16 Appendix A - Network design for Oxygen 5 Digital
The platform Oxygen 5 Digital 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 Oxygen 5 Digital 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 Oxygen 5 Digital racks to internet.
-
Secure working within office-networks.
16.1 Network levels
Most of the people are aware of IP addresse s. IP stands for ‘Internet Protocol’ and is in the OSI-Model
called a ‘level 3’ protocol. In smaller office-networks, you 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.
16.2 Oxygen 5 Digital Network implementation
The Oxygen 5 Digital system network levels are used as follow:
-
Level 2 (Ethernet)
Is used for the Oxygen 5 Digital internal communication, where you have to think of fader,
knob data etc. etc.
-
Level 3 (IP)
Is used for the Oxygen 5 Digital configuration and service access.
This makes sense because then the Oxygen 5 Digital 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.
16.3 Network design
An Oxygen 5 Digital system require to have an own LAN (level 2) to work without risk of interference
with office networks and or other Oxygen 5 Digital systems. The most basic way of describing this is:
“Each Oxygen 5 Digital system requires its own Ethernet switch”.
As you can understand this means there is no connection (so communication possible) between the
separate LANs. This creates the problem you cannot access the console(s) from a single internet
connection or from your office network. To overcome this problem you have to design the network with
a separation on ‘level 2’ (Ethernet) but a connection over ‘level 3’ (IP) must be possible.
Most simple example on such separation is:
