Hi!
Let's see the following paragraph of section 4 in RFC2460.
" Each extension header is an integer multiple of 8 octets long, in
order to retain 8-octet alignment for subsequent headers. Multi-
octet fields within each extension header are aligned on their
natural boundaries, i.e., fields of width n octets are placed at an
integer multiple of n octets from the start of the header, for n = 1,
2, 4, or 8.
"
here n is the width of the fields in extension header;
another paragraph of section 4.2:
" Individual options may have specific alignment requirements, to
ensure that multi-octet values within Option Data fields fall on
natural boundaries. The alignment requirement of an option is
specified using the notation xn+y, meaning the Option Type must
appear at an integer multiple of x octets from the start of the
header, plus y octets. For example:
"
here, n is the multiple of the width of field in extension header,x is the
width of the field.
I would like to rewrite the former paragraph as:
" Each extension header is an integer multiple of 8 octets long, in
order to retain 8-octet alignment for subsequent headers. Multi-
octet fields within each extension header are aligned on their
natural boundaries, i.e., fields of width x octets are placed at an
integer multiple of x octets from the start of the header, for x = 1,
2, 4, or 8.
"
Please give me your points,thanks.
