Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The following are detailed descriptions of the respective embodiments.
Example one
The embodiment of the invention provides a test method, a processing flow chart of which is shown in figure 1, and the test method comprises the following steps:
step S101, the tester sends test flow to the equipment to be tested, and the test flow comprises the flow to be tested and background flow.
The tester can be selected from common testers such as TC (Testcenter), Smartbits, IXIA, Xin and Tai (XINNERTEL) or streaming software.
It should be noted that before the tester sends the test traffic to the device to be tested, a specified number of traffic to be tested needs to be created on the tester, where the traffic to be tested includes different IP addresses and port numbers, the protocol types of the traffic to be tested are not limited, and the protocol types of all messages in the traffic to be tested are the same. The flow to be detected can adopt UDP messages, TCP messages or other protocol type messages. Meanwhile, background flow is established on the tester, and at least one tuple in the quintuple of the background flow and the quintuple of the flow to be tested is different; the flow to be detected and the background flow are distinguished by the identifier in the message reserved field.
For example, traffic to be tested including N different IP addresses and M different port numbers is created, which is NXM types of traffic to be tested, and the message type of the traffic to be tested may be UDP message, TCP message, or other protocol types. And meanwhile, background flow is created, the number of the messages contained in the background flow is not limited, and at least one tuple of any message in the background flow is different from at least one tuple of each message in the flow to be detected. The flow to be detected and the background flow can be distinguished by the identifier in the message reserved field. For example, the message reserved field is set with special characters, character strings or Bit bits for distinguishing.
For example, in the embodiment of the present invention, an IP Reserved field in a message is set as an example to distinguish traffic to be detected from background traffic, where the IP Reserved field is a first Bit located in an IP header Flag field, and a default value of the IP Reserved field is 0. For example, the traffic to be measured may be indicated when the IP Reserved field is set to 1, and the background traffic may be indicated when the IP Reserved field is set to 0.
And S102, the device to be tested performs NAT (network Address translation) conversion on the flow to be tested according to a preset conversion rule, and sends the background flow and the flow to be tested which is subjected to the NAT conversion to the flow analysis device.
In this embodiment, the device under test may be a router, a firewall, or other devices supporting NAT function. The preset conversion rule can be matched according to the quintuple of the flow to be detected. Under normal conditions, the device to be tested only performs NAT conversion on the traffic to be tested, sends the traffic to be tested after NAT conversion to the traffic analysis device, and simultaneously directly forwards the background traffic to the traffic analysis device. This step is a standard function and a using method of the NAT technology, and is not described herein again.
It should be noted that the device to be tested may send the test traffic to the traffic analysis device in a routing manner, a mirror traffic manner, or the like.
Step S103, the flow analysis equipment counts the flow with the correct NAT conversion so as to be used for a tester to analyze the result.
In this embodiment, the traffic analysis device may be a server, a PC, a traffic analyzer, or the like, in which a message analysis program is installed. In this step, the traffic analysis device stores the received messages in a local storage space, and then analyzes the stored messages one by one, and extracts key fields such as an IP Reserved field, a source IP address, a destination IP address, a protocol type, a source port number, a destination port number, and the like in the messages. One implementation is that the traffic analysis device performs statistics on the traffic correctly translated by the NAT by comparing key fields in the message.
In this embodiment, the traffic analysis device determines that, if the identifier of the reserved field in the message of the received traffic is the same as the identifier of the reserved field in the traffic to be detected, the IP address range in the message belongs to the translation address pool range, and the protocol type of the message is the same as the protocol type of the traffic to be detected, the message belongs to the traffic with correct NAT translation, and may generate the unique identifier of the traffic type corresponding to the message, where the unique identifier of the traffic type may be obtained by a five-tuple or seven-tuple calculation MD5 value of the message, or may be obtained in a user-defined manner. In another embodiment of the present invention, the unique identifier of the traffic type is illustrated by using an MD5 value as an example, and the MD5 value may be obtained by calculating the identifier of a Reserved field in the five-tuple and IP Reserved fields of the packet. If the unique identifier of the traffic type corresponding to the message is different from the unique identifiers of the traffic types corresponding to the other received messages, the traffic type to which the message belongs is a brand new traffic type on the traffic analysis equipment, and the traffic analysis equipment stores the unique identifier of the traffic type corresponding to the message and accumulates a correct statistical value. If the unique identifier of the traffic type corresponding to the message is the same as the unique identifier of the traffic type corresponding to the received message, it is indicated that the traffic type to which the message belongs has already been counted on the traffic analysis device, and at this time, the correct counting value remains unchanged. Wherein the initial value of the correct statistic is 0.
