Background
The traditional wavelength division is still applied to the existing network in a large amount at present, and since the traditional wavelength division transmission channel depends on the station-by-station tail fiber connection to realize the end-to-end connection, the connectivity of the transmission channel must depend on the integrity of all machine line facilities along the path. Due to the interruption of the existing network optical cable or the single board failure in remote areas caused by natural disasters, the transmission network is interrupted. And under the condition that the optical cable interruption cannot be repaired in a short period or the single board fault is not replaced by spare parts in a short period, the service interruption time is longer. Therefore, in order to ensure the security of the transmission network, it is generally necessary to schedule an emergency transmission channel for important services to ensure the security of the bearer service and the robustness of the network. The traditional wave division transmission channel emergency rescue mechanism mainly depends on the cooperation of electronic information of maintenance personnel and an equipment network management system, redundant channels are cleared section by section on the existing network by the maintenance personnel, and then an emergency scheduling scheme is compiled according to redundant channel information.
The existing wavelength division emergency channel scheduling has the following defects: 1) the manual command and scheduling is faced with too much time consumption, especially in the case of complex networking. By the automatic generation method and the device of the wave division emergency transmission channel scheduling scheme, the standby channel scheduling routing scheme can be quickly determined. 2) When a network is damaged in multiple places, the existing manual analysis cannot simultaneously respond to multiple emergency targets. By the automatic generation method and the automatic generation device for the wavelength division emergency transmission channel scheduling scheme, the optimal emergency roundabout routing scheme based on the resource utilization rate and the scheduling time is quickly provided. 3) Manual scheduling does not provide an optimal solution quickly for scenarios across multiple states. By the automatic generation method and the device of the wave division emergency transmission channel scheduling scheme, the emergency scheduling routing scheme of more than two states can be automatically analyzed and provided. The inventor believes that if a wavelength division transmission network topological graph containing a large network element, a small network element, a main channel route and a standby channel route, which is formed based on wavelength division transmission basic configuration data, is established, when the main channel route is interrupted, the large network element at the source end, the large network element at the destination end and an interruption paragraph of the interrupted service are determined, and a wavelength division emergency transmission channel scheduling generation model is combined, an optimal wavelength division emergency transmission channel scheduling scheme can be obtained, so that the rapid scheduling of the emergency transmission channel is effectively supported. In view of the above, the present inventors have completed the present invention.

The number of the multiplexing sections/regeneration sections is calculated by the sum of the number of the connection sections between the large network elements and the number of the OA equipment.
The wave division emergency transmission channel scheduling generation model software algorithm comprises the following steps: step 1, starting from a source end large network element, searching all small network elements hung down, and accordingly obtaining small network elements associated with the source end large network element; step 2, correlating channel basic data through the small network elements, judging whether LOS alarms exist at ports of small network elements transmitted at two ends of a channel, skipping the corresponding channel if the LOS alarms exist, continuously correlating the next channel, and recording the small network element at the opposite end if the LOS alarms do not exist, thereby obtaining the small network element at the opposite end without faults associated with the channel; step 3, judging whether the large network element to which the small network element belongs is a selected host large network element or not by correlating all searched opposite small network elements, if not, continuously searching other opposite small network elements related to the large network element channel, recording that the next circulation process of the traversed small network element does not analyze the network element, continuously executing the step 2, if so, obtaining an emergency scheme, and traversing all related small network elements related to the channels according to the emergency scheme; step 4, circularly executing the step 2 to the step 3 until the large network element to which the small network element at the opposite end belongs is the selected large network element at the host end, thereby obtaining an emergency scheme, wherein the analyzed small network elements are not repeatedly associated any more, and a plurality of emergency schemes are obtained until all path analysis is completed; and 5, index quantification scoring is carried out on the multiple emergency schemes, so that the optimal wavelength division emergency transmission channel scheduling scheme is determined according to the total score of each emergency scheme.
