As shown in fig. 1, the test system 100 of the communication device includes a server 101, a tester 120, and a communication device 103. The communication device 103 includes a first port1, a second port 2, and a third port 3, and the three ports of the communication device 130 are respectively connected to the tester 102. The server 101 may interact with the communication device 103 and the tester 102. For example, the server 101 may send control instructions to the tester 102 so that the tester 102 may send test samples to the communication device 103 according to the control instructions. For another example, the server 101 may also acquire a capacity value of the communication address table from the communication device 103.

In this embodiment, the communication device 103 needs to be configured before the communication device 103 is tested. For example, the server 101 communication device issues the configuration remotely, creates the VLAN200, and configures the first port1, the second port 2, and the third port 3 connected to the tester 102 to join the VLAN200 with ACCESS attributes. In addition, the server 101 may verify whether the configuration of the communication device 103 is correctly issued through a show/display command of the communication device 103. For example, the server 101 obtains the configuration information of the communication device 103, and then verifies whether the configuration information is the same as the expected result by adopting a regular expression matching mode, and if the configuration information is the same as the expected result, the configuration delivery is correct.

In some embodiments of the present invention, the server 101 described above may be used to provide services to the tester 102 and the communication device 103. The tester 102 may be configured to send a random communication source address and a random communication destination address to the communication device 103. The communication device 103 may be configured to receive a communication source address and a communication destination address sent by the tester 102, learn the communication source address, and forward data through a port of the communication device 103 according to the communication destination address. In the present embodiment, the communication device 103 may be an interactive machine, a router, or the like, but is not limited thereto.

In some embodiments of the present invention, the tester 102 receives a control instruction sent by the server 101, and sends a test sample to the first port1 of the communication device 103 according to the control instruction, where the test sample includes s communication source addresses, and s is greater than zero; the communication equipment 103 receives the test sample, learns the communication source address in the test sample, and records the learned communication source address in the communication address table; the server 101 acquires a capacity value n of a communication address table from the communication device 103, wherein n is greater than zero; the server 101 updates the number of the communication source addresses until the capacity value of the communication address table and the number of the communication source addresses meet a first preset condition; the server 101 acquires the packet receiving rate of the third port 3 from the communication device 103; the server 101 updates the number of the communication source addresses until the packet receiving rate of the third port 3 meets a second preset condition.

In an embodiment of the present invention, the test sample may include s communication source addresses. Wherein s is greater than zero. The initial value of s in this embodiment may be set according to actual circumstances. For example, the number of communication source addresses, i.e., the initial s is set according to the chip capacity in the communication device. Assuming that the chip capacity in the communication device is m, the number of communication source addresses may be set to 2m, i.e., s is 2m, according to the chip capacity in the communication device.

In an embodiment of the present invention, the communication source address may be a MAC source address, an ARP source address, a routing source address, or the like, but is not limited thereto.

In one embodiment of the present invention, after the communication device receives the test sample, the communication device may learn a communication source address in the test sample, and record the learned communication source address in the communication address table. The server can acquire the capacity value n of the communication address table from the communication equipment in real time, and the acquisition is stopped when the capacity value n of the communication address table is not changed any more. N in this embodiment may refer to the number of communication source addresses included in the communication address.

In one embodiment of the invention, the number of the communication source addresses is updated until the capacity value of the communication address table and the number of the communication source addresses meet a first preset condition. Wherein the first preset condition may be that n ═ s or n ═ s, and 1-abs (pre _ n/n-1) ≧ 99.9%. In the present embodiment, when n is s, the number of communication source addresses is stopped from being updated, that is, s is stopped from being updated. Or when n is equal to s and 1-abs (pre _ n/n-1) is equal to or more than 99.9%, the updating of the number of the communication source addresses is stopped, that is, the updating of s is stopped. And pre _ n is the capacity value n of the communication address table in the communication equipment obtained by the last test in the whole circulation test flow. Generally, the initial value of pre _ n is set to 0.

In an embodiment of the present invention, the packet receiving rate of the third port may refer to a forwarding rate of forwarding data through the third port of the communication device. If the data is not forwarded through the third port of the communication device, the packet receiving rate of the third port is set to zero.

In an embodiment of the present invention, the number of the communication source addresses is updated until the packet receiving rate of the third port satisfies a second preset condition. Wherein the second preset condition is that TC3_ Rx _ Rate is 0, or TC3_ Rx _ Rate is 0, and 1-abs (pre _ s/s-1) ≧ 99.9%. And the TC3_ Rx _ Rate is a packet receiving Rate of the third port, pre _ s verifies the number of the communication destination addresses in the sample for the last test in the whole cyclic test flow, and when the capacity value of the communication address table and the number of the communication source addresses meet a first preset condition, pre _ s is equal to n. Generally, the initial value of pre _ s is set to 0. In the present embodiment, when TC3_ Rx _ Rate is 0, the number of communication source addresses stops being updated, that is, the update s is stopped. Alternatively, when TC3_ Rx _ Rate is 0 and 1-abs (pre _ s/s-1) ≧ 99.9%, the number of communication source addresses is stopped from being updated, i.e., s is stopped from being updated.

