Re: [manet] Why the WG Reactive Protocol to be Compatible with another?

["Charles E. Perkins" <[e-mail]>]

Hello Jiazi,

I do not agree that the protocols are all that different.

I did not declare that AODVv2 will be compatible with LOADng. Instead,
what I have said all along is that we should make the effort to achieve
compatibility.  This means to make the comparison and to resolve
differences.  I have agreed to make a comparison draft, and I have tried
to enlist the aid of another LOADng author in the effort.  Once the
comparison is made, we can have a discussion about each point of
difference, to decide upon the best resolution.  I am pretty sure that,
if we do this with honest effort, we will get a better result overall.

Do you want to help?

Regards,
Charlie P.

As one who participated in all LOADng interop tests and know dymo draft relatively well, I can say that a lot of effort are needed to make DYMO and LOADng compatible, not to mention the interop tests needed to verify the compatibility (at this point, I have no idea if there is DYMO implementation, so I'm not even sure if such test is possible).
