Hi Pete Appreciate the review, I posted revision 06 now. I made the two editorial changes you suggested. Your suggestion is an improvement, and I agree about the capitalization as well. When it comes to padding. I want to keep it as is, to minimize packet size. We are not using padding in for instance the pim protocol either. I'm aware that some architectures will not allow accessing an unaligned 16/32/64 bit value, I think I've seen segmentation faults on SPARC, or will take a performance hit. To be safe one may need to for instance use memcpy to copy the values into separate aligned variables.
