Description

Technical Field

[0001] This application relates to the field of network communication technology, and in particular to a network scheduling method, apparatus, computer equipment, computer-readable storage medium, computer program product, and system. Background Technology

[0002] In optical transmission networks, the OCS (Optical Cross-Connect) device, acting as a pure optical cross-connect system, only possesses optical signal switching capabilities and does not carry optical modules. Optical modules are deployed on the network layer devices at both ends to perform photoelectric conversion. When establishing an optical transmission network, the OCS device relies on manually entering the "cross-connect port - optical module port" mapping to build the topology table, and cannot proactively perceive the status of optical modules. This makes the network topology opaque to the OCS device, resulting in low efficiency in topology recognition. When optical modules are plugged in or removed, or ports are changed, the network topology table must be manually reconfigured, which is time-consuming, labor-intensive, and prone to errors.

[0064] First, a definition of the terminology used in this application is provided:

[0065] OCS (Optical Circuit Switch): A pure optical layer switching device that enables direct switching and routing of optical signals between different ports through an optical cross-connect matrix.

[0066] Optical cross-connect matrix: A functional component of an OCS device used to realize physical layer cross-connection and routing scheduling of optical signals between different input and output ports.

[0067] Network layer devices: Hardware carriers for deploying optical modules, including switches, routers, OTN terminals, etc.

[0068] Optical module: An optoelectronic conversion device deployed on network layer equipment to realize the mutual conversion between electrical signals and optical signals.

[0069] EEPROM: Electrically Erasable Programmable Read-Only Memory, a type of non-volatile memory that allows data to be repeatedly erased and written via electrical signals.

[0070] SFP (Small Form-factor Pluggable): A compact, hot-pluggable optical transceiver module used to convert between electrical and optical signals.

[0071] QSFP (Quad Small Form-factor Pluggable): A compact, hot-pluggable optical module packaging standard that supports four channels of high-speed data transmission.

[0072] Topology: The overall structural layout of network devices and their connections, including the connection mapping between the cross-connect ports of the OCS device and the optical module ports on the network layer devices at both ends.

[0073] Optical transmission network: a high-speed communication network that uses optical fiber as the transmission medium and optical signals as the information carrier.

[0074] AES (Advanced Encryption Standard): A symmetric block cipher algorithm that uses 128-bit block lengths and encrypts data through a multi-round substitution-permutation network.

[0075] I2C (Inter-Integrated Circuit): A serial, half-duplex, multi-master, multi-slave short-distance communication interface that enables bidirectional data transmission between devices through two signal lines: SDA (serial data line) and SCL (serial clock line).

[0076] OTN (Optical Transport Network) terminal: A network layer device based on optical transport network technology, used to realize the mutual conversion between electrical signals and optical signals.

[0077] Switch: A network layer device that operates at the data link layer or network layer of the OSI model. It forwards data packets from the source port to the destination port by parsing the MAC address or IP address in the data frame.

[0078] Router: A network layer device used to forward data packets between different networks. It determines the optimal path for data forwarding by querying a routing table, thereby enabling network interconnection and communication.

[0079] CRC (Cyclic Redundancy Check): An error detection technique based on polynomial division. It generates a fixed-length check code by performing modulo-2 division on the data and appends it to the data. The receiver verifies the data using the same algorithm. If the remainder is not zero, it is determined that there is an error in the transmission.

[0080] Secondly, to facilitate understanding of the technical solutions provided in the embodiments of this application by those skilled in the art, the relevant technologies are described below:

[0081] Optical Controllers (OCS) are the core scheduling devices in optical transmission networks, primarily responsible for cross-connection, routing scheduling, and resource allocation of optical paths at the optical layer. The OCS itself only has the capability to switch and combine optical signals and does not carry optical modules. The core component of photoelectric conversion—the optical module—is deployed on network layer devices (such as routers, OTN terminals, or switches) at both ends of the OCS to support the connection of optical links.

