DETAILED DESCRIPTION OF THE EMBODIMENTS

[0044] The embodiments of the present disclosure will be described below with reference to the drawings in detail. It is important to note that the embodiments in the present disclosure and characteristics in the embodiments may be freely combined under the condition of no conflicts.

[0045] FIG. 2 is a flowchart of a method for managing an application resource according to an embodiment. The method may include the following steps.

[0046] In a step of S201, an AE located on an application node or a CSE located on an intermediate node sends a node resource creation request to a corresponding registration CSE to request a resource for the application node where the AE is located or the intermediate node where the CSE is located.

[0047] The node resource creation request includes: an AE identity of the AE or a CSE identity of the CSE, a node identity and a type of the resource to be created. The type of the resource to be created may be a node type.

[0048] In a step of S202, the registration CSE creates a node resource for the application node or the intermediate node, and establishes an association relationship between an AE resource which has been created for the AE and the currently created node resource, or establishes an association relationship between a CSE resource which has been created for the CSE and the currently created node resource.

[0049] An attribute of the AE resource includes the AE identity, and an attribute of the CSE resource includes the CSE identity.

[0050] The registration CSE creates a resource of the node type after receiving the resource creation request. A “node identity” attribute may be set for the node resource, and an attribute value of the “node identity” attribute is the node identity carried in the resource creation request.

[0051] In an exemplary embodiment, the step that the registration CSE establishes the association relationship between the AE resource and the currently created node resource includes that:

[0052] the association relationship between the AE resource of which the attribute includes the AE identity and the currently created node resource is established.

[0053] In an exemplary embodiment, the step that the registration CSE establishes the association relationship between the CSE resource and the currently created node resource includes that:

[0054] the association relationship between the CSE resource of which the attribute includes the CSE identity and the currently created node resource is established.

[0055] In an exemplary embodiment, the step that the registration CSE establishes the association relationship between the AE resource and the currently created node resource includes that:

[0056] a value of a “node connection” attribute of the AE resource is set to be the node identity or an address of the currently created node resource.

[0057] In an exemplary embodiment, the step that the registration CSE establishes the association relationship between the CSE resource and the currently created node resource includes that:

[0058] a value of a “node connection” attribute of the CSE resource is set to be the node identity or an address of the currently created node resource.

[0059] In a step of S203, when the AE is located on a new application node or the CSE is located on a new intermediate node in case of node replacement, the AE or the CSE sends a node resource deletion request to the registration CSE.

[0060] The node resource deletion request includes: a node replacement indication, the AE or CSE identity and the address of the replaced node resource.

[0061] In a step of S204, the registration CSE deletes the node resource created for the application node or the intermediate node and the association relationship.

[0062] The registration CSE finds the node resource to be deleted according to the address of the replaced node resource.

[0063] In an exemplary embodiment, the step that the registration CSE deletes the established association relationship includes that:

[0064] the node connection attribute of the AE or CSE resource is deleted, or, the value of the node connection attribute of the AE or CSE resource is set to be null.

[0065] In a step of S205, the registration CSE allocates a replacing node identity, and returns the replacing node identity to the AE or the CSE. The replacing node identity corresponds to the AE identity or the CSE identity.

[0066] In a step of S206, the AE or the CSE sends a node resource creation request to the registration CSE to request a resource for the new application node or the new intermediate node.

[0067] The node resource creation request includes: the replacing node identity, the node identity and the type of the resource to be created.

[0068] In a step of S207, the registration CSE creates a new node resource for the new application node or the new intermediate node, finds a corresponding AE resource or CSE resource according to the replacing node identity, and establishes an association relationship between the AE resource and the currently created node resource, or establishes an association relationship between the CSE resource and the currently created node resource.

[0069] In the technical solution, the registration CSE creates the node resource for the node where the AE or the CSE is located, and establishes the association relationship between the AE resource and the created node resource, or establishes the association relationship between the CSE resource and the created node resource. By virtue of the technical solution, a purpose of associating the AE resource with the node to which the AE resource belongs and associating the CSE resource with the node to which the CSE resource belongs on the registration CSE can be achieved. In addition, in the technical solution, when the node where the AE or the CSE is located is replaced, the AE resource or CSE resource stored in the registration CSE is not deleted, and instead, the association relationship between the replacing node and the AE resource or the CSE resource is established, so that the replacing node may continue using the AE resource or CSE resource before node replacement. In this way, the problem of running data loss under the condition that the application node and/or the intermediate node are/is replaced and the replacing nodes/node are/is expected to reserve running data of the replaced nodes/node is solved.

