Network Connections
Figure 2-13 shows the different logical networks of a VVI. The ingest network receives content from the
content source by way of an FTP staging server or FTP catcher where it is ingested by the Vaults. The
management network consists of communication between the CDSM and BMS, as well as
communication with the Vaults, Streamers, Caching Nodes, QAM devices, and STBs.

Ingest Interface
The ingest interface takes in FTP traffic from the content provider at a maximum rate of one gigabit per
second. After the Vault server receives URL information about the content from the BMS by using the
management interface, the ingest interface either (1) receives FTP traffic by acting as an FTP client, or
(2) receives live data upon receiving a request to act as the FTP server.
When using Layer 2 packet forwarding, to segregate all ingest traffic through the switching fabric, we
recommend the use of a port-based VLAN.
