The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of methods and systems consistent with some aspects of the present invention as detailed in the appended claims.

[0060] In order to better understand the present invention, the terms appearing in the embodiments of the present invention are first explained below.

[0061] The transmission network is a network used as a transmission channel. It is generally built under the switching network, data network and support network. It is used to provide signal transmission and conversion. It belongs to the basic network of the above three networks. The transmission network generally studies optical cables, copper wires, signal amplifiers, interfaces, connectors, interface converters, microwave systems, PDH, SDH, WDM, ASON and satellites. The main contents of the model include transmission circuits, SDN systems, TMUX systems, OCP systems, OLP systems, wavelength division systems, leased optical fibers, leased wavelengths, optical cable bearing relationships and computer room resources. The model material mainly uses ER relationship diagrams to describe the relationship between model entities.

[0062] The transmission circuit scene contains physical objects and basic information of the transmission circuit, mainly including business information such as transmission relay, transmission channel, and transmission business circuit.

[0063] The SDH transmission system has a unified frame structure digital transmission standard rate and a standard optical path interface, which enables network management systems to communicate with each other, so it has good horizontal compatibility. It is fully compatible with the existing PDH and can accommodate various new business signals, forming a global unified digital transmission system standard and improving network reliability.

[0064] The TMUX system scenario mainly includes TMUX system branches, TMUX multiplexing segments, TMUX system segments, and TMUX time slots.

[0065] The OCP system scenario mainly includes OCP system branch line, OCP multiplexing section, OCP system section, OCP time slot and fiber core.

[0066] OLP (Optical Fiber Line Auto Switch Protection Equipment)——Optical Fiber Line Auto Switch Protection Equipment. The optical fiber automatic switching protection system (abbreviated as OLP) is an automatic monitoring and protection system that is independent of the communication transmission system and is completely based on the physical link of the optical cable. The scenarios mainly include OLP system branches, OLP multiplexing sections, OLP system sections, OLP time slots, and fiber cores.

[0067] Wavelength Division Multiplexing (WDM) is a technology that combines two or more optical carrier signals of different wavelengths (carrying various information) at the transmitting end through a multiplexer (also called a combiner, Multiplexer) and couples them to the same optical fiber of the optical line for transmission; at the receiving end, the optical carriers of various wavelengths are separated by a demultiplexer (also called a splitter or demultiplexer), and then further processed by the optical receiver to restore the original signal. This technology of simultaneously transmitting two or more optical signals of different wavelengths in the same optical fiber is called wavelength division multiplexing.

[0068] Optical fiber, also known as optical fiber, is a fiber made of glass or plastic that uses the principle of total internal reflection to transmit light in these fibers. The tiny optical fiber is encapsulated in a plastic sheath so that it can be bent without breaking. Usually, the transmitting device at one end of the optical fiber uses a light-emitting diode or a laser to send light pulses into the optical fiber, and the receiving device at the other end of the optical fiber uses a photosensitive component to detect the pulses.

[0069] Wavelength refers to the distance a wave travels in one vibration cycle. That is, along the propagation direction of the wave, the distance between two adjacent points whose vibration phases differ by 2π. The wavelength λ is equal to the product of the wave speed u and the period T, that is, λ=uT. Waves of the same frequency propagate at different speeds in different media, so the wavelengths are also different.

[0070] Optical cable is a communication cable assembly that uses one or more optical fibers placed in a sheath as a transmission medium and can be used alone or in groups. Optical cable is mainly composed of optical fiber (glass fiber as thin as hair) and plastic protective sleeve and plastic outer skin. There is no gold, silver, copper, aluminum or other metals in the optical cable, and it is generally not worth recycling. Optical cable is a communication line that a certain number of optical fibers form a cable core in a certain way, which is covered with a sheath, and some are also covered with an outer sheath to realize the transmission of optical signals. That is: a cable formed by optical fiber (optical transmission carrier) through a certain process. The basic structure of the optical cable is generally composed of several parts such as cable core, reinforcing steel wire, filler and sheath. In addition, there are waterproof layer, buffer layer, insulated metal wire and other components as needed.

[0071] The bearer relationship is used to record the relationship between the fiber core, wavelength, tmux time slot and time slot.

[0072] The embodiments of the present invention are described below with reference to the accompanying drawings.

[0073] like Figure 1 As shown, the first aspect of the present invention provides a circuit length calculation method based on a digital twin model, comprising:

[0074] S1: Establish a digital twin model based on the physical optical cable information of the communication network.

[0075] The physical optical cable information in step S1 includes: physical optical cable medium, bearer transmission system, channel, relay, and physical attribute data.

[0076] Furthermore, the above-mentioned physical optical cable medium records basic information such as the material, type (such as single-mode or multi-mode optical fiber), number of cores, etc. of the optical cable, which helps to understand the transmission performance and physical characteristics of the optical cable; the bearer transmission system understands the type of transmission system carried by the optical cable, such as SDH (Synchronous Digital Hierarchy), DWDM (Dense Wavelength Division Multiplexing), etc.; the channel records the channel configuration in the optical cable, including the number, capacity, wavelength, etc. of channels; the relay collects information on the relay equipment, such as the location of the relay station, the equipment type, performance parameters, etc.; the physical property data records the physical properties of the optical cable, such as length, diameter, weight, and sheath material.

[0077] When building a twin model, data is first collected on the optical cable to collect the operating status data of the optical cable in real time, and then the collected data is cleaned to remove noise, outliers and duplicate data. After obtaining the data, the appropriate modeling method is selected according to the characteristics and requirements of the optical cable, such as physical modeling to build a model based on the physical properties and transmission principles of the optical cable, or machine learning modeling to identify the failure mode and performance trend of the optical cable by training the model.

