Background
In operation and maintenance of a PTN (Packet Transport Network) Network, a cutover of PTN traffic is often performed. The traditional cutover plan is composed of cutover groups, the cutover groups directly contain business objects to be cutover, and the business objects often have complex dependency relationship, so that a user must carefully screen the business objects when establishing the cutover plan, and the cutover plan cannot be implemented due to incomplete inclusion of the business objects. Common dependencies are: 1) the dependency relationship between the business object and its auxiliary object, such as: a tunnel and its OAM (Operation Administration and Maintenance) data, a pseudowire and its OAM data. 2) Protection relationships between business objects, such as: protection tunnels and working tunnels, protection pseudowires and working pseudowires. 3) Fixed bearer relationships between business objects, such as: an emulation service and a pseudowire or multi-segment pseudowire carrying it.

The creating module 201 is configured to create one or more cutover groups that constitute a PTN service cutover plan; the adding module 202 is configured to add a pre-cutover unit including a tunnel or a simulation service in each of the cutover groups, and add a post-cutover unit to be used for replacing the pre-cutover unit in a cutover process in each of the cutover groups; the pre-cutting unit and the post-cutting unit are configured in an assembly mode, or the pre-cutting unit and the post-cutting unit are configured in a non-assembly mode, or the pre-cutting unit and the post-cutting unit are configured in an assembly mode and a non-assembly mode.

Fig. 4 is a schematic diagram illustrating a relation among a cutting plan, a cutting group, a cutting pair, and a cutting unit according to an embodiment of the present invention, as shown in fig. 4, including the cutting plan, the cutting group, the cutting pair, a pre-cutting unit, a post-cutting unit, and an unpaired cutting unit. Wherein, the pre-cutting unit and the post-cutting unit can form a cutting pair; the plurality of cutting pairs can form a cutting group, the cutting unit can also be directly added into the cutting group under the condition of no pair, and the plurality of cutting groups can jointly form a cutting plan.
Specifically, the scission units are atomic units that cannot be subdivided during the scission process, and are divided into pre-scission units and post-scission units. The unit before the cutting refers to the service unit existing in the current network before the cutting action is executed, and the unit after the cutting refers to the service unit which is prepared to replace the unit before the cutting in the cutting process and is established in the network management in advance.
The pre-cleft grafting unit and the post-cleft grafting unit may form a cleft grafting pair. The resources released by the pre-cutting unit in the cutting pair can only be pre-supported by the post-cutting unit in the pair, and the other post-cutting units can not be pre-supported. And a cutting pair forms a minimum cutting and replacing action, in the process, the service connection relation represented by the unit before cutting is removed from the equipment and replaced by the service connection relation represented by the unit after cutting, and if an error occurs in the cutting process, the cutting pair automatically rolls back to the state before the cutting operation starts.
A plurality of cutover pairs may form a cutover group. The cutover unit can also be added into the cutover group directly under the condition of no pair, at this time, the resource is shared in the whole cutover group range, that is, the resource released by any unit before cutover in the group can be pre-supported by any unit after cutover in the group. Typically, the tunnel cutover unit/cutover pair and the emulation service cutover unit/cutover pair carried by the tunnel cutover unit/cutover pair are jointly constructed into a cutover group. Because there is a certain dependency relationship between the tunnel with bearer relationship and the emulation service when creating and deleting, for example: the tunnel must be created before the simulation service, and the simulation service must be deleted before the tunnel, so the cutover composition is the actual cutover minimum unit, each cutover pair in the cutover group must be cut over or rolled back, if an error occurs in the cutover process, the whole cutover group automatically rolls back to the state before the cutover operation starts. For the cutover pairs in the cutover group, provided that there is no operational dependency between them, such as: all the pairs are emulation service cutover pairs, or although the tunnel cutover pair and the emulation service cutover pair exist at the same time, the tunnel cutover pair and the emulation service cutover pair do not have a bearing relationship, and then the cutover or rollback can be initiated for a single cutover pair at the moment.
A plurality of cutover groups may together form a cutover plan. The various cutting groups in the cutting plan have no operational interdependence relationship, and the cutting plans are formed by the cutting groups and are more used for the purpose of artificial planning. The cutting or rolling back can be carried out based on the whole cutting plan, and partial cutting groups in the cutting plan can be independently selected to carry out the cutting or rolling back operation.
When the cutting plan is deleted, the whole cutting plan can be deleted, at this time, all cutting groups and cutting units in the cutting plan are cleared, and the cutting unit is restored to the state before the cutting group is added. One or more cutover groups below the cutover plan may be deleted, at which point the cutover group and the post-cutover units in the cutover group are cleared and the pre-cutover units in the cutover group are restored to a state prior to joining the cutover group. Under the condition that no operation dependency relationship exists between the cutting pairs, partial cutting pairs in the cutting group can be deleted independently; in the case of no resource sharing relationship among the cutover units, part of the pre-cutover units in the cutover group can be deleted individually.
In the following, with reference to fig. 6 to 8, a detailed description is given of an implementation of the present invention for creating a cutover plan, where the process of creating a cutover plan roughly includes the following steps:

an adding module, configured to add a pre-cutover unit containing a tunnel or a simulation service in each cutover group, and add a post-cutover unit to be used for replacing the pre-cutover unit in a cutover process in each cutover group, so as to perform cutover or rollback on the created entire PTN service cutover plan, or one or more cutover groups in the PTN service cutover plan, or one or more cutover pairs in the cutover groups of the PTN service cutover plan;
the pre-cutting unit and the post-cutting unit are configured into the cutting pair in an assembly mode, or the pre-cutting unit and the post-cutting unit are configured in a non-assembly mode, or the pre-cutting unit and the post-cutting unit are configured in an assembly mode and a non-assembly mode;
wherein the PTN refers to a packet transport network.
6. The apparatus of claim 5, wherein the cutover group is formed by any one of:
a cutover pair configured in a pairing manner;
a pre-cut unit and a post-cut unit configured in a non-paired manner;
the device comprises a cutting pair configured in a pairing mode, and a pre-cutting unit and a post-cutting unit configured in a non-pairing mode.
7. The apparatus of claim 5, wherein the pre-severance unit and post-severance unit are comprised of either:
OAM configuration of each unprotected tunnel to be cut and connected and/or unprotected tunnels;
each work to be cut-over, protection tunnel and/or work, protection tunnel OAM configuration and/or tunnel protection group;
