Engineering Access Level Pages


This appendix describes the VVIM or CDSM pages available through the Engineering access level. The Engineering access level provides the following pages:

CDSM or VVIM Diagnostics

CDSM or VVIM Setup

System Configs

The Engineering access level is primarily used for initializing the CDS at the time of installation and for system diagnostics. After your system has been configured, you should not require an engineering access level user for day-to-day operations.

When you log in to the CDSM with a user account that has Engineering access level, the first page that is displayed is the CDSM Setup page. All the other CDSM pages that are available with the Master access level are still available with the Engineering access level.

In an RTSP environment, the Configure > Server Level > RTSP Setup page displays four additional fields:

Database Connect Size

UDP Packet Size

Threadpool Size

Max Sessions

These fields are only for diagnostic purposes, and their values should not be changed.


Note When you configure the CDSM for Virtual Video Infrastructure (VVI), all references to CDSM are changed to Virtual Video Infrastructure Manager (VVIM) for the Vault and Caching Node manager. For example, the CDSM Audit Logs available through the Report > System Level left-panel menu is changed to the VVIM Audit Logs when VVI is configured on the CDSM Setup page, which changes to the VVIM Setup page.


CDSM or VVIM Diagnostics

To access the CDSM or VVIM Diagnostics page, choose Maintain > Software > CDSM Diagnostics or VVIM Diagnostics. The first section of this page provides configuration information that is useful in diagnosing a problem. The following remaining sections of the CDSM or VVIM Diagnostic page are:

CIDR Calculator

Stream Trickmode Debugger

Unix Timestamp Tool

Server Diagrams

CIDR Calculator

By entering an IP address and network mask, and clicking Submit, the Classless Inter-Domain Routing (CIDR) Calculator provides the following TCP/IP network information:

Network address

Broadcast address

Number of hosts

Range of IP addresses for the hosts

Stream Trick-Mode Debugger

To view the trick-mode data for a Session ID enter the Session ID and click Submit. The CDSM or VVIM Diagnostic page refreshes and a View Data button is displayed next to the Submit button. Click View Data to see the raw trick-mode data. A new window displays the data. Right-click in that window and choose View Source in the pop-up menu. A formatted version of the raw data is displayed.

Unix Timestamp Tool

Clicking on a day in the calendar displays the Unix start time and end time. The time is represented in seconds since the start of Unix epoch time, which is 1970-01-01T00:00:00.

Server Diagrams

Choose a server from the Server Diagrams drop-down list and a graphic of the server is displayed.

CDSM or VVIM Setup

The CDSM or VVIM Setup page is used to initially configure the CDS. After you have set the CDSM or VVIM Setup fields for your system, click Submit. Configuration and start up messages are displayed in the left panel.

Deployed CServer Version

This field is always set to 2.X.

Stream Failover Support

Stream failover support is available for both the ISA and RTSP environments. If a Streamer fails, another Streamer in the same Stream Group takes over any active stream sessions without loss of state and backoffice independence.

Stream Steering Mode

Stream steering determines which Streamers serve streams to a QAM device. There are two types of stream steering:

Single site (Silo site steering)

Multi-site

Single-site steering uses only one Stream Group to serve streams to all QAM devices. Multi-site steering can use more than one Stream Group to serve streams to the QAM devices. The QAM Gateway page reflects whether single-site or multi-site steering is enabled, by the number of preference levels available. Multi-site steering offers four preference levels (high, medium, low, and none). Single-site steering offers two preference levels (high and none).


Note Multi-site steering is available only with ASI streaming in an ISA environment.


Deployment Network Config

Specify whether your CDS network topology is a Layer 2 or Layer 3 network.

Installation Type

The only options are ISA 2.X and RTSP 2.X.

Stream Destination

The possible settings for Stream Destination are Cable and IPTV.

The cable setting is the existing configuration with the QAM Gateway page and Headend Setup page, which allows you to map Stream Groups to QAM devices and service groups if applicable.

The IPTV setting provides the Stream Destination page in place of the QAM Gateway page and Headend Setup page. The Stream Destination page allows you to map the Stream Groups to specified subnets, which is useful in IPTV networks where each end-user has an IP address.

An option for ISA environments using the IPTV setting for the Stream Destination is the NAT option. The NAT Traversal feature allows streaming to client devices that are behind a NAT device.


Note The Stream Destination feature is available only for single-site steering.


Parent/Child Service Groups

Parent/Child Service Groups is an optional feature and is only for ISA environments that use ASI streaming. The Parent/Child Service Groups page allows finer granularity of the service groups.

Redirect Server

Redirect Server is an optional feature for RTSP environments. The RTSP server on the Streamer sends a redirect to the "best" Streamer to serve the content. When set to ON, the Redirect Server configuration page is displayed at the System Level, and you can specify the port number used to receive the redirect requests, as well as set the debug level.

