The embodiment of the application provides a method for acquiring flow statistical results in a packet network and an optical transport network, which is applied to a flow statistical result acquisition device, messages of various types of data flows and protocols can be sent as required when module testing is carried out, the messages can generate changes after passing through a tested system, and whether the changes are correct is judged by verifying the field value of the received data flow, the receiving rate of the data flow and the like. All data stream reception statistical functions need to be written to process the data streams expected to be received, and receive information of the data streams is obtained, such as: l1 rate, number of received frames, number of lost packets, etc.
In the embodiment of the application, the flow statistical results of the data flows of all data types are obtained through two functions; the two functions have good expansibility and portability. Any data stream matching the field and field value can be looked up and also looked up according to the name of the data stream, and the actual value of a certain field of the return receiving stream can also be specified. The attribute of the sending and receiving result information of the returned data stream can be added at will, so that the method has good expansibility. The function is not dependent on specific transceiving value matching, so that the function is suitable for all flow result analysis, and all module flow analysis can use the function.
When the method is realized, the two functions can be called a first function and a second function;
wherein the function of the first function is: matching the data stream according to the field of the data stream to obtain a corresponding statistical result, and returning the field value of the field;
such as may be: STC _ classificationsisttics function, but is not limited to the implementation of this function.
The function of the second function is: acquiring a flow statistic result of the data flow according to the flow identification;
such as may be: the STC _ detailedstearstatlnformation function, but is not limited to implementation of the function.
The flow statistics obtaining process in the embodiment of the present application is described in detail below with reference to the accompanying drawings.
Example one
Referring to fig. 1, fig. 1 is a schematic view illustrating a flow statistical result obtaining process in an embodiment of the present application. The method comprises the following specific steps:
After the matching entry is obtained, the content included in the matching entry needs to be determined, and if it is determined that the matching entry includes the corresponding relationship between the port identifier and the data stream matching entry, step 102 is executed.
The first handle list is used for storing a statistical result of the port receiving data flow.
In an interface of a tester, analysis flow statistics results are port-based, a statistics result of each port can exist in one analyzer result handle, and the situation of receiving flows of how many ports need to be counted is not fixed, so that a first statistics result corresponding to a data flow needs to be obtained through a receiving port statistics result handle list, which is referred to as a first handle list.
The data flow matching item in the matching table entry may include one or any combination of the following:
source MAC address, VLAN ID, ethernet class type.
In a specific implementation, the setting of the data stream matching item is not limited, and the relevant setting may be performed according to a specific application.
During specific implementation, the matching of the data stream matching item to the first statistical result corresponding to the data stream in the determined first handle list includes:
traversing the data stream in the first handle list;
for the data stream matched with all the matching items, acquiring a statistical result corresponding to the data stream;
and if the matching item with the matching value of the none exists, acquiring a first statistical result of the data stream matched with the matching items except the matching item corresponding to the none.
For each matching value corresponding to each data stream matching entry in the matching entries, if the matching value corresponding to one of the matching entries is: MAC address 1, VLAN1, the flow to be matched needs to meet the two conditions that the source MAC address is MAC address 1 and the VLAN ID is VLAN 1;
in a specific implementation, the matching value of the matching entry may also be set to none, and for example, the content corresponding to one of the matching entries is: if the source MAC address is MAC address 1 and the VLAN ID is none, the matched stream needs to satisfy the condition that the source MAC address is MAC address 1.
If the matching value corresponding to the none does not exist in the matching item, directly outputting a first statistical result corresponding to the matched data stream;
and if the matching value corresponding to the none exists in the matching items, when the first statistical result is obtained, obtaining the matching value corresponding to the matching item corresponding to the none in the first handle list, and when the first statistical result corresponding to the matched data stream is output, outputting the obtained matching value.
If the corresponding first statistical result is obtained for the MAC address 1 and the VLAN1, outputting: MAC address 1, VLAN1, first statistic result 1;
if the corresponding first statistical result is obtained for the MAC address 1 and the none (VLAN), if the MAC address 1 corresponds to the VLAN1 and the VLAN2, the output statistical result is:
MAC address 1, VLAN1, first statistic result 2;
MAC address 1, VLAN2, first statistic result 3.
The first statistical result comprises one or any combination of the following parameters:
l1 layer rate, number of received packets, frame rate, number of packet lost, packet loss percentage.
The statistical result is an example, and in the concrete implementation, the statistical result to be output can be set according to actual needs, and the statistical result can be expanded.
Obtaining the mark of the statistical result of whether the instrument is emptied after the statistical result is obtained:
the statistics of the meter is generally cleared in order to prevent the influence on the next statistical result after the first statistical result is obtained, but sometimes the statistics in the test process needs to be obtained, and the total packet loss statistics needs to be carried out for a long time or after abnormal tests, and the statistical result of the meter cannot be cleared at this time. Therefore, a parameter is needed to identify whether statistical information is emptied after statistics, and the statistical information needs to be cleared in general, so that the parameter is set as an optional parameter and the default value is clear. The concrete implementation is as follows:
if the processing flag set for the statistical result is clear, clearing the first handle list after the first statistical result is obtained; otherwise, the content in the first handle list is kept.
