Background

For network security vendors, high performance throughput forwarding of firewalls becomes a serious concern for each vendor. With the development of computer technology, it is also crucial to test how the forwarding performance of firewalls is. In the prior art, the test can be performed through a hardware tester, however, different test types require different hardware testers to be purchased, and the test is expensive and inconvenient to unify.

The throughput test method is to simulate a client and a server and test the performance of UDP message forwarding of a pair of or a plurality of pairs of interfaces of a small packet with 64 bytes, a middle packet with 512 bytes and a long packet with 1518 bytes. For a tester to test firewall performance, its own throughput requirements must be wire-speed forwarded. In the prior art, the performance of the firewall can be tested by a software simulation mode based on the multi-core system, however, because a user may be random when configuring test IP addresses used for testing, especially when the number of the test IP addresses is small, severe load imbalance occurs when the multi-core system processes messages of the IP addresses, the forwarding performance requirement of the test is difficult to achieve, and a high-performance software testing method for testing the firewall is difficult to achieve.

Detailed Description

The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.

As shown in the background art, in the prior art, testing of the throughput performance of the firewall is usually realized by purchasing a high-performance hardware tester, or testing is performed based on a multi-core system or a platform design software testing method. However, the applicant has found through research that, for a software testing method, since a user generally configures a test IP address randomly, especially when the number of test IP addresses is small, a problem of severe load imbalance among multiple cores occurs when a multi-core system processes messages from each test IP address, the advantages of the multi-core system cannot be applied, and it is difficult to meet a forwarding performance requirement corresponding to a test, and it is difficult to implement a high-performance software testing method.

Based on this, the present disclosure provides the following examples. Fig. 1 is a flowchart of a throughput testing method applied to a multi-core system according to an embodiment of the present disclosure, where the method includes:

in step 11, configuration information is obtained, and quadruple information for testing is determined according to the configuration information, where each quadruple information includes a quadruple used for message transmission and message reception.

The user may pre-configure IP address information for testing, where the IP address information includes a plurality of test IP addresses for performing throughput testing. Therefore, after the user configuration is completed, the IP address information can be obtained by acquiring the configuration information. The throughput test function is mainly to simulate the client side to send messages and the service side to receive messages at the same time, and the quadruple information obtained in the embodiment comprises the quadruple used for sending and receiving the messages. Illustratively, in a quadruplet information, the quadruplet sent by the message is (source IP address Sip, destination IP address Dip, source port number Sport, destination port number Dport), and in the quadruplet information, the quadruplet received by the message is (Dip, Sip, Dport, Sport). In this embodiment, the quadruple information corresponding to each test IP address configured by the user may be determined according to each test IP address.

In step 12, the number of quadruplet information corresponding to the target forwarding core for the throughput test in the multi-core system is determined according to the total amount of the quadruplet information.

In the above example, each quadruple information includes a message sending quadruple and a message receiving quadruple, and the total amount of the quadruple information, the number of the message sending quadruple, the number of the message receiving quadruple, and the number of the test IP addresses included in the configuration information, which are determined based on the configuration information, are all the same.

Based on different forwarding performance requirements when the firewall is subjected to throughput testing, part or all of the forwarding cores can be selected for testing. And the selected forwarding core for performing the throughput test is the target forwarding core. In a possible implementation manner, if the forwarding performance requirement is low when the throughput test is performed, some forwarding cores may be selected as target forwarding cores to perform the test, and if the forwarding performance requirement is low when the throughput test is performed, all forwarding cores may be selected as target forwarding cores to perform the test.

In step 13, for each target forwarding core, determining a packet forwarding speed corresponding to each session in the target forwarding core according to the number of quadruple information corresponding to the target forwarding core and the test forwarding speed, where the session is created according to each target quadruple information in the target forwarding core, and the target quadruple information is the quadruple information of the packet forwarded by the target forwarding core.

The test forwarding speed is preset according to the performance requirement of the throughput test, and the test forwarding speed can be set to be greater than or equal to the forwarding speed of the firewall which actually needs to be tested. In this embodiment, after the number of target forwarding cores for performing the throughput test is determined, the target forwarding cores may be further determined, and a plurality of sessions exist in each target forwarding core, and then, a packet forwarding speed corresponding to each session in each target forwarding core may be determined, so as to ensure that the sum of the packet sending speeds of each session of each target forwarding core is the test forwarding speed.

