According to the method provided by the embodiment of the application, the first route with the shortest route distance is selected according to the preset rule, and then the second route corresponding to the first route and having different optical cable sections and different pipeline sections is selected according to the preset rule, so that the search of the double routes is completed. In other words, the dual routes searched by the embodiment of the present application correspond to different optical cable segments and pipeline segments, where a pipeline segment is a physical facility for protecting or carrying an optical cable, that is, if an information transmission fault occurs in a pipeline segment in a certain geographic area of the first route, the second route is switched to perform information transmission, so that the geographic area in which the fault occurs can be effectively avoided, and further normal information transmission is realized, and further, the first route and the second route are the shortest routes selected by preset rules, so that the method of the embodiment of the present application can also ensure transmission performance and transmission efficiency of information transmission.
The method provided by the embodiment of the application is further described in detail with reference to the attached drawings.
Referring to fig. 2, an embodiment of the present application provides a method for searching a dual route, which includes the following specific processes:
step 201: selecting a first route with the shortest route distance from a plurality of routes for communicating a first node with a second node according to a preset rule;
in this embodiment of the present application, the first node and the second node are two different computer rooms, where the node information of the first node or the second node may include but is not limited to: the method comprises the following steps of obtaining a machine room name, a machine room ID, a service attribute of the machine room, a region where the machine room is located, the type of equipment in the machine room and the model of the equipment in the machine room. Based on this, a plurality of routes for communicating the first node and the second node may be understood as a plurality of different paths where the device of the first node is connected to the device of the second node.
Understandably, for example, in traffic planning, the length of a route affects the transit time of two places, and routing is the same, and the routing distance will also affect the performance of information transmission. Therefore, after determining a plurality of routes for communicating the first node and the second node, it is further necessary to select a first route having the shortest route distance from the plurality of routes according to a preset rule.
Specifically, the preset rule is a preset method for selecting the shortest route distance, and the setting of the preset rule will affect the transmission performance of the first route selected, so the following three ways of selecting the first route according to the preset rule are proposed in the embodiment of the present application.
It should be understood by those skilled in the art that the following three ways can be used to split and combine the technical features arbitrarily according to the practical application requirement on the premise that the first route can be selected.
The method comprises the steps of obtaining the hop counts of fiber core bundles of a plurality of routes, selecting the route with the hop counts of the fiber core bundles larger than a preset threshold value as an alternative route, taking a single alternative route as a first route in response to the selection of the single alternative route, taking the length of the fiber core bundle of the plurality of alternative routes in response to the selection of the plurality of alternative routes, and taking the alternative route with the shortest fiber core bundle as the first route.
Based on the mode, by combining the hop count and the length of the fiber core bundle, the transmission performance of the shortest route and the construction cost of the shortest route can be comprehensively considered, namely, the raw materials required for constructing the shortest route in an actual scene are effectively reduced, and the transmission speed for selecting the shortest route is effectively improved.
And secondly, determining a plurality of optical cable sections corresponding to each route aiming at each route in the plurality of routes, determining a plurality of pipeline sections corresponding to the plurality of optical cable sections respectively, calculating the sum of the lengths of all the pipeline sections corresponding to each route, taking the calculated sum of the lengths as the length of the pipeline section of each route, and selecting the route with the shortest length of the pipeline section as the first route.
Based on the above manner, the shortest route is selected through calculation of the length of the pipeline section, that is, the pipeline section is a section of pipeline for protecting the optical cable section, and in an actual scene, the actual length of the optical cable corresponding to the route is difficult to calculate, but the length of the pipeline section is better obtained, so that the accuracy and the feasibility of the finally selected route being the shortest route are improved through the manner.
Furthermore, the hop count of the fiber core bundle of each route can be obtained, and the route with the least hop count of the fiber core bundle and the shortest length of the pipeline segment is used as the first route.
Based on the mode, the transmission performance of selecting the shortest route can be further effectively improved by combining the minimum hop number of the fiber core bundle.
And thirdly, screening out a plurality of candidate routes meeting the service requirement from the plurality of routes, and selecting the first route with the shortest route distance from the plurality of candidate routes.
Specifically, the service requirement may be a limitation on a type of the optical cable, and in this case, first, a plurality of optical cable segments corresponding to each of the plurality of routes are obtained, then, a target optical cable type is obtained according to the service requirement, the optical cable types of the optical cables to which the plurality of optical cable segments belong are determined, routes that are not the target optical cable type are screened out, and candidate routes meeting the service requirement are obtained after the screening out. The optical cable type can be a trunk, a distribution line, a relay, a contact, an intra-office optical cable and the like, the search of the optical cable type is limited according to the service requirement, and the speed of searching the shortest route is accelerated.
