Description

Technical Field

[0001] The present application relates to the field of data storage technology, and in particular to a telecommunications service cutover method and device. Background Art

[0002] In existing telecommunications network management, cutover scenarios vary. Different users have different cutover requirements for telecommunications services, such as intra-network element fiber connection adjustment, inter-network element fiber connection adjustment, service extension, service shortening, service addition and subtraction, single disk replacement, and network element replacement.

[0003] For each cutover scenario, a different cutover operation method needs to be used, that is, each scenario requires a corresponding cutover tool, which results in a serious disproportionate relationship between output and revenue in terms of development time and efficiency. Summary of the Invention

[0007] Reconnect the fiber to the port that needs to transmit service data, and search for services based on the atomic network service cutover method until no services are found, thereby determining the corresponding damaged edge site;

[0008] Create new services based on the discovered damaged edge sites;

[0011] When the cutover point is not the source NE and sink NE of the atomic network service, the source NE and sink NE based on the atomic network service start service search respectively;

[0012] When the cutover point is the source network element or sink network element of the original network service, the corresponding sink network element or source network element based on the original network service starts to search for the service.

[0013] With reference to the first aspect, in one embodiment, creating a new service based on a damaged edge site found through a source network element and a sink network element includes:

[0015] When the damaged edge sites found by the source and sink NEs are different NEs, route calculation is performed on the ports of the two NEs at the damaged edge site to form a new local route.

[0016] If the damaged edge site found by the source and sink NEs is the same NE and an old service exists, delete the old service and create a new single-site cross-connect service using the port of the damaged edge site.

[0017] When the damaged edge site found by the source NE and the sink NE is the same NE and no old service exists, a new single-site cross-connect service is created directly using the port of the damaged edge site.

[0018] With reference to the first aspect, in one embodiment, creating a new service based on a damaged edge site found through a source network element and a sink network element includes:

[0019] If the cutover point is the source or sink NE of the original network service, then:

[0020] When the damaged edge site found by the sink NE or source NE corresponds to a new source NE or sink NE, a new single-site cross-connect service is created directly using the port of the damaged edge site.

[0021] When the damaged edge site found through the sink network element or source network element is not the corresponding new source network element or sink network element, route calculation is performed on the ports of the new source network element or sink network element and the damaged edge site to form a new local route.

[0022] In combination with the first aspect, in one embodiment, when there are multiple cutover points for an atomic network service, pathfinding is directly performed according to the damaged edge site corresponding to each cutover point to create a new service.

[0023] In combination with the first aspect, in one embodiment, when there are multiple cutover points for an atomic network service, a new service is created sequentially and individually based on the damaged edge site of each cutover point.

[0024] In combination with the first aspect, in one embodiment, after the subnet service is partially damaged and discretized at the cutover point of the atomic network service to obtain damaged local service and / or single-station service, it also includes: recording the service time slot sequence of the atomic network service.

[0025] In combination with the first aspect, in one embodiment, when multiple services exist on an optical fiber, local damage discretization is performed on the multiple services on the optical fiber;

[0027] Based on the service time slot order of the atomic network services and the damaged edge sites of each service, new services for splicing are created one by one.

[0028] In combination with the first aspect, in one embodiment, when multiple services exist on multiple optical fibers, local damage discretization is performed on the multiple services on different optical fibers respectively;

[0029] Reconnect multiple fibers and identify the damaged edge locations for each service on each fiber;

[0030] According to the service time slot order of the atomic network service and the damaged edge site of each service of each optical fiber, a new service for splicing is created for each optical fiber one by one.

[0035] The service splicing module is used to splice the created new service with the damaged local service and / or single-station service to form a new subnet service.

[0036] The beneficial effects of the technical solutions provided in the embodiments of the present application include at least:

[0037] The telecommunications service cutover method in the present application discretizes the local damage of the subnet service at the cutover point of the atomic network service to obtain the damaged local service and / or single-station service; reconnects the fiber of the port that needs to transmit the service data, and searches for services based on the cutover method of the atomic network service until no service is found, so as to determine the corresponding damaged edge site; creates a new service based on the searched damaged edge site; splices the created new service with the damaged local service and / or single-station service to form a new subnet service.

