Step 3: After receiving the request from the Car Dealership the Dealership Server records and registers the information to a Database. At this point the Car Dealership 1 essentially becomes a Peer (Server) to the other Dealerships since the Dealership Server will let any other Client or Car Dealership contacting it that you have files available.
Step 4: Car Dealership 2 contacts the Dealership Server looking for a certain file
Step 5: Dealership Server searches it’s Database looking for a Car Dealerships that have that VIN persistent on their machine and as Peer/VIN pair is returned to the Server
Step 6: Dealership Server sends which Car Dealerships have the file requested
Step 7: Car Dealership 1 receives the Car Dealership which has the files from the Dealership server, selects one Car Dealership, in this case Car Dealership 2 to obtain the VIN
Step 8: Car Dealership 2 verifies that it has the file and sends it to Car Dealership 1
Step 9: Car Dealership 1 registers to the Dealership Server that it has the file it requested and Step 3 initiates
Step 10: If no Car Dealership within the network has the file the Dealership Server contacts the VIN server to get the file