For example, after the number of the quadruple information corresponding to each target forwarding core is determined, the target quadruple information corresponding to the target forwarding core may be further determined, so that a session may be created according to the target quadruple information.

In step 14, the target forwarding core forwards the test packet based on each session according to the packet forwarding speed corresponding to the session.

After the message forwarding speed corresponding to each session is determined, the test message forwarding can be performed based on the session, so as to perform throughput testing. Illustratively, the test forwarding speed is W, the number of target forwarding cores is N, and after the packet forwarding speed Vij of the jth session Sij of the ith target forwarding core Ci is determined, when performing throughput test, the test packet may be forwarded at the speed Vij based on the session Sij, that is, the number of packets forwarded by Vij in unit time based on the session Sij, so as to ensure that the number of packets forwarded by each session of each target forwarding core in unit time is W.

In order to make those skilled in the art understand the technical solutions provided by the embodiments of the present invention, the following detailed descriptions are provided for the above steps.

Optionally, in step 12, according to the total amount of the quadruple information, an exemplary implementation manner of determining the number of quadruple information corresponding to a target forwarding core for throughput testing in the multi-core system is as follows, and the step may include:

and determining the number of initial forwarding cores for forwarding the message according to the throughput test line speed.

The corresponding relationship between various wire speed throughputs and the number of forwarding cores can be set in advance according to an actual test scene. For example, a pair of interfaces for throughput testing of a large packet line speed is preset to correspond to two forwarding cores, so that when the throughput testing is performed, the number of the forwarding cores can be determined according to the corresponding relation and the throughput testing line speed, so as to meet the basic testing requirement in the throughput testing.

Then, determining whether the four-tuple information is evenly distributed to each initial forwarding core according to the total amount of the four-tuple information and the number of the initial forwarding cores;

For example, whether the quadruplet information can be evenly distributed to each initial forwarding core can be determined through mod remainder calculation based on the total amount of the quadruplet information and the number of the initial forwarding cores. As an example, if the total amount of the quadruplet information is Y and the number of the initial forwarding cores is M, the remainder calculation may be performed as follows:

R＝Y mod M；

if R is 0, that is, Y is divisible by M, it means that the quadruple information may be evenly allocated to each initial forwarding core, and if R is not 0, it means that the quadruple information may not be evenly allocated to each initial forwarding core.

In this example, when it is determined that the quadruple information is averagely allocated to each of the initial forwarding cores, the initial forwarding core is determined to be the target forwarding core, that is, it is determined that the number of forwarding cores for performing throughput testing is M, and the number (Y/M) of the evenly allocated quadruple information is determined to be the number of quadruple information corresponding to each of the target forwarding cores.

Therefore, by the technical scheme, the number of the forwarding cores for carrying out the throughput test in the multi-core system can be rapidly determined, and the corresponding quadruple information is uniformly distributed for each target forwarding core, so that the load balance of each target forwarding core is ensured, technical support is provided for carrying out the throughput test based on the test forwarding speed, and meanwhile, the accuracy and reliability of the test result of the subsequent throughput test can be improved.

Optionally, in step 12, another exemplary implementation manner of determining, according to the total amount of the quadruple information, the number of quadruple information corresponding to a target forwarding core for throughput testing in the multi-core system is as follows, and the step may further include:

In a possible implementation manner, when it is determined that the quadruplet information cannot be evenly distributed to each initial forwarding core, that is, R is not 0, it is determined whether there are other forwarding cores in the multi-core system, that is, it is determined whether the number Num of forwarding cores of the multi-core system is greater than the number M of the initial forwarding cores, and if Num is greater than M, it indicates that there are other forwarding cores in the multi-core system, at this time, the number of the initial forwarding cores is increased by one, so as to determine whether the total amount of the quadruplet information can be evenly divided by the number of the initial forwarding cores.

