This chapter will detail the interfaces involved in the network protocol layer.
This interface must be implemented by all network protocol handlers.
This interface must be implemented by OSI transport layer protocols.
This interface must be implemented by OSI link layer protocols.
To register a network layer, the network layer class must be specified in an extension of the "org.jnode.net.networkLayers" extension point.
This is usually done in the descriptor of the plugin that holds the network layer.
