Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for testing performance of an exchange according to an embodiment of the present invention, where the embodiment is applicable to a CPU performance test of a network-managed two-layer exchange, and the method may be executed by an exchange performance testing apparatus, where the apparatus may be implemented by software and/or hardware, and the apparatus may be integrated in a device capable of communicating with the exchange, for example, a typical user terminal device, such as a portable computer or a desktop computer. The method specifically comprises the following steps:
s110, the performance monitor sends a communication command to the switch to be tested so as to monitor communication parameters of the switch to be tested and operation parameters of the switch to be tested, wherein the switch to be tested obtains data packets sent by the data packet sending instrument according to a set packet sending rate in real time.
The set packet sending rate refers to a packet sending rate received by a data packet sender, and may be a packet sending rate input manually or a packet sending rate set automatically by a performance monitor.
Preferably, the performance monitor is provided as a computer. Since the present embodiment performs the performance test on the CPU of the network-manageable two-layer switch, the switch to be tested is preferably set as the network-manageable two-layer switch. The CPU of the network-manageable two-layer switch mainly processes two types of Data packets, namely, two-layer Protocol Data packets such as Bridge Protocol Data Unit (BPDU) Data packets and ARP Data packets, and management Data packets such as web Data packets, Simple Network Management Protocol (SNMP) Data packets, and remote terminal Protocol (Telnet) Data packets, in which the destination MAC address is the MAC address of the CPU of the switch to be tested, so that the Data packet sent by the Data packet sender is preferably one or both of the Protocol Data packet and the management Data packet. The premise of performing the performance test is that the switch to be tested is in a normal operation state, so the operation parameters of the switch to be tested are preferably at least one of the conditions that whether a CPU is overloaded, whether a memory is leaked, whether a system process is lost, whether the switch to be tested has power failure, restart or crash and the like.
Specifically, the data packet and the packet sending rate sent by the data packet sender are firstly set, that is, the data packet sender sends the protocol data packet and/or the management data packet, and the packet sending rate for sending the data packet is set. And then, the data packet sending instrument sends the data packets to the switch to be tested according to the setting, and the switch to be tested acquires the data packets in real time and processes the data packets correspondingly. Meanwhile, the performance monitor is in communication connection with the switch to be tested, on one hand, sends a communication command such as an Internet Packet locator (PING) command, a Trace Router (tracerouter, TRACERT) command or a routing node Packet loss rate (patpinging) command to the switch to be tested, and returns information according to the processing of the switch to be tested on the communication command, so as to monitor the communication parameters of the switch to be tested, and on the other hand, monitors the operation parameters of the switch to be tested, so as to be used as a judgment basis of S120.
Illustratively, the sending, by the performance monitor, a communication command to a switch under test to monitor communication parameters with the switch under test comprises: the performance monitor sends a PING command to the switch to be tested; and the performance monitor monitors the packet loss rate and/or the time delay of a data packet returned by the PING command as a communication parameter with the switch to be tested.
Specifically, the performance monitor sends a PING command to the switch to be tested, and determines any one or two of a packet loss rate and a time delay of communication between the performance monitor and the switch to be tested according to a return data packet of the PING command, as a communication parameter between the performance monitor and the switch to be tested. The advantage of such setting is that the PING command can rapidly acquire the communication parameters of the performance monitor and the switch to be tested, and the communication parameters are set to be the packet loss rate and/or the time delay, so that the communication condition between the performance monitor and the switch to be tested, namely whether the communication is normal or not, can be determined intuitively.
And S120, the performance monitor determines whether the switch to be tested meets the set performance condition according to at least one of the set packet sending rate, the communication parameters and the operation parameters.
The set performance refers to the performance of the to-be-tested switch CPU, which may be the maximum packet sending rate that the to-be-tested switch CPU can bear, or the CPU packet sending rate that the to-be-tested switch that a user needs can bear. It should be noted that, here, the packet sending rate is used to represent the CPU performance, because the main processing object of the switch CPU to be tested is the protocol data packet and/or the management data packet acquired by the switch to be tested, and then the amount of the data packet of the corresponding type processed by the CPU determines the performance of the switch CPU to be tested. The packet sending rate of the data packet sender determines the amount of the data packets which are obtained and processed by the switch to be tested within a certain time, so that the CPU performance of the switch to be tested can be represented by directly utilizing the packet sending rate of the data packet sender.
