Technical Field

The invention relates to the technical field of network management and control of a telecommunication transmission network, in particular to a scene type cut-over method and a scene type cut-over system based on virtual components.

Background

In the network management and control process of a telecommunication transmission network, the topology of the existing network is often changed, for example, network elements, single disks and connecting fibers are increased or decreased for capacity expansion and reduction; for example, nodes on the ring are increased or decreased for reconstructing the convergence ring; such as replacement of a network element, single disk, for new devices to replace old devices. In the above network maintenance process, the current network topology often has the telecommunication services running, and in order to minimize the range of the telecommunication services affected by the topology change, the telecommunication services need to be cut over. The telecommunication service cutover means that local telecommunication services are adjusted to the greatest extent to adapt to a new topology, and the new telecommunication services are prevented from being reconfigured, so that the opening time of the telecommunication services on the new topology is saved.

The main processing procedure in the prior art is to use a database for backup, and if an error occurs in the cutover process, topology and telecommunication service are rolled back to the backup time point; secondly, the topology is changed to cause the damage of the telecommunication service, and then the telecommunication service is repaired according to the new topology. The problem of doing so is that the database backup in the first process is a whole backup mode, the efficiency of the backup and rollback processes is not high, multiple backups exist under the operation of multiple users, and the version problem among the multiple backups also exists; in the second process, the topology is changed first and the telecommunication service is repaired later, so that the damaged telecommunication service can be stored in the database until the damaged telecommunication service is repaired, and fragmentation of the telecommunication service is easily caused, namely the unrepaired damaged telecommunication service always exists on certain network elements, and resource waste is caused.

The embodiment of the invention provides a scene type cutting and connecting method based on a virtual component, which comprises the following steps:

storing the telecommunication service to be adjusted into a transaction cache, and adjusting the telecommunication service according to the topological component and the virtual component;

when no error occurs in the adjustment, submitting a transaction cache, storing the adjusted telecommunication service to a database and changing the topology, wherein the database refers to a database which is mentioned in the background technology and is used for backing up the topology corresponding to the telecommunication service; and when the error is adjusted, rolling back the transaction cache, and restoring the telecommunication service to the state before the adjustment without changing the topology.

When the telecommunication service to be adjusted is decomposed into a plurality of basic scenes, the sequence of cutting each basic scene is determined according to the sequence of each basic scene required by realizing a complex scene.

As a preferred embodiment, for a current basic scenario, storing a topology component in a transaction cache, and creating a virtual component in the transaction cache specifically includes the following steps:

As a preferred embodiment, submitting a transaction cache, saving the adjusted telecommunication service to a database and changing the topology, specifically comprising the steps of:

As a preferred embodiment, rolling back the transaction cache, before restoring the telecommunication service to the adjusted state, does not change the topology, specifically includes the following steps:

restoring the telecommunication service before adjustment from the transaction cache, namely replacing the topology corresponding to the telecommunication service in the database with the topology component and the virtual component corresponding to the telecommunication service before adjustment according to the corresponding relation between the topology component and the virtual component in the transaction cache;

The following description and the accompanying drawings further illustrate the implementation of the embodiments of the present invention.

Referring to fig. 1, the method for virtual component-based scene-based cutover specifically includes the following steps:

step S1, decomposing the complex scene into a plurality of basic scenes, and sequentially cutting each basic scene;

step S2, establishing a transaction cache of the topological component and the virtual component for the current basic scene;

step S3, for the current basic scene, establishing the transaction buffer of the telecommunication service, and then adjusting the telecommunication service.

Step S4, if no error occurs, turning to S5; if the above process is erroneous, go to S6;

step S5, if the basic scene still exists, returning to S2 to continue execution; if there is no basic scene, go to S7;

step S6, rolling back the transaction buffer, before the telecommunication service is restored to the adjustment, not changing the topology; and ending the flow.

Step S7, submitting the transaction buffer, storing the adjusted telecommunication service in a database, and changing the topology correspondingly; and ending the flow.

through the analysis of the real cutover scene, the complex scene can be formed by combining several basic scenes in sequence. As shown in the following table:

(the routing formats in the third example column in table 1 are uniform, the first being alphabetical to indicate the network element, the second being numeric to indicate the port, - > to indicate the fibre attachment, -' to indicate the unknown route after change. for example, B1B2 indicates port 1 and port 2 of network element B.

