Requirements 2/3 RQ 5: Interoperability with SEND The optimized DAD mechanism SHOULD work when SEND (Secure Neighbor Discovery) is used. It is desirable that the SEND and DAD Optimization work are closely coordinated so that it DAD Optimization could benefit from SEND and vice versa. RQ 6: Simultaneous Operation with DNA It SHOULD be possible to use optimized DAD addresses even before the DNA process has been completed. In other words, the hosts SHOULD be allowed to send packets to a newly attached link with the assumption that the link may be the same one that was previously used, without needing to wait for the DAD and/or DNA procedures to complete. Such practice MAY result in packet loss, and it MUST NOT cause packet storms or excessive traffic in the case the newly attached link is not the previously used one and steal service from another node in the case that there is a collision, in a way which is not recoverable using [RFC 2462] DAD defense. |
