One of the methods for mapping customer traffic into an OSU container is BMP mapping, and conventional BMP mapping employs a unique mapping pattern for a specific traffic, i.e., the OSU data frame structure filled into OSU blocks is fixed. The frame structure of the OSU data includes an overhead region (OH), a payload region (payload), and a padding region (stuff), and the payload amount padded to the payload region is unchanged by using a conventional BMP mapping method.
However, since one block of the OSU container is large, the entire OSU block needs to be filled when the client service is mapped to the OSU container, and if the traditional BMP mapping method of the OTN is used and a unique mapping pattern is adopted, the time for generating one OSU block by the low-speed service is long, and the service delay is large.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1, an embodiment of the present invention provides a method for implementing a time-delay adaptive BMP mapping, including determining, according to a preset adaptive policy, a payload size, that is, a mapping pattern, of a payload area of an OSU data block that matches a client service bandwidth, and generating OSU data blocks with different payload quantities according to corresponding mapping patterns when performing BMP mapping on client service data with different client service bandwidths. The self-adaptive strategy is to judge the bandwidth range to which the client service bandwidth belongs, and determine the payload according to the bandwidth range, wherein the larger the boundary value of the bandwidth range is, the larger the payload is. For high-speed service, the payload quantity of OSU data block is large, for low-speed service, the payload quantity of OSU data block is small, and the mapping pattern can be flexibly changed according to different services, so that different delay characteristics can be generated for different services.
Continuing to refer to fig. 1, an embodiment of a delay-adaptive BMP mapping implementation method is provided, where the method includes:
and step S1, obtaining the net load corresponding to the client service bandwidth according to the preset adaptive strategy.
And step S2, processing according to the payload and the bit width data to obtain the shift byte number, the high pointer and the low pointer.
And step S3, sequentially caching the client service data into N-1 RAMs in a form of bit width data. Wherein, N is the number of bit-wide data which is contained in the OSU data volume transmitted in one transmission cycle at most, and the OSU data block includes the OSU data volume transmitted in at least one transmission cycle.
And step S4, respectively acquiring bit width data from n-1 RAMs, shifting each bit width data according to the number of shift bytes to obtain shift data, intercepting effective data from each shift data according to a high pointer and a low pointer, splicing n effective data and filling the effective data to a payload area of an OSU data block, and filling an overhead area and a filling area of the OSU data block to obtain the OSU data block. Wherein N is a positive integer not greater than N.
The block sizes of OSU data blocks corresponding to different client service bandwidths are the same.
In this embodiment, the payload is the number of bytes of payload in the OSU data block, and the smaller the client service bandwidth is, the smaller the number of bytes of payload in the OSU data block is, the larger the client service bandwidth is, the larger the number of bytes of payload in the OSU data block is.
The method for generating payload by client service bandwidth set by the adaptive strategy is as follows: when the client service bandwidth is larger than the bandwidth B1 and is smaller than or equal to the bandwidth B2, a specific payload D1 is generated; when the customer traffic bandwidth is greater than the bandwidth B2 and less than or equal to the bandwidth B3, another specific payload amount D2 is generated. Where bandwidth B1< bandwidth B2< bandwidth B3, a number of specific payload quantities D1, D2 … … may be generated. The payload amount is minimum 1 and maximum is the length of the OSU data block minus the length of the OH field in the OSU data block.
The number of bytes of payload in the OSU data block has a direct influence on the transmission delay of the client service. Specifically, assuming that the client service bandwidth is 2Mbit/s, the length of the OSU data block is 192 bytes, and the length of the OH field in the OSU data block is 7 bytes, if the byte number of the payload in the OSU data block is 64, the client service needs to transmit 64 bytes to generate a complete OSU data block, and the time for transmitting 64 bytes by the client service is 64 bytes 8 bits/2 Mbit/s 256 us. If the byte number of payload in the OSU data block is 128, the client service needs to transmit 128 bytes before generating a complete OSU data block, and the time for transmitting 128 bytes by the client service is 128 bytes 8 bits/2 Mbit/s 512 us.
Therefore, when the byte number of payload in the OSU data block is 64 bytes and 128 bytes, the delay between the two is 512-. Therefore, the smaller the byte number of payload in the OSU data block, the smaller the time required for generating an OSU data block, and the smaller the client service delay, the larger the byte number of payload in the OSU data block, the larger the time required for generating an OSU data block, and the larger the client service delay. For low-speed service, the byte number of payload in an OSU data block is adaptively reduced, so that the delay of the client service in the process of mapping to the OSU can be effectively reduced, and the better delay performance is achieved.
