Steam streaming over 10Gb fiber LAN.

[Construct]

Im curious to see how this runs over higher bandwidth lower latency medium like 10Gbe fiber in a LAN. I know this is not common place yet but eventually it will trickle down to home users.

10GB is totally not needed and will run as smooth as 100 mbit ;-) :D Even 10mb will be enough to stream when compression used. But the more the better :)

You are missing the point of In-Home Streaming.... The Streaming doesnt happen over the internet it takes place between 2 computers in your home. Thus it does not matter what the speed of your ISP.

It will make no difference whatsoever, man. The video produced by the streaming system is not going to be any higher than ~100mbps, and will almost definitely be much lower than that. Latency won't be any different either as the bottleneck there is the rendering pipeline rather than the network. (If we're talking about copper vs. fibre, of course. Wi-Fi vs. fibre would see a difference... but then so would WiFi vs. copper).

Yeah, the difference between a 1Gb copper network and a 10Gb fibre network will be precisely nothing.

This.

I dont think i am. I am talking about using 10Gbe fiber to connect a Steam streaming box directly to client. Where this matters is 10Gbe fiber has considerably lower latency then consumer grade wifi or copper tp. From what i have read online it sounds like bandwidth is not an issue in term s of streaming but latency is thats where 10Gbe over fiber would have an advantage.

Fiber cabling by it's self is far to expensive for the average home network,plus you need a switch that can do fiber and your systems will need the proper network adapters.Then again if your nuts (like me) and have the cash to burn(not like me) then go ahead and run fiber. It would be nice to see the difference in performance.

Spoken by a person who doesn't know the cost of 10G fiber or optics.

Construct is correct. Fiber has lower latency than copper. Instead of microseconds, it's nanoseconds. You can see this in, for example, Arista's lineup of switches. Compare the latency of the 7048 GbE switch (copper) with 7050 10GbE switches (copper, fiber uplink)) and 7150 10GbE SFP+ switches (fiber):

Now, would this improvement in latency be noticeable for streaming games from your computer in your bedroom to your htpc in your living room? I have no idea, but would be very fun to test. :)

Unfortunately all that difference in latency would mean precisely nothing, PCI busses wont be able to process the data coming in at 10GBe, unless you are running on a server... but that would be noise prohibitive.

In the home you will have higher latency in the TVs processing than in the network.

[El Botijo]

Somebody mentioned WiFi. Of course anything that is wired is going to have lower latency and is going to be more predictable.
100Mbit/s might be enough for any h264 encoded stream (that is the most common encoder you might find inside any phone SOC or GPU). Blurays are encoded I think at max 40Mbit/s. Even using extra bandwidth instead extra processing cycles to have better quality, I wonder if you ever would need more than 60Mbit/s.
Those are my two cents.

[Neverendy]

NEVER!

Very true, but everyone expects them to open it up to internet streaming eventually. Personally I'm going to hop on my VPN and try to do it that way.

Lucky for me i do have a server and almost no periferel card uses PCI anymore almost everything has transitioned to PCI-E which only requires a PCI-E 1.0 4x connection to provide enough bandwidth to accomodate a 10Gbe adapter. I already have the hardware and am looking forward to testing it out with steamOS.

It's not a suitable test for your hardware. You won't notice the difference between that and a regular home Ethernet network. Home streaming has been lag free for a while now, even over WiFi.

At 720P with 2 channel audio. Im sure it will work just fine over 1Gb network, but I am very curious to see how it performs with 1080p 5.1 Audio or even further down the line with 4K resolutions. A lot of people seem to be under the impression that steam streaming will not use a lot of bandwidth. What i have read in regards to Nvidia Shield streaming which steam streaming is based off of it will require a decent amount of bandwidth. In fact the slowest wi-fi router that Nvidia Shield even supports is a 600mbps router. So with a minimum requirement of 600mbps for a reliable and enjoyable experience at 720p what do you think will be required for 1080p which has nearly 50% more pixels?
