modules to allow inclusion or exclusion to/from a HE group. As a consequence, setting up a HE group can be done from any module. For more information about requirements for a “local network”, see §6.1.5.

There are 2 functionalities that use the HE Group concept:

■ The sharing of PSI/SI to create DVB Network-wide PSI/SI, §6.1.2

■ The System UI, §6.1.3

6.1.1 ADDING / REMOVING MODULES TO/FROM HE GROUPS

1. Click EDIT to list all modules. The modules will be listed by their serial number

2. To add a module to the group, click the green tailing the serial number in the list of Selectable units. The serial number will be added to the list under Group units

3. Click SAVE

■ To remove a module from the group, click the red tailing the serial number in the list of Group units, and click SAVE

The HE Group settings done in one

Chameleon or GN50 will automatically

be propagated to update the HE Group

settings for all modules in the group.


www.wisi.de

6.1.2 HE GROUPS FOR PSI/SI SHARING

For creation of a DVB network-wide correct PSI/SI structure, information about PSI/SI has to be shared between the Chameleon modules in the same DVB network. The basis for such a sharing is that the Chameleons are interconnected via a switch (in the GN50 via the embedded GT11 switch), and that a communication between the Chameleons is set up by adding all Chameleons to the same HE Group.

The PSI/SI sharing additionally requires that all Chameleons have the SW option GNSYMUX (system remux). For more information, please refer to the Chameleon Manual and Installation Guide.

6.1.3 HE GROUPS FOR SYSTEM UI

The System UI is used for access to:

■ the individual UI for each module in a HE Group

■ he “system overview” UI, where information from all modules in HE Group is presented in a single web UI

The “system overview” will henceforth be called the System mode.

The System mode enables you to e.g. get an overview of the status of all modules in a single view, or overviews of all input and output services in a single view. In some menus in System mode, you can edit information or manage e.g. services and PIDs. Extensive information about the System mode is given in §7.

The exchange of information between the modules for System mode is based on membership in the same HE Group.

The System mode is entered by selecting -- System mode -- in the system modules list, see the picture to the right. For further information about the system UI and System mode, see §7

6.1.4 CHAMELEON FIRMWARE REQUIREMENTS

Important note: Chameleons must run FW1.8.2

When running SW version 1.1.1 for GN50, all Chameleons installed in the GN50 must have FW1.8.2 or later. Previous FW versions for Chameleons are not supported with SW version 1.1 in GN50.

Moreover, Chameleons that are not installed in a GN50, but are connected to a GN50 for System UI, must also run FW1.8.2 or later.


www.wisi.de

6.1.5 “LOCAL NETWORk” REQUIREMENTS AND SYSTEM UI PERFORMANCE

Local networks and HE GroupsAny Chameleon, in GN50 or not, will be aware of all other Chameleons on the same “local network”. Here, a local network is defined as a layer 2 LAN, i.e. a LAN where no router or gateway is needed for the connection between the modules in the network.

SW options and base units requirements for the System UIAny Chameleon in a layer 2 LAN can be added to a HE Group, disregarding the base unit used. If the HE Group is used for system UI, the following is required:

■ at least one GN50 has to be included in the HE Group to enable the system UI

■ Chameleons that are not installed in a GN50 must have the SW option GNSYSMG (system management)

Chameleons installed in a GN50 automatically has the ability to share information for the system UI.

When connecting several GN50 base units, or when connecting a GN50 to Chameleons in other base units (GN40/GN01/GN20), use an external switch and connect the management ports of the GN50 base units and the Chameleons.

HE group size and system UI performanceThere is no restrictions to the number of Chameleons you can add to a HE Group. However, if large number of modules, or large number of services are to be handled, the rendering of the web pages showing e.g. all services in the HE Group will become more time consuming. This will mainly be noticed in the Services view of Service Management. If your system contains large number of services, please allow some time for the rendering of all services in the Services view of Service Management.

In this context, a large HE Group for System UI is a group with more than 20 Chameleons.

If large systems are used for system UI, the performance of the system UI will be enhanced by using the Google Chrome web browser on your computer.

