Abstract :
The contol scheme described has been designed so that it is automatic in two senses. The called party number identifying the resource in overload is automatically identified. The level of call restriction performed at nodes remote from the resource is updated dynamically in such a way that the ineffective calling rate at the resource is kept within an acceptable limit whilst the occupancy of the resource is kept as high as possible. The author gives a detailed description of the automatic call restriction scheme including possible enhancements and methods of implementation, defines two measures of performance for such control schemes, and summarises the performance for a simple network configuration
