1. Standing book
The original account book is placed on the desk for people to read. The standing book currently includes information such as files, work plans, work reports and the like.
The routing ledger table in the present disclosure is a ledger table in which port connection relationship information between network devices as shown in fig. 2 is recorded. Wherein a first network device 201 is deployed in a machine room a, and a second network device 202 is deployed in a machine room B.

Figure BDA0004037893930000071
After the device port is regulated according to service requirements, the routing ledger table is required to be updated, but because the ledger table is updated and carded by different departments and the updating and carding modes of the ledgers are different for each person, the accuracy of the updated routing ledger table is difficult to guarantee.
2. Link layer discovery protocol LLDP
At present, network devices are increasingly various and are complicated in configuration, and in order to enable devices of different manufacturers to discover and interact with each other in a network, a standard information exchange platform is required.
The link layer discovery protocol (Link Layer Discovery Protocol, LLDP) is generated in such a background, and provides a standard link layer discovery manner, so that the information such as the main capability, management address, device identifier, interface identifier and the like of the local terminal device can be organized into different TLVs (types/Length/values), and the different TLVs are encapsulated in the LLDPDU (Link Layer Discovery Protocol Data Unit ) to be issued to the neighboring device in the form of an LLDP message, and the neighboring device can be stored in the form of a standard MIB (Management Information Base ) after receiving the information, so as to be used by the network management system for inquiring and judging the communication condition of the link.
LLDP message
The packet encapsulated with the LLDPDU is called an LLDP packet, and has two encapsulation formats, i.e., ethernet II and SNAP (Subnetwork Access Protocol, subnet access protocol).
Transmission mechanism: when the port is operated, the device periodically transmits an LLDP message to the neighboring device. And if the local configuration of the equipment changes, immediately sending an LLDP message to inform the adjacent equipment of the change condition of the local information as soon as possible. However, in order to prevent the frequent change of the local information from causing a large amount of sending of the LLDP messages, each time an LLDP message is sent, it is necessary to delay a period of time before continuing to send the next message. When the device discovers a new adjacent device, i.e. receives a new LLDP message and the local device does not store the information of the device for transmitting the message yet, the device automatically starts a quick transmission mechanism, shortens the transmission period of the LLDP message to 1 second, continuously transmits a designated number of LLDP messages and then returns to a normal transmission period.
Reception mechanism: when the port works, the device checks the validity of the received LLDP message and the TLV protocol carried by the LLDP message, and stores neighbor information to the local after checking.
Illustratively, as shown in fig. 3, the fourth network device 302 sends an LLDP message to port 1 of the third network device 301 via port 3. Accordingly, the third network device 301 receives, through the port 1, the LLDP packet sent by the fourth network device 302 through the port 3.
The third network device 301 sends an LLDP message to port 4 of the fourth network device 302 via port 2. Accordingly, the fourth network device 302 receives the LLDP message from the third network device 301 via port 2 via port 4.
The fifth network device 303 transmits an LLDP message to port 5 of the fourth network device 302 via port 8. Accordingly, the fourth network device 302 receives the LLDP message sent by the fifth network device 303 through the port 8 through the port 5.
The fourth network device 302 transmits an LLDP message to port 7 of the fifth network device 303 through port 6. Accordingly, the fifth network device 303 receives the LLDP message sent by the fourth network device 302 through the port 6 through the port 7.
The sixth network device 304 transmits an LLDP message to the port 10 of the fifth network device 303 through the port 12. Accordingly, the fourth network device 303 receives the LLDP message sent by the fifth network device 303 through the port 12 through the port 10.
The fifth network device 303 transmits an LLDP message to the port 11 of the sixth network device 304 through the port 9. Accordingly, the sixth network device 304 receives the LLDP message sent by the fifth network device 303 through the port 9 through the port 11.
Based on the message transmission situation that the network devices mutually transmit the LLDP message, it can be determined that the third network device 301 has an adjacency relationship with the fourth network device 302, the fourth network device 302 has an adjacency relationship with the third network device 301 and the fifth network device 303, the fifth network device 303 has a connection relationship with the fourth network device 302 and the sixth network device 304, and the sixth network device 304 has an adjacency relationship with the fifth network device 303.
3. Flow rate waveform diagram
The first flow rate waveform diagram in the present disclosure is used to characterize the flow rate of the port of the target device within the preset time period, and the second flow rate waveform diagram is used to characterize the flow rate of the port of the adjacent device of the target device within the preset time period.
Illustratively, as shown in fig. 4, wherein the first traffic rate waveform is the port traffic transmission rate of the target device and the second traffic rate waveform is the port traffic reception rate of the neighboring device of the target device. And determining the connection relation between the port of the target device and the port of the adjacent device according to the similarity between the first flow chart and the second flow chart.
In the current scenario of device port management, after the device port is adjusted according to the service requirement, the route ledger table recording device and the identification information and the position information of the port thereof need to be updated. However, since the information in the routing table relates to a plurality of departments, people of different departments are required to update the routing table together, and the updating and carding modes of the routing table of each person are different, so that the accuracy of the data recorded by the routing table is difficult to guarantee.
