detailed description

In the embodiment of the present invention, a first test instance is selected in all the test cases of the Ethernet port, where the test instance includes a transmission rate supported by the Ethernet port and a network type corresponding to the transmission rate; The test example configures communication parameters of the Ethernet port; during the data transmission process, the state parameter of the PCS of the Ethernet port is detected, and the state of the detected PCS is compared with the theory of the first test example. The state parameters are compared. When the difference between the detected state parameter of the PCS and the theoretical state parameter meets a preset condition, data is transmitted by using the communication parameter currently configured by the Ethernet port.

The present invention will be further described in detail below with reference to the embodiments.

The embodiment of the invention provides a method for adaptive network speed matching method, as shown in FIG. 1 . The method includes:

Step 101: Select a first test instance in all test cases of the Ethernet port, where the test case includes a transmission rate supported by the Ethernet port and a network type corresponding to the transmission rate.

There are many transmission rates for Ethernet, such as 10Mbps, 100Mbps, and 1000Mbps. Each different rate corresponds to one or more network types. For example, 10Mbps corresponds to 10base-T, 100Mbps corresponds to 100base-TX, 100base-FX, etc. 1000Mbps corresponds to 1000base-T; in practice, generally Ethernet ports support multiple rates. Therefore, there may be multiple test cases for one transmission rate. For example, there are 100Mbps 100base-TX and 100Mbps 100base-FX test cases at 100Mbps. The examples need to be tested separately.

In this step, a test case selected in the test case supported by the Ethernet port is tested. It may be that the transmission rate of the test case is not equal to the current actual transmission rate of the Ethernet port or the network type is not equal to the The type of network type currently used by the Ethernet port.

Step 102: Perform communication parameter configuration on the Ethernet port according to the first test example.

Obtaining a transmission rate and a network type corresponding to the first test instance, obtaining communication parameters related to the transmission rate and the network type in the Ethernet protocol, thereby configuring communication parameters of the Ethernet port, so that the Ethernet port is tested by the first test For example, the corresponding transmission rate and network type are used for data transmission.

In this step, after the communication parameter configuration of the Ethernet port is completed, the status register of the PCS needs to be cleared to zero.

Step 103: In the data transmission process, detecting a state parameter of the PCS of the Ethernet port after the communication parameter is configured, and comparing the detected state parameter of the PCS with a corresponding theoretical state parameter of the first test example, When the difference between the detected state parameter of the PCS and the theoretical state parameter meets a preset condition, data transmission is performed by using the communication parameter currently configured by the Ethernet port.

The PCS is in the physical layer, and the PCS is located between the RS (Reconciliation Sublayer) and the PMA (Physical Medium Attachment). The PCS is responsible for mapping well-defined Ethernet MAC functions to existing code and physical layer signal system functions. For different transmission rates and network types, PCS requires different implementation methods, such as codec method, scrambling and descrambling method, synchronization detection method, error detection detection method and so on. When the transmission rate corresponding to the first test instance is not equal to the actual transmission rate during the current data transmission of the Ethernet port or the network type is not equal to the network type currently used by the Ethernet port, the status parameter of the PCS may appear. Abnormal; therefore, the state parameter of the PCS can be used to determine whether the transmission rate in the first test example is equal to the current actual transmission rate of the Ethernet port, and whether the network type in the first test example is equal to the current use of the Ethernet port. Network Type. This method has the advantages of simplicity, convenience and high accuracy.

In the embodiment of the present invention, the adaptive network speed matching method further includes: when all the difference between the detected state parameter of the PCS and the theoretical state parameter does not meet the preset condition, in all test cases of the Ethernet port Selecting a second test example; configuring communication parameters of the Ethernet port according to a transmission rate supported by the Ethernet port included in the second test instance and a network type corresponding to the transmission rate; and during data transmission And detecting, according to the state parameter of the PCS of the Ethernet port after the communication parameter configuration of the second test example, detecting the PCS of the Ethernet port that is configured based on the communication parameter of the second test example The state parameter is compared with a corresponding theoretical state parameter of the second test case;

When the detected difference between the state parameter of the PCS of the Ethernet port based on the communication parameter configuration of the second test instance and the theoretical state parameter meets a preset condition, the current configuration of the Ethernet port is configured. Communication parameters for data transmission;

When the detected difference between the state parameter of the PCS of the Ethernet port and the theoretical state parameter based on the communication parameter configuration of the second test example does not meet the preset condition, all test cases on the Ethernet port Use other test cases until the completion of the Ethernet port The parameter configuration, or all test cases of the Ethernet port are all selected.