[0082] However, due to the physical separation of OCS and optical modules, OCS relies primarily on manual configuration and static synchronization with external network management systems for topology awareness and link adjustment. This leads to frequent manual reconfiguration when port changes, plugging / unplugging, or device migration occur, which is not only time-consuming and labor-intensive but also prone to port correspondence errors or information omissions, resulting in scheduling mistakes. Furthermore, in the event of optical module failure or link interruption, maintenance personnel must manually check the status of both ends before issuing cross-connection commands. This manual intervention mode typically results in response times in the minute range. Moreover, although optical modules have built-in writable storage areas such as EEPROM, they currently only store basic hardware information such as manufacturer and wavelength, not related to the topology management requirements of OCS, preventing the optical modules from providing effective topology awareness support for OCS. Furthermore, because OCS cannot actively obtain the real-time status of the optical modules at both ends (such as failure or offline status), it struggles to identify topology anomalies when optical modules malfunction, easily leading to hidden faults such as "internal cross-connection normal but actual optical path not working."

[0083] Therefore, this application provides a network scheduling technical solution. In this technical solution, (1) the scheduling device automatically recognizes the network topology by using the topology feature code pre-stored in the optical module, which improves the transparency of the network topology to the scheduling device and the efficiency of the scheduling device in recognizing the network topology, and also improves the utilization rate of the storage resources in the optical module; (2) the automatically generated target topology table enables the scheduling device to grasp the relationship between optical modules in real time, thereby realizing the dynamic adjustment of the network, improving the response speed of network adjustment and the reliability of the network; (3) by monitoring the status flag of the optical module in real time and combining the optical path priority to switch the second optical path to update the target topology table, the connection action of the backup optical module and the logical topology record are linked in real time, thereby improving the efficiency of automated processing from anomaly detection to link reconstruction and the consistency of topology status while prioritizing the continuity of high-priority services; (4) the connection of the first target optical module and the second target optical module is realized according to the service scheduling command, which improves the flexibility and automation of network scheduling, shortens the response cycle of network scheduling, and ensures the accuracy and consistency of topology information in network scheduling. See the following text for details.

[0084] Finally, for ease of understanding, an exemplary operating environment is provided below.

[0085] like Figure 1 As shown in the diagram, the operating environment includes: scheduling device 2, network layer devices (4A and 4B), and control terminal 6.

[0086] Dispatching device 2 can connect to network layer devices 4A and 4B via optical links. Dispatching device 2 can be a single optical cross-connect device (such as an OCS device). Dispatching device 2 can provide optical cross-connect services to network layer devices. Dispatching device 2 can provide services via an optical transmission network. The optical transmission network includes various optical network devices, such as optical amplifiers, dispersion compensators, optical add-drop multiplexers (OADMs), optical cross-connectors, optical terminal multiplexers, optical line protection devices, etc. The optical transmission network can include physical optical links, such as single-mode fiber links, multimode fiber links, fiber bundle links, and combinations thereof, or wireless optical links, such as free-space optical communication (FSO) links.

[0087] Network layer devices (4A and 4B) can be configured to interact with scheduling device 2 for optical signal exchange and service data transmission. Network layer devices 4A and 4B may include hardware carriers for deploying optical modules, such as routers, switches, OTN terminals, WDM terminals, etc., and may also include virtualized network function instances. Network layer devices (4A and 4B) include optical modules, which may have built-in writable storage areas (such as EEPROM) for storing topology signatures, etc.

[0088] Control terminal 6 can be a single computer, a network management terminal, a network management server cluster, or a network management cloud platform, etc. Control terminal 6 can communicate with scheduling device 2 and network layer devices (4A and 4B) via the management network. Control terminal 6 can be used to visually display the topology table, optical module status information, and adjustment records of scheduling device 2, issue service scheduling commands, and receive alarm information from scheduling device 2, etc. Control terminal 6 may also include a coding module for writing and updating topology feature codes to the optical modules on network layer devices 4A and 4B, etc.

