Note Table 2-2 lists the mandatory interfaces for each CDS server. If HTTP Streamers are used in a VVI, each
Caching Node must have one interface designated as the Locate interface. Stream Control is an optional
interface function. For more information, see the “Configuring the Interfaces” section on page 4-109.
Figure 2-11 shows the different logical networks of a CDS consisting of Vaults and Streamers. The
ingest network receives content from the content source by way of an FTP staging server or FTP catcher
and the content is ingested by the Vaults. The management network consists of communication between
the CDSM and the BMS, as well as communication with the Vaults, Streamers QAM devices, and STBs.
The cache network consists of Vaults and Streamers.
