Abstract
A node apparatus is provided for transmitting an ICMP data frame to a transmission source in response to an IP data frame received from the transmission source when detecting failure regarding the IP data frame. The node apparatus includes an information database storing information about necessity of generating the ICMP data frame for each attribute of the ICMP data frame corresponding to a type of the failure, an information management unit determining the necessity of generating the ICMP data frame by referring to the information database when the node apparatus detects the failure, and a processing unit generating the ICMP data frame if the information management unit determines that generation of the ICMP data frame is necessary, wherein the node apparatus transmits the ICMP data frame to the transmission source if the processing unit generates the ICMP data frame.