[0089] It should be noted that the above-mentioned equipment is exemplary, and the number and type of equipment can be adjusted in different scenarios or according to different needs.

[0090] The technical solutions of this application are described below through several embodiments. It should be understood that these embodiments can be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0091] Example 1

[0092] This method embodiment can be executed in a scheduling device, which is used to connect the first optical module and the second optical module. The scheduling device will be considered the single execution entity in this process below.

[0093] Figure 2 A flowchart illustrating a network scheduling method according to Embodiment 1 of this application is shown.

[0094] like Figure 2 As shown, the network scheduling method may include steps S200~S204, wherein:

[0095] Step S200: Obtain the first topology feature code in the first optical module and the second topology feature code in the second optical module; the first topology feature code includes a field describing the connection method between the scheduling device and the first optical module; the second topology feature code includes a field describing the connection method between the scheduling device and the second optical module.

[0096] Step S202: Generate a target topology table based on the first topology feature code and the second topology feature code.

[0097] Step S204: Connect the first optical module and the second optical module according to the target topology table.

[0098] The network scheduling method provided in this embodiment involves a scheduling device obtaining network connection methods from topology feature codes pre-stored in optical modules to construct a target topology table, thereby achieving optical path scheduling. By using the topology feature codes pre-stored in the optical modules, the scheduling device automatically recognizes the network topology, improving the transparency of the network topology to the scheduling device and the efficiency of the scheduling device's network topology recognition, as well as increasing the utilization rate of storage resources in the optical modules. Simultaneously, the automatically generated target topology table allows the scheduling device to grasp the relationships between optical modules in real time, thereby enabling dynamic network adjustments and improving the response speed and reliability of network adjustments. Furthermore, this embodiment can achieve network scheduling without changing the hardware architecture of the network scheduling system, only expanding the write code content stored in the optical modules, using the topology feature codes in the expanded write code content to achieve network scheduling, improving the versatility of the network scheduling method and reducing application costs.

[0099] The following combination Figure 2 The steps in steps S200 to S204, as well as other optional steps, are described in detail.

[0100] Step S200 The system obtains a first topology feature code from the first optical module and a second topology feature code from the second optical module. The first topology feature code includes a field describing the connection method between the scheduling device and the first optical module. The second topology feature code includes a field describing the connection method between the scheduling device and the second optical module.

[0101] The scheduling device can be an OCS (Optical Server System), and the first and second optical modules can be SFP (Optical Prefix) or QSFP (Optical Standard Prefix) optical modules deployed on network layer devices (such as OTN terminals) at both ends of the OCS. The scheduling device and the optical modules can be connected via integrated I2C and Ethernet communication interfaces. The optical modules can send information such as topology feature codes encrypted using methods such as AES to the scheduling device through these interfaces. In some embodiments, the scheduling device can also automatically trigger the acquisition of topology feature codes (including the first and second topology feature codes) in the optical modules (including the first and second optical modules) when powered on, hot-plugged, or when the network is established. In other embodiments, the scheduling device can also poll and read the topology feature codes in the optical modules at preset time intervals (such as 100 milliseconds, 1 second, etc.). The scheduling device can read the complete topology feature code each time it reads, or it can only read the complete topology feature code when a change in the version number or a specific identifier bit of the topology feature code is detected, and only read the version number or specific identifier bit when no change is detected.

[0102] The topology signature includes data written to and stored in the writable storage area of ​​the optical module, used to characterize the connection method between the optical module and the scheduling device, and / or the connection method between the peer optical module and the scheduling device. In some embodiments, the topology signature can be stored in a reserved extended address segment of the built-in memory (such as EEPROM) of the corresponding optical module. The connection method between the optical module and the scheduling device can be recorded in the topology signature through fields such as the device identifier of the network layer device to which the optical module belongs, the port location of the optical module on the network layer device, the port number connected to the optical module on the scheduling device, and the topology information of the peer optical module. In some embodiments, the topology signature may also include several additional information fields, such as the real-time status identifier of the optical module.

