(EN) The invention provides a fault notification method and electronic equipment. In the method, a first equipment sends a first TCP message carrying a first TCP option to a second equipment through a second sub-channel under the same MPTCP session, and the second equipment can determine a fault of the first sub-channel according to the first TCP option, so that an effective means for solving the fault can be adopted, for example, the fault can be effectively solved. According to the embodiment of the invention, the data of the first sub-channel can be switched to other non-fault sub-channels, or a new sub-channel is established to shunt the data of the first sub-channel, so that the transmission efficiency can be improved, and the transmission performance can be improved.
(ZH) 本申请提供了一种通知故障的方法和电子设备。该方法中，第一设备通过同一MPTCP会话下的第二子通道向第二设备发送携带第一TCP选项的第一TCP报文，第二设备能够根据第一TCP选项确定第一子通道故障，从而可以采取有效的解决故障的手段，例如，可以将第一子通道的数据切换到其他的非故障的子通道上，或者建立新的子通道来分流第一子通道的数据，这样，能够提高传输的效率，有助于提高传输性能。
