Solution

1. 1st Part (Conditions):

• Data transmission may be counter clockwise
  
• Nodes should not fail during the process.
  

2. 2nd Part (Protocol):

• Sensing idle connection before data transmission
  
• Re-send data if packet data is corrupted or lost
  

3. 3rd Part (Data transmission):

• Data is transmitted by computer A and received by computer H
  
• Computer H receives it and then re-sends it to next computer which is computer H
  
• Computer H also receives it and finds it to be not related to computer H. Therefore, it passes the data to next computer which is F
  
• Computer F receives the data and processes it
