摘要： PROBLEM TO BE SOLVED: To provide a connection management method for a communication terminal, a router apparatus, a communication terminal, and a connection management system whereby when the router apparatus receives a packet addressed to a communication terminal with which the router cannot communicate, the router apparatus can immediately return an arrival error message to a sender. SOLUTION: In an IP network, a communication terminal connected to a link informs the router apparatus about its own communication state, when the router apparatus receives a notice denoting that the communication terminal is in a communication disabled state, the router apparatus shifts nearby cache entries around the communication terminal to a communication disabled state, and thereafter when the router apparatus receives a packet addressed to the communication terminal, the router apparatus immediately transmits the arrival error message to a packet sender.

摘要： PROBLEM TO BE SOLVED: To provide a mobile communication method preventing packet loss caused by hand-over of a mobile communication apparatus. SOLUTION: A mobile communication apparatus comprises: a neighboring access router information search unit 105 for discriminating presence/non-presence of an access router device entered in a neighboring access router information storage table 106; and a tunnel control unit 111 for requesting the establishment of a tunnel to the access router device if the access router device entered in the neighboring access router information storage table 106 is present, or requesting the establishment of a tunnel to a home agent device when it is judged that the access router device is not present. Thus, packets are transferred via the home agent device even if an access router of a move destination is not corresponding to a high-speed mobile IP, thereby reducing the packet loss.

摘要： PROBLEM TO BE SOLVED: To provide a router apparatus and a communication method to transfer a packet with priority to an outside base station from the router apparatus which receives the packet first, when a plurality of router apparatuses in a local network are connected to the external base station. SOLUTION: The router apparatus is provided with a lower layer information acquiring portion 38 for acquiring connection information, which comes from a lower layer 34, as to whether the connection is made to the base station of the external network; and a routing deciding portion 40 (decides the transfer destination), which at the time a packet from a radio terminal apparatus directed to the terminal of the external network within the same local network is received, when connection to the base is made, transfers the received packet to the base station, and which when the connection is not made, by referring to a routing table, decides on the transfer destination. As a result, since when connection is made to the base station, the received packet is transferred to the base station, the packet can be transferred to the outside via the router apparatus intended by the terminal, and in addition, the load in the inside of the local network can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide a method for automatically and flexibly setting the priority of each of physical router devices in a virtual router device comprising a plurality of the physical router devices. SOLUTION: Physical router devices 21, 22 report router state information to a router priority calculation device 20 via a local network 11. According to the router state information reported, the router priority calculation device 20 calculates the priority of each physical router device and reports the priority to the physical router devices 21, 22 via the local network 11. According to the priority reported, the physical router devices 21, 22 decide one master router and a backup router other than it from a plurality of the physical router devices. Thus, by utilizing the priority obtained from the router state information on the physical router devices 21, 22, it is possible to automatically and flexibly constitute the virtual router device.

摘要： PROBLEM TO BE SOLVED: To enable automatic setting when a router is newly registered, to reduce setting load of the router registration which has been conventionally made manually by an operator, and to dispense with a monitor device. SOLUTION: The router 10 is equipped with a VRRP (Virtual Router Redundancy Protocol) which realizes a virtual router operating a plurality of routers virtually as a single router. Setting of virtual router information is automated when newly connecting a router to a network by comprising: a virtual router processor 15 which executes virtual router processing; a virtual MAC (Media Access Control) address acquisition part 16 which receives a virtual router information message, then extracts and acquires an originator's address from a MAC header of the message as the virtual MAC address; and a virtual router information processing part 14 which extracts the virtual router information, and performs necessary setting of operation as the virtual router. A load which is conventionally carried out by manual setting of the managing operator for composition of the virtual router system, is largely reduced. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To switch a default router of a terminal within a LAN to another router unit at high speed while suppressing a packet loss. SOLUTION: When it becomes impossible to provide a routing function of a default router 11 at present, multi-address distribution of a routing stop message is performed to all terminal devices 13 and other router units 12 within the LAN and when any other router unit 12 is capable of providing the routing function, multi-address distribution of a routing start message is performed to all the terminal devices 13 and the other router units 11 within the LAN. Thus, the terminal devices 13 within the LAN switches the default router in a predetermined timing on the basis of both the messages, thereby suppressing small a default router switching delay time and suppressing low the packet loss.

摘要： PROBLEM TO BE SOLVED: To swiftly perform switching of master backup in network connection apparatuses which are interconnected with each other by adopting a virtual redundancy configuration. SOLUTION: A first network connection apparatus that is in a standby state receives an advertisement message from a second network connection apparatus that is operating as a network connection apparatus, and uses a priority comparison part 203 to compare its own priority with the priority in the received advertisement message. When its own priority is higher, the first network connection apparatus uses a master countdown timer comparison part 212 to compare the remaining time of a master down timer 205 for determining whether the advertisement message is received in a prescribed time from the second network connection apparatus with the time as weighted in accordance with its own priority, and resets the timer for a shorter time. When the master down time expires, a message processing part 202 notifies the second network connection apparatus that the first network connection apparatus has been shifted to an active state.