[0103] In this embodiment, by pre-storing topology feature codes containing connection method fields in the optical module, the scheduling device can proactively perceive the topology relationships in the network, improving the accuracy and efficiency of the scheduling device in topology cognition, enhancing the transparency and precision of the scheduling device in topology management, and also improving the utilization rate of storage resources in the optical module.

[0104] As mentioned earlier, topological feature codes can record corresponding connection methods through various field combinations. The following provides an example field combination in a topological feature code.

[0105] In an optional embodiment, the first optical module is deployed on a first network layer device, and the second optical module is deployed on a second network layer device. The first topology feature code includes: the device identifier of the first network layer device, the port identifier of the first optical module on the first network layer device, the port identifier associated with the first optical module on the scheduling device, and connection information between the second optical module and the scheduling device. The second topology feature code includes: the device identifier of the second network layer device, the port identifier of the second optical module on the second network layer device, the port identifier associated with the second optical module on the scheduling device, and connection information between the first optical module and the scheduling device.

[0106] Network layer devices (e.g., first network layer device, second network layer device) can be routers or OTN terminals, and the device identifier of a network layer device can be its serial number (SN). In some embodiments, the connection information between the second optical module and the scheduling device may include the device identifier of the second network layer device, the port identifier of the second optical module on the second network layer device, and the port identifier associated with the second optical module on the scheduling device. Similarly, the connection information between the first optical module and the scheduling device can also be set accordingly. It should be noted that the length of each field in the topology feature code can be adjusted according to actual needs.

[0107] Step S202 Based on the first topological feature code and the second topological feature code, a target topology table is generated.

[0108] The target topology table may include a structured data table generated by the scheduling device based on the topology feature codes of one or more optical modules, used to record the association relationships between network layer devices, optical module ports, and scheduling device ports. The scheduling device can generate the target topology table by extracting the connection methods (including optical module device number, port number, etc.) between the optical modules and the scheduling device from the topology feature codes. In some embodiments, the topology feature codes may also include fields describing the connection methods between the peer optical modules and the scheduling device. Before generating the target topology table, the scheduling device may first compare the consistency of the field information in the optical modules at both ends, and only generate the target topology table if consistency is determined. The generated target topology table may be stored in the local cache of the scheduling device and in a network management or control terminal outside the network. The target topology table stored in the local cache or other locations may also be updated by triggering specific conditions. When stored in a network management or control terminal, the target topology table may also be converted into a visual data form (such as a topology map) for visualization.

[0109] In this embodiment, the distributed topology feature code, which includes a connection method description field, is transformed into a structured target topology table, realizing the automated construction and accurate mapping of network topology relationships. By automatically recognizing and generating a target topology table containing global relationships, the lag and error rate caused by manual configuration are reduced, the transparency and accuracy of the scheduling device's network topology perception are improved, and the efficiency and accuracy of the scheduling device in network scheduling are enhanced.

[0110] Step S204 According to the target topology table, the first optical module and the second optical module are connected.

[0111] When the scheduling device is an OCS switch, the optical signal can be switched from the original cross-connect port to the selected target cross-connect port by controlling the optical cross-connect matrix inside the OCS, thus realizing the physical link connection between the first optical module and the second optical module. When the scheduling device is another type of device, the connection between the first optical module and the second optical module can be realized in a corresponding manner.

[0112] In this embodiment, by performing physical layer network connections according to the automatically generated target topology table, it is ensured that the switching of physical links within the scheduling device is consistent with the actual topology mapping relationship of the optical modules at both ends, thereby reducing port or mapping errors that may be caused by manually configuring scheduling commands and improving the efficiency and accuracy of network scheduling.

[0113] As mentioned earlier, the target topology table can also be updated. The following provides an example update method.

