A method of setting terminal state and assigning ID number for stack network concentrators, and a device executing the method are provided. A terminal state setting is executed when a concentrator detects that there is no electric signal, through one of it's I/O ports, coming from its adjacent counterpart. A device for implementing such execution includes a first power source generator, a first power source detector, a second power source generator and a second power source detector. Steps for implementing the ID number assignment includes: a) causing two I/O ports of each concentrator in an open state, b) sequentially assigning distinctive ID numbers respectively for the concentrator, and simultaneously causing two I/O ports of the one concentrator having been assigned ID number in connecting state, and c) reiteratively executing step b) until all concentrators have been assigned ID numbers respectively. A device for implementing the above steps includes a network agent, a plurality of pairs of switches and multiple transceivers in order to assign ID numbers respectively for concentrators in a network system with stackable concentrators.

The present invention is related to a method adapted to be used in hashing algorithm for reducing conflict probability which comprises the steps of receiving a first physical address of a frame; generating a hashing address corresponding to the first physical address; comparing a second physical address corresponding to the hashing address with the first physical address to determine if the first and the second physical addresses match with each other; completing a packet calling process when the first and the second physical addresses match with each other, but going back to the comparing process when the first and the second physical addresses do not match with each other, to determine whether there is another second physical address corresponding to the hashing address and matching with the first physical address; and ending the packet calling process when a number of times that the comparing process is proceeded is greater than a reference value. By this method, a specific conflict probability is obtained, and according to the results, the conflict probability and the broadcasting probability are reduced and the source of the network is saved.
