Re: Streaming from the 323

DNS-323 connected to d-link switch 10-100-1000 , PC with marwell gigabit ethernet. The sat receiver is recording ts file to dns over nfs connection. The pc is playing the ts file over samba connection. It uses no more than 1% of 1G link.
The speeding up playing to play next frame with step 1second makes using the link max in 15% of the link - it is 15Mbit. I was never be able to see faster streaming. It can be max performance of seagate 1T disc in dns-323 or samba connection. (what nfs client for windows is the best ? excluding usnix extensions for windows from microsoft)
The same reviewing in fast speed (each 1s) from seagate in the PC system is a small bit better. The result is more linear. The same by ethernet is not the same linear but is not bad in mostly parts of time. Sometimes the speed is slowing , but the max transfer over internet is not decreasing.

I have tested the same with SATA 500G samsung disc. The result is always a big bit worse. The samsung is not good for work with data over network connection. It can be used only as repository of file and nothing else.

Do you have any comments ?

Re: Streaming from the 323

what about wireless streaming (over 802.11n)  Anybody have any success with that?
I tried using DNS linked to the router through Gigabit ethernet, then streaming to the computer over 802.11n... but if songs play well (with a lag at the start) videos don't play well AT ALL...

Is this an observation about streaming over 802.11n or streaming from the DNS-323?
What was the performance like if you connected directly to the switch rather than using wireless?
What wireless router were you using?
What wireless card were you using?
What other wireless networks were there in the vicinity - not necessarily 802.11n, any 802.11 spec?

The reason why I ask is that in my opinion 802.11n is still more hype than reality - and judging from the fact that the spec is now in draft 3 and the ETA of the final spec has been puched back yet one more time (now estimated at June 2009), there is still a lot of work to be, especially in the areas of inter-brand-interoperability, backward compatability, and last but by no mean least, n-spec operation (40MHz channel width) in the presence of existing 802.11b/g networks (20MHz channel width).

A bit of both really...
Streaming from the 323 over the air using 802.11n.
The performance was good when i was connected directly (no lag for music, somewhat of a lag at the outset for video)
I am using a WNR854T and on the computer side (Macbook pro w/ 10.5.1), Apple's 802.11n implementation.
One wireless network next door.

Re: Streaming from the 323

Since the performance was "good" when connected directly, I would guess any other issues can be attributed to the 802.11n connection.  It would be interesting to know how that compares to the older 802.11g spec.

Re: Streaming from the 323

Yup... will endeavour to look at that this week end (with Wireshark or other...)

Thanks

Re: Streaming from the 323

ha. looks like it was a router problem. Traded in the Netgear WNR854T for a TrendNet TEW 633 GR... night and day. Videos play no problem at all!!!
That netgear is to be avoided like the plague...

Re: Streaming from the 323

Streaming from the DNS-323 is perfect. I have two DNS-323 connected via a (very cheap) netgear GS108T to a dlink DIR-655 802.11n router.

I record video (.TS) using three dbox2 and two dreambox dm500 in parallel using NFS (typically two devices record at the same time). Playback is done via Netgear's EVA700, EVA8000, dlink's DSM-520 and Zyxel DMA1000 as well as PC/Notebooks and Philips SLA5520 (audio only).  I use NFS, SMB, UPnP for playback - whatever fits best for the client!
All devices are connected via gigabit, except my notebooks and the SLA5520. The notebooks connect via 802.11n.

Video playback (also HD) works perfectly - with a maximum of two streams playing back at the same time (sometimes while other content is being recorded). Streaming performance of the DNS-323 beats even my ReadyNAS ... but I have not tried to optimize the ReadyNAS.

I have issues due to bad or instable firmware (netgear EVA700, EVA8000) or due to bad implementation of UPnP (Nero Showview, EVA8000).


By the way: for dbox2 users the GS108T switch performs very well as it supports manual QoS settings and specific link parameters.
