摘要： A management apparatus is communicable with a plurality of detection apparatuses for detecting a loss of a packet transmitted from a source apparatus to a destination apparatus. The plurality of detection apparatuses are disposed on a communication path of a connection between the source apparatus and the destination apparatus. The management apparatus includes a processor. The processor acquires, upon receiving a notice of the loss of a packet from a first detection apparatus, the lost packet from a second detection apparatus disposed on a communication path between the source apparatus and the first detection apparatus. The processor transmits the lost packet to a third detection apparatus disposed on a communication path between the first detection apparatus and the destination apparatus.

摘要： In a method and a device for notifying a server failure recovery which notify a failure recovery of a server or the like to a client, a server failure detector detects a client having tried but failed to access a server due to a failure, a server recovery detector detects a failure recovery, and a server recovery notifier gives a failure recovery notification to the client having failed to access. Also, the server failure recovery notification device is mounted on a router. The server failure detector detects the client having failed to access based on a destination unreachable message of an ICMP of the router 40, or detects the client having failed to access by determining the failure is being occurred in the server, in the absence of a reply IP packet to the IP packet addressed to the server from the client.

摘要： An incoming call notification apparatus which is capable of notifying an operator of a called terminal of an incoming call received when the terminal was not capable of answering an incoming call. When a terminal calls another terminal which is in use or in communication with still another terminal, an incoming call information storage apparatus stores incoming call information of the incoming call. When the called terminal becomes capable of accepting a call, a call setup message transmission apparatus reads out the stored incoming call information, produces a call setup message containing the incoming call information, and then transmits the call setup message to the called terminal. A disconnect apparatus executes incoming call abortion processing after completion of a calling (ALERT) sequence carried out in response to the call setup message during the incoming call processing.
