In this question to fragment the original 6000 bytes packet into smaller fragment with the mtu of 1500 bytes, we can use the ip fragmentation process.
00:13
So, the identification field, flags, fragment offset and other fields in the ip address are used to manage fragmentation.
00:23
So, given that the ip datagram header is 20 bytes and the mtu is 1500 bytes.
00:29
So, we can calculate the number of fragments and the size of each fragment.
00:36
So, here let's calculate the number of fragments.
00:39
So, in this fragment details, identification field is 1, 2, 3, 4 constant for all fragments.
00:48
Fragment 1, flags m1, mf1, df0, reserved 0 and offset fragment is 0.
00:59
So, payload size is 1480 bytes.
01:04
For fragment 2, it is same as payload size is 1480 bytes.
01:11
Now, coming to the fragment 3, flags mf is equal to 1, df is equal to 0 and reserved is equal to 0...
