After the scrambling code, the 64Bit code block is converted into 66Bit code block. During the conversion process, the alignment code block is inserted, and then converted into a 100G adapter unit interface by bit multiplexing (100 Gigabit Attachment Unit Interface, CAUI) data; Physical Medium Attachment (ΡΜΑ) adapts CAUI interface data; Physical Medium Dependent (PMD) transmits adapted signals through the same physical layer channel .

102. The data distribution device determines, according to a rate of the MAC data frame bitstream corresponding to the service identifier, a physical layer channel corresponding to the MAC data frame bitstream corresponding to the service identifier.

If the MAC data frame bit stream carries multiple service identifiers, the MAC data frame bit stream may be firstly divided according to the service identifier, and divided into MAC data frame bit streams corresponding to the service identifier.

In the embodiment of the present invention, if the MAC data frame bit stream includes multiple MAC data frame bit streams, the rate of each MAC data frame bit stream may be different. When some MAC data frame bit streams need to occupy a large bandwidth, it is required. When a physical layer channel of a larger bandwidth is used to carry, or a physical layer channel cannot carry a MAC data frame bit stream with a large rate, multiple physical layer channels are required to be carried. If the rate of the bit stream of the MAC data frame is 200 Mbit/s, it is determined that the total carrying capacity of the physical layer channel corresponding to the bit stream of the MAC data frame is 200 M. If a physical layer channel can carry 50 M, the MAC data can be determined. The frame bit stream corresponds to 4 physical layer channels.

103. The data distribution apparatus sends a corresponding MAC data frame bitstream to a physical layer channel corresponding to the MAC data frame bitstream corresponding to the service identifier.

After the physical channel of the MAC data frame bit stream or the physical layer channel of the MAC data frame bit stream is determined, the corresponding MAC data frame bit stream or the MAC data frame bit stream is transmitted to the corresponding physical layer channel.

The embodiment of the present invention uses the media access control MAC data frame bit stream carrying the service identifier; and determines the MAC data frame bit stream corresponding to the service identifier according to the rate of the MAC data frame bit stream corresponding to the service identifier. The physical layer channel sends a corresponding MAC data frame bit stream to the physical layer channel corresponding to the MAC data frame bit stream corresponding to the service identifier. Compared with the method for processing data by the virtual channel alignment in the prior art, the data processing method provided by the embodiment of the present invention can transmit data of the same service identifier through multiple physical layer channels, thereby reducing the complexity of data processing and improving The efficiency of data processing.

Mapping table between the service identifier and the channel number of the physical layer channel

The physical layer channel corresponding to the MAC data frame bit stream with the service identifier 1 in Table 1 is three, which are physical layer channels with channel numbers 1, 2, and 3.

In this way, when the service identifier is 1, the physical layer channel corresponding to the MAC data frame bit stream with the service identifier 1 is 1, 2, 3, and the MAC data frame bit stream corresponding to the service identifier 2 is corresponding. The physical layer channel is 4, the physical layer channel corresponding to the MAC data frame bit stream with the service identifier 3 is 5, and the physical layer channel corresponding to the MAC data frame bit stream with the service identifier 4 is 6.

When the rate of the MAC data frame bit stream with the service identifier 1 is not greater than the total carrying capacity of the physical layer channel corresponding to the MAC data frame bit stream corresponding to the service identifier 1, the channel number corresponding to the service identifier 1 is 1. The physical layer channel of 2, 3 is determined as the physical layer channel of the MAC data frame bit stream with the service identifier 1. For example: When the rate of the MAC data frame bit stream with service ID is 1 is 130 Mbit/s, and the total 7-load capacity of the physical layer channel with channel number 1, 2, 3 is 150 M, the channel number can be determined as 1, 2, 3 The physical layer channel is a physical layer channel of a MAC data frame bit stream with a service identifier of 1.

The process of determining the physical layer channel for the MAC data frame bit stream with the service identifiers of 2, 3, and 4 is the same as the process for determining the physical layer channel for the MAC data frame bit stream with the service identifier of 1, and will not be described in detail herein.

