Putting It Together: The Video Round Trip
1-18 Introducing Oracle Video Server
Scenario 2: Enterprise Environment
In the enterprise environment, the processes of requesting titles and delivering
digital video are much the same as in the broadband environment (for details, see
Scenario 1: Broadband Environment on page 1–16), except that:
■
An enterprise environment does not typically schedule video broadcast.
Instead, it will usually make digital videos available as requested from client
machines.
■
The network communication layer, rather than consisting of a dedicated high-
speed broadband network, will instead consist of a corporate-wide LAN (Local
Area Network) or WAN (Wide Area Network). This layer might use such
communication protocols as Switched Ethernet, CDDI, or FDDI (Copper or
Fiber Data Distributed Interface).
A Switched Ethernet topology provides optimal throughput and reliability in
this environment.
Figure 1–6 shows a typical configuration for the Switched
Ethernet network used for video delivery in an enterprise environment. See
Enterprise on page 1–13 for more information on using Switched Ethernet in an
OVS system.