For example, if the number M of initial forwarding cores is 2, it is determined that R (Y mod 2) is not 0 and the number of forwarding cores in the multi-core system is 4, that is, it is determined that the quadruple information cannot be evenly distributed to each initial forwarding core, and the number of forwarding cores of the multi-core system is greater than the number of initial forwarding cores, the number of initial forwarding cores is increased by one, that is, M is M +1, and if M is 3, a step of determining whether the quadruple information is evenly distributed to each initial forwarding core, that is, it is determined whether R (Ymod 3) is 0 again, if Y mod 3 is 0, it indicates that the quadruple information can be evenly distributed to the 3 forwarding cores, and this step may be ended, and the number of initial forwarding cores (that is, M is 3) is determined as the number of target forwarding cores, and determining the number corresponding to the four-tuple information which is evenly distributed as the number of the four-tuple information corresponding to each target forwarding core, namely Y/3.

If Y mod 3 is not 0, where the number of forwarding cores of the multi-core system is 4 and is greater than the number of initial forwarding cores 3, then M is M +1, that is, M is 4, and it is determined whether R (Ymod 4) is 0 again. For example, when R (Y mod 4) is determined to be 0, the number of quadruple information corresponding to each target forwarding core may be determined to be Y/4 in the above manner; when it is determined that R (Y mod 4) is not 0, that is, it is determined that the quadruple information cannot be evenly distributed to each initial forwarding core, and the number of initial forwarding cores is equal to the number of forwarding cores of the multi-core system, which indicates that when all forwarding cores in the multi-core system are used for testing, the quadruple information cannot be evenly distributed to each initial forwarding core yet.

The following describes the determination of the number of quadruplet information corresponding to each class of forwarding cores in detail.

Illustratively, the number of the quadruplet information corresponding to the first forwarding core is obtained by rounding down the quotient of the total amount of the quadruplet information and the number of forwarding cores of the multi-core system, the number of the quadruplet information corresponding to the second forwarding core is obtained by rounding up the quotient of the total amount of the quadruplet information and the number of forwarding cores of the multi-core system, and the number of the second forwarding core is the remainder of the total amount of the quadruplet information and the number of forwarding cores of the multi-core system.

In this embodiment, when determining the number of the quadruple information corresponding to each of the first forwarding core and the second forwarding core, in order to ensure load balancing of each forwarding core to the maximum extent, the number of the first forwarding core and the second forwarding core may be determined according to the total amount of the quadruple information and the number of the target forwarding cores.

Illustratively, the number of target forwarding cores is 4, and a remainder R between the total amount of the quadruplet information and the number of forwarding cores of the multi-core system is determined to be 1, at this time, it may be determined that the number of second forwarding cores is 1, and the number of first forwarding cores is 3 (4-1). In this embodiment, for the first forwarding core, the number of the corresponding quadruplet information is obtained by rounding down the quotient of the total amount of the quadruplet information and the number of the forwarding cores of the multi-core system, for example, the number of the quadruplet information is P, and the number of the quadruplet information corresponding to the second forwarding core is P +1, so that 1 forwarding core may be selected from 4 forwarding cores of the target forwarding core as the second forwarding core, the number of the corresponding quadruplet information is P +1, the remaining 3 forwarding cores are the first forwarding cores, and the number of the corresponding quadruplet information is P. Therefore, when the quadruple information cannot be evenly distributed to each target forwarding core, the target forwarding cores are divided into the first forwarding core and the second forwarding core, so that the average degree of the number of the quadruple information corresponding to each target forwarding core can be ensured to a certain extent, the load balance of each target forwarding core is ensured, and technical support is provided for improving the accuracy of the test result of the throughput test.

In summary, according to the above technical solution, when it is determined that the quadruple information cannot be evenly distributed to each of the initial forwarding cores, the number of the quadruple information can be tried to be evenly distributed to each of the initial forwarding cores by increasing the initial forwarding cores one by one, so that it can be ensured that the number of the quadruple information corresponding to each of the target forwarding cores determined by the above method is relatively balanced, and not only can the utilization rate and load balance of each forwarding core in the multi-core system be ensured, but also the efficiency of the throughput test can be ensured, and the usage requirements of the user can be met.

