The performance testing method of network equipment provided by the embodiment of the present application will be described below with reference to the accompanying drawings.

As shown in Figure 3, the performance testing method of network equipment provided by the embodiment of the present application includes the following steps.

S300. The performance testing device generates a first message corresponding to the current test mode, and sends the first message to the network device (ie, the device under test 11 in Figure 1) to facilitate forwarding of the first message via the network device.

Current test modes include but are not limited to packet loss rate test mode, Acknowledge (ACK) protocol test mode, service loss test mode, service filtering test mode, and synchronization service test mode.

In actual applications, the current test mode can be switched according to actual needs. In different test modes, the performance testing device can determine the performance parameters of the network equipment based on the information of sent and received messages. In this way, some/all modules used to determine performance parameters in the performance testing device can be reused. Compared with existing testing methods, resource utilization is effectively improved.

Different test modes correspond to different message formats.

S301. The performance testing device obtains the first information and the storage location, and stores the first information in the shared cache space according to the storage location.

Among them, the size of the shared cache space is preset according to the maximum cache space of the network device. If the current test mode is a synchronous service test mode, the first information is the service type of the first message. If the current test mode is a mode other than the synchronization service test mode, the first information includes a sending identifier. The sending identifier is used to indicate that the first message has been sent.

The depth of the shared cache space is greater than or equal to the depth of the maximum cache space of the network device. The width of the shared cache space is m+1-n, m is the length of the sequence number of the message, m is a positive integer, 2 ⁿ is the maximum cache space of the network device, m+1-n>0.

The shared cache space includes a first shared cache space and a second shared cache space of the same size.

For example, the shared cache space adopts a ping-pong structure and includes the same two storage areas: storage area A and storage area B. The sequence number length of the message is 48, the depth of storage area A and storage area B are both 2 ⁿ , and the width of both is 49-n.

In different test modes, the performance testing device obtains the first information and stores the first information in different ways.

Optionally, if the current test mode is the packet loss rate test mode, the performance testing device uses the lower n bits of the sequence number of the first message as the storage location; adds the last bit of m-n bits in the sequence number of the first message. A preset character (used to represent that it has been sent), and the string obtained by adding the first preset character is used as the sending identification; the sending identification is stored in the storage location of the first shared cache space, and the sending identification is stored in the storage location of the second shared cache space. The storage location stores the second preset character.

Among them, the embodiment of the present application does not limit the contents of the first preset character and the second preset character. In actual applications, it can be configured according to actual needs.

For example, the length of the sequence number in the first message is 48 bits, and the low n bits will be used as the address where the sending identifier is stored. The performance testing device adds a 1 (corresponding to the first preset character) to the tail of the other 48-n bits in the serial number, except for the low n bits, to generate a sending identifier with a bit width of 49-n. The 1 added at the end indicates that a packet with this sequence number has been sent, and is used to test whether any packets are lost or retransmitted by the performance test device.

The sending side of the performance test device adds a 48-bit sequence number at the end of the message data load. Among them, the sequence numbers in the packets sent by the performance testing device increase one by one. When the performance testing device sends the first message, it first stores the sending identifier in the storage address of storage area A, and then stores all zeros (corresponding to the second preset character) in the same address of storage area B. When the storage address of storage area A is equal to the maximum cache space, the performance testing device will store the sending identifier in the storage address of storage area B when sending a message, and then store the full address in the same address in storage area A. Zero, and so on.

Optionally, if the current test mode is the service loss test mode, the performance testing device determines the starting position of the first shared cache space as the storage location; determines the lower 16 bits of the destination MAC address of the first message as the higher sending identifier. 16 bits; store the sending identifier in the storage location of the first shared cache space, and store the second preset character in the storage location of the second shared cache space.

For example, in the service loss test mode, the lower 16 bits of the destination MAC address of the first message are the virtual link number, and the higher 16 bits of the sending identifier are the virtual link number of the message.

Optionally, if the current test mode is a synchronous service test mode, the performance testing device determines the storage location as the starting location of the first shared cache space, obtains the service type, and stores the service type at the beginning of the first shared cache space. Location.

For example: the performance testing device obtains the service type and stores the obtained service type in address 0 of storage area A. Send a number identifying the business type.

It can be seen that the existence of the shared cache space constructed by the ping-pong structure can save resource space while retaining sufficient message identifiers to ensure that the identifiers of the messages in the transmission link are still being received when writing new message identifiers. will not be overwritten. The lower n bits can be shared as the address where the sending identification is stored.

Specifically, if the current test mode is another mode, the method for the performance testing device to store the first information in the shared cache space includes: determining the storage area range and the inspection area range of the shared cache space according to the storage location; storing the first information in the storage area range. a piece of information, and store a second preset character in the inspection area range.

Wherein, if the storage location is the address k of the first shared cache space, the performance testing device determines that the address range of the storage area is: [address k+1, 2 ⁿ -1 of the first shared cache space], and [second shared cache space The starting address of the cache space, the starting address of the second shared cache space + k].

The address range of the check area is determined to be: [the starting address of the first shared cache space, the starting address of the first shared cache space + k], and [the address of the second shared cache space k+1, 2 ⁿ -1] .

