Detailed Description
So that the manner in which the features and elements of the disclosed embodiments can be understood in detail, a more particular description of the disclosed embodiments, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings. In the following description of the technology, for purposes of explanation, numerous details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, one or more embodiments may be practiced without these details. In other instances, well-known structures and devices may be shown in simplified form in order to simplify the drawing.
When the optical line terminal is connected with too many optical network units, the memory resource and the CPU resource of the whole system are insufficient, which affects the normal operation of the equipment, and more redundant information appears, which brings inconvenience to the maintenance of the system. If the invalid optical network unit is searched and deleted through manual operation, the method is extremely difficult to realize in an actual operation environment. The embodiment of the disclosure provides a method for automatically detecting and replacing invalid optical network units, which can automatically detect and delete the invalid optical network units existing in a system when the number of the optical network units bound in the system reaches the maximum number supported by an optical line terminal, so that a newly accessed optical network unit can be normally registered, and great convenience is brought to the operation of a user.
In a first aspect, an embodiment of the present disclosure provides an automatic detecting and replacing method for an invalid optical network unit, and the following will describe in detail the automatic detecting and replacing method for an invalid optical network unit provided in the embodiment of the present disclosure with reference to fig. 1 to fig. 3.
Referring to fig. 1, the method specifically includes the following steps.
S101, acquiring the number of the optical network units bound in the current system according to the fact that a new optical network unit is detected to be accessed.
The optical network unit is a customer premise equipment in the EPON system, is used for connecting a user PC, a set-top box, a switch, and the like, is usually placed at the home, at a corridor or on both sides of a road of a user, and is responsible for responding to a management command sent by an optical line terminal and forwarding user data to the optical line terminal.
The optical line terminal is a core device in an EPON system, and is generally placed in a central machine room, and is used for uniformly managing optical network units and aggregating and transmitting access services to an IP network.
One optical line terminal is provided with a plurality of optical network unit interfaces, but due to the limitation of chip resources and the like, the number of the optical network unit interfaces has an upper limit, and when the access upper limit is reached, a newly accessed optical network unit cannot be normally registered. However, in the case of automatic binding, an unlimited access situation often occurs.
Therefore, when detecting that a newly accessed optical network unit exists in the system, the number of the optical network units bound in the current system is firstly obtained, and whether the currently accessed optical network unit reaches the maximum specification or not is judged according to the number.
And S102, binding the newly accessed optical network units according to the condition that the number of the bound optical network units is less than the maximum number supported by the optical line terminal.
Specifically, when the number of the bound onu is less than the maximum number supported by the olt, a new onu interface is automatically generated and the automatic binding is issued, and the newly accessed onu is successfully brought on line.
Further, after the newly accessed optical network unit comes online, the method further includes: and recording the on-line time, the off-line time, the uplink flow in a preset time period and the on-off state of the user side interface of the optical network unit.
A person skilled in the art may set the preset time period by himself, and the embodiment of the present disclosure is not limited specifically, for example, the uplink traffic within 24 hours of the on-line of the optical network unit is recorded, and whether the optical network unit is invalid is determined according to the recorded traffic data.
According to this step, when the accessed optical network unit does not reach the maximum specification, the newly accessed optical network unit can be automatically bound.
And S103, detecting whether invalid optical network units exist in the system according to the fact that the number of the bound optical network units is larger than or equal to the maximum number supported by the optical line terminal.
The invalid optical network unit refers to an idle optical network unit such as an offline optical network unit, a failed optical network unit, and an optical network unit without user access.
Because the optical module at the optical line terminal side needs to be frequently plugged and unplugged at the access end of the optical network unit equipment and the optical network unit is also frequently accessed in the environment, the optical network unit interface under one optical line terminal interface can exceed the upper limit after being plugged and unplugged for many times, wherein a plurality of off-line optical network units or optical network units without user access are not lacked. The invalid optical network units occupy the access ports, when the number of the bound optical network units is greater than or equal to the maximum number supported by the optical line terminal, the newly accessed optical network units cannot be normally registered, and when the number of the invalid optical network units in the system is large, the memory resources and the CPU resources of the whole system are insufficient, the normal operation of equipment is influenced, more redundant information also appears, and the inconvenience is brought to the maintenance of the system.
Specifically, when the number of the bound onu is greater than or equal to the maximum number supported by the olt, whether an invalid onu exists in the system may be automatically detected according to the offline time of the onu, the uplink traffic within a preset time period, and the on-off state of the customer-side interface.
Specifically, it is first determined whether an offline onu exists in the system, and when an offline onu exists in the system, the onu with the longest offline time is marked as an invalid onu according to the recorded offline time.
