Do you use a different vlan for your audio traffic? Or is it just “family convenience”?
As for enabling QoS between RoonRock and the NDxxx, do you think it’ll improve the interframe timing (which is what we want) in the same way as etherchanneling two switches does?
To be honest I never measured interframe timings nor had the need to. And how it affects the client side (the streamer) is still unclear to me.
No, that pic was from when I first got the PD switch, they are on separate shelves now.
I might sell the blue 8TC-L at some point but it’s not likely to fetch much. The CG is a good switch so if I stick with the POE set up I might use the CG in the other room with my Muso. Not sure yet.
Just the latter… my home work use I sometimes use a separate vlan.
As far as QoS, if there is only one dominant flow when streaming, I suspect QoS won’t make any difference.
That’s what I thought, but considering I have never dug into interframe timing related issues I trust your opinion.
Having in mind that interframe timing regularity/consistency is what we seek, does it mean I’d benefit on etherchanneling two switches?
If it helps anyone, I have mapped out how the music playback path within my network is connected, separating WiFi traffic, from other device traffic.
(taken out backup NAS units, printers, networked UPS, AV equipment etc.)
Thanks,
Simon.
The closet. Located in the office below the hifi in the living room. The Unitiqute in the office is sounding especially big and lush today as the source for it is now going through three switches, two of them powered via ethernet, not to mention the Sonore UPNP Bridge through two opticalModules.
I think you may need to hook up both uplinks from a power source switch to power yet a third poE switch. The poE output on the 2960CPD was meant primarily for phones, alarm systems etc not further switches. But you might get it to work.
Why such complexity ? You live perhaps in a giant house, with xxx rooms?
I have only 1 router, 2 Cisco, and nds/555 dr with Melco.
TV is on the router. PC on WiFi. But we have 45 m2 only.
I was told this should work for HiFi purposes which doesn’t have significant power needs. Not sure but I guess I’ll find out.
Not that different - I canned the ISP Router functionality (as it was poor) and put that into Modem mode, so I have my own Firewall and DHCP server.
I then have internet connected heating, lighting, security cameras.
There there are 3 more NAS units (2 RAID1, 1 JBOD) for Music Library backup, Movies/TV shows, Pictures and general files.
There is then some networked AV - AppleTV and Chromecast, networked SOHO laser printer.
There are 3 wireless Roon Endpoints, covering bathrooms & bedroom.
The network is two elements - ‘Backend’ in the Study with the NetGear switches & ‘Frontend’ in the Living space with the EtherRegen switch.
Music library is around 7.2TB, with over 3,500 HiRes Albums and just under 3,000 in CD quality (only a small number of lossy MP3, AAC files)
We don’t live the same. I have no Nas, and no cameras. Only a living room and a room . My library is 700 albums and 600 lps.
But just looking at your system schematic, it looks not simple. Just my feeling Simon.
How/where do you backup your music library to?
Is this not networked, with some level of automated scripts to ensure all media exists in multiple places, in the event of a disk or device failure,
I have a similar sized LP collection, with 700 odd albums, including box sets, works etc.
Back up on memory sticks. And on my pc.
I presume you also have a backup not on the network?!
As an aside, what is the benefit of lights and heating linked to internet?
Yes, off-line backup, with one set in plastic flame proof cases.
Smart heating is very useful, particularly with geo-fencing, adjusting the demand temp based on your location - whether ‘At home’ or ‘Away’ and then distance you are from home, including overseas, where it heating shuts down until you land back at the airport, before you are home. Though couple of times, when away for a couple of weeks and it has been cold, it can overridden remotely to warm up ahead of your return.
The status also drives the arming/disarming of the security cameras. If triggered, you get notified and can view captured footage, to determine if a false alarm etc.
Lighting can also be programmed/operated while away, but the networking is more motion detection & if ambient light levels low, automates lights on, and then off in certain rooms once exited.
Very impressive Simon. Your files are considered as top secret, so you need a very sophisticated system at home. 
I simply have a programmable thermostats, with three different zones, the house can’t freeze, and a holiday mode can keep it in frost protect mode only until the day of my return. Very simple, no thinking about home weather when I’m away - the one thing I can’t domis reprogram if my return home is unexpectedly early, or delays, but that has never happened yet, other than delay by a few hours en-route, when I probably wouldn’t have internet access anyway!
Wow, I thought having my Airport and Apple TV on the same network (albeit twice removed by Cisco switches) as my HiFi was getting too complicated.
+1 on WiFi thermostats, no need to be connected to the HiFi.
Over 15 years of building the music library, and networking it to multiple zones. Don’t fancy having to re-rip CDs, re-process DVD-A, SACD and BluRay rips or re-download purchases.
Just the same as the last 35 years worth of building the vinyl collection and hunting down certain releases & pressings.
Also remember I work in IT, around large scale computing systems, and high volume transaction solutions.
We call it here « deformation professionnelle « . I have not so many albums as you. I keep my cds to rip them again one day by a better ripper, like the Melco. I have sold all my DVDs . No blue rays, no SACD. So easier for me.
