Purpose

From The MODAF System Viewpoint (SV) p13:

An SV-2b specifies the communication links between systems and may also list the protocol stacks used in connections.

Note: Protocol Stack was deleted at 1.2.004 so not sure this description is correct.

Background

From The MODAF System Viewpoint (SV) p13:

An SV-2b Product is used to give a precise specification of a connection between systems.

Description

From The MODAF System Viewpoint (SV) p14:

Each diagram shall show:

  • Which ports are connected.
  • The systems to which the ports belong.
  • The definition of the connection in terms of the physical connectivity and any protocols that are used in that connection.

The SV-2b view is closely related to the SV-2a view that specifies the available protocols on each port. Any connection specified in an SV-2b view shall conform to the protocols specified on the corresponding port definitions in the SV-2a view.

Comments

Care is needed - the SV-2b only allows resource interactions between systems to be described and characterised. Although at MODAF 1.2.004 any Resource can have a Resource Port this relationship cannot be shown in a SV-2b. You cannot therefore use it to describe interactions between Human Resource (Organisation, Job, Role).

Description isn’t consistent with simplified metamodel - Software, Software Port, Resource] Interaction and Implemented Protocol missing from data objects
