[0044] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0045] In the process of implementing this application, the inventors found that in large-scale systems, in order to ensure high-speed communication between nodes and reduce data transmission time, a complex point-to-point network topology is usually used between computing nodes. Although this topology has the advantages of simplicity, low latency, and high bandwidth, when the number of nodes increases, the number of connecting cables increases rapidly, resulting in a significant increase in the complexity of cable connection management. In the prior art, each cable is equipped with a unique electronic tag at both ends, and the user manually compares the connection topology diagram for inspection, which consumes a lot of manpower and is prone to human judgment errors.

[0046] In response to the above problems, the present application provides a cable misinsertion detection method, management node, system, device, and medium. The large-scale cable system detected by the method includes a management node and multiple business frames; wherein the management node is connected to all business frames for managing all business frame resources; each business frame has multiple boards, each board has multiple chips, and each chip is interconnected with other chips through multiple high-speed transmission links; the method includes: the management node determines the number of PRBS test packets sent tx_prbs_packets and the expected number of received rx_expect_prbs_packets for each high-speed transmission link; the management node sends tx_prbs_packets and rx_expect_prbs_packets to each chip belonging to each high-speed transmission link; the management node controls the controller on each high-speed transmission link of each chip to generate tx_prbs_packets PRBS test packets, and transmits the PRBS test packets to the receiving side through the cable; the management node controls the controller on the receiving side to verify the received PRBS test packets; the management node performs cable misinsertion detection according to the number of PRBS test packets received and the verification result. The method provided in the present application can detect the accuracy of cable connection, reduce labor costs, and solve the problem of cable connection errors caused by manual inspection in large-scale cable connection systems.

[0047] This embodiment provides a cable mis-insertion detection method, which detects a large-scale cable system such as Figure 1 As shown, it includes a management node and multiple service machine frames.

[0048] The management node is connected to all service chassis and is used to manage all service chassis resources.

[0049] Each service chassis has multiple boards, and each board has multiple chips, forming a complex topology.

[0050] Each chip is connected to other chips through multiple high-speed transmission links. The physical location of the chip in the system is composed of the business chassis number (chasis_id), the board number (blade_id), and the chip number in the board (chip_id). The physical location of the chip is as follows: Figure 2 The service frame number, board number, chip number, high-speed transmission link number, and point-to-point connection information of all high-speed transmission links are stored in the network topology connection database. The network topology connection database is generated by the management node according to the network connection topology diagram.

[0051] For example, the management node generates a network topology connection database based on the network connection topology diagram, and the network topology connection database records the business chassis number (chasis_id), board number (blade_id), chip number in the board (chip_id), link number (link_id), and point-to-point connection information of all high-speed transmission links.

[0052] Among them, the point-to-point connection information includes but is not limited to: the business frame number (peer_chasis_id) to which the connected peer link belongs, the board number (peer_blade_id) to which the connected peer link belongs, the chip number (peer_chip_id) to which the connected peer link belongs, and the high-speed transmission link number (peer_link_id) to which the connected peer link belongs.

[0053] In addition, the management node will also set and record the number of PRBS test packets sent (tx_prbs_packets) and the expected number of PRBS test packets received (rx_expect_prbs_packets) for each high-speed transmission link according to software rules.

[0054] For example, the management node first obtains the business chassis number (chasis_id), board number (blade_id), chip number in the board (chip_id), and link number (link_id) of the location of the opposite link from the network topology connection database, and then obtains the number of PRBS test packets sent (tx_prbs_packets) and the expected number of received packets (rx_expect_prbs_packets) according to the software rules.

[0055] Among them, the calculation formula for the number of PRBS test packets sent (tx_prbs_packets) obtained according to the software rules can be:

[0056] tx_prbs_packets=(chasis_id*BLADES_PER_CHASIS*CHIPS_PER_BLADE*LINKS_PER_CHIP)+(blade_id*CHIPS_PER_BLADE*LINKS_PER_CHIP)+(chi p_id*LINKS_PER_CHIP)+link_id+PRBS_PACKETS_BASE.

[0057] Among them, chassis_id is the service chassis number, BLADES_PER_CHASIS is the number of boards on the service chassis, CHIPS_PER_BLADE is the number of chips on the board, LINKS_PER_CHIP is the number of high-speed transmission links on the chip, blade_id is the board number, chip_id is the chip number, link_id is the high-speed transmission link number, and PRBS_PACKETS_BASE is the base value.

[0058] According to the above rules, each high-speed transmission link in the entire large-scale cable system can be set to send a different number of PRBS test packets.

