Note that: the example to be described next is only a specific example, and does not limit the embodiments of the present invention necessarily to the following specific steps, values, conditions, data, orders, and the like. Those skilled in the art can, upon reading this specification, utilize the concepts of the present invention to construct more embodiments than those specifically described herein.

The core idea of the embodiment of the invention is as follows: the transmission equipment converts the acquired constellation diagram data into hot spot diagram data, and transmits the hot spot diagram data to the management plane once after all acquisition tasks are finished.

Preferably, the transmission device converts the collected constellation diagram data into hotspot diagram data, and includes the following steps:

Preferably, the transmission device stores the acquired constellation diagram data as a lattice diagram array, and includes the following steps:

Preferably, the hot spot diagram is represented by a data structure of constellation diagram data of a maximum occurrence number + a maximum resolution + a two-dimensional array, subscripts of the two-dimensional array respectively represent horizontal and vertical coordinates of the constellation diagram, and array values of the hot spot diagram are relative values representing relative times of occurrence of the coordinate point at the maximum resolution.

The embodiment of the invention stores the acquired constellation diagram data into the dot diagram array, updates the dot diagram after the acquisition is finished each time, converts the dot diagram array into the hot spot diagram data after all the acquisition tasks are finished, and transmits the hot spot diagram data to the management plane for displaying at one time.

Preferably, after receiving the hotspot graph, the management plane draws and displays the constellation map in the hotspot graph.

The embodiment of the present invention further provides a data transmission system for a constellation diagram in an OTN transmission network, including a transmission device and a management plane, where:

a transmission device for: and converting the acquired constellation diagram data into hotspot diagram data, and transmitting the hotspot diagram data to a management plane once after all acquisition tasks are finished.

A management plane to: and after receiving the heat point diagram transmitted by the transmission equipment, drawing a constellation diagram in a heat point diagram mode and displaying the constellation diagram.

Referring to fig. 1, an embodiment of the present invention provides a data transmission method for a constellation diagram in an OTN transmission network, including the following steps:

the management plane issues a constellation diagram detection request, the transmission equipment continuously collects coordinate point data of the constellation diagram through the access optical device after receiving the request and reaching the detection starting time point, the collected constellation diagram data is stored as a dot-matrix diagram array, and the dot-matrix diagram array is updated again after the equipment collects the data each time. And after all the acquisition tasks are finished, the transmission equipment converts the dot-matrix array into hot spot map data and transmits the hot spot map data to the management plane once. And after receiving the hotspot graph data, the management plane displays the constellation graph data of the equipment by using a hotspot graph.

In the OTN transmission network, after a transmission device obtains a time period request which is issued by a management plane and needs to detect a constellation diagram, original coordinate point data of the constellation diagram is continuously obtained by an access optical device after a starting time point of a detection time period is reached, and the collected original coordinate point data of the constellation diagram is converted into a dot diagram array after each collection is finished.

The number of times of the coordinate points is recorded in the dot matrix array, the number of times of the coordinate points is changed along with the increase of the collection times, and a large amount of repeated data cannot be added.

And after the time period is over, converting the dot-matrix array into hot spot data according to the resolution required to be displayed and obtained from the management plane.

And the data value of the hot spot diagram is a relative value of the appearance of the coordinate point under the display resolution, and the coordinate point with the maximum appearance corresponds to the deepest color on the hot spot diagram.

And after all the collection tasks are finished, the transmission equipment sends the hotspot graph data to the management plane once and displays the hotspot graph data on the management plane.

In the OTN transmission network, the transmission equipment does not directly send the acquired constellation diagram data to the management plane in real time, but converts the acquired data into a hotspot format, and transmits the acquired data to the control plane for display once after the whole acquisition is finished.

The transmission device converts a large amount of collected data of the constellation diagram into a bitmap array, for example, 1000 points are collected at a time, the data format is (x0, y0), (x1, y1) to (xi, yi), wherein 0< i <1000, and xi, yi are 8-bit unsigned 2-ary numbers, and the data can be converted into a two-dimensional array, such as a [ x ] [ y ], wherein x and y have a value ranging from 0 to 255 (8 powers of 2), and a [ x ] [ y ] is the number of occurrences.

