Detailed Description
Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Aiming at the problems that the prior network equipment forwarding performance test cannot accurately control the rate of sending messages and cannot quickly receive and send the messages, the invention controls the rate of sending test data and counts the time consumed by each test data passing through the tested equipment by using the clock period number of a CPU (central processing unit) in a TSC (time signal counter) register, and sends and receives the test data by using a sending buffer area and a receiving buffer area of a network card, thereby realizing the purposes of reducing the test cost, accurately controlling the rate of sending the test data and quickly receiving and sending the test data.
It should be noted that, in the present invention, a general-purpose network server based on X86 may be used as the test hardware, and as for the operating system, Linux, UNIX, or FreeBSD may be used to test the forwarding performance of the device under test.
To illustrate the method for testing the forwarding performance of the network device provided by the present invention, fig. 1 shows a flow of the method for testing the forwarding performance of the network device according to the embodiment of the present invention.
As shown in fig. 1, the method for testing forwarding performance of network device provided by the present invention includes:
s110: sending the generated test data to the tested equipment according to a preset rate, and then receiving the test data transmitted back from the tested equipment; the method comprises the steps that the rate of sending test data is controlled by using the number of CPU clock cycles in a TSC register, and the numerical value of the TSC register when each piece of test data is sent and received is recorded; meanwhile, the sending buffer area of the network card is used for sending the test data to the tested equipment, and then the receiving buffer area of the network card is used for receiving the test data forwarded back by the tested equipment.
Before sending the generated test data to the device to be tested according to the preset rate, the method further comprises the following steps: configuring a test type and test parameters; initializing a sending buffer, a receiving buffer and a TSC register according to the configured test type and the test parameters.
In the process of initializing the sending buffer area and the receiving buffer area, DMA mapping is carried out on the sending buffer area and the receiving buffer area, and the contents of the sending buffer area and the receiving buffer area are initialized according to the configured test type.
S120: and according to the recorded TSC register value, counting the time required by the whole test process from sending the test data to receiving the test data forwarded back from the tested device, and acquiring the forwarding performance parameters of the tested device.
The forwarding performance parameters of the tested equipment are obtained by configuring the time interval and counting the time required by the whole test process from sending the test data to receiving the test data forwarded back from the tested equipment in the configured time interval.
In order to make the method for testing the forwarding performance of the network device provided by the present invention more clearly embodied, fig. 2 shows a detailed execution flow of the method for testing the forwarding performance of the network device according to the embodiment of the present invention.
As shown in fig. 2, the execution flow of the method for testing the forwarding performance of the network device provided by the present invention is as follows:
s210: and configuring the test type and the test parameters.
Specifically, this step is to provide an interface for configuring the test type and the test parameters for the user, and after the test is completed, the test result can be returned to the user. The test type may be throughput, latency, number of TCP concurrent connections, TCP connection establishment rate, HTTP transaction rate, HTTP transmission rate, or the like. And the test parameters include common parameters and parameters associated with each test type.
The public parameters comprise a client network card, a server network card, whether the two-layer forwarding or the three-layer forwarding is tested, whether IPv4 or IPv6 is tested, a client IP address range, a source port range, a server IP address range, a destination port and the like; in addition, if three-layer forwarding is tested, the address of the client gateway and the address of the service end gateway also need to be configured.
The test parameters of throughput and time delay comprise data message length, test time, one-way or two-way and session number; in addition, the test parameters of the time delay also comprise the background flow; the test parameters of the TCP concurrent connection number further comprise the HTTP version number, the number of webpages of each HTTP connection GET and the webpage size.
S220: initializing a sending buffer, a receiving buffer and a TSC register according to the configured test type and the test parameters.
S230: after the initialization is completed, the test is started, and the generated test data is sent to the tested device.
The sending rate of the test data is controlled by using the CPU clock period number in the TSC register, and the value of the TSC register when each test data is sent is recorded.
S240: and after the tested device receives and forwards the test data, receiving the test data forwarded back from the tested device.
Receiving the forwarded test data by using a receiving buffer, and recording the TSC register value when each piece of forwarded test data is received;
s250: and counting the forwarding performance parameters of the tested equipment in the configured preset time interval according to the recorded TSC register values of each piece of test data in the transmitting and receiving processes.
Specifically, the clock cycle of the CPU consumed by the test data passing through the device under test, that is, the forwarding performance parameter of the device under test, can be obtained by subtracting the TSC register value recorded when the test data is transmitted from the TSC register value recorded when the test data is received.
For example, the TCP connection establishment rate of the network device needs to be analyzed in order to optimize the TCP connection establishment rate of the network device. At this time, the average CPU clock cycles consumed by the SYN message, the SYN-ACK message and the ACK message through the tested network equipment need to be counted respectively, so as to provide more useful information for developers. Generally, the SYN message is the first packet of a session, which consumes more time, and the SYN-ACK message and the ACK message consume much less time, and the two messages are not very different. If the test shows that the time consumed by the ACK message is more obvious than that consumed by the SYN-ACK message, the test shows that the problem possibly exists in the processing part of the ACK message by the network equipment, and developers can process the problem to achieve the purpose of optimizing the TCP connection establishment rate.
In addition, when the generated test data is sent to the device under test at a preset rate and then the test data forwarded back from the device under test is received, two problems need to be solved:
first is the timing accuracy problem. For example, in a 1000M network environment, for 64 bytes of data, if the transmission rate is to reach the line speed, the test instrument needs to transmit 1488096 data every second, i.e. one data every 1/1488096 seconds, and the ordinary timing method does not achieve such accuracy at all.
