Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the following describes specific technical solutions of the present invention in further detail with reference to the accompanying drawings in the embodiments of the present invention. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a flowchart illustrating a management method of an optical network unit according to an embodiment of the present invention. As shown in fig. 1, the method specifically includes:
s101: receiving an access request of a first ONU under the condition that the first ONU completes standard registration; the access request comprises identification information of a virtual domain to be accessed; the first ONU is any one of the plurality of ONUs; the virtual domain to be accessed can be used for managing at least one ONU in the plurality of ONUs in the first subsystem.
It should be noted that the method may be applied to an optical network communication system, where the optical network communication system includes at least one subsystem, and a first subsystem in the at least one subsystem includes a plurality of optical network units ONU, where the first subsystem is any one of the at least one subsystem, and may specifically be an FTTR system in which a plurality of ONUs enter a user home or other use environment, and the FTTR system may meet current mainstream home entertainment and interconnection needs, and simultaneously bring high bandwidth and large capacity support capabilities of an optical fiber channel, such as needs of home Virtual Reality (VR) entertainment, a high-speed internet of things, and a real-time network experience. The management method provided by the embodiment of the invention can be used for conveniently managing the ONUs.
In the actual application process, the standard registration may refer to a registration process of a PON system such as a standard G/EPON, 10GEPON, XPON, and the like, where the standard registration may refer to a registration operation required when a newly connected or offline ONU re-accesses to the PON system. Taking registration to the G/EPON system as an example to explain a standard registration process, the specific process may roughly include: the ONU sends a registration request frame to the OLT; after receiving the registration request frame, the OLT carries out processing and sends a registration authorization frame and a registration frame to the ONU; then, after receiving the registration authorization frame and the registration frame, the ONU feeds back a registration confirmation frame to the OLT. That is to say, the standard registration is the same as the process of registering the ONU in the G/EPON system in the existing G/EPON management model, and the method provided in the embodiment of the present invention is based on that, after the ONU completes the standard registration, the specific process of the standard registration and the specific contents of the registration request frame, the registration authorization frame, the registration frame, and the registration confirmation frame are not described herein again.

The virtual domain to be accessed may be configured for the OLT in the optical network communication system, or may be created for the OLT in the optical network communication system, and may be configured to manage any ONU in the first subsystem. The identification information may be an identification number (ID), for example, a virtual domain ID. In an actual application process, the virtual domain to be accessed may be created by an OLT at an initial stage of the construction of the optical network communication system, that is, the virtual domain to be accessed is created for the OLT. It can be understood that, at the beginning of creation, the OLT configures basic attributes of the virtual domain to be accessed, such as identification information, an account and a password, an encryption manner, a member role, a service model, and the like, and an initial operating state of the virtual domain to be accessed, where the identification information may be the aforementioned identification number. The account and the password may be an account name and a password used when the OLT creates the virtual domain to be accessed and accesses the virtual domain to be accessed. The encryption mode may be an encryption mode of the password to be accessed to the virtual domain. The member role may be a type classification of the ONU managed by the OLT for the virtual domain to be accessed, where the type classification is associated with a networking mode required in the first subsystem, for example, if a tree network structure is adopted during networking, the member role in the virtual domain to be accessed may include a trunk role, a branch role, an end role, and the like, and the trunk role is located at a trunk node of the tree network; the branch roles are located at branch nodes of the tree network; the end roles are located at end nodes of the tree network. The service model is associated with the member roles, for example, the ONUs at different positions in the aforementioned tree network, and then the objects served by the service model may be different, so as to determine the services required to be configured.
It should be noted that, the execution main body here may be an OLT, that is, for S101, it may mean that, when the first ONU completes standard registration, the OLT receives an access request sent by the first ONU, where the first ONU sends the access request to the OLT through a set Virtual Remote Control Protocol (VCRP), where the VCRP is a Protocol specially set to implement the method provided in the embodiment of the present invention, and is mainly responsible for Remote interaction and Control between the OLT and the Virtual domain, and between the OLT and the ONU, and specifically, the following may be used: 1) controlling and managing: the OLT controls and manages the virtual domain through the VCRP; 2) and the ONU performs information interaction with the OLT through the VCRP, such as information interaction in authentication and alarm processes. The message format of the information in the transmission process based on the VCRP may include: a destination Media Access Control (MAC), a source MAC, a message Type (Type), a Payload (Payload), and a check, where the destination MAC may carry identification information of a virtual domain. The message Type is a custom Type, the custom Type indicates that VCRP is adopted for transmission, the Payload may be a bearer segment of a specific attribute, and follows a Type-Length-Value (TLV) structure, which includes an attribute item, an index item, a Length, and a Payload, wherein different attribute items represent different contents, specifically, the attribute item may set 4 bytes, and different attribute items may be 0x0001-0x0fff, and a virtual domain global configuration attribute is effective for all ONU members managed in a virtual domain; 0x1000-0x1fff, aiming at the configuration of the main nodes under the condition that the virtual domain adopts a tree network; 0x2000-0x2fff, aiming at the configuration of the branch nodes under the condition that the virtual domain adopts the tree network; 0x3000-0x3fff, aiming at the configuration of terminal nodes under the condition that a virtual domain adopts a tree network; 0xe000-0xefff, configuring a virtual domain alarm and notification message, and sending the message to the OLT by the virtual domain. The terminal node referred to herein is also the aforementioned terminal node. The index item can be set to 4 bytes; the length can be set to 2 bytes; payload may be set to 40-1500 bytes.

