Specifically, the first FlexE module can be the first FlexE bed course, and the 2nd FlexE module can be the 2nd FlexE Bed course.It is appreciated that FlexE bed course is in the function that the function of sending direction is exactly that FlexE multiplexer (FlexE mux) is completed Can, FlexE bed course is in the function that the function of receiving direction is exactly that FlexE demultiplexer (FlexE demux) is completed.In the application In embodiment, the function of the first FlexE module and the achievable FlexE mux and FlexE demux of the 2nd FlexE module.When When first FlexE module sends information (for example, message or request) to the 2nd FlexE module, the first FlexE module is completed The function of FlexE mux, when the first FlexE module receives the information (for example, message or response etc.) that the 2nd FlexE module is sent When, the first FlexE module completes the function of FlexE demux.Similarly it is suitable for the 2nd FlexE module.In the embodiment of the present application In, it is all when being related to the first FlexE module or the 2nd FlexE module and sending information, that is, show that it completes the function of FlexE mux Energy；It is all when being related to the first FlexE module or the 2nd FlexE module and receiving information, that is, show that it completes the function of FlexE demux Energy.

It should be noted that the first FlexE module is also possible to the first FlexE mux, the 2nd FlexE module is also possible to 2nd FlexE demux.What it is due to FlexE mux completion is function of the FlexE bed course in sending direction, and FlexE demux What is completed is function of the FlexE bed course in receiving direction, therefore, when the first FlexE module sends information to the 2nd FlexE module When, the first FlexE module directly refers to FlexE mux (obscuring in order to prevent, referred to as the first FlexE mux), the 2nd FlexE Module directly refers to FlexE demux (obscuring in order to prevent, referred to as the 2nd FlexE demux), and the first FlexE mux is direct Information is sent to the 2nd FlexE demux.When the first FlexE module receives the information that the 2nd FlexE module is sent, first FlexE module may also mean that the first FlexE mux, and the 2nd FlexE module may also mean that the 2nd FlexE demux.Only Here the first FlexE mux does not receive the information that the 2nd FlexE demux is directly transmitted, the first FlexE mux not instead of directly The information received and sent between the 2nd FlexE demux of indirect reception.Specifically, the first FlexE mux passes through the first FlexE demux Receive information；2nd FlexE demux sends information by the 2nd FlexE mux.Wherein, the first FlexE demux is completed It is the receive capabilities of the first FlexE module, what the 2nd FlexE mux was completed is the sending function of the 2nd FlexE module.

In addition, the first FlexE module is properly termed as sending FlexE bed course, the 2nd FlexE module is properly termed as receiving FlexE bed course.But the function that " transmission " and " reception " herein is not completed the FlexE module during specific implementation is made Limitation.

The above-mentioned description as described in the first FlexE module and the 2nd FlexE module is suitable for multiple realities described in this statement Apply example.To simplify the description, it is directly illustrated in subsequent embodiment with the first FlexE module and the 2nd FlexE module.

Specifically, above-mentioned switching request is to switch to the switching request of the first bandwidth assignment configuration.It specifically can be by more Change the value of " CR " bit in FlexE expense frame to issue request.Alternatively, other marks can also newly be defined to indicate that switching is asked Ask, method be it is similar, repeat no more.It is recognised that currently used bandwidth allocation is configured to the configuration of the second bandwidth allocation.? In the embodiment of the present application, the first bandwidth assignment configuration can be aforementioned B configuration, and the configuration of the second bandwidth allocation can be aforementioned A and match It sets；Or first bandwidth assignment configuration can be aforementioned A configuration, the configuration of the second bandwidth allocation can be aforementioned B configuration.In this Shen It please be B configuration with the first bandwidth assignment configuration in embodiment, the second bandwidth allocation is configured to be illustrated for A configuration.At this point, The value of " CR " bit is changed to " 1 " by " 0 ", it is meant that the first FlexE module switches to first band to the transmission of the 2nd FlexE module The switching request of wide assignment configuration.

Specifically, the first FlexE module can be since the same expense frame of all FlexE examples, will be in FlexE group The value of " CR " bit of all FlexE examples is changed to the value of the mark of the first bandwidth assignment configuration.Same expense frame refers to The FlexE expense frame that all FlexE examples are being handled in synchronization FlexE group.Synchronization herein is using the second as timing Unit, since the transmission of FlexE expense frame is carried out as unit of millisecond, above-mentioned synchronization can not limit all The stringent synchronization of the FlexE expense frame that FlexE example is being handled in time.Specifically, from the same of all FlexE examples Expense frame starts, and the value of " CR " bit of all FlexE examples in FlexE group is changed to the mark of the first bandwidth assignment configuration The value of knowledge refers to " CR " ratio in expense frame by the same expense frame of all FlexE examples in FlexE group and its later Special value is changed to the value of the mark of the first bandwidth assignment configuration.
