Header of Packet in Datagram Network
In a datagram network, each packet has a header that contains necessary information to route the packet from source to destination. The header of the packet is added by the sender and remains unchanged throughout the journey of the packet.
Remains Same in the Header of Packet
Among the various fields in the header of a packet, the destination address remains the same in the header of the packet in a datagram network during the entire journey of the packet. This means that the destination address is not modified by any intermediate routers or nodes during the transmission of the packet.
Explanation
When a packet is sent from the source to the destination in a datagram network, it passes through several intermediate routers or nodes. Each router or node reads the destination address in the packet header to determine the next hop towards the destination. The router or node then updates the source address in the packet header with its own address and forwards the packet to the next hop.
However, the destination address in the packet header remains unchanged as it is used by every router or node to determine the next hop towards the destination. If the destination address is modified by any intermediate router or node, the packet may not reach the correct destination.
Conclusion
In summary, the destination address in the header of the packet remains the same in a datagram network throughout the journey of the packet. This ensures that the packet is correctly routed to the destination without any modification to the destination address.