[0078] After obtaining the basic model, constructing a three-dimensional model, that is, using three-dimensional modeling software or tools to build a three-dimensional model of the optical cable according to the actual layout and configuration of the optical cable, helps to intuitively display the physical structure and spatial relationship of the optical cable.

[0079] S2: Receive optical cable length information through the digital twin model.

[0080] The optical cable length information in step S2 includes: optical cable length and optical cable sheath length.

[0081] Based on the digital twin model constructed in step S1, since it inherits the real-time collected optical cable operation status data, it can realize dynamic updating and real-time monitoring of the model, as well as the physical information of related communication circuits, so the optical cable length information can be obtained through the digital twin model in step S2.

[0082] S3: Obtain the upper-layer bearer resource relationship according to the data bearer relationship.

[0083] The upper-layer bearer resource relationship in step S3 specifically includes:

[0084] The optical cable section is the first layer, the upper layer carries the transmission circuit link is the middle layer, and the upper layer carries the transmission circuit link through the divided time slots to continue to carry the transmission circuit link is the second layer;

[0085] The optical cable section is the first layer, the upper layer carrying the wavelength division system is the middle layer, and the upper layer carrying the wavelength division system through the divided channels to carry the transmission circuit link is the second layer;

[0086] The optical cable section is the first layer, the upper layer carrying the SDH system is the middle layer, and the upper layer carrying the transmission circuit link in the time slot divided by the SDH system is the second layer;

[0087] The optical cable section is the first layer, the upper layer carrying the TMUX system is the middle layer, and the upper layer carrying the transmission circuit link divided by the TMUX system in the time slot is the second layer.

[0088] The optical cable segment includes an optical cable, leased optical fiber, and leased wavelength.

[0089] Since the optical cable, leased optical fiber and leased wavelength constitute the physical line of the transmission network, and the optical fiber in the optical cable carries the service function, the bearer relationship can be obtained according to the bearer calculation details in step S3.

[0090] The specific bearing relationship is as follows: Scenario 1: When the bearing is calculated starting from the optical cable, the optical cable segment is the first layer, the upper layer directly bears the transmission circuit link as the second layer, and the transmission circuit can continue to bear the transmission circuit link by dividing the time slot as the third layer...; Scenario 2: When the bearing is calculated starting from the optical cable, the optical cable segment is the first layer, the upper layer bears the wavelength division system as the second layer, and the wavelength division system divides the channel to bear the transmission circuit link as the third layer...; Scenario 3: When the bearing is calculated starting from the optical cable, the optical cable segment is the first layer, the upper layer bears the SDH system as the second layer, and the time slot divided by the SDH system bears the transmission circuit link as the third layer...; Scenario 4: When the bearing is calculated starting from the optical cable, the optical cable segment is the first layer, the upper layer bears the TMUX system as the second layer, and the time slot divided by the TMUX system bears the transmission circuit link as the third layer...; The optical cable of the first layer can be replaced by leased optical fiber and leased wavelength, and each layer can be used as the first layer for resource bearing.

[0091] S4: recursively calculate and obtain circuit length information according to the upper-layer bearer resource relationship and the optical cable length information.

[0092] The calculation method of the circuit length information in step S4 specifically includes:

[0093] The length of the optical cable is summed based on the length of the optical cable segments;

[0094] The optical fiber path length is calculated by summing the lengths of the optical fiber path segments;

[0095] The length of the OLP system segment is summed based on the length of the occupied optical cable segments;

[0102] The length of the TMUX multiplexing segment is summed with the length of the TMUX system segment;

[0103] SDH system segment length: when the SDH system occupies optical cables, the length of the occupied optical cable segments is calculated; when the SDH system occupies optical fiber paths, the length of the optical fiber paths is calculated; when the SDH system occupies OLP, the length of the occupied OLP segments is calculated; when the SDH system occupies wavelength paths, the length of the occupied wavelength paths is calculated; when the SDH system occupies OCP, the length of the OCP multiplexing segments is calculated; when the SDH system occupies wavelength division, the length of the DWDM multiplexing segments is calculated; when the SDH system occupies TMUX, the length of the TMUX multiplexing segments is calculated; when the SDH system occupies SDH, the length of the SDH multiplexing segments is calculated;

[0104] The length of the SDH multiplex section is summed according to the length of the SDH system section;

[0106] The length of the PDH multiplex section is summed based on the length of the PDH system section;

[0107] The circuit length is calculated by summing the lengths of the circuit segments.

[0110] When the circuit length is the length of an overseas leased channel, it is summed by the local routing length;

[0111] When the circuit length is the length of the recursive circuit segment, the circuit lengths occupied by the circuit segment are summed;

[0112] When the circuit length is the service circuit length, the sum is calculated based on the length of the service circuit segments opened on the channel.

[0113] In step S4, since the bearer transfer relationship of the long-distance transmission network is realized by the underlying medium carrying the transmission system and the transmission system carrying the circuit, the upper-layer bearer resource length can be calculated based on the data bearer transfer relationship obtained in step S3. The main thing to note is that the long-distance transmission network components are not fixed hierarchical relationships, so a recursive method is required to penetrate the data to obtain length information.

[0114] S5: Update the circuit length information to the digital twin model to complete the circuit length calculation.

[0115] Finally, in step S5, the calculated length information is input into the digital twin model to improve the query efficiency. Afterwards, various query methods such as real-time query and data sharing can be supported based on the length information of the digital twin model.
