Description

Resource synchronization method and device

TECHNICAL FIELD The present invention relates to the field of communications, and in particular, to a resource synchronization method and apparatus. BACKGROUND OF THE INVENTION Telecommunication network resource management is used to manage various physical resources, pipeline resources, channel resources, and circuit resources of operators. The NEs, racks, subracks, boards, ports, and optical network units (ONUs) of the access device belong to physical resources. Network resource management is the most important part of the telecommunication network operation and maintenance support system. The network resource management system is the basis for telecommunication network operators to carry out network maintenance, service distribution, network optimization and network planning, and various operation and maintenance activities of telecommunication network operators. All are built around network resources. When the state and information of the network physical resources change, the resource management system needs to update the telecommunication network resources in time to ensure that the network resource system feeds back the latest resource information in real time, thereby ensuring the accuracy of other operation and maintenance activity data. The NE device management system (hereinafter referred to as the network management system or network management system, or EMS for short) is a system for directly managing NE devices. As shown in Figure 1, the NMS manages connections through the southbound interface and NEs, and through the northbound interface and carriers. The upper layer management support system (OSS) is connected. When the resource status or information changes, the network management system first collects the change information of the resource through the southbound interface, and then notifies the resource system of the resource status through the northbound interface. The information is updated. According to the definition of ITU-T G.902, the Access Network (AN) is a Service Node Interface (SNI) and a User Network Interface (UNI). Consisting of a series of transport entities, the access network is an implementation system that provides the transport bearer capabilities required to transport telecommunications services. The access network generally needs to have local management tools for local management. For example, when the device is deployed, the deployment engineer uses the local deployment tool software (for example, the Local Craft Terminal (LCT) provided by the device provider. ) Software or Telnet) Initial configuration of the device to the device. The initial deployment configuration includes some basic resource configuration. The hardware resource configuration of the device mainly includes the configuration of the rack, chassis, and board of the device. When the device is faulty, the maintenance personnel need to use local management tools to log in to the device for local configuration modification. The modification of the device configuration data needs to be timely fed back to the network management system and the resource management system. Only in this way can the data accuracy of resource-based operation and maintenance activities be guaranteed. In TMF (short for Tele Management Forum, is a service for telecommunications The requirements for resource timeliness and accuracy are also addressed in the relevant standards for managing the world's organizations that provide policy recommendations and implementations. For example, in TMF 517, it is pointed out that in the NGOSS architecture, related functions such as Inventory OS and Discovery OS. The Operating System (OS for short) needs to have the function of reporting inventory update notifications. At present, access devices provided by mainstream equipment vendors are managed by Simple Network Management Protocol (SNMP). The SNMP protocol is based on the UDP protocol. Generally, the Simple Network Management Protocol (SNMP) is used. The efficiency of synchronizing or collecting resource data information is relatively low. The access network is a network facing the end user, and the number of network elements is the most typical feature of the access network element. Taking a Passive Optical Network (PON) as an example, a medium-sized passive optical network and an Optical Line Terminal (OLT) network can have more than one thousand data. In order to ensure the accuracy of the resource data, in the prior art, a periodic execution policy of resource synchronization is set on the network management system, and the network management system periodically obtains all resource configuration data from the synchronization network elements of all network elements of the entire network. To ensure the consistency of resource information between the network management system and the network element device. However, since the network element is managed by the SNMP protocol, the efficiency of such resource synchronization is relatively low, and a large amount of physical resources of the network management server and the network element device are also consumed. In response to the above problems, no effective solution has been proposed yet.

Preferred in the above In an embodiment, the network element device records the location information into the update table according to the changed time sequence, and sends the update table to the network management system, which facilitates the network management to obtain the location information of the resource update and the corresponding time information, which is easy to implement and reduces the operation. the complexity. The invention is further described in the preferred embodiments of the invention, but it is to be understood that the preferred embodiments are not intended to limit the invention. In the preferred embodiment, a method and apparatus for quickly and efficiently synchronizing resource information and status between a network management system and a network element device in an incremental manner based on an SNMP protocol are provided. In order to achieve the above object, the technical solution adopted by the present invention is as follows -

1) When the resource changes, the network element device records the specific location information of the resource instead of recording all the changes. This method is simple for the implementation of the network element device, and the network element device is at the entrance of the resource configuration operation command. The command performs preliminary analysis and records the configuration object of the configuration command, that is, the location information of the resource. Preferably, the network element device may be configured to add the resource update agent module to the location information of the resource and record the location information on the original command processing flow. Preferably, the location information representation model of the resources that need to be synchronized may be defined between the network element device and the network management system. When a resource configuration or state changes, the network element device can record the location information of the changed resource. The network management can analyze the specific location of the changed resource according to the location information, so as to synchronize the resources that need to be synchronized.

