The PON is a typical passive optical network, which means that (in an optical distribution network) the PON does not contain any electronic devices and electronic power sources, and the ODN is composed of all passive devices such as an optical Splitter (Splitter), and does not need expensive active electronic devices. A passive optical network includes an Optical Line Terminal (OLT) mounted to a central control station and a plurality of associated Optical Network Units (ONUs) mounted to subscriber sites.
The off-management means that the network management unit cannot normally manage the network element device, for example, the network element in the off-management state on the management interface becomes grey, or the network element cannot log in, and the like. The network management and the gateway network element can establish socket connection, the network management can regularly monitor whether the socket connection is normal, if the socket connection is not responded for three times (36 seconds each time), the socket is interrupted, and an alarm is reported. DCN monitoring is carried out between the network manager and the gateway network element and between the network manager and the non-gateway network element, and if the DCN monitoring is not responded for three times, the equipment is set to be in an off-management state. Once the network element equipment is in an offline state, manual maintenance is usually scheduled to be performed in order to achieve communication of the network element equipment as soon as possible. Often resulting in high maintenance costs.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
At present, there are many reasons for the disconnection of network element equipment, for example: the first reason is that network element equipment software fails, for example, the current business of the software is more, and the network element equipment software cannot respond to the monitoring message of the network manager; the second reason is that the network element equipment hardware fails and cannot respond to the monitoring message of the network manager; the third reason is that the network fails, and the message of the network management to the gateway network element cannot be sent; and fourthly, route calculation is reduced due to excessively small bandwidth of a DCN channel and excessively large networking, and when the network changes, route information is continuously broadcast in the whole DCN network, so that the convergence time of a route table is excessively long, network congestion is generated, and the monitoring message of the non-gateway network element cannot be replied by the network manager. Among the above failure reasons, only the second reason needs manual field processing, and the other four reasons can be solved in a remote mode.
Therefore, the applicant carries out beneficial research and exploration, and provides a method and equipment for improving the offline performance of the network management of OLT network element equipment. The technical solutions described below have been created in this context.
As shown in fig. 1, in one aspect, the present application provides an OLT network element monitoring device, including:
the monitoring unit is used for monitoring the state of OLT network element equipment in the current network environment and forming network element data information matched with the OLT network element equipment according to the communication state and/or a monitoring result in the current network environment; the OLT network element equipment comprises OLT network element equipment newly added into the current network and/or OLT network element equipment in a disconnection state;
illustratively, the monitoring unit may scan status information of the OLT network element device in the current network environment at regular time, for example, when the monitoring unit finds that the online status of the OLT network element device changes, an interrupt signal is generated, and the status of the OLT network element device is sent to the protection state machine; it can also be understood that the OLT network element device changes from the online state to the offline state, and the monitoring unit monitors the change to form an interrupt signal of the OLT network element device in the offline state, and sends the interrupt signal to the protection state machine. The monitoring unit may scan status information of the OLT network element device in the current network environment at regular time, for example, when the monitoring unit finds a newly added OLT network element device, an indication signal is generated, and configuration information of the newly added OLT network element device is sent to the protection state machine.
Further, the monitoring unit may also identify the device status and notify the protection state machine by monitoring whether there is no light alarm at the upper optical connection port of the OLT network element device; for example, when there is no light alarm at the upper optical coupling port of the OLT network element device, it indicates that the OLT network element device corresponding to the no light alarm is in a disconnection state. Otherwise, the OLT network element equipment is in an online state.
The protection state machine receives the network element data information matched with the OLT network element equipment and updates the network element data information to a network element information database; in the schematic view of the above-mentioned,
the protection state machine is connected with the equipment monitoring unit and the network interface, and is used for calculating according to the received network element online state related information and judging whether the equipment is offline or online. When the equipment is found to be offline, the state machine modifies the IP address of the OLT network element monitoring equipment through the network interface, modifies the IP address of the OLT network element monitoring equipment into the IP address of the OLT network element equipment in the offline state, and replaces the OLT network element equipment in the offline state to respond to the service request of the network management server; and when the OLT network element equipment in the offline state is recovered to be online, the protection state machine can actively release the IP address of the OLT network element equipment in the offline state and recover the IP address of the OLT network element monitoring equipment to the initial address of the OLT network element monitoring equipment.