TABLE 1

The actual cutover scene is complex, but can be decomposed into the basic scene. For example, an existing device needs to be added to the convergence ring, and the capacity of the device needs to be increased; the method can be decomposed into 1) 'adjustment of NNI ports on two sides between network elements', adding equipment into a convergence ring firstly, and 2) 'integral replacement of equipment', and replacing the equipment with new equipment with larger capacity.

for the basic scenario, the related topology components, virtual components and the relationship between them are determined, and the type of the virtual components is virtual single disk, virtual fiber, as shown in the following table:

TABLE 2

Taking an overall replacement of the device as an example, when a telecommunication service a1- > B1B2- > C1 is known, a network element B is adjusted to be a network element D, ports have one-to-one equivalence, and a new route is changed to a1- > D1D2- > C1, then the form of a transaction cache is as follows:

topological components: < user ID, < A1- > B1, B2- > C1>

Virtual components: < user ID, < A1- > D1, D2- > C1>

Topological component and virtual component relationships: < user ID, < (A1- > B1, A1- > D1), (B2- > C1, D2- > C1) >

Referring to fig. 2, step S2 specifically includes the following steps:

step S21, obtaining the topological components in the current basic scene, and adding the topological components in the topological component set in the transaction cache < user ID, topological component set >;

in the step, the topology components are recorded in the transaction cache in the form of the user ID, and other users cannot modify the topology components, so that the access mutual exclusion of the topology components is ensured.

The two fibers < user ID, < a1- > B1, B2- > C1> >, a1- > B1 and B2- > C1 in the above example are locked and cannot be modified by other users.

Step S22, acquiring the virtual components in the current basic scene, and adding the virtual components in the virtual component set in the transaction cache < user ID, virtual component set >;

in the step, the virtual component is recorded in the transaction cache in the form of the user ID, and the user can only use the virtual component recorded in the transaction cache by himself and cannot access the virtual components created by other users, so that the isolation of the virtual components is guaranteed.

The < user ID, < A1- > D1, D2- > C1> >, A1- > D1 and D2- > C1 in the above example are two virtual fibers, which exist only in the transaction cache and are only accessible by the present user.

Step S23, obtaining the corresponding relationship between the topological component and the virtual component in the current basic scene, and adding the corresponding relationship between the topological component and the virtual component in the transaction cache < < user ID, < topological component ID, virtual component ID > set >.

In this step, the correspondence relationship between the topology component and the virtual component, that is, the relationship in which the topology component can be replaced by the virtual component is recorded in the form of the user ID. The topological components and the virtual components may be in a one-to-one correspondence relationship, or one topological component may correspond to a plurality of virtual components, or a plurality of topological components may correspond to one virtual component. For example, in the LAG port processing process, two connected fibers may be formed corresponding to the original connected fibers; there is also possibility that a plurality of original continuous fibers become a continuous fiber.

As in the above example, < user ID, < (a1- > B1, a1- > D1), (B2- > C1, D2- > C1) >, topological component a1- > B1 corresponds to virtual component a1- > D1; the topological component B2- > C1 corresponds to the virtual component D2- > C1.

In this step, the telecommunications traffic is originally on the topology component, and the telecommunications traffic is adjusted to the virtual component since the topology component needs to be replaced by the virtual component after the cutover. If no virtual components are created in the basic scenario, the telecommunications traffic does not need to scale to virtual components, but to other topological components.

The teleservice a1- > B1B2- > C1 in the above example needs to be adjusted from the topological component a1- > B1, B2- > C1 to the virtual component a1- > D1, D2- > C1.

Referring to fig. 3, step S3 specifically includes the following steps:

s31, storing the telecommunication service to be adjusted in the basic scene into a transaction cache;

in this step, the telecommunication service is saved to the transaction cache before the corresponding telecommunication service is processed, according to the specific basic scenario. Telecommunication services here refer to those telecommunication services that are affected by modifying topological components or avoiding points of failure in the basic scenario.

The teleservice a1- > B1B2- > C1 in the above example is saved into the teleservice's transaction cache as follows:

< user ID, < A1- > B1B2- > C1>

S32, if the basic scene has no virtual components, turning to S33, otherwise, turning to S34;

in this step, according to table 1, it is determined whether there is a virtual component in the basic scene, and then a jump is made.

The transaction cache of the virtual component in the above example is not empty and therefore a jump is made to S34.

And S33, adjusting the telecommunication service according to the topological component on the real physical topology, and ending the process.

In this step, the corresponding basic scenario does not need to create a virtual component, but only needs to adjust the telecommunication service according to the real physical topology, that is, the telecommunication service is adjusted from the original topology component to other topology components.

