if a sender sends several udp segments to a receiver, how can the receiver find out whether the segments arrived in the same order as they were sent? a. the receiver can check the sending times of the ip packets that carry the udp segments. b. the receiver has no way to find out such ordering information, unless the application that generates the payload for udp puts such information in the payload. udp by itself does not care about the ordering of segments, they are sent as independent datagrams. c. the receiver can check the sequence numbers in the udp header.
