摘要： 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).
摘要翻译：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。

摘要： 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.
摘要翻译：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。

摘要： This application discloses a blockchain maintenance method. The method is used to add a target blockchain node group of a first tenant to a channel. In the method, a management node sends new channel configuration information of the channel to an execution node of a second tenant. The execution node of the second tenant generates incremental configuration information of the channel based on the new channel configuration information and old channel configuration information of the channel, and sends the incremental configuration information to a consensus organization. The incremental configuration information includes an identifier of the channel and configuration information of the target blockchain node group, but does not include configuration information of all blockchain node groups that have joined the channel. Each blockchain node group that has joined the channel obtains, from the consensus organization, a block including the incremental configuration information, and adds the block to a stored blockchain, to reach a consensus that the target blockchain node group joins the channel. The target blockchain node group is configured based on the incremental configuration information to join the channel.
