Description

  The present invention analyzes a communication frame transmitted over a transport network, a communication frame transmitted from a transmission apparatus, a communication frame received by a transmission apparatus, etc., and detects errors or alarms generated in the transport network or transmission apparatus. The present invention relates to a transport analyzer that detects at least one and displays the detected error or alarm on a display screen provided in its own device, and more particularly relates to a transport analyzer that allows a user to reliably recognize a desired error or alarm.

  In transport network maintenance, management, research and development, etc., transmission is performed according to the standards of transmission systems (eg, SDH / SONET, OTN, etc.) defined by ITU-T (International Telecommunication Union-Telecommunication standardization sector). It is necessary to measure / analyze whether or not it is performed. A transport analyzer is used for such measurement / analysis (for example, see Non-Patent Document 1 and Non-Patent Document 2).

  The transport analyzer also performs measurement / analysis on transmission, reception, transmission / reception of the transmission apparatus, and measurement / analysis of the actual transport network itself.

  A transport analyzer (hereinafter abbreviated as “analyzer”) performs various measurements and analyzes of communication frames flowing through the transport network, and outputs (for example, displays on the display screen) errors and alarms. In SDH / SONET, OTN, and the like, errors / alarms to be detected are defined in the ITU-T standard, and there are tens to hundreds of items (types).

  On the other hand, the display screen of the analyzer is often provided on the front surface of the housing, but the size of the apparatus itself is about 10.4 inches due to the demand for miniaturization of the device itself.

  On the display screen, it is necessary to display not only the presence / absence of an error / alarm and detailed information on the error / alarm but also the measurement result / analysis result of the communication frame. For this reason, as for information on errors / alarms, only the item names are often displayed on the display screen.

  Here, FIG. 4 is a diagram showing an example of a display screen of a conventional analyzer. In FIG. 4, for example, three windows are displayed on the display screen, a window W1 is displayed in a narrow area at the left end of the display screen, and windows W2 and W3 are displayed in large areas on the upper and lower sides of the display screen. Is displayed.

  Only a few dozens to several hundreds of error / alarm information item names are displayed in the small window W1, and the measurement results / analysis results of the communication frame and detailed information on the errors / alarms are displayed in the large windows W2 and W3. The

  In the normal steady state, the transmission characteristics of the network are displayed in the windows W2 and W3. On the other hand, if there is an abnormality in the transmission characteristics of the network, the user can select an item in which an error / alarm has occurred from among a large number of items in the window W1 (for example, an item in which an error / alarm has occurred is red. And display an error / alarm item that seems to be the main cause of the abnormality, and display detailed error / alarm information of the selected item in the window W2.

Yukizawa Yanagisawa and three others, “40Gbit / s Next Generation Optical IP Transport Analyzer NX4000”, Yokogawa Technical Journal, Yokogawa Electric Corporation, published on October 22, 2007, Vol. 51, no. 4, p. 33-36 Yukizawa Yanagisawa and three others, “Measurement Application of 40Gbps Transport Analyzer NX4000”, Yokogawa Technical Journal, Yokogawa Electric Corporation, published July 25, 2008, Vol. 52, no. 3, p. 13-16

  In the case of measurement at the receiving side of the OTN frame, alarm items include, for example, OTU3 LOF, OTU3 OOF, OTU3 LOM, OTU3 OOM, OTU3 AIS, ODU3 LCK, ODU3 OCI, ODU3 AIS, OPU3 PLM, SM-TIM, SM-BIAE, SM-BDI, SM-IAE, ODU3 TCM (1-6) TIM, ODU3 TCM (1-6) BIAE, ODU3 TCM (1-6) BDI, ODU3 TCM (1-6) IAE, ODU3 TCM (1-6) LTC, ODU3 PM-TIM, ODU3 PM-BDI, etc.The error items include, for example, OTU3 FAS, SM-BIP8, ODU3 PM-BIP8, SM-BEI, ODU3 PM-BEI, ODU3 TCM (1-6) BIP8, ODU3 TCM (1-6) BEI, ODU2 (ad) PM-BIP8, ODU2 (ad) TCM (1-6) BIP8, ODU2 (ad) PM-BEI, ODU2 (ad) TCM (1-6) BEI, Corrected FEC error, Corrected 0, Corrected 1, Uncorrected FEC, etc.