After the transmission equipment converts the constellation diagram data into the dot matrix diagram array, when the data is collected again, the constellation diagram data does not increase, only the value of a [ x ] [ y ] needs to be corrected, the size of the data for storing the constellation diagram information is 256 × 256 all the time, which represents the bit length of the maximum number of times of occurrence of the dots, for example, 16 bits represents the number of occurrence, and the data amount of the dot matrix diagram is 256 × 16 bits 1048576 bits all the time, which does not increase and increase along with the collection amount. If the test is carried out for 10 hours, the test is carried out once every 1 minute, and the test is directly reported in a traditional mode, wherein the data volume is 10 × 60 × 1000 × 8+ 8bit (9600000 bit), and is more than 9 times of the data of the dot-matrix.

And when the transmission equipment receives a request for acquiring the accumulated constellation data issued by the management plane, converting the bitmap data into a hotspot map data format. The two-dimensional array of the bitmap data is, for example, a [ x ] [ y ], wherein the value range of x and y is 0 to 255 (8 th power of 2), and a [ x ] [ y ] is the occurrence number. The data format after being converted into the heat map is time _ max + diff _ max + b [ x ] [ y ], wherein the time _ max is the occurrence frequency of the highest point of the bitmap data, the diff _ max is the bit number of the data b [ x ] [ y ], and the b [ x ] [ y ] value is the relative frequency. Converting to the format of the heat-point diagram data, the difference of the appearance probability of two coordinate points can be easily obtained, such as (b [ x2] [ y2] -b [ x1] [ x1 ])/2 to the power of diff _ max.

The transmission equipment transmits the hotspot graph to the management plane according to the agreed protocol format, so that the data volume can be transmitted according to the data resolution required by the management plane, and the data transmission volume is saved.

For example, the management plane has only 8-bit color resolution, i.e., 8 powers of 2, 256 colors, and only 256 colors to distinguish the occurrence times of a coordinate point, and the highest actual occurrence times need to be represented by 16-bit data, and when the dot diagram is converted into the hot spot diagram, the data size is reduced from the data size of 256 × 16 bits of the dot diagram to the data size of 2+1+256 × 8 bits of the hot spot diagram. After receiving the hot spot map data, the management plane can directly draw the constellation map in a hot spot map mode.

The embodiment of the invention provides a new constellation diagram data transmission mode, which realizes the conversion from constellation diagram data to hot spot diagram data and can effectively reduce the data transmission quantity when monitoring the accumulative constellation diagram in a transmission system.

For example, once every 24 hours and once every 1 minute, the transmission device obtains a constellation data monitoring of 1000 coordinate points with 8 bits, and the management plane may draw an image with 256 colors, in this case, if a conventional direct reporting manner is adopted, the constellation data amount is 24 × 60 × 1000 × 16 — 23040000bit, and the embodiment of the present invention adopts a transmission manner of a hotspot graph, and the data amount is 4+1+256 × 8 — 524293bit, so that the transmitted data amount is significantly reduced.

As a preferred embodiment, as shown in fig. 1, the transmission device creates an initial bitmap and a hot spot map to be displayed from the start of receiving the constellation diagram monitoring command, and stores the sampling start time, the display start time and the display end time.

When the transmission device creates a bitmap, it may be implemented by initializing a 2-dimensional lattice array, for example:

wide，high，start_time,

{data[0][0],data[0][1],…,data[0][wide-1]},

{data[1][0],data[1][1],…,data[0][wide-1]},

…

{data[high-1][0],data[high-1][1],…,data[high-1][wide-1]}

wherein, wide is the maximum length of the constellation diagram in the x-axis direction, high is the maximum length of the constellation diagram in the y-direction, start _ time is the test start time, and data [ x ] [ y ] is the frequency of the coordinate point (x, y) appearing from the beginning to the present acquisition process, wherein x is less than wide, and y is less than high.