[0038] This application uses local discrete back-calculation to achieve service cutover, solving the variability and duplication of cutover scenarios. In addition, only the cutover point is discretized, and the back-calculation uses the damaged service instead of discretizing all services into single-station services, which improves the efficiency of discrete back-calculation.

[0056] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0058] In a first aspect, an embodiment of the present application provides a telecommunications service cutover method.

[0059] In one embodiment, referring to Figure 1 As shown, Figure 1 This is a flow chart of an embodiment of the telecommunications service cutover method of this application. Figure 1 As shown, the telecommunications service cutover method includes:

[0060] S1. Perform local damage separation of subnet services at the cutover point of the primary network service to obtain damaged local services and / or single-station services;

[0061] In step S1, the service is mainly damaged to complete the partial damage of the atomic network service. The undamaged continuous network element sites maintain the original route to form a damaged local route, and the damaged network element site and single network element are damaged into a single-station service; if there are multiple subnet services on the port, multiple subnet services can be partially damaged at the same time, and the corresponding source network element, destination network element and damaged local service information are recorded.

[0062] It is worth noting that, in this embodiment, when performing service cutover, it is only necessary to perform partial damage to the subnet service at the cutover point of the primary network service, thereby improving the efficiency of subsequent discrete inverse calculation.

[0063] S2. Reconnect the fiber to the port that needs to transmit service data and search for services based on the atomic network service cutover method until no services are found, thereby determining the corresponding damaged edge site;

[0064] In step S2, according to the needs of cutover, the fiber is reconnected. In the physical environment, the ports that need to transmit service data are connected with fibers, and corresponding fiber connection operations are performed on the network management.

[0065] It is worth noting that there are two scenarios for service search based on the atomic network service cutover method:

[0066] When the cutover point is not the source network element or sink network element of the atomic network service, the source network element and sink network element based on the atomic network service start service search respectively; when the cutover point is the source network element or sink network element of the atomic network service, the corresponding sink network element or source network element based on the atomic network service starts service search.

[0067] In other words, when the cutover point is the source NE of an atom-based service, only the corresponding sink NE based on the atom-based service needs to be searched. The same applies to the sink NE of an atom-based service. For batch searches of multiple services, only the service search needs to be performed in a loop.

[0068] S3: Create a new service based on the discovered damaged edge sites.

[0069] It is worth noting that if the cutover point is not the source NE or sink NE of the atomic network service, then:

[0070] When the damaged edge sites searched through the source network element and the sink network element are different network elements, the routing calculation is performed on the ports of the two network elements of the damaged edge site to form a new local route; when the damaged edge sites searched through the source network element and the sink network element are the same network element and there is old business, the old business is deleted and the port of the damaged edge site is used to create a new single-station cross business; when the damaged edge sites searched through the source network element and the sink network element are the same network element and there is no old business, the port of the damaged edge site is directly used to create a new single-station cross business.

[0071] If the cutover point is the source or sink NE of the original network service, then:

[0072] When the damaged edge site found by the sink NE or source NE corresponds to a new source NE or sink NE, a new single-site cross-connect service is created directly using the port of the damaged edge site.

[0073] When the damaged edge site found through the sink network element or source network element is not the corresponding new source network element or sink network element, route calculation is performed on the ports of the new source network element or sink network element and the damaged edge site to form a new local route.

[0074] To create new services in batches for multiple services, it is only necessary to loop through the above two steps (steps S2 and S3) based on each damaged subnet service and create corresponding services based on the original time slots.

[0075] S4. Splice the created new service with the damaged local service and / or single-station service to form a new subnet service.

[0076] Through the above steps, the damaged local services and / or single-station services found are spliced with new single-station services or new subnet local services to form new subnet services.

[0077] For multiple services, batch services are reverse calculated, cyclically calculated, and connected according to time slots to form new subnet services.

[0078] According to the above steps, the service cutover can be completed. And as long as the new service has not been created (before step S3), after the fiber connection is restored, the service back calculation step can be used directly to complete the restoration of the old service.