When the off-line optical network unit does not exist in the system, whether the optical network unit is an invalid optical network unit is judged according to the switch state of the user side interface of the optical network unit, the switch state of the user side interface of the optical network unit is traversed, and the optical network unit with the switch state of the user side interface being closed is marked as the invalid optical network unit.
When the optical network unit with the user side interface in the closed switch state does not exist in the system, whether an invalid optical network unit exists is judged according to the recorded uplink flow in the preset time period, and the uplink flow in the preset time period after the optical network unit is on line is firstly obtained, wherein the preset time period is not specifically limited in the embodiment of the disclosure, and can be set by a person skilled in the art by himself, for example, the uplink flow in 24 hours after the optical network unit is on line is counted, and the optical network unit with the uplink flow of zero is marked as the invalid optical network unit.
And when the optical network unit with the uplink flow of zero in the preset time period does not exist, determining that no invalid optical network unit is detected in the current system.
Fig. 3 is a flowchart illustrating a method for detecting an invalid optical network unit according to an exemplary embodiment, which includes automatically replacing a loose mode and a strict mode, as shown in fig. 3:
when the optical network unit reaches the maximum specification, firstly executing a loose mode, judging whether an off-line optical network unit exists, if so, marking the optical network unit with the longest off-line time as an invalid optical network unit.
And when the off-line optical network unit does not exist, traversing the switch states of the user side interfaces of the optical network unit, judging whether the optical network units with the user side interfaces in the closed switch states are all closed, and if so, marking the optical network units with the user side interfaces in the closed switch states as invalid optical network units.
When the optical network unit with the user side interface in the closed switch state does not exist, judging whether to execute a strict mode, if so, judging whether the uplink flow of the optical network unit within 24 hours on line is zero, if so, marking the optical network unit as an invalid optical network unit, and if not, determining that the invalid optical network unit is not detected. Wherein the preset time length can be set by a person skilled in the art.
If the strict mode is not executed, it is determined that no invalid optical network unit is detected.
According to the step, whether invalid optical network units exist in the system can be automatically detected, and the operation of users is greatly facilitated.
And S104, deleting the invalid optical network unit and binding the newly accessed optical network unit according to the invalid optical network unit in the system.
Specifically, the invalid onu is deleted to obtain an idle onu interface, and the automatic binding is issued, and the newly accessed onu is successfully brought on line.
Further, when it is determined that no invalid onu is detected in the current system, the newly accessed onu cannot register, and only the newly accessed onu is set as the silent onu, and the occurrence of the invalid onu is waited.
In a possible implementation manner, the system periodically detects whether an invalid onu exists, for example, the system detects whether an invalid onu exists every three minutes, and when an invalid onu exists in the system, the invalid onu is deleted and the quiet onu is automatically bound, so that the newly added onu is successfully brought online.
In order to facilitate understanding of the automatic detection and replacement method of the invalid optical network unit provided in the embodiment of the present application, the following description is made with reference to fig. 2. As shown in fig. 2, the method includes:
and when the optical network unit is detected to be accessed, judging whether the optical network unit is successfully bound, and if the optical network unit is successfully bound, successfully connecting the optical network unit. And if not, judging whether the number of the bound optical network units in the current system reaches the maximum number supported by the optical line terminal.
And when the number of the bound optical network units does not reach the maximum number supported by the optical line terminal, sending the optical network unit interface, sending the automatic binding, and successfully getting the newly accessed optical network unit on line.
When the number of the bound optical network units reaches the maximum number supported by the optical line terminal, an invalid optical network unit is searched, and whether the invalid optical network unit exists in the system can be detected according to the off-line time of the optical network unit, the uplink flow in a preset time period and the on-off state of the user side interface. If the invalid optical network unit existing in the system is detected, deleting the invalid optical network unit to obtain an idle optical network unit interface, and issuing automatic binding, wherein the newly accessed optical network unit is successfully on line.
If the invalid optical network unit is not detected, setting the newly accessed optical network unit as a silent optical network unit, waiting for the occurrence of the invalid optical network unit, deleting the occurred invalid optical network unit and automatically binding the newly accessed optical network unit.
Based on the automatic detection and replacement method of the invalid optical network unit provided by the embodiment of the disclosure, the invalid optical network unit existing in the system can be automatically detected and deleted, so that the newly accessed optical network unit can be normally registered, and great convenience is brought to the operation of a user. And invalid optical network units existing in the system are deleted in time, so that the problem that the normal operation of equipment is influenced due to insufficient system resources caused by more accessed optical network units is solved.
