Description
Description
Technical Field The present invention relates to a passive optical network technology, and particularly to an OLT network element monitoring device, monitoring system and management method.
Background PON is a typical passive optical network, and means that any electronic device and electronic power supply are not contained (in an optical distribution network (ODN)). The ODN is composed of passive devices such as optical splitters, and does not require valuable active electronic devices. A passive optical network comprises an optical line terminal (OLT) installed on a central control station and a batch of supporting optical network units (ONUs) installed at user sites. Deregulation means that a network management unit cannot manage network element equipment normally. For example, a network element in a deregulation state turns grey on a management interface or the network element cannot be logged in. The network management unit establishes socket connection with a gateway network element. The network management unit periodically monitors whether the socket connection is normal. If there is no response after contact for three times (36 seconds each time), the socket is disconnected and an alarm is reported. The network management unit conducts DCN monitoring between the gateway network element and a non-gateway network element. If there is no response for three times, the equipment is set to a deregulation state. Once the network element equipment is in the deregulation state, manual maintenance is usually arranged to realize the communication of the network element equipment as soon as possible. High maintenance cost is often caused.
Summary In view of the defects of the prior art, the present invention provides an OLT network element monitoring device, monitoring system and management method. Specifically:

Description
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and fully described below in combination with the drawings in the embodiments of the present invention. Apparently, the described embodiments are merely part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those ordinary skilled in the art without contributing creative labor will belong to the protection scope of the present invention. At present, there are many reasons for deregulation of network element devices. For example, reason 1: the software of the network element devices fails. For example, the software has many services coming out and cannot respond to monitoring messages of network management. Reason 2: the hardware of the network element devices fails, and cannot respond to the monitoring messages of network management. Reason 3: the network fails, and network management cannot transmit the packets of a gateway network element. Reason 4: DCN channels have small bandwidth and large network construction, leading to reduction in routing calculation. When the network changes, routing information is continuously broadcast in the whole DCN network, leading to too long convergence time of a routing table, network congestion and no reply to the monitoring packets of a non-gateway network element by network management. In the above failure reasons, only the reason 2 needs artificial site processing, and the other four reasons can be solved in a remote mode. Thus, the applicant conducts beneficial research and exploration, and proposes a method and device for improving deregulation performance of network management for OLT network element devices. The method can greatly increase the online rate of the OLT network element devices, and can avoid frequent online and offline operation of the OLT network element devices under the condition that the OLT management network is unstable to alleviate the burden of a network management serving end. The technical solution explained below is generated under this background. As shown in Fig. 1, in one aspect, the present application provides an OLT network element monitoring device, comprising: a monitoring unit, for monitoring states of OLT network element devices in a current network environment, and forming network element data information matched with the OLT network element devices according to a communication state and/or a
Description
monitoring result in the current network environment, wherein the OLT network element devices comprise OLT network element devices added to a current network and/or OLT network element devices in an offline state. Schematically, the monitoring unit can periodically scan the state information of the OLT network element devices in the current network environment. For example, if the monitoring unit finds that the online state of the OLT network element devices is changed, the monitoring unit generates an interruption signal and sends the state of the OLT network element devices to a protection state machine. It can also be understood that the OLT network element devices are changed from an online state to an offline state. After the monitoring unit monitors the change, the monitoring unit forms an interruption signal for the OLT network element devices in the offline state and sends the interruption signal to the protection state machine. The monitoring unit can periodically scan the state information of the OLT network element devices in the current network environment. For example, if the monitoring unit finds an added OLT network element device, the monitoring unit generates an indication signal and sends the configuration information of the added OLT network element device to the protection state machine. Further, the monitoring unit can monitor whether an upper optical port of the OLT network element device has no light alarm to recognize the state of the device and notify the protection state machine. For example, when the upper optical port of the OLT network element device has no light alarm, it indicates that the OLT network element device corresponding to the no light alarm is in the offline state; otherwise, it indicates that the OLT network element device is in the online state. The protection state machine, for receiving the network element data information matched with the OLT network element devices and updating the network element data information to a network element information database. Schematically: The protection state machine connects the device monitoring unit and a network interface and performs calculation according to the received related information of the online state of the network element to judge whether the device is deregulated or restored to the online state. When finding device deregulation, the state machine changes the IP address of the OLT network element monitoring device through the network interface, changes the IP address of the OLT network element monitoring device to the IP address of the OLT network element device in the offline state, and responds to a service request of a network management serving end instead of the
Description
