摘要： A first issue is to provide a packet transfer device for identifying a connection such as a TCP connection linked to a bandwidth control means, and provide a proxy acknowledgment for each identified connection such as TCP. A second issue is to provide a packet transfer device for providing a proxy acknowledgment for a connection such as TCP, and capable of improving throughput such as for TCP just by being installed at a network edge section connected to the communication terminal. As a means to resolve the first issue, a packet transfer device is provided that contains a means for identifying flows such as TCP flows for deciding if the proxy acknowledgment means requires proxy acknowledgment or not, based on the bandwidth conformance flow reported from the bandwidth control means. As a means to resolve the second issue, a packet transfer device is provided that contains a means for converting stored packets to a protocol that does make a proxy acknowledgment, and a means for transmitting the converted packets to a packet transfer device installed on the network edge oriented towards the oncoming packets.
摘要翻译：第一个问题是提供用于识别诸如连接到带宽控制装置的TCP连接的连接的分组传送装置，并且为每个所识别的连接例如TCP提供代理确认。第二个问题是提供一种用于为诸如TCP之类的连接提供代理确认的分组传送装置，并且能够通过安装在连接到通信终端的网络边缘部分来提高诸如TCP之类的吞吐量。作为解决第一个问题的手段，提供了一种分组传送装置，其包含用于识别诸如TCP流之类的流的装置，用于基于从带宽控制报告的带宽一致性流来决定代理确认装置是否需要代理确认手段。作为解决第二个问题的手段，提供了一种分组传送装置，其包含用于将存储的分组转换为执行代理确认的协议的装置，以及用于将转换的分组发送到安装在网络上的分组传送装置的装置边缘朝向即将到来的数据包。

摘要： Unique addresses are provided to identify and communicate with each of a plurality of servers and a client connected on a network. A group address which differs from the unique address is assigned to any of the plurality of servers. The client specifies that group address when receiving service from the server. The traffic status of the communication path between server and client is monitored and if factors such as communication speed and response time have exceeded a preset threshold, the group address is dynamically passed to another server. Thereby a communications system is able to dynamically switch servers, the source for generating traffic, on the network without rerouting of paths on which traffic is concentrated and requiring no change settings or addition of control functions by the client and further able to effectively use portions of the network having low usage rates.

摘要： In order to realize server switching to a backup server from a working server without changing any setting on a client computer, a network system is provided having a network supervising means for supervising operations of a plurality of server computers connected to the network, a server switching means for realizing server switching in which the backup server computer alternatively executes the server function of the working server computer by virtually setting the address of the working server computer connected to the network as the address of the backup server computer. A packet converting means is provided for converting the packet transmitted and received between the working server computer and the client computer into the packet transmitted and received between the backup server computer and the client computer.
