Description

Access device management system and method

technical field

The present invention relates to the field of communication technology, in particular to a management system and method for access equipment.

Background technique

There are many types of optical edge access devices, including but not limited to SDH (Synchronous Digital Hierarchy, synchronous digital system), PDH (Plesiochronous Digital Hierarchy, quasi-synchronous digital system), PON (Passive Optical Network, passive optical network), ONU (Optical Network Unit, Optical Network Unit), ESR (Edge ServicesRouter, Edge Service Router), among which passive optical networks include EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network), BPON (Broadband Passive Optical Network, Broadband Passive Optical Network) , GEPON (Gigabit Ethernet Passive Optical Network, Gigabit Ethernet Passive Optical Network), GPON (GFP (Generic Framing Procedure, general framing procedure) Passive Optical Network, GFP Passive Optical Network), APON (ATM (Asynchronous Transfer Mode, asynchronous Transmission mode) Passive Optical Network, asynchronous transfer mode passive optical network), etc.

In the optical transmission system, the network management program (referred to as network management) completes the functions of real-time deployment of equipment services, alarm fault location, and online performance testing by issuing commands to equipment and querying equipment-related data. The distance is relatively short, and Ethernet cables or serial communication cables are generally used to connect. The channel for transmitting management information and data between optical edge access devices generally uses the same optical fiber physical channel as the business. The specific implementation depends on the optical edge access device. types, which are handled differently. For example, in SDH optical edge access equipment, it is established by regenerating part of the overhead bytes in the section and/or multiplexing section.

From the management of the above-mentioned optical transmission system and the transmission method of data information, it can be seen that when the optical edge access equipment is damaged, the optical fiber is damaged, or the optical edge access equipment is powered off (including power off of the equipment itself and equipment power failure caused by external power outages), From the perspective of the network management, it appears that the communication information of the network management is interrupted. For example, assuming that the optical edge access device B shown in Figure 1 is powered off, the optical edge access device A will report to the network management that there is no signal at the port connected to device B, and the network management will urgently display device B or device B The optical fiber to device A is damaged.

Because the geographical distribution of optical edge access devices is very wide, generally tens to hundreds of kilometers, and the number is large, when communication information is interrupted, it will generally cause a greater impact. Therefore, optical edge access devices are required to have high reliability. and when the communication information is interrupted, it needs to be dealt with in time as an emergency.

However, with the extension of optical edge access equipment to the end of the network (such as the use of private lines for large customers) or the gradual popularization of fiber-to-the-home, users may In this case, the optical edge access device is turned off. At this time, because the network management cannot correctly identify the damage of the optical edge access device or the information interruption caused by the power outage of the optical edge access device, it is necessary to manually query and confirm the cause of the interruption of communication information. A large amount and a long time-consuming will greatly increase the cost of network operation, management and maintenance; at the same time, it may cause problems that actually need to be dealt with in a timely manner that cannot be solved for a long time, affecting customer satisfaction.

Detailed ways

When the communication information between the network management and the access equipment is interrupted, in order to facilitate the network management to correctly determine whether the failure of the access equipment or the power failure of the access equipment, the present invention provides a management system for the access equipment. The access device is taken as an example for detailed description.

As shown in Figure 2, the system includes a device power supply status information reporting module and a device status management module.

The device power supply status information reporting module is set in the optical edge access device, and is respectively connected to the AC/DC input power supply and the internal power supply of the device in the optical edge access device. Its functions are:

Monitor the power supply status of the optical edge access equipment, construct corresponding equipment power supply status information and report it to the equipment status management module when a change in the power supply status is detected.

The device status management module is set in the network management, and its functions are:

According to the equipment power supply status information reported by the equipment power supply status information reporting module, the state management of the optical edge access equipment is performed.

Among them, the device power supply status information reporting module includes: a power outage information reporting submodule, which is connected to the AC/DC input power supply and the internal power supply of the device in the optical edge access device, and the device status management module includes: a power outage status management submodule;

The functions of the power outage information reporting sub-module are:

When a power outage of the optical edge access device is detected, the power outage information is constructed and reported to the power outage status management sub-module in the device status management module.

