With the rapid development of the Internet, high-quality services such as 8K video, online education, cloud VR and the like are generated, and the services have high requirements on high bandwidth and low time delay, so that the FTTR is generated, and compared with the traditional FTTH optical fiber for home, the FTTR realizes the full-house gigabit WIFI coverage capability, and solves the bad user experience caused by insufficient FTTH bandwidth and poor coverage.
The FTTR technology brings high bandwidth coverage and introduces more ONU application scenarios. The traditional ONU management means utilizes the OLT local side to issue a command of a P2P mode to the ONU terminal so as to complete various service configuration and management. If the space covered in the FTTR is larger, the number of required terminals is larger, and when the ONU fails, ensuring that positioning and service recovery are performed by a fast and effective method has become an urgent need to be solved. Particularly, when the ONU reaches a considerable amount, the complex networking is overlapped, various faults can not be avoided to cause abnormal service, the number of terminals is large at the moment, the specific ONU equipment is not known, the faulty ONU equipment is usually positioned in a manual detection mode at present, and the fault positioning cost is high.
In view of the above problems, the present application proposes the following embodiments. The following describes a method and an apparatus for positioning an optical network unit fault provided by an embodiment of the present invention with reference to fig. 1 to 5.
Fig. 1 is a flow chart of an optical network unit fault location method provided by the present invention, as shown in fig. 1, where the optical network unit fault location method is applied to an optical line terminal, and includes, but is not limited to, the following steps:
s110, under the condition that the destination optical network unit is determined, a first link detection message is sent, wherein the first link detection message comprises unique identification information of the destination optical network unit.
Here, in FTTR networking, at least one OLT is included, where each OLT includes at least one virtual domain, that is, one OLT includes one or more virtual domains, each virtual domain manages a plurality of ONUs, and ONUs in any one virtual domain are networked in a tree topology. The OLT stores a tree topology of its subordinate ONUs, that is, when the OLT includes N virtual domains, the ONUs in each virtual domain are networked in a tree topology, and the OLT stores the N tree topologies. It will be appreciated that, in order to distinguish the tree topology of each virtual domain, the OLT further stores unique identification information of each virtual domain (hereinafter, each embodiment is denoted by a virtual domain ID), and each tree topology of each virtual domain is associated with unique identification information of a corresponding virtual domain.
Here, the ONUs of each virtual domain may select an appropriate tree structure according to the actual use requirement to perform networking, which is not limited herein.
For easy understanding, the following embodiments take an OLT including a virtual domain as an example, and describe an optical network unit fault locating method and an optical network unit data transceiving method provided in the present application.
Here, the OLT may store a virtual domain ID to which each ONU belongs, unique identification information of each ONU, a service configured on each ONU, a parent-child relationship of each ONU, and the like.
In an embodiment, the unique identification information of the ONU is the MAC address of the ONU.
In another embodiment, the unique identification information of the ONU is a customized ONU ID (hereinafter referred to as ONU-ID), and the ID may be a letter, a number, or a combination of a letter and a number, which is not limited herein. It is understood that ONU-IDs in the same virtual domain may be different, and ONU-IDs in different virtual domains may be the same or different.
For ease of understanding, the following embodiments unify the MAC address of an ONU as unique identification information of the ONU.
Here, when the destination optical network unit is determined, that is, the MAC address of the destination ONU is determined, in a home networking scenario, one ONU device is usually used in one room, and when a network failure in one room is determined, the MAC address of the ONU device in the room can be found by searching, and then the ONU in the room is used as the destination ONU, and the MAC address is determined as the destination MAC address. At this time, the first link detection message may be sent in a unicast manner, that is, the first link detection message carries a MAC address of a destination ONU (abbreviated as a destination MAC address), and the ONU that receives the first link detection message determines whether the MAC address of itself is the same as the destination MAC address in the first link detection message, and if not, forwards the first link detection message to the designated node, so as to implement detection of a link state from the root node to the destination ONU device.
