Grass Valley iControl V.6.02 - Manual (Page 44)

Getting Started with iControl
Example 2 — Two Application Servers, Same Subnet

4. When iC Navigator (or any client application) is downloaded from Alpha by this PC, the
application will perform a multicast discovery within Subnet A, find the Alpha Lookup
Service, and then be able to see all devices and services registered on Alpha.
5. If this PC has access to Subnet A (e.g. via VPN), it can access Alpha’s iControl—Startup page
from a Web browser, and download iC Navigator (or any client applet). The application
knows about the Lookup Service on Alpha, and so the client PC will be able to see all devices
and services registered on Alpha.
Example 2 — Two Application Servers, Same Subnet
As an iControl configuration grows, additional Application Servers can be added to handle the
increased workload. Any TCP/IP devices associated with either Application Server should be
on the same subnet.
IMPORTANT: System behavior
If the Service and alarm discovery table of Application Servers is empty,
client applications on the local Application Server can see services and
alarms coming from the local GSM and all active GSMs on Application
Servers within the subnet.