The functions of the power outage status management sub-module are:

After receiving the power outage information reported by the power outage information reporting sub-module, record the optical edge access device as a power outage state.

Wherein, the function of the power failure information reporting sub-module can be realized by the power failure monitoring unit and the power failure information reporting unit.

The power failure monitoring unit is set in the power supply part of the optical edge access equipment, and is respectively connected to the AC/DC input power supply and the internal power supply of the equipment in the optical edge access equipment. Its functions are:

When a power outage of the optical edge access device is detected, a power outage signal is generated, and the power outage signal is transmitted to the power outage information reporting unit.

The power failure information reporting unit is set in the business processing control part of the optical edge access device, and its functions are:

According to the received power failure signal, the power failure information is constructed and reported to the power failure status management sub-module.

Wherein, the power failure monitoring unit may be composed of a power failure monitoring subunit and an energy storage subunit.

The power failure monitoring subunit is connected with the AC/DC input power supply and the energy storage subunit, and its functions are:

When a power outage of the optical edge access device is detected, a power outage signal is generated, and the power outage signal is transmitted to the power outage information reporting unit;

The energy storage subunit is respectively connected to the AC/DC input power supply and the internal power supply of the equipment in the optical edge access equipment, and its functions are:

Store a certain amount of electric energy, and supply power to the power outage monitoring subunit and power outage information reporting unit when the optical edge access device is out of power, so that the power outage monitoring subunit and power outage information reporting unit can continue to work for a period of time to ensure that the power outage monitoring subunit generates power outages signal and transmit the power failure signal to the power failure information reporting unit, and the power failure information reporting unit constructs power failure information according to the power failure signal and reports it to the power failure status management sub-module.

The energy storage subunit can be composed of energy storage devices such as capacitors.

The time for the energy storage subunit to provide normal power supply for the power failure monitoring subunit, the power failure information reporting unit and the communication part of the equipment after the equipment power failure is related to the information amount of the reported information and the selection of the transmission channel of the reported information. In the present invention, The management and data information channel between the optical edge access device and the network management can be used as the transmission channel for reporting information.

For example, in the SDH system, if the length of the power failure information is calculated as 60 bytes (in order to facilitate encapsulation into an Ethernet packet), when using the three overhead bytes defined as digital communication path bytes in the regeneration section as management information and data channels , it takes at least 2.5 milliseconds to transmit 60 bytes, plus the time it takes for the power outage information reporting unit of the optical edge access device to report the power outage information, so the energy storage subunit is best able to report the power outage monitoring The subunit, the power failure information reporting unit and the communication part continue to provide normal power supply for more than 10 milliseconds.

When the optical edge access device is powered off, in order to prevent the energy storage sub-unit from discharging externally and ensure that the power-off monitoring sub-unit and the power-off information reporting unit complete the necessary work, the power-off monitoring unit can also include an isolation sub-unit, which is set between the power-off monitoring sub-unit and the power-off monitoring sub-unit. The energy storage subunits are directly connected to the AC/DC input power supply, and the power failure monitoring subunit also needs to be directly connected to the AC/DC input power supply.

The isolation subunit may be composed of switching devices such as diodes and/or triodes and/or auxiliary circuits.

Since the power failure signal can be generated through the contacts associated with the power switch, for example, for a multi-contact power switch, when the light edge access device is powered off, the power failure signal can be generated by directly or indirectly using some of the contacts, so , The power failure monitoring subunit can be replaced by a multi-contact power switch.

In addition, the power failure monitoring unit may also be composed of a time-delayed power-off switch.

When the optical edge access device actively cuts off the power supply, the group contact power switch or the delayed turn-off power switch will generate a power failure signal and transmit it to the power failure information reporting unit.

However, the scheme of generating a power failure signal through multiple sets of contact power switches or delayed shutdown of the power switch has certain limitations. The power switch cannot generate a power failure signal, resulting in the network management being unable to receive the power failure information.

In order to facilitate the network management to timely and accurately judge whether the optical edge access device is in a fault state, on the basis of the above-mentioned system, a fault state management module is set in the network management, and is connected with the device state management module. Its functions are:

According to the no-signal alarm of the connection port with the optical edge access device received by other devices and the power failure status information of the access device, the access device is recorded as a non-fault state.

