The first embodiment is as follows:
fig. 1 is a first flowchart illustrating a network topology management method according to an embodiment of the present application, where an execution subject of the method may be an expansion unit, and as shown in fig. 1, the network topology management method may include the following steps:
step S101, periodically acquiring first control word information sent by a distributed unit by taking first preset time as an interval, and determining corresponding first address information according to the first control word information.
In this embodiment, because the Remote Unit (RU) is allocated with an IP in a DHCP manner, which is not capable of locating a problem device, a control word may be used to determine corresponding address information, the Distributed Unit (DU) may obtain a device currently connected to the Distributed Unit and its own device information at a predetermined time interval, generate corresponding control word information according to the device information according to a predetermined rule, and the control word information is set up according to the device, so that the control word information generated between different devices is different, so that the control word information may be used as identity information of the device to be connected, that is, identity information of the extension Unit, that is, an ID of the extension Unit, and periodically send the obtained identity information to the extension Unit FHM RU, thereby prompting the extension Unit to periodically read the identity information, i.e. the control word information, to determine the address information corresponding to the extension unit, i.e. the first address information, i.e. the IP address of the extension unit. Wherein the extension unit can adopt a Fronthaul Multiplexer (FHM); the first preset time can be set according to the user requirement, and is generally set to be 1 second.
Specifically, the device information includes configuration information, a port number of a distributed unit, a cascade number of an expansion unit, current device identification information, and a device number of a remote unit, and the configuration information includes a basic configuration item and reservation information. It will be appreciated that the remote unit is numbered 0, since the connection between the distributed unit and the expansion unit described above does not involve a remote unit. The port number of the distributed unit is a port number of the current equipment connection, the distributed unit can support 7 ports, a topology structure is generally established by adopting 4 ports, and the port number can be set to be 1 to 7; the cascade number of the expansion unit is the cascade number of a certain expansion unit which is currently connected with the distributed unit, each port of the distributed unit can support 15 expansion units, one port of a general distributed unit corresponds to 4 expansion units, and the cascade number is 1 to 15; the current device identification information is used for identifying a device currently connected, for example, the identifier 1 is an extension unit, and the identifier 0 is a remote unit; the remote unit device number is a device number of a certain remote unit currently connected with an expansion unit, each expansion unit can support 15 remote units, a common expansion unit adopts 8 ports to connect the remote units, and the device number of the remote unit can be set to 1-15. The configuration information is configuration information when devices are connected, a basic configuration item included in the configuration information is corresponding configuration obtained by determining that a number of a certain unit adopts automatic configuration, or corresponding configuration adopting a fixed number, because the numbers of certain batches of devices used for the same purpose are the same, a fixed number represents each device of the batch, and the numbers corresponding to the basic configuration items are generally set to be configured for carrying out automatic configuration numbers, for example, an identifier 1 is an automatic configuration number, and an identifier 0 is a fixed number; the reserved information included in the configuration information is information that can be extended and supplemented when the device is connected, and if no information can be supplemented currently, the information needs to be reserved for subsequent additional extension, and the number is 0 when no information needs to be supplemented generally. If the control word information is a 16BIT value, the presentation manner of the control word information may be as shown in the following table:
the above table shows that the format of the control word information can be [ basic configuration item ] - [ distributed unit port number ] - [ extended unit cascade number ] - [ reserved information ] - [ current equipment identification information ] - [ remote unit equipment number ]; if the distributed unit is [0] - [000] - [0000] [000] - [0] - [0000], and the distributed unit is connected with the expansion unit, the first control word information generated by the port 1 of the distributed unit connected with the expansion unit with the cascade number of 1 is [0] - [001] - [0001] [000] - [1] - [0000 ]; if the extension unit with the cascade number of 1 is connected with the port 2, the first control word information generated by the port 2 of the distributed unit connected with the extension unit with the cascade number of 1 is [0] [002] [0001] [000] [1] [0000 ]. After the expansion unit receives the control word information sent by the distributed unit, the control word information can be used as the identity information of the expansion unit.
Optionally, after the device of the remote unit is powered on, a 32-bit ID number may be automatically generated according to its own identity information, where the device information according to the identity information may specifically correspond to that ID [31:24] corresponds to a port number of a distributed unit, and is generally arranged from 1; ID [23:16] corresponds to the cascade number of the expansion unit and is arranged from 1; ID [15:8] corresponds to the remote unit device number, starting with 1, and for the expansion unit itself, this field may be 0; ID [7:0] corresponds to the reservation information; the address of the above distributed unit is generally fixed to 0x 00000000.
