Abstract
During monitoring of a buffer configured so that expansion of an extent c of a buffer capacity takes place when the size of an unused region is reduced to a required expansion threshold value b, execution of a required calculation using an expansion threshold value b and buffer capacity extent c and c' (where c' is an initial value) for each point of time occurs. The reference values s1 and s2 corresponding to buffer capacities c and c' for each time point are determined and those reference values are used as the basis for screen display of expansion changes to the extent of the buffer capacity, thereby ensuring that a content of a display occurs corresponding to expansion for the extent of a buffer capacity. In addition, the use of the calculation formula for reference value s1 or s2 can be selected, while it is also possible to use a reference value (a fixed value ) which has been defined by the user.
