Description

Technical Field

[0001] The present invention belongs to the technical field of communication network transmission bearer network, and specifically relates to an automatic analysis and calculation method, system and electronic equipment for OTN channel utilization. Background Art

[0002] With the rapid development of science and technology, the transmission network equipment is upgraded very quickly. In the current transmission bearer network, from the access layer, aggregation layer, and backbone layer, the use of OTN (Optical Transport Network) equipment has occupied an important proportion. In order to better plan and manage the OTN transmission network, network maintenance engineers generally need to understand the channel usage in the OTN transmission system in a timely manner. When the channel utilization rate of some multiplexed sections in the system reaches the threshold, the management personnel will apply for adjustment of the wind network to ensure that the services on the entire OTN network can run safely and orderly.

[0003] There are two common statistical methods for channel utilization in the current OTN system: the first is that network management and maintenance personnel will maintain a transmission system channel ledger based on what they have on hand. When a channel is used by OCH (Optical Channel With Full Functionality), the channel is marked as used. When calculating the channel utilization, the system ledger table is manually screened and filtered according to the multiplexing segment to calculate the channel utilization rate in each multiplexing segment.

[0004] The second statistical method is to count two aspects: the first aspect is the line side utilization (channel utilization, time slot utilization), that is, the OTN line side resource utilization, and the second aspect is the branch side utilization (that is, the customer side port utilization). Generally, network management personnel manually calculate the line side utilization (including channel utilization) and branch side utilization through the manufacturer's engineers checking the service configuration on the network management system and combining their own business accounts in the province.

[0005] The above two common OTN channel utilization statistics methods are both completed manually by combining system records, lacking digital operation support. There are mainly the following problems or defects: 1. Counting the channel utilization of a primary system requires manual screening and verification of data on the network management system. However, there are many OTN network management transmission systems in the province, so it takes a long time to complete the statistics. 2. Due to the large number of transmission systems in the province, each time a new channel is added, the ledger maintenance personnel may not update the Excel ledger table data in time, resulting in the channel usage in the ledger being inconsistent with the actual channels in use. The manual maintenance table is maintained for a long time, and the channel utilization rate is calculated based on the ledger data. The final calculated channel utilization rate of the multiplexing section in the system can only be an approximate value that is close to the actual data and is not completely accurate; 3. The query statistical results are not quick and intuitive enough: the traditional manual statistical method is adopted, and digital operation support means are not utilized, which cannot effectively and timely provide supporting data for network planning. Summary of the invention

[0006] The purpose of the present invention is to provide an automatic analysis and calculation method, system and electronic device for OTN channel utilization, so as to solve the technical problem of low accuracy of multiplex section channel utilization calculated by manual statistical method in the prior art.

[0047] Step 6: Count the channels that have been opened in the transmission system The statistical method for the number of opened channels is as follows: 6.1 Extract OCH (Optical Channel) data from the stored subnet connection data; 6.2 According to the subnet connection routing, cross-connection and topology data, the OCH data is routed and concatenated to obtain the complete routing data of each OCH data; 6.3 According to the complete OCH routing data obtained in operation 6.2, take OCH from OCH, traverse the OCH route, extract the network element and channel number passed through in the middle; traverse all OCHs to obtain a set of channels opened in a network element Map1 <mename,List<λ> > 6.4 Take the multiplex segment data generated in step 4, extract the network elements at the A and Z ends of the multiplex segment, associate them with the network element enabled channel set Map1 generated by the previous step c, and calculate the enabled channel list set Map2<segment name, List<λ>> for each multiplex segment; Association extraction rule: The network elements at both ends of the multiplexing section traverse the opened channel numbers respectively. If the same channel number has been opened on the network elements at both ends of the multiplexing section, it is marked that the multiplexing section has opened the channel number, and the channel number and the multiplexing section name are stored in the set Map2; 6.5 According to the mapping relationship between the multiplex section and the transmission system generated in step 5, associate the multiplex section enabled channel number set Map2 generated in operation d, and obtain the enabled channel number list set Map3 of all multiplex sections in the transmission system from to <system name, list <map2>>.

If the ODU routing is not associated with the two ends of the OCH port, filter this ODU and continue to process the next ODU; The 4th type: SDH service associated statistics of the passed multiplex section channels 7.14 Retrieve the virtual port mapping relationship data collected and stored in the database; 7.15 Traverse the virtual port mapping relationship, and extract the wdm physical port + CTP corresponding to the V-SDH virtual port; 7.16 Traverse the list of wdm physical ports + CTPs extracted in 7.15 operation, and perform associated search for subnet connection ODU data; 7.17 Perform routing concatenation on the ODU by associating subnet connection routing, topology, and cross-connection data to obtain the complete routing; 7.18 Based on the ODU end-to-end routing data obtained in 7.17 operation, associate OCH channels and multiplex section data, traverse and analyze which multiplex section channels the service routing passes through, and obtain the set of multiplex section channels occupied by the service Map<V-SDH, List<Map<Section Name, List<λ>>>>.