Optionally, step S101 includes: acquiring an expansion unit cascade number and a distributed unit port number from the first control word information; and processing the port number of the distributed unit, and determining the first address information according to the cascade number of the expansion unit and the port number of the processed distributed unit.
Optionally, the processing the port number of the distributed unit includes: determining the cascade number of expansion units corresponding to one port of the distributed unit; calculating a product of the number of cascades and the distributed unit port number.
In this embodiment, the expansion unit cascade number and the distributed unit port number may be obtained from the first control word information, and the distributed unit port number is subjected to the most significant processing, that is, a maximum value is selected from all possible values of the expansion unit cascade number, a product of the selected maximum value and the distributed unit port number is calculated, a sum of the obtained distributed unit port number subjected to the most significant processing and the expansion unit cascade number is calculated, so that only one value representing the expansion unit may be obtained, and the first address information is determined by using the value, so as to obtain an address representing the expansion unit.
It can be understood that, considering that the address information is the only address information currently representing each unit, the address of each unit needs to be determined according to the unit connected with the unit and the address information itself, and the first control word information determination only relates to the connection between the distributed unit and the expansion unit, and does not determine whether there is a remote unit connected subsequently, and there may be a new connection of the remote unit, so the address of the expansion unit can be determined according to the distributed unit, the expansion unit and the related device information, and if the port number of the distributed unit and the cascade number of the expansion unit are calculated separately, the same value may appear, for example, the port of the port number 1 of the distributed unit is connected with the expansion unit of the cascade number 2 of the expansion unit, the port of the port number 2 of the distributed unit is connected with the expansion unit of the cascade number 1 of the expansion unit, the values obtained after the connection between the two units are consistent, which results in consistent address information of the two units, and therefore, the port numbers of the distributed units need to be subjected to the most valued processing.
As a specific example and not by way of limitation, if the IP of the current distributed unit is "192.168.0.3" and the subnet mask is "255.255.0.0", the last two fields of the IP of the extended unit may be changed, and the current distributed unit port number is a, the extended unit cascade number is B, and the maximum value of the current distributed unit port number is 15, then the above means is used to calculate the formula S being a × 15+ B, and the result S is placed in the third field of the IP of the extended unit. Since the current device identification information in the first control word information can be known as the expansion unit of the currently determined address information, the current overall structure does not consider the remote unit, so that the fourth field of the IP of the current expansion unit does not need to consider the remote unit, the fourth field of the IP of the expansion unit can be set according to the user requirement, for example, 16, and when the fourth field of the IP of the expansion unit takes the value of 16, the IP of the processed expansion unit is 192.168. s.16. For example, if the first control word information received by the current expansion unit is [0] [001] [0001] [000] [1] [0000], the IP of the corresponding expansion unit is "192.168.16.16".
Step S102, obtaining the device information corresponding to the expansion unit, and changing the first control word information according to the device information corresponding to the expansion unit by a preset rule to obtain second control word information.
In this embodiment, the extension unit may obtain the device information corresponding to the connection between the remote unit and the current extension unit, so as to change some information, which does not conform to the connection between the current devices, in the first control word information according to the obtained device information by using a preset rule, thereby obtaining the second control word information, that is, the identity information of the remote unit to which the current extension unit is connected.
It can be understood that, since the extension unit needs to acquire the current device information connected to the remote unit to change the first control word information, it needs to acquire the device number of the remote unit, and change the current device identification information in the device information to generate the corresponding second control word information, which corresponds to the remote unit.
As a specific example and not by way of limitation, it can be seen from the foregoing embodiment that the format of the control word information is [ basic configuration item ] - [ distributed unit port number ] - [ extended unit cascade number ] - [ reserved information ] - [ current device identification information ] - [ remote unit device number ]; if the first control word information received by the expansion unit is [0] - [001] - [0001] - [000] - [1] - [0000], and the number of the remote unit equipment connected with the expansion unit is 1, the second control word information is [0] - [001] - [0001] - [000] - [0] - [0001 ]; if the remote unit device number connected to it is 2, the second control word information is [0] - [001] - [0001] - [000] - [0] - [0002]. After the remote unit receives the control word information sent by the expansion unit, the control word information can be used as the identity information of the remote unit.
Step S103, sending the second control word information to a remote unit, so that the remote unit determines corresponding second address information according to the second control word information.
In this embodiment, after the distributed unit processes the second control word information, the second control word information is sent to the remote unit connected to the distributed unit, where the second control word information is identity information of the remote unit, so as to prompt the remote unit to periodically read the second control word information, and further determine corresponding address information, that is, the second address information, that is, an IP address of the remote unit, according to the second control word information.
