In the present embodiment, first mode can be Hybrid untag patterns, and second mode can be Hybrid tag Pattern.Below using Hybrid untag patterns as first mode, as a example by Hybrid tag patterns are as second mode, to tested Being pre-configured with for equipment 110 is described in detail.

Control device 140 can be by being pre-configured with the test port and data-in port 111 of equipment under test 110 VLAN attributes are configuring the corresponding relation of each port of equipment under test 110 and VLAN.In the present embodiment, equipment under test 110 is made All of the port VLAN is added with Hybrid patterns, it is possible to understand that, it is port and phase that the port of equipment under test 110 adds VLAN The VLAN correspondences answered, for example, certain test port adds VLAN 2, and the as test port is corresponding for 2 VLAN with No. ID.

In the present embodiment, for make pattern of each port of equipment under test 110 to need add one or more specify VLAN, port number of the control device 140 according to the needs configuration of VLAN initial values VLAN_init and equipment under test 110 Port_num carries out calculating configuration to the VLAN attributes of multiple ports of equipment under test 110.The test lead of configuration equipment under test 110 The number of mouthful corresponding multiple VLAN for specifying is Port_num, specific VLAN ID can be from VLAN_init to VLAN_init+Port_num-1.In the present embodiment, the port of the needs configuration of the equipment under test 110 refers to equipment under test 110 Test port and equipment under test 110 data-in port 111.The VLAN initial values and the number of tested port Port_num is input into by user according to practical situation.

Multiple test ports are divided into into N groups and M groups, and the port of N groups and M groups is numbered respectively.Concrete numbering Mode can be, for the test port of N groups, number consecutively is N, N+1, N+2, by that analogy.For the test port of M groups, Number consecutively is M, M+1, M+2, by that analogy, as shown in Figure 2.

First, the untag values of each test port of N groups are configured, the untag values are a VLAN ID, represent phase The test port answered adds No. ID VLAN for specifying as untag values with Hybrid Untag patterns, and this No. ID is untag values The VLAN for specifying is corresponding target VLAN of corresponding test port.For each test port, its untag value only It is individual, and the untag values between each test port are different.

In the present embodiment, the corresponding untag values of each test port can be determined by the numbering of test port, is had Body, the untag values of configuration testing port are VLAN_init+ (Portid-N), and wherein Portid is the numbering of test port. For example, the port sum of equipment under test 110 is 2 for 6, VLAN initial values VLAN_init, for the test port that numbering is N+2, Its untag value is 2+N+2-N=4, that is, represent, the numbering of N groups is that the test port of N+2 is added with Hybrid Untag patterns VLAN 4, as shown in Figure 3.

Control device 140 is reconfigured at the tag values of each test port of the N groups of equipment under test 110, represent test port with Hybrid Tag patterns add No. ID VLAN for specifying for tag values.When port adds one with Hybrid Untag patterns After VLAN, it is impossible to add identical VLAN with Hybrid Tag patterns again.In the present embodiment, each test lead of N groups is configured The tag values of mouth have Port_num-1, in the respectively all of VLAN for specifying ID, weed out No. ID for after untag values Each value, represents each test port of N groups, and with untag patterns target VLAN is added, and adds what other were specified with tag patterns VLAN.Still with the port of equipment under test 110 sum be 6, VLAN initial values VLAN_init for as a example by 2, then it is multiple to specify No. ID of VLAN is respectively from 2 to 7, for the test port that numbering is N+2, because its untag value is 4, then and the test port With tag patterns add VLAN as No. ID for 2 to 3 and 5 to 75 VLAN for specifying.

Control device 140 is pre-configured with the untag values and tag values of the test port of the M groups of equipment under test 110.For M The configuration of the test port of group is similar with the test port configurations of N groups, the untag values of each test port of M groups and the survey of N groups The untag values of examination port are different, and the untag values between each test port of M groups are different.In the present embodiment, for M groups Each test port, still through its numbering determine untag values, can be VLAN_init+ (Portid-M)+(Port_ Num/2), the Portid represents the numbering of test port.Still the port sum with equipment under test 110 is as 6, VLAN initial values VLAN_init be 2 as a example by, for numbering be M+1 test port, its untag value be 2+ (M+1-M)+6/2=6, represent number Test port for M+1 adds VLAN 6 with Hybrid untag patterns, as shown in Figure 3.

