Chapter 1 Product Overview
Content Delivery System Architecture
In both the CDS and VVI, all Vaults and Streamers are identified by an array ID, a group ID, and a server
ID. The array ID identifies servers that are part of the same system. The group ID identifies servers that
are part of the same group (Vault Group or Stream Group), and the server ID is a unique number that
identifies the server. Table 1-3 lists the CDSM GUI ID names and maps them to the CServer names in
the setupfile and .arroyorc files.
In a VVI with CCP Streamers, similar to a CDS, all Vaults, Streamers, and Caching Nodes are identified
by an array ID, a group ID, and a server ID. The group ID and server ID in a VVI with CCP Streamers
must be unique among other groups and servers in the same system.
In a VVI with HTTP Streamers, the Vaults, Streamers, and Caching Nodes still use an array ID, a group
ID, and a server ID for identification, but there is additional functionality that allows the Vaults and
Caching Nodes to communicate using CCP, while the Caching Nodes communicate with the Streamers
using HTTP. It is not required that the group ID and server ID be unique, but it is recommended.
The CDSM and VVIM (as well as the Stream Manager) have three configuration and monitoring levels:
system, array, and server. System-wide configuration affects all servers managed by that manager. The
array-level configuration affects all the servers of the specified array or group, and the server-level
configuration applies changes to a specific server.
The CDSM and VVIM offer a drill-down approach to show the status of any stream or ingest point, or
the physical status of any piece of hardware.
The CDSM reporting helps operators manage all aspects of the TV CDS. Information on stream traffic,
content statistics, and server data are gathered from all servers in the network and correlated
automatically, showing at a glance the status of the network and reporting on statistics such as content
popularity, stream usage, and bandwidth usage for each service group.
The VVIM monitoring and reporting helps operators manage all aspects of the TV VVI in either a
centralized management capacity or a split-domain management capacity. In a split-domain capacity, the
VVIM monitors the ingests and the Stream Manager monitors the streams of the Streamers in its domain.