It can be understood that, since the second control word information is determined based on the connection between the distributed unit and the expansion unit, the device information corresponding to the remote unit is determined, so that the port number of the distributed unit, the cascade number of the expansion unit, and the device number of the remote unit need to be obtained from the second control word information, and the second address information is determined according to the obtained information.
As a specific example and not by way of limitation, if the IP of the current distributed unit is "192.168.0.3" and the subnet mask is "255.255.0.0", the last two fields of the IP of the extended unit may be modified, and if the port number of the current distributed unit is a, the cascade number of the extended unit is B, the device number of the remote unit is C, and the maximum value of the port number of the current distributed unit is 15, then the third field of the IP of the remote unit is obtained according to the formula S × 15+ B. Since it can be known from the current device identification information in the second control word information that the current address information is determined to be the remote unit, the fourth field of the IP of the current extension unit needs to consider the remote unit, and can be set according to the device number C of the remote unit, so the IP of the processed extension unit is "192.168. s.c". If the second control word information received by the current remote unit is [0] - [001] - [0001] - [000] - [0] - [0001], the IP of the corresponding remote unit is "192.168.16.1"; if the second control word information received by the current remote unit is [0] [001] [0001] [000] [0] [0002], the IP of the corresponding remote unit is "192.168.16.2".
Optionally, the extension unit may send the second control word information to a sub-extension unit connected thereto, so that the sub-extension unit determines corresponding second address information according to the second control word information, for example, if the first control word information received by the extension unit is [0] [001] [0001] [000] [1] [0000], and the extension unit device number connected thereto is 2, the second control word information is [0] [001] [0002] [000] [1] [0000], and the IP of the corresponding extension unit is "192.168.17.16". The expansion unit and the sub-expansion unit are only used for distinguishing descriptions.
And step S104, constructing a topological structure according to the first address information and the second address information.
In this embodiment, by setting address information step by step between the above-mentioned devices, address information of each unit directly or indirectly connected to the distributed unit at present may be determined, and then a topology structure currently including connection statuses of all the devices may be constructed according to the address information of each step of unit, as shown in fig. 2, fig. 2 is a topology structure diagram of the network topology management method provided in this embodiment, where the topology structure diagram includes a distributed unit DU, an extended unit or extended subunit FHM RU, and a remote unit RU.
Optionally, step S104 includes: and periodically sending heartbeat information to the distributed units at intervals of second preset time so that the distributed units construct the expansion units into the topological structure according to the first address information in the heartbeat information.
In this embodiment, after determining the corresponding first address information, the extension unit sends heartbeat information to the distributed unit periodically at intervals of a second preset time, and after receiving the heartbeat information, the distributed unit forms a topology tree according to the first address information carried in the heartbeat information, that is, the corresponding extension unit is built into the topology structure. Wherein, the second preset time may be set to 2 seconds.
Optionally, the heartbeat information includes identity information of a corresponding expansion unit.
Optionally, a User Datagram Protocol (UDP) Server is established in the distributed unit, the UDP Server may monitor a specific port and address information of a distributed unit, the specific port is configured to receive data information sent by an extension unit or a remote unit connected to the distributed unit, and a monitoring module UDP Client is established in each extension unit and remote unit connected to the distributed unit, so as to perform the heartbeat mechanism. When the physical connection port is changed, the address information will be changed, and the established UDP Client will also be changed, and the UDP Client will perform the operations of deleting and re-establishing.
Optionally, as shown in fig. 3, fig. 3 is a second flowchart of the network topology management method provided in the embodiment of the present application, and includes:
step S301, if there is a connection operation performed by the current remote unit, acquiring device information corresponding to the current remote unit.
Step S302, changing the first control word information according to the equipment information corresponding to the current remote unit by a preset rule to obtain third control word information.
Step S303, sending the third control word information to the current remote unit, so that the current remote unit determines corresponding third address information according to the third control word information.
In this embodiment, if there is a connection operation performed by the current remote unit, which indicates that a new device is currently inserted, the device information corresponding to the current remote unit is obtained, so that the extension unit modifies the first control word information according to the corresponding device information to obtain third control word information, and sends the third control word information to the current remote unit, so that the current remote unit determines corresponding third address information according to the third control word information, and establishes a monitoring module UDP Client, so as to periodically send heartbeat information to the distributed unit at intervals of a second preset time, when the distributed unit first obtains heartbeat information sent by the current remote unit, the distributed unit constructs the current remote unit into a topology structure according to the third address information in the heartbeat information, records the time when the current remote unit sends the heartbeat information, and performs an alarm prompt, and the network staff is reminded to judge whether the requirement is met by newly added equipment in the current topological structure.