Each test port of M groups, tag values are in all of VLAN for specifying ID, to weed out No. ID for untag values Each value afterwards.For example, when the port sum of equipment under test 110 is 2 for 6, VLAN initial values VLAN_init, numbering is M+1's The untag values of test port are 6, then its tag value is 2 to 5 and 7, represent the test port with the addition of Hybrid tag patterns VLAN be No. ID for 2 to 5 and 75 VLANs specified.As shown in Figure 3.

Also, control device 140 is pre-configured with the data-in port 111 of equipment under test 110 and adds one with untag patterns The individual VLAN for specifying, i.e. configuration data input port 111 a untag values, the untag of the data-in port 111 of configuration Untag value of the value equal to some test port in multiple test ports of equipment under test 110.In the present embodiment, configure The untag values of data-in port 111 are VLAN_init, equal to the untag values of the test port that numbering is N.

In addition, the described auxiliary survey port that control device 140 is pre-configured with the auxiliary measurement equipment 120 includes：The control dress The data receiver rule of each auxiliary survey port of 140 configurations is put, each auxiliary survey port only receives expiring for corresponding tested port transmission The test data of sufficient data receiver rule so that the test number that multiple test ports of the equipment under test 110 are issued every time When the test data of only one test port transmission meets data receiver rule according in, a corresponding auxiliary survey is only had Port receives.

The control device 140 configures two auxiliary survey ports of VLAN correspondences that each is specified in multiple assigned vlans.At this In embodiment, multiple VLAN for specifying of the configuration do not include corresponding target VLAN of the data-in port 111, i.e., by In the corresponding multiple VLAN for specifying of each test port of measurement equipment 110, except corresponding target VLAN of data-in port 111 Other each VLAN in addition, correspond to respectively two auxiliary survey ports, and the corresponding two auxiliary survey ports of the VLAN for specifying each can Data are forwarded with the VLAN specified by this.Specify different from other VLAN pair of the corresponding auxiliary survey ports of VLAN that each is specified The auxiliary survey port answered, in the present embodiment, should be different from referring to not exclusively equivalent, i.e., the VLAN that each is specified it is corresponding two it is auxiliary Survey corresponding with the VLAN that other the are specified two auxiliary survey ports in port and can have and intersect, but not exclusively as.

Control device 140 is also pre-configured with corresponding forwarding target VLAN in each auxiliary survey port of the auxiliary measurement equipment 120. The plurality of VLAN for specifying includes that described each auxiliary survey port is corresponding and forwards target VLAN, and each auxiliary survey port is corresponding Forwarding target VLAN is different from corresponding target VLAN of the data-in port 111, so that described each auxiliary survey port will The test data for meeting data receiver rule for receiving is set as forwarding the forwarding of target VLAN by the way that the auxiliary survey port is corresponding Data.

Specifically, control device 140 is by configuring the PVID attribute configurations of each auxiliary survey port of the auxiliary measurement equipment 120 Each auxiliary survey port of the auxiliary measurement equipment 120 is corresponding to forward target VLAN, the PVID values of each auxiliary survey port to be equal to The ID values of corresponding forwarding target VLAN in described each auxiliary survey port.

Likewise, control device 140 can be by configuring auxiliary survey port and the data-out port of auxiliary measurement equipment 120 121 VLAN (VLAN) attribute is configuring the corresponding relation of each port of auxiliary measurement equipment 120 and VLAN.