Accordingly, the set performance condition is a judgment condition for judging whether the switch to be tested reaches the set performance. For example, the setting of the performance condition may include that the communication parameter is within a set communication parameter interval and the operation parameter is normal, which corresponds to the performance monitor automatically monitoring the maximum packet transmission rate that the CPU can bear (CPU maximum performance). Or, the setting of the performance condition includes that the set packet sending rate is not less than the set required packet sending rate, the communication parameter is in the set communication parameter interval, and the operation parameter is normal, which corresponds to the case that the performance monitor monitors whether the packet sending rate borne by the CPU meets the packet sending rate required by the user (CPU required performance).
The communication parameter interval is set to represent the communication parameter range of normal communication between the switch to be tested and the performance monitor. If the communication parameter is less than or equal to the interval maximum value of the communication parameter interval, the communication condition is normal; if the communication parameter is greater than the maximum value of the interval, the communication condition is abnormal. For example, for PING communication, the set communication parameter interval corresponds to a numerical range of packet loss rate and/or delay, the minimum value of the interval may be set to be slightly greater than the packet loss rate (usually zero) and/or delay during normal communication, that is, a numerical value at which the packet loss rate and/or delay just start to increase, and the maximum value of the interval may set a corresponding packet loss rate and/or delay numerical value according to actual conditions. Of course, the interval maximum value may also be set as the interval minimum value, that is, the communication parameter interval is set as a single point value. The set required packet sending rate is the packet sending rate of the data packet sending instrument set by the user according to the required CPU performance.
Specifically, the performance monitor may compare the set packet sending rate with the set required packet sending rate, or compare the communication parameter with the set communication parameter interval, or determine whether the operation parameter is normal, or determine whether the switch to be tested satisfies the set performance condition by any one or a combination of several of the operation parameters.
It should be noted that the communication parameter is set as the set performance condition here, because the communication parameter between the performance monitor and the switch to be tested can well reflect whether the CPU load of the switch to be tested reaches the maximum performance of the CPU or the performance required by the CPU, for example, the packet loss rate and/or the time delay starts to increase, which indicates that the CPU resource consumption of the switch to be tested has exceeded the normal loadable range, that is, the maximum performance of the CPU is reached. Moreover, the influence of the communication between the two on the CPU performance of the switch to be tested is negligible compared with the influence of the processing protocol data packet and/or the management data packet on the CPU performance of the switch to be tested, that is, the communication between the two has little influence on the CPU performance.
S130, if not, the performance monitor executes a packet sending rate adjusting strategy so that the data packet sending instrument changes the current packet sending rate.
Specifically, if it is determined in S120 that the switch to be tested does not satisfy the set performance condition, the performance monitor executes a packet sending rate adjustment policy, for example, the performance monitor automatically adjusts or prompts the user to manually adjust the packet sending rate of the data packet sender according to a numerical adjustment method such as a binary method with high numerical adjustment efficiency. And then, returning to execute S110-S130 until the switch to be tested meets the set performance condition in S120, and executing S140.
And S140, if so, the performance monitor acquires the packet sending rate of the data packet sender as the CPU performance parameter value of the switch to be tested when the switch to be tested meets the set performance condition.
Specifically, if it is determined in S120 that the switch to be tested satisfies the set performance condition, the performance monitor automatically or prompts the user to manually obtain the packet sending rate of the packet sender as the CPU performance parameter value of the switch to be tested when the switch to be tested satisfies the set performance condition.
The technical scheme of the embodiment is that a communication command is sent to a switch to be tested so as to monitor communication parameters of the switch to be tested and operation parameters of the switch to be tested, wherein the switch to be tested acquires a data packet sent by a data packet sending instrument according to a set packet sending rate in real time; if the switch to be tested does not meet the set performance condition according to at least one of the set packet sending rate, the communication parameters and the operation parameters, executing a packet sending rate adjustment strategy to enable the data packet sending instrument to change the current packet sending rate; returning to execute the operation of sending a communication command to the switch to be tested so as to monitor the communication parameters of the switch to be tested and the operation parameters of the switch to be tested until the performance monitor determines that the switch to be tested meets the set performance condition; and when the switch to be tested meets the set performance condition, the packet sending rate of the data packet sending instrument is obtained and used as the CPU performance parameter value of the switch to be tested. The problem that the network-managed two-layer switch cannot test the CPU performance of the network-managed two-layer switch is solved, and the CPU performance of the network-managed two-layer switch is quickly and effectively tested, so that the performance test of the network-managed two-layer switch is more comprehensive.
