3. Typical architectures
The following architectures have been defined according to the location of the control point in the network. However, these architectures can be combined, using several types of control point, to achieve a higher-performance solution.
For each architecture, we will detail the components and operating principles – pre- and post-connection – used to meet the three objectives defined above.
A control kinematics action is said to be pre-connection if this action is taken before access to the network has been granted. If network access has been granted, the action is said to be post-connection.
