Problems solved by technology

[0005] (1) The cross-domain service configuration of SPTN equipment requires unified management of equipment from different manufacturers in different domains. At present, the network management and equipment of each manufacturer communicate through private interfaces, and the management data issued by the network management and the status data reported by the equipment All follow the private protocol defined internally by the manufacturer. This protocol can only be used for the communication between the equipment of the same manufacturer and the network management, so it cannot manage the equipment produced by other manufacturers.
Under the current situation, it is very difficult to formulate and promote a set of standard southbound interfaces for network management and equipment interaction among various manufacturers, and it runs counter to the current development trend of network architecture.
[0006] (2) The cross-domain service configuration of SPTN equipment needs to divide the management scope of different domains, and each domain manages internal physical resources. However, the current project does not have the concept of domains. If it is divided by equipment manufacturers, the network management of the same manufacturer All devices are divided into one domain, which is too simple and rough to reflect the advantages of logical hierarchical management of domains
[0007] (3) The cross-domain service configuration of SPTN equipment needs to manage the physical resources between domains. The physical resources between domains mainly refer to the fiber connection and port information between edge devices in different domains. The port fiber connection information between domains is mainly used for Path search when configuring LSP (Label Switched Path, Label Switched Path), and the network management of a domain in the existing project cannot know the fiber connection port information in the adjacent domain connected to it, so it cannot support cross-domain service configuration of SPTN equipment

Embodiment 1

[0049] See figure 1 As shown, the embodiment of the present invention provides a method for cross-domain service configuration of SPTN equipment, which includes the following steps:

[0050] A. Obtain all physical topology information of the domain according to the requirements issued by the upper domain controller to collect the topology information of the domain; according to the path finding conditions issued by the upper domain controller to query the reachable path between the boundary network elements in the domain, Obtain one or more optional paths in this domain that meet the pathfinding conditions, and use them as intra-domain routes, and assign an available label to each network element in the path; according to the query issued by the upper domain controller, the boundary network element of the domain is assigned an incoming label To obtain the inbound tags available for the boundary network element;

[0051] B. Combine into a complete cross-domain LSP (Label Switched Pa...

Embodiment 2

[0068] On the basis of embodiment 1, step B specifically includes the following steps:

[0069] The configuration of cross-domain LSP requires clear intra-domain routing and inter-domain routing. Intra-domain routing refers to the routing between the NNI (Network to Network Interface) of border network elements, and the inter-domain routing refers to the route from the border network element to the neighbor Routes of external network elements.

[0070] There may be multiple reachable routes within a domain, and the specific one to be selected is specified by the user. Intra-domain reachable paths refer to routes between NNI interfaces of border network elements, but a complete cross-domain LSP includes not only intra-domain routing, but also inter-domain routing.

[0071] Inter-domain routing includes cross-domain ports and cross-domain labels. Cross-domain ports are the outbound ports of boundary network elements within the domain, which determine the port from which data packets s...

Embodiment 3

[0081] On the basis of embodiment 1, step C also includes the following steps:

[0082] The available VCID of the boundary network element in the local domain is one or more range intervals, which are used by the upper domain controller to negotiate the available VCID of the boundary network element in the foreign domain, and find common VCID ranges between the boundary network elements in the local domain and the foreign domain The available VCID is used as a condition for configuring the virtual circuit.

[0083] Idle VCIDs are used for inter-domain VC circuit intercommunication. The query method is similar to that of querying available idle tags in step A of Embodiment 1, and the method of determining the idle state in descending order of ID value is also adopted.

[0084] The difference from the query tag is that the available VCIDs need to get all the collections at one time. Since the number of available IDs is generally large, it is impossible to list them all, so the results ...

Abstract

The invention discloses a method and system for configuring cross-domain services on SPTN equipment, and relates to the management field of telecommunication transmission networks. The method includes the following steps: collecting local domain topology information, querying the reachable paths between border network elements in the local domain, and obtaining available incoming labels of border network elements; combining cross-domain label switching path LSP routes; taking cross-domain LSP routes as input conditions, Configure the cross-domain LSP service of SPTN equipment; query the available idle VCID of the border network element in the local domain; use the successfully configured LSP service as the service layer, use the idle VCID available in the border network element of the local domain, and configure the cross-domain virtual circuit and virtual circuit of the SPTN equipment ELine business. The invention can support cross-domain service configuration of SPTN equipment.

Description

Technical field [0001] The invention relates to the management field of a telecommunication transmission network, in particular to a method and system for cross-domain service configuration of SPTN equipment. Background technique [0002] With the rapid development of telecommunications services, the rapid increase in the number of users and the rapid increase in service quality requirements, as well as the continuous enrichment of application types, the network architecture has become increasingly complex, the bearer function has continued to expand, and the corresponding management and control capabilities have gradually weakened. The current network architecture Has shown some drawbacks. Under the trend of hardware standardization, equipment softwareization, and telecommunications network ITization, SDN (Software Defined Network) has become the focus of attention of emerging Internet operators, traditional telecommunications operators, and equipment suppliers. With the popula...