Bulk Configuration

Bulk Configuration provides a method of configuring common configuration parameters for all the servers at one time by means of an XML file. Following are the CDSM GUI configuration pages that offer bulk configuration:

QAM Gateway

Headend Setup

Stream Destination

NTP Server

Server DNS

SNMP Agent

Route Tables

RTSP Setup

FSI Setup

SSV Groups

When SSV Groups is enabled, Stream Groups, Vault Groups, and Cache Groups are disabled.


Note The SSV Group optional feature is only applicable to RTSP environments and for a CDS that uses only ISVs.


The Thin Pipe Map page and Vault Redundancy Map page are also displayed when SSV Groups is enabled. The Vault Redundancy Map page allows mapping of ISVs for mirrored content, and the Thin Pipe Map page allows creation of low-bandwidth connections between local and remote groups.


Note The term SSV used in the CDSM GUI is the same as the ISV. The terms are interchangeable.


When SSV Groups is enabled, all pages referring to Vaults or Streamers display as SSV instead. These pages include the Stream Destination page, the QAM Gateway page, the Headend Setup page, the Control/Setup IP page, and the Vault Redundancy Map page.

Trick Mode Capture

In Release 2.2, Trick Mode Capture is an optional feature. When Trick Mode Capture is enabled, the applicable Stream Activity reports can drill down to the Stream Play History Drilldown, which displays the trick modes for a session ID. Additionally, the Graph Stream button is displayed on the Stream Monitor page. The Stream Activity reports that can drill down to the Stream Play History Drilldown are the following:

Stream Play History

Streams by Array

Streams per STM-MAC

Bandwidth per Service Group

Stream Failures

When Trick Mode Capture is disabled, the session ID in the Stream Activity reports no longer links to the Stream Play History Drilldown and the Graph Stream button is removed from the Stream Monitor page.

Vault Redundancy

When Vault Redundancy is enabled and at least two Vault Groups are configured and mapped to each other, at least one copy of each content within a group is mirrored to the configured peer group. Content is mirrored among as many as four Vault Groups (one Vault Group ingests the content and up to three Vault Groups mirror the content), which may be in different geographic regions. The Vault Redundancy adds the Vault Groups and Vault Redundancy Map configuration pages to the Array Level.


Note In Release 2.4, the maximum number of Vault Groups is 20.


RS DVR

This feature is not activated in this release.

Thin Pipe Management

Thin Pipe Management allows you to configure low-bandwidth connections between local and remote groups. A local group consists of servers in the same group (Stream Group, Cache Group, Vault Group). A remote group consists of servers in other Stream Groups, Cache Groups, and Vault Groups. Use the Thin Pipe Map page to configure this feature.

Shared Content Store

Shared Content Store is an optional feature for the ISA environment. The Shared Content Store allows one instance of a Content Store to be shared with many instances of Stream Services, each located in its own video hub office (VHO) with its own video backoffice (VBO).

Virtual Video Infrastructure

The Virtual Video Infrastructure (VVI) provides management of the Caching Nodes in a central management configuration or a split-domain management configuration.

When you enable VVI, you need to choose the Management System Role of the CDSM. The Management System Role has the following options:

VVI and Stream Manager—Central management of all Vaults, Caching Nodes, and Streamers

VVI (Vault/Cache) Manager—Management of only the Vaults and Caching Nodes

Stream Manager—Management of only the Streamers

The Cache Fill Protocol options are for selecting the type of data communication that is used between Caching Nodes and Streamers. Cache Control Protocol (CCP) is used for communication among the Vaults, Caching Nodes, and Streamers. For more information about CCP Streamers and HTTP Streamers, see the "Caching Node Workflow" section on page 6-9.


Note ISA environments only support CCP, while RTSP environments only support HTTP for VVI.


The split-domain management is made up of the VVI (Vault/Cache) Manager and the Stream Manager. For the Stream Manager to be able to communicate with the VVI Manager, you need to enter the IP address of the VVI Manager in the VVI (Vault/Cache) Manager VVIM IP field.

If CCP is used as the cache-fill protocol, you must provide a name for the Stream Manager in the Stream Domain Name field so that the VVIM can identify it from other Stream Managers. Communication between the VVI Manager and the Stream Manager is accomplished through database replication when using CCP.

If you choose HTTP, communication between the VVI Manager and the Stream Manager uses port 80. If port 80 is not open for communication, you can enter the data manually (used for Stream Group IDs), or upload an XML file (used for Cache Group Locator information), depending on the information required.


Note When you configure the CDSM for Virtual Video Infrastructure (VVI), all references to CDSM are changed to Virtual Video Infrastructure Manager (VVIM) for the Vault and Caching Node manager.


