Definitions
- (1) are required. Furthermore, the advantages of the already existing flow control mechanisms in (2) are used. In one exemplary embodiment, this is, for example, the avoidance of reactive loads by reducing the load at the sources.
- the algorithm of the flow control for overload protection for (2) itself also belongs to the invention.
- it consists of one part, where at the beginning of an overload period m a large regulation step is regulated down to the estimated load that can be managed by (2) and a second part, where remote regulation is performed based on the updated overload indication. This fine adjustment is also used when the output parameters are reset at the end of the overload situation.
- the two-stage control algorithm has the The advantage that a sudden overload can be reacted to, but at the same time that the current load range can be adjusted by means of fine adjustment and vibrations in the system throughput can be avoided.
- a special feature of the invention is the separation of overload notification and flow control.
- the two-stage control algorithm is very advantageous in the exemplary embodiment.
- Message transfer protocol is SSCOP, which
- Another application with the same procedure as in the first exemplary embodiment can be operated with the message channel (3) as UNI, with application PNNI and otherwise as above.
