I have no previous ISDN experience, so I hope someone here can
enlighten me a bit about a problem I am facing.
One of our customers is planning to upgrade an aging 2400 bps RS232
based network to ISDN. The system is composed by a central node which
broadcasts periodic messages (about one 50 bytes message per second)
to some 100 remote stations.
The central issue of this revamping would be to keep the broadcasting
capability. The traffic on that network is not heavy but they have
many stations and they plan to add more so we have some scalability
I was thinking may be IP multicast could be a good candidate, but
- It looks like ISDN in and of itself does not support multicast.
- Apparently, this can be worked around by adding a router capable
of multicast tunneling.
If all the above is correct, and considering that apart from
the multicast traffic there will be some TCP traffic too,
are the following statements correct:
1) I need to add a router at the central node to enable
2) There's no need to add anything at the remote nodes
3) I assume this tunneling issue is well known and most
routers support it
4) suggestions for a good router (possibly not costing
an arm and an eye)?
5) Is there anything that I am overlooking?
Sorry if some questions may sound silly but as I said, I know
zip about ISDN.
Thanks for any help/suggestions,
I know you can't speak, I know you can't sign
So cry right here on the dotted line