Here, the first link detection message is a two-layer ethernet message forwarded based on the MAC address in a specified virtual domain, where the first link detection message carries the virtual domain ID of the virtual domain and the destination MAC address. The first link detection message may also carry a type ID of the first link detection message, where the type ID of one message indicates a type of the message, for example, the type ID of the message sending data in normal communication is A1, the type ID of the message sending data in fault detection is C1, the type ID of the message responding to the data in fault detection is C2, and the type IDs of the first link detection message, the second link detection message and the third link detection message described below are both C1, and the type IDs of the link detection response messages are both C2.
S120, after receiving the link detection response message returned by the subordinate optical network unit, determining a fault area based on each link detection response message and the tree topology structure, wherein the link detection response message comprises the unique identification information of the corresponding optical network unit.
Here, the link detection reply message returned by the receiving subordinate optical network unit is the link detection reply message returned by all the receiving subordinate optical network units in the virtual domain. It may be understood that the link detection reply messages returned by all the optical network units include link detection reply messages returned by ONUs capable of normally communicating, and for an ONU in a fault area and each descendant node of the faulty ONU, the link detection reply message returned by the ONU cannot be obtained, which may not be received, or may not be sent to the nodes by the first link detection message.
Optionally, setting a response time threshold, the OLT starts to count after sending the first link detection message, and if the counted time reaches the response time threshold, considers that all link detection response messages returned by the ONUs capable of normal communication have been received, and executing the subsequent step of determining the fault area.
Here, because the ONUs in the fault area and the link detection response messages of the descendant nodes thereof cannot be received, after the ONUs receiving the link detection response messages are compared with the tree topology structure, it is possible to determine which ONUs do not receive the link detection response messages, thereby determining the fault area.
According to the optical network unit fault positioning method provided by the embodiment of the application, an optical line terminal stores a tree topology structure of an optical network unit subordinate to the optical line terminal, and under the condition that a target optical network unit is determined, the optical line terminal sends a first link detection message which comprises unique identification information of the target optical network unit; after receiving the link detection response message returned by the subordinate optical network unit, determining a fault area based on each link detection response message and the tree topology structure, wherein the link detection response message comprises the unique identification information of the corresponding optical network unit. The link detection is initiated through the first link detection message, the link detection response message returned by each optical network unit is compared with the pre-stored tree-shaped networking structure of the optical network units, and the optical network units which do not return the link detection response message are determined, so that the fault area is quickly locked, the fault investigation is not needed to be performed manually, a user is helped to search the optical network units remotely, the operation condition of the optical network units is obtained, the fault position can be determined preliminarily when the fault occurs, the cost of fault positioning is reduced, the fault maintenance recovery time is saved, and the user experience is improved.
In an optional embodiment, the optical network unit fault location method further includes:
and under the condition that the target optical network unit is not determined, sending a second link detection message, wherein the second link detection message comprises broadcast address identification information which indicates all subordinate optical network units of the optical line terminal.
Here, in the case where the destination optical network unit is not determined, that is, the area where the network failure is not determined, it is necessary to traverse all ONUs in the virtual domain, and from the root node of the tree topology, the second link detection message is forwarded to the last node without destination, that is, it is necessary to send the second link detection message to each ONU, so that each ONU returns a link detection response message, thereby detecting the link states of all ONUs in the virtual domain. At this time, the second link detection message may be sent in a broadcast manner, where the second link detection message carries broadcast address identification information, typically, an FF-FF MAC address, to indicate that all nodes receiving the second link detection message need to receive and process the second link detection message, and specifically, an ONU receiving the second link detection message needs to forward the second link detection message to its child node, and return a link detection response message to the OLT.
In some embodiments, the first link detection message is the same as the second link detection message except that the destination MAC address is different, the destination MAC address of the first link detection message is the MAC address of the destination ONU, and the destination MAC of the second link detection message is FF-FF.
According to the optical network unit fault positioning method, under the condition that the fault area cannot be determined, the link states of all nodes in the virtual domain are detected in a broadcast mode, so that the fault position is locked rapidly, the fault maintenance recovery time is saved, and the user experience is improved.
Based on any one of the above embodiments, the optical network unit fault location method further includes:
and under the condition of determining the service path, sending a third link detection message, wherein the third link detection message comprises the subnet number of the service path.