OLT network element device in the offline state. After finding that the OLT network element device in the offline state is restored to the online state, the protection state machine releases the IP address of the OLT network element device in the offline state actively and restores the IP address of the OLT network element monitoring device to the original address of the OLT network element monitoring device. A network element information database, for storing the network element information data of the network element data information matched with the OLT network element devices. The network element information data at least comprises network configuration information such as IP address and network element name, and can also comprise state information such as configuration including network element port and crossing, alarm and performance. When the monitoring unit recognizes that a new OLT network element device is online or the configuration state of the online device changes, the related information is updated to the database for storage. When finding device deregulation, the state machine reads the configuration state information saved in the database and makes a reply when replacing the OLT network element device in the offline state for responding. An SNMP unit, for outputting the network element data information under a request of a query message in a state of receiving an SNMP query packet. Preferably, the above OLT network element monitoring device further comprises: a network interface, connected with the monitoring unit and used for monitoring an optical signal of an uplink service port of an OLT network element to monitor the states of the OLT network element devices and to form the monitoring result output, or used for connecting an operating device. Specifically, the network interface monitors an optical signal of an uplink service port of an OLT network element to monitor the states of the OLT network element devices, and forms no light alarm output in a state of not acquiring the optical signal. As a further preferred implementation solution, the above OLT network element monitoring device also comprises an alarm unit. In a state of monitoring the OLT network element devices in a continuous offline state, the monitoring unit reports an alarm to a central apparatus room and triggers the dispatching of workers to a site to treat a troubleshooting process. For example, if the OLT network element devices in the offline state are still in the offline state after predetermined time of monitoring, a corresponding alarm needs to be reported. The predetermined time can be 30 seconds, 1 minute, 2 minutes, etc.
Description
As a further preferred implementation solution, in the above OLT network element monitoring device, the operating device is at least one of a monitor, a keyboard, a mouse, a tracking plate and a touch plate. It should be noted that the OLT network element monitoring device can be configured with a plurality of network cards and a plurality of IPs. The device can simultaneously simulate the offline situation of a plurality of OLT network element devices. Embodiment 2 As shown in Fig. 2, the present application further provides an OLT network element monitoring system, comprising: OLT network element devices; An OLT network element monitoring device, connected with the OLT network element devices and used for acquiring a state and basic parameters of the OLT network element devices in a current network environment, forming monitoring data according to the states of the OLT network element devices and forming a basic database according to the basic parameters; Schematically, when the OLT network element monitoring device is connected to a network environment, the OLT network element monitoring device can automatically acquire an IP address through DHCP or obtain an idle IP address by a method manually set by a user. After the OLT network element monitoring device acquires the IP address, the OLT network element monitoring device realizes communication connection with the OLT network element devices and the network management serving end. The OLT network element monitoring device periodically scans the operating state of a plurality of OLT network element devices in the current network environment. Further, the OLT network element monitoring device judges the states of the OLT network element devices by a method of timing PING packets or a method of monitoring the optical fiber signals at the upper interface of the OLT network element devices. A network management serving end, connected with the OLT network element monitoring device for receiving the monitoring data under the effect of a query request. When the OLT network element devices are in an online state, the network management serving end sends SNMP GET/SET packets to periodically query and update common configurations and state information of the OLT network element devices, such as configuration information of network element, port and service, and
Description
state information of alarm and performance, and stores the information locally. After monitoring that the OLT network element devices are offline, for example, PING packets fail or the optical fiber of the upper interface is dull, the OLT network element monitoring device changes the IP of the OLT network element monitoring device to the IP address of the OLT network element devices in the offline state, and receives a service request sent by the network management serving end to the offline OLT network element instead of the OLT network element device in the offline state. Meanwhile, the OLT network element monitoring device outputs a feedback value to form the OLT network element in an online state. Further, the query of the offline OLT network element devices by the network management serving end can comprise network configuration, such as ifconfig, ping, netstat, etc., and can also comprise the common operation on the OLT network element device by the network management serving end, such as querying network element ports, service configuration, and alarm and performance states. Schematically, after the OLT network element device receives a network management request, the OLT network element device firstly compares and searches the network element data information queried and stored, forms return packets from the search results, feeds back to the network management serving end and provides historical data when the OLT network element device is online. When the OLT network element monitoring device simulates an offline OLT network element device, the OLT network element monitoring device needs to periodically monitor the states of the OLT network element device, for example, to periodically change the IP of the OLT network element monitoring device back to the original IP, and monitor whether the IP of the offline OLT network element device in the existing management network responds, or whether the no light alarm of the upper interface of the offline OLT network element device is eliminated. Once monitoring that the offline OLT network element device is restored to be online, the offline OLT network element device is not simulated, the IP address of the OLT network element monitoring device is changed back to the original configuration, and the management for the real OLT network element device by the network management serving end is restored. In the process of simulating the offline OLT network element device, if the offline OLT network element device is not restored to be online, the OLT network element monitoring device can report an alarm to the central apparatus room and trigger the dispatching of workers to a site to treat a troubleshooting process.