Here, when the detected status parameter of the PCS is abnormal, it can be determined that the transmission rate in the first test example is not equal to the current actual transmission rate of the Ethernet port or the network type in the first test example is not equal to the Ethernet. The network type currently used by the network port; in this case, you need to continue the test, that is, select a test case from the transmission rate supported by the Ethernet port, test again, repeat the above test until the PCS status parameter is normal or All test cases were tested.

In the embodiment of the present invention, the communication parameter configuration of the Ethernet port according to the first test example includes: a transmission rate supported by an Ethernet port included in the first test example, and a transmission rate. Corresponding network type, the PCS codec mode, the descrambling mode, the synchronous detection mode, the error correction detection mode and the bit width conversion mode are configured for communication parameters;

The configuration of the communication parameter of the Ethernet port according to the second test example includes: according to the transmission rate supported by the Ethernet port included in the second test example, and the network type corresponding to the transmission rate, The communication parameters are configured for the codec mode, the descrambling mode, the synchronous detection mode, the error correction detection mode, and the bit width conversion mode of the PCS.

In an Ethernet port, when the transmission rate or network type is different, the PCS needs different implementation methods; therefore, when configuring different transmission rates or network types for the Ethernet port, it is necessary to make an adaptive adjustment to the PCS.

In the embodiment of the present invention, the state parameter of the PCS includes: a codeword synchronization state value;

The codeword synchronization state value (block_lock) is a Boolean type. When the codeword received by the PCS from the PMA satisfies the block division, the codeword synchronization state value is true, and the meaning represented by it is the synchronization state of the received codeword. Different transmission rates correspond to different synchronization detection mechanisms, mainly including: synchronous detection of 8b\10b codec, synchronous detection of 64b\66b codec, synchronous detection of FEC and RS-FEC synchronization detection, etc.; if the PCS is not working properly, an error occurs when these synchronization mechanisms are performed, that is, the codeword synchronization status value is set to No.

In the embodiment of the present invention, the state parameters of the PCS include: a codeword synchronization state value, a bit error rate judgment value, a number of data decoding errors, and a number of times of incorrect reception state values;

The difference between the detected state parameter of the PCS and the theoretical state parameter meets a preset condition, including: the codeword synchronization state value is true, the error rate determination value is no, and the data decoding error occurs. When the sum of the number of times and the number of times of receiving the status value is less than the preset value, the preset condition is met, otherwise the preset condition is not met.

Here, the bit error rate judgment value is a Boolean type; when the bit error rate is greater than 10^-4, the bit error rate judgment value is set to No at this time. In this way, the bit error rate determination value can be used to determine whether the PCS is working properly.

One of the functions of PCS is codec, for example: 8b\10b codec, 64b\66b codec, etc., errors will occur during this decoding process; therefore, the number of data decoding errors can be used to determine whether the PCS is working properly.

When the PCS receives the codeword, the status value is used to indicate the working state of the PCS; and when the state value of the PCS is RX_E, it indicates that an error has occurred; therefore, the number of times the error receiving state value can be set to the state value of the PCS RX_E The number of times, the number of times the status value is incorrectly received to determine whether the PCS is working properly.

In the embodiment of the present invention, the first test case is selected in all the test cases of the Ethernet port, and the second test case or other test cases are selected in all the test cases of the Ethernet port, and the principle followed is: Among the selected test examples, a test case having a large transfer rate is preferably selected.

The rate can be negotiated between Ethernet ports. The principle of negotiation takes precedence over the maximum transmission rate supported by both parties. Therefore, in order to reduce the number of tests, it is possible to give priority to a large transfer rate.

The embodiment of the invention provides an adaptive network speed matching method. During the working process of the Ethernet port, the method attempts to use the test example supported by the Ethernet port to connect to the Ethernet port. The communication parameter configuration is performed. During the process of transmitting data, several state parameters of the PCS are obtained, and then the state parameters are used to determine whether the PCS is working normally; if the operation is normal, it indicates that the communication parameter at this time conforms to the Ethernet network port. Otherwise, you need to obtain untested test cases to continue testing.

An embodiment of the present invention provides an adaptive network speed matching apparatus, as shown in FIG. 2, including a test instance generation module 1, a configuration module 2, and a first judgment module 3, wherein:

The test instance generating module 1 is configured to select a first test instance in all test cases of the Ethernet port, where the test case includes a transmission rate supported by the Ethernet port and a network type corresponding to the transmission rate;

In this module, a test case selected in the test case supported by the Ethernet port is tested. It may happen that the transmission rate of the test case is not equal to the current actual transmission rate of the Ethernet port or the network type is not equal to the The type of network type currently used by the Ethernet port.