  Thus, there are a very large number of error / alarm items, even only on the receiving side of the OTN frame. Then, the user sees the measurement result of the transmission characteristics, etc., selects an error / alarm item that seems to be related to an abnormal state in the communication line (transport network), the transmission device, etc. from the small window W1, and details in the window W2 Error / alarm information is displayed.

  However, for example, the case where there are four types of error items of priority “Err1”> “Err2”> “Err3”> “Err4” will be described. “Err1” has the highest priority. When the user selects “Err3” and enlarges and displays it on the window W2, even if “Err1” having a higher priority occurs, the item name of the window W1 is very small, so “Err1” There was a problem of not being able to recognize it without noticing that it occurred.

  In addition, because alarms / errors are detected according to the communication standard, when alarms / errors with high priority are occurring, errors with low priority may not occur (actually errors occur) However, it does not occur if the standard is followed.)

  Therefore, for example, when “Err3” is selected and enlarged and displayed in the window W2, “Err3” does not occur while “Err1” having a higher priority is occurring. Then, if the user does not notice that “Err1” has occurred in a small item in the window W1, there is a problem of giving the user a false recognition that no error / alarm has occurred.

  Furthermore, as described above, the priority order of errors / alarms is determined by the standard. However, there are cases where the user does not recognize the priority order accurately, and the error / alarm is displayed with the wrong priority order. There is a problem that the abnormal state of the transmission device cannot be analyzed.

  Therefore, an object of the present invention is to realize a transport analyzer that allows a user to reliably recognize a desired error or alarm.

Thereby, the user can be surely recognized an error or alarm having a desired priority. Therefore, it is possible to save time and effort for the user to select, and to reliably recognize the abnormality of the communication line and the transmission apparatus. Furthermore, it is possible to easily recognize the main cause that the communication line or the transmission apparatus is abnormal.

Embodiments of the present invention will be described below with reference to the drawings.
[First embodiment]
FIG. 1 is a block diagram showing a first embodiment of the present invention. In FIG. 1, a communication frame such as a transport network or a transmission device is input to an input unit 10. The data processing unit 20 receives a signal obtained by converting a communication frame from the input unit 10, measures and analyzes the communication frame, detects an error and an alarm in accordance with the communication standard, and analyzes the detected error and alarm. Do. The data memory 30 stores information on measurement results, analysis results, and detected errors / alarms processed by the data processing unit 20.

  The order storage means 40 stores priorities for each item of error and alarm. This priority order is defined by the communication standard. The selection means 50 reads out information about errors and alarms stored in the data memory 30 and the priority order stored in the order storage means 40, and selects any one of the error and alarm items read out based on the priority order. Select one item.

  The display processing unit 60 includes an item name display unit 61 and a detailed information display unit 62, reads information on measurement results, analysis results, and errors / alarms in the data memory 30, and an error / alarm selected by the selection unit 50. And the measurement result, analysis result, information on the error / alarm, and the like are displayed on the display screen 70.

  The item name display means 61 displays the item names of errors and alarms on the display screen 70 and refers to the data memory 30 to change the display of the item names of errors / alarms detected by the data processing unit 20.

  The detailed information display means 62 reads out detailed information regarding the error / alarm corresponding to the item selected by the selection means 50 from the data memory 30 and displays it on the display screen 70.

  The display screen 70 is provided on the front surface of the housing of the apparatus main body.

