MLSN Protocol User Session Diagram

MLSN Protocol User Session Diagram



A Simple User Session



Scenario: User wants to know the status of a property listing in the downtown Orlando zip code, 32801, located in the United States.

A user starts a session on a client desktop. He enters the following MLS Number URL at the prompt:



user>mlsn 1.1.1@32801.840/status



The mlsn client application sends the MLSN URL via port 32801 over tcp through the internet to an MLSN Messaging Server which accepts the text string via port 32801.



The MLSN Server routes the URL text string to an application server which parses and creates a query for the database which returns a result.



The result is sent from the application server back to the MLSN Messaging Server which sends the result via port 32801 over tcp back through the Internet cloud.



Finally, the client desktop receives the result via port 32801 and displays the results to the user:



user>active
