Official TCP Full speed benchmark
This project represents a the official TCP Full speed Benchmark for the PicoTCP library.
The mbed board is sending and receiving one Megabyte from/to the other side and we measure how fast it does that.
TX+RX Throughput: 2097152 bytes in 1 seconds (12.410)Mbits/s
The python script used (which you should rename it to PicoTCP_Official_TCP_Full_Benchmark.py)

This test is based on the following libraries