SYSTEM UI – SYSTEM MODE 28

www.wisi.de

7. SYSTEM UI – SYSTEM MODE

7.1 GENERAL ABOUT SYSTEM MODE AND SYSTEM UI

The System mode in the system UIThe System mode is a single UI for management and configuration of all modules in the same HE group. To access the System mode, select the “- -System mode - -” in the drop-down list of the system modules list. Information about settings for all modules in the group is displayed in a unified view that has the same menu entries as the individual UIs:

STATUS, INPUTS, OUTPUTS, SERVICE MANAGEMENT and SETTINGS.

INPUTS and OUTPUTS menus in the System mode are not active in the SW version 1.1.1.

The system modules list and HE groupsIn the top bar of the UI of GN50 you will find a drop-down list called the system modules list. This list will contain all modules that are included in the HE Group, see §6. The UI of any individual module (Chameleon or GN50) can be accessed by selecting the module (by name, or by serial number) in the list. For information about managing the GN50 via its UI, please refer to §3 in this User Manual. For information about managing Chameleons in their individual UI, please refer to the Chameleon Manual and Installation Guide.

To access the System UI, you connect to a GN50 by entering the IP address of the GN50 in the address field of your browser (see §2.3). The module you have accessed directly via its IP address is marked with a *, in the picture below the “* GN50 main (GT11)”.


www.wisi.de

7.2 STATUS IN SYSTEM MODE

In the STATUS menu of the System mode, all modules in the HE Group are listed. General status information, Name, Type, SW, Uptime, Temperature and State is given for each module. Modules that do not have a name will be listed with the serial number.

Expanding an entry line for a module in the STATUS list by clicking the leading will give you all information from this modules STATUS menu in a condensed format.

Please note that the entries in these condensed status views are read-only. However, by clicking the edit arrow tailing the module line, you can navigate directly to the different parts of the individual UI of this specific module.

Module menu entries in the Status view of the system modeThe different parts of the UI of an individual module, Status, Inputs, Outputs, Service Management and Settings, can be accessed directly via clicking the edit arrow tailing the module listing in the Status view of the system UI and selecting the menu of interest.


www.wisi.de

State and warning messagesIn the State column, a module that has an erroneous setting, or a configuration that is giving a warning message in its individual UI, is marked with a red exclamation mark The red warning exclamation icon has a hover functionality, and placing the mouse pointer over the icon gives you detailed information about the error in the individual module in a Required Action Summary pop-up.

The warnings in the Required Actions Summary pop-up are links directly to the part of the individual module UI where the warning originates. Click on the warning message or the tailing arrow to go directly to module where to rectify the problem.

Clicking the edit arrow tailing the module line, you will also be given an indication from which part of the individual modules UI the inconsistencies stem.

To return to the system UI, you can use

the “back” function in your browser.


www.wisi.de

7.3 INPUTS & OUTPUTS IN SYSTEM MODE

In the current version of the System mode, the INPUTS and OUTPUTS views only contains references to the INPUTS and OUTPUTS views of the individual Chameleon modules. You can use the system modules list in the top bar to go directly to the Chameleon where you would like to modify any settings for the inputs or the outputs.

Please also note that you can use the grey arrows to the far right of a module in the STATUS view of the System mode to go directly to any part of the UI of this module.

The System mode is mainly designed to handle transport streams, services and PIDs in unified views. The settings of parameters for the physical inputs and outputs are normally linked to also connecting antenna inputs and RF outputs. As such, it is reasonable to manage these settings in the individual UI for each Chameleon.

7.4 SERVICE MANAGEMENT IN SYSTEM MODE

Service management functionality and pre-requisitesThe SERVICE MANAGEMENT tab is the main view for handling remultiplexing, service selection, decryption, encryption and PID management. The inputs and outputs of the Chameleon modules must be configured before using Service Management, please refer to the Chameleon Manual and Installation Guide.


www.wisi.de

Service Management - left part for Inputs, right part for OutputsThe Service management has 2 main parts. The left part for information about inputs (Modules, Inputs, Services) and the right part for information about the outputs (Modules, Outputs, Services). You can select to show information about Modules, Inputs/Outputs or Services by clicking the tabs at the top of the 2 main views.