For example, as shown in Figure 4, the first shared cache space is cache space A, and the second shared cache space is cache space B. Then both cache space A and cache space B can be divided into checksum storage areas according to the above method. .

S302. The performance testing device receives the second message sent by the network device.

S303. The performance testing device obtains the second information, and updates the first information stored in the shared cache space to the second information.

If the current test mode is a synchronous service test mode, the second information is the service type of the second message. If the current test mode is a mode other than the synchronization service test mode, the second information includes an update identifier.

Specifically, if the current test mode is the synchronous service test mode, the performance testing device obtains the service type of the second message, and updates the service type stored in the first shared cache space to the service type of the second message.

If the current test mode is another mode, the performance testing device determines the update position based on the sequence number of the second message and the address range of the check area; and determines whether the second message is a duplicate based on the storage content located at the update position in the storage area. Send message. If the second message is not a retransmission message, the performance testing device updates the last character of the storage content located at the update position in the storage area to the second preset character to generate an update identifier.

For example, if the current test mode is other than the synchronous service test mode, when the packet is forwarded to the performance test device via the device under test, the performance test device extracts the 48-bit sequence number from the received packet, and Generate update address and update ID based on the serial number.

There is no overlapping area between the storage area range and the check area range of the shared cache space, so the performance testing device determines the update position based on the lower n bits of the 48-bit serial number and the address range of the check area range.

The method for the performance testing device to determine whether the second message is a retransmitted message based on the storage content at the updated position in the storage area is: the performance testing device determines whether the last character of the storage content at the updated position in the storage area is 0. If so, it is determined that the second message is a retransmitted message. If not, it is determined that the second message is not a retransmitted message.

For example, if the last bit of the storage content at the update position in the storage area is zero, it means that the message with this serial number has been received by the performance testing device, that is, the performance testing device determines that the second message is a retransmission message. arts. The performance testing device directly records the extracted 48-bit serial number into the register for the upper-layer application to read, and can even extract the virtual link number for the upper-layer application to read. If the last bit of the storage content located at the updated position in the storage area is not zero, it means that the performance testing device has not received the message, that is, the performance testing device determines that the second message is not a retransmitted message. The performance testing device sets the last position in the string with a bit width of 49-n in the shared cache space to 0 and leaves the other bits unchanged to obtain the update identifier. The update identifier is used to indicate that the message with this sequence number has been successfully received.

It can be seen that the performance testing device stores the first information in the shared cache space, which is helpful for determining whether the device under test is working normally. The performance testing device stores the second information in the shared cache space, which is helpful for determining whether a packet is lost based on the second information.

S304. When sending a message next time, the performance testing device determines the performance parameters of the network device according to the second information stored in the shared cache space.

If the current test mode is the packet loss rate test mode or the service loss mode, read the last character of the content in the check area; if the last character read is the second preset character, it is determined that the sent message has not been lost; If the last character read is the first preset character, it is determined that the sent message has been lost;

If the current test mode is the synchronous service test mode, when the test device sends a message again, it will first extract the service type from the starting position of storage area A, and compare the read service type and the sent service type to determine which type Type of sync frame lost.

For example, if the current test mode is the packet loss rate test mode, when the performance test device sends a message again, the number of sent messages is increased by one, because the storage location of the sent message is in the storage area. When checking whether any message is lost, When , the stored content will be extracted first from the same address in the check area. If the last bit of the stored content is 0, it indicates that the message has not been lost, and the number of received messages is increased by one. If the last bit of the stored content is 1, it indicates that the message is lost and the number of received messages remains unchanged. And the sequence number of the lost message can be obtained by adding the first 48-n bits of the stored content to the current check address.

If the current test mode is service loss mode, when the performance test device sends a message again, the stored content will be extracted from the same address in the inspection area. If the last bit of the stored content is 1, it indicates that the message is lost and the stored content can be extracted. The first 16 bits of the content, that is, the virtual link number, are reported to the upper-layer application to indicate what kind of service is lost.

If the current test mode is the synchronous service test mode, when the performance test device sends a message again, it will first extract the service type from address 0 of storage area A, and compare the read service type and the sent service type to determine which A type of synchronization frame loss.

It can be seen that when the message is sent again, the performance testing device determines the performance parameters (such as packet loss rate) of the network equipment, and can determine the real-time and accuracy of the performance parameters.

The performance testing method provided by the embodiments of this application can effectively distinguish between message retransmission and loss. During the test process, the impact of retransmission on packet loss rate calculation can be effectively ignored, making the test results more accurate and more applicable. For performance testing equipment, not only can the performance parameters of network equipment be determined through packet retransmission or packet loss, but also which type of business of the network equipment is abnormal can be effectively determined based on the sequence number of the packet.

The embodiment of the present application configures the shared cache depth of the performance testing device according to the maximum cache space of the device under test, effectively improving resource utilization. Configure the shared cache depth of the performance test device according to the maximum cache space of the device under test, and use ping-pong cache to effectively solve the above two problems, save resources and avoid conflicts, with obvious advantages.