The VVIM and Stream Managers display different configuration, monitoring, reports, and maintenance pages based on the servers they manage. For example, when CCP is the cache-fill protocol, the VVIM displays the Configuration Generator page in the Maintenance > Software left-panel menu. The Configuration Generator page is used to generate the group IDs and server IDs for the Stream Managers to use in their domains.

Configuring Split-Domain Management

To configure a VVIM that uses split-domain management, set the VVI fields as follows:

VVI Options—Enabled

Management System Role—VVI (Vault/Cache) Manager

Cache Fill Protocol—HTTP or CCP (Must be configured the same as the Stream Manager.)

To configure a Stream Manager that uses split-domain management, set the VVI fields as follows:

VVI Options—Enabled

Management System Role—Stream Manager

Cache Fill Protocol—HTTP

VVI (Vault/Cache) Manager VVIM IP—IP address of the VVIM

Stream Domain Name—Domain name for the Stream Domain (If CCP is the Cache Fill Protocol)

Media Scheduler

The Media Scheduler is an optional feature and requires a software activation key to enable it. For more information about activating the Media Scheduler, see the "Initializing the CDS and Activating the Optional Features" section on page 2-3. The Media Scheduler allows live ingests from multicast IP addresses and uses the Input Channels page to map multicast IP addresses to channels. You can enable either Media Scheduler or Real-Time Capture Type, but not both.

Real-Time Capture Type

Real-Time Capture allows live ingests from multicast IP addresses and uses the CallSign Setup page to map the multicast IP addresses to call signs. You can enable either Media Scheduler or Real-Time Capture Type, but not both.

Bandwidth Manager

The Bandwidth Manager is an optional feature and is only for RTSP environments. The Bandwidth Manager keeps track of allocated streams and VOD network resources.

Ingest Manager

The Ingest Manager is an optional feature and requires a software activation key to enable it. For more information about activating the Ingest Manager, see "Initializing the CDS and Activating the Optional Features" section on page 2-3. The Ingest Manager takes care of provisioned content objects by collecting the metadata, sending messages to the appropriate subsystem to ingest the content, and sending messages to expire the content when the expiration period has passed.

RTSP Deployment Type

The RTSP Deployment type is applicable only to RTSP environments. The options are the following:

DSM-CC

RTSP

NGOD

IPTV

Quative

EventIS (on vpath and off vpath)

Cisco

The deployment configuration differs depending on the type of headend.

Content Propagation

The Content Propagation setting determines whether content information is propagated to the Streamers or not. This setting is applicable only to RTSP environments.

When the RTSP Deployment Type is set to NGOD, set the Content Propagation to Not Propagated. This setting allows content information to be stored on the Caching Nodes in VVI RTSP NGOD deployments. The Streamers check their local database for a record of the content. If the content is not found, the Caching Nodes are queried for the content record.

For all other RTSP Deployment Types, set the Content Propagation to Propagated. This allows content information to be stored on the Streamers.

Authentication Manager

The Authentication Manager is an optional feature and is only for specific RTSP environments (EventIS). The Authentication Manager communicates with the backoffice to validate a request received from a set-top box before setting up a session.

The Protocol options are for selecting the RTSP deployment type for the Authentication Manager. Cisco is used for the Cisco RTSP deployment and EventIS is used for the EventIS RTSP deployment.

Service Group Steering

Service Group Steering is an optional feature and is only for RTSP environments. When the Service Group Steering option is turned on, the Configure > System Level > Headend Setup page is available to steer Stream Groups to specific service groups.

CDSM or VVIM NAV Setup

The CDSM NAV Setup changes what displays in the CDSM GUI.

CDSM or VVIM Health Monitoring

The CDSM Health Monitoring optional feature displays the Server Level monitor page, Server Vitals page and a Vitals column in the System Health Monitor page. The Server Vitals page displays the current values, as well as thresholds, for monitored system components on the server. Server components are monitored and when a threshold is exceeded, the System Health Monitor page and Server Vitals page report the event and an SNMP trap is sent.

System Configs

The System Configs page contains critical CDS parameters that are set at the time of the initial installation of the CDS. Generally, the default settings are appropriate for all environments.


Caution If these parameters are changed after the CDS is in service, your CDS may not function properly.

Group Map 0

Specifies whether the Group Map 0 parameter is for an ISA or RTSP environment.

Servers Group Map

Specifies whether the Servers Map 0 parameter is for an ISA or RTSP environment.

License Map

This is the CDS license, and is set at the time of installation.

Control IP Map

The Control IP Map is always set to one.

Add New Server

Should you experience problems adding a new server into the CDS, and you have tried the solutions covered in the "CDSM GUI Does Not Register the Vaults and Streamers" section on page A-23, you can use the Add New Server section.