[0114] In optional embodiments, such as Figure 3 As shown, the method further includes:

[0115] S300, obtain the updated first topological feature code and / or the updated second topological feature code.

[0116] S302, Update the target topology table according to the updated first topology feature code and / or the updated second topology feature code.

[0117] In some embodiments, when an optical module undergoes physical insertion / removal, port change, or network layer device migration, the corresponding field in its internal topology feature code will be updated. The scheduling device can poll the topology feature codes of each optical module at preset time intervals and compare the obtained topology feature codes or version numbers each time to perceive the update status of the topology feature codes in real time. In some embodiments, the topology feature codes can also be sent to the scheduling device by the optical module periodically or proactively when an update to the topology feature code is detected. After the target topology table is updated, the scheduling device can also send the updated target topology table to network management or control terminals for synchronization or display. By perceiving and synchronizing changes in the topology feature codes within the optical modules in real time to update the target topology table, the time for network topology information perception and import can be reduced, the operation and maintenance costs of network scheduling can be lowered, and the efficiency and accuracy of network topology information import can be improved.

[0118] In practical applications, the target topology table can be updated in various ways. The following provides an exemplary update method.

[0119] In an optional embodiment, the first optical module and the second optical module are coupled (establish an optical path connection) through a first optical path, the first optical path having a corresponding priority, the first topology feature code including the optical module status identifier of the first optical module, and the second topology feature code including the optical module status identifier of the second optical module. For example... Figure 4 As shown, step S302 may include:

[0120] S400, if the optical module status identifier of the first optical module and / or the optical module status identifier corresponding to the second optical module are abnormal, a second optical path is determined from the target topology table according to the priority corresponding to the first optical path, wherein the second optical path is used to couple the first backup optical module and the second backup optical module.

[0121] S402, an adjustment command is sent to the first backup optical module and the second backup optical module to connect the first backup optical module and the second backup optical module.

[0122] S404, if the first backup optical module and the second backup optical module are successfully connected, update the target topology table.

[0123] Optical module status indicators can include normal, abnormal, pending adjustment, offline, etc. The scheduling device can poll the status indicators of each optical module in real time through pre-established connection channels (such as I2C communication). When an optical module status indicator is found to be abnormal, the scheduling device can also send a reporting signal to relevant devices and mark the first optical path as abnormal in the target topology table. The priority of the second optical path determined by the scheduling device can be higher than or equal to the priority of the first optical path. The topology feature code can also include fields such as a command receiving bit. When an optical module does not receive a command from the scheduling device, the content of the command receiving bit can be "no command". The adjustment command can modify the content of the command receiving bit of the topology feature code in the backup optical modules (including the first backup optical module and the second backup optical module) to "optical path switching adaptation". When other commands are received from the scheduling device, the content of the command receiving bit can also be "power calibration", "port disabled", etc. The adjustment command can also update relevant fields of the topology feature code in the backup optical module, such as the identifier of the port connected to it on the scheduling device, and the peer topology association information. In some embodiments, the backup optical module can send an acknowledgment signal to the scheduling device after receiving an adjustment instruction. The scheduling device only performs internal cross-matrix switching to connect the first backup optical module and the second backup optical module upon receiving the acknowledgment signal. When updating the target topology table, the first optical path can be marked as "unavailable" or "abnormally offline," and a notification signal such as "topology change" can be sent to the network management or control terminal.

[0124] In this embodiment, by monitoring the optical module status identifier in real time and combining it with the optical path priority (an identifier used to characterize the priority order of optical paths during scheduling or switching) to switch the second optical path to update the target topology table, the connection action of the backup optical module and the logical topology record are linked in real time. This ensures the continuity of high-priority services while improving the efficiency of automated processing from anomaly detection to link reconstruction and the consistency of topology status.

[0125] During network scheduling, the backup optical module can also adjust its module status flag in real time. The following provides an exemplary module status flag adjustment process.

