title: Finding the correct traversal path for a packet
body: <p><a href="https://i.stack.imgur.com/Qr0T4.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Qr0T4.jpg" alt="Common Link simulation" /></a></p>
  <p>Suppose a scenario similar to the above image where Node-A and Node-B are sending data to Node-D via Node-C. Node-A and Node-B each sent one data packet to Node-D.  Node-A sent one msg with msg-id = 1 which is received at Node-C with msg-id = 1 and Node-B sent one msg with msg-id = 3 which is received at node-C with msg-id = 3. Now, how I will get to know that the msg forwarded from Node-C with msg-id = 2 is the msg from Node-A or Node-B and msg forwarded from Node-C with msg-id = 4 is the msg from Node-A or Node-B? How I will follow the correct path while traversing the trace.json file of simulation?</p>
