Referring to fig. 1, fig. 1 is a flowchart of a message processing method according to an embodiment of the present application, where the method may include the following steps:
s101: and the test board card in the tester generates a test message according to the test information and sends the test message to the expansion board card in the tester through the test port of the test board card.
In the application embodiment, at least one test board card and at least one expansion board card can be configured in the tester, one test board card can be provided with at least one test port, and the test board card can be connected with the expansion board card through the test port, wherein the connection form of the expansion board card and the test board card can be various, generally speaking, one expansion board card can be connected with one test port of one test board card, so that one test port can simultaneously test a plurality of devices to be tested, in addition, one expansion board card can also be connected with a plurality of test ports of one test board card according to actual requirements, and one expansion board card can also be connected with a plurality of test ports of a plurality of test board cards.
The test information may be issued by a manager of the tester, and the test information is used to indicate a test packet to be generated, for example, the test information may include information such as a protocol type of the test packet to be generated, a packet length of the test packet, and a flag bit in the test packet. The test board card can acquire test information issued by a manager and store the test information in the local.
When a test message needs to be generated, the test board card can acquire locally stored test information, and then generate a corresponding test message based on the test information and send the test message to the test port of the test board card, and correspondingly, the expansion board card connected with the test port can receive the test message.
S102: and the expansion board card respectively sends the copied test messages to the equipment to be tested connected with the expansion port of the expansion board card according to the stored flow table.
The flow table may be used to instruct the expansion board to compare and forward the test packet.
In one implementation, an administrator may issue a flow table to an expansion board through a controller of a control plane in an SDN (Software Defined Network), and the expansion board may store the received flow table locally.
Correspondingly, after the expansion board card receives the test message sent by the test board card, the received test message can be copied based on the stored flow table to obtain a plurality of test messages, and then the expansion board card can respectively send the plurality of test messages obtained by copying to the own expansion port, and correspondingly, the device to be tested connected with the expansion port can receive the test message.
It can be seen that, based on the message processing method provided in the embodiment of the present application, for a test message generated by a test board, an extension board in a tester can copy the test message according to a flow table to obtain a plurality of test messages, and send the test messages to corresponding extension ports respectively, so as to test a plurality of devices to be tested, that is, a plurality of devices to be tested can be tested through one test port, and the performance of providing test services by the tester can be improved without adding a test board, so that the cost of the tester can be reduced.
Optionally, the expansion board card may copy the test packet in different manners according to the service requirement.
In one approach, S102 may include the following steps:
the method comprises the following steps of firstly, copying N parts of test messages, and respectively distributing marks for the N parts of copied test messages according to expansion ports of an expansion board card.
Wherein, N is the number of the expansion ports, the labels of the N copied test messages are different from each other, and each label corresponds to one expansion port.
In the application embodiment, after receiving the test packets sent by the test board, the expansion board may test the received test packets based on the number N of the expansion ports to obtain N test packets.
Then, the expansion board card can distribute the marks to the N test messages respectively based on the expansion ports of the expansion board card, so that the N marked test messages respectively correspond to the N expansion ports one to one.
For example, the expansion board may allocate port identifiers of N expansion ports to N test packets, respectively.
Alternatively, different flow table numbers may be set in advance for the flow tables corresponding to the N expansion ports, and the N flow table numbers may be assigned to the N test packets as corresponding tags.
And step two, aiming at each copied test message, searching a corresponding flow table according to the allocated mark.
In the application embodiment, after distributing the markers for the N packets, for each test packet with the distributed markers, the expansion board may determine a flow table corresponding to the marker distributed for the test packet, so as to process the test packet according to the corresponding flow table.
Step three, if the characteristic information of the copied test message is matched with the flow table, the copied test message is sent to the device to be tested connected with the expansion port of the expansion board card through the corresponding expansion port; otherwise, the copied test message is discarded.
In the application embodiment, after determining the flow table corresponding to each test packet to which the label is assigned, the expansion board card may obtain the feature information recorded in the flow table, and compare the feature information with the feature information of the test packet.
The characteristic information may include at least one of the following information: protocol type of the message, source IP address of the message, source MAC (Media Access Control) address of the message, and the like.
If the feature information of the test packet matches the feature information recorded in the corresponding flow table, the expansion board card may send the test packet to the corresponding expansion port, and correspondingly, the device to be tested connected to the expansion port may receive the test packet.
In one mode, a corresponding expansion port may be recorded in the flow table, and after determining that the feature information of the test packet matches the feature information recorded in the corresponding flow table, the expansion board card may determine the expansion port recorded in the corresponding flow table and send the test packet to the determined expansion port.