In order to simplify the processing work of the network management, on the basis of the above system, the device power supply status information reporting module may also include a power-on information reporting sub-module, and the device status management module may also include: power-on status management sub-module;

The functions of the power-on information reporting sub-module are:

When it is detected that the optical edge access device is powered on again, the power-on information is constructed and reported to the power-on state management submodule.

The functions of the power-on state management sub-module are:

According to the power-on information reported by the power-on information reporting sub-module, the optical edge access device is recorded as a power-on state.

In order to have a further understanding of the present invention, a detailed description will be given below in conjunction with the above-mentioned system of the present invention for identifying the power failure of the optical edge access device and the method of the present invention.

The specific implementation of the method of the present invention is shown in Figure 3, comprising the following steps:

Step 31: When the optical edge access device is powered off, the power failure monitoring subunit cannot receive the AC/DC input power, so it generates a power failure signal and transmits it to the power failure information reporting unit.

Step 32: The power failure information reporting unit constructs power failure information after receiving the power failure signal, and sends the power failure information to the power failure state management submodule through the management and data information channel between the optical edge access device and the network management.

Because the energy stored in the energy storage subunit is limited, in order to improve the response time of the optical edge access device during power failure, the transmission between the power failure monitoring subunit and the power failure information reporting unit, and the communication between the power failure information reporting unit and the power failure status management submodule The transmission between them should be as fast as possible; and the power failure information reported by the power failure information reporting unit to the power failure state management sub-module should also be simplified as much as possible, such as only including necessary information such as power failure identification and equipment code. Of course, it can also be based on design needs. , to add other auxiliary information.

In addition, in order to improve the reliability of power failure information reporting, the power failure information reporting submodule can repeatedly send the power failure information of the device to the power failure state management submodule of the network management unit before the energy of the energy storage subunit is exhausted.

Step 33: After receiving the power outage information, the power outage state management submodule confirms that the optical edge access device is in the power outage state, and records the device as the power outage state.

Step 34: When the fault state management module receives an alarm sent by other devices that the port connected to the optical edge access device has no signal, according to the power failure status information of the access device, record the optical edge access device as not failure state.

Step 35: When the optical edge access device is powered on again, the power-on information reporting submodule constructs the power-on information, and reports and sends the power-on information to the power-on status management submodule through the management and data information channel between the optical edge access device and the network management .

The power-on information can include necessary information such as power-on identification and equipment code, and of course, other auxiliary information can also be added according to design requirements.

Step 36: After receiving the power-on information, the power-on state management submodule confirms that the device is in the power-on state, and promptly records the device as the power-on state.

In the present invention, the data transmission format of the power outage information and power-on information reported by the optical edge access device to the network management is not limited, usually according to the Q. 921 constructs the data link layer, and constructs the network layer according to the 8473 protocol of ISO (International Organization for Standardization, International Organization for Standardization).

The present invention is applicable to various types of optical edge access equipment, including but not limited to: SDH, PDH, ONU, ESR, PON, BPON, GEPON, GPON, APON and other optical edge access equipment.

As shown in Figure 1, assume that the optical edge access device B is powered off, and the communication information between the network management and device B is interrupted. At the same time, device A will report to the network management an alarm that the port connected to device B has no signal.

If the network management receives the power outage information reported by device B, the network management can judge that the alarm that the port connected to device B has no signal reported by device A may be caused by the power failure of device B, and there is no need to urgently display device B or device B to The fiber between device A is damaged, and to deal with it, just record device B as a power outage.

If the network management does not receive the power outage information reported by device B, it will urgently display that device B or the optical fiber between device B and device A is damaged, and handle accordingly.

When device B is powered on again, device B sends power-on information to the network management, and the network management can know that device B is powered on, and then deal with the alarm reported by device A that there is no signal at the port connected to device B according to the existing technology.

Therefore, adopting the system and method of the present invention can greatly reduce the workload and cost of optical transmission network operation, management and maintenance, and can promptly deal with optical edge access equipment failures and fiber failures, which is conducive to improving service quality and increasing customer satisfaction , so as to realize the purpose of simplifying network management and improving service level.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changes or Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