[0070] FIG. 3 is a module diagram of a registration node for managing an application resource according to an embodiment.

[0071] The registration node includes: a resource management module and a resource association module.

[0072] The resource management module is arranged to, after receiving node resource creation request sent by an AE or a CSE, create a node resource for an application node where the AE is located or an intermediate node where the CSE is located.

[0073] The node resource creation request includes: an AE identity of the AE or a CSE identity of the CSE, a node identity and a type of the resource to be created. The type of the resource to be created may be a node type.

[0074] The resource association module is arranged to establish an association relationship between an AE resource which has been created for the AE and the currently created node resource, or establish an association relationship between a CSE resource which has been created for the CSE and the currently created node resource. An attribute of the AE resource includes the AE identity, and an attribute of the CSE resource includes the CSE identity.

[0075] In an exemplary embodiment, the resource association module is arranged to establish the association relationship between the AE resource which has been created for the AE and the currently created node resource in the following manner:

[0076] establishing the association relationship between the AE resource of which the attribute includes the AE identity and the currently created node resource.

[0077] In an exemplary embodiment, the resource association module is arranged to establish the association relationship between the CSE resource which has been created for the CSE and the currently created node resource in the following manner:

[0078] establishing the association relationship between the CSE resource of which the attribute includes the CSE identity and the node resource.

[0079] In an exemplary embodiment, the resource association module is arranged to establish the association relationship between the AE resource which has been created for the AE and the currently created node resource in the following manner:

[0080] setting a value of a “node connection” attribute of the AE resource to be the node identity or an address of the currently created node resource.

[0081] In an exemplary embodiment, the resource association module is arranged to establish the association relationship between the CSE resource and the currently created node resource in the following manner:

[0082] setting a value of a “node connection” attribute of the CSE resource to be the node identity or an address of the currently created node resource.

[0083] The resource management module is further arranged to, when receiving a node resource deletion request from the AE or the CSE after receiving the node resource creation request sent by the AE or the CSE, delete the node resource created for the application node or the intermediate node and the association relationship. The node resource deletion request includes a node replacement indication, the AE identity or the CSE identity.

[0084] In an exemplary embodiment, the resource management module is arranged to delete association relationship in the following manner:

[0085] deleting the node connection attribute of the AE or CSE resource, or, setting a value of the node connection attribute of the AE or CSE resource to be null.

[0086] The resource management module, besides being arranged to delete the node resource created for the application node or the intermediate node and the association relationship, is further arranged to allocate a replacing node identity to the AE or the CSE, and return the replacing node identity to the AE or the CSE. The replacing node identity corresponds to the AE identity or the CSE identity.

[0087] The resource management module is further arranged to, when receiving a node resource creation request of requesting a resource for a new application node or a new intermediate node from the AE or the CSE after returning the replacing node identity to the AE or the CSE, create a new node resource for the new application node or the new intermediate node, and find a corresponding AE resource or CSE resource according to the replacing node identity.

[0088] The node resource creation request of requesting the resource for the new application node or the new intermediate node includes: the AE identity or the CSE identity, the node identity and the type of the resource to be created.

[0089] In the technical solution, the registration CSE creates the node resource for the node where the AE or the CSE is located, and establishes the association relationship between the AE resource and the created node resource, or establishes the association relationship between the CSE resource and the created node resource. By virtue of the technical solution, a purpose of associating the AE resource with the node to which the AE resource belongs and associating the CSE resource with the node to which the CSE resource belongs on the registration CSE can be achieved. In addition, in the technical solution, when the node where the AE or the CSE is located is replaced, the AE resource or CSE resource stored in the registration CSE is not deleted, and instead, the association relationship between the replacing node and the AE resource or the CSE resource is established, so that the replacing node may continue using the AE resource or CSE resource before node replacement. In this way, the problem of running data loss under the condition that the application node and/or the intermediate node are/is replaced and the replacing nodes/node are/is expected to reserve running data of the replaced nodes/node is solved.
