I'm trying to find an example to show where data is sent from a server and is pushed to a/multiple clients which are updated immediately, i.e. the client doesn't make requests for updates. It doesn't matter whether we're talking mobile, desktop or whatever. An even better example would be where there were multiple recipients for the same message. It doesn't matter what the data is or the context it's used in, only the immediacy of receiving it. I was thinking that there might be some example in finance and the stock markets, but I haven't been able to find any through googling.
IM clients are a great example of this and are on my list of one ;)
If anyone works on applications of this nature or knows of particular implementations, can you give me a quick run down of the use case and if it's commercial software the name of the software.
This is all basically for research purposes so doesn't have to be particularly detailed.
If anyone can help, thanks.
EDIT - Granted the question is vague. Doing some concepting so need some examples. There must be a huge amount of apps that work like this.
Obviously "immediate" is never going to happen..... light-speed, sir ;D
Your question is a little vague though, could you maybe help describe a little more what you want, or why you need this? I can name a million things that act in that way, from skype, ts. ventrilo etic, to IM, submitting a webform, clicking a "download" link (have you ever waited more than a half second for it to start downloading?). – Dmatig – 2010-05-12T09:43:15.750
@Dmatig. Well certainly not imediately as in lightspeed :P. But IM and skype are the type of things I'm after as the server sends information and the clients recieve it instantly. I suppose, what i'm really after is examples where a message can be sent from a server and clients are pushed the data. Browsers don't work that way as the user must make requests for the data. Will update my question to reflect this. Cheers – James Hay – 2010-05-12T09:52:42.173
too vague a scenario. by your description, a centralised game server fits the bill. All gamers (client machines) connected to the server will receive game event data "immediately" as they play the game. – icelava – 2010-05-12T09:55:44.663
@icelava Thats the kind of stuff I'm after. It's a vauge question because all I want is vague answers. I'm in the process of doing some concepting so want some examples to show – James Hay – 2010-05-12T09:58:39.147
You should change this question to Community wiki - it's not a question that can be "answered" as a true solution - too open for discussion. – icelava – 2010-05-12T10:03:09.527
@icelava fair shout. I should have known that from Stack ;) – James Hay – 2010-05-12T10:05:33.703
