Abstract:
PURPOSE: A method for controlling a queue by a weight value is provided to prevent that a cell having a priority is delayed or stopped by a cell having a low priority. CONSTITUTION: A plurality of queues are set in one output port. A plurality of queues loads a predetermined weight value according to a priority of each cell. A queue having the highest weight value among the loaded weight value is selected and the cell is transmitted. The weight value of the queue which transmits the cell is subtracted. A value for adding weight values of a corresponding cell of the other queues is subtracted from all weight values of the corresponding queue.

Abstract:
PURPOSE: A method for managing an endpoint address for packet tunneling in a data communication system is provided to manage a tunnel endpoint address for packet tunneling by using a linked list table including at least one linked list entry, thereby reducing a processing time of the tunnel endpoint address and improving memory access performance. CONSTITUTION: When a registration command for a tunnel endpoint address is inputted(100), a processor re-disposes the tunnel endpoint address, and inserts a mode bit showing a kind of a packet corresponding to the tunnel endpoint address(110). The processor extracts lower 19 bits of the tunnel endpoint address as a hash key(120), and retrieves a hash table by using the extracted hash key(130). The processor decides whether a corresponding hash entry is available(140). If not, the processor registers a new linked list entry in a foremost position of a corresponding hash chain(150). Indexes are stored in a field of the new linked list entry(170).
Abstract:
A process automation system is provided to enhance system management efficiency by directly exchanging a mark-up language file between a process automation server and a manufacturing device through a mark-up language web transmission. A process automation system includes a manufacturing device(210) and a manufacturing execution server(200). The manufacturing device converts status information, which is generated in a manufacturing process, to a mark-up language file and transmits the converted result to an upper level through a web communication(220) through an HTTP(Hypertext Transfer Protocol) web scheme. The manufacturing execution server stores a mark-up language file received from the manufacturing device, converts the stored mark-up language file to a text file, and supplies the converted text file to a manager.