The network element information database is used for storing the network element information data of the network element data information matched with the OLT network element equipment; the network element information data at least includes network configuration information such as an IP address and a network element name, and may also include configuration such as a port and a cross of a network element, and status information such as an alarm and performance. When the monitoring unit identifies that the configuration state of new OLT network element equipment is on line or the configuration state of equipment which is on line is changed, relevant information is updated to a database for storage; when the device is found to be offline, the state machine reads the configuration state information stored in the database to respond when the state machine replaces the OLT network element device in the offline state to respond.
And the SNMP unit is used for outputting the network element data information under the request of the query message in the state of receiving the SNMP query message.
Preferably, the above OLT network element monitoring device further includes:
the network interface is connected with the monitoring unit and used for monitoring the optical signal of the uplink service port of the OLT network element so as to monitor the state of the OLT network element equipment and form the monitoring result to be output; or, to connect to an operating device.
Specifically, the network interface monitors an optical signal at an uplink service port of the OLT network element to monitor the state of the OLT network element device, and forms a non-optical alarm output in a state where the optical signal is not acquired.
As a further preferred embodiment, the OLT network element monitoring device further includes an alarm unit, which reports an alarm to a central machine room when the monitoring unit monitors that the OLT network element device in the continuous offline state exists, and triggers a dispatch of a manual work to a field fault disposal process. For example, after monitoring for a predetermined time, if the OLT network element device in the offline state is still in the offline state, a corresponding alarm needs to be reported. The predetermined time may be 30 seconds, 1 minute, two minutes, etc.
As a further preferred embodiment, the OLT network element monitoring device is described above, wherein the operating device is at least one of a monitor, a keyboard, a mouse, a track pad, and a touch pad.
It should be noted that, the OLT network element monitoring device may configure multiple network cards and multiple IPs, and the device may simultaneously simulate the disconnection of multiple OLT network element devices.
Example two
As shown in fig. 2, the present application further provides an OLT network element monitoring system, wherein: the method comprises the steps of OLT network element equipment;
the OLT network element monitoring equipment is connected with the OLT network element equipment and is used for acquiring the state and basic parameters of the OLT network element equipment in the current network environment, forming monitoring data according to the state of the OLT network element equipment and forming a basic database according to the basic parameters;
illustratively, when the OLT network element monitoring device accesses the network environment, the OLT network element monitoring device may automatically obtain an IP address through a DHCP protocol or obtain an idle IP address through a method manually set by a user.
After the OLT network element monitoring device obtains the IP address, it implements communication connection between it and the OLT network element device and the network management server, and the OLT network element monitoring device scans the working states of multiple OLT network element devices in the current network environment at regular time.
And the network management server is connected with the OLT network element monitoring equipment and used for receiving the monitoring data under the action of the query request. When the OLT network element equipment is in an online state, the network management server can periodically query and update the common configuration and state information of the OLT network element equipment, such as the configuration information of network elements, ports and services, and state information of alarms, performance and the like, by sending an SNMP GET/SET message, and store the information locally.
When it is monitored that the OLT network element device is disconnected, for example, the PING packet is not connected or the uplink port optical fiber is not light, 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 device in the disconnected state, and receives a service request sent by the network management server to the disconnected OLT network element instead of the OLT network element device in the disconnected state, and meanwhile, the OLT network element monitoring device outputs a feedback value to form that the OLT network element is in the online state.
Further, the query of the network management service end to the offline OLT network element device may include network configuration, such as ifconfig, ping, netstat, and the like, and may also include operations of the network management service end to the OLT network element device, such as querying a network element port, service configuration, an alarm, and a performance state.
Illustratively, after receiving the network management request, the OLT network element device compares and searches the previously queried and stored network element data information, and forms a return message with the search result to feed back to the network management server, so as to provide the historical data of the OLT network element device when the OLT network element device is online before.
When the OLT network element monitoring device simulates the offline OLT network element device, it is further required to continue to monitor the state of the offline OLT network element device at regular time, for example, to change the IP of the OLT network element monitoring device back to the initial IP at regular time, and to monitor whether the IP of the offline OLT network element device in the existing management network has a response, or whether a no light alarm of an uplink port of the offline OLT network element device is cleared. And once the fact that the OLT network element equipment which is disconnected before is recovered to be on-line is monitored, stopping simulating the OLT network element equipment which is disconnected, changing the IP address of the OLT network element monitoring equipment back to the original configuration, and recovering the management of the network management server side on the real OLT network element equipment. The OLT network element monitoring equipment can report an alarm to a central machine room and trigger dispatching of workers to a field processing and troubleshooting process if the lost OLT network element equipment cannot be recovered on line all the time in the process of simulating the lost OLT network element equipment.
