1. A method for controlling data flow in a store-and-forward communications node, the method comprising the steps of:

  • assigning priority value ratings for determining whether to admit a receive data message to a buffer memory of a communications node;

    detecting if the buffer memory is congested;

    defining a storage capacity range for each class of priority value ratings of the receive data messages;

    admitting the receive data message to the buffer memory if the arriving receive data message falls within the capacity range and if the buffer memory is not congested; and

    displacing a stored data message in the buffer memory with the arriving receive data message if the arriving receive data message has a first assigned rating value higher than a second assigned value rating of the stored data message and if the buffer memory is congested.
