However, this method cannot be combined with the physical routing of the optical network, resulting in two problems: physical routing detours (due to excessive distances) and the existence of the same routing segment between the primary and backup networks, which affect the customer experience.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0045] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0046] The existing OTN premium leased line service activation scheme has two problems: physical route detour (excessive distance) and co-routes between primary and backup. The existing technology does not combine the physical route of the optical cable to calculate the optimal primary route, nor does it avoid co-routes at the atomic layer to select the backup route.
[0047] This invention, based on physical routing data, filters optical channels and network element sets according to the rate requirements of OTN premium private network service circuits, and solves the problem of excessively long physical route detours by prioritizing the shortest physical route and the fewest hops. Furthermore, it calculates the avoidance set of co-routes at the atomic level of identifier points, resolving the issue of primary and backup co-routes, effectively improving the security and latency of government and enterprise services. Therefore, this invention provides an automatic routing system and method for OTN premium private networks based on physical routing.
[0048] Example 1
[0049] like Figure 1 As shown, the present invention provides an automatic routing method for OTN premium private networks based on physical routing, comprising the following steps:
[0050] First, obtain the OTN premium private network order information. Based on the obtained orders, obtain the order rate, customer AZ address, serial number, and instance number. The order rate is used for analysis during subsequent optical channel capacity allocation. Based on the order rate, match the rate rule set to obtain the set of available OCH optical channels, which serves as the data basis for route calculation. Obtain the customer's AZ latitude and longitude information for subsequent equipment calculation. Based on the principle of shortest straight-line distance, select the nearest OTN device near the AZ address as the start and end points of the customer's service circuit. The customer's order serial number and instance number are used to analyze the relationship between the circuit and the route.
[0051] Based on the addresses at both ends of the order and the association between the managed equipment and the station, the equipment information at both ends of the circuit is obtained. This equipment information includes the province, city, latitude and longitude, and equipment code of the equipment. The distance is calculated and filtered within a 20-kilometer radius to find the nearest equipment within that range. The specific calculation steps are as follows:
[0052] Obtain the cities at both ends of the order, as well as the GIS address. The radius is 20 kilometers by default. Find the circular optical cable that passes through the given latitude and longitude coordinates as the center and the radius (in meters), and calculate the horizontal and vertical axis lengths of the range.
[0053] The parameters used to calculate the length of the horizontal axis include:
[0054] The longitude of the first point is AJ.
[0055] The latitude (AW) of the first point
[0056] The longitude of the second point is BJ = AJ + 1.
[0057] The latitude of the second point is BW.
[0058] The parameters used to calculate the length of the vertical axis include:
[0059] The longitude of the first point is AJ.
[0060] The latitude (AW) of the first point
[0061] The longitude of the second point is BJ.
[0062] The latitude of the second point is BW = AW + 1.
[0063] Calculate the arc length s using the inverse cosine method:
[0064] s = 2 * Math.asin(Math.sqrt(
[0065] Math.pow(Math.sin(a / 2),2)+Math.cos(radLat1)*Math.cos(radLat2)*Math.pow(Math.sin(b / 2),2)));
[0066] The distance between two GIS addresses can be obtained by multiplying the arc length s by the Earth's radius R: length = s * R;
[0067] Where R = 6,378,137, in meters;
[0068] a = radLat1 - radLat2;
[0069] b = radLng1 - radLng2.
[0070] radLat1 = AW * π / 180,
[0071] radLng1=AJ*π / 180,
[0072] radLat2 = BW * π / 180
[0073] radLng2=BJ*π / 180.
[0074] Filter the list of all devices to select the device closest to the order address within the specified latitude and longitude range.
[0075] The acquired device information is matched with the devices at both ends of the optical channel to obtain the matching result, forming a device site pair. The specific information includes the codes of the two devices, the optical channel between the devices, and the optical channel length, etc. The device site pair is used for subsequent routing calculations.
[0076] By combining OTN optical channel routing data with the managed device network elements and GIS physical location information, the length of the optical channel is calculated.
[0077] Based on the circuit speed and the calculated optical channel length, optical channels that can participate in the circuit calculation are selected. The selection criteria are the length of the optical channel, the capacity of the optical channel, and the name of the optical channel. The optical channel information includes the devices at both ends of the optical channel and the distance between the optical channels.
[0078] The acquired optical channel data is processed to generate an adjacency matrix and routing segments for the points. For example... Figure 3 As shown, the adjacency matrix of a point is a set of devices on the same optical channel that start or end with this device, in the form of key-value pairs. For example... Figure 4 As shown, the routing segment uses key-value pairs to find all optical channels between two devices, filters out the shortest optical channel, and provides its specific length information.
[0079] The value of 'name' is: Device ID - Termination ID;
[0080] allOch: Information on all och channels traversed between the start and end devices;
[0081] bestOch: Filters out the shortest och channel from allOch;
[0082] Based on the order serial number, instance number, and nationwide optical cable data, a route pair with the same route is formed. Specifically, this involves: identifying all optical cable segments occupied by the optical channel; using this data as a basis, filtering out all marker points on these optical cable segments and confirming the location of each marker;
[0083] The formula for calculating the landing point position is: GIS position of the point / 0.0016;
[0084] Based on the point information and landing location of the markers, the position from the point to the line is constructed. The distance between each pair of markers is calculated sequentially. According to the same route determination rule, the distance between markers within ≤5 kilometers is a same route segment, forming a circuit same route pair.
[0085] Based on the processed data, the optical channel path of the OTN private network is calculated, and the flexibility and configurability of the path are realized. This flexibility and configurability are reflected in the ability to select different rates and add different weights according to actual business needs, and to implement two routing schemes, one primary and one backup. This completely achieves device selectability, speed selection, low latency, and high-speed activation.
[0086] The specific calculation logic is as follows: take the starting point station pair as the first open list value, which is also the first result list value;
[0087] Find all the site devices at the other end of the optical channel route that form a connection with the starting point from the adjacency matrix of the starting point device. Based on the GIS information of the device network element, filter out the adjacent site devices that are closest to the starting point and add them to the open list.
[0088] The process iterates through the enabled list, finding the station with the shortest optical channel length, removing it from the enabled list, and adding it to the results list. It also iterates through the adjacency matrix of the stations, identifying all surrounding station devices, calculating the cost based on weights, and selecting the adjacent station with the shortest transfer distance from the starting point, adding it to the enabled list.
[0089] The weight calculation rule is: L = optical channel length / 100000.0 * 5 + number of adapters / 10000;
[0090] The rule for calculating the number of transitions is: for each additional och optical channel traversed, the number of transitions increases by 1.
[0091] The process is repeated iteratively until the result list contains the end station pair, indicating that the optical channel main routing path has been generated.
[0092] Considering that in actual production, the interruption of one route can affect the entire service's operation, a backup solution is needed to ensure that services can be successfully activated when the primary route is interrupted. Therefore, this invention incorporates a backup route calculation rule, and at the same time, avoids the problem of primary and backup routes being the same by using the same route calculation rule.
[0093] Based on the calculated primary optical channel routing path, and combined with the physical routing data of the national first and second trunk lines and important government and enterprise OTN optical cables under management, the optical cables corresponding to these optical channels are selected. All optical channels corresponding to these cables are removed from the full range of optical channels participating in the routing calculation, and co-route data is filtered out. Backup optical channel paths are then determined using routing calculation methods.
[0094] Meanwhile, for some inter-provincial lines, the nodes at both ends of the province are identified based on the calculated primary optical channel path. For routes with a distance greater than 1500 kilometers, 64 city nodes are identified based on the primary path, and backup routes are calculated according to the new equipment sites.

