    • Session Initiation Protocol (SIP), a protocol used in VoIP (Voice over IP) communications, enables a caller to send a SIP message to a callee with his/her UserID concealed from the callee, which in turn, prevents A SIP server from making an attempt to manage the caller. If the same IP Telephone address is used whenever the IP call is made, a third party may guess the IP address easily during conversation. The SIP message sent by the caller is converted and conversion tables are managed by the SIP server. The IP Telephone modifies its IP address for each IP call. Thus, the caller can make a call to the callee with his/her UserID concealed from the callee using the SIP server with a message conversion function and communications carriers having SIP servers installed to manage the callers using their conversion tables. It is difficult to any malicious third party to guess the IP Telephone address, because the IP Telephone address is modified for each call.
    • 会议发起协议(SIP)是VoIP(Voice over IP)通信中使用的一种协议,使主叫方能够从被叫方隐藏的用户ID向被叫者发送SIP消息,从而阻止SIP服务器进行 尝试管理来电者。 如果在进行IP呼叫时使用相同的IP电话地址,第三方可以在通话过程中轻松猜测IP地址。 调用者发送的SIP消息被转换,转换表由SIP服务器管理。 IP电话修改每个IP呼叫的IP地址。 因此,呼叫者可以使用具有消息转换功能的SIP服务器从被呼叫者隐藏的他/她的UserID呼叫被叫方,并且安装了SIP服务器的通信运营商使用其转换表来管理呼叫者。 任何恶意第三方很难猜测IP电话地址,因为每个呼叫都修改了IP电话地址。

    • 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.
    • 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。
