Which packet replay method allows sending individual packets with header fields and payload details?

The method that allows sending individual packets with header fields and payload details is known as Single Packet. This approach focuses on the manipulation of specific packets, enabling a detailed examination and precise control over the packet structure. Each packet can be crafted with its unique header fields and corresponding payload, making it suitable for testing the behavior of network devices or applications with particular packet configurations.

In contrast, other approaches such as Full Packet Capture encapsulate a larger series of packets, which means you would not have the granularity to manipulate single packets specifically. Packet Burst typically refers to sending a series of packets quickly in succession, rather than focusing on individual packet details, while Group Packet may involve batches of related packets but lacks the specificity of manipulating a single packet at a time. This distinction makes Single Packet the optimal method for those requiring detailed control over packet transmission.