When configuring auxiliary measurement equipment 120, the port number Port_ of VLAN initial values VLAN_init and equipment under test 110 As when configuring equipment under test 110, multiple VLAN for specifying are No. ID from VLAN_init to VLAN_init+Port_ to num The Port_num VLAN of num-1.For each auxiliary survey port of auxiliary measurement equipment 120, its numbering is tested with corresponding connection As the numbering of the test port of equipment 110.That is, still the multiple auxiliary survey port of auxiliary measurement equipment 120 is divided into into N groups and M groups, N The numbering of auxiliary survey port of group is respectively N, N+1, N+2, and by that analogy, the auxiliary survey port number consecutively of M groups is M, M+1, M+2, By that analogy.The auxiliary survey port of correspondence connection is consistent with the numbering of tested port.

The PVID values of each auxiliary survey port are configured first.The PVID values of each auxiliary survey port are different, and each auxiliary survey port PVID values different from equipment under test 110 data-in port 111 untag values.In the present embodiment, can be according to every The numbering of individual auxiliary survey port determines its PVID value, for the auxiliary survey port of N groups, its PVID value be VLAN_init+ (Portid-N)+ 1, wherein Portid refers to port numbering.For example, when VLAN_init is 6 for 2, Port_num, then N group # is the auxiliary survey end of N+2 The PVID values of mouth are 2+ (N+2-N)+1=5, that is, represent, N group # is 5 for the PVID values of the auxiliary survey port of N+2, such as Fig. 3 institutes Show.

For the auxiliary survey port of M groups, its PVID value is VLAN_init+ (Portid-M)+(Port_num/2)+1.For example, when It is 6 that VLAN_init is 2, Port_num, then M group # is 2+ (M+1-M)+6/2+1=for the PVID values of the auxiliary survey port of M+1 7, as shown in Figure 3.

Control device 140 is also pre-configured with the tag values of the auxiliary survey port of auxiliary measurement equipment 120.Each auxiliary survey port has two Individual different tag values, two tag values of each auxiliary survey port are equal to two in No. ID of all of VLAN for specifying, and represent Auxiliary survey port adds No. ID two VLAN for specifying as corresponding two tag values with Hybrid Tag patterns.Also, each is auxiliary The one of tag values for surveying port are equal to the PVID values of the auxiliary survey port.In the present embodiment, the tag of the auxiliary survey port of configuration In value, the value equal with the untag values of the data-in port 111 of equipment under test 110 is not included, then, except No. ID equal to number According to other VLAN for specifying beyond the untag values of input port 111, two auxiliary survey ports of VLAN correspondences that each is specified.

In the present embodiment, two tag values of each auxiliary survey port of the N groups of auxiliary measurement equipment 120 are configured, one is equal to phase The PVID values of the auxiliary survey port answered, another is equal to VLAN_init+ (Portid-N)+(Port_num/2).Configure auxiliary measurement equipment Two tag values of each auxiliary survey port of 120 M groups, a PVID value for being equal to corresponding auxiliary survey port, another is equal to VLAN_init+(Portid-M)+1。

For example, when VLAN_init is 6 for 2, Port_num, then the tag values of the auxiliary survey port that numbering is N+2 are calculated, wherein One is equal to PVID values 5, and another is 2+N+2-N+6/2=7, that is, represent, the numbering of N groups is the port of N+2 with Hybrid Tag patterns add VLAN 5,7.For the tag values of the auxiliary survey port that numbering is M+1, one of them is equal to the auxiliary survey port PVID values 7, another is equal to 2+ (M+1-M)+1=4, that is, the numbering for representing M groups is that the port of M+1 is added with Hybrid Tag patterns Enter VLAN 7,4, as shown in Figure 3.

