hi all,

Does anybody have any idea about the throughput of the tcp connection?

thanks

    Hello Xiang Chao,

    I am not certain what metric you are looking for. TCP throughput would be dependent on which TCP stack you are using along with external hardware considerations. Generally speaking, the built in ENET MAC is a 10/100 MAC.

    Hi Davenport,

    With the built in MAC and LwIP, what is the max throughput in your estimation?
    Is 10MB/s possible?

    regards

    Hello Xiang Chao,

    We have not officially characterized the bandwidth capability of the combination of the HW MAC and the SW LWIP example/reference code. A colleague mentioned that they have done some analysis and had no issues surpassing the 10Mb/s rate; but, this is not an official endorsement of those results nor any implied guarantee that your application would achieve the same results. The bottom line is that you would have to implement it and test it yourself. If it helps, the the device datasheet does explicitly state that the MAC hardware will perform to these levels but this doesn't take into account any SW implementation.