[0079] The following takes the ODUK service as an example to further illustrate the above steps through two scenarios: port cutover and network element cutover. It is worth noting that the cutover solution in this application is not limited to the ODUK service, but is also applicable to other telecommunications services, such as SDH services, OTN services, and PTN services.

[0080] Port cutover:

[0081] like Figure 2 A subnet ODUK service (ABCD) is formed by NEs A, B, C, and D. Due to service needs (for example, port 1 of NE C is broken), the ODUK service on NE C needs to be cut over.

[0082] Step 1: Through the fixed-point damage discretization of network element C, the following Figure 3 The damaged local service ODUK_1(AB), the single-site ODUK service of network element C and network element D;

[0083] Step 2: Unplug the optical fiber on port 1 of network element C and plug it into port 3 of network element C, thus forming Figure 4 Fiber diagram of damaged business;

[0084] Step 3: Search for services from the source and sink network elements of the primary network services respectively;

[0085] The search starts from source NE A and finds the old damaged local service ODUK_1(AB). Then, the search reaches port 3 of NE C through the fiber connection of NE B. Since port 3 of NE C has no service, the search stops.

[0086] Then the search starts from the sink network element D and finds port 2 of the opposite network element C with the corresponding fiber connection of the single-station crossover of network element D. Since the network element C port 2 is the old service and the crossover port 1 of network element C port 2 has no fiber connection, the search stops.

[0087] It should be noted that the source NE is the network node that sends data, and the sink NE is the network node that receives data. If source NE A is the cutover point, the search starts at NE B. The same applies if the sink NE is the cutover point.

[0088] Step 4: Source NE A and sink NE D simultaneously search for NE C. NE C's single-site service cannot form a subnet service. Therefore, the old ODUK cross-connection of NE C needs to be deleted, and a new ODUK cross-connection between port 3 and port 2 of NE C needs to be created.

[0089] Step 5: Through the damaged local service ODUK_1(AB), the new ODUK of network element C and the ODUK service of network element D, the following Figure 5 New subnet ODUK service (ABCD).

[0090] Network element cutover:

[0091] like Figure 2 A subnet ODUK service (ABCD) is formed by network elements A, B, C, and D. Due to service needs (for example, network element C is decommissioned), the ODUK service on network element C needs to be cut over.

[0092] Step 1: Through the fixed-point damage discretization of network element C, the following Figure 3 The damaged local service ODUK_1(AB), the single-site ODUK service of network element C and network element D;

[0093] Step 2: Adjust the fiber connection between network element C and network element B to the fiber connection between network element B and network element E, and adjust the fiber connection between network element C and network element D to the fiber connection between network element D and network element F, thus forming the following Figure 6 Fiber diagram of damaged business;

[0094] Step 3: Search for services from the source and sink network elements of the primary network services respectively;

[0095] The search starts at source NE A and finds the old damaged local service ODUK_1(AB). Then, the search reaches NE E through the fiber connecting NE B. However, since there is no service on the fiber connecting NE E, the search stops.

[0096] Then the search starts from the sink network element D, and the opposite network element F corresponding to the fiber connection of the single-site cross of network element D is found. Since there is no service on network element F, the search stops.

[0097] Step 4: Since the two network elements found by searching the source network element A and the sink network element D are different, in order to form a complete subnet service, it is necessary to perform routing calculation on the network element E and the network element F, and obtain the following: Figure 7 Local routing service ODUK_N(EF)

[0098] Step 5: The following is formed by using the damaged local service ODUK_1(AB), the newly calculated local routing service ODUK_N(EF) and the ODUK service of network element D: Figure 8 New subnet ODUK service (ABEFD).

[0099] Business batch:

[0100] like Figure 9 For the K-segment subnet ODUK on the optical fiber, it is necessary to perform port cutover on network element C. The steps are as follows:

[0101] Step 1: See Figure 10 As shown, all services on port 1 of network element C are partially broken, forming K local ODUK routes from network element A to network element B, K single-site ODUK routes of network element C, and K single-site ODUK routes of network element D, and recording the corresponding relationship of the K original ODUK services;

[0102] Step 2: Adjust the fiber connection to connect NE B to port 3 of NE C.

