Because it travels in UDP, an RTP message can be duplicated. Does a receiver need to keep a
copy of all previously received messages to determine whether an incoming message is a
duplicate? Why or why not?
Solution
No,a receiver need not to keep a copy of all previously received messages to determine whether
an incoming message is a duplicate or not.
In a communication system that transmits messages (an original message followed by one or
more copies of the original message), a selective call receiver which receives an original
message and one or more copies will display only one of the received messages and discard the
others without displaying them. This is achieved by storing in a memory the identification tag of
the message that was displayed and deleted. The identical identification tags carried by later
copies of the same message are compared to the stored identification tag. If a match is found, this
indicates that an earlier version of the received message has already been displayed and
deleted,which result in ignorance or discarding of duplicate files..