The configuration module 2 is configured to perform communication parameter configuration on the Ethernet port according to the first test example;

In this module, after the communication parameter configuration of the Ethernet port is completed, the status register of the PCS needs to be cleared to zero.

The first judging module 3 is configured to detect a state parameter of the PCS of the Ethernet port after the communication parameter configuration in the data transmission process, and compare the state parameter of the detected PCS with the corresponding theory of the first test example. The state parameters are compared. When the difference between the detected state parameter of the PCS and the theoretical state parameter meets a preset condition, data is transmitted by using the communication parameter currently configured by the Ethernet port.

The PCS is in the physical layer, and the PCS is located between the RS (Reconciliation Sublayer) and the PMA (Physical Medium Attachment). The PCS is responsible for mapping well-defined Ethernet MAC functions to existing code and physical layer signal system functions. For different transmission rates and network types, PCS requires different implementation methods, such as codec method, scrambling and descrambling method, synchronization detection method, error detection detection method and so on. When the transmission rate corresponding to the first test instance is not equal to the actual transmission rate during the current data transmission of the Ethernet port or the network type is not equal to the network type currently used by the Ethernet port, the status parameter of the PCS may appear. Abnormal; therefore, the state parameter of the PCS can be used to determine whether the transmission rate in the first test example is equal to the current actual transmission rate of the Ethernet port, and whether the network type in the first test example is equal to the current use of the Ethernet port. Network Type. The device has the advantages of simplicity, convenience and high accuracy.

In the embodiment of the present invention, the device further includes:

The second test module 4 is configured to select a second in all test cases of the Ethernet port when the difference between the detected state parameter of the PCS and the theoretical state parameter corresponding to the first test instance does not meet the preset condition. a test example; configuring communication parameters of the Ethernet port according to a transmission rate supported by the Ethernet port included in the second test instance and a network type corresponding to the transmission rate; and detecting during the data transmission process Based on the state parameter of the PCS of the Ethernet port after the communication parameter configuration of the second test example, the detected based on the second test Comparing the state parameter of the PCS of the Ethernet port after the configuration of the communication parameter with the theoretical state parameter corresponding to the second test example; when the detected communication parameter configuration based on the second test example is detected When the difference between the state parameter of the PCS of the Ethernet port and the theoretical state parameter corresponding to the second test example meets a preset condition, data is transmitted by using the communication parameter currently configured by the Ethernet port; when detected The difference between the state parameter of the PCS of the Ethernet port and the theoretical state parameter corresponding to the second test instance after the communication parameter configuration of the second test example does not meet the preset condition, at the Ethernet port Other test cases are selected in all test cases until the communication parameters are configured for the Ethernet port, or until all test cases of the Ethernet port are selected.

Here, when the detected status parameter of the PCS is abnormal, it can be determined that the transmission rate in the first test example is not equal to the current actual transmission rate of the Ethernet port or the network type in the first test example is not equal to the Ethernet. The network type currently used by the network port; at this time, you need to continue testing, that is, select a test case from the transmission rate supported by the Ethernet port, test again, repeat the above test until the PCS status parameter is normal. Or all test cases are tested.

In the embodiment of the present invention, the first determining module 3 is further configured to: edit the PCS according to the transmission rate supported by the Ethernet port included in the first test example and the network type corresponding to the transmission rate.

In an Ethernet port, PCS requires different implementation methods when the transmission rate or network type is different. Therefore, when configuring different transmission rates or network types for Ethernet ports, you need to PCS makes adaptive adjustments.

Correspondingly, the difference between the detected state parameter of the PCS and the theoretical state parameter meets a preset condition, including: the codeword synchronization state value is true; otherwise, the preset condition is not met.

The codeword synchronization state value (block_lock) is a Boolean type. When the codeword received by the PCS from the PMA satisfies the block division, the codeword synchronization state value is true, and the meaning represented by it is the synchronization state of the received codeword. Different transmission rates correspond to different synchronization detection mechanisms, mainly including: synchronous detection of 8b\10b codec, synchronization detection of 64b\66b codec, synchronization detection of FEC, and synchronization detection of RS-FEC; if PCS is abnormal At work, an error occurs when these synchronization mechanisms are performed, that is, the codeword synchronization status value is set to No.

When the PCS receives the codeword, it uses the status value to indicate the working status of the PCS; and when the status value of the PCS is RX_E, it indicates that an error has occurred; therefore, the number of times the status value was received incorrectly It can be set to the number of times the status value of the PCS is RX_E, and the number of times the status value is incorrectly received to determine whether the PCS is working properly.