[0059] The calculation formula for obtaining the expected number of received packets (rx_expect_prbs_packets) according to the software rule can be:

[0060] rx_expect_prbs_packets=(peer_chasis_id*BLADES_PER_CHASIS*CHIPS_PER_BLADE*LINKS_PER_CHIP)+(peer_blade_id*CHIPS_PER_BLADE*LINKS_PER_CHIP)+(peer_chip_id*LINKS_PER_CHIP)+peer_link_id+PRBS_PACKET S_BASE.

[0061] Among them, peer_chasis_id is the business chassis number of the connected peer link, BLADES_PER_CHASIS is the number of boards on the business chassis, CHIPS_PER_BLADE is the number of chips on the board, LINKS_PER_CHIP is the number of high-speed transmission links on the chip, peer_blade_id is the board number of the connected peer link, peer_chip_id is the chip number of the connected peer link, peer_link_id is the high-speed transmission link number of the connected peer link, and PRBS_PACKETS_BASE is the base value.

[0062] If PRBS_PACKETS_BASE is set to 0x1000, it means that the number of base packets is 0x1000. This base is both the base for the number of PRBS test packets sent and the base for the expected number of received packets.

[0063] Through the above rules, the exact number of PRBS test packets that each high-speed transmission link in the entire large-scale cable system will receive can be set.

[0064] See also Figure 3 The cable mis-insertion detection method provided in this embodiment is implemented as follows:

[0065] 301. The management node determines the number of PRBS test packets to be sent tx_prbs_packets and the expected number of PRBS test packets to be received rx_expect_prbs_packets for each high-speed transmission link.

[0066] In this step, the management node can directly read the number of PRBS test packets sent (tx_prbs_packets) and the expected number of PRBS test packets received (rx_expect_prbs_packets) for each link that are pre-set according to software rules and recorded.

[0067] 302. The management node sends tx_prbs_packets and rx_expect_prbs_packets to each chip to which each high-speed transmission link belongs.

[0068] 303 , the management node controls the controller on each high-speed transmission link of each chip to generate tx_prbs_packets PRBS test packets, and transmits the PRBS test packets to the receiving side through the cable.

[0069] This step is to perform the PRBS packet test process. For example, after each chip sets the tx_prbs_packets of each high-speed transmission link to the PRBS Tx Pattern Generator module of each link, each chip starts the PRBS packet test.

[0070] Each chip starts the PRBS packet test process as follows Figure 4 As shown, the PRBS module of the controller on the high-speed transmission link generates a PRBS code stream consisting of tx_prbs_packets PRBS test packets, which are sent to the other end by the TX of the high-speed port after packetization and transmitted to the receiving side of the other end by the cable.

[0071] 304. The management node controls the controller at the receiving side to verify the received PRBS test packet.

[0072] For example, after the receiving side receives the service data, its controller verifies the received data, identifies and counts the erroneous bits, and counts the number of erroneous bits, thereby confirming the connectivity of the cable and the link communication quality.

[0073] 305 , the management node performs cable mis-insertion prevention detection according to the number of received PRBS test packets and the verification result.

[0074] The implementation process of this step is as follows:

[0075] 305-1, determine whether the number of received PRBS test packets (such as rx_prbs_packets) is consistent with rx_expect_prbs_packets.

[0076] 305-2, if the check result is that there is an error bit (bit), the detection result is determined to be poor cable connection quality, and the construction personnel are notified to check the cable path quality. If the check result is that there is no error bit, and the number of received PRBS test packets is consistent with rx_expect_prbs_packets, the detection result is determined to be accurate cable connection. If the check result is that there is no error bit, but the number of received PRBS test packets is inconsistent with rx_expect_prbs_packets, the detection result is determined to be incorrect cable connection.

[0077] The cable misinsertion detection method provided in this embodiment utilizes the PRBS module to specify the characteristics of the number of PRBS packets. The management node connects the high-speed transmission link related information and software rules in the database through the network topology, and sends the number of PRBS test packets sent (tx_prbs_packets) and the expected number of PRBS test packets received (rx_expect_prbs_packets) of each high-speed transmission link in the system to each chip belonging to each high-speed transmission link. Subsequently, on each high-speed transmission link on each chip, different and regular numbers of PRBS test packets are started to be sent. The receiving end of the opposite link checks whether there are error bits, and determines whether the number of received PRBS test packets (rx_prbs_packets) is consistent with the expected number of received packets (rx_expect_prbs_packets). If there are error bits, it indicates that the cable connection quality is poor, and the construction personnel need to check the cable path quality. If there are no error bits and the number of received PRBS test packets (rx_prbs_packets) is consistent with the expected number of received packets (rx_expect_prbs_packets), it indicates that the cable connection is correct. If there are no error bits but the number of received PRBS test packets (rx_prbs_packets) is inconsistent with the expected number of received packets (rx_expect_prbs_packets), it indicates that the cable connection is incorrect.

