Abstract: Provided is a communication apparatus by which a user can simply set a transmission quality in a network and QoS control effectively functions. QoS type receiving sections (11, 21, 31, 41) are arranged in communication apparatuses (10, 20, 30, 40) on a network, and a user is permitted to specify a QoS type to be requested to the communication apparatuses (10, 20, 30, 40), by operating the QoS type receiving sections (11, 21, 31, 41). When the communication apparatuses (10, 20, 30, 40) perform communication, the network is controlled to ensure the QoS corresponding to the QoS type received by the QoS type receiving sections (11, 21, 31, 41).

Abstract: A method for asynchronous communication through an IEEE 1394 bus in a wireless environment (wireless bus) by allowing a hub station to integratedly manage information unique to wireless communication. Each of wireless terminals sends a request for transmission of an asynchronous packet along with the wireless terminal identifier of the destination in a status packet for reporting the receive status of another wireless terminal to the hub station. The hub station performs, according to the information, allocation of transaction label, selection of optimum modulation method and coding rate, decision of relay, decision of polling priority, and reports the results to the wireless terminal through a polling packet representing the send privilege of an asynchronous packet. The wireless terminal that obtains the send privilege and the wireless terminal of the destination send/receive data according to the information, thereby transmitting an asynchronous packet in requisite minimum procedures.
