    • A method of reducing the bandwidth usage of a network comprises intercepting traffic between a TCP server and a TCP client using TCP protocols that use client acknowledgements; identifying client acknowledgements from the TCP protocols; identifying the sequence number of a last received client acknowledgements from the intercepted traffic; identifying the sequence number of a last sent client acknowledgement from the intercepted traffic; calculating an unacknowledged byte value based on the difference between the last received client acknowledgement sequence number and the last sent client acknowledgement sequence number; comparing the calculated unacknowledged byte value with a predetermined threshold value, to determine whether the calculated unacknowledged byte value is at least as great as the predetermined threshold value; and transmitting the identified client acknowledgements into the network when the compared unacknowledged byte value is at least as great as the predetermined threshold value.
    • 降低网络带宽利用率的方法包括使用使用客户端确认的TCP协议拦截TCP服务器和TCP客户端之间的流量; 从TCP协议识别客户机确认; 从截获的流量中识别最后接收到的客户端确认的序列号; 识别来自截获的流量的最后发送的客户端确认的序列号; 基于最后接收到的客户端确认序列号与最后发送的客户端确认序列号之间的差来计算未确认的字节值; 将所计算的未确认字节值与预定阈值进行比较,以确定所计算的未确认字节值是否至少与预定阈值一样大; 以及当所比较的未确认字节值至少与所述预定阈值一样大时,将所识别的客户端确认发送到所述网络。

    • A system transports a plurality of UDP datagrams from a sending application to a receiving application by creating a TCP tunnel between a TCP sending-end and a TCP receiving-end, encapsulating the datagrams in TCP packets at the TCP transmitting-end, transmitting the TCP packets via the TCP tunnel to the TCP receiving-end over a network using a TCP/IP protocol, and extracting the datagrams from the TCP packet and forwarding the extracted datagrams to the receiving application. The TCP tunnel may provide the same delay and responsiveness as UDP protocol. The TCP receiving-end may detect when a packet is missing and request retransmission when a packet is missing, so that the TCP sending-end retransmits the missing packets. The transmitting of TCP packets to the TCP receiving-end continues when the receiving-end detects a missing packet, so that there is no lag in the forwarding of the extracted datagrams. Retransmitted packets may be discarded.
    • 系统通过在TCP发送端和TCP接收端之间建立TCP隧道将多个UDP数据报从发送应用传输到接收应用,在TCP发送端将数据报封装在TCP数据包中,发送TCP 通过TCP隧道通过TCP / IP协议通过网络将数据包发送到TCP接收端,并从TCP数据包中提取数据报,并将提取的数据报转发到接收应用程序。 TCP隧道可以提供与UDP协议相同的延迟和响应。 TCP接收端可以检测到数据包何时丢失,并且当数据包丢失时请求重传,从而TCP发送端重新发送丢失的数据包。 当接收端检测到丢失的数据包时,TCP数据包向TCP接收端的发送继续进行,从而在提取的数据报的转发中没有滞后。 重发数据包可能被丢弃。