S34, adjusting the telecommunication service from the topological component to the virtual component according to the corresponding relation between the topological component and the virtual component in the transaction cache;

in this step, the corresponding basic scenario needs to create a virtual component, and the telecommunication service is adjusted from the original topological component to the virtual component, that is, the topological component data in the telecommunication service is modified and replaced with the virtual component data according to the corresponding relationship.

As in the above example, telecommunication service a1- > B1B2- > C1, the topology component in the above example is replaced by a virtual component according to the relationship between the topology component and the virtual component, namely, user ID, < (a1- > B1, a1- > D1), (B2- > C1, D2- > C1), so as to form a new telecommunication service a1- > D1D2- > C1.

And S35, generating the configuration data of the telecommunication service on the virtual component, and ending the process.

In this step, the telecommunications service needs to generate the corresponding configuration on the virtual component, just as on the original topological component.

The new teleservice a1- > D1D2- > C1 in the above example generates configuration data for this teleservice on virtual components a1- > D1, D2- > C1.

in this step, it is determined whether there is an error in the process of S2-S3, and if there is an error, all transaction caches of the user need to be rolled back; the transaction caches of other users are not processed, and the users are isolated.

in this step, it is determined whether the basic scenes constituting the complex scene have been executed, and the basic scenes are executed in sequence, that is, the complex scene is executed.

In this step, the user returns to the state before the user performs the cutover by rolling back the transaction cache, and the influence range is limited only inside the cutover scene performed by the user.

Referring to fig. 4, step S6 specifically includes the following steps:

s61, recovering the telecommunication service before adjustment from the service cache < user ID, telecommunication service set >;

in this step, the adjusted telecommunications traffic of the user is retrieved from the traffic cache and the telecommunications traffic adjusted to the virtual component is restored to the adjusted telecommunications traffic.

In the above example, the teleservice before the adjustment is found from the teleservice transaction cache < user ID, < a1- > B1B2- > C1>, and the new teleservice a1- > D1D2- > C1 is restored to teleservice a1- > B1B2- > C1.

S62, clearing the configuration data of the telecommunication service on the virtual component;

in this step, the configuration data of the telecommunication service on the virtual components is completely cleared.

In the above example, the configuration data of the telecommunications traffic on virtual component A1- > D1, D2- > C1 is cleared.

S63, clearing the telecommunication service before adjustment from the service cache;

in this step, the relevant teleservice recorded by the user in < user ID, teleservice set > is cleared.

In the above example, the teleservice a1- > B1B2- > C1 before adjustment in the teleservice transaction cache < user ID, < a1- > B1B2- > C1 >.

S64, clearing the topological components, the virtual components and the relations among the topological components and the virtual components from the transaction cache.

In this step, the transaction cache associated with the user in < user ID, topological component set >, < user ID, virtual component set >, < user ID, < topological component ID, virtual component ID > set > is purged.

In the above example, the transaction cache of the topology component is cleared for a1- > B1 and B2- > C1 in < user ID, < a1- > B1, B2- > C1 >; clearing the transaction cache of the virtual component from < user ID, < A1- > D1, D2- > C1> > A1- > D1 and D2- > C1;

the transaction cache of the relation between the topological component and the virtual component is cleared for (A1- > B1, A1- > D1) and (B2- > C1, D2- > C1) in < user ID, < (A1- > B1, A1- > D1), (B2- > C1, D2- > C1).

Referring to fig. 5, step S7 specifically includes the following steps:

s71, storing the adjusted telecommunication service to a database;

in this step, the telecommunication service tuned to the virtual component is saved to the database, i.e. the new telecommunication service after the topology component in the telecommunication service is replaced by the virtual component is saved to the database.

In the above example, the new teleservice A1- > D1D2- > C1 is saved to the database.

S72, converting the virtual component into a topological component and storing the topological component in a database;

in this step, the virtual components are present in the transaction cache and there are no virtual components in physical topology. The conversion process of this step is to convert the data of the virtual component into the data of the topological component, add the data to the physical topology, and delete the original topological component. Since the virtual components are the same as the basic data of the topology components, such as network elements, single disks and fiber connections, there is no big problem in data conversion.

In the above example, virtual components A1- > D1, D2- > C1 are saved to the database and the topological components A1- > B1, B2- > C1 are deleted from the database.

S73, clearing the telecommunication service before adjustment from the service cache;

S74, clearing the topological components, the virtual components and the relations among the topological components and the virtual components from the transaction cache.
