摘要：A communication device connected to a packet network, which is provided witha storage portion having communication-tracing-information storing areas respectivelyassigned to logical channels and a communication processing portion for identifying alogical channel by a network header of transmission or reception data obtained from thepacket network when the transmission or reception data is generated, and for writingcommunication-tracing-information corresponding to the generated transmission orreception data to a communication-tracing-information storing area assigned to theidentified logical channel. Thus, communication-tracing-information is stored in thecommunication-tracing- information storing areas respectively corresponding to logicalchannels. Thereby, the stored communication-tracing-information corresponding to alogical channel is not written over that corresponding to another logical channel.Therefore, if a communication fault occurs correspondingly to a logical channel andthereafter a normal communication processing is effected correspondingly to anotherlogical channel, communication- tracing-information corresponding to the logical channel,in which the communication fault has occurred, can be retained. Consequently,communication-tracing-information corresponding to a logical channel, in which a

communication fault occurs, can surely be retained and easily be fetched withoutincreasing the cost. Moreover, an analysis of the communication fault can efficiently beperformed.