2) The network element device records all the resource configuration updates in an update table in chronological order. When the configuration update is required, the SNMP Trap is sent to the network management system, and the network management system is required to perform synchronous update of the data.

3) When the network management system finds that resource synchronization is required, the incremental difference is used for synchronization. The so-called incremental differential synchronization means that the network management system only processes the updated resource data, but does not need all resources for the network element. Process it. In the preferred embodiment, the function of each module is mainly: the network element device to be synchronized resource location storage area: in the non-volatile storage device of the network element device, the resource location information record waiting for the synchronization of the network management system is saved, the same resource The location information has only one record, and the resource location information provides an external interface for adding, deleting, and querying. Preferably, when the external module or the device calls the add interface to increase the resource location information record, the system automatically determines whether the current memory has the same record. If there is the same record, the record is not saved in the storage area; The location of the resource to be synchronized cannot be stored. Unrestricted storage of resource location information, therefore, the preferred technical implementation is that when the number of records that need to be synchronized is greater than a certain value, the record is no longer added when the recording interface is called, and the network management system can It is determined by counting the number of entries whether it is necessary to synchronize all resource data with the network element device. The NE device resource update agent module: All the resource configuration of the device is added, deleted, and modified. The local device needs to be configured in the local mode or remotely configured on the NMS. The message is forwarded to the resource update agent module, and the resource update agent module parses the resource object in the configuration command, and adds the resource object location information to the location storage area of the network element to be synchronized. After the resource update operation is initiated by the network management system, after the network element device returns to the network management device, the network management system can automatically update the resource data, and the module does not need to record the location information. In a preferred embodiment of the present invention, the resource update agent The module can configure whether all configuration changes need to be recorded. The resource update agent module can determine whether the configuration change needs to be recorded according to the IP address or protocol type initiated by the command. The NE device resource update triggering module: periodically reads the number of records in the storage location of the resource to be synchronized. When a record is found, the message is sent to the network management system through SNMP Trap. Preferably, the number of records can also be in the trap. The message is sent to the network management system as attachment information. The Trap receiving module of the network management system is responsible for receiving the Trap message sent by all the managed NE devices, and determining that the resource synchronization request trap message is forwarded to the network management system resource update processing module for resource synchronization processing. The network management system resource update processing module: After receiving the resource synchronization message, the target network element has fewer resources. The synchronization process of the network management system is shown in Figure 9, which includes the following steps:

S902: The network management system Trap receiving module parses the resource synchronization request trap message according to the network element device, parses the IP address information of the network element, and forwards the IP address information to the network management system resource update processing module to synchronize the resources;

S904: The network management system resource update processing module starts the resource synchronization thread task to perform resource synchronization of the target network element;

S906: Send an SNMP operation to the resource synchronization thread task to obtain a record of location information of all to-be-synchronized resources of the to-be-synchronized resource location storage area on the network element device.

S908: The timer is started in the resource synchronization thread task, and waits for the specified time T. The purpose of waiting for a period of time to start the synchronization operation is to allow the network management system other than the network management system to have sufficient time to obtain the same. The resource location information of the step, this method is an optional technology. If only one network management system is connected, there is no waiting time, and the following steps are directly performed. Preferably, in order to allow multiple network tubes to not acquire data at the same time, the value of T may be a random value less than 30 seconds.

S910: The resource synchronization thread task determines the number of location records of all resources that need to be synchronized obtained from the network element device. If it is greater than a specific number N, execute S912, otherwise, execute S914.

S912: The resource synchronization is performed by using the traditional resource synchronization method. After the synchronization is completed, all the resource location records to be synchronized stored on the network element are deleted, and the process ends.

S914: Obtain the next resource location A from the resource location information record, and use the SNMP operation to obtain the resource configuration data information corresponding to the resource location A. S916: Determine, according to the return result of the SNMP operation, if the read resource A is empty, but the data record corresponding to the resource A is on the network management, execute S918. If the data of the resource A on the network element is successfully obtained, the process is performed. S920.

S918: Indicates that the resource has been deleted on the network element device, and the data of the resource A is also deleted on the network management database, and the S926 is executed. S920: Determine whether the related resource information is already available on the network management device. If yes, execute S922; otherwise, execute S924 instead.

S922: Update the information of the resource A in the network management system, and then execute S926. S924: Add new resource data A is recorded in the network management system.