And after the identification information is obtained, judging whether the virtual domain to be accessed is legal or not based on the identification information. Specifically, the determining whether the virtual domain to be accessed is legal based on the identification information may include: the OLT takes the identification information as an index and searches a table stored by the OLT and used for establishing a mapping relation between the virtual domain and the identification information so as to judge whether the virtual domain to be accessed is legal or not; when the identification information is searched in the mapping relation table of the created virtual domain, judging that the virtual domain to be accessed is legal; and under the condition that the mapping relation table of the created virtual domain does not search the identification information, judging that the virtual domain to be accessed is illegal.
In some embodiments, when it is determined that the virtual domain to be accessed is legal, performing authentication processing on the first ONU, and obtaining an authentication result, where the performing authentication processing on the first ONU and obtaining an authentication result may include: performing authentication processing through the VCRP to obtain an authentication result, specifically, sending, by the first ONU, an authentication request message carrying the account and the password of the virtual domain to be accessed to the OLT; the authentication request message is packaged based on the VCRP; the OLT receives the authentication request message, analyzes the authentication request message, obtains the account and the password, takes the account and the password as indexes, and searches in a table storing the corresponding relation between the created virtual domain and the account and the password to obtain the authentication result; searching the account and the password in a corresponding relation table in which the account and the password of the created virtual domain are stored, wherein the authentication result is successful; and searching the account and the password in a corresponding relation table in which the account and the password of the created virtual domain are stored, wherein the authentication result is authentication failure.
Here, when the authentication result is that the authentication is successful, determining an operating state of the virtual domain to be accessed, where the operating state includes an idle state and an active state, and in some embodiments, determining an access mode matched with the first ONU based on the operating state may include:

when the operating state is the activated state, the access mode matched with the first ONU is as follows: and directly accessing the first ONU to the virtual domain to be accessed.
What is expressed here is: when the virtual domain to be accessed is in an idle state, if the authentication result is successful, converting the running state of the virtual domain to be accessed into an activated state, and then accessing the first ONU into the virtual domain to be accessed; and if the virtual domain to be accessed is in an activated state, directly accessing the first ONU to the virtual domain to be accessed if the authentication result is successfully authenticated.
In some embodiments, the method further comprises:
and under the condition that the virtual domain to be accessed is judged to be illegal, or under the condition that the authentication result is authentication failure, managing the first ONU according to a standard mode.
The standard mode is associated with the PON system corresponding to the standard registration, and for example, when the standard registration is standard G/EPON registration, the standard mode may be a standard G/EPON management model. It is stated here that, in a case where it is determined that the virtual domain to be accessed is not legal, or in a case where the authentication result is authentication failure, the first ONU cannot be managed according to the management method provided in the embodiment of the present invention, but is managed according to a management mode of an existing PON system of a certain type, so as to achieve compatibility with a management model in the existing PON system.
S103: acquiring configuration information associated with the virtual domain to be accessed under the condition that the first ONU accesses the virtual domain to be accessed according to the access mode; and managing the first ONU based on the configuration information and the virtual domain to be accessed.
It is described herein that, after a first ONU accesses the virtual domain to be accessed, an OLT acquires configuration information associated with the virtual domain to be accessed, and instructs the virtual domain to be accessed to manage the first ONU based on the configuration information. Here, the configuration information acquired by the OLT may be already configured when the virtual to be accessed is created, or may be configuration updated during use, and either form may be stored in a memory or other database of the OLT and acquired when needed.
In an actual application process, the virtual domain to be accessed is indicated to manage the first ONU based on the configuration information, where the two different situations are: one is that the first ONU accesses the virtual domain to be accessed for the first time, and at this time, the first ONU needs to acquire all configurations of the virtual domain to be accessed to complete initialization configuration of the first ONU. In this case, the first ONU obtains the configuration information in a manner that the OLT issues the configuration information, that is, the configuration information is sent to the first ONU by the OLT.
As an implementation manner, in a case that the configuration information includes access sub-configuration information, the instructing, based on the configuration information, the virtual domain to be accessed to manage the first ONU includes: indicating the virtual domain to be accessed to complete the initialization configuration of the first ONU in the first subsystem; the initialization configuration is a matching process of the access sub-configuration information and the self-configuration information of the first ONU;
wherein the access sub-configuration information comprises at least one of: the identification information of the virtual domain to be accessed, the code of the member to be managed, the role of the member to be managed, the service model of the member to be managed, the Dynamic Bandwidth Allocation (DBA) mode of the virtual domain to be accessed and the networking mode of the virtual domain to be accessed; the self-configuration information includes: a first role; the initialization configuration includes at least one of: the method comprises the following steps of code configuration of the first ONU in the virtual domain to be accessed, service model configuration of the first ONU, DBA mode configuration of the first ONU and networking mode configuration of the first ONU.