Optionally, in step 13, for each target forwarding core, according to the number of the quadruplet information corresponding to the target forwarding core and the test forwarding speed, an exemplary implementation manner of determining a packet forwarding speed corresponding to each session in the target forwarding core is as follows, and the step may include:

and determining the quotient of the test forwarding speed and the number of the target forwarding cores as the message forwarding speed corresponding to each target forwarding core. After the target forwarding cores are determined, the message forwarding speed V ═ W/N corresponding to each target forwarding core can be determined according to the test forwarding speed.

As an example, when the number of sessions of the target forwarding core is the same, determining the quotient of the packet forwarding speed corresponding to the target forwarding core and the number of sessions as the packet forwarding speed corresponding to each session, where the number of sessions of the target forwarding core is the same as the number of quadruple information.

Illustratively, the number of sessions in each target forwarding core is P, and the packet forwarding speed V ═ V/P ═ W/N/P corresponding to each session.

As another example, in a case that the number of sessions of the target forwarding core is not all the same, determining a third forwarding core and a fourth forwarding core in the target forwarding core, wherein the number of sessions of the third forwarding core is one less than the number of sessions of the fourth forwarding core;

In this example, the number of sessions in the target forwarding core is not all the same, and in order to ensure that the packet forwarding speed corresponding to each target forwarding core is the same, the packet forwarding speed corresponding to part or all of the sessions in the target forwarding core needs to be set.

The manner of determining the third forwarding core and the fourth forwarding core in the target forwarding core is the same as the manner of determining the first forwarding core and the second forwarding core in the foregoing, and details are not described here again. Illustratively, the number of the sessions in the third forwarding core is determined to be P, and the number of the sessions in the fourth forwarding core is determined to be P + 1. Therefore, the packet forwarding speed corresponding to each session in the P third forwarding cores may be directly determined by the number of sessions, for example, V/P W/N/P. Therefore, the message forwarding speed corresponding to the target forwarding core can be guaranteed to be W/N.

For the fourth forwarding core, K sessions may be selected as second sessions, the number of the first sessions is P +1-K, the determined packet forwarding speed corresponding to the first session is W/N/P, the packet forwarding speed corresponding to the second session is ((K-1)/K) × (W/N/P), and the packet forwarding speed corresponding to the fourth forwarding core is also W/N and is the same as the packet forwarding speed corresponding to the third forwarding core by using the following formula:

V＝(P+1-K)×(W/N/P)+K×((K-1)/K)×(W/N/P)

＝(P+1-K)×(W/N/P)+(K-1)×(W/N/P)

＝((P+1-K)+(K-1))×(W/N/P)

＝W/N

For example, if the value of K is 2, the packet forwarding speed corresponding to the first P-1 sessions in the fourth forwarding core may be set to V, and the packet forwarding speed corresponding to the last 2 sessions in the fourth forwarding core may be set to V/2, so as to ensure that the packet forwarding speed corresponding to the fourth forwarding core is V.

Therefore, by the technical scheme, the packet forwarding speeds corresponding to the third forwarding core and the fourth forwarding core with different session numbers are the same, load balance of each target forwarding core for performing throughput testing in the multi-core system is further ensured, throughput performance of the multi-core system can be linearly increased along with increase of the number of the forwarding cores, and the use range of the throughput testing method is widened.

Optionally, after the step 12 of determining the number of quadruplet information corresponding to a target forwarding core for throughput testing in the multi-core system according to the total amount of the quadruplet information, the method may further include:

and determining the message distribution parameters of the network card according to the quantity of the quadruple information corresponding to each target forwarding core. For example, the network card may perform message distribution according to an RSS (receive Side scaling) algorithm, and the message distribution parameter may be an RSS key in the RSS algorithm.

For example, the exemplary implementation manner of determining the message distribution parameter of the network card for the four-tuple number corresponding to each target forwarding core may include:

obtaining an initial message distribution parameter, wherein the initial message distribution parameter may be a set default value.

And carrying out message distribution test on the four-tuple information according to the initial message distribution parameters and the number of the target forwarding cores. For example, N packets may be generated according to the number N of target forwarding cores, and then the results of RSS calculation performed on the Y quadruple information may be hashed based on the initial packet distribution parameter to obtain a hash value, and a packet to which each quadruple information belongs is determined according to the hash value.

