Figure 14 shows the basic eNMS architecture frame. eNMS consists of traditional network management
modules, orchestration type of modules, and the interfacing modules. These modules are to be run on the
virtual machines in order to make the architecture scalable.

eNMSs can be deployed many places in the network as it needed and their cooperation is possible by the
“eNMS SBI” in Figure 14.

Figure 15 – eNMS recursive deployment

Figure 15 shows an example of eNMS deployment which is recursive. The eNMS SBI of one eNMS instance
will be interfacing to the NBI dispatcher of the other instance taking care of different domain.