For the data-out port 121 of auxiliary measurement equipment 120, control device 140 is pre-configured with the auxiliary measurement equipment 120 The plurality of VLAN for specifying of the correspondence of data-out port 121.In the present embodiment, be pre-configured with data-out port 121 with What Hybrid Tag patterns addition No. ID Port_num from VLAN_init to VLAN_init+Port_num-1 was specified VLAN。

In addition, control device 140 is configured to the data receiver rule of the auxiliary survey port of auxiliary measurement equipment 120, the data It is an acl rule to receive regular, and the data receiver rule of all auxiliary survey port of the configuration of control device 140 is reception untag Data, abandon tag data so that only one in the test data that multiple test ports of the equipment under test are issued every time When the test data that test port sends is untag data, only have and transmission untag in the multiple auxiliary survey port of auxiliary measurement equipment The auxiliary survey port of the test port correspondence connection of data receives the untag data.

In the present embodiment, all of the port of auxiliary measurement equipment 120 with Hybrid Tag patterns add VLAN, do not have with Hybrid Untag patterns add any VLAN.

After the completion of control device 140 configures equipment under test 110 and auxiliary measurement equipment 120, can start to control tester 130 send test data to equipment under test 110 is tested.Fig. 4 is referred to, following steps are by matching somebody with somebody for providing in the present embodiment Put the concrete test process of equipment under test 110 is described in detail under mode.

Step S110：Control device 140 controls the data-in port of the tester 130 to the equipment under test 110 111 send test data.

In the present embodiment, the test data that tester 130 is sent to the input port of equipment under test 110 is made to be band VLAN The data of tag, the VLAN ID values in its VLAN tag are equal to the untag values of the data-in port 111 of equipment under test 110. In the present embodiment, the VLAN ID values in the VLAN tag of the test data that tester 130 sends are VLAN_init.Also, control Tester processed 130 to the transmission rate that equipment under test 110 sends test data is Speed_send, and the Speed_send is one Variable value, its initial value is equal to 1/ (Port_num-1) times of the port bandwidth Bandwidth of equipment under test 110, and unit is The initial value of bps, the Speed_send be equal to tester 130 to equipment under test 110 send test data transmission rate most Big value Speed_send_max.For example, when VLAN_init is 8 for 2, Port_num, the port bandwidth of equipment under test 110 is During 1000Mbps, then the VLAN tag of the test data that tester 130 sends to equipment under test 110 be 2, transmission rate it is initial Value size is 1000Mbps*1/ (8-1).

In addition, in the present embodiment, the byte length Packet_length of the test data that tester 130 sends by with Family sets according to practical situation, and 65 bytes, 128 bytes, 512 bytes, 1024 bytes, 1280 bytes, 1518 bytes etc. are can The byte length of choosing, naturally it is also possible to be other.

Step S120：The data-in port 111 of the equipment under test 110 receives the test data, and by institute State test data and the auxiliary measurement equipment 120 is sent to by all of test port.

Because all test ports of equipment under test 110 add the virtual local area specified that No. ID is VLAN_init Net, so data-in port 111 is received after the test data that VLAN tag are VLAN_init, by the test data flooding To all of test port.Again due to equipment under test 110 all test ports and auxiliary measurement equipment 120 a pair of auxiliary survey port 1 Should connect, each auxiliary survey port can be by transmission test data.

But, in the test port of equipment under test 110, the untag for only numbering the test port for being N is VLAN_ Init, represent test port that the numbering is N with Hybrid untag patterns add No. ID as VLAN_init specify it is virtual LAN, other test ports are No. ID virtual local areas specified as VLAN_init added with Hybrid tag patterns Net, then the numbering of the only N groups of equipment under test 110 be N test port send test data be untag data, other survey What examination port sent is tag data.Then, due to the data receiver rule of auxiliary measurement equipment 120, only equipment under test 110 Numbering is that the test data that the test port of N sends is received by the auxiliary survey port that the numbering of auxiliary measurement equipment 120 is N, auxiliary measurement equipment The test data that 120 other auxiliary survey ports receive can be dropped.

Step S130：One auxiliary survey port of the auxiliary measurement equipment 120 receives the test data, the survey that will be received Examination data return to the equipment under test 110 by the auxiliary survey port of another test data for not receiving forwarding, And the test data for receiving is sent to the tester 130 by the data-out port 121, the auxiliary survey sets Standby 120 receive the test data by a different auxiliary survey port every time.