The format of the hotspot graph in the embodiment of the invention is as follows:

{time_num，wide，high，

{time_idex,start_time,end_time,max_time，diff_max，

{data_brn[0][0],data_brn[0][1],…,data_brn[0][wide-1]},

{data_brn[1][0],data_brn[1][1],…,data_brn[0][wide-1]},

…

{data_brn[high-1][0],data_brn[high-1][1],…,data_brn[high-1][wide-1]}

}

the time _ num is the number of hot spots which need to be displayed in total, if a certain acquisition needs to display a constellation diagram of each day in 3 days from the beginning to the end of the acquisition, at this time, the time _ num is 3, if the 3-day constellation diagram needs to be obtained, the time _ num is 1, wide is the maximum length of the constellation diagram in the x-axis direction, high is the maximum length of the constellation diagram in the y-direction, time _ idex is an index of specific display times, diff _ max is the bit number of data b [ x ] [ y ], start _ time is accumulated start time, end _ time is end time, max _ time is the maximum number of times of occurrence of a time period point corresponding to the time _ idex, and data _ brn is the relative frequency of the specific coordinate point.

If the transmission device collects 1000 coordinate points at a time and once per minute, the original data of constellation coordinates are collected at 1000 × 60 × 24 point binary data every 1 day, for example, (x0, y0), (x1, y1) to (xi, yi), where 0< i <1000 and xi, yi are 8-bit unsigned 2-ary numbers, 2018-06-0110: 20 starts to collect, 0 appears at 0,0 appears at (0, 0) 1 appears at (0, 1) 0 appears at (0, 255) 0 appears at (255, 0) 0 appears at (255, 1) 10 appears at (255 ) 0 appears at (100 ) 255 appears at the highest point, 255 appears at 2018-06-0210: 20 ends to collect, and only one time is accumulated.

The dot-matrix diagram would be:

8，8，2018-06-01 10:20

{0,1，...，0}

...

{0,10，...，0}

the hotspot graph would be:

{1，8，8，

{0,2018-06-01 10:20,2018-06-02 10:20,256，8

{0,1，...，0}

...

{0,10，...，0}

}

if the transmitting device collects 1000 coordinate points at a time and once per minute, the raw data of the constellation coordinates collected in 2 days are 1000 × 60 × 24 × 2 point binary data, for example, (x0, y0), (x1, y1) to (xi, yi), where 0< i <1000 and xi, yi are 8-bit unsigned 2-ary numbers, 2018-06-0110: 20 starts to collect, (0, 0) point appears 0 times, (0, 1) point appears 2 times, (0, 255) point appears 0 times, (255, 0) point appears 0 times, (255, 1) point appears 30 times, (255 ) point appears 0 times, highest point (100 ) appears 511 times, and 2018-06-0310: 20 ends to collect, and only once accumulates.

The dot-matrix diagram would be:

8，8，2018-06-01 10:20

{0,2，...，0}

...

{0,30，...，0}

the hotspot graph would be:

{1，8，8，

{0,2018-06-01 10:20,2018-06-03 10:20,512，8

{0,1，...，0}

...

{0,15，...，0}

}

after the collection time starts, the transmission device completes the collection and reporting of the constellation data according to the flow shown in fig. 2.

The management plane sends a constellation diagram test to start, the test time is 10 hours, the accumulated constellation diagram data is reported once per hour,

the transmission equipment receives the command to start acquisition, acquires the single disc once per minute, stores the received constellation diagram into the bitmap, and reports the time for 1 hour.

And the transmission equipment converts the dot diagram into a hot point diagram, and the test is finished after the test time reaches the report of the hot point data of the total constellation diagram.

If the test has only one accumulated report, the active report of the accumulated graph for 1 hour is not carried out, and the report is carried out when the test is finished and the collection is finished.

