    • Destination endpoints can use in-band signaling to adjust TCP parameters, to adjust entries in history and profile tables, to initialize a transition to an in-band communication mode, or to communicate short flows and/or alerts to a mobile device. A destination endpoint achieves in-band singling by embedding sequence number patterns in acknowledgement(ACK)messages, or by transmitting ACK messages(duplicates or otherwise)in accordance with an ACK sequence pattern. The sequence number or ACK sequence pattern can be pre-associated with any in-band communication message, such as a request to adjust TCP parameters, the reporting of a network or triggering condition, a request to adjust entries in a history or profile table, an indication to transition from a normal communication mode to an in-band communication mode, etc.
    • 目标端点可以使用带内信令来调整TCP参数,以调整历史和简档表中的条目,以初始化到带内通信模式的转换,或者向移动设备传送短流和/或警报。 目的地端点通过在确认(ACK)消息中嵌入序列号模式或通过根据ACK序列模式发送ACK消息(复制或其他方式)来实现带内转播。 序列号或ACK序列模式可以与任何带内通信消息预先关联,例如调整TCP参数的请求,网络的报告或触发条件,调整历史或简档表中的条目的请求, 从正常通信模式转换到带内通信模式等的指示。

    • Selectively ignoring congestion conditions may allow for more efficient transmission control protocol (TCP) communication in instance where reducing the transmission rate for a flow will not meaningfully mitigate congestion in the network or is otherwise undesirable. By way of example, congestion conditions may be ignored when a specific type of traffic flow is being communicated (e.g., short flows, high priority flows, etc.), when a traffic flow is being communicated at a low transmission rate, when a traffic flow is destined for certain type of network (e.g., a wireless network, etc.), or during any other situation in which reducing the transmission rate is undesirable. In some networks, a transmission rate is maintained until a certain number of duplicate ACKs are received (e.g., three duplicate ACKs, etc.) in order to ensure that congestion is indeed present before reducing quality of service (QoS).
    • 选择性地忽略拥塞状况可能允许更有效的传输控制协议(TCP)通信,例如,降低流的传输速率将不会有意义地减轻网络中的拥塞,或者是不希望的。 作为示例,当业务流以低传输速率传送时,当业务流被传送时(例如,短流,高优先级流等)可能忽略拥塞状况,当流量 流量注定到某些类型的网络(例如,无线网络等),或者在不希望降低传输速率的任何其它情况下。 在一些网络中,保持传输速率直到接收到一定数量的重复ACK(例如,三个重复ACK等),以便在降低服务质量(QoS)之前确保拥塞确实存在。

    • Transport control protocol (TCP) parameters can be dynamically selected to increase communication network performance. The TCP parameters may be selected before usage or at start-up such that a TCP connection is dynamically configured/re-configured prior to transporting the traffic flow over the network. The TCP connection parameters may be selected in accordance with a traffic characteristic, a network characteristic, a history of traffic activity, expected loads, desired throughput and latency or some other selection criteria. TCP parameters may also be selected after beginning to transport traffic flows over the network. More specifically, transportation of a traffic flow over the network may begin immediately using default TCP parameters, with the TCP parameters being updated or selected only upon the occurrence of a congestion or triggering condition. Further, multiple clients may share a set of persistent time-shared TCP connections.
    • 可以动态选择传输控制协议(TCP)参数来提高通信网络性能。 可以在使用之前或启动时选择TCP参数,使得在通过网络传输业务流之前动态地配置/重新配置TCP连接。 TCP连接参数可以根据业务特性,网络特性,业务活动历史,预期负载,期望吞吐量和等待时间或一些其他选择标准来选择。 开始传输网络上的业务流之后也可以选择TCP参数。 更具体地说,通过网络的业务流的传输可以使用默认的TCP参数立即开始,其中TCP参数仅在出现拥塞或触发条件时被更新或选择。 此外,多个客户端可以共享一组持久的时间共享TCP连接。

The method includes: acquiring data information in a data packet transmitted on a target TCP link or transmission information generated in a process of transmitting the data packet; determining, according to the data information or the transmission information, a target network type of a network on which the target TCP link is located; searching a pre-established configuration library for a target TCP configuration file corresponding to the target network type, where the configuration library includes a correspondence between a network type and a TCP configuration file, and each network type corresponds to one TCP configuration file; and configuring the target TCP link by using the searched target TCP configuration file. According to the method, the configured target TCP link is better adapted to a network on which the target TCP link is located; use of network bandwidth can be maximized; and TCP transmission efficiency can be improved.