Description
In the method and device for improving deregulation performance of network management for OLT network element devices proposed by the present invention, the device can be configured with a plurality of network cards and a plurality of IPs. The device can simultaneously simulate the offline situation of a plurality of OLT network element devices. A specific implementation mode is listed. In an OLT network element monitoring system, the OLT network element monitoring device is connected to a network environment, which can find each OLT network element device in the network environment and can read the configuration information in the OLT network element devices through network commands and snmp commands. In addition, the OLT network element monitoring device can monitor whether the states of the OLT network element devices are normal and maintain an information database related to the OLT network element devices in the network and the configuration information of the OLT network element devices. The network environment can also be extended by a switch or a router. The switch is a device that connects two or more segments of the same network using a common protocol (e.g., Ethernet or token ring), and the router can extend a plurality of devices using different layer 2 network protocols. In this embodiment illustrated, the switch comprises a plurality of communication ports for sending and receiving data, and maintains forwarding tables associated with each port. Each forwarding table contain the addresses (for example, IP addresses and MAC addresses) of other OLT network element devices connected to the port. The network management serving end is used for centrally managing OLT network element devices. The network management serving end comprises at least: service terminals, and the service terminals comprise: a communicator, a memory and a processor. Wherein the communicator is used for communicative connection with at least one of the OLT network element devices; The memory is used for storing computer programs; The processor is used for executing the computer programs stored by the memory so that the service terminal executes a network element device management function; and The OLT network element device connected with the network management serving end is called "a gateway network element". The gateway network element is
Description
directly connected with the service terminal, and the communication mode can be an in-band communication mode or an out-of-band communication mode. The in-band communication mode uses a network management channel based on a communication channel byte in a service frame as a physical path. The out-of-band communication mode uses an external data communication network as a physical path. In this embodiment illustrated, the out-of-band communication mode is adopted. In general, the network management serving end is communicated with the network element device in accordance with the Simple Network Management Protocol (SNMP). The network management serving end can acquire information from the network element device through SNMP packets. A plurality of OLT network element devices are connected to the network environment by the switch, and more remote OLT network element devices can be connected to the network through Internet. The network environment is arranged to allow any OLT network element device to exchange data with the OLT network element discovering/monitoring device in the network environment. Even more specific bridges can be connected to any number of computing devices or other network element devices, and the interactive network environment can comprise other types of network devices (such as routers, gateways, switches, network hubs and similar network devices). In the actual use process, the OLT network element device in the offline state is not monitored by the network management serving end. In the feedback data of a gateway serving end, the OLT network element device in the offline state is still in the "online" state, that is, the SOCKET connection state between the gateway serving end and the gateway network element is normal. The gateway serving end may not frequently send connection monitoring commands. The OLT network element device in the offline state can only process the tasks before a response request is sent. After the accumulated network tasks are processed, the response request is fed back. It can be understood that the OLT network element device processes only the received tasks and receives externally sent task requests after the tasks are processed. On the one hand, the own offline state can be "self-healed". On the other hand, the OLT network element device only processes important tasks or events, ignores interrogative requests, and centrally processes important events for limited resources. Embodiment 3 As shown in Fig. 3, the present invention provides a management method of
Description
OLT network element devices, which needs to build a network environment before the management method of OLT network element devices is executed. The management method of OLT network element devices is executed in the above network environment: an executing unit of the management method may be an OLT network element monitoring device, comprising: Step S110, forming an abnormality detecting signal in a state of not receiving a query response, and reading sign information matched with the abnormality detecting signal. Specifically: When no corresponding response packet is received by the query response, it is judged that the OLT network element device corresponding to the response packet is in an offline state. At this moment, the sign information of the OLT network element device in the offline state is read, and the sign information includes, but is not limited to the IP address information. Schematically, a method of timing PING packets or a method of monitoring the optical fiber signals at the upper interface of the OLT network element devices can be used to judge whether the OLT network element devices are online. When the OLT network element devices are monitored in an online state, SNMP GET/SET packets can be sent to periodically query and update common configurations and state information of the OLT network element devices, such as configuration information of network element, port and service, and state information of alarm and performance, and stores the information locally. Step S120, forming an indexing signal according to the sign information, writing in the indexing signal and forming request feedback information output matched with a service request. Specifically, the OLT network element monitoring device writes the IP address of the OLT network element device in the offline state into the own device. At this moment, the IP address information of the OLT network element monitoring device is the IP address information of the OLT network element device in the offline state. Meanwhile, the OLT network element monitoring device receives the service request (the service request sent by the gateway serving end) and returns request feedback data matched with the service request to a network server. In some embodiments, when the OLT network element devices are monitored in an online state, the gateway serving end can also send SNMP GET/SET packets to periodically query and update common configurations and state information of the OLT network element devices, such as configuration information of network element,
