Hi Sai Pavan,
In Newer versions of MATLAB one way to access and process Ethernet frames directly in MATLAB without using the TCP/IP protocol is by using low-level packet capture tools or libraries that MATLAB can interface with. One common approach is to use the “pcap” (packet capture) library along with MATLAB.
You can follow bellow steps to move forward with it.
  1. Install the ‘WinPcap’ or ‘Npcap’ libraries to ensure packet capture at low level. MATLAB has a support package for packet capture, which you can download and install.
  2. MATLAB provides functions to interface with ‘pcap’ files and capture live packets.
  3. Use the pcap functions to capture live packets.
You can also refer to this file exchange which some functions to work with *.pcap-files.
For detailed understanding of ‘pcapReader’, please refer to the following documentation:
Hope that helps!

Because TCP provides reliable transport with advanced features such as windowing and packet reordering, I do not recommend replacing it with home-brew packet transmission code. At most replace it with udp
