Clarified in the other mail, good. > Here's an idea: what if we pad the IHU response instead of all hellos?

The Hellos are periodic, so the overhead is constant. The number of IHUs is proportional to the number of neighbours, so there might be arbitrarily many of those. I'm pretty sure it doesn't matter much in practice, but at least with Hellos the amount of overhead is easy to predict. -- Juliusz _______________________________________________ Babel-users mailing list [email protected] https://alioth-lists.debian.net/cgi-bin/mailman/listinfo/babel-users