■ In the Modules view, the listings are based on the physical Chameleons, see §7.4.1

■ In the Inputs view, the listing is based on the configured inputs in, see §7.4.2

■ In the Outputs view, the listing is based on the configured outputs, see §7.4.2

■ The Services views list all incoming/outgoing services, see §7.4.3

Please note that the selection of views (Modules, Inputs/Outputs or Services) is independent for the input side and the output side. You can select e.g. to have the Modules view for the inputs, and the Services view for the outputs.

Information about modules, inputs/outputs, services and PIDs can be accessed in any view, and the view you select to work with will depend on what you want to check or configure. The Service Management is used for selecting services from inputs to outputs, and managing PIDs. Configuration of modules and physical inputs/outputs is done in the user interfaces of the individual modules.

If no menu arrow is present, the information is read-only.

INPUT level pop-up menuThe pop-up menu at Input level allows you to add all services of an input to an output, or to connect an input transparently to an output. The Character encoding menu allows you select the encoding standard for the service names and for the provider names. For more information, please refer to the Chameleon User Manual.

Add all services

Click on Add all Services, and select the output to add the services to.

This will result in the same as adding all services one by one on the SERVICE level, and the automatic remultiplexing including creating correct PSI/SI will be done.

Connect transparently to

When you select Connect transparently to, all services of an Input will be added to the selected output, and no change is done in the PSI/SI information.

SERVICE level pop-up menuThe pop-up menu at SERVICE level allows you to add services one by one to an output.

The Descramble command sets all PIDs to be descrambled. This command is only available for CI inputs. For more information about the settings for the Common Interface, please refer to the Chameleon Manual and Installation Guide.

PID level pop-up menuThe pop-up menu at PID level allows you to descramble individual PIDs of a service. This menu is only available for CI inputs.

The Descramble command on PID level is activated only if the service is descrambled on SERVICE level.

When selecting to descramble a PID,

all other PIDs will become not selected

for descrambling. Hence, if you need

to descramble on PID level, make sure

that you select descramble for all PIDS

GN50 STREAMING INTERFACES 45

www.wisi.de

8. GN50 STREAMING INTERFACES

8.1 PORTS AND PORT CAPACITY

Port assignment and internal streamingThe embedded switch, GT11, has 5 RJ45 GigE ports for management and streaming, accessible from the rear of the GN50:

■ Management port (Mgm) for the connection to the UI of the GN50 and to the UI of the Chameleons

■ The Streaming ports 1, 2, 3, 4 connected to Chameleons by selecting VLAN Port 1, Port 2, Port 3 or Port 4.

Bitrate limitations ■ Bit rate per streaming port < 1 Gbit/s

■ Bit rate per Chameleon backplane slot < 1 Gbit/s

8.2 VLAN SETTINGS FOR THE CHAMELEONS

VLAN assignment for Chameleons with external IP in/outTo enable the Chameleons to stream in or out of the GN50, the VLAN must be set. All streaming ports (streaming port 1 to streaming port 4) can be used for external streaming.

The VLAN is configured in the UI of the Chameleons, in Networking under SETTINGS. For more information, please refer to the Chameleon Manual and Installation Guide.

VLAN assignment for Chameleons with internal IP in/out: VLAN Internal streamingChameleons that stream between modules in a GN50 should use VLAN Internal streaming.

Slot indications vs. physical slotsThe physical slots in GN50 are numbered from 1 to 10, starting from left for a rear view of the GN50. S

8.3 CONNECTING THE GN50 TO YOUR IP NETWORk

Tagged/untagged IP traffic and VLANTraffic to and from the GN50 is expected to be untagged, both for the Management port and for the Streaming ports 1-4. VLAN tagged traffic is only used internally for traffic between the Chameleons via the GT11 embedded switch.

IP streaming traffic – Multicast and UnicastThe configuration of the GT11 allows Multicast and Unicast streaming both internally and externally.

Design rules for connecting GN50 to an IP networkDo NOT connect the Management port to the same LAN/VLAN as any of the other ports (port 1, port 2, port 3, port 4).

The diagram below gives an example for a configuration following the design rules above.

8.4 IGMP SNOOPING AND INTERCONNECTING GN50S

IGMP snoopingGN50 use IGMP snooping for filtering of incoming (external) Multicast traffic, and for internal Multicast traffic. Outgoing Multicast traffic is flooded on the streaming ports.

The internal IGMP snooping does not require any IGMP querier.

Multicast traffic between GN50s, without going via an external switch, does not require any querier.