It should be noted that the access sub-configuration information is all configurations of the aforementioned virtual domain to be accessed. The first role is a member role configured locally by the first ONU, and may also be understood as a role that a user expects the first ONU to need to assume in the first subsystem. And the first ONU completes initialization configuration based on the first role and the acquired configuration information containing the access sub-configuration information. Specifically, after receiving the configuration information including the access sub-configuration information, the first ONU automatically matches the code of the member to be managed in the configuration information including the access sub-configuration information according to the first role of the local configuration, and analyzes the Service model, networking mode, DBA mode of the virtual domain to be accessed, Quality of Service (QoS) mode of the virtual domain to be accessed, and the like corresponding to the first role, and automatically completes the local relevant configuration according to the analyzed information. The networking mode may be a MESH networking mode between the members in the to-be-accessed virtual domain.
Another is that after the first ONU completes the initialization configuration, the OLT updates the configuration in the virtual domain to be accessed, that is, when the configuration information may include updated sub-configuration information, the instructing, based on the configuration information, the virtual domain to be accessed to manage the first ONU includes: updating the initialization configuration of the first ONU based on the updating sub-configuration information indicating the virtual domain to be accessed.
It should be noted that, after the first ONU completes the initialization configuration, the subsequent OLT may update the configuration of the virtual domain to be accessed and the configurations of the members in the domain. In the process that the OLT manages all the virtual domains, when the OLT searches a certain virtual domain, the identity ID of the virtual domain is searched; the OLT may further perform related configuration on the virtual domain or update configuration on members in the virtual domain, specifically, the OLT may perform update configuration on the virtual domain, and specifically, updating the sub-configuration information may include: updating DBA mode, updating QOS mode and the like; the method can also be used for updating configuration of members in the virtual domain, and specifically, updating the sub-configuration information can include: the relevant update configuration of the ONU on the backbone node, specifically, the update sub-configuration information may be: channel open/close status, channel priority, channel bandwidth allocation, etc.; the updated configuration of the ONU on the end node may be: virtual Local Area Network (VLAN) in the second layer L2 (MAC layer) in the ISO Standard of the ONU, MAC update, update of the third layer L3 (Network layer) attribute (such as Internet Protocol (IP), ROUTE information) in the International Organization for standardization (ISO) Standard, and the like. After obtaining the configuration information containing the updated sub-configuration information, the OLT broadcasts to the ONUs in the virtual domain to be accessed so that the ONUs in the virtual domain to be accessed obtain the updated configuration information, and then the ONUs in the virtual domain to be accessed select corresponding configurations according to the obtained configuration information containing the updated sub-configuration information and the roles of the ONUs.
In some embodiments, the method further comprises:
performing heartbeat detection on the virtual domain to be accessed;
stopping performing heartbeat detection on the virtual domain to be accessed under the condition that the second ONU exits from the virtual domain to be accessed; converting the running state of the virtual domain to be accessed from an activated state to an idle state; and the second ONU exits from the last ONU accessing the virtual domain to be accessed.
It should be noted that the heartbeat detection performed on the virtual domain to be accessed may be heartbeat detection maintained between the OLT and the virtual domain to be accessed through the VCRP. And when the last entity ONU is off-line and the heartbeat is disconnected, the OLT resets the working state of the accessed virtual domain to an idle state. And judging how to quit the second ONU which is the last ONU accessing the virtual domain to be accessed. The specific mode can be as follows: the entity ONU is offline by the OLT according to the mechanism in the PON system where the ONU is located, when the OLT positions the role of the ONU, the change of the corresponding virtual domain can be sensed, thereby possibly triggering the OLT to send new configuration to other members of the virtual domain so as to ensure that the virtual domain service is not interrupted. However, for the purposes of the present invention: the virtual domain members can sense through heartbeat messages among the members, other members can sense necessarily when the ONU is off-line, and the main node in the virtual domain informs the OLT through the VCRP. When the OLT does not receive any heartbeat message from the member of the virtual domain, the virtual domain is considered to be offline, that is: the last ONU in the virtual domain exits.
The embodiment of the invention provides a management method of an optical network unit, under the condition of not changing the original hardware structure of an optical network communication system, a plurality of entity ONUs are indirectly managed by configuring a virtual domain, so that operations such as service configuration and the like are only needed to be carried out on the virtual domain, the virtual domain carries out management such as networking, service opening, service updating and the like on the accessed ONUs, and the ONUs do not need to be directly and independently managed, so that the configuration process of the ONUs is simplified, and the maintenance and the management are easy.