Description
port and service, and state information of alarm and performance, and stores the information locally. In some embodiments, in a state that PING packets fail or the optical fiber of the upper interface is dull, it is judged that the OLT network element devices are in the offline state, and the OLT network element monitoring device temporarily changes the IP of the OLT network element monitoring device to the IP address of the OLT network element devices in the offline state and receives the service request instead of the OLT network element device. At this moment, the OLT network element device in the offline state is not monitored by the network management serving end. In the feedback data of the gateway serving end, the OLT network element device in the offline state is still in the "online" state, that is, the SOCKET connection state between the gateway serving end and the gateway network element is normal. The gateway serving end may not frequently send connection monitoring commands. The OLT network element device in the offline state can only process the tasks before a response request is sent. After the accumulated network tasks are processed, the response request is fed back. It can be understood that the OLT network element device processes only the received tasks and receives externally sent task requests after the tasks are processed. On the one hand, the own offline state can be "self-healed". On the other hand, the OLT network element device only processes important tasks or events, ignores interrogative requests, and centrally processes important events for limited resources. Specifically, the OLT network element monitoring unit finds the offline OLT network element device in the management network environment. The protection state machine firstly reads the IP address of the offline OLT network element device and assigns the IP address of the offline OLT network element device to the IP address of the OLT monitoring unit. The OLT monitoring unit receives the service request matched with the assigned IP address, forms request feedback information as a responder according to the service request and sends the information to a sender of the service request. The offline OLT network element device always processes other request tasks except the service request. As a further preferred implementation solution, the management method of OLT network element devices further comprises: step S130, writing in initial sign information in a state of writing in predetermined time matched with the duration of the indexing signal; forming a
Description
detection sign matched with the abnormality detecting signal, and forming a detection result according to the detection sign; step S140, outputting the detection result under the effect of the initial sign information. Specifically, when the initial address is written into the OLT monitoring unit, the OLT monitoring unit can receive the SNMP query packets sent by the gateway serving end. When the OLT monitoring unit receives the SNMP query packets, similar information including "normal data transmission" signal is formed according to the IP address of the OLT device in the offline state to respond to the SNMP query packets sent by the network management serving end. In short, the OLT monitoring unit is switched between a monitoring function and the replacement of the offline OLT network element device, and the preset time is matched with the frequency at which the OLT monitoring unit responds to the SNMP query messages. In the switching process of the OLT monitoring unit, the gateway serving end is prevented from frequently sending query commands. If the current OLT network element device is operated at full load, the network of the terminal corresponding to the OLT network element device is disconnected, and the entire network environment is in an unsteady state. The method of the present application can avoid frequent online and offline operation of the OLT network element devices and alleviate the burden of a gateway system. Step S150, releasing the sign information by the OLT unit in a state of acquiring a response matched with the sign information. In other words, the OLT network element device in the offline state has been restored to be online. At this moment, the OLT monitoring unit does not need to change the own operating mode and the OLT monitoring unit is always operated in a monitoring mode. Steps S11-S140 are executed circularly in a state of not acquiring a response matched with the sign information. As a further preferred implementation solution, the management method of OLT network element devices further comprises, before reading a sign signal matched with the abnormality detecting signal in a state of acquiring the abnormality detecting signal: step S109, polling the OLT network element devices in the current network environment to acquire the sign information of each OLT network element device. Specifically:
Description
step S1091, polling the online OLT network element devices in the current network environment; step S1092, forming device database information according to the existing registration information in a state that all online OLT network element devices are registered in the current network environment; step S1093, acquiring the sign information of unregistered OLT network element devices in a state that online OLT network element devices are not registered in the current network environment, and forming database information according to the sign information of the unregistered OLT network element devices in combination with the sign information of the registered OLT network element devices.
