On the contrary, it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims. It should be noted that the method steps described herein may be implemented by any functional block or functional arrangement, and that any functional block or functional arrangement may be implemented as a physical entity or a logical entity, or a combination of both.
In order that those skilled in the art will better understand the present invention, the following detailed description of the invention is provided in conjunction with the accompanying drawings and the detailed description of the invention.
Note that: the example to be described next is only a specific example, and does not limit the embodiments of the present invention necessarily to the following specific steps, values, conditions, data, orders, and the like. Those skilled in the art can, upon reading this specification, utilize the concepts of the present invention to construct more embodiments than those specifically described herein.
The embodiment of the invention provides a method for adjusting OTN protection service without loss, which comprises the following steps:
selecting unprotected service to be adjusted, selecting type, protection level and attribute of protected service to be created, and creating protection for the selected unprotected service.
Preferably, the method further comprises the steps of: and selecting the service with protection to be adjusted, and deleting protection for the selected service with protection. If the current path is a protection path, the method for deleting protection for the protected service can be applied only by switching roles of the protection path and the working path, setting the original protection path as the current working path and setting the original working path as the current protection path.
Preferably, the attributes of the protection service include a protection mode, a return mode, a hold-off time, and a recovery waiting time.
Preferably, as shown in fig. 1, the implementation steps for adjusting unprotected traffic to protected traffic are as follows:
s11, directly selecting unprotected service to be adjusted on the network management interface, and providing a menu item for directly adding a protection path in the shortcut menu after right key click for user selection.
S12, selecting a type of a protection service, such as OCH1+1, OCH 1: 1, ODUK1+1, ODUK 1: 1 and C L IENT1+1, selecting a protection level, determining a level of the selectable protection service according to a current level of a selected working path to which a protection path is to be added, where the protection level may be a level of the current service or a level of a parent layer thereof, where, if there are 3 levels of services on a port of an original unprotected service, the service is an ODU1, an ODU2, or an ODU3, when a protection is created on a service of an ODU2, the protection level may be an ODU2 or an ODU3, when a protection is created on a service of an ODU1, the level may be an ODU1, an ODU2, or an ODU1 service addition protection, and when the protection level is selected as an ODU1, the protection level is the same as an ODU2, the service addition protection level is selected as an ODU1, and when a working path of an ODU is a service cross protection port, a 2, a service is a service port waiting for a service restoration service, a service cross protection port, a service node is a service node 2, a service node under a service waiting time map 2, a service node under a protection node under a similar to be a protection time map 2, a service node under a service cross protection node under a protection service node under a protection time point 368627, a protection node under a service node under a protection time point 36867, a service node under a.
S13, sequentially creating each layer of ODUK service from large granules to cross granules according to the service level to be created on the protection service port. After the ODUK service identical to the selected protection layer level is created, it is necessary to recursively analyze whether a sub-layer service still exists in the working service corresponding to the protection layer level and the sub-layer thereof, and then sub-layer services corresponding to the working service ODUK objects one to one are created under the protection ODUK object identical to the protection layer level. For example, the service hierarchy on the port of the original unprotected service is 1/OUD 3-1/ODU 2-1, ODU 4-1/ODU 3-2, ODU 4-1/OUD 3-1/ODU 2-2, that is, there is one ODU4 service on the port, 2 ODU3 sub-layer services on the ODU4 service, and 2 ODU2 services on the ODU 3-1 service. When adding protection to the service selected as OUD4, after creating the service of the ODU4 on the protection port, 2 corresponding ODU3 services and two ODU2 services need to be created at the same time. When the service with the ODU 3-2 is selected to add protection, and the protection level selects the ODU3, the ODU4 and ODU3 services may be created on the protection port. When the service with the ODU3 ═ 1 is selected to add protection, and the protection layer level selects the ODU3, after the ODU4 and ODU3 services are created on the protection port, 2 ODU2 services also need to be created to correspond to the sublayer service with the ODU3 ═ 1 one to one.
And S14, creating a protection relation object, and associating the created work service and the protection service object which are in the same layer with the protection layer. And simultaneously recording the information of the protection relation object in the attributes of the working service and the protection service object so as to indicate that the working service is the service with protection.
