[0077] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, a detailed description will be given below with reference to the accompanying drawings and specific embodiments.

[0078] It should be understood that references throughout this specification to "one embodiment" or "an embodiment" mean that a particular feature, structure, or characteristic associated with the embodiment is included in at least one embodiment of the present invention. Therefore, the appearances of "in one embodiment" or "in an embodiment" throughout this specification do not necessarily refer to the same embodiment. Furthermore, these particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0079] In various embodiments of the present invention, it should be understood that the size of the serial numbers of the following processes does not mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0080] Additionally, the terms "system" and "network" are often used interchangeably herein.

[0081] In the embodiments provided herein, it should be understood that "B corresponding to A" means that B is associated with A and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B based solely on A; B can also be determined based on A and / or other information.

[0082] The DCN channel mode for Metro Transport Network (MTN) / SPN / FlexEthernet (FlexE) interfaces uses MTN overhead, SPN overhead, FlexE overhead, or client-side service transmission. During the initial launch of a network element (NE), when no client is configured for control, control messages are transmitted with other NEs (such as neighboring NEs) using overhead frames. After launch, control messages are transmitted along the configured client service channel.

[0083] In the future-oriented decoupled and open scenario, the DCN mechanisms of various manufacturers need to be interoperable. To achieve interoperability, each process of network element online must meet standard requirements. However, there is currently no solution for how to test the interoperability mechanism of network element DCN online.

[0084] To this end, an embodiment of the present invention provides a test system that can implement DCN automated testing of MTN / SPN / FlexE. The test system includes a first device, a second device, and a third device.

[0085] The first device may be referred to as a test device, which is configured to send test instructions, receive test data, process the test data, and generate test results to implement DCN automatic testing of MTN / SPN / FlexE.

[0086] The second device may be referred to as a device under test, which may be several or more devices with FlexE interfaces or MTN devices or SPN devices.

[0087] The third device may be called a test instrument, which is used to capture packets.

[0088] The first device, ie the testing equipment, includes: a first module, a second module, and a third module.

[0089] like Figure 1 As shown, the first module, that is, the DCN test function logic module, is used to send test instructions to the second module and the third module, and process the test data received from the second module and the third module, and generate test results.

[0090] The second module, namely the DCN southbound interface control processing module, is used to send test instructions to the device, process the test data fed back from the device, and report the processed or unprocessed test data or test results to the first module.

[0091] The third module, namely the DCN instrument control processing module, is used to send test instructions to the test instrument, process the test data fed back from the instrument, and report the processed or unprocessed test data or test results to the first module.

[0092] like Figure 2 As shown, an embodiment of the present invention provides a test method for testing equipment. The method can be applied to MTN, SPN, or FlexE. The method may specifically include the following steps:

[0093] Step 11: Obtain a first message obtained from the device under test and a second message obtained from the target device.

[0094] The target device is an online network element device that is a neighbor of the device under test.

[0095] Optionally, this solution can be applied to MTN, SPN, or FlexE. Accordingly, the devices under test can be several or more devices with FlexE interfaces, or MTN devices, or SPN devices, etc. Of course, the embodiments of the present invention are not limited thereto.

[0096] Step 12: Allocate an IP address to the device under test according to the first message and the second message.

[0097] Optionally, this solution can be applied to MTN, SPN or FlexE. Accordingly, the first message can be a first MTN message, a first SPN message or a first FlexE message, and accordingly, the second message can be a second MTN message, a second SPN message or a second FlexE message.

[0098] Step 13: Get the IP address obtained from the captured packet.

[0099] Optionally, the above step 13 may specifically include: sending a third test instruction to the test instrument; and obtaining an IP address obtained by the test instrument through packet capture according to the third test instruction.

[0100] For example, after allocating an IP address to the device under test, a third test instruction is sent to the test instrument. The test instrument can capture test data from the device under test according to the third test instruction and report it to the test device. The test device parses the data to obtain the IP address carried therein, that is, obtains the IP address obtained by the captured packet.

[0101] Step 14: Determine the data communication network DCN test result according to the allocated IP address and the IP address obtained by packet capture.

[0102] Optionally, the test result is test passed or test failed.

[0103] Specifically, if the assigned IP address is consistent with the IP address obtained by packet capture, the DCN test result is determined to be passed; if the assigned IP address is inconsistent with the IP address obtained by packet capture, the DCN test result is determined to be failed. Optionally, if no IP address is obtained by packet capture in step 13 above, the DCN test result is also determined to be failed.

