66AK2G12: NDK UDP send no-copy

Part Number: 66AK2G12


Dear All,

In my application I need to send UDP packets to multiple destinations. To some destinations with some delay.

I want to avoid unnecesary payload copies in the IP stack.

I know that NDK provides sending without copy for the socket type raw. But I need to do the ARP address resolution. So I think I cannot use it for my application.

Does anyone have any idea how to achieve this?

Kind Regards,

Bernhard

    I realized that even with a nc variant for UDP sending a problem remains.

    For the RAW socket sendnc() the packet is forwarded to the NIMU driver. Therefore I can't reuse the packet handle for re-sending it to other destination.

    Nevertheless if someone has an idea let me know.

    Hello Bernhard,

    Please note that TI has stopped supporting NDK based SW development for K2G devices. Sorry for not being able to help here. One thing that you can try is to search from the forum and see if there were similar questions asked before.
