摘要： A method and an apparatus for changing an overhead and preventing subnets from switching simultaneously, a network element, and a network are disclosed. The method for changing an overhead includes: detecting that a fault occurs, and the fault triggering an embedded optical transport subnet and an outer subnet thereof to perform protection switching; changing a value of an overhead which will trigger protection switching of the outer subnet in a signal to be transmitted to a downstream network element to a value which will not trigger protection switching of the outer subnet; and cancelling the change after the change lasts for a period of time, wherein the period of time is less than or equal to a set change lasting time. A network element of an embedded subnet in multiple nested subnets performs said method for changing an overhead, and meanwhile sets a protection switching delay trigger time of a network element performing protection switching in the outer subnet to be less than a longest service transient interruption time possibly caused during the protection switching of the embedded subnet, so as to prevent subnets from switching simultaneously and reduce the protection switching delay caused by a fault outside the embedded subnet and in the outer subnet. The present application further provides a corresponding apparatus, network element, and network.

摘要： The present invention relates to a method, device and system for fast protection of an optical network system, in particular for a Passive Optical Network (PON), such as a Gigabit-capable Passive Optical Network (GPON). In the method, communication failure between a first optical network device and a first optical line termination device is detected. Switching of functionality from the first optical line termination device to a second optical line termination device is initiated, and a control message is sent from the second optical line termination device to the first optical network device such that the first optical network device is prevented from moving into initial state. Furthermore, the method comprises determining and setting timing settings for the first optical network device.

摘要： The invention relates to a system for transmitting a message from a source entity (ES) to a target entity (EC), said system comprising an input unit (UE) connected to the source entity in order to transmit the message via an optical transmission device (DTO) to an output unit (US) re-directing the message to the target entity. The system is characterised in that the optical transmission device can: transmit the message unidirectionally from the input unit to the output unit; and duplicate an optical input system containing the message into at least two optical output signals each containing the message to be transmitted to the output unit.
