Field Description
Configure Destination
RTP Relay Check box to automatically configure a destination RTP relay to
stream the video conference over RTP. Instead of going to the
RTP Relay Overview page, you can simply check this box to run a
wizard that automatically creates the destination relay.
A destination RTP relay forwards a multicast stream to local users
in an IP network using an auto-generated .sdp file that becomes
part of the URL to the stream, for example:
http://
<dme_ip_address>/mystream.sdp
.
When clients open a player and
point to the .sdp file with a URL, the player will tune into the
stream.
Be aware that if you change the setting on this page (for a
previously created relay) you will actually be creating a new relay
and leaving the old relay in place. Consequently you will need to
open the RTP Relay Overview page and manually disable and
delete the old relay.
For best results, if you need to make changes, edit the relay on the
RTP Relay page rather than on the VC Gateway page.
Relay Name Enter a unique name for the relay.
Destination IP Enter a valid multicast address for your network, for example:
239.22.118.72
Base Port Use this parameter when pushing the stream to another DME.
The base port will be incremented by 2 for each RTP stream. Use
numbers that are not already being used for the entire SDP
sequence set.
Output SDP File Enter a name for the auto-generated .sdp file.
TTL Specify the number of routers the multicast stream will pass
through before it stops propagating over the network. Range = 1–
255.
