Invalid retransmission

[kirill-782]

conducted an experiment: wrote a program that, through Garena on TCP, sends packets to it. The packet is 8 bytes (4 headers and length, 4 more is an integer that is incremented by 1). The packets were transmitted every 200 ms. If the packet does not arrive within 1500 ms, a notification is displayed.

P.S. Packets are lost almost immediately so that every number that comes up is output.

Client log The number in brackets is milliseconds since the start (client log)