Based on the foregoing embodiment, with continued reference to fig. 1, a specific operation of sequentially caching the client service data in the form of bit width data into N-1 RAMs in step S2 is described by a specific embodiment:
the N-1 RAMs can form an RAM cache unit 3 for caching client service data of different client services, the client services are transmitted in corresponding transmission channels in the form of the client service data, and the client service bandwidth is the bandwidth of the transmission channels. During specific transmission, each transmission channel transmits one bit wide data in a corresponding transmission cycle. The client service data of each client service comprises current bit width data, previous first bit width data and previous N-1 bit width data of the previous second bit width data … …, the current bit width data can be directly used without being stored in the RAM cache unit 3, the RAM _1 stores the previous first bit width data, and the RAM _2 stores the previous second bit width data … …, the RAM _ N-1 stores the previous N-1 bit width data.
In each of the RAMs RAM _1 to RAM _ N-1, each customer service occupies 2 address spaces, and the size of each RAM space is 2 × the number of customer services. For example, channel 0 occupies address 0 and address 1 of each RAM space, channel 1 occupies address 2 and address 3 of each RAM space, and so on.
The realization of the time delay self-adaptive function can generate various OSU mapping patterns, is realized by using an RAM chain and a flow method, can optimize the time sequence, and can flexibly generate the mapping patterns of various OSU data blocks.
Based on the foregoing embodiment, with continuing reference to fig. 1, the specific operations of obtaining the number of shift bytes, the high pointer, and the low pointer according to the payload amount and the bit width data processing in step S2 are described by specific embodiments:
it is assumed that the client service data is transmitted by 80 bytes in one transmission cycle and the OSU data is transmitted by 128 bytes in one transmission cycle. Assume that the length of an OSU block is 256 bytes, with an OH field of 8 bytes, a payload field of 210 bytes, and a stuff field of 38 bytes. An OSU data block requires 2 transmission cycles to complete, the first transmission cycle transmitting an OH field of 8 bytes and a payload of 120 bytes, and the second transmission cycle transmitting a payload of 90 bytes and a stuff of 38 bytes.
Taking the case that the transmission channel 0 continuously inputs 1 st to 6 th customer service data as an example, the read-write signal of each RAM is as follows: 1-5 customer service data inputted by the transmission channel 0 are alternately written into the address 0/1 space of the RAM _1, and the read address of the RAM _1 is obtained by inverting the write address. After the RAM _1 performs the read operation, the read data is output with 2 transmission cycles being delayed. And delaying the read-write signal of the RAM _1 for 2 transmission cycles to obtain a read-write signal of the RAM _2, wherein the data content written in the RAM _2 is the data content read out from the RAM _ 1. After delaying again for 2 transmission cycles, the output data of RAM _2 will be obtained. Delaying the output data of the RAM _1 by 2 transmission cycles and delaying the client service data by 4 transmission cycles, thus obtaining all data of the payload amount required for the BMP mapping later in the same transmission cycle. According to the payload and the bit width data, the number of shift bytes can be processed by combining the storage capacity of each RAM, and the high pointer and the low pointer can be used for intercepting effective data from the bit width data to fill the payload area of the OSU data block. The high pointer indicates that OSU data is generated starting from the several bytes of the bit-wide data and the low pointer indicates that OSU data is generated ending from the several bytes of the bit-wide data.
Based on the foregoing embodiment, with continuing reference to fig. 1, the specific operation of padding the payload area of the OSU data block in step S4 is described by a specific embodiment:
when BMP mapping is carried out on customer service data, current bit width data is obtained, the bit width data is obtained from N-1 RAMs respectively, each bit width data is shifted according to the number of shift bytes to obtain shift data, effective data is intercepted from each shift data according to a high pointer and a low pointer, N effective data are spliced and filled into a payload area of an OSU data block to obtain the OSU data block, wherein N is a positive integer not larger than N. The n valid data include the current bit width data and the previous bit width data obtained from the n-1 RAMs.
Based on the foregoing embodiment, with continuing reference to fig. 1, a specific operation of generating the OSU data block in step S4 is described by a specific embodiment:
and filling the overhead area and the filling area of the OSU data block to obtain the OSU data block after filling the payload area of the OSU data block according to the payload quantity.
In some other embodiments, after the payload region of the OSU data block is filled according to the payload amount, only the overhead region of the OSU data block may be filled. Whether to populate a populated area of the OSU database may be customized.
