摘要： The present invention can prevent a fuzzy image, which is caused due to insufficient bandwidth when the bandwidth necessary for transmitting a content cannot be secured, to be displayed on a display device. When a relay apparatus (100) receives, from a DNS server, a DNS response packet regarding a domain name of a server which transmits a content, a condition judging section (210) in the relay apparatus (100) judges whether a required bandwidth for the content corresponding to the domain name can be secured in a communication path connecting to another relay apparatus (100). If the condition judging section (210) judges that the required bandwidth cannot be secured, a DNS modifying section (250) in the relay apparatus (100) rewrites a reply IP address included in the DNS response packet to an IP address of the relay apparatus (100).

摘要： There is provided a communication apparatus which, in an ad-hoc network, when receiving control packets from a plurality of terminals, can determine whether or not there is a collision among the control packets, and, based on the determination, can be prevented from continuing to be out of the network due to a collision among the control packets transmitted from the plurality of terminals. In the communication terminal, a communication section receives a control packet which periodically comes up on a communication path. When the communication apparatus receives a plurality of control packets which are defective in at least payload portions thereof within a predetermined time period, if a control section determines that source addresses included in header portions of the control packets which are defective in the payload portions thereof include a source address which is not identical to the other source addresses, the control section determines that the control packets are transmitted from a plurality of terminals and collide with each other.

摘要： A source apparatus writes, in a route request packet, the number of routes requested by the source apparatus. When a relay apparatus receives a route request packet for the first time, the relay apparatus determines a waiting time period, based on a route evaluation value that indicates a state of a route through which the route request packet has passed, and starts a timer. The relay apparatus selects route request packets having as high route evaluation values as possible, among route request packets that have been received until the timer expires, the number of route request packets to be selected being equal to the number of routes requested by the source apparatus, and then broadcasts the selected route request packets.
