Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
The first embodiment is as follows:
in order to optimize a service configuration process and shorten service configuration and issuing time, the conventional method is to configure an end-to-end private line service after completing the installation of two-end access devices, but because the installation of the access devices is time-consuming, network resources need to be ensured not to be occupied by other private line services in a manual mode. When deploying the access device, the field engineer powers on the device, connects the device with the optical fiber, and needs to communicate with the network operation center engineer repeatedly to confirm whether the device is correctly installed and upload the device to the network management system. When configuring the private line service, a network engineer manually configures the service, so that the method has the advantages of multiple basic parameters, long time consumption, high error rate and high requirement on the skill of the engineer.
The embodiment provides a method for automatically extending a network management service, which implements full-process automatic management of service activation, performs end-to-end service configuration and issuing through virtual resources in a network manager, automatically extends the service to an access device after the access device is online, and implements plug and play of the access device. The method comprises the following steps:
s101: the network management creates a virtual resource corresponding to the non-access equipment according to the service configuration parameters, and the network management creates a service in advance on the virtual resource to form an end-to-end service.
When the upper system of the operator performs service configuration operation through an interface or when the network management maintenance personnel performs service configuration operation, the network management automatically creates virtual resources corresponding to the source and sink access equipment according to the service configuration parameters, and forms source-to-sink service in the network management. If the source host has one end of the access device on line and the other end of the access device is virtual in the network management, the network management automatically creates the virtual resource corresponding to the access device which is not on line according to the service configuration parameters, and forms the service from the source end to the host end in the network management. The access device which is equipped or on-line in the network management can directly send the service.
Under the condition that the access device is not on line, bandwidth is reserved for the access device on the convergence device and the backbone device, the bandwidth is 100M, 200M, 500M or 1G, and the like, the bandwidth is determined according to the service type, for example, if the service type is GE, the bandwidth is reserved for the convergence device and the backbone device by 1.25G, and when the access device is on line to open the service, the bandwidth resources are prevented from being occupied by other services. After the access device is on line, the network management can continue to build services according to the common scene, that is, complete services can be built in real time without creating virtual resources. A complete service path is formed by access-convergence-backbone-convergence-access.
S102: the access equipment is connected with the convergence equipment after being on line, the convergence equipment automatically finds the access equipment connected with the convergence equipment and reports the access equipment to the network manager, the network manager automatically creates an access network element according to the reported information of the convergence equipment, deletes the virtual connecting fiber between the virtual network element in the virtual resource and the convergence network element corresponding to the convergence equipment, and creates the connecting fiber between the access network element and the convergence network element.
After the entity access device is connected to the convergence device through the connection fiber, the convergence device reports to the network manager, and the network manager then creates an object corresponding to the access device, such as an access network element, an access single disc and an 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 convergence network element through a virtual connection fiber, after an access device is connected to a line and then is in butt joint with the convergence device, a network manager creates an access network element, deletes the virtual connection fiber between the virtual network element and the convergence network element, continues to create a connection fiber from a port C on the access network element to the port B of the convergence network element, and automatically migrates a service on the port a of the virtual network element to the port C on the access network element, so as to realize automatic extension of network management services.
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 after completing the service migration to the access equipment.
When all the virtual fibers between the virtual network elements and the convergence network element in the end-to-end service are replaced, the network manager migrates the service data of each layer in the virtual network element of the end-to-end service to the access network element created by the network manager in step S102, thereby completing the migration of the network management service.
After the access device is on-line, one of source service extension, sink service extension or double-end service extension can be performed.
In the first embodiment, the above problems are solved by creating a service through a virtual resource and an automatic extension mechanism, before the access device is installed and debugged, the service is created in advance to the virtual resource to form an end-to-end service, and bandwidths of convergence devices and backbone devices are reserved for the service of the access device, so that the resource availability of a private line service is ensured. After the access device is on line, the network manager automatically extends the service to the access device, thereby realizing rapid service configuration, accelerating the on-line of the special line service and improving the user experience.
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, and creates a service in advance on the virtual resource to form an end-to-end service, and meanwhile, issues a service to the access device already in the network manager, where the specific method includes the following steps:
s201: and according to the service configuration parameters and the virtual resources, taking the virtual network element without the access equipment and the access network element with the access equipment as the source and sink network elements for routing.
In this embodiment, the service configuration parameter is derived from a northbound interface (upper layer network management of an operator) or a network management interface, and its main parameter is shown in table one.
Table one:
Figure BDA0003212719750000081
Figure BDA0003212719750000091
and according to the service configuration parameters, the network manager creates one or more of a virtual network element, a virtual single disk, a virtual port and a virtual fiber of the access equipment.
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: when the port of the convergence network element corresponding to the convergence device does not have a fiber connection in the network management, a virtual network element needs to be created. The virtual network element is not required to be created during each service configuration, a certain port of the convergence network element is required to be created during the first service configuration, and is not required to be created during the subsequent service configuration by using the port. A network-side port may be configured with multiple services.
Creating a matched virtual single disk according to the 'service scene' of the service configuration parameters, wherein the matching rule is shown in a table two:
table two:
business scenario Virtual single disk
EoO Three-hybrid line board and Ethernet branch board
EOS Three-hybrid line board and EOS branch board
SDH Three-hybrid circuit board and SDH branch board
OTN Three-hybrid circuit board and OTN branch 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 butted with the user side virtual port according to the port of the convergence network element.
After the network side virtual port is created, the network manager automatically creates a virtual fiber connection between the virtual port and the corresponding convergence network element.
According to the service configuration parameters, the network management carries out end-to-end service routing, creating and issuing. The path finding, creating and issuing are general flows of network management service configuration, but need to be realized by combining virtual network elements and service configuration parameters.
According to the service configuration parameters, the source network element and the sink network element, and the virtual resource created in step S201, the source access device is used as a source sink network element for routing (when neither the source access device nor the sink access device is available, both the source network element and the sink network element are virtual network elements, otherwise, one end is a virtual network element).
S202: and acquiring an idle user side port of a virtual network element in the virtual resource according to the service configuration parameters, and taking the idle user side port of the virtual network element and the user side port with the access equipment as source and destination ports of the service.
In this embodiment, according to the "service scenario", "service type", and "service bandwidth" of the service configuration parameter, an available user-side port on a virtual network element (an access device not provided) in a virtual resource is obtained, and an idle user-side port of the virtual network element and a user-side port provided with the access device are used as source/destination ports of a service.
There are specifically three scenarios:
the source end access device is not provided with the source end access device, the sink end access device is provided with the sink end access device, the idle user side port of the virtual network element corresponding to the source end access device in the virtual resource is obtained according to the service configuration parameter, the idle user side port of the virtual network element is used as the source port of the service, and the user side port of the sink end access device is used as the sink port of the service.
The source end access device is provided with a sink end access device, the idle user side port of the virtual network element corresponding to the sink end access device in the virtual resource is obtained according to the service configuration parameter, the idle user side port of the virtual network element is used as the sink end port of the service, and the user side port of the source end access device is used as the source end port of the service.
The source end access equipment and the sink end access equipment are not provided, idle user side ports of the virtual network elements corresponding to the source end and the sink end access equipment in the virtual resources are respectively obtained according to the service configuration parameters, and the idle user side ports of the virtual network elements are used as a source port and a sink port of the service.
S203: and taking a network side port of a virtual network element in the virtual resource as an intermediate port, and performing path finding according to the service configuration parameters.
In this embodiment, a network-side port of a virtual network element is used as an intermediate port, which is a port that is necessary for routing. And carrying out corresponding level routing according to the 'service scene' of the service configuration parameter. The way finding is to perform way finding in a specific service level under each service scene. For example, the service scenario is OTN, and path finding is performed only in an ODUk layer in the OTN layer; when the service scene is EOS, the path searching is firstly carried out on an ODUk layer, and then the path searching is carried out on a VC layer. The "service scenario" of the service configuration parameter is shown in table three.
Table three:
business scenario Virtual single disk
EoO ODUk route finding and L2VPN route finding
EOS ODUk path finding and VC path finding
SDH ODUk path finding and VC path finding
OTN ODUk path finding
S204: and according to the routing result, service creation and issuing equipment is carried out, wherein the service data on the virtual network element is not issued.
In this embodiment, the virtual network element is a network element that is not yet deployed (there is no physical device), and there is no need to issue data to a device in the network management, and there is no corresponding device that can issue data. The service scenario determines a service hierarchy to be configured, and the service hierarchy in the first embodiment belongs to a hierarchical relationship of an industry standard. For example, when the service scenario is OTN, the service hierarchy is from bottom to top: OCH, OTUk, ODUk, and Client. The service hierarchical relationship in the service scenario is shown in table four (the access device and the convergence device are directly connected by a service single disk, and do not pass through a wave combination disk, a wave division disk and an amplification disk, and do 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
After the virtual end-to-end service is created, the service in the virtual resource is automatically extended to the access equipment after the access equipment is on line.
