Detailed explanation-1: -Packets can arrive out of order. That can happen especially if two packets follow different paths to the destination. Packets can be corrupted, which means that for some reason, the received data no longer matches the originally sent data.
Detailed explanation-2: -When a host system initially sends a packet, it looks up the packet’s destination address in its routing table to determine if the destination is on the local network. If yes, the packet goes directly to the host with that IP address. If not, the packet goes to a router on the local network.
Detailed explanation-3: -What Causes Out-of-Order Packets? Multiple Paths: Out-of-order packets can be caused by data streams following multiple paths through a network (such as traffic traveling through the Internet), or via parallel processing paths within network equipment that are not designed to ensure that packet ordering is preserved.
Detailed explanation-4: -User Datagram Protocol features It allows packets to be dropped and received in a different order than they were transmitted, making it suitable for real-time applications where latency might be a concern. It can be used for transaction-based protocols, such as DNS or Network Time Protocol (NTP).