[0104] In the above scheme, by obtaining a first message obtained from the device under test and a second message obtained from the target device; and assigning an IP address to the device under test based on the first message and the second message; obtaining the IP address obtained by packet capture; and determining the data communication network DCN test result based on the assigned IP address and the IP address obtained by the packet capture, the DCN automatic detection of the flexible Ethernet is realized to ensure that the interoperability mechanism of the network element DCN can be realized.

[0105] like Figure 3 This is a schematic diagram of the test architecture of an embodiment of the present invention. The DCN test function logic module can obtain a first message obtained by the test instrument from the port of the device under test and / or the packet capture of the link between the device under test and the target device, as well as a second message from the target device, and perform DCN testing of MTN / SPN / FlexE based on the first message and the second message.

[0106] Optionally, obtaining the first message from the device under test includes:

[0107] Send a first test instruction to the test instrument; obtain a first message obtained by the test instrument from the device under test according to the first test instruction; wherein, the first message is obtained by the test instrument initiating a test packet capture from the port corresponding to the device under test and / or from the link between the device under test and the target device.

[0108] For example: the test device sends a DCN test message (i.e., a first test instruction) to the test instrument, and the test instrument initiates a test packet capture from the corresponding port of the device under test, and / or the link between the device under test and the target device (i.e., the neighboring online network element of the device under test) to obtain a first message and send it to the test device.

[0109] Optionally, obtaining a second message from the target device includes:

[0110] Send a second test instruction to the target device; and obtain a second message fed back by the target device according to the second test instruction.

[0111] For example: the test device sends a second test instruction to the target device. Since the target device is an online network element, the test device can directly capture the packet from the target device to obtain the test data (i.e., the second message), that is, the target device can send the corresponding test data (i.e., the second message) to the test device.

[0112] Optionally, allocating a first IP address to the device under test according to the first message and the second message includes:

[0113] Obtaining first DCN information from the first message; obtaining second DCN information from the second message; and allocating an IP address to the device under test if the first DCN information and the second DCN information are consistent.

[0114] The obtaining of the first DCN information from the first message includes:

[0115] According to the fixed bit block in the overhead frame corresponding to the first message, the DCN code block of the overhead frame is identified; according to the DCN code block, a media access control MAC frame is formed through Ethernet decoding; according to the device identification information and / or DCN identification information in the MAC frame, the first DCN information is identified and obtained.

[0116] Specifically, the test device identifies the overhead frame based on the overhead frame identifier, identifies the DCN code block of the overhead frame based on the fixed bit block in the overhead frame, and forms a MAC frame based on the DCN code block in one or more overhead frames through Ethernet decoding. The test device also identifies the DCN message (i.e., the first DCN information) based on one or more of the device identification information and the DCN identifier in the Ethernet 66 / 64B decoded MAC frame, thereby recovering the first DCN information from the first message. Optionally, the device identification information may include, but is not limited to, at least one of the following: chassis ID, system name, system description, IPv6 management address, and IPv4 management address.

[0117] Optionally, the second DCN information obtained from the second message may include: one or more of: DCN identification, rack number, system name, system description, IPv6 management address, and IPv4 management address, which can be understood as new network element information reported by the target device or new network element information stored in the target device queried by the test device.

[0118] Optionally, if the first DCN information and the second DCN information are consistent, allocating an IP address to the device under test includes:

[0119] If both the first DCN information and the second DCN information include target information, determining that the first DCN information and the second DCN information are consistent, and allocating an IP address to the device under test;

[0120] The target information is one or more of a DCN identifier, a rack number, a system name, a system description, an IPv6 management address, and an IPv4 management address.

[0121] Specifically, based on the recovered DCN message, the test device compares the new network element information reported by the target device received by the test device or the new network element information stored in the target device queried by the test device (such as DCN identification, rack number, system name, system description, IPv6 management address, IPv4 management address or one or more information). When one or more of the above information is consistent, the test device assigns a management IP address to the device under test.

[0122] Optionally, after allocating an IP address to the device under test, the method further includes: sending the IP address allocated to the device under test to the target device.

[0123] Optionally, the test device is capable of generating a test report for the corresponding test results. Specifically, the method further includes:

[0124] A test report is generated based on the DCN test results, wherein the test report includes one or more of the first DCN information, the second DCN information, the assigned IP address, and the IP address obtained by packet capture. In other words, the test includes: DCN messages identified from overhead frames, new network element information reported by the target device, the assigned IP address, and the IP address obtained by packet capture, etc., but the embodiments of the present invention are not limited to this.