In the embodiment of the application, first control word information sent by a distributed unit is periodically acquired at intervals of a first preset time, and corresponding first address information is determined according to the first control word information; acquiring device information corresponding to the expansion unit, and changing the first control word information according to the device information corresponding to the expansion unit by a preset rule to obtain second control word information; sending the second control word information to a remote unit so that the remote unit determines corresponding second address information according to the second control word information; and constructing a topological structure according to the first address information and the second address information, determining corresponding address information by using the control words, and setting step by step to further form the topological structure, so that when the equipment has problems, a network administrator can accurately position the problem equipment through the corresponding control words, and the efficiency of the network administrator in managing the problem equipment is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
Example two:
fig. 4 is a schematic diagram illustrating a third flow of a network topology management method according to an embodiment of the present application, where an execution subject of the method may be a distributed unit, and as shown in fig. 4, the network topology management method may include the following steps:
step S401, periodically acquiring heartbeat information at intervals of a second preset time.
Step S402, if the current topological structure does not have the remote unit corresponding to the heartbeat information, the remote unit is built into the topological structure, and alarm reminding is carried out.
In this embodiment, after periodically acquiring heartbeat information sent by a remote unit at intervals of second preset time, a distributed unit searches for the remote unit corresponding to the heartbeat information, and if the corresponding remote unit is found in the current topological structure, records the time when the heartbeat information is received to a corresponding position of the topological structure, and updates the time, so as to update the time stamp of the corresponding unit in the topological structure to the current recording time; if the corresponding remote unit is not found in the current topological structure, the remote unit which is not found is built into the topological structure, the time of receiving the heartbeat message is recorded to the corresponding position of the topological structure, and alarm reminding is carried out to remind network staff and newly added equipment in the current topological structure to judge whether the requirement is met. Wherein the second preset time is 2 seconds.
Optionally, the distributed unit may further obtain heartbeat information of the expansion unit or the sub-expansion unit periodically at intervals of a second preset time; and if the current topological structure does not have the expansion unit or the sub-expansion unit corresponding to the heartbeat information, constructing the expansion unit or the sub-expansion unit into the topological structure, and alarming and reminding.
Optionally, as shown in fig. 5, fig. 5 is a fourth flowchart illustrating a network topology management method provided in the embodiment of the present application, where the fourth flowchart includes:
step S501, periodically acquiring time stamps of all remote units in the topological structure at intervals of third preset time; the timestamp is the time when the heartbeat information sent by the remote unit for the last time is received.
Step S502, obtaining the current time, and calculating the time difference between the timestamp and the current time.
And S503, when the time difference is larger than a preset time threshold, deleting the corresponding remote unit in the topological structure, and alarming and reminding.
In this embodiment, since there is a possibility that a certain remote device is suddenly powered off, a network is dropped, or removed, the distributed unit sets a detection mechanism, that is, the timestamp of each remote unit in the topology structure is periodically obtained at intervals of a third preset time, where the timestamp is a time when the remote unit receives the last heartbeat information sent by the remote unit. If the remote units have problems or are removed, the corresponding heartbeat messages cannot be sent to the distributed units, so that judgment is carried out according to the time when each remote unit sends the heartbeat messages for the last time, the time difference value between the current detection moment and the timestamp is calculated, if the time difference value is larger than a preset time threshold value, the current remote equipment has problems or is removed, the corresponding remote units in the topological structure are deleted, and alarm reminding is carried out, so that network workers can confirm the remote equipment. Wherein the third preset time is 0.5 second, and the time threshold is 3 seconds.
Optionally, the distributed unit may further detect a timestamp of the expansion unit or the sub-expansion unit by using a detection mechanism, and perform a relevant judgment, so as to determine a relevant problem of the expansion unit or the sub-expansion unit and update the topology structure in time.
In the embodiment of the application, heartbeat information is periodically acquired at intervals of second preset time; and if the current topological structure does not have the remote unit corresponding to the heartbeat information, constructing the remote unit into the topological structure, and alarming and reminding. The distributed unit periodically acquires heartbeat information of the current topological structure to update the topological structure, and simultaneously carries out alarm reminding to remind network workers, new equipment appears in the current topological structure, and therefore the efficiency of a network administrator in managing problem equipment is improved.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