In the embodiment of the invention, after waiting for the preset time, the tester stops streaming. The device to be tested counts the number of the generated NAT table entries, so that a tester can judge whether the number of the NAT table entries is equal to that of the NAT table entries according to the number of the NAT table entries, a correct statistical value and a specified number when the flow to be tested is created, and if the number of the NAT table entries is equal to that of the NAT table entries, a test result meets a test requirement; otherwise, the test result is not in accordance with the test requirement.
For example, in step S101, NXM types of traffic to be tested are included in the traffic to be tested created on the tester. The number of the generated NAT table entries can be checked in real time by adopting a command on the device to be tested, and the number of the NAT table entries is assumed to be Count. The correct statistic can be checked on the flow analysis equipment in a real-time display mode, and the correct statistic is assumed to be TestNum. After waiting for a preset time, the tester stops streaming, if Count is NXM, it indicates that the number of the NAT table entries generated by the device to be tested is the same as the number of the flows to be tested created on the tester, and the generated NAT table entries have no repeated entries, and at the same time, the device to be tested performs correct conversion on all the flows to be tested according to the NAT table entries, which indicates that the test result meets the preset test requirement, and the NAT function of the device to be tested is normal; otherwise, the NAT function of the device to be tested is abnormal.
For example, if the Count is not equal to NXM, it indicates that the device under test does not generate the corresponding number of NAT entries, and the reason for this phenomenon may be caused by insufficient NAT conversion performance of the device under test or due to an abnormal NAT function of the device under test. If TestNum is not equal to NXM, it indicates that the device under test has not performed correct NAT translation for all traffic under test. One of the reasons for this phenomenon may be that the device under test does not perform NAT conversion on part of the traffic to be tested due to insufficient NAT conversion performance of the device under test, and at this time, Count is not equal to NXM and TestNum is not equal to NXM. Another reason for this phenomenon may be caused by an abnormal NAT function of the device to be tested, for example, the NAT function of the device to be tested incorrectly converts different multiple traffic messages to be tested into the same message, where Count is equal to NXM and TestNum is not equal to NXM.
Another possible implementation manner is that the traffic analysis device performs statistics on traffic with correct NAT translation and also performs statistics on traffic with incorrect NAT translation. The traffic analysis device performs statistics on the traffic of the NAT conversion error, and the statistics includes: and judging that the message belongs to the flow of NAT conversion errors and accumulating error statistics if the identification of the reserved field in the message of the received flow is the same as the identification of the reserved field in the background flow and the IP address range in the message belongs to the range of the conversion address pool. And if the error statistic value is not equal to the initial value, the testing result does not meet the preset testing requirement, and the NAT function of the equipment to be tested is abnormal. At the moment, the tester can stop the flow of the tester in time, so that the testing time is saved. Wherein the initial value of the error statistic is 0.
For example, if the traffic analysis device performs statistics on the traffic with the NAT translation error, the error statistics value can be viewed on the traffic analysis device in a real-time display manner. If the error statistic value is BgNum, if the BgNum is not equal to the initial value, the background traffic is converted when the NAT function of the equipment to be tested is wrong, and the NAT function of the equipment to be tested is abnormal. At the moment, the tester can stop the flow of the tester in time so as to save the testing time.
Preferably, after the traffic analysis device counts the traffic correctly converted by the NAT, the traffic analysis device determines that if the correct statistical value does not change any more within a specified time period, the traffic analysis device sends the correct statistical value to the controller; and after receiving the correct statistical value, the controller obtains a test result according to the acquired specified quantity of the flow to be tested and the quantity of the NAT table entries. The determination method is the same as above, and is not described herein again.
Another possible implementation manner is that after the traffic analysis device performs statistics on the traffic of the NAT conversion error, if the error statistic value is not equal to the initial value, the traffic analysis device sends the error statistic value to the controller, and the controller obtains that the test result does not meet the preset test requirement and notifies the tester to stop streaming, so as to save the test time.
The internal calculation time of the embodiment of the invention is very short, and the test result can be displayed in real time or automatically. The method can ensure the accuracy and the rigor of the test result, can greatly improve the test efficiency of testers, and saves the investment of a large number of test resources. Especially, the value of the invention can be fully embodied when the number of the generated NAT table entries is more.

Wherein the initial value of the correct statistic is 0.
In this embodiment, a tester judges whether the NAT entries are equal to each other according to the number of the NAT entries, the correct statistical value, and the specified number when creating the traffic to be tested, and if the NAT entries are equal to each other, it indicates that the test result meets the test requirement; otherwise, the test result is not in accordance with the test requirement.

If the error statistic is not equal to the initial value, it indicates that the test result does not meet the preset test requirement, and the NAT function of the device under test 202 is abnormal.
