18 Appendix A - Network design for AXUM

The platform AXUM design is according to the OSI-Model and makes use of protocols on different

levels. It is important to understand the philosophy on the different levels in networking and the way

the AXUM implemented this.

With this knowledge, you can make an advanced network setup within your studio(s) give you

possibilities for:

- Remote configuration

- Remote service

- Connecting multiple AXUM racks to internet.

- Secure working within office-networks.

18.1 Network levels

Most of the people are aware of IP addresses. IP stands for ‘Internet Protocol’ and is in the OSI-Model

called a ‘level 3’ protocol. In smaller office-networks, you normally only have to care about this ‘level 3’

(so IP).

The LAN connections (Local Area Network) normally use the Ethernet technology. Where the Ethernet

is called a ‘level 2’ protocol.

For your understanding ‘level 1’ is the physical cable like CAT5e (often called RJ45-cable or Ethernet-

cable).

An example how these ‘levels’ are used in an office network is your connection to the Internet:

- Your LAN connections are Ethernet

- Your WAN connection is DSL or GPRS/HDSPA

The fact is that the ‘level 3’ IP can be send on LAN and WAN, but the ‘level 2’ Ethernet is only

available in the local area.

18.2 AXUM Network implementation

The AXUM system communication, where you have to think of fader, knob data etc. is based on the

protocol MambaNet. MambaNet may run over other protocols and this can be L2 and L3 protocols.

Two examples of a valid AXUM solution:

18.2.1 MambaNet example 1

- MambaNet over layer 2 (Ethernet)

Is used for the Axum internal communication, where you have to think of fader, knob data etc.

etc.

- Configuration over layer 3 (IP)

Is used for the Axum configuration and service access.

This makes sense because then the AXUM internal communication is independent of any IP address

assignment and will always work independent on the IP-configuration. Second, the configuration is

based on IP so with a good network design you can access configuration and service functionality

over Internet.

Because layer 2 is a package switched solution this gives the restriction you can only use one AXUM

rack in the Ethernet network. The next example can be used in a multi-rack network setup.