The operation of such an apparatus will be described.
The display processing unit 60 divides the display screen 70, for example, and generates and displays three windows W1 to W3 with an arrangement as shown in FIG. Then, the item name display means 61 displays a list of error / alarm item names defined in advance in the small window W1. Of course, if the display screen 70 itself is about 10 inches, a large number of item names are displayed. Therefore, the size of the area (box) for displaying the item name per item is very large, about several mm × several cm. It becomes a small rectangle.

  When a measurement start is instructed from an operation unit (not shown), the input unit 10 converts the communication frame so that the data processing unit 20 at the subsequent stage can process the communication frame. For example, if the communication frame is an optical signal, the optical signal is converted into an electrical signal, or the modulated communication frame is demodulated, analog / digital converted, and output to the data processing unit 20.

  Further, the data processing unit 20 performs data processing of the demodulated and AD converted data, and measures and analyzes transmission characteristics such as transmission delay time, bit error, mapping, and the like, and is defined in the communication standard. Error / alarm detection is performed for each error / alarm item, and the detected error / alarm is analyzed. Then, the data processing unit 20 stores the transmission characteristic measurement results, analysis results, detection results, detected error / alarm analysis results, and the like in the data memory 30.

  Then, the display processing unit 60 reads out the processing result of the data memory 30, and displays the measurement result / analysis result such as the transmission characteristics in the large windows W2, W3. Also, the item name display means 61 refers to the data memory 30, changes the display of the item name corresponding to the detected error / alarm, and displays it differently from the item name not detected. For example, the item name is changed to red, or the entire area (box) in which the item name is displayed is changed to red or the like. When a plurality of errors / alarms are detected, the display of all item names corresponding to them is changed.

  On the other hand, the selection means 50 refers to the data memory 30 and the order storage means 50, selects the error / alarm item with the highest priority from the detected error / alarm items, and selects the selected item name. Is output to the detailed information display means 62.

  As a result, the detailed information display means 62 reads out the detailed analysis result of the error / alarm corresponding to the selected item from the data memory 30 and displays it on the large window W2 of the display screen 70.

  Here, FIG. 2 is a diagram showing a display example of the display screen 70 of the apparatus shown in FIG. In FIG. 2, a small first window W1 is displayed at the left end of the screen, and a plurality of types of error / alarm item names are displayed. In the first window W1, the item name display means 61 displays the detected error / alarm item name area in red. In FIG. 2, as an example, two item names BEI (reference ErrA) and item name PLM (reference ErrB) are displayed in red.

  Since the priority order is “BEI”> “PLM”, the detailed information display means 62 expands the detailed information related to “BEI” having a high priority to the second window W2 to the second window W2. Is displayed.

  The third window W3 on the lower side of the screen displays measurement results, analysis results, and the like set by the user.

  Of course, when an error / alarm having a higher priority than both “BEI” and “PLM” is detected, the detailed error / alarm information of the item with the highest priority is obtained based on the selection result of the selection means 50. The detailed information display means 62 reads out from the data memory 30 and displays it in the second window W2.

  In this way, the selection means 50 refers to the priority order of the order storage means 40 and selects the item with the highest priority order from the currently occurring error / alarm items. Then, the detailed information display means 62 reads out the detailed error / alarm information corresponding to the item selected by the selection means 50 from the data memory 30 and displays it on the large second window W2 on the display screen 70. Thereby, it is possible to cause the user to recognize an error or alarm having a high priority. Accordingly, it is possible to save the user from having to select an item name having a high priority from among the item names in which errors / alarms are displayed in a small size, and to reliably recognize an abnormality in the communication line or the transmission device. .

  Moreover, since the detailed information display means 62 displays the item with the highest priority order on the display screen 70, it is possible to easily recognize the main cause that the communication line or the transmission apparatus is abnormal.

[Second Embodiment]
FIG. 3 is a block diagram showing a second embodiment of the present invention. Here, the same components as those in FIG. In FIG. 3, a mask means 80 is newly provided. The masking unit 80 masks a desired item from the errors / alarms and outputs the masked item to the selection unit 50.