The auxiliary survey port of auxiliary measurement equipment 120 is received after untag data, and the untag data are stamped into the auxiliary survey port PVID is simultaneously forwarded, it is possible to understand that, now, stamp auxiliary survey port PVID test data be tag data, its tag value It is equal to the PVID values of corresponding auxiliary survey port.Because the PVID values of the auxiliary survey port that numbering is N are VLAN_init+1, and it is auxiliary In the VLAN configurations of the port configuration of measurement equipment 120, the numbering of only M groups is auxiliary survey port and the data-out port 121 of M Just configuration add VLAN_init+1, then numbering be N auxiliary survey port by test data be forwarded to numbering be M auxiliary survey end Mouth and data-out port 121.

The test data for being forwarded to data-out port 121 is sent to the tester being connected with data-out port 121 130.It is forwarded to auxiliary survey port that numbering is M and connects test data is sent to the numbering is M auxiliary survey port is corresponding The test port of equipment under test 110.

Step S140：The equipment under test 110 receives the test data that the auxiliary measurement equipment 120 is returned, and by institute State test data to send to described again by other test ports in addition to the last port for receiving the test data Auxiliary measurement equipment 120, until each auxiliary survey port of the auxiliary measurement equipment 120 was received from described in the equipment under test 110 Test data.

Then, the numbering of equipment under test 110 is that to receive the tag values that auxiliary survey port sends be VLAN_ for the test port of M The test data of init+1.Because all test ports of equipment under test 110 add No. ID specifying for VLAN_init+1 VLAN, then numbering is that test data is flooded to other all test ports by the test port of M.And set due to tested In standby 110, the untag values for only numbering the test port for being N+1 are VLAN_init+1, and then, only numbering is the survey of N+1 The test data that examination port sends is untag data, is received by the auxiliary survey port that numbering in auxiliary measurement equipment 120 is N+1.

Numbering is that the auxiliary survey port of N+1 is received after untag data, is stamped the PVID of itself, because numbering is N+1 The PVID values of auxiliary survey port be VLAN_init+2, and in auxiliary survey port, except the auxiliary survey port that numbering is N+1, only Numbering is M+1 and the tag values of data-out port 121 are VLAN_init+2, then numbering is that the auxiliary survey port of N+1 will stamp Tag data forwardings after PVID to data-out port 121 and numbering be M+1 auxiliary survey port.

Data-out port 121 sends the test data for receiving to tester 130.Numbering is the auxiliary survey port of M+1 The test data for receiving is sent into the test port of the equipment under test 110 to correspondence connection.The test port of equipment under test 110 M+1 sends the test data again by other test ports in addition to the last port for receiving the test data To the auxiliary measurement equipment 120, the port that the test data is received for the last time is the test port that numbering is M+1.

Configured according to the port of equipment under test 110 and auxiliary measurement equipment 120, test data is according to above-mentioned data forwarding road Footpath forwards successively.The like, all test ports on equipment under test 110 all can be received once from auxiliary measurement equipment 120 The Tag test datas come and broadcast flooding is carried out in other all test ports in addition to itself of this equipment, and quilt Measurement equipment 110 is sent to every time in the test data of auxiliary measurement equipment 120, only one of which test port send for Untag data, its What his port sent is Tag data.This ensures that there the test number for being sent to auxiliary measurement equipment 120 from equipment under test 110 every time According in, the test data of only one of which port can actually enter auxiliary measurement equipment 120 and be flooded forwarding again, other test numbers According to being abandoned by acl rule.

And auxiliary measurement equipment 120 can all send out a to data-out port when forward to test data every time 121, being sent to tester 130 by data-out port 121 carries out the reception of test data.Due to the untag of each test port Value is different, then the test port for sending untag data every time is different, makes each test port be transmitted across being forwarded to tester 130 test data.

