System Views (SV) [Physical, Specification or Solution Views]
SV-2c System Connectivity Clusters v1.2
A System Connectivity Clusters (SV-2c) Product defines how individual connections between systems are grouped into logical connections between parent resources.
Background:
An SV-2c Product serves to define the connectivity requirements between resources which host one or more systems. Typically the hosting resource will be a Physical Asset, though it could be an Organisational Resource.
Usage:
- Interface specification
- Bandwidth & Capacity Analysis
Data objects:
The data in an SV-2c can include:
- Physical Asset
- Organisational Resource (Post Type or Organisation Type)
- System
- System Port
- System Port Connection
Relationships Between Key Data Objects (Simplified from M3)
Representation:
- UML Composite Structure Diagram
- Topological (Connected Shapes)
Detailed Product Description:
A System Connectivity Clusters (SV-2c) Product defines how individual connections between system ports are grouped into logical connections between parent resources. When one or more systems are hosted by a resource, and those systems communicate with other systems hosted by other resources, it is sometimes useful to present the resources, with their systems and connections in order to support data capacity and bandwidth analysis.
An SV-2c Product serves to define the connectivity requirements between Resources, and may be used for estimating requirements for physical routing and bandwidth as well as defining the physical architecture within a System or System of Systems. An SV-2c View is particularly useful when planning physical connections and routings between Physical Assets.
The SV-2c View is intended to aid analysis of the connectivity between systems which are hosted separately. In particular it is a useful way of highlighting redundancy issues, showing when too many or too few connections are used. This could indicate opportunities for cost savings from using a common network, or there may be a need for redundancy to increase reliability.
An SV-2c View consists of a diagram for each inter-Asset connection. Each diagram shall show:
- The hosting resources, and their systems (this should be a simple 2-level decomposition)
- The system-to-system connections which run between
- Which ports are used in the system-to-system connections.
Example SV-2c
The numbering and identification of the systems and system ports is at the discretion of the architect defining SV-2c.
