摘要： The number of response-waiting requests which are already sent to a server (4) but to which a response is not yet returned from the server (4) is limited. To limit this number, received requests are temporarily accumulated in a buffer if the number of response-waiting requests has reached a threshold and, until the number of response-waiting requests falls below the threshold, requests are not sent from the buffer. The execution status of the server (4) is monitored, and the threshold is increased when the response time from the server (4) to a request is within an allowable range, and the threshold is decreased when the response time exceeds the allowable range. In addition, TCP connections between a load control device (3) and clients (1-1, 1-n) are aggregated so that the number of simultaneous connections of TCP connections between the server (4) and the load control device (3) becomes equal to or smaller than the threshold of the number of response-waiting requests.
摘要翻译：已经发送到服务器（4）但尚未从服务器（4）返回的响应的响应等待请求的数量受到限制。为了限制该数量，如果响应等待请求的数量已达到阈值，则接收的请求被临时累积在缓冲器中，并且直到响应等待请求的数量低于阈值，则不从缓冲器发送请求。监视服务器（4）的执行状态，并且当从服务器（4）到请求的响应时间在允许范围内时阈值增加，并且当响应时间超过允许范围时阈值减小。此外，负载控制设备（3）和客户机（1-1,1-n）之间的TCP连接被聚合，使得服务器（4）和负载控制设备（3）之间的TCP连接的同时连接的数量变得等于或小于响应等待请求数的阈值。

摘要： A data selection apparatus which performs selection processes in parallel is provided. The data selection apparatus includes search units and a unit output control device. Each of the search units includes table search circuits and a data output control circuit which selects the highest priority output data. The unit output control device selects the highest priority output data from outputs of the search units. A table search circuit which succeeds in a search sends a search success signal to the data output control circuit. The search unit including the data output control circuit sends a unit search success signal to the unit output control device before performing a selection process for the highest priority data.

摘要： In order to make the client host capable of learning an accounting information or an authentication failure information, the accounting information or the authentication failure reason is notified from the routing device 2 to the client host 3, by adding an information regarding the accounting or an information regarding a reason for the authentication failure of the client host 3, to a packet of a protocol based on IGMP or MLD which is a multicast control packet between the client host 3 and the router device 2.