With VLAN initial values as shown in Figure 3 as 2, port sum is that 6 equipment under test 110 and auxiliary survey set to the present embodiment Standby 120 as specific embodiment being described in detail to the repeating process of test data.Fig. 5 shows that test data exists Trend between equipment under test 110 and auxiliary measurement equipment 120, wherein, the dotted line between equipment under test 110 and auxiliary measurement equipment 120 The data that expression does not meet the data receiver rule of auxiliary survey port and is dropped, between equipment under test 110 and auxiliary measurement equipment 120 Non- arrow line represents the annexation one by one between test port and auxiliary survey port.

The test data for receiving to be stamped and be forwarded to data-out port 121 after the PVID that numerical value is 5 by auxiliary survey port N+2 With the auxiliary survey port N that tag values include 5.The test data for receiving is sent to test port N, test port N by auxiliary survey port N Test data is flooded to into other test ports.The test data for receiving is sent to the auxiliary of correspondence connection by other test ports Port is surveyed, because the untag values for there was only test port M are 5, therefore the test data that only test port M sends is by auxiliary survey port M Receive, as shown in Figure 5.

The test data for receiving is stamped and the He of data-out port 121 is forwarded to after the PVID that numerical value is 6 by auxiliary survey port M Tag values include 6 auxiliary survey port N+1.The test data for receiving is sent to test port N+1, test lead by auxiliary survey port N+1 Test data is flooded to other test ports by mouth N+1.The test data for receiving is sent to correspondence and is connected by other test ports The auxiliary survey port for connecing, because the untag values for there was only test port M+1 are 6, therefore the test data that only test port M+1 sends Received by auxiliary survey port M+1, as shown in Figure 5.

The test data for receiving to be stamped and be forwarded to data-out port 121 after the PVID that numerical value is 7 by auxiliary survey port M+1 With the auxiliary survey port N+2 that tag values include 7.The test data for receiving is sent to test port N+2 by auxiliary survey port N+2, test Test data is flooded to other test ports by port N+2.The test data for receiving is sent to correspondence by other test ports The auxiliary survey port of connection, due to there is no the test port that untag values are 7, the test data is no longer received by auxiliary survey port, in It is no longer to forward.

Then, as shown in figure 5, the equipment under test 110 shown in Fig. 3 each test port floods test data to auxiliary measurement equipment When 120, the flow that only 1 test port sends can be received and forwarded again by auxiliary measurement equipment 120, other unnecessary surveys Examination data can be dropped.Also, each test data that tester 130 sends, can be by each of equipment under test 110 Test port sends once, is finally sent back to tester 130 by auxiliary measurement equipment 120.

Step S150：The tester 130 receives the test data that the auxiliary measurement equipment 120 sends.

Tester 130 receives each test data that the data-out port 121 of auxiliary measurement equipment 120 sends.

Step S160：Test data and the tester that the control device 140 sends according to the tester 130 130 test datas for receiving calculate the transfer capability of the equipment under test 110.

In the present embodiment, control device 140 can according to tester 130 send test data number, receive The number of test data, tester 130 send the byte length pair of the test data of the transmission rate and transmission of test data The transfer capability of equipment under test 110 is calculated.

Specifically, as shown in fig. 6, this step can include：

Step S161：After the presumptive test time, control device 140 judges the number of the test data that tester 130 is received The number of test port whether is equal to the business of the number of the test data for sending, if it is not, execution step S162, if so, performs Step S165.

When from tester 130 to equipment under test 110, transmission test data starts to presumptive test time Time_test, control Device processed 140 obtains number P acket_send of the test data that tester 130 sends to auxiliary measurement equipment 120 and from auxiliary survey Number P acket_receive of the test data that equipment 120 is received.With number P acket_ of the test data for receiving Receive judges the business that the obtains whether number phase with test port divided by number P acket_send of the test data for sending Deng.

The testing time can according to actual needs be set by user, also, can pass through intervalometer timing.Work as control device 140 control testers 130 start to equipment under test 110 send test data when, start intervalometer, when intervalometer timing it is long When degree reaches the default testing time, start to perform this step.