As shown in fig. 3, the software algorithm of the wavelength division emergency transmission channel scheduling generation model includes the following steps: step 1, starting to inquire all small network elements from a source end large network element; step 2, inquiring a standby wave channel through a small network element; step 3, judging whether the LOS alarm exists at the network element port of the AZ end of the standby channel, if so, skipping the channel, continuing to analyze other channels, returning to the step 2, and otherwise, entering the step 4; step 4, finding out a small network element at the opposite end of the standby channel; step 5, judging whether the large network element to which the small network element at the opposite end belongs is a large network element at a host end, if not, returning to the step 1, and if so, entering the step 6; and 6, obtaining an emergency transmission channel scheduling scheme.
A method and a device for automatically generating a wavelength division emergency transmission channel scheduling scheme utilize basic configuration data of a traditional wavelength division transmission network and combine an emergency transmission channel scheduling generation model to realize full-automatic analysis of wavelength division emergency transmission channel paths and present a preferred scheme with shortest wavelength division emergency transmission channel paths, minimum manual hopping, safest and corresponding full-process routing information. The device network management system collects resource data of large network elements, small network elements, channels, channel routes and the like of the wavelength division transmission network, and static data of wavelength division circuits, fiber jumps, transmission multiplexing sections/regeneration sections, fault multi-generation sections, protection sections and the like managed by maintenance personnel. And executing the emergency transmission channel path index quantitative calculation rule and the analysis algorithm.
The emergency transmission channel path index quantitative calculation rule comprises the following contents: the lower the quantitative total score is, the better the emergency path is. The indexes include 5 items, namely the number of channels, the number of jumping fibers, the number of multiplexing sections/regeneration sections, the number of fault multi-generation sections and the number of protection sections.
1) The number of channels, which refers to the connections between different large network elements. The fewer channels the scheduling channel passes through, the faster the scheme is implemented and the more secure it is. And judging the emergency scheduling scheme with the least number of channels as the shortest path. Because the channel is judged by the current fault, the channel which has no fault and is the established standby channel is selected, the influence of the channel on the whole emergency transmission channel scheduling scheme is low, and the score level is set to be low.
2) The number of the jumping fibers refers to the connection between small network elements in the same large network element. The fewer hops required to schedule a channel, the faster the scheme can be implemented and the more secure it is. And the emergency scheduling scheme for judging the minimum number of the jumping fibers is the minimum manual jumping. As the fiber skipping needs to be implemented on site by constructors, the operation consumes more time, the influence of the fiber skipping on the whole emergency transmission channel scheduling scheme is higher, and the score level is set to be high.
3) Number of pass-through multiplexing section/regeneration section: the multiplexing section is a section of OTM-OTM (optical terminal multiplexer), the regeneration section is a section of OTM-OA (optical amplifier), OA-OA, OA-OTM; judging whether OA optical amplifier equipment exists between different large network elements, and if not, recording the OA optical amplifier equipment as 1 segment; the number of paragraphs +1 for each additional OA device. The fewer paragraphs the dispatch channel passes through, the faster and more secure the implementation of the scheme. Since the paragraphs are already established in the existing transmission network, the paragraphs are generally not created during emergency dispatching (resource application and construction scheme design and implementation are time-consuming). Therefore, the influence of the paragraphs on the overall emergency transmission channel scheduling scheme is low, and the score level is set to be low.
4) Number of multiple fault sections (recent fault statistics): the emergency scheduling scheme should avoid the fault multiple sections as much as possible. And judging the emergency scheduling scheme with the least fault multi-generation sections as the safest. And setting the score level as high when the number of the channel segments with the alarm interruption times of more than or equal to 5 in the last 30 days is larger. And (4) setting the score level as medium when the number of the channel segments with the alarm interruption times of more than or equal to 3 and less than 5 in the last 30 days. And setting the score level to be low when the number of the channel segments with the alarm interruption times of more than or equal to 0 and less than 3 in the last 30 days. Wherein, the score level is high, medium and low 3 grades, and the weight value is respectively: the height is 3 points, the middle is 2 points and the low is 1 point.
5) Number of protected paragraphs: since the protection paragraph is the optimal choice, it acts as a subtractive term. The score level is set to-3 or-2 or-1.
Total score of the protocol 1 score to sum of score 5 scores. The score item 1 is a channel number weighted value; the scoring item 2 scores the number of the jumping fibers; the score item 3 is the weighted value of the number of multiplexing sections/regeneration sections; the score 4 is the number of multiple fault sections and the weight value; the score 5 is a protection paragraph number weight value.
