SV-2 Systems Resource Flow Description

A System View (SV)-2 “Systems Resource Flow Description” specifies the System Resource Flows between Systems and may also list the protocol stacks used in connections. It’s used to give a precise specification of a connection between Systems. This may be an existing connection, or a specification for a connection that is to be made.

Guide: DoDAF Architecture Framework Version 2.02 – Page 207

The intended usage of the SV-2 includes:

  • Resource Flow specification

A SV-2 comprises Systems, their ports, and the Resource Flows between those ports. The architect may choose to create a diagram for each Resource Flow for all Systems or to show all the Resource Flows on one diagram if possible.

Each SV-2 model can show:

  • Which ports are connected?
  • The Systems that the ports belong to
  • The definition of the System Resource Flow in terms of the physical/logical connectivity and any protocols that are used in the connection

  • The DoDAF descriptions in this website are very generic and are mostly taken from the DoDAF Architecture Framework website. Make sure you visit the actual website for the most update information and a more thorough explanation of each viewpoint.
  • DoDAF Version 1.0, although outdated, has some good examples on how to construct AV’s, OV’s, and SV’s.
