Hi,Can you tell me what the "sun display grid" is referred to in the attached posting
Thanks Paul

Hi Jakob,I've been using a Sun Ray desktop over a broadband DSL for over 5 months now. The desktop is actually hosted by Sun's display grid folks, and I think this kind of hosted service may eventually become something people can subscribe to (perhaps through an ISP or telco).I will publish a longer article about the experience shortly, but here're some brief comments:Overall, the experience is completely usable for most typical desktop tasks, i.e., running most desktop applications. As has been noted, there is a slight latency in screen updates, but you can get used to that, and it doesn't interfere with usability.With multimedia applications, such as watching video, the experience is not as good. It think a future version of the Sun Ray software will address this issue.Bandwidth is not going to be a limiting factor in the user experience, because the SRSS 3.1 uses very little bandwidth. In fact, we measured that during typical use, the Sun Ray took up only about 20% of the available bandwidth of a DSL connection ( < 200 Kbps).Latency is a much bigger issue. It's also more complex. In general, a fast server will help, since some of the latency may come from the server's (in)ability to push updates to the client and to process the protocol commands, not to mention running the desktop apps. It might be a good idea to run the SRSS on a different server from the server running the apps and the desktop.Overall, the experience is really amazing. This thing has a lot of promise, and especially as I think the Sun Ray communication protocol may be further optimized in order to provide an improved user experience.-- Frank Markolf Gudjons wrote:Hi Jakob, On Tue, 18 Oct 2005, Jakob Oestergaard wrote:Just curious; what is the approximate bandwidth and latency from the side of the VPN where your SunRay sits to the SRSS ?I tested it with 1 Mb/s symmetrical and an average latency of around 50 ms.And how do the screen updaets feel, interactively? (eg. switching between virtual desktops or other things that require large screen updates)There is a difference, but it is entirely usable. Screen refreshs likeswitching between desktops show the tiles being updated across the screen, but it's not a real problem. Playing MP3s using xmms works nicely, with nodropouts.I was hoping to be able to use a SunRay at home - I have a 6Mbit symmetrical line, and I guess a ping of around 20-30 ms.That should work nicely.No VPN yet though - will need to get that sorted before I can do any testing. I'm really curious as to whether that will work.I see no reason why it shouldn't. Just make sure when selecting your VPN product that you can use it in network extension mode, meaning you are able to route traffic from your internal network through the VPN client and the concentrator into your Ray network. In the case of the Cisco VPN, this means having to purchase a HW client because the software client doesn't allow you to do that.If you (or anyone else who's using SunRays from home broadband connections) could give a little info on how the desktop "feel" is in such a setup, I'd greatly appreciate it.I'd say it's definitely usable.