The operation of such an apparatus will be described. Operations different from those of the apparatus shown in FIG. 1 will be mainly described.
The user sets an error / alarm item name to be masked from the operation unit (not shown) to the mask unit 80. For example, four types of errors “Err1” to “Err4” will be described. The priority is “Err1”>“Err2”>“Err3”> “Err4”, and “Err1” has the highest priority.

  For example, it is assumed that “Err2” is set in the mask unit 80 in the error / alarm item. For example, the data processing unit 20 detects errors “Err2”, “Err3”, and “Err4”, and stores the information in the data memory 30. Then, the selection unit 50 reads the error items “Err2”, “Err3”, and “Err4” detected from the data memory 30 and reads the priority order of the rank storage unit 40. Further, the item “Err2” masked by the mask means 80 is read. As a result, the error / alarm item with the highest priority is “Err2”, but the item masked by the masking means 80 is also “Err2”. Therefore, the selection means 50 excludes “Err2” and excludes “Err2”. The item “Err3” having the highest priority among “Err3” and “Err4” is selected, and the selection result is output to the detailed information display means 62. Then, the detailed information display means 62 reads out detailed information on the error / alarm related to the item “Err3” selected by the selection means 50 from the data memory 30 and enlarges it on the large window W2 of the display screen 70.

On the other hand, a case where errors “Err1”, “Err2”, and “Err4” are detected in the data processing unit 20 and the information is stored in the data memory 30 will be described. The selection means 50 reads the errors “Err1”, “Err2”, “Err4” detected from the data memory 30 and reads the priority order of the order storage means 40. Further, the item “Err2” masked by the mask means 80 is read. Then, the selection unit 50 selects the item “Err1” having the highest priority among the items “Err1” and “Err4” excluding “Err2” except for the item “Err2” masked by the masking unit 80, and selects the item “Err1”. The result is output to the detailed information display means 62. Then, the detailed information display means 62 reads out detailed information on the error / alarm related to the item “Err1” selected by the selection means 50 from the data memory 30 and enlarges it on the large window W2 of the display screen 70.
Since other operations are the same as those of the apparatus shown in FIG.

  As described above, the selection unit 50 selects the item having the highest priority from the items excluding the error / alarm item masked by the mask unit 80, and details of the error / alarm related to the selected item. Various information is displayed on the display screen 70 via the detailed information display means 62. As a result, for example, when the communication line or the transmission device is not stable, errors / alarms of specific items may occur frequently. However, by removing the errors / alarms of these specific items, it is really necessary. An error / alarm can be surely recognized by the user. Therefore, it is possible to save the user from having to select an item name that is really necessary and has a high priority, and it is possible to reliably and efficiently recognize an abnormality in the communication line or the transmission device. Furthermore, it is possible to easily recognize the main cause that the communication line or the transmission apparatus is abnormal.

The present invention is not limited to this, and may be as shown below.
(1) The configuration in which the mask means 80 has only one error / alarm item to be masked is shown, but any number of masks may be used.

(2) Although FIG. 2 shows an example in which two errors / alarms are detected, of course, any number may be detected.

(3) Although the detailed information display means 62 has shown the structure which displays the detailed information regarding the selected error / alarm on the upper window W2, it may be displayed not on the window W2 but on the lower window W3. .

(4) Although the display processing unit 60 has been configured to display three windows on the display screen 70, any number of windows may be displayed. Further, any arrangement of windows may be used.

(5) Although the item name display means 61 and the detailed information display means 62 have shown the structure which displays both an error and an alarm, only either one may be sufficient.

It is the block diagram which showed the 1st Example of this invention. It is the figure which showed the example of a display of the display screen 70 of the apparatus shown in FIG. . It is the block diagram which showed the 2nd Example of this invention. It is the figure which showed the example of a display of the display screen of the conventional apparatus.
