Router Configuration
Overview
Encore Router Control Application
The Encore Router Control application directs the activities of the router
matrix or matrices it has been configured to control. The Router Control
application runs on an Encore System Controller, and can control up to 32
routing matrices via Ethernet. Serial control ports can also be used, but
exhibit greater latency and lesser throughput.
The Router Control application maintains a database containing a list of
Sources (and the Levels that each Source provides), and a list of Destina-
tions (and the Levels that each Destination accepts) for the routing matrices
it controls. Routes can then be made via the Router Control application’s
own interface, or by other applications instructing the Router Control
application to make a Take (including automation systems). The Router
Control application communicates with the relevant router matrices and
instructs them to switch the appropriate cross-points. Each Router Control
application also maintains a status map (which Sources are connected to
which Destinations), creating a common view of the statuses of the routing
matrices connected to it.
A large facility may have several separate routing matrices, each used for
different purposes, and each can have its own Router Control application
running on an Encore System Controller. If multiple Encore System Con-
trollers exist in a large Encore system, each will be placed in its own Area
and run its own Router Controller. These Router Controllers are isolated,
and don’t know about others on the network. The databases for the router
matrices are combined by the Encore Control System into one large data-
base, however.
The only exception to there being only one Router Controller in each Area
is when mirrored redundancy is present. In a mirrored routing scenario
two Router Controllers located in the same Area perform the same task. All
actions/requests are sent to each Router Controller, but only one responds.
