Abstract

PURPOSE:To avoid a failure to effect on another line, by detecting the production of failure by receiving no response to transmission information after the production of failure and changing the path table corresponding from the transmitted address. CONSTITUTION:In a relay station making packet exchange of network having a plurality of paths to one terminal station, if failure production is detected, the failed line is read in. It is judged that the failure is for input/output circuit. If failure for the input/output circuit, the failed line is detached from the common bus. If the said failure is not a cause, the information transmission terminal (MC) is read in, the minimum path of path table corresponding to MC is canceled and the spare path is changed to the shortest path. Thus, the effect of failure can be minimized independently of the network constitution.
