Layer?

[edit]

"Over Ethernet" implies that the audio application sits on top of Ethernet's layer 2. "Layer 1 Audio over Ethernet" is more likely "Audio over Cat 5". "Audio over IP" is just that, no matter what media TCP/IP sits on top of. Since the text also lacks substantial references I'm going to weed this out unless there are any objections. -- Zac67 (talk) 20:31, 20 February 2015 (UTC)[reply]

I'm not sure what you mean by "weed this out" but I don't see a problem here. Layer 1 protocols use the Ethernet physical layer. Layer 2 protocols use the Ethernet MAC layer. Both are audio over Ethernet. Layer 3 protocols are generally IP and there is a prominent link to Audio over IP in that section. Some audio over IP implementations assume IP over Ethernet so it is reasonable to include some discussion here. ~KvnG 20:55, 22 February 2015 (UTC)[reply]
There isn't anything Ethernet on a simple Cat 5 cable. To call it "Ethernet" it would need to use at least the same layer 1 encoding and packet structure, ie. being propagated through Ethernet repeaters/hubs. Running a digital signal of some kind over a TP cable can't reasonably be called Ethernet. -- Zac67 (talk) 21:53, 22 February 2015 (UTC)[reply]
All the systems listed in Audio_over_Ethernet#Layer_1_protocols use an Ethernet PHY so they use Ethernet electrical and byte encoding but not necessarily Ethernet packet structure. ~KvnG 15:15, 24 February 2015 (UTC)[reply]
Thanks for checking this out. Apparently, I was a bit jumping to conclusions a bit too quickly – however, at least RockNet doesn't seem to use Ethernet, just Cat5 cabling. I'll check them out and move those to §Similar concepts. -- Zac67 (talk) 20:31, 25 February 2015 (UTC)[reply]