In order to solve the technical problems in the related art, the present disclosure provides a port connection detection method, where a port connection detection apparatus determines, according to an LLDP packet, an adjacent device of a target device, that is, determines an adjacent relationship between devices. After the adjacent equipment of the target equipment is determined, the flow rates of all ports of the target equipment and the adjacent equipment in a preset time period are called, and the ports connected with the target equipment and the adjacent equipment are determined according to the flow rates of all the ports, so that the connection relation between the ports is accurately determined.
As shown in fig. 5, fig. 5 is a diagram illustrating a port connection detection method according to an embodiment of the present disclosure, for determining a connection relationship between ports of a device, where the method includes the following steps S501 to S504.
S501, the port connection detection device acquires the LLDP message of the target device.
Wherein the target device comprises at least one first port. The LLDP message includes an identification of the target device's neighboring devices.
It is understood that the target device supports and enables devices of the LLDP protocol.
Illustratively, the target device may be a router, and the LLDP message includes at least one of: the management address of the router, the device identification of the router, and the router port identification.
S502, the port connection detection device determines at least one adjacent device of the target device according to the LLDP message.
Wherein each of the at least one adjoining device comprises at least one second port.
It can be understood that the adjacent device is a device supporting and enabling the LLDP protocol, because the target device can only receive the LLDP message transmitted by the device having an adjacency relationship with the target device, the adjacent device of the target device can be confirmed based on the LLDP message.
The adjacency device may be an OTN device, and the port connection detecting apparatus may determine that the router has an adjacency relationship with the OTN device according to an identifier of the OTN device in the LLDP packet.
S503, the port connection detection device acquires a first flow rate of each first port in a preset time period and a second flow rate of each second port in the preset time period.
In a possible implementation manner, the port connection detection device determines, according to data provided by the network management system, a traffic rate of each port of the router and a traffic rate of each port of the OTN device adjacent to the router in a preset period of time.
S504, the port connection detection device determines a target second port connected with each first port according to the first flow rate and the second flow rate.
Optionally, the first flow rate is a sending rate of each flow corresponding to each port of the router in a preset time period, and the second flow rate is a receiving rate of each flow corresponding to each port of the OTN device in the preset time period.
In a possible implementation manner, the port connection detection device determines a connection relationship between a port of the router and a port of the OTN device according to each flow sending rate corresponding to each port of the router in a preset time period and each flow receiving rate corresponding to each port of the OTN device in the preset time period.
The technical scheme provided by the embodiment at least has the following beneficial effects: the port connection detecting means determines the adjacent devices of the target device, that is, confirms the adjacent relationship between the devices, based on the LLDP message stored in the MIB. After the adjacent equipment of the target equipment is determined, the flow rates of all ports of the target equipment and the adjacent equipment in a preset time period are called, and the connection relation between the ports is accurately determined according to the comparison flow rates.
In a possible implementation manner, as shown in fig. 6 in conjunction with fig. 5, the above-mentioned step S501 of the port connection detecting apparatus obtaining the link layer discovery protocol LLDP message in the target device specifically includes the following steps S601-S603, which are described in detail below.
S601, the port connection detection device receives an LLDP message from the target device.
In a possible implementation manner, the OTN device generates an LLDP packet according to its device location information and port connection information, and sends the LLDP packet to an adjacent router. And after receiving the LLDP message sent by the OTN equipment, the adjacent router sends the LLDP message to the port connection detection device.
S602, the port connection detection device stores the LLDP message of the target device into the MIB.
In one possible implementation manner, the port connection detecting device determines an association relationship between an LLDP message and a router after receiving the LLDP message from the router, and stores the LLDP message in the MIB.
S603, the port connection detection device acquires the LLDP message of the target device from the MIB after receiving the first operation instruction.
The first operation instruction is used for indicating to determine port connection information of the target device.
Illustratively, when the operator needs to update the router ledger, a first instruction for instructing to determine port connection information of the target device is input to the port connection detection apparatus. After receiving the first operation instruction, the port connection detection device acquires an LLDP message of the target device from the MIB, executes the port connection detection method described in the application, determines the port connection relation between the router and the OTN device, and updates the router ledger according to the connection relation.
The technical scheme provided by the embodiment at least has the following beneficial effects: after receiving the LLDP message from the adjacent device, the target device sends the LLDP message to the port connection detection device, the port connection detection device stores the LLDP message in the MIB library, and after receiving the instruction for determining the port connection information of the target device, the port connection detection device can directly acquire the LLDP message from the MIB library, so that the port connection detection device determines the port connection information of the target device according to the LLDP message.
In a possible implementation manner, the first flow rate is specifically a first flow rate waveform chart, and the second flow rate is specifically a second flow rate waveform chart, where the flow rate waveform chart is used to characterize the flow rate at a plurality of time points within a preset time period.
In a possible implementation manner, as shown in fig. 7, the port connection detection apparatus in S504 may perform a target operation on each of the first ports, and determine a target second port to which each of the first ports is connected.
The target operation specifically includes S701 to S703, which will be described in detail below.
S701, the port connection detection device determines a first flow rate waveform diagram of the target first port.
In a possible implementation manner, the port connection device may acquire, through the network management system, a traffic rate waveform diagram of all ports of the target device in a preset time period, and a traffic rate waveform diagram of all ports of an adjacent device of the target device in the preset time period.
