How The Ovs System Communicates; Circuits; Sessions - Oracle Video server Manual

In a production environment, to ensure real-time delivery with no glitches, the
video server computer must be dedicated to running the OVS:

How the OVS System Communicates

This section presents these concepts related to communication in the OVS:
and discusses these processes:

Circuits

A circuit is a path of communication between the client and the OVS. A circuit can
be one of these types:

Sessions

A client connecting to the OVS establishes a session. A session consists of:
If you use logical content or scheduling, the Oracle Server for the database
must run on a separate database server computer.
If you develop server-side applications to run with your OVS, such as an
application responsible for authenticating and billing clients, they must run on
separate application server computers.

How Client Devices Connect to the OVS
How the OVS Delivers Video
upstream—carrying control messages (such as requests for video) from the
client to the OVS
downstream—carrying control messages (such as acknowledgments of
requests) and video from the OVS to the client
bidirectional—carrying control messages in both directions between the client
and the OVS
an identifier for the client
one or more circuits through which control messages and video are transported
between the client and the OVS
resources, or state information for the client and its connection to the OVS