Example two
Fig. 2 is a flowchart of a switch performance testing method according to a second embodiment of the present invention, and this embodiment further describes S120 on the basis of the foregoing embodiment, and sets the packet sending device as a hardware execution mode, that is, further optimizes S130 and S140. Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted. The method of the embodiment comprises the following steps:
s210, the performance monitor sends a communication command to the switch to be tested so as to monitor communication parameters of the switch to be tested and operation parameters of the switch to be tested, wherein the switch to be tested obtains data packets sent by the data packet sending instrument according to a set packet sending rate in real time.
S220, the performance monitor determines whether the switch to be tested meets the set performance condition according to at least one of the set packet sending rate, the communication parameters and the operation parameters.
According to the description of S120 in the first embodiment, the setting of the performance condition may include that the communication parameter is within a set communication parameter interval, and the operation parameter is normal. This situation corresponds to the performance monitor using the set performance conditions to test the maximum performance that can be achieved by the CPU of the switch under test.
Then, the switch under test satisfying the set performance condition corresponds to:
a1, in a set time period, the performance monitor judges that the communication parameter is in the set communication parameter interval and the operation parameter is normal. This situation corresponds to the CPU performance of the switch under test just reaching its maximum performance, at which point the CPU performance test may be stopped, i.e. the steps of S230 or S250 are not executed any more, and S240 or S260 is executed directly.
Accordingly, the switch under test not satisfying the set performance condition corresponds to:
b1, in a set time period, the performance monitor judges that the communication parameter is not in the set communication parameter interval and/or the operation parameter is abnormal.
Further, the unsatisfied set performance condition B1 may be:
and B11, in a set time period, the performance monitor judges that the communication parameter is smaller than the minimum interval value of the set communication parameter interval, and the operation parameter is normal. The situation corresponds to the normal communication condition of the switch to be tested, and the running condition is also normal, namely the switch to be tested does not reach the maximum performance of the CPU, the amount of the processed data packets can be continuously increased, namely the packet sending rate of the data packet sending instrument can be continuously adjusted upwards.
And B12, in a set time period, the performance monitor judges that the communication parameter is larger than the interval maximum value of the set communication parameter interval and/or the operation parameter is abnormal. The situation corresponds to the fact that the communication condition of the switch to be tested is abnormal, or the operation condition is abnormal, or both the communication condition and the operation condition are abnormal, namely the switch to be tested already reaches the maximum performance of the CPU, and the switch to be tested can not process all data packets acquired at present, namely the packet sending rate of the data packet sending instrument needs to be adjusted downwards, so that the data packet amount processed by the CPU of the switch to be tested is reduced.
According to the description of S120 in the first embodiment, the setting of the performance condition may further include that the set packet sending rate is not less than the set required packet sending rate, the communication parameter is within the set communication parameter interval, and the operation parameter is normal. This situation corresponds to the performance monitor using the set performance conditions to test whether the CPU performance of the switch under test meets the CPU performance required by the user.
Then, the switch under test satisfying the set performance condition corresponds to:
a2, in a set time period, the set packet sending rate is not less than the set required packet sending rate, the communication parameters are in the set communication parameter interval, and the operation parameters are normal. This situation corresponds to the packet amount that the packet amount processed by the switch CPU to be tested has already reached the user's demand, and the communication status of the switch to be tested is normal, and the operating conditions are also normal, i.e., the switch CPU performance to be tested is sufficient to meet the user's demand. At this time, it is preferable to stop the CPU performance test of the switch under test, i.e. not to execute the step of S230 or S250, but to directly execute S240 or S260, so as to save the test time and resource consumption. Of course, the user may also choose to continue the CPU performance test to determine the maximum performance of the CPU, and at this time, the execution may be continued according to the operation of testing the maximum performance of the CPU.