And when the corresponding data stream is not matched in the first handle list, assigning a specified value to the corresponding statistical result and outputting the specified value, so as to prevent errors caused by the fact that the statistical result of a certain expected data stream is not obtained.
And step 103, outputting the obtained first statistical result.
A specific example is given below to describe in detail a specific implementation of obtaining the first statistical result by the first function:
the first function: matching the data stream according to the field of the data stream to obtain a corresponding statistical result, and returning the field value of the field;
such as may be: STC _ classificationsisttics function.
Inputting parameters: lFilterName: matching table entries of the matching data stream, including the corresponding relation between the port identification and the matching entries;
dFilter: matching value of matching item, matching item (key) must contain value of hAna \
Examples are: { $ hAna-f1{ 10002: 00:00:00: 0101000015 } \\
$hAna-f2{200 02:00:00:00:00:02 0102 0016}\
$hAna-f3{300 02:00:00:00:00:01 0100 0015}}
If there is a none value in the value of the match value of dFilter, then this value is not used for matching but the value #is derived from the matching stream
lHAna: port analyzer handle
# lHAnaResult: receive statistics after port push analyzer matching
# ifClear: whether the empty classification statistic is 1 empty (default configuration) and 0 not empty
# return value: flag: "0" means no filter _ err. "1" indicates that there is filter _ err
Output parameter # output: dResult { $ hAna-f1{ frameCnt 30L1 BitRNAte 0getValue { { holdTime (hex) } { 000 f } } }
#$hAna-f2{frameCnt 10L1BitRate 0getValue{{holdTime(hex)}{002d}}}}
# where getValue is the matching value for the matching entry from the match result when the matching value in dFilter is none
The function call is: proc STC _ classificationsististiciscs function.
In the embodiment of the application, when the configured entry includes the port identifier, a first function is called to obtain a first statistical result from a first handle list on a test, and the first statistical result is output. In the embodiment of the application, the number of the searched data streams, the number of the matching items of a certain data stream and the value of the matching items are not limited, the returned data stream attribute can be added at will, and the method has strong universality, usability and transportability. The scheme can simply, conveniently and efficiently acquire the expected statistical result.
Example two
Referring to fig. 2, fig. 2 is a schematic view of a flow statistical result obtaining process in the second embodiment of the present application. The method comprises the following specific steps:
After the matching entry is obtained, the content included in the matching entry needs to be determined, and if it is determined that the matching entry includes the corresponding relationship between the port identifier and the data stream matching entry, step 202 is executed; if it is determined that the matching representation includes the data stream identification, step 204 is performed.
The first handle list is used for storing a statistical result of the port receiving data flow.
In an interface of a tester, analysis flow statistics results are port-based, a statistics result of each port can exist in one analyzer result handle, and the situation of receiving flows of how many ports need to be counted is not fixed, so that a first statistics result corresponding to a data flow needs to be obtained through a receiving port statistics result handle list, which is referred to as a first handle list.
The data flow matching item in the matching table entry may include one or any combination of the following:
source MAC address, VLAN ID, ethernet class type.
In a specific implementation, the setting of the data stream matching item is not limited, and the relevant setting may be performed according to a specific application.
During specific implementation, the matching of the data stream matching item to the first statistical result corresponding to the data stream in the determined first handle list includes:
traversing the data stream in the first handle list;
for the data stream matched with all the matching items, acquiring a statistical result corresponding to the data stream;
and if the matching item with the matching value of the none exists, acquiring a first statistical result of the data stream matched with the matching items except the matching item corresponding to the none.
For each matching value corresponding to each data stream matching entry in the matching entries, if the matching value corresponding to one of the matching entries is: MAC address 1, VLAN1, the flow to be matched needs to meet the two conditions that the source MAC address is MAC address 1 and the VLAN ID is VLAN 1;
in a specific implementation, the matching value of the matching entry may also be set to none, and for example, the content corresponding to one of the matching entries is: if the source MAC address is MAC address 1 and the VLAN ID is none, the matched stream needs to satisfy the condition that the source MAC address is MAC address 1.
If the matching value corresponding to the none does not exist in the matching item, directly outputting a first statistical result corresponding to the matched data stream;
and if the matching value corresponding to the none exists in the matching items, when the first statistical result is obtained, obtaining the matching value corresponding to the matching item corresponding to the none in the first handle list, and when the first statistical result corresponding to the matched data stream is output, outputting the obtained matching value.
If the corresponding first statistical result is obtained for the MAC address 1 and the VLAN1, outputting: MAC address 1, VLAN1, first statistic result 1;
if the corresponding first statistical result is obtained for the MAC address 1 and the none (VLAN), if the MAC address 1 corresponds to the VLAN1 and the VLAN2, the output statistical result is:
MAC address 1, VLAN1, first statistic result 2;
MAC address 1, VLAN2, first statistic result 3.
The first statistical result comprises one or any combination of the following parameters:
l1 layer rate, number of received packets, frame rate, number of packet lost, packet loss percentage.
The statistical result is an example, and in the concrete implementation, the statistical result to be output can be set according to actual needs, and the statistical result can be expanded.
