Title: Updating system for address table
Inventor: OTERU YOICHI
IPC: G06F13/00
Filed: 1988-10-03
Abstract: PURPOSE:To assure the transmission of a packet despite the shift of a communication terminal and at the same time to properly update an address table with no deterioration of the availability of a communication channel by varying the transmitting time of a shift informing packet and the address holding time. CONSTITUTION:In a packet communication system including the communication terminals 23 - 28 and a connection device 29, the device 29 owns an address table and the routing of a packet is performed based on the contents of the address table. In the case the terminal has a change like a shift, the shift informing packets are always sent into all communication networks after the change. Thus the address table is quickly and surely updated and the packet transmission is assured. When the addresses stored in the address table are updated, these addresses are not equally erased in a fixed time and the holding time of the addresses can be varied in accordance with the observed frequency. Therefore the address of a terminal having the higher communication frequency is held in the address table longer. Thus the response is improved to the difference of communication frequencies, etc., together with improvement of the availability of a communication channel. At the same time, the address table is properly updated.