Accordingly, the switch under test not satisfying the set performance condition corresponds to:
and B2, in a set time period, the performance monitor judges that the set packet sending rate is less than the set required packet sending rate.
Further, the unsatisfied set performance condition B2 may be:
and B21, in a set time period, the performance monitor judges that the set packet sending rate is less than the set required packet sending rate, the communication parameter is less than or equal to the interval maximum value of the set communication parameter interval, and the operation parameter is normal. The situation corresponds to the data packet quantity processed by the CPU of the switch to be tested, which does not reach the data packet quantity required by the user, the communication condition of the switch to be tested is normal, the running condition is normal, namely, the switch to be tested does not reach the performance required by the CPU, the data packet quantity processed by the switch to be tested can be increased continuously, namely, the packet sending rate of the data packet sender can be adjusted continuously.
And B22, in a set time period, the performance monitor judges that the set packet sending rate is less than the set required packet sending rate, and the communication parameter is greater than the interval maximum value of the set communication parameter interval or the operation parameter is abnormal. This situation corresponds to the situation that the amount of the data packets processed by the CPU of the switch to be tested has not yet reached the amount of the data packets required by the user, but the communication condition, or the operation condition, or both the communication condition and the operation condition of the switch to be tested are abnormal, that is, although the CPU performance of the switch to be tested has not yet reached the CPU performance required by the user, the CPU performance has already reached the maximum CPU performance, and the switch to be tested cannot process all the data packets acquired at present. That is, the switch under test is not able to meet the user's requirement, and the CPU performance test of the switch under test is preferably stopped, i.e., no further operation is performed. Certainly, the user may also choose to continue to test the CPU performance of the switch to be tested to determine the maximum performance of the CPU for comparing the difference between the maximum performance of the CPU and the user requirement.
Specifically, the performance monitor may determine whether the switch under test satisfies the set performance condition according to the set packet sending rate, the communication parameter, the operation parameter, and any one of the above conditions, and then execute S230 or S240.
And S230, if not, the performance monitor displays prompt information for adjusting the current packet sending rate of the data packet sending instrument so as to prompt a user to adjust the current packet sending rate of the data packet sending instrument according to the prompt information, and the prompt information comprises a set adjusting method and/or an adjusting value.
The setting adjustment method is a preset adjustment method of packet sending rate, such as dichotomy.
Specifically, if it is determined in S220 that the switch to be tested does not satisfy the set performance condition, the performance monitor displays a prompt message for adjusting the current packet sending rate of the packet sending instrument, so that the user manually adjusts the packet sending rate of the packet sending instrument according to the prompt message, and then executes S210-S230 until it is determined in S220 that the switch to be tested satisfies the set performance condition, and executes S240.
For example, the user is prompted to adjust the current packet sending rate of the data packet sending instrument according to the set adjusting method and the set packet sending rate, or the user is directly prompted to specifically adjust the value. Whether the packet sending rate is adjusted up or down can be prompted according to the specific situation in S220. For example, if the performance monitor determines that the switch to be tested does not satisfy the set performance condition corresponds to B11 or B21 in S220, the user is prompted to adjust the current packet sending rate of the packet sender; and if the performance monitor determines that the condition that the switch to be tested does not meet the set performance condition corresponds to B12 or B22 in S220, the user is prompted to adjust the current packet sending rate of the packet sender downwards.
And S240, if so, the performance monitor acquires the system time when the switch to be tested meets the set performance condition, and displays the system time so that a user determines the packet sending rate corresponding to the system time in the packet sending log of the data packet sending instrument as the CPU performance parameter value of the switch to be tested.
The package sending log is a work record of the data package sending instrument and can record package sending time, package sending rate, package sending state and other information.
Specifically, if it is determined in S220 that the switch to be tested satisfies the set performance condition, the performance monitor acquires the system time when the switch to be tested satisfies the set performance condition, and then displays the system time, so that the user can manually determine the packet sending rate of the system time in the packet sending log of the data packet sender according to the system time, and the packet sending rate is used as the CPU performance parameter value of the switch to be tested.
The technical scheme of the embodiment solves the problem that the network-managed two-layer switch cannot test the CPU performance of the network-managed two-layer switch, realizes the manual adjustment of the packet sending rate of the data packet sending instrument, further manually determines the CPU performance parameter value of the switch to be tested, and can effectively test the CPU performance of the network-managed two-layer switch, thereby enabling the performance test of the network-managed two-layer switch to be more comprehensive.
