A packet is the basic unit of network communication and contains information exchanged between a sender and a receiver. Imagine that the network is like a highway, and the data packets are the trucks carrying the data. Each packet has a specific address (IP address) that tells it where it should go.

Why do you need to parse the packet? Network troubleshooting: By analyzing data packets, you can quickly locate the causes of network failures, such as packet loss, excessive delay, protocol errors, etc.

• Network security analysis: Discover security threats such as network attacks and virus intrusions.
• Performance optimization: analyze network traffi Phone Number optimize network configuration, and improve network performance.
• Protocol Analysis: Gain an in-depth understanding of how network protocols work.
  

A typical data packet contains the following parts:

• Frame header: Contains source MAC address, destination MAC address, type and other information.
• IP header: Contains source IP address, destination IP address, protocol type, TTL and other information.
• Transport layer header: Contains port number, sequence number, confirmation number and other information (TCP) or checksum (UDP).
• data:
