Detailed Description
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention. In addition, the technical features of the embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
Embodiment one:
in order to optimize the service configuration flow and shorten the service configuration and issuing time, the traditional mode at present is to configure the end-to-end dedicated line service after the installation of the access equipment at two ends, but because the installation of the access equipment is time-consuming, network resources are required to be ensured not to be preempted by other dedicated line services by a manual mode. When the access equipment is deployed, field engineering personnel electrify the equipment and connect the fiber, and the equipment needs to be repeatedly communicated with a network operation center engineer to confirm whether the equipment is correctly installed and uploaded to a network management system. When the special line service is configured, the network engineer manually configures the service, the basic parameters are more, the time consumption is long, the error rate is high, and the requirements on the skills of the engineer are high.
The first embodiment provides a method for automatically extending network management service, which realizes the full-process automatic management of service opening, performs end-to-end service configuration and issuing through virtual resources in the network management, automatically extends the service to the access equipment after the access equipment is on line, and realizes the plug-and-play of the access equipment. The method comprises the following steps:
s101: the network manager creates virtual resources corresponding to the non-access equipment according to the service configuration parameters, and creates the service to the virtual resources in advance to form the end-to-end service.
Under the condition that the source and destination access devices are not on line, the source and destination access devices are virtual in the network management, and when an operator upper layer system performs service configuration operation through an interface or a network management maintainer performs service configuration operation, the network management automatically creates virtual resources corresponding to the source and destination access devices according to service configuration parameters, and source-to-destination service is formed in the network management. If the source/destination access equipment is on line, the other access equipment is virtual in the network manager, the network manager automatically creates virtual resources corresponding to the access equipment which is not on line according to the service configuration parameters, and source/destination service is formed in the network manager. The service delivery can be directly carried out on the access equipment which is already provided or is already online in the network management.
And under the condition that the access equipment is not on line, the convergence equipment and the backbone equipment reserve bandwidths for the access equipment, wherein the bandwidths are 100M, 200M, 500M or 1G and the like, the bandwidth size is determined according to the service type, for example, if the service type is GE, the convergence equipment and the backbone equipment reserve bandwidths of 1.25G, and when the access equipment is on line to open the service, the bandwidth resources are prevented from being occupied by other services. After the access equipment is on line, the network management can also continue to build the service according to the common scene, namely, the complete service is built in real time, and virtual resources are not required to be built. A complete service path is formed by access-convergence-backbone-convergence-access.
S102: after the access equipment is online, the access equipment is in butt joint with the convergence equipment, the convergence equipment automatically discovers the access equipment in butt joint with the access equipment and reports the access equipment to a network manager, the network manager automatically creates an access network element according to the reported information of the convergence equipment, and deletes the virtual connection fiber between the virtual network element in the virtual resource and the convergence network element corresponding to the convergence equipment, and creates the connection fiber between the access network element and the convergence network element.
After the entity access equipment is connected to the convergence equipment through the connection fiber, the convergence equipment reports to the network manager, and the network manager creates objects corresponding to the access equipment, such as access network elements, access single disks and access connection fiber. On the premise of virtual resources, for example, a port A on an original virtual network element is connected to a port B on a converging network element through a virtual connection fiber, after an access device is connected to the converging device after being connected to the line, a network manager creates the access network element, deletes the virtual connection fiber between the virtual network element and the converging network element, continuously creates the connection fiber from a port C on the access network element to a port B on the converging network element, and automatically migrates to a port C on the access network element through a service on the port A of the virtual network element so as to realize automatic extension of network management service.
S103: and the network manager migrates the service on the virtual network element in the virtual resource to the access network element corresponding to the access equipment, and issues the service data on the access network element completing service migration to the access equipment.
When the virtual connection fiber between all the virtual network elements and the convergence network elements on one end-to-end service is replaced, the network manager migrates the service data of each layer on the virtual network elements of the end-to-end service to the access network element created by the network manager in the step S102, and completes the network management service migration.
After the access device is on line, one of source end service extension, destination end service extension or double-end service extension can be performed.
In the first embodiment, the above problems are solved by creating a service by using a virtual resource and an automatic extension mechanism, and before the installation and measurement of the access device are completed, the service is created in advance on the virtual resource to form an end-to-end service, so that bandwidths of the convergence device and the backbone device are reserved for the access device service, and the availability of the resources of the dedicated line service is ensured. After the access equipment is on line, the network manager automatically extends the service to the access equipment, so that quick service configuration is realized, the special line service is accelerated to be on line, and the user experience is improved.
In order to create a virtual resource corresponding to an access device, in combination with the embodiment of the present invention, there is also a preferred implementation scheme, specifically, as shown in fig. 2, the network manager creates a virtual resource corresponding to a device without an access device according to a service configuration parameter, the network manager creates a service in advance on the virtual resource to form an end-to-end service, and simultaneously, performs service delivery on an access device existing in the network manager, and the specific method includes the following steps:
S201: and taking the virtual network element which does not have the corresponding access equipment and the access network element which has the corresponding access equipment as source and destination network elements for seeking paths according to the service configuration parameters and the virtual resources.
In the first embodiment, the service configuration parameters originate from a north interface (upper layer network management of the operator) or a network management interface, and the main parameters are shown in table one.
Table one:
according to the service configuration parameters, the network manager creates one or more of an access device virtual network element, a virtual single disk, a virtual port and a virtual connection fiber.
When the source network element or the sink network element in the service configuration parameters is the convergence device, analyzing whether a virtual network element needs to be created or not: when the aggregation network element port corresponding to the aggregation device does not have the fiber connection in the network management, a virtual network element needs to be created. The virtual network element does not need to be created every time the service is configured, and a certain port of the aggregation network element needs to be created when the service is configured for the first time and then the port is not needed to be created when the service is configured for the second time. One network side port may configure a plurality of services.
According to the service scene of the service configuration parameter, a matched virtual single disk is created, and the matching rule is shown in a table II:
and (II) table:
| Business scenario | Virtual single disk |
| EoO | Three-hybrid circuit board and Ethernet branch board |
| EOS | Three-mixing circuit board and EOS branch board |
| SDH | Three-mixing circuit board and SDH branch board |
| OTN | Three-mixing circuit board and OTN branch circuit board |
And creating a user side virtual port according to the service scene, the service type and the service bandwidth of the service configuration parameters, and creating a network side virtual port which is in butt joint with the converging network element according to the port of the converging network element.
After the virtual port of the network side is created, the network manager automatically creates a virtual connection fiber between the virtual port and the corresponding convergent network element.
And according to the service configuration parameters, the network manager performs end-to-end service routing, creation and issuing. The route searching, creation and issuing are general flows of network management service configuration, but are realized by combining virtual network elements and service configuration parameters.
And according to the source network element and the sink network element of the service configuration parameters and the virtual resource created in the step S201, the source and sink access equipment is used as a source and sink network element for seeking a path (when the source end and the sink access equipment are not provided, the source network element and the sink network element are both virtual network elements, otherwise, one end is the virtual network element).
S202: and acquiring the idle user side ports of the virtual network element in the virtual resource according to the service configuration parameters, and taking the idle user side ports of the virtual network element and the user side ports of the access equipment as source and destination ports of the service.
In the first embodiment, according to the "service scenario", "service type" and "service bandwidth" of the service configuration parameters, the user side ports available on the virtual network element (the access device that is not provided) in the virtual resource are obtained, and the user side ports that are idle for the virtual network element and the user side ports that are provided with the access device are used as the source/sink ports of the service.
There are three specific scenarios:
the source access equipment is not provided, the sink access equipment is provided, the user side port of the virtual network element which corresponds to the source access equipment in the virtual resource is obtained according to the service configuration parameters, the user side port of the virtual network element which is idle is used as the source port of the service, and the user side port of the sink access equipment is used as the sink port of the service.
The source access equipment is not provided with the sink access equipment, the user side port of the virtual network element which corresponds to the sink access equipment in the virtual resource is obtained according to the service configuration parameters, the user side port of the virtual network element which is idle is used as the sink port of the service, and the user side port of the source access equipment is used as the source port of the service.
The source access equipment does not comprise the sink access equipment, the source access equipment and the sink access equipment in the virtual resources are respectively obtained according to service configuration parameters, the user side ports of the virtual network element which correspond to the source access equipment and the sink access equipment are idle, and the user side ports of the virtual network element which are idle are used as the source ports and the sink ports of the service.
S203: and taking a virtual network element network side port in the virtual resource as an intermediate port, and carrying out path finding according to the service configuration parameters.
In the first embodiment, the network side port of the virtual network element is taken as an intermediate port, and is a necessary port for routing. And carrying out corresponding-level path searching according to the service scene of the service configuration parameters. The way searching is carried out in specific business layers under each business scene. For example, the service scene is an OTN, and the routing is only performed on an ODUk layer in the OTN layer; and when the service scene is EOS, the path is found in the ODUk layer, and then the VC layer is carried out for path finding. The "business scenario" of the business configuration parameters is shown in table three.
Table three:
| business scenario | Virtual single disk |
| EoO | ODUk and L2VPN routing |
| EOS | ODUk and VC way finding |
| SDH | ODUk and VC way finding |
| OTN | ODUk route finding |
S204: and carrying out service creation and issuing equipment according to the path finding result, wherein service data on the virtual network element is not issued by the equipment.
In the first embodiment, the virtual network element is a network element (no physical device exists) which is not deployed yet, and the virtual network element does not need to be issued to the device in the network management, and no corresponding device can issue data. The business scenario determines the business hierarchy to be configured, and the business hierarchy in the first embodiment belongs to the hierarchical relationship of the industry standard. For example, when the service scene is OTN, the service hierarchy is from bottom to top: OCH, OTUk, ODUk and Client. The service hierarchical relationship in the service scene is shown in table four (the service single disk is directly connected between the access device and the convergence device, and the service single disk does not pass through the wave combining disk, the wave dividing disk and the amplifying disk, and does not have an OMS layer and an OTS layer).
Table four:
| business scenario | Business hierarchy |
| EoO | OCH、OTUk、ODUk、L2VPN |
| EOS | OCH、OTUk、ODUk、VC、VCG、L2VPN |
| SDH | OCH、OTUk、ODUk、VC |
| OTN | OCH、OTUk、ODUk、Client |
