for these network connections. The design is filed in the
WINMAN system. The required resources are reserved for the
timeslots in which the ICS will be operational. The ICS state
becomes reserved.
3. Implement the ICS. This step describes the WINMAN system
responsibilities for the implementation of the network connections.
The implementation starts when the ICS is at the point of
becoming operational (scheduling). Then the WINMAN system
allocates the required network resources and changes their usage
state from idle to active or busy. So far, the managed network has
not been involved in the implementation. Then, the WINMAN
system allocates the physical resources in the managed network
through the IP or WDM EMSs. Subsequently, the parameters of
the network resources are provisioned, and the network connection
is set up and tested. The ICS state becomes implemented.
4. Activate the ICS. This step describes the WINMAN system responsibilities
for the activation of the ICS. This step involves the interaction
of the WINMAN system with the managed network, which
leads to the operational state of the ICS. The ICS state becomes
operational.
