Description: Packet duplication refers to the occurrence of the same packet being sent multiple times across a network. This phenomenon can result from various causes, such as network errors, incorrect configurations in network devices, or even malicious attacks. In the context of networking, packet duplication can generate congestion in the network, as the same packet consumes bandwidth resources repeatedly. In terms of DDoS protection, packet duplication can be indicative of an attack, where an attacker attempts to flood the network with multiple copies of the same packet to overload server resources. In a LAN (local area network), packet duplication can affect the efficiency of communication between devices, causing delays and data loss. It is crucial for network administrators to identify and mitigate packet duplication to maintain the integrity and performance of the network. Monitoring and traffic analysis tools are essential for detecting this issue, allowing administrators to take corrective measures before it becomes a larger problem.
