Port
Set the port number used for router to receive the streaming data from the product (No need
for unicast). ‘18888’ is set for video data of 1st stream and ‘28888’ is for video data of 2nd
stream.
TTL
Set the TTL value. If you set 1 for TTL, it means the packet will pass only in a subnet (No need
for unicast).
What is TTL?
It’s the abbreviation of Time to live. If data is sent out from the encoder via network and all of
the packets are alive permanently on the network, it will cause the big network load. TTL helps
to reduce the network load by controlling the time of staying on network. For example, if you
set the TTL as 50, the data will be deleted after passing by 50 routers.