The method and the equipment for improving the offline performance of the network management of the OLT network element equipment can configure a plurality of network cards and a plurality of IPs, and can simultaneously simulate the offline condition of a plurality of OLT network element equipments.
Exemplify a specific embodiment
In an OLT network element monitoring system, OLT network element monitoring equipment is connected to a network environment, can discover each OLT network element equipment in the network environment, and can read configuration information in the OLT network element equipment through a network command and a snmp command. In addition, the OLT network element monitoring device may monitor whether the OLT network element devices are in a normal state, and maintain an information database related to the OLT network element devices and configuration information of the OLT network element devices in the network. The network environment can be further augmented by switches, which are devices connecting two or more segments of the same network (e.g., ethernet or token ring) using a common protocol, or routers, which can extend multiple devices using different layer-two network protocols. In the illustrated embodiment, the switch includes a plurality of communication ports for transmitting and receiving data and maintains a forwarding table associated with each port, each forwarding table including addresses (e.g., IP addresses and MAC addresses) of other OLT network element devices connected to the port.
The network management server is used for centralized management of OLT network element equipment, and the network management server at least comprises: a service terminal, the service terminal comprising: a communicator, a memory, and a processor.
The communicator is configured to be in communication connection with at least one piece of OLT network element equipment;
the memory for storing a computer program;
the processor is configured to execute the computer program stored in the memory, so that the service terminal performs a network element device management function. And
OLT network element equipment connected with a network management server can be called as a gateway network element, the gateway network element is directly connected with a service terminal, and the communication mode can be an in-band communication mode and an out-of-band communication mode; the in-band communication uses a network management channel based on communication channel bytes in a service frame as a physical channel; the out-of-band communication mode uses an external data communication network as a physical channel. In the illustrated embodiment, out-of-band communication is used. Generally speaking, a network management server and a network element device communicate with each other according to a Simple Network Management Protocol (SNMP), and the network management server can obtain information from the network element device through an SNMP message.
A plurality of OLT network element devices are accessed into the network environment by the switch, and more remote OLT network element devices can be accessed into the network through the Internet. The arrangement of the network environment allows any OLT network element device to exchange data with the OLT network element discovery/monitoring device in the network environment. Even more specific bridges may be connected to any number of computing devices or other network element devices, and the interactive network environment may include other types of network devices (e.g., routers, gateways, switches, hubs, and the like).
In the actual use process, the OLT network element equipment in the offline state is in a state of not being supervised by the network management server, and in the feedback data of the gateway server, the OLT network element equipment in the offline state is still in an "online" state, that is, the socks connected between the gateway server and the gateway network element are in a normal connection state. The gateway server will not send the connection monitoring command frequently. The OLT network element equipment in the dropped state may then only process the task before the response request is sent. And the network tasks to be accumulated process the reaction requests for completing the feedback responses. It can be understood that at this time, the OLT network element device only processes the task that it has received itself, and receives the task request sent from the outside after the task processing is completed. On one hand, the self-healing of the self-disconnection state can be realized, on the other hand, the OLT network element equipment only processes important tasks or events, and ignores the query request and intensively processes the important events by limited resources.
EXAMPLE III
As shown in fig. 3, the present invention provides a management method for OLT network element devices, and a network environment needs to be constructed before executing the management method for the OLT network element devices. Executing a management method of an OLT network element device in the network environment: the execution unit of the management method can be an OLT network element monitoring device, comprising,
step S110, forming an abnormal detection signal in the state of not receiving the inquiry response, and reading the mark information matched with the abnormal detection signal; specifically, the method comprises the following steps:
when the inquiry response does not receive the corresponding response message, the OLT network element equipment corresponding to the response message is judged to be in a disconnection state, and at the moment, the mark information of the OLT network element equipment in the disconnection state is read, wherein the mark information includes but is not limited to IP address information.
Illustratively, a method of timing PING packets or a method of monitoring optical fiber signals of the ports on the OLT network element devices may be adopted to determine whether the OLT network element devices are online.