The service requirement may also be a limitation on an available state of the optical cable segment, in which case, first, a plurality of optical cable segments corresponding to the plurality of routes are obtained, and routes corresponding to the optical cable segments in an unavailable state are screened out according to the service requirement, and after screening out, candidate routes meeting the service requirement are obtained.
Based on the mode, through pre-screening of the service requirements, the shortest route selected finally can be guaranteed to be the route meeting the service requirements, the screening time is effectively saved, and the screening accuracy is improved. In an actual application scene, the screening efficiency and accuracy in the actual application scene can be effectively improved by limiting the type of the optical cable and/or the available state of the optical cable section.
Further, in some possible scenarios, the service requirement may also be a last fiber pair identifier, and the last fiber pair identifier may be specifically used in a service requirement scenario of dual-fiber search; the service requirement can also be the number of available fiber cores, and the number of available fiber cores can be specifically used in a service requirement scene of single-fiber search; the traffic demand may also be in fiber mode, which may include single mode, multi-mode, and gigabit multi-mode.
Step 202: determining N first optical cable sections corresponding to the first route and M first pipeline sections corresponding to the N first optical cable sections;
in an embodiment of the present application, the first duct section is a section of duct for protecting or carrying the first cable section. Wherein N, M is an integer of 1 or more.
Specifically, the N first cable segments jointly form a cable segment group, that is, the route is carried on the optical cable, and the optical cable is formed by cable segments, so that the route is formed by an ordered sequence of a group of cable segments. For example, one route corresponds to 3 cable segments: a cable segment 1; a cable segment 2; cable section 3, the 3 cable sections can be considered as a group or a sequence.
Step 203: selecting a second route with the shortest route distance from the plurality of routes not including the first route according to the preset rule;
in this embodiment, the second route corresponds to Y second cable segments, the second cable segments correspond to Z second duct segments, the second cable segments are cable segments different from the first cable segments, and the second duct segments are cable segments different from the first duct segments. Wherein Y, Z is an integer of 1 or more.
Specifically, the second cable segment is a different cable segment from the first cable segment, and the N first cable segments corresponding to the first route may be regarded as a first cable segment group corresponding to the first route, that is, the first cable segment group is a set composed of one or more first cable segments; the Y second cable segments corresponding to the second route may be regarded as the first cable segment group corresponding to the second route, that is, the second cable segment group is an aggregate of single or multiple second cable segments. Here, the first cable segment group does not have an intersecting relationship with the cable segments included in the second cable segment group.
For example, the group of cable segments for a-routing includes: the optical cable comprises an optical cable section 1, an optical cable section 2 and an optical cable section 3; the optical cable segment group of the B route comprises: cable section 2, cable section 4, cable section 5. The optical cable section 2 with the intersection relationship exists in the optical cable section group of the route a and the route B, so that the route a and the route B do not accord with the condition of dual-route selection, in other words, the condition is met when the intersection of the optical cable section group of the route a and the optical cable section group of the route B is empty.
It will be appreciated that the second duct section is a different cable section than the first duct section, as is the same with the above understanding of the relationship between the second cable and the second cable section, and will not be described in detail herein.
Based on the method, double routes corresponding to different optical cable sections and different pipeline sections are searched.
Further, in practical application, the searched dual route may be displayed on the display screen, that is, the first display information of the first route and the second display information of the second route are obtained in response to displaying the route information of the first route and the second route, and then the first display information and the second display information are sent to the display screen, so that the display screen displays the first display information and the second display information according to the display screen.
Specifically, the acquired first display information and the acquired second display information have priority identifiers, the priority identifiers represent display priorities of the display information, and the display information is displayed on a display screen according to a corresponding relationship between the priority identifiers and display areas. Generally, the display priority of the first display information is higher than that of the second display information, and therefore, the first display information is displayed in the first display region and the second display information is displayed in the second display region, and the first display region is located above the second display region or the first display region is more conspicuous than the second display region.
Based on the method, through the configuration of the display priority, the better first routing information is displayed in the upper first display area or the more prominent first display area, so that the user can pay attention to the first routing information at the first time, namely, the visual experience of the user is effectively improved.
Optionally, the first display information may be obtained by determining an area identifier of the first route, N first cable segments corresponding to the first route, an available state of the N first cable segments corresponding to the first route, M first pipe segments corresponding to the first route, and a total length of the M first pipe segments corresponding to the first route, and using the determined information as the first display information of the first route.
