Do you know what the similarities and/or differences of your implementation of ethernet re my Resolution Audio Cantata?
I Googled the Cantata to learn about it. The Ethernet is used as a method to extend the range of USB (using pont neuf), so this not really Ethernet DLNA or other protocols. Even when a router is used, the Ethernet is used simply as an extension for USB asynchronous protocol to gain greater distance.
My Ethernet does not have USB protocol underneath. It has DLNA instead. It is using packets to move data, just like storing to a disk or sending email using Ethernet. However, the DLNA protocol makes sure that all of the packets are re-assembled in the endpoint and spooled from a FIFO and that the endpoint FIFO never runs out of data. It also identifies the file-type and sample-rate so the hardware knows what to do. The DLNA protocol is supported by many mass marketed devices from companies like Panasonic, Oppo etc... The important thing is that two decent audiophile players support DLNA, namely Jriver and Audirvana+.
DLNA is not compatible with all players. Amarra does not support it and Roon does not support it. Roon uses a different Ethernet protocol than DLNA. The queueing model of DLNA and Roon's RAAT are different and non-compatible.
