Yet another network switch.  This one is a modified Cisco SG110D-08 for $395.  Anybody tried one?

Goodness, what's next - testing to see which switch is best at playing?

Here we go:

Improve video playback as if playing from HD directly? Does this mean the modified switch somehow convinces the OS to cache the video and audio stream from Netflix? Prime Video, Hulu?

 

Reduce packet fragmentation? Like below (from an MDF I put in in August):

“It’s like playing from hard drive directly.”

Haha, talk about not knowing your audience. A hard drive near my server! Eek!

Since people mentioned about EtherStream here making some statements, I'd like to clarify something.

 

“It’s like playing from hard drive directly.” is a message I received from clients using EtherStream with audio/video streaming applications. And EtherStream's main goal is to improve streaming media closer to ideal local storage media.

 

As for gaming improvements, average ping was decreased from real tests. Please don't confuse packet fragmentation with packet lost or error. You don't do disk defragmentation because it always has read/write error on data with fragmentation on hard drive.

If you think you measured lower ping times with your modified switch compared to a stock unit of the same model, your test setup was flawed somehow and you actually measured something else. The modifications listed simply cannot alter the propagation delay through switch.

 

The claims about fragmentation are even worse. An Ethernet switch does not fragment packets, nor does it reassemble them. Routers do that. This is a simple unmanaged switched. All it does is receive Ethernet frames and forward them to the correct port.

 

You really ought to be more careful with what you claim. If you're going to make stuff up (and you clearly are), it would be wiser to stick to unverifiable things.

It'd be easier for client to verify themselves. So far I haven't seen anyone failing to see what I claim yet. I agree that making claims without proper measurements to backup will not be enough to satisfy everyone. I convey something I believe in approach I can do myself and there's only so much I can express.

 

However, it's not like I have to satisfy everyone. I develop this solution for my own personal use and share to market for those who have the same issues. I've been doing things this way since founding Fidelizer software and I won't plan to change my approach for better sales figure. I'll remove gaming section since it's not really aimed to reduce ping then. It's just what my brother told me after implementing for a while.

 

Also, I have no idea who you worded it as if I suggest ethernet switch will fragment packet. I never said things like that and packet fragmentation is common occurrence in network. I explained in my website how network switch can improve the situation about packet fragmentation actually.

Measuring the delay through a switch is not easy to do with any accuracy. On a simple simple LAN, most of the ping round-trip time is contributed by the endpoints, not the switch, and the tiny amount it does add is easily lost in the noise.

You said your switch "can reduce packet fragmentation." Those exact words. Oh well, you removed it, so there's no point discussing it further.

Well, you probably won't find anything worthwhile from my products if you believe in bits are bits. Maybe it'd be easier if you pretend to forget everything you learn so far and try Fidelizer software without thinking too much about it, and joy enjoy the music. If anyone want to read people trying EtherStream, you can read from this page below.

Please provide a video of said tests. I'm all stocked up on switches from $30 (Cisco 2960-TC 8 port) to $23,000 HPE 8230's.

I'm not confusing anything. I just posted a single trunk off of an MDF that showed ZERO errors. It's a trunk that services 194 wire ports and 16 WAP's. POE, 802.11x, AAA, SNMP, PIM, etc...

Packet fragmentation happens at Layer 3. Runts, FCS error, CRC error's are FRAME errors and happen at Layer 2.

You are so incredibly wrong here. Switches do nothing with out of order reassembly. For the most part modern switches are Store and Forward.

 

TCP end point hand-shake and windowing happen at layer 3. IP is layer 4 and other higher layer protocols and application deal with re-order and assembly.

Are you sure you didn't get things mixed up a little there? Packet fragmentation and reassembly happens at the IP level, which I thought was layer 3. TCP sits on top of that and provides a reliable, ordered data stream. If MTU discovery is working correctly, fragmentation at the IP level should be infrequent.

You're correct. Windowing and Handshake happen at L4 (TCP). I simply flipped it by mistake.

I see. it seems IT specialist will understand fragmentation as technical term so some wording can cause misunderstandings. Maybe it's better to address this as the effect from packet fragmentation causing less data integrity with better explanation. I have corrected the information in my product page now thanks to you guys suggestions.

Well, they didn't test with Tidal/Quboz. I developed EtherStream to resolve the issue of streaming media sounding worse than local storage. For 4th place isn't that bad for current condition where network improvements can only reduce local interference at best.

 

I hope they'll make round 2 with Tidal/Qobuz streaming. For people who find streaming media sounding worse than local storage including NAS, that'll make more noticeable improvements for some products. Even with my Nimitra and EtherStream itself won't bring big wow effect until they play Tidal/Qobuz.

 

I guess Cisco Meraki switch sounding better than audiophile one costing more would be quite shocking for some. From my experience, linear power supply upgrade also affect sound quality on local storage a lot enough for some people to use audiophile power cables costing more than LPS and switch itself combined.

Tested EtherStream in my friend syst consisting of expensive cables , Odin 2 , Ch Precision with PsU , Trinity pre & power amp. Compared to the stock Cisco switch ( same as EtherStream’s stock Cisco except 5 ports ), major and clearly audible improvement .

In my system with Nimitra Music server with all Vitus Masterpiece component , there was improvement but not as dramatic as in my friend syst . Probably because his NAS was connected to EtherStream where else my SSD was connected directly to 1 of Nimitra USB port . 
I did compare it streaming thru Tidal . Even though it better compare to using stock switch , I prefer the SQ streaming thru local files .

How good is Nimitra ? Not bad at all considering the price . I used to play with Aurender W20 connected to MSB Selectl . For reference 


Happy listening. Its all about quality music

Thank you for sharing your feedback with us. It's really rare to find people sharing computer audio experience with very good systems like CH Precision and Vitus. I hope we'll get to see more computer audiophiles sharing their experience with more elaborated systems. :)
