11. NETWORK SPECIFICATIONS
The Optimax PA system supports audio and control data communication through Ethernet and IP
networks. Since it works on levels 3 and 4 of the OSI scale, the Optimax protocol supports
communication through routers (IP protocol) by means of the configurations of the gateways and
subnetwork masks. Thanks to these features, Optimax can work on both LANs and WANs.
Most of the communications in the Optimax systems use multicast. Multicast is an effective means of
providing transit services from one sender to many receivers. It is absolutely essential to exhaustively
and rigorously check the network configuration in order to ensure that the system operates correctly.
The multicast networks include a wide range of protocols, from filter protocols (IGMP, MLD) to routing
protocols (MOSPF, DVMRP, PIM-DM and PIM-SM/SSM).
Optimax incorporates an application-level control (ACK) (level 7 of the OSI scale) of the management
data sent.