EXAMPLE III
Fig. 3 is a flowchart of a method for testing performance of an exchange according to a third embodiment of the present invention, where in this embodiment, a data packet sender is set as a software execution mode based on the third embodiment, that is, if the data packet sender is not the same as the first embodiment, a packet sending rate adjustment policy is executed by a performance monitor so that the data packet sender changes a current packet sending rate, and if the data packet sender is the same as the second embodiment, the performance monitor obtains the packet sending rate of the data packet sender as a CPU performance parameter value of the exchange to be tested, and further optimizes the packet sending rate when the exchange to be tested meets a set performance condition. Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted.
Referring to fig. 3, the method of the present embodiment includes:
s310, the performance monitor sends a communication command to the switch to be tested so as to monitor communication parameters of the switch to be tested and operation parameters of the switch to be tested, wherein the switch to be tested obtains data packets sent by the data packet sending instrument according to a set packet sending rate in real time.
S320, the performance monitor determines whether the switch to be tested meets the set performance condition according to at least one of the set packet sending rate, the communication parameters and the operation parameters.
S330, if not, the performance monitor adjusts the current packet sending rate of the data packet sender according to the set adjusting method.
Specifically, if it is determined in S320 that the switch to be tested does not satisfy the set performance condition, the performance monitor may automatically adjust the current packet sending rate of the packet sending device according to the set packet sending rate, the set adjustment method, and the specific determination condition that the set performance condition is not satisfied, and then perform S310-S330, until it is determined in S320 that the switch to be tested satisfies the set performance condition, perform S340 and S350. For specific determination that the set performance condition is not satisfied, see the specific descriptions of B1, B11, B12, B2, B21, and B22 in example two S220.
For example, the current value of the packet sending rate can be automatically determined to be adjusted up or down according to the above specific determination in S220. The relationship between the up-regulation packet sending rate or the down-regulation packet sending rate and the specific determination condition in S220 can be referred to the specific description in the second embodiment S230, and the specific rate regulation value is automatically determined by the set packet sending rate and the set regulation method.
And S340, if so, the performance monitor acquires the system time and the packet sending log when the switch to be tested meets the set performance condition.
Specifically, if it is determined in S320 that the switch under test satisfies the set performance condition, the performance monitor automatically obtains the system time when the switch under test satisfies the set performance condition and the packet sending log of the packet sender, and then executes S350.
Of course, if the determination in S320 that the switch to be tested satisfies the set performance condition is the case a2 in the second embodiment S220, that is, the CPU performance of the switch to be tested already satisfies the CPU performance requirement of the user, but the CPU maximum performance of the switch to be tested has not been reached, and the user selects to continue the CPU performance test, the process may continue to return to S310-S330 until the switch to be tested is determined to satisfy the set performance condition corresponding to the CPU maximum performance in S320, and then the step is executed again.
And S350, taking the packet sending rate corresponding to the system time in the packet sending log as a CPU performance parameter value of the switch to be tested.
Specifically, after the performance monitor acquires the system time and the packet sending log, the performance monitor automatically determines the packet sending rate corresponding to the system time in the packet sending log as a CPU performance parameter value of the switch to be tested.
The technical scheme of the embodiment solves the problem that the network-managed two-layer switch cannot test the CPU performance of the network-managed two-layer switch, realizes automatic adjustment of the packet sending rate of the data packet sending instrument, further automatically determines the CPU performance parameter value of the switch to be tested, and achieves the effect of quickly and effectively testing the CPU performance of the network-managed two-layer switch, thereby enabling the performance test of the network-managed two-layer switch to be more comprehensive.
It should be noted that, for the adjustment of the packet sending rate and the automatic determination of the CPU performance parameter value, in addition to the implementation manner of the third embodiment, the adjustment may be implemented by establishing a communication connection between the packet sender and the performance monitor. For example, the performance monitor obtains a packet sending log of the packet sending instrument in real time, and sends the determined packet sending rate adjustment value to the packet sending instrument in real time, so that the packet sending instrument correspondingly adjusts the packet sending rate, and automatic adjustment of the packet sending rate and automatic determination of the CPU performance parameter value are realized.