[0103] Step 3: Loop through the original K subnet ODUK services, searching for service routes from the source to the sink, and find the damaged edge site for each service. The search end rule is the same as the judgment end rule above.

[0104] Step 4: Delete the old service on NE C, loop through the search results from step 3, create new services, and create the new cross-connect services of NE C on ports 3 and 2 in a one-to-one correspondence based on the time slots of the old services.

[0105] Step 5: Combine the K damaged local services between NE A and NE B, the K newly built single-station services on NE C, and the K single-station services on NE D into subnet services according to the time slots to form Figure 11 The new K ODUK services run from network element A to network element B, then to network element C, and finally to network element D.

[0106] Business fiber batch:

[0107] like Figure 12 As shown in the figure, it is necessary to perform service cutover on the network element C1, which has multiple fibers and multiple ODUKs on each fiber. The steps are as follows:

[0108] Step 1: Perform service damage on each fiber on network element C1, generating multiple damaged local services and multiple damaged single-station services, and record the corresponding relationship between the damage of multiple services on each fiber;

[0109] Step 2: See Figure 13As shown, all the fibers on network element C1 are adjusted to network element C2;

[0110] Step 3: Loop through the multiple services that originally passed through network element C1, perform service route searches from the source to the destination, and find the broken edge connection point of each service. The search end rule is the same as the judgment end rule described above.

[0111] Step 4: Since there is no service on the adjusted NE C2, create the corresponding ODUK service cross-connection on NE C2 based on the search result port and the timeslot of the old service.

[0112] Step 5: Splice the damaged services in each record to form multiple corresponding services passing through network element C2, thereby completing the service replacement of the entire network element.

[0113] In addition, for the case where the cutting point is the source network element and the sink network element of the atomic network service, take the cutting point as the source network element of the atomic network service as an example, see Figure 14 As shown, you can first select cutover point A and then disperse the original ODUK subnet service into a local BCD service without a source NE. Since there is no source NE, the local service BCD can be used to find NE B from sink NE D, and then find the remote NE A2 through NE B.

[0114] See also Figure 15 As shown, if A2 is selected as the new source NE, since the source NE and the found new NE are the same NE, a single-site service for the A2 NE can be directly created, and then combined with the local service BCD to form a new A2-BCD subnet OUDK service.

[0115] See also Figure 16 As shown, if the new network element A1 is selected as the source network element, since A1 and A2 belong to different new network elements, A1 and A2 can be directly used for local routing to find the path A1-A2. Finally, the local route BCD and the local route A1-A2 can be used to form a new subnet ODUK route A1-A2-BCD.

[0116] In addition, when there are multiple cutover points for atomic network services, two methods can be used to handle them:

[0117] First, pathfinding is performed directly based on the damaged edge sites corresponding to each cutover point to create new services.

[0118] Specifically, if B and F need to be cut over in the atomic network service ABCDEFG, if the new service does not need to pass through the CDE network elements, the first method can be used without worrying about where the route passes. As long as AG is connected, the next network element, such as X1, can be found through A, and the next network element X2 can be found through G. Then, X1 and X2 can be directly found, and finally a new A-X1-X2-G route is formed.

[0119] The second approach is to sequentially create new services for each damaged edge site at each migration point. This is equivalent to the sequential processing described above. For example, if the service passes through CDE, you can first migrate the service to A-X1-CDEFG, then migrate the service to A-X1-CDE-X2-G, and finally complete the migration to B and F.

[0120] The same applies to the case where both the source network element and the sink network element need to be cut over, and the above two methods can also be used for processing, which will not be described in detail in this embodiment.

[0121] To sum up, the telecommunications service cutover method in the present application discretizes the local damage of the subnet service at the cutover point of the atomic network service to obtain the damaged local service and / or single-station service; reconnects the fiber of the port that needs to transmit the service data, and searches for the service based on the source network element and the destination network element of the atomic network service until no service is found, so as to determine the corresponding damaged edge site; creates a new service based on the damaged edge site searched through the source network element and the destination network element; splices the created new service with the damaged local service and / or single-station service to form a new subnet service.

