Hello,
I have been tasked with coming up with solutions for an audio broadcast system for use over the network. My biggest problem is finding an intrusive alert system so that all networked personnel will have the audio message simultaneously forced on them. We have a NT & 2000 based 100TX Ethernet network utilizing nortel routers. We don’t seem to have multicast capability yet. Can anyone suggest an off the shelf solution or some relatively simple ways to develop the solution? I have already created a client application that responds to specific UDP commands but I want something thats designed to be robust enough for an Emergancy Broadcast system.
I think that it needs to be a client program but are there library calls that I could somehow monitor for specific broadcasts without adding much overhead? How would I discern what is something I am interested in and/or how can I trigger a unique network broadcast. Is there a way of handling this with ICMP? When I tried to use MS internet components with VB (wskClient with UDP) I found that I had to cycle through all of the IPs addresses for my agency. It looks like a builtin limitation to the control but I could be missing something.
A couple of comments:
Theissue with whether the speakers are on or loud enough is a business rule and so is really for management to deal with. However, if I knew that all PC’s come with builtin piezo speakers and if I knew that these speakers were capable of producing realtively loud and yet intelligible speech then I guess I should look into that as part of a possible option.
It goes without saying that a popup message will display the message at the same time as the sound is being delivered.
I look forwardto our discussions on this.
