Abstract: According to an embodiment, an information processing apparatus has a first interface connectable to an external server, a second interface connectable to a display, and a processor. The processor is configured to receive order data for dinning orders via the first and second interface and cause the display to display order data in a first area or a second area depending on whether the order data is first-type order data or second-type order data. The first and second areas are separate areas. The first-type order data is for dining orders of a first type, such as delivery orders, and the second-type order data is for dining orders of a second type, such as in-store dining orders.

Abstract: A packet relay device comprises a distribution processing unit classifying traffics into groups and users based on header information of packets received; a calculation unit calculating available frame rate of each user from peak frame rate, minimum frame rate, and weight information set for each user; a scheduling control unit updating a transmission schedule point-in-time calculated based on the available frame rate of each user, and judging which packet should be transmitted in accordance with the transmission schedule point-in-time updated; and a shaping unit updating a transmission schedule point-in-time calculated based on the peak frame rate of each user, and performing a shaping of packets at the peak frame rate on each user basis in accordance with the transmission schedule point-in-time updated; and a priority-control processing unit performing a strict priority control over transmission of packets of each group in correspondence with degree of priority of each group.

Abstract: A bandwidth calculation section calculates a usable bandwidth from a communication amount of each user or a session connection time stored in a statistic management memory and minimum bandwidth information and maximum bandwidth information recorded in a bandwidth setting memory. The bandwidth calculation section allocates a large usable bandwidth to a user with a small communication amount or a short session connection time. A transmission control section performs transmission scheduling of packet information stored in a packet buffer based on a transmission scheduled time calculated from the usable bandwidth stored in a transmission scheduled time memory.

Abstract: There are provided a distribution unit for classifying traffics into group/user/class units, a transmission point-in-time processing unit for calculating available frame rate from peak-frame-rate/minimum-frame-rate/weight set for each user, and managing a transmission schedule point-in-time, a scheduling control unit for controlling a scheduling in accordance with the transmission schedule point-in-time, a user/group/line's each peak-frame-rate control unit for performing a shaping of the traffics at each peak frame rate of the user/group/line, and a priority-control processing unit for carrying out an inter-groups priority control.

Abstract: A traffic shaping apparatus calculates a minimum transmission interval, an allowed transmission frame rate of a user frame, and a reference transmission interval for each user according to a minimum transmission frame rate and a peak transmission frame rate specified for each user. The traffic shaping apparatus also calculates a first estimated transmission time according to the reference transmission interval, and a second estimated transmission time according to the minimum transmission interval for each user. The traffic shaping apparatus determines the user having the earliest first estimated transmission time, and determines according to the second estimated transmission time of the user whether a user frame is to be transmitted.

Abstract: In a wireless LAN system, each wireless terminal device determines whether or not the wireless terminal device has entered into a wireless LAN domain established by a base station, and if it has entered, transmits an entry terminal identification information update control frame including identification information of its own device to the base station at a predetermined time interval. The base station receives the entry terminal identification information update control frame from the wireless terminal device, stores in a storage the identification information of the wireless terminal device entered into the wireless LAN domain established by its own base station, and when it receives an information frame from a wired transmission line connected to its own base station, relay-transmits only the information frame to the wireless terminal device having the identification information thereof stored in the storage by referring the information stored in the storage.