S926: Send an SNMP operation to the network element device, and delete the record of the resource A corresponding to the resource location storage area to be synchronized on the network element device;

S928: It is judged whether all resource records have been synchronized, if yes, the process ends, and if not, then S914 is executed, until all resource locations are synchronized. The preferred embodiments of the present invention are described in conjunction with the accompanying drawings, and the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not intended to limit the present invention; Example. Preferably, the information representation method of the resource is first defined, and the resources that the PON device needs to synchronize include the global resource (the various bandwidth template configurations of the ONU, and the virtual local area network (Virtual Local Area Network) VLAN) configuration, board resources, port resources (including PON ports), ONU resources (ONU resources include ONU version, name, line configuration under ONU, ONU service configuration, and user network interface under ONU (User Network) Interface, referred to as UNI) port configuration, etc.). It is agreed to use "Global" to indicate global resources; use "frame number-board number" to indicate board resources, for example, "2-3" means to modify the resources of board No. 3 under the No. 2 chassis; use "chassis" No. - board number - port number" indicates PON port resources; use "chassis number - board number - port number - ONU number" to indicate ONU resources, such as "2-3-4-5" means that machine 2 is required The resource configuration of the box, No. 3 PON board, No. 4 PON port, No. 5 ONU is synchronized. Secondly, define the interfaces of various SNMP operations that are exchanged between the network management system and the network element device:

1) The NE device reports the Trap message requesting the resource synchronization MIB interface; 2) The network management system obtains the MIB interface of all the resource location information to be synchronized on the NE device;

3) The network management system deletes the resource location information record MIB interface of the resource location storage area to be synchronized on the network element device;

4) The network management system synchronizes the SNMP MIB interface of the global resource, the board resource, the port resource, and the ONU resource. If the network management and the network element have defined the information management library in the traditional resource synchronization.

(Managemeng Information Base, referred to as MIB) interface, there is no need to repeat the definition here. On the NE device, the resource storage area to be synchronized is defined. The storage area is a queue. Each element in the queue is a string of data. The maximum length of the queue is 255. When the queue length is greater than 255, the record is no longer inserted. The network element device resource update proxy module is added to the network element device. All operation commands for remotely accessing the network element resource through telnet or SNMP or the local interface provided by the network element device are first received by the network element proxy, and then Send it to other modules. The specific implementation process and steps on the network element device are as follows: After the network element device receives the resource modification operation, the resource update agent module parses the resource object of the operation, and inserts the resource object into the queue of the resource storage area to be synchronized, and judges when inserted. Whether there is already the same target resource object in the queue, and if so, no action is taken. The NE device starts the resource synchronization check timer, and checks whether resources need to be synchronized every 10 minutes. If resources need to be synchronized, send a Request Resource Synchronization Trap message to the NMS server to notify it of resource synchronization. When the network element device receives the command to delete the resource record to be synchronized, the network element device deletes the corresponding resource record in the list. The network management system updates the processing flow of the Trap receiving module, and adds a step of parsing the "request resource synchronization" Trap message of the network element device in the Trap interface processing flow. After receiving the "request resource synchronization" Trap message reported by the network element, The IP address of the network element is sent to the network management system resource update processing module to perform specific network element resource synchronization processing. The network management system adds a network management system resource update processing module. In this module, a main thread is first started, which is responsible for receiving a resource synchronization request message sent by the Trap module, and managing resource synchronization requests of all network elements, and allocating threads to perform specific network elements. The synchronization of resources, at the same time create a thread pool of 100 threads, used to synchronize the resources of each network element. The network management system randomly generates a random number TimerO greater than 10 and less than 30 as the delay time parameter. The steps of resource synchronization based on the network management system described above include:

The Sl, the Trap receiving module receives the "resource synchronization request" of the network element device, parses the IP address of the Trap source network element, and sends a message to the resource update processing module for resource synchronization operation;

S2. The resource update processing module receives the resource synchronization request sent by the Trap receiving module, and starts an independent thread to perform resource synchronization of the specific target network element.

S3, sending an SNMP GetNext operation to obtain all the to-be-synchronized resource location information of the target network element device to be synchronized resource location storage area;

S4: Start a timer in the specific thread of the resource synchronization, wait for the TimerO time, and perform the following steps when the timer expires; S5: determine the number of records of the acquired resources that need to be synchronized, if greater than or equal to 255, use all the traditional The resources are synchronized to perform resource synchronization, and the process ends; otherwise, step S6 is performed;

S6: According to the resource location information data obtained in S3, according to the specific type of the resource, use the SNMP operation to obtain the corresponding resource configuration detailed information on the network element, and if the resource location information is "Global", obtain the information on the network element device. Global resource information, if it is a board, obtains specific board resource information on the NE. Compare the results of the data obtained from the network element with the data already stored on the network management:
