Step 1: Calculate Fragment Sizes Fragment 1 Payload : 1080 bytes (maximum payload that fits within the MTU) Fragment 2 Payload : Remaining bytes from the total message size = 2000 - 1080 = 920 bytes Explanation : Determine how many bytes of data each fragment can carry, given the MTU limits the payload after accounting for the IPv4 header. Step 2: Fragment Details Fragment 1 (First 1080 bytes) Version : 4 (IPv4) IHL (Internet Header Length) : 5 (20 bytes, assuming no options are used) Type of Service : 0x24 (routine precedence and normal delay, normal throughput, and high reliability) Total Length : 1100 bytes (1080 bytes payload + 20 bytes header) Identification : Any unique number, let's use 1234 Flags : Bit 0: Reserved, always 0 Bit 1: Don't Fragment (DF), 0 (since we need fragmentation) Bit 2: More Fragments (MF), 1 (indicating more fragments follow) Fragment Offset : 0 (this is the first fragment) Time to Live (TTL) : 64 (common starting value, decremented by each router on the path) Protocol : 17 (UDP) Header Checksum : Calculated by the sending device Source Address : 200.1.1.2 Destination Address : 64.120.1.253 Data : First 1080 bytes of the message Fragment 2 (Remaining 920 bytes) Version : 4 IHL : 5 Type of Service : 0x24 Total Length : 940 bytes (920 bytes payload + 20 bytes header) Identification : 1234 (same as the first fragment to indicate they are parts of the same message) Flags : Bit 0: Reserved, 0 Bit 1: Don't Fragment (DF), 0 Bit 2: More Fragments (MF), 0 (no more fragments) Fragment Offset : 135 (offset in units of 8 bytes, calculated as 1080 8 = 135 \frac{1080}{8} = 135 8 1080 = 135 ) Time to Live (TTL) : 64 (same as the first fragment, will be decremented similarly) Protocol : 17 (UDP) Header Checksum : Calculated by the sending device Source Address : 200.1.1.2 <li style="text-align

PLEASE use MTU 1100 ... Don\'t just copy from other ..
