Quick and Dirty Python UDP Stress Test

Description:

This is a pair of scripts that serve to do a rough 'stress test' of UDP capacity between two points on the network. The output is in kilobits per second.

Platform:

Should work anywhere that Python works.

Output:

Client:

C:\Python24>python udp_stress_client.py

Starting client end.  Control-C to quit.

Our target:
udp_stress_server.py running on localhost port 8105


Enter number of bytes to send and the number of times to send them:
(for instance '100 10' to send 10 bursts of 100 bytes each)