When it is monitored that the OLT network element equipment is on-line, the common configuration and state information of the OLT network element equipment, such as configuration information of network elements, ports and services, state information of alarms, performance and the like, can be regularly inquired and updated by sending an SNMP GET/SET message, and the common configuration and state information is stored locally.
And step S120, forming a indexing signal according to the mark information, writing the indexing signal, and forming and outputting request feedback information matched with the service request. Specifically, the OLT network element monitoring device writes the IP address of the OLT network element device in the offline state into its own device, and at this time, 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, and meanwhile, the OLT network element monitoring device receives a service request (a service request sent by a gateway server), and returns a request feedback data matched with the service request to the network server.
In some embodiments, when it is monitored that the OLT network element device is online, the gateway server may further send an SNMP GET/SET message to periodically query and update common configuration and status information of the OLT network element device, such as configuration information of network elements, ports and services and status information of alarms and capabilities, and store the common configuration and status information in the local.
In some embodiments, when the PING packet is not transmitted or the uplink port optical fiber is not in the light state, it is determined that the OLT network element device is in a drop state, and the OLT network element monitoring device may temporarily change the IP of the OLT network element monitoring device to the IP address of the OLT network element device in the drop state, and receive the service request instead of the OLT network element device.
At this time, the OLT network element device in the offline state is in a state of not being supervised by the network management server, and in the feedback data of the gateway server, the OLT network element device in the offline state is still in an "online" state, that is, the SOCKET connection state between the gateway server and the gateway network element is normal. The gateway server does not send the connection monitoring command frequently. The OLT network element equipment in the dropped state may then only process the task before the response request is sent. And the network tasks to be accumulated process the reaction requests for completing the feedback response. It can be understood that at this time, the OLT network element device only processes the task that it has received itself, and receives the task request sent from the outside after the task processing is completed. On one hand, the self-healing of the self-disconnection state can be realized, on the other hand, the OLT network element equipment only processes important tasks or events, and ignores the inquiry request and processes the important events in a limited resource centralized way.
Specifically, the OLT network element monitoring unit finds that there is a dropped OLT network element device in the managed network environment, the state protection machine reads the IP address of the dropped OLT network element device first, assigns the IP address of the dropped OLT network element device to the IP address of the OLT monitoring unit itself, and the OLT monitoring unit receives a service request matched with the assigned IP address, and forms a request feedback message according to the service request as a responder and sends the request feedback message to an issuer of the service request. And the OLT network element equipment which is disconnected always processes other request tasks except the service request.
As a further preferred embodiment, the above method for managing an OLT network element device, includes: also comprises a step of adding a new type of additive,
step S130, writing initial mark information under the condition that the duration of the written index signal is matched with preset time; forming a detection mark matched with the abnormal detection signal, and forming a detection result according to the detection mark;
and step S140, outputting the detection result under the action of the initial mark information.
Specifically, when the OLT monitoring unit writes the initial address, the OLT monitoring unit may receive an SNMP query message sent by the gateway server. When the OLT monitoring unit receives the SNMP query message, a 'data transmission normal' signal and other similar information response SNMP query message sent by the network management server is formed according to the IP address of the OLT equipment in the offline state.
In short, the OLT monitoring unit switches between the monitoring function and the replacement of the lost OLT network element device, and the predetermined time matches the frequency of the OLT monitoring unit responding to the SNMP query message. In the switching process of the OLT monitoring unit, the gateway server side is prevented from frequently sending query commands. If the current OLT network element equipment is under the full-load work, the network of the terminal corresponding to the OLT network element equipment is in the disconnection state, and the whole network environment is in the unstable state, the method can avoid the frequent on-line and off-line of the OLT network element equipment, and reduce the burden of a gateway system.
And step S150, the OLT unit releases the mark information in the state of acquiring the response matched with the mark information. That is to say, the OLT network element device in the offline state has already recovered to be online, and at this time, the OLT monitoring unit does not need to switch its own working mode, and the OLT monitoring unit always works in the monitoring mode.
And if no response matching with the flag information is acquired, circularly executing the steps S110 to S140.
As a further preferred embodiment, the above method for managing OLT network element equipment is characterized in that: before reading the flag signal matching with the abnormal detection signal in a state where the abnormal detection signal is acquired, the method further includes:
step S109, polling the OLT network element devices in the current network environment, and acquiring the flag information associated with each OLT network element device. Specifically, the method comprises the following steps:
step S1091, polling online OLT network element equipment in the current network environment;