The device information is used to form device site pairs and calculate the routing length of the optical channel.

[0099] The data analysis module is used to identify all optical cable segments occupied by the optical channel based on the order serial number, instance number, and national optical cable data. Based on this data, it filters out all the marker points on these optical cable segments and confirms the landing position of the points. Based on the point information and landing position of the marker points, it constructs the position from point to line, calculates the distance between each pair of marker points in turn, and forms circuit same-route routing pairs according to the same-route determination rules.

[0105] The third acquisition unit is used to calculate the optical channel length based on the OTN optical channel routing data, as well as the managed device network elements and GIS physical location information.
[0106] This invention calculates the device information at both ends of the circuit based on the addresses at both ends of the government and enterprise OTN order and the association between managed devices and sites; it calculates the length of the optical channel by combining OTN optical channel routing data and managed device network element and GIS physical location information; it realizes the association management of device network elements and GIS physical locations, performs logical and physical layer association management of OTN optical channel routing, and ensures the integrity of network element and optical channel physical routing data; it filters optical channels and network elements for calculation based on different service circuit rates, solving the problems of primary and backup co-routing and physical route detours (excessive distance);
[0107] Based on the physical routing data of national backbone and enterprise OTN key optical cables, circuit-related routing pairs are formed. Different weights are added according to different speeds to avoid co-routing segments, and a primary and backup optical channel routing scheme is calculated. Based on the physical routing data, optical channels and network element sets are selected according to the speed requirements of OTN premium private network service circuits, and the problem of physical route detours (excessive distance) is solved by prioritizing the shortest physical route and the fewest hops. Furthermore, the co-routing avoidance set is calculated at the atomic level of the identifier point to solve the problem of primary and backup co-routing, effectively improving the security and latency of enterprise services.
