python3 udp_latency.py -s -b --ip --port --verbose --save

Argument	Description	Default value
-c	Client	N/A
-s	Server	N/A
-f	Frequency of sending packets in clients, unit is Hz (number of packet per second). -f “m” means constantly send UDP packets in maximum bandwidth	1
-n	Size of sending packets in clients, unit is bytes. Notes that it is the frame size on wire including IP header and UDP header, the packet size should be within (44, 1500].	1500
-t	Client running time, uint is second. The server also stops when client stops running.	10
-b	Buffer size in server.	1500
–ip	Remote ip.	127.0.0.1
–port	To port and local port for client and server respectively.	20001
–verbose	Whether print the testing result each iteration.	True
–save	File path to save testing result.	./result.csv