Obtaining the mark of the statistical result of whether the instrument is emptied after the statistical result is obtained:
the statistics of the meter is generally cleared in order to prevent the influence on the next statistical result after the first statistical result is obtained, but sometimes the statistics in the test process needs to be obtained, and the total packet loss statistics needs to be carried out for a long time or after abnormal tests, and the statistical result of the meter cannot be cleared at this time. Therefore, a parameter is needed to identify whether statistical information is emptied after statistics, and the statistical information needs to be cleared in general, so that the parameter is set as an optional parameter and the default value is clear. The concrete implementation is as follows:
if the processing flag set for the statistical result is clear, clearing the first handle list after the first statistical result is obtained; otherwise, the content in the first handle list is kept.
And when the corresponding data stream is not matched in the first handle list, assigning a specified value to the corresponding statistical result and outputting the specified value, so as to prevent errors caused by the fact that the statistical result of a certain expected data stream is not obtained.
And step 203, outputting the obtained first statistical result. The flow is ended.
The second handle list is used for storing a corresponding second statistical result by taking the stream identifier as an index; and the third handle list is used for storing a third statistical result corresponding to the stream receiving by taking the stream identifier as an index.
Since the data stream is not able to count the sending information of the data stream according to the matching item in the tester interface, when we need the sending information of the data stream (such as sending rate, sending number, etc.) and do not care whether the specific field value of the received data stream meets our expectation, i need to obtain the flow statistic result according to the flow identifier, where the flow identifier may be a flow name or a flow ID.
When the corresponding data stream is not matched in the second handle list or the third handle list, assigning a specified value to the corresponding statistical result, and outputting the specified value; prevent errors caused by failure to obtain statistics of a certain expected data stream.
The second statistical result comprises one or a combination of the following parameters:
sending rate and sending number;
the second statistical result comprises one or any combination of the following parameters:
l1 layer rate, number of received packets, frame rate, number of packet lost, packet loss percentage.
The statistical result is an example, and in the concrete implementation, the statistical result to be output can be set according to actual needs, and the statistical result can be expanded.
Obtaining the mark of the statistical result of whether the instrument is emptied after the statistical result is obtained:
after the second statistical result or the third statistical result is obtained, statistics of the meter is generally cleared in order to prevent the influence on the next statistical result, but sometimes statistics in the test process need to be obtained, and total packet loss statistics needs to be carried out for a long time or after abnormal tests, and the statistical result of the meter cannot be cleared. Therefore, a parameter is needed to identify whether statistical information is emptied after statistics, and the statistical information needs to be cleared in general, so that the parameter is set as an optional parameter and the default value is clear. The concrete implementation is as follows:
if the processing flag set for the first statistical result is clear, clearing the first handle list after the first statistical result is obtained; otherwise, the content in the first handle list is kept.
If the processing flag set for the second statistical result is clear, clearing the second handle list after the second statistical result is obtained; otherwise, the content in the second handle list is kept.
If the processing flag set for the third statistical result is clear, clearing the third handle list after the third statistical result is obtained; otherwise, the content in the third handle list is kept.
And the set processing mark is used as an input parameter of the calling function, and after the calling function obtains the statistical result, the handle list is correspondingly processed according to the processing mark.
And when the corresponding data stream is not matched in the second handle list and the third handle list, assigning a specified value to the corresponding statistical result and outputting the specified value, so that errors caused by the fact that the statistical result of a certain expected data stream is not obtained are prevented.
And step 205, outputting the second statistical result and the third statistical result.
A specific example is given below to illustrate in detail the specific implementation of obtaining the second statistical result and the third statistical result on the tester through the second function:
function of the second function: obtaining a statistical result of the corresponding data stream according to the stream identification of the data stream;
# input parameters: lStreamName: matching list items of the data flow needing the statistical result, wherein the matching list items comprise flow identifications;
# resultDataSetTx: sending of data streams specifies statistical results txstreamresults
# resultDataSetRx: reception of a data stream specifies a statistical result rxstreamummaryresults
# return value: flag: "0" indicates that the acquisition was successful. "1" indicates acquisition failure
Output parameter # output: dResult { streamName1{ txFramecnt 1000rxFramecnt 1000l1BitRa 100frameRate \
10droppedFrameCount 0droppedFramePercent 0streamId 0}\streamName2{txFrameCnt 1000rxFrameCnt 1000l1BitRate 100frameRate 10\droppedFrameCount 0droppedFramePercent 0streamId 0}}
The function call is: proc STC _ detailedStreamStatiticalinformation function.
In the embodiment of the application, when the configured entry includes the port identifier, a first function is called to obtain a first statistical result from a first handle list on a test, and when the configured entry includes the stream identifier of the data stream, a second function is called to obtain a second statistical result and a third statistical result from a second handle list and a third handle list respectively, and the second statistical result and the third statistical result are output. In the embodiment of the application, the number of the searched data streams, the number of the matching items of a certain data stream and the value of the matching items are not limited, the returned data stream attribute can be added at will, and the method has strong universality, usability and transportability. The scheme can simply, conveniently and efficiently acquire the expected statistical result.