Optionally, in the second optional embodiment of the data processing method provided by the embodiment of the present invention, the MAC data frame bit corresponding to the service identifier is used in the foregoing.

The physical layer channel with the channel number of 1, 2, and 3 is not enough to carry the MAC data frame bit stream with the service identifier of 1. The at least one physical layer channel can be selected from the available physical layer channels that are not used, for example, the channel number is 7. The physical layer channel is the available physical layer channel, and the physical layer channel with channel number 7 has a carrying capacity greater than 30M. Thus, it can be determined that the physical layer channel of channel numbers 1, 2, 3, and 7 is the MAC data with the service identifier 1 The physical layer channel of the frame bitstream.

The channel number of the layer channel is associated with the service identifier, and the associated channel number of the at least one physical layer channel and the service identifier are stored in the mapping table.

In the embodiment of the present invention, the mapping table after the association storage can be understood by referring to Table 2:

Table 2: Modified mapping table

As can be seen from Table 2, the relationship between service identifier 1 and channel number 7 is shown.

Of course, the above is only an example of the physical layer channel of channel number 7. In fact, the bit stream of the MAC data frame can be never carried.

Optionally, in the fourth optional embodiment of the data processing method provided by the embodiment of the present invention, based on the foregoing first optional embodiment corresponding to FIG. 2:

And when the rate of the MAC data frame bit stream corresponding to the service identifier is not greater than the total carrying capacity of the physical layer channel corresponding to the MAC data frame bit stream corresponding to the service identifier, the physical layer channel corresponding to the service identifier is used. Determining, as the physical layer channel corresponding to the MAC data frame bit stream corresponding to the service identifier, the method may include:

Layer 7 channels, the capacity of the three physical layer channels is 50M, 60M, and 70M respectively. When the rate of the MAC data frame bit stream corresponding to service identifier 1 is 100M, the physical layer channel with channel numbers 1 and 2 can be selected. To transmit the MAC data frame bit stream corresponding to the service identifier 1, or to select the physical layer channel with the channel number 2 and 3 to transmit the MAC data frame bit stream corresponding to the service identifier 1, or select the physical medium with the channel number 1 and 3. The layer channel transmits the MAC data frame bit stream corresponding to the service identifier 1, but the total carrying capacity of the physical layer channel with the channel numbers 1 and 2 is 110M, and the channel number is a combination of 1 and 2 compared with the other two combinations. The total bearer of the physical channel has the smallest difference from the rate of the MAC data frame bitstream corresponding to the service identifier 1, only 10M, then the physical layer channel of the channel number 1 and 2 is selected as the MAC data frame bitstream corresponding to the service identifier 1. Physical layer channel.

In the embodiment of the present invention, it is required to ensure that the determined physical layer channel can be used normally. Therefore, before determining the physical layer channel corresponding to each service data flow, it is necessary to first detect whether each physical layer channel has a fault, and if there is a fault. It cannot be used. The fault information of the channel can be stored in the corresponding channel number of the physical layer channel in the mapping table to avoid being misused. If the physical layer channel with channel number 3 fails and the other physical layer channels are in normal use, the storage status information in the mapping table can be understood by referring to Table 4:

In the embodiment of the present invention, after detecting that there is a fault in the physical layer channel with the channel number 3, the channel number of the physical layer channel corresponding to the channel number 3 is selected from the available physical layer channels that are not used. The physical layer channel is added to the mapping table 4 corresponding to the service identifier 1 and the channel number 7. The status information corresponding to the channel number 7 is changed to "new", and the physical layer channel corresponding to the channel number 7 is activated, and a new one is obtained.

Table 5: Adjusted mapping table

In this embodiment, when the physical layer channel is replaced, the one-to-one replacement is used, for example, the physical layer channel corresponding to the channel number 3 is the same, and the physical layer channel data may not be considered.

For example, the 7-load capacity of the physical layer channel corresponding to channel number 3 is 50M, and the total load capacity of the physical layer channel corresponding to channel numbers 9 and 10 is 50. You can replace the channel with the physical layer channel corresponding to channel numbers 9 and 10. No. 3 corresponds to the physical layer channel.
