A planning tool has been developed in the 2010-2011 time frame based on a series
of Use Cases established by the SG Networks Task Force within the Open SG Users
Group. This organization is tasked by NIST with the requirements definition of
the Wireless Communications requirements for the Smart Grid. (http://osgug.ucaiug.org/default.aspx)
For each Use Case, every conceivable message has been catalogued, along with the
payload size in bytes, security requirements, source actor, target actor,
frequency of transmission, time of day when transmitted, and other parameters.
The end result is a database containing over 8000 records that can be queried in
analyzing a particular requirement or data need. In a very real sense, it is a
work in progress as new Use Cases are constantly being added to the database.
In the following screen, the Actor-Actor connections exist at the Application
Level (Level 7) in the Open Systems Interface (OSI) protocol stack. |
