摘要： A communication apparatus of the present invention is used in the network where data communication is performed, and includes: a priority data information holding section for holding, in advance, QoS setting information corresponding to domain names, which QoS setting information is necessary to perform QoS setting for data communicated in the network; a control packet snooping section for snooping on a DNS packet received from a DNS server, and obtaining a domain name contained in the DNS packet; and a priority control setting section for, when QoS setting information corresponding to the obtained domain name is contained in the QoS setting information held in the priority data information holding section, performing, based on the QoS setting information, QoS setting for data communication performed by a communication apparatus which is the transmission source of the DNS packet. Thus, the communication apparatus of the present invention can reduce processing load for QoS setting for an AV flow which is used in real time communication, and can detect even an AV flow for which an unpublished protocol or the like is used.

摘要： A communication apparatus used in a network where data communication is performed includes a priority data information holding section that holds, in advance, QoS setting information corresponding to domain names, where the QoS setting information is necessary to perform QoS settings for data communicated in the network. A control packet snooping section snoops on a DNS packet received from a DNS server, and obtains a domain name contained in the DNS packet. A priority control setting section, when QoS setting information corresponding to the obtained domain name is contained in the QoS setting information held in the priority data information holding section, performs, based on the QoS setting information, a QoS setting for data communication performed by a communication apparatus which is the transmission source of the DNS packet.