Sharing services between 2 GN50 via direct connection between the 2 GT11 switchesIf you want to “share services/payload” between Chameleons in 2 different GN50’s without exposing this IP traffic to the external IP network, you can connect an IP cable directly from a streaming port in one GN50 to a streaming port in the other GN50.

In SW1.1, any slot can be connected to any streaming port in GN50. To interconnect 2 GN50 for payload sharing, one (anyone) of the streaming ports in GN50 nr 1 can be connected directly to one (anyone) of the streaming ports in GN50 nr 2. Note that no VLAN tagging is used for external traffic, also not for traffic between 2 GN50 base units.

Example 1: Chameleons in slot 1 to slot 10 in GN50 nr 1 can share services with Chameleons in slot 1 to slot 10 in GN50 nr 2 via direct interconnection from streaming port 3 in GN50 nr 1 and streaming port 2 in GN50 nr 2.

APPENDIx

Domain Name System (DNS)The Domain Name System (DNS) is an application layer protocol. It is used to convert a computer’s host name into an IP address on the Internet. For example, if a computer needs to communicate with the web server example.net, your computer needs the IP address of the web server example.net. It is the job of the DNS to convert the host name to the IP address of the web server.

Dynamic Host Configuration Protocol (DHCP)The Dynamic Host Configuration Protocol, is a protocol related to computers and networks of computers. It is referred to as DHCP for short. It was made so that computers could connect to other computers (on a network) automatically. To be able to access the Internet (or any computer network), an IP address is needed. DHCP allows for this IP address to be obtained automatically. Other data, like a DNS Nameserver, or a time server can also be obtained that way.

Internet Group Management Protocol (IGMP)Internet Group Management Protocol or IGMP is a network protocol used to manage the membership of IP multicast groups. IGMP is used by IP nodes and adjacent multicast routers to establish membership (s) in multicast groups. It is an essential part of IP multicast specification and similar to ICMP’s function in “normal” IP connections. IGMP can be used for one-to-many networking applications such as online streaming video and gaming, and allows more efficient use of resources when supporting these types of applications.

Network Time Protocol (NTP)The Network Time Protocol (NTP) is a protocol for distributing the Coordinated Universal Time (UTC) by synchronizing the clocks of computer systems over IP networks. No information about time zones or daylight saving time is transmitted; this information is outside its scope and must be obtained separately.

NTP is one of the oldest Internet Protocols still in use (since before 1985) and uses UDP port 123.

IGMPv2 improves over IGMPv1 by adding the ability for a host to signal desire to leave a multicast group. IGMPv3 improves over IGMPv2 mainly by adding the ability to listen to multicast originating from a set of source IP addresses only.

Local area networksA local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their usually higher data-transfer rates, smaller geographic area, and lack of a need for leased telecommunication lines.

Layer 2 LAN is a local area network where no router or gateway is required to interconnect devices in the network.

www.wisi.de

Private networksIn the Internet addressing architecture, a private network is a network that uses private IP address space. These addresses are commonly used for home, office, and enterprise local area networks (LANs), when globally routable addresses are not mandatory, or are not available for the intended network applications.. If such a private network needs to connect to the Internet, it must use either a network address translator (NAT) gateway, or a proxy server.

VLAN (Virtual LAN)In computer networking, a single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN or VLAN.

This is usually achieved on switch or router devices. Simpler devices only support partitioning on a port level (if at all), so sharing VLANs across devices requires running dedicated cabling for each VLAN. More sophisticated devices can mark packets through tagging, so that a single interconnect (trunk) may be used to transport data for various VLANs.

Grouping hosts with a common set of requirements regardless of their physical location by VLAN can greatly simplify network design. A VLAN has the same attributes as a physical local area network (LAN), but it allows for end stations to be grouped together more easily even if they are not on the same network switch. VLAN membership can be configured through software instead of physically relocating devices or connections. Most enterprise-level networks today use the concept of virtual LANs. Without VLANs, a switch considers all interfaces on the switch to be in the same broadcast domain.

To physically replicate the functions of a VLAN would require a separate, parallel collection of network cables and equipment separate from the primary network. However, unlike physically separate networks, VLANs share bandwidth, so VLAN trunks may require aggregated links and/or quality of service priorization