Therefore, the invention adopts the CPU clock period in the TSC register to time, so that when the test data is sent to the tested equipment, the CPU dominant frequency of the test hardware is 1GHz, and the theoretical timing precision can be 1/1000000000.
Second is the rate at which data is transmitted and received. Assuming that the ordinary network card using INTEL80x86 is used to drive the sending and receiving data, the efficiency of transceiving is greatly affected due to the need to apply and release buffers for each sent or received data packet, resulting in far insufficient performance, especially for 64-byte packets, a ten-gigabit network can only reach a marginal gigabit.
Therefore, the invention adopts a mode of repeatedly utilizing the network card sending buffer area and the receiving buffer area to send and receive the test data. The method comprises the steps of performing DMA mapping on a sending buffer area and a receiving buffer area only during initialization, initializing the sending buffer area and the receiving buffer area according to a test type, recording a field for keeping the sending test data unchanged in the test process, and directly modifying the value of a state bit of the buffer area instead of releasing the original buffer area after sending/receiving the test data each time so that the buffer area can send/receive the test data.
For example, the transmit buffer status bit and the receive buffer status bit may be set to 0 or 1. Wherein 0 represents that the transmission/reception of test data can be performed using the transmission/reception buffer; 1 indicates that the transmission/reception of test data using the transmission buffer/reception buffer is prohibited.
Specifically, in the initialization stage, both the transmit buffer status bit and the receive buffer status bit are set to 0, meaning that both buffers can be used to transmit/receive test data. When sending test data, the value of the sending buffer area status bit is set to 1, and after sending the test data, the value of the sending buffer area status bit is modified to 0, so that the sending buffer area can send data again. Similarly, when the receiving buffer receives the test data, the value of the receiving buffer status bit is set to 1, and after the test data is received, the value of the receiving buffer status bit is modified to 0, so that the receiving buffer can receive the data again.
Meanwhile, in order to count up accurate test results, the statistical accuracy of the time consumed by each type of test data passing through the tested device needs to be improved. For this reason, the present invention uses the CPU clock cycles in the TSC registers as the basis for statistical timing. The common special performance testing instrument cannot configure the time interval (usually 1 second) of performance data statistics, but in the invention, because the clock period number of the CPU in the TSC register is used as the time base, the statistical interval time can be configured to be less than 1 second, which is beneficial for developers to more flexibly perform statistics and analysis on the forwarding performance of the network equipment on a smaller time granularity.
In order to more clearly understand the method for testing the forwarding performance of the network device provided by the present invention, fig. 3 shows a flow for controlling the sending rate of the test data by using the TSC register according to an embodiment of the present invention.
As shown in fig. 3, the method specifically includes the following steps:
s310: setting the speed of sending test data and the number M of test data packets to be sent according to the test requirement;
s320: calculating the CPU clock period number N of the interval between two times of sending data packets according to the sending rate;
s330: initializing the number of the sent test data packets to be 0, and initializing the time of sending the test data packets last time to be 0;
s340: taking the value of the TSC register, and calculating the clock period number i of a time interval between the TSC register and the last data transmission;
s350, if i < N, which indicates that the time for sending the next test data packet is not yet, continuing to execute the step S340; if i > = N, then step S360 is executed to prepare for sending the next test data packet;
s360: before sending a data packet, setting the last data sending time as the value of the current TSC register;
s370: sending the next test data packet;
s380: adding one to the number of sent test packets;
s390: judging whether the number of the sent test data packets is less than M, if so, executing the step S340, continuing to execute circulation and sending test data; otherwise, the sending process of the test data is finished, and the sending is finished.
Therefore, the method for testing the forwarding performance of the network equipment can accurately control the speed of sending the test data by using the CPU clock period of the TSC register, and can achieve the aim of quickly sending and receiving the test data by repeatedly using the sending buffer area and the receiving buffer area.
In order to exhibit the effects of the present invention, the following description is given by way of example.
Example 1
A second-generation DELL R210 server and an XM2 performance testing instrument of IXIA company are used for respectively carrying out 64-byte UDP throughput testing and TCP connection establishment speed testing on a certain firewall product, wherein the 64-byte UDP throughput testing and the TCP connection establishment speed testing only differ by 5 ten thousandths of the test results, and the TCP connection establishment speed testing and the results differ by 3 thousandths of the test results.
Example two
A PCI-E Intel-82571 double-port gigabit network card is configured on a DELL R71 server, and when the TCP connection establishment rate is tested, the upper limit of the test exceeds 50 ten thousand, and when the HTTP transaction processing rate is tested, the upper limit of the test exceeds 7 thousand (the limit of the gigabit network card is reached at this time).
Example three
On a second generation DELL R210 server, a PCI-E X8 Intel-82599 double-port ten-thousand-million network card is configured, messages are transmitted and received by a mode of repeatedly utilizing a network card transmission buffer area and a network card receiving buffer area, for 64-byte messages, two ten-thousand-million ports can be transmitted to the linear speed by using one CPU, namely about 2976 ten-thousand messages can be transmitted per second, the CPU is more idle at the moment, one CPU is used under the same condition, the messages are transmitted by utilizing the pktgen of Linux, only about 394-ten-thousand messages can be transmitted per second, and the CPU occupies 100 percent.
It can be seen from the above examples that the method for testing the forwarding performance of the network device of the present invention can accurately test the performance value of the network device, and can provide more information for the developer in analyzing and optimizing the performance of the network device with a smaller time granularity in the development process of the network device.