[0126] In an optional embodiment, when adjustment instructions are issued to the first backup optical module and the second backup optical module:

[0127] (1) If the first backup optical module returns a confirmation signal in response to the adjustment command, the first backup optical module sets its module status flag to pending adjustment.

[0128] (2) If the second backup optical module returns a confirmation signal in response to the adjustment command, the second backup optical module sets its module status flag to pending adjustment.

[0129] If the first backup optical module and the second backup optical module are successfully connected:

[0130] (1) The first backup optical module sets its module status flag to normal.

[0131] (2) The second backup optical module sets its module status flag to normal.

[0132] In some embodiments, the backup optical module can verify the adjustment command using methods such as CRC cyclic redundancy check or hash check, and return an acknowledgment signal when the verification passes. In other embodiments, the adjustment command is encrypted during transmission. In this case, the backup optical module needs to decrypt the received adjustment command and compare the fields such as the scheduling device identifier in the adjustment command. Only after confirming that the command was sent correctly will it return an acknowledgment signal and adjust its own module status identifier. The scheduling device can start a timer after sending the adjustment command. If it does not receive acknowledgment signals from both ends within a preset threshold (e.g., 20ms), it determines that the second optical path is unavailable, automatically triggers an abnormal rollback, cancels the adjustment command, and re-selects the optical path.

[0133] In this embodiment, by switching the module status identifier between the pending adjustment and normal states, setting the module status identifier to pending adjustment in the initial stage of adjustment can prevent switching to the second optical path before the backup optical module is ready; setting it to normal after successful adjustment completes the final confirmation of the availability of the second optical path, thereby improving the reliability and response speed of network scheduling.

[0134] In addition to the network scheduling that responds to the optical module status as described above, the scheduling device can also proactively perform network scheduling upon receiving corresponding instructions. An exemplary scheduling method is provided below.

[0135] In optional embodiments, such as Figure 5 As shown, the method further includes:

[0136] S500, receive a service scheduling instruction, the service scheduling instruction being used to connect the first target optical module and the second target optical module.

[0137] S502, obtain the first target topology feature code in the first target optical module and the second target topology feature code in the second target optical module.

[0138] S504, Update the target topology table according to the first target topology feature code and the second target topology feature code.

[0139] S506, after the target topology table is updated, connect the first target optical module and the second target optical module.

[0140] Service scheduling instructions can originate from the visual interface of a network management or control terminal, automated scripts, etc. These instructions may include the connection method between the target optical module (including a first target optical module and a second target optical module) and the scheduling device, as well as the priority of the optical path between the first and second target optical modules. In some embodiments, after receiving a service scheduling instruction, the scheduling device can retrieve the occupancy status of the target optical modules in the current target topology table. If the target optical module is already occupied, the priority of the optical path occupied by the current target optical module can be compared with the priority in the service scheduling instruction. If the priority in the service scheduling instruction is higher, the target optical module can be preempted. After the first and second target optical modules are successfully connected, the updated target topology table can be synchronized to the source device or terminal of the service scheduling instruction for visual display.

[0141] In this embodiment, the connection between the first target optical module and the second target optical module is realized in response to the service scheduling command, which improves the flexibility and automation of network scheduling, shortens the response cycle of network scheduling, and ensures the accuracy and consistency of topology information in network scheduling.

[0142] In practical implementation, the connection between the first target optical module and the second target optical module can be achieved in various ways. An exemplary connection method is provided below.

[0143] In an optional embodiment, the service scheduling instruction includes a port identifier associated with the first target optical module and a port identifier associated with the second target optical module on the scheduling device. S506 includes: establishing a third optical path connection between the port corresponding to the port identifier associated with the first target optical module on the scheduling device and the port corresponding to the port identifier associated with the second target optical module on the scheduling device.

[0144] The scheduling device can control its internal optical cross matrix and adjust the tilt angle of the micromirrors to achieve beam deflection and alignment, guiding the optical signal input from the first target optical module to the port output to the second target optical module, thereby establishing a third optical path connection.
