6.1 Ethernet
Alyseum products rely on Ethernet to transport data; compared to other solutions (USB, IEEE1394
...) Ethernet offers many advantages:
● Available on all computer platforms
● No practical limit in setup size and span or in node connections
● Full
Duplex
● Very high bandwidth & low Latency
● Frees the computer of the MIDI flow handling of USB/Firewire interfaces
● Embedded devices can work without any computer in the network
● Peer to peer capability
● Full electrical isolation between machines, preventing audio hum due to ground loops
● Low cost, ubiquitous, mature and reliable infrastructure
6.1.1 Note about Wi-Fi use
Using these products via Wi-Fi is possible but the results are not guaranteed. Wireless
transmissions are subject to perturbations that require data resending which implies unavoidable
delays which are unsuitable for real-time musical purposes.
This is why Alyseum only guarantees good performance when using wired network.
6.1.2 Tips for a efficient Ethernet Network
The performance of an Ethernet network is always related to its weakest link.
● Use the WI-FI only for web browsing, Email, ... and the wired network of your computer for
CopperLan and eventual audio streaming
● For large installations, use an additional network card in your computer to create a network
dedicated to CopperLan and audio streaming.
● For large installations, preferably use Gigabit Ethernet switches to guarantee a better data
exchange
● Avoid Ethernet HUB as these create collisions in messages that could hamper the overall
network performance
● For small installations, if possible, set your IP network on Wi-Fi only, and reserve the wired
network for CopperLan purposes.
6.2 CopperLan
CopperLan offers many advantages:
● Connectivity guaranteed with any hardware/software supporting CopperLan.
● No IP and DHCP configuration, thanks to an address abstraction layer.
● Protocol and networking system for command & control + streaming management.
● Self configuring and Plug & Play.
● Universal remote editing with labels, dedicated data types and high resolution.
● Decentralized work distribution and storage – every CopperLan equipment incorporates its
own server.
CopperLan manages MIDI in a more powerful and flexible than any other technology available.
The benefit of having its own dedicated protocol surpasses the afterthought solutions relying on
TCP/UDP-IP in terms user-friendliness.
