Title: Prioritized data packet switching system
Inventor: KUANKUI JIYANNPOORU
IPC: H04L12/56
Filed: 1988-07-14
Abstract: PURPOSE: To make a packet transmitting time lower than a preliminarily set limit value by assigning two priority orders to packets, and allowing each queuing file to access only to a packet with a higher priority order between the input and output of two zones. CONSTITUTION: The output of an input circuit CE is connected with the other input of an input rotary matrix MRE for operating parallel diagonal conversion. Each label (i) accompanied by a rank (e) of an input port carrying the label (i) is stored in a label conversion memory MC. The memory MC impresses a bit signal (p) which is 1 when a packet is not a high priority order, and which is 0 when the packet is the high priority order to a routing circuit ACE. A logic circuit engaged with each queuing file separately processes a normal packet and the priority packet as necessary. Thus, any danger that a priority memory may be overwritten in a memory MP can be reduced.
