I have an IP packet of header length of 20 Bytes and data length of 4096 Bytes. The maximum transfer unit of the network is only 1500 Bytes. As I understand fragmentation, the fragmented packet will look like below.
FRAGMENT 1 will carry 0-1499 Bytes of data.
FRAGMENT 2 will carry 1500-2999 Bytes of data
FRAGMENT 3 will carry 3000 - 4096 Bytes of data
The fragment offset field values should be as below.
FRAGMENT 1 - 0/8 = 0;
FRAGMENT 2 - 1500/8 = 187.5 (Does this means that we will add 4 Bytes of padding and set the fragment offset field as 188? From my understanding of networking, this should be obvious way to do it but I can't seem to find any info on Google to support this.)
FRAGMENT 3 = 3000/8 = 375.
Any suggestions would be appreciated.
