Abstract
The invention relates to a buffer management method for sharing the storage capacity F of a buffer between its users, such as queues, communication links or equivalent, which store packets in the buffer, in which method the total number of packets stored in the buffer is calculated and, based on this, the buffer capacity to be granted to the users is controlled. According to the invention, a modified total number of packets T* stored in the buffer is determined from equation (1), where N=total number of users; a(i)=minimum buffer capacity (a(i>0)) allocated for user i; and c(i)=actual buffer capacity occupied by user i at the reference instant. Further, the storage of additional packets by user i is inhibited if the total T*>F and c(i)>a(i).
