' Square are ports. I use them to represent the Message Retransmission Service
' So, when Publisher creates messages from the relevant library, it will then
' store in to it's own designated database, and will also attempt to broadcast
' to the consumer it's relevant information. 
' They can perform basic synhronization or utilzie the CDMC: Content Delivery Management Server
' to manage the message payload by leveraging the MRS library to do the synching
' MRS library will check the data loss by taking the specified data to be 
' compared and then perform retransmission if needed.