It can be understood that, before sending the test packet, the expansion board card may also modify the test packet according to a processing manner recorded in the corresponding flow table, where the processing manner may include modifying a protocol type of the test packet and/or modifying a packet structure of the test packet.
For example, if the test packet is a UDP (User Data Protocol) packet and the processing manner recorded in the flow table is to modify the test packet into a TCP (Transmission Control Protocol) type, the extension board may modify the test packet into a TCP packet.
For another example, if the test packet includes an a field and the processing manner of the record in the flow table is to modify the a field of the packet into a B field, the expansion board may modify the a field in the test packet into a B field.
If the feature information of the test packet is not matched with the feature information recorded in the corresponding flow table, it indicates that the device to be tested connected with the corresponding expansion port does not need the test packet, and correspondingly, the expansion board card may discard the test packet.
In another manner, S102 may include the steps of:
step 1, obtaining flow tables stored in the expansion board card, sequentially comparing the characteristic information of the test message for each flow table, and determining whether the flow tables are matched with the flow tables.
In the embodiment of the application, in order to reduce the load of the CPU of the expansion board card, the expansion board card may not directly copy the test packet.
After receiving the test message sent by the test board, the expansion board can acquire the locally stored flow tables, and then the expansion board can compare each flow table with the test message in sequence and perform corresponding processing according to the comparison result.
Step 2, if the characteristic information of the test message is matched with the stored flow table, copying the test message according to the flow table, and sending the copied test message to the device to be tested connected with the expansion port of the expansion board card through the corresponding expansion port based on the mark in the flow table; otherwise, comparing the feature information of the test message with the next flow table.
In the application embodiment, for one flow table, if the expansion board determines that the feature information recorded in the flow table matches with the feature information of the test packet, the expansion board may send the test packet to the corresponding expansion port.
If the expansion board card judges that the feature information recorded in the flow table is not matched with the feature information of the test message, it indicates that the device to be tested connected with the expansion port corresponding to the flow table does not need the test message, and then the expansion board card can continue to compare the feature information of the test message with the feature information recorded in the next flow table, and so on until the expansion board card compares the feature information recorded in all the flow tables with the feature information of the test message.
It can be understood that, if the expansion board card determines that the feature information recorded in the flow table matches with the feature information of the test packet, after sending the test packet to the corresponding expansion port, the expansion board card may also compare the feature information of the test packet with the next flow table.
In the above process, the expansion board card may set different flow table numbers for each flow table, and sequentially compare the feature information recorded in each flow table with the feature information of the test packet according to the flow table coding sequence.
Or, the expansion board card may also randomly select one flow table from the current flow tables that are not compared for comparison, after the comparison is finished, it may mark that the flow table is compared, and then select one flow table from the remaining flow tables that are not compared for comparison, and so on.
Optionally, the method may further include the steps of: and the test board card in the tester generates a flow table according to the configuration information and issues the flow table to the expansion board card.
The configuration information is used for indicating the test board card to generate a corresponding flow table.
In the application embodiment, the administrator may also directly issue configuration information for generating the flow table to the test board, and correspondingly, the test board may generate a corresponding flow table based on the configuration information and send the generated flow table to the expansion board, and the expansion board may receive the flow table sent by the test board and store the flow table locally, so as to copy and forward the test packet generated by the test board according to the flow table.
Referring to fig. 2, fig. 2 is a flowchart of an overall scheme of a message processing method according to an embodiment of the present application.
In fig. 2, a test board card in the tester may be provided with a test packet generation module, and the test packet generation module may generate a corresponding test packet according to the test information and send the generated test packet to the test port.
The test board card can also generate 3 flow tables according to the configuration information issued by the administrator, the expansion port recorded in the flow table 1 is the expansion port 1, the expansion port recorded in the flow table 2 is the expansion port 2, the expansion port recorded in the flow table 3 is the expansion port 3, and the generated flow tables are sent to the expansion board card.
The message copying module in the expansion board card connected to the test port may copy the test message sent by the test board card according to the number of current Openflow (a network communication protocol, which belongs to a data link layer and can control a forwarding plane of an on-line switch or a router). The number of Openflow instances is the number of expansion ports. In the embodiment of the present application, the number of Openflow instances is 3 for example, but the invention is not limited thereto.
The expansion board card can copy the test message into three parts, compare the first part of the test message with the flow table 1, if the first part of the test message is matched with the flow table 1, process the first part of the test message according to the flow table 1, and send the processed test message to the expansion port 1; similarly, the expansion board card may compare the second test packet with the flow table 2, if the second test packet is matched with the flow table 2, process the second test packet according to the flow table 2, and send the processed test packet to the expansion port 2; and comparing the third test message with the flow table 3, if the third test message is matched with the flow table 3, processing the third test message according to the flow table 3, and sending the processed test message to the expansion port 3.