The method can use the communication source address in the communication address table as the communication destination address in the verification sample, which helps the communication device forward the data in the verification sample through the first port and/or the third port according to the n communication destination addresses in the verification sample so as to obtain the packet receiving rate of the third port.

In an embodiment of the present invention, the communication address table is used for storing a communication source address and a port identifier, and is specifically shown in table 1:

TABLE 1

Communication source address	Port identification
		MAC Source Address A	Port1
MAC Source Address B	Port1
		MAC Source Address C	Port1

Alternatively, in step S430, if the capacity value of the communication address table and the number of the communication source addresses satisfy the first preset condition, the number of the communication destination addresses in the verification sample is set to n.

The method can judge whether the capacity value of the communication address table and the number of the communication source addresses meet a first preset condition or not, and trigger an updating mechanism if the capacity value of the communication address table and the number of the communication source addresses do not meet the first preset condition. Or if the capacity value of the communication address table and the number of the communication source addresses meet the first preset condition, setting the number of the communication destination addresses in the verification sample as n, and in this way, rapidly and accurately triggering an updating mechanism or setting the number of the communication destination addresses in the verification sample as n.

In an embodiment of the present invention, if the capacity value of the communication address table and the number of the communication source addresses do not satisfy the first preset condition, an update mechanism is triggered. For example, if n is smaller than s, an updating mechanism is triggered, and an updating step is executed, namely the number of the communication source addresses is updated until the capacity value of the communication address table and the number of the communication source addresses meet a first preset condition. For another example, if n is equal to s and 1-abs (pre _ n/n-1) < 99.9%, an updating mechanism is triggered, and an updating step is executed, i.e., the number of the communication source addresses is updated until the capacity value of the communication address table and the number of the communication source addresses meet the first preset condition. In the present embodiment, 99.9% is the preset test accuracy. The test precision can be adjusted according to actual requirements.

Fig. 5 schematically shows a flow chart of a method of testing a communication device according to another embodiment of the invention.

As shown in fig. 5, the step S230 may specifically include steps S510 to S550.

In step S510, the number of communication source addresses is updated by using a dichotomy.

In step S520, the communication source address in the communication address table in the communication apparatus is deleted.

In step S530, the updated number of communication source addresses is sent to the tester, and the tester is controlled to send the communication source addresses to the communication device with the updated number of communication source addresses.

In step S540, a capacity value n of the communication address table is acquired from the communication apparatus.

In step S550, the steps S510 to S540 are repeated until the capacity value of the communication address table and the number of the communication source addresses satisfy a first preset condition.

The method can update the number of the communication source addresses by circulating the steps S510 to S540 until the capacity value of the communication address table and the number of the communication source addresses meet the first preset condition, so that the capacity value of the communication address table and the number of the communication source addresses can quickly meet the first preset condition, and the test efficiency is improved.

In one embodiment of the invention, the number of the communication source addresses is updated by adopting a dichotomy method, so that the performance specification precision of the communication equipment can be controlled within a desired value. For example, the number of communication source addresses is updated based on the minimum value min _ s of the number of communication source addresses and/or the maximum value max _ s of the number of communication source addresses. In this embodiment, the initial value of min _ s is 0, the initial value of max _ s is 2m, and the initial value of s is 2 m.

Specifically, when n < s, update s is (min _ s + s)/2, where min _ s is the updated min _ s when the last test fails to satisfy the first preset condition (n is s, and 1-abs (pre _ n/n-1) < 99.9%). In addition, when n < s, max _ s also needs to be updated to the current s.

When n is equal to s and 1-abs (pre _ n/n-1) < 99.9%, update s is equal to (max _ s + s)/2, where max _ s is the updated max _ s when the last test fails to satisfy the first preset condition (n < s). In addition, when n ═ s and 1-abs (pre _ n/n-1) < 99.9%, min _ s also needs to be updated to the current s.

In one embodiment of the present invention, when the capacity value of the communication address table and the number of the communication source addresses satisfy the first preset condition, the flag is set to 1, and the above pre _ s is set to the capacity value of the current communication address table, that is, to the current n. On the contrary, when the capacity value of the communication address table and the number of the communication source addresses do not satisfy the first preset condition, the flag is set to 0, and the above pre _ n is set to the capacity value of the current communication address table, that is, to the current n. In this embodiment, flag is 1, which indicates that the capacity value of the communication address table and the number of communication source addresses satisfy the first preset condition. And when the flag is 0, the capacity value of the communication address table and the number of the communication source addresses do not meet the first preset condition.

Fig. 6 schematically shows a flow chart of a method of testing a communication device according to another embodiment of the invention.

As shown in fig. 6, after the step 240, the method further includes a step S610 to a step S630.

