ABSTRACT:
A D-bit in an X.25 data packet access protocol flags whether an acknowledgment of packet communication can be local or must be end-to-end. The disclosed method with programmed processing handles the D-bit option by a two-sided memory table that couples the X.25 access protocol and the internal protocol of a packet switching network. The table, called rack.sub.-- perm (for Receive ACKnowledgment PERMission) is set with one entry per data packet sequence number. The rack.sub.-- perm entries are modified by the internal protocol in response to an acknowledgment packet received from the switching network. Checks are made of rack.sub.-- perm by the internal protocol using indices of the access protocol to determine the number of acknowledgment packets permitted to be sent to an originating data terminal equipment.
