SV-2: Systems Resource Flow Description

A SV-2 specifies the System Resource Flows between Systems and may also list the protocol stacks used in connections.

A SV-2 DoDAF-described Model is 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.

The intended usage of the SV-2 includes:

  • Resource Flow specification.

Detailed Description:

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.

Note that networks are represented as Systems. The architect may choose to show other Systems being components of the network, i.e., if they are part of the network infrastructure.

Any protocol referred to in a SV-2 diagram needs to be defined in the StdV-1 Standards Profile.