[0078] Next, Figure 5 Taking the example, the execution process of the cable mis-insertion prevention detection method provided in this embodiment is described again:

[0079] 1. The management node connects the high-speed transmission link related information and software rules in the database through the network topology, and sets and records the tx_prbs_packets and rx_expect_prbs_packets of each high-speed transmission link.

[0080] 2. The management node forwards the tx_prbs_packets and rx_expect_prbs_packets of each high-speed transmission link to the chip to which each high-speed transmission link belongs through the network.

[0081] 3. Each chip sets the tx_prbs_packets of each high-speed transmission link to the PRBS Tx Pattern Generator module of each high-speed transmission link.

[0082] 4. Each chip starts the PRBS packet test.

[0083] 5. Each chip starts timer T0, checks whether there are error bits received by each high-speed transmission link, and queries rx_prbs_packets of each link.

[0084] 6. If there is a bit error, the detection result is determined to be poor cable connection quality; if there is no bit error, and rx_prbs_packets is consistent with rx_expect_prbs_packets, the detection result is determined to be accurate cable connection; if there is no bit error, and rx_prbs_packets is inconsistent with rx_expect_prbs_packets, the detection result is determined to be incorrect cable connection.

[0085] In addition, after executing step 305, the management node performs cable misinsertion detection based on the number of PRBS test packets received and the verification results. If the detection result is determined to be an incorrect cable connection, the management node determines the business frame number, board number, chip number, and high-speed transmission link number corresponding to the incorrect cable based on the number of PRBS test packets received, tx_prbs_packets, and the network topology connection database.

[0086] That is to say, when it is determined that the cable connection is incorrect after executing step 305, the service frame number, board number, and chip number of the sending link to which it is incorrectly connected can be inferred based on the actual number of PRBS test packets received and the number of PRBS packets sent for each high-speed transmission link recorded in the network topology connection database of the management node. Then, the pair of cables with the incorrect connection can be displayed on the interface, and the user can be prompted with the specific number of the sending link to which the high-speed transmission link should be connected (such as the service frame number, board number, chip number, high-speed transmission link number, etc.).

[0087] According to the prompt information on the interface, construction workers can quickly check the location where the cables are inserted incorrectly and connect the cables accurately, which greatly saves labor costs.

[0088] In specific implementation, the process of determining the incorrect cable can be as follows: Figure 6 As shown in the figure, if rx_prbs_packets is inconsistent with rx_expect_prbs_packets, then:

[0089] 1. According to the characteristic that tx_prbs_packets should be equal to rx_prbs_packets, the management node uses rx_prbs_packets as a condition to search the network topology connection database to obtain the specific location of the sender of the connection error.

[0090] 2. According to the characteristic that tx_prbs_packets should be equal to rx_prbs_packets, the management node uses rx_expect_prbs_packets as a condition to search in the network topology connection database to obtain the specific location of the sender to be connected.

[0091] 3. The user is prompted through the interface of the sender location to which the high-speed transmission link should be connected, as well as the specific location where the current cable is incorrectly plugged in.

[0092] The cable misplug detection method provided in this embodiment can automatically detect the accuracy of cable connection, significantly reduce labor costs, and improve system flexibility and maintainability. It can solve the problem of cable connection errors caused by manual inspection in large-scale cable connection systems.

[0093] In specific implementation, the cable mis-insertion detection method provided in this embodiment can issue instructions through software to quickly confirm the cable connection accuracy of any node in a large parallel system, significantly reduce labor costs, and improve system flexibility and maintainability.

[0094] The present embodiment provides a cable misinsertion detection method, wherein the large-scale cable system detected by the method includes a management node and multiple service frames; wherein the management node is connected to all service frames for managing all service frame resources; each service frame has multiple boards, each board has multiple chips, and each chip is interconnected with other chips through multiple high-speed transmission links; the method includes: the management node determines the number of PRBS test packets sent tx_prbs_packets and the expected number of PRBS test packets received rx_expect_prbs_packets for each high-speed transmission link; the management node sends tx_prbs_packets and rx_expect_prbs_packets to each chip belonging to each high-speed transmission link; the management node controls the controller belonging to each high-speed transmission link of each chip to generate tx_prbs_packets PRBS test packets, and transmits the PRBS test packets to the receiving side through the cable; the management node controls the controller belonging to the receiving side to verify the received PRBS test packets; the management node performs cable misinsertion detection according to the number of PRBS test packets received and the verification result. The method provided in this embodiment can detect the accuracy of cable connection, reduce labor costs, and solve the problem of cable connection errors caused by manual inspection in a large-scale cable connection system.