In step 12, the number of the quadruple information corresponding to each target forwarding core is determined, so that if the number of the quadruple information in any packet obtained based on the initial message distribution parameter exceeds the target threshold, it indicates that the initial message distribution parameter cannot be distributed according to the determined number of the quadruple information corresponding to each target forwarding core, and at this time, the initial message distribution parameter needs to be updated until a message distribution parameter that can satisfy that the number of the quadruple information in any packet does not exceed the target threshold is determined. Therefore, the messages received by the network card can be evenly distributed through the configuration of the network card hardware, the average degree of the number of the messages in each network card queue is ensured, and the load balance of each target forwarding core is ensured.

And then, determining the target four-tuple information corresponding to each target forwarding core according to the message distribution parameters. For example, after the message distribution parameter is determined, the four-tuple information may be distributed in the same manner as described above to obtain the four-tuple information corresponding to each group, and the number of the four-tuple information in each group does not exceed the target threshold. The packet corresponds to the target forwarding core one to one, and then the quadruple information in the packet can be determined as the quadruple information corresponding to the target forwarding core corresponding to the quadruple information.

In this embodiment, after determining the target quadruple information corresponding to each target forwarding core, a session corresponding to each quadruple information may be directly created in the target forwarding core for each quadruple information. Therefore, when the network card receives the message, the message can be distributed to the forwarding core where the session of the message is located according to the message distribution parameters and the quadruple of the message, so that the message can be directly forwarded based on the session in the forwarding core, on one hand, the session does not need to be established in the process of test forwarding, thereby effectively reducing the extra overhead in the process of message forwarding, improving the efficiency of message forwarding, and ensuring the accuracy of the throughput test of the firewall based on the multi-core system. On the other hand, a session can be created in advance for each target forwarding core, the sessions in different forwarding cores are different, and the message can be directly sent to the forwarding core corresponding to the session based on the network card, so that the overhead of core reversing in the message forwarding process is further reduced, and the efficiency of throughput testing is further improved.

Optionally, in step 14, according to the packet forwarding speed corresponding to each session, an exemplary implementation manner of performing test packet forwarding based on the session is as follows, and the step includes:

and taking the session identifier of the session as a message identifier of a header of a test message, and forwarding the test message at the message forwarding speed, wherein the session identifier is an ID of the session in a session array of the target forwarding core.

In the prior art, when a throughput test is performed, if the number of configuration sessions is large, when a packet forwarding query session is performed, the query is slow due to a large number of sessions, the probability of query miss is increased, and the consumption performance is high, so that the performance of receiving and sending packets is reduced. Therefore, in the embodiment of the present disclosure, a session corresponding to each target forwarding core is created in advance according to the quadruple information corresponding to the target forwarding core, and when a test packet is generated and forwarded, a session identifier of the session corresponding to the test packet is used as a packet identifier of a header of the test packet, so that a session corresponding to the session identifier is directly queried according to the session identifier, a query miss situation in the prior art does not occur, and efficiency and accuracy of session query can be effectively improved.

Based on this, the method further comprises:

determining a session corresponding to the received message from the session array according to the message identifier under the condition that the message identifier belongs to a target range; the target range is a range which is greater than or equal to 0 and less than or equal to the number of sessions of the target forwarding core.

And processing the received message according to the determined session.

In this embodiment, when a message is received, the message identifier may be directly obtained from the header of the message. If the message is used for carrying out the throughput test, the message identifier is the session identifier, so that the corresponding session can be directly determined from the session array according to the message identifier, and the message is forwarded based on the session. Illustratively, the session array is sess _ quick [ ], and the message identifier in the header of the test message is 2, then the session corresponding to the message can be directly determined to be sess _ quick [2], so that the session corresponding to the test message can be rapidly determined.

After the message identifier is obtained, whether the message is a message for performing a throughput test can be determined by determining whether the message identifier belongs to a target range, and a session can be directly determined from a session array according to the message identifier and the message can be processed under the condition that the message identifier belongs to the target range. Therefore, the message identification is added in the constructed test message header, the processing efficiency of the received message is improved, the session query process corresponding to the message is simplified, the session query efficiency and accuracy are improved, and technical support can be provided for calculating the whole test throughput.
