Abstract
The invention provides a method of measuring the load of a communication system, and more particularly of a multiplex switching network for asynchronous cells or packets. Each cell transmitted on the multiplex has a registered value which is divided by a predetermined number (N). The value forms the first operand (E2) of a subtraction and the result of the division forms the second operand (E1). A predetermined value is added to the result of the subtraction when the heading of the transmitted cell contains a particular identifier. A zero value is added in the contrary case. The result of the subtraction followed by the addition constitutes the new value which is to be recorded, which likewise represents the measurement of the load. The identifier identifies, for example, an occupied cell or a cell belonging to a given virtual circuit. A circuit for implementing the method is likewise described.
