Answer
The senders PC is using UDP protocol
Explanation
UDP is the User Datagram Protocol which is used as an alternative communication protocol to the TCP which is used primarily for establishing low latency and loss of tolerating connections between applications on the internet UDP is normally used by the programs running on different computers on a network. Its purposes is to send short messages which are datagrams. It is not much reliable because of its occasional loss of packet. Due to this packet loss  the recipient is not guaranteed that the data being streamed will not get interrupted. This is because If a router on the Internet starts getting overloaded, or a packet gets corrupted due to interference or anything, the packet will be dropped unlike the TCP (Transmission control  protocol)which resend the packets and keeps re sending. The UDP does not resend the packets which are dropped. Once they are dropped that all.
