Ethernet Header Extraction Tool with MATLAB Implementation

This document describes an Ethernet header extraction tool developed using MATLAB. The tool captures network packets and records critical information including timestamp, packet length, and data field content. In the field of network security, this tool proves particularly valuable as it enables analysts to gain deep insights into network traffic patterns, facilitating the detection of network attacks and other security threats. Additionally, network administrators can utilize this tool for monitoring network traffic to better understand usage patterns and identify performance bottlenecks. The MATLAB implementation likely utilizes key functions such as pcap file reading routines or real-time packet capture interfaces to extract Ethernet frame headers. The packet processing algorithm probably follows standard Ethernet frame structure parsing, where the tool dissects the 14-byte header containing destination/source MAC addresses and EtherType fields, followed by payload extraction. The timestamp recording feature may employ MATLAB's high-precision timing functions to capture packet arrival times with millisecond accuracy. Overall, this MATLAB-based tool provides valuable information for network security professionals and administrators, assisting them in enhanced network protection and management through detailed packet-level analysis. The code architecture likely incorporates modular design for easy extension to handle various network protocols and export formats for further analysis.