In step S610, it is determined whether the packet receiving rate of the third port satisfies the second preset condition.

In step S620, if the packet receiving rate of the third port does not satisfy the second preset condition, an update mechanism is triggered. Or, in step S630, if the packet receiving rate of the third port meets the second preset condition, the number of the current communication source addresses is recorded.

The method can judge whether the packet receiving rate of the third port meets a second preset condition, and if the packet receiving rate of the third port does not meet the second preset condition, an updating mechanism is triggered. Or, if the packet receiving rate of the third port meets the second preset condition, the number of the current communication source addresses is recorded, and in this way, the updating mechanism can be triggered quickly and accurately or the number of the current communication source addresses is recorded.

In an embodiment of the present invention, if the packet receiving rate of the third port does not satisfy the second predetermined condition, the update mechanism is triggered. For example, if the TC3_ Rx _ Rate > 0, the updating mechanism is triggered to perform the updating step, i.e. updating the number of the communication source addresses, until the packet receiving Rate of the third port meets the second preset condition. For another example, if the TC3_ Rx _ Rate is 0 and 1-abs (pre _ s/s-1) < 99.9%, the updating mechanism is triggered to perform the updating step, i.e., update the number of the communication source addresses until the packet receiving Rate of the third port meets the second preset condition. In the present embodiment, 99.9% is the preset test accuracy. The test precision can be adjusted according to actual requirements.

In one embodiment of the present invention, when TC3_ Rx _ Rate is 0 and 1-abs (pre _ s/s-1 ≧ 99.9%, the number of current communication source addresses may be regarded as infinitely approaching the true performance of the communication apparatus, in which case the number of current communication source addresses may be regarded as the number of communication source addresses that the communication apparatus can maximally tolerate.

Fig. 7 schematically shows a flow chart of a method of testing a communication device according to another embodiment of the invention.

As shown in fig. 7, the step S250 may specifically include steps S710 to S780.

In step S710, the number of communication source addresses is updated by using a dichotomy.

In step S720, the communication source address in the communication address table in the communication apparatus is deleted.

In step S730, the updated number of communication source addresses is sent to the tester, and the tester is controlled to send the communication source addresses to the communication device with the updated number of communication source addresses.

In step S740, a capacity value n of the communication address table is acquired from the communication apparatus.

In step S750, it is determined whether the capacity value of the communication address table and the number of the communication source addresses satisfy a first preset condition, and if the capacity value of the communication address table and the number of the communication source addresses satisfy the first preset condition, the number of the communication destination addresses in the verification sample is set to be n.

In step S760, the tester is controlled to send the verification sample to the second port of the communication device, so that the communication device forwards the data in the verification sample through the first port and/or the third port according to the n communication destination addresses in the verification sample.

In step S770, a packet receiving rate of the third port is obtained from the communication device.

In step S780, the steps S710 to S770 are repeated until the packet receiving rate of the third port satisfies the second preset condition.

The method can update the number of the communication source addresses by circulating the steps S710 to S770 until the packet receiving rate of the third port meets the second preset condition, so that the packet receiving rate of the third port can quickly meet the second preset condition, and the test efficiency is improved.

In one embodiment of the invention, the number of the communication source addresses is updated by adopting a dichotomy method, so that the performance specification precision of the communication equipment can be controlled within a desired value. For example, the number of communication source addresses is updated based on the minimum value min _ s of the number of communication source addresses and/or the maximum value max _ s of the number of communication source addresses. In this embodiment, the initial value of min _ s is 0, the initial value of max _ s is 2m, and the initial value of s is 2 m.

Specifically, when TC3_ Rx _ Rate > 0, update s is (min _ s + s)/2, where min _ s is min _ s updated when the last test fails to satisfy the second preset condition (TC3_ Rx _ Rate is 0, and 1-abs (pre _ s/s-1) < 99.9%). In addition, when TC3_ Rx _ Rate > 0, max _ s also needs to be updated to the current s.

When TC3_ Rx _ Rate is 0 and 1-abs (pre _ s/s-1) < 99.9%, update s is (max _ s + s)/2, where max _ s is the updated max _ s when the last test fails to satisfy the second preset condition (TC3_ Rx _ Rate > 0). In addition, when TC3_ Rx _ Rate is 0 and 1-abs (pre _ s/s-1) < 99.9%, min _ s also needs to be updated to the current s.

The test method of the communication equipment provided by the invention can be used for testing a large number of performance values (namely the number of communication source addresses) of the communication equipment, so that the efficiency can be improved, the test result is infinitely close to the real performance of the communication equipment, the test precision meeting the requirement is set, and the test precision is further improved. For example, the number of the communication source addresses can be updated quickly through the loop flow described in the embodiment of fig. 5 or the loop flow described in the embodiment of fig. 7, which is helpful for improving efficiency, so that the test result infinitely approaches to the real performance of the communication device, and the test precision meeting the requirement is set, thereby further improving the test precision.