S15, when the protection is large-grained and the protection is small-grained, sub-layer services corresponding to the sub-layer services under the protection service are correspondingly created under the protection service, so that when the protection is switched, all the small-grained services are switched, and therefore, the brother relationship of the sub-layer of the protection service needs to be recorded in the attribute of the sub-layer of the protection service, and the brother relationship of the sub-layer of the protection service needs to be recorded in the attribute of the sub-layer of the protection service.
And S16, when the network management state of the original unprotected service is the activated state, the state of the unprotected service needs to be adjusted to be a partially activated state, and the user is prompted that the service needs to be downloaded again after being adjusted, so that the adjusted protection is effective. When the network management state of the original unprotected service is partially activated or not activated, the state of the unprotected service does not need to be changed, because in the state of non-activation or partial activation, a user needs to activate the service to enable all functions of the service to take effect.
S17, when the user activates the service, it is necessary to store the relevant configuration data related to the service and the protection relationship object of each layer into the table of the database in table 1, that is, record the corresponding relationship between the service ID and the configuration data, so that the associated configuration can be taken out after the service is deleted, and then the configuration is cleared in the device.

Preferably, as shown in fig. 2, the implementation steps for adjusting protected services to unprotected services are as follows:
s21, directly selecting the service with protection to be adjusted on the interface of the network management, and providing a menu item for directly deleting the protection path in the shortcut menu after clicking the right key for the user to select when the state of the network management with the protection service is activated or not activated.
S22, obtaining the working path and the protection path through the protection relationship object, removing the relation among the working path, the protection path and the protection relationship object, deleting the protection relationship object, and simultaneously recording the deletion relation between a working service ID and the deleted protection relationship object ID, so that the ID of the deleted object corresponding to the working service ID can be found through the data when the working service is downloaded.
S23, recursively acquiring any sublayer service of the working service, clearing the brother relation recorded by the sublayer service, and simultaneously recording the deletion relation between each sublayer service and the protection sublayer service one by one. If the hierarchy of the working service is ODU2 and the next service of 3 sub-layers is ODU1, the sibling relationship associated with the service of 3 sub-layers ODU1 needs to be cleared, and a deletion relationship between the service ID of the deletion sub-layer and the service ID of the working service sub-layer is generated. If the working service has no sub-layer service, the protection level is the same as the cross-grain, and the operation of clearing the sibling relation is not needed.
S24, if the upper layer of the working service includes a service layer, it indicates that the protection level is not the largest particle, and meanwhile, the upper layer of the protection service also includes a service layer, when the service layer of the protection service does not include any other sub-layer except the current protection service, the protection service also needs to be deleted, and when the ODUK service at the highest layer needs to be deleted, the OTUK service also needs to be deleted. If the protection level is the ODU2, the upper layer of the working service ODU2 has two layers of service ODU3 and ODU4, the upper layer of the protection service ODU2 also has two layers of service ODU3 and ODU4, and when there is no other service in the protection service layer ODU3, deletion is required, when there is no other sub-layer service in the sub-layer of the ODU4 service layer except the current ODU3, deletion is required, and when the ODU4 needs to be deleted, the service layer ODUT thereof also needs to be deleted. And respectively recording the association relations between the deleted protection service and the parent layer and between the working service and the parent layer.
S25, deleting the sub-layer protection path, the protection path, and the protection parent layer path, and releasing the resources occupied by each layer of path, if the network management status of the protection service before deletion protection is active, the recorded corresponding relationship information between the deleted protection service ID and the associated working service ID needs to be stored in the database table shown in table 2.

And S26, when the network management state of the original protected service is activated, modifying the state of the unprotected working path after adjustment into partial activation, and prompting the user to download the service.
S27, when the user activates or deactivates the adjusted service, finding the deleted service ID associated with the unprotected service ID in the database table 2 through the unprotected service ID to be activated or deactivated, taking out the configuration data of the deleted service ID in the recorded service configuration database table 1, and performing a deletion operation together with the unprotected service. The information recorded in the database tables 1 and 2 is deleted at the same time.