Fig. 2 adopts a completely new algorithm, and the transmission device converts the acquired constellation diagram data into hot spot diagram data, wherein the algorithm for converting the constellation diagram acquired data into a dot matrix diagram is as follows:

inputting: n constellation points (x, y), i ═ 0, known as wide, high

A. Obtaining the x and y values of the ith point;

B. obtaining xi and yi of the lattice corresponding to the sampling point according to the wide and high values, wherein if the value range of x is 0-wide and y is 0-high, xi is equal to x, and yi is equal to y;

C. data [ xi ] [ yi ] plus 1, i is smaller than n and jumps to A;

D. and (5) ending traversal and exiting.

If wide is 3 and high is 3, the constellation point n is 10, which is {0,1}, {1,0}, {1,0}, {1,1}

{1,1}，{1,1}，{1,2}，{1,2}，{2,1}

Starting to create a [3] [3] ═ 0}, firstly traversing coordinate points, and if the coordinate points are traversed to the 4 th point {1,1}, obtaining xi ═ 1, and yi ═ 1; a1 to 1 from plus 1; if the 5 th point is traversed, a [1] [1] is added with 1 to 2 again, and the data after the above processing is as follows:

a[3][3]＝

{

0,1,0

2,4,2,

0,1,0

}

the algorithm for converting the acquired dot-matrix data into the heat-point map by the transmission equipment is as follows:

a. inputting: the start time lattice map data1[ x ] [ y ] and the time start _ time, the end time lattice data2[ x ] [ y ] and the time end _ time;

b. the transmission equipment obtains a cumulative time slot bitmap data [ x ] [ y ] ═ data2[ x ] [ y ] -data 1[ x ] [ y ];

c. traversing the dot matrix, wherein the maximum date [ x ] [ y ] value is the maximum times point max _ time;

d. the transmission equipment obtains the relative frequency according to data _ brn [ x ] [ y ] (diff _ max power of 2-1) × ate [ x ] [ y ]/max _ time;

e. the transmission device stores the obtained data _ brn [ x ] [ y ], max _ time, start _ time and end _ time in the hotspot graph.

For example, the bitmap is empty at the beginning, and the current bitmap is, for example, data2[3] [3] }

a[3][3]＝

{

0,1,0

2,3,2,

0,1,0

}

And the starting time 2018-06-0110: 20, the ending time 2018-06-0310: 20, and the resolution of 2 bits of the management plane.

In step b

data[3][3]＝

a[3][3]＝

{

0,1,0

2,3,2,

0,1,0

}

In step d, max _ time is 3 and diff _ max is 2, and the result is obtained

data_brn[3][3]＝

{

0,1,0

2,3,2,

0,1,0

}

The transmission device obtains hotspot graph data.

The constellation diagram image directly displayed at present can not distinguish the repeated appearance times of the coordinate points in the image, the constellation diagram data is directly transmitted to the management plane, and the management plane repeatedly draws the repeated appearance points on the constellation diagram during display. For example, the conventional method can reflect whether 16 coordinates with (xi, yi) as the center and 4 widths are some points, and cannot reflect the situation when 16 coordinates are all some points and the repeated occurrence times of the points are greatly different.

In a preferred embodiment, after receiving the data of the hotspot graph, the management plane displays the data in a hotspot graph mode (the relative times of appearance are indicated by light and dark colors) or performs other processing according to requirements.

For example, when the management plane draws an image, the shade of color is represented by a mixture of red RGB (255,0,0) and white (255 ), the resolution of the color issued by the management plane to the transmission device is 8 bits, and the color drawn on the coordinate point pixel is RGB (255, 255-relative frequency), wherein the relative frequency is the value of data _ brn [ x ] [ y ] in the hotspot graph.

For another example, when the management plane draws an image, the shade of color is expressed by a mixture of black RGB (0,0,0) and white (255 ), the management plane issues 8 bits of resolution of the color to the transmission device, and the color drawn on the coordinate point pixel is RGB (relative frequency ) which is the value of data _ brn [ x ] [ y ] in the heat map.

And ending the sampling when the sampling end time is up.