[0122] This application uses local discrete back-calculation to achieve service cutover, solving the variability and reusability of cutover scenarios. In addition, only the cutover point is discretized, and the discrete back-calculation reuses the locally damaged services instead of discretizing all of them into single-station services, which improves the efficiency of discrete back-calculation.

[0123] In a second aspect, an embodiment of the present application provides a telecommunications service cutover device.

[0124] In one embodiment, referring to Figure 17 As shown, Figure 17 This is a structural block diagram of an embodiment of the telecommunications service cutover device of this application. Figure 17 As shown, the telecommunication service cutover device includes:

[0125] A damage discrete module is used to perform local damage discreteness on subnet services at the cutover point of the atomic network service to obtain damaged local services and / or single-station services;

[0126] The service search module is used to reconnect the fiber of the port that needs to transmit service data and search for services based on the cutover method of the atomic network service until no service is found, so as to determine the corresponding damaged edge site;

[0127] A service creation module that creates new services based on the discovered damaged edge sites;

[0128] The service splicing module is used to splice the created new service with the damaged local service and / or single-station service to form a new subnet service.

[0129] Furthermore, in one embodiment, the service search module performs service search based on the cutover mode of the atomic network service, including:

[0130] When the cutover point is not the source NE and sink NE of the atomic network service, the source NE and sink NE based on the atomic network service start service search respectively;

[0131] When the cutover point is the source network element or sink network element of the original network service, the corresponding sink network element or source network element based on the original network service starts to search for the service.

[0132] Furthermore, in one embodiment, the service creation module creates a new service based on the damaged edge site found through the source network element and the sink network element, including:

[0133] If the cutover point is not the source NE or sink NE of the atomic network service, then:

[0134] When the damaged edge sites found by the source and sink NEs are different NEs, route calculation is performed on the ports of the two NEs at the damaged edge site to form a new local route.

[0135] If the damaged edge site found by the source and sink NEs is the same NE and an old service exists, delete the old service and create a new single-site cross-connect service using the port of the damaged edge site.

[0136] When the damaged edge site found by the source NE and the sink NE is the same NE and no old service exists, a new single-site cross-connect service is created directly using the port of the damaged edge site.

[0137] Furthermore, in one embodiment, the service creation module creates a new service based on the damaged edge site found through the source network element and the sink network element, including:

[0138] If the cutover point is the source or sink NE of the original network service, then:

[0139] When the damaged edge site found by the sink NE or source NE corresponds to a new source NE or sink NE, a new single-site cross-connect service is created directly using the port of the damaged edge site.

[0140] When the damaged edge site found through the sink network element or source network element is not the corresponding new source network element or sink network element, route calculation is performed on the ports of the new source network element or sink network element and the damaged edge site to form a new local route.

[0141] Furthermore, in one embodiment, when there are multiple cutover points for an atomic network service, the service creation module is configured to directly perform pathfinding according to the damaged edge site corresponding to each cutover point to create a new service.

[0142] Furthermore, in one embodiment, when there are multiple cutover points for an atomic network service, the service creation module is configured to sequentially create a new service based on the damaged edge site of each cutover point.

[0143] Furthermore, in one embodiment, after performing local damage discretization of subnet services at the cutover point of the atomic network service to obtain damaged local services and / or single-station services, the damage discretization module is further used to record the service time slot sequence of the atomic network service.

[0144] Furthermore, in one embodiment, when there are multiple services on an optical fiber, the damage discretization module is used to perform local damage discretization on the multiple services on the optical fiber;

[0145] The service search module is further used to determine the damaged edge site of each service after the fiber is reconnected;

[0146] The service creation module is used to create new services for splicing in a one-to-one correspondence based on the service time slot order of the atomic network services and the damaged edge sites of each service.

[0147] Furthermore, in one embodiment, when there are multiple services on multiple optical fibers, the damage discretization module performs local damage discretization on the multiple services on different optical fibers respectively;
