摘要： A data transfer system allowing high-quality transfer of streaming data through a network having a relatively large delay variation in data delivery is disclosed. When transferring streaming data in packets from a server computer to a client computer through a repeater provided in the network, the repeater buffers a streaming packet for a set time period before forwarding it to the client computer. The set time period is determined so that a receiving time interval of packets at the client computer is substantially equal to a sending time interval of packets at the server computer.
摘要翻译：公开了一种数据传输系统，其允许通过具有相对大的数据传送延迟变化的网络高质量地传输流数据。当通过网络中提供的转发器将数据包从服务器计算机传输到客户端计算机时，转发器将流分组缓冲一段时间，然后将其转发到客户端计算机。确定设定的时间周期，使得客户端计算机的分组的接收时间间隔基本上等于在服务器计算机处的分组的发送时间间隔。

摘要： A task is to automatically carry out directional control of an antenna in parallel with routing in a radio network.In the event that a radio transmission apparatus 100, which is a node configuring the radio network, received a routing packet 200 from the node over the radio network, it acquires and records a received direction of the routing packet 200, an identifier of a transmission source node, metric information indicating a route cost, and an identifier of a route destination node, and in the event that the route destination node is not its own node, the radio transmission apparatus 100 takes control so as to match a direction of an antenna system 101 to the received direction of the node having minimum metric information out of the recorded metric information.

摘要： The above base-station cell design method is for sequentially adding base stations, and a technique of which throughput is few is employed for a radio-wave propagation characteristic evaluation to be made in this addition, and a technique of which the throughput is much, but which is of high-precision, more specifically, a technique such as the ray tracing is applied for the radio-wave propagation characteristic evaluation to be made after addition. The result of the high-precision radio-wave propagation characteristic evaluation to be made after this addition is put to practical use for estimating an interference quantity in selecting the arrangement location of the base station to be added newly. This allows the quantity of the radio wave analytic processing, which accounts for a large majority of the base-station cell design processing, to be reduced, thus enabling a fast base-station cell design.

摘要： A system is connected to an access point via a network, receives packet transmission information held by the access point, and extracts an address having a transfer destination which is radio interface from the packet transmission information. It is assumed that the terminal of the extracted address exists under the access point holing the packet transmission information. Thus, it is possible to realize connection relationship between a terminal and an access point at low cost and not depending on the vendor.