Here, in the case of determining a service path, that is, a specific service failure is known, a specific service path needs to be detected, and the third link detection packet is forwarded according to the mac+vlan, which is equivalent to detecting a specific service path.
Fig. 3 is a schematic structural diagram of an FTTR network provided in the present invention, as shown in fig. 3, for example, from node 7 through node 3, node 1 to OLT are a service carried by VLAN100 (subnet VLAN number is 100), when the service fails, detection is initiated in a virtual domain according to mac+vlan100 of node 7, the OLT sends a third link detection packet, which includes the MAC address of node 7 and the subnet number VLAN100 of the service path, and the third link detection packet is detected by routing VLAN100 through node 1, node 3 and node 7, and if the third link detection packet is received, the node whose subnet number is not VLAN100 in the virtual domain can be directly discarded without forwarding. For example, if a broadband service of a user fails, the broadband service is configured by VLAN100, and the third link detection message carries VLAN100, a node that does not configure VLAN100 will not pass through the third link detection message.
According to the optical network unit fault positioning method, when a specific service fault is known, the link state of the target ONU is detected through the third link detection message carrying the MAC address and the subnet number of the target ONU, the nodes which do not belong to the corresponding subnet numbers do not need to transmit the third link detection message, the third link detection message in the virtual domain is reduced, and the power consumption of the whole virtual domain is reduced.
Based on any one of the foregoing embodiments, the determining a fault area based on each link detection reply packet and the tree topology includes:
if the optical line terminal receives the first link detection response message and does not receive the second link detection response message, determining that the fault area is a network area between the first optical network unit and the second optical network unit;
the first link detection response message includes unique identification information of the first optical network unit, the second link detection response message includes unique identification information of the second optical network unit, and the first optical network unit is a parent node of the second optical network unit.
Here, after the OLT receives all the link detection response messages, because the OLT itself stores the basic information (unique identifier of the ONU, ID of the virtual domain to which the ONU belongs) and the topology structure of each ONU in the virtual domain, in combination with the virtual domain ID and the MAC address in the link detection response message, the message path can be analyzed, so as to obtain the path information of the whole detection.
Referring to fig. 3, if there is a fault in the path from the OLT initiator to the destination ONU, the node downstream of the fault point cannot receive the link detection message, whether the first link detection message, the second link detection message, or the third link detection message, and the node downstream of the fault point does not reply to the link detection response message, so that the OLT can determine the position of the fault point according to the received link detection response message. For example, when the spatial network where the node 8 is located is abnormal, the OLT initiates a first link detection message, where the destination MAC address in the first link detection message is the MAC address of the node 8, and if the OLT can receive the link detection response messages replied by the node 2 and the node 5, but cannot receive the link detection response messages replied by the node 8, the path formed by the OLT is: the main route- > node 2- > node 5, where the olt determines that the area between the node 5 and the node 8 is faulty, the link detection reply message replied by the node 5 is the first link detection reply message, and the link detection reply message replied by the node 8 is the second link detection reply message, where the spatial network abnormality where the node 8 is located may be a network line fault between the node 5 and the node 8, or a fault of the node 5 or the node 8 itself, or a service fault configured on the node 5 or the node 8, or the like. If the OLT can receive the link detection response message replied by the node 2, but cannot receive the link detection response messages replied by the node 5 and the node 8, the path formed by the OLT is: the method comprises the steps that a main route is changed to node 2, the OLT judges the region fault between the node 2 and the node 5, the link detection response message replied by the node 2 is a first link detection response message, and the link detection response message replied by the node 5 is a second link detection response message.
It will be appreciated that the second link detection reply message may not be a true message, and the second optical network unit may not be able to reply to the link detection reply message due to the failure, where the second link detection reply message is a message that the OLT expects to receive.
According to the optical network unit fault positioning method, the optical line terminal analyzes the link path based on the received link detection response message and compares the link path with the pre-stored topological structure, so that a fault area is determined, remote searching of the ONU is realized, the fault position is preliminarily determined, the fault maintenance time is shortened, and the fault maintenance efficiency is improved.
Based on any of the above embodiments, after the OLT completes the detection, a corresponding command query detection result is provided, and the analyzed path information is provided with visual information.
