Description

Passive optical network traffic flow configuration

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for configuring a passive optical network service flow.

Background

A typical passive optical network (Passive Optical Network, PON) is mainly composed of three parts, an optical line terminal (Optical Line Terminal, OLT), an optical network unit (Optical Network Unit, ONU), and an optical distribution network (Optical Distribution Network, ODN).

The OLT is generally placed in a Central Office (Central Office), and is a core device of an entire GPON (Gigabit-Capable PON) system. The OLT is typically an ethernet switch, router or multimedia conversion platform that provides the interface between the GPON system and the service provider's core data/video/telephony network.

The ONU is used for connecting network devices (such as a PC, a set-top box, and an exchange) on the user side, and is usually placed in a user's home, corridor, or roadside, and is mainly responsible for forwarding uplink data (packets sent by the ONU to the OLT) on the user side and selectively receiving downlink broadcast data (packets sent by the OLT to the ONU) forwarded from the OLT side.

The ODN is composed of an optical fiber and one or more passive optical devices such as passive optical splitters (Passive Optical Splitter, POS) and provides an optical signal transmission channel between the OLT and the ONU. The POS may couple upstream data onto one fiber and distribute downstream data to individual ONUs.

The GPON encapsulation mode Port (GPON Encapsulation Method Port, GEM Port) is a virtual Port on the OLT and the ONU, and the OLT and the ONU establish a virtual channel through the GEM Port, and service data is transmitted between the OLT and the ONU through the virtual channel.

The transport container (Transmission CONT, T-CONT) is a concept introduced in GPON dynamic allocation techniques for improving the efficiency of dynamic allocation. GPON supports multiple T-CONT types, and different types of T-CONT have different types of bandwidths, so that services with different service qualities can be supported. The T-CONT type includes a fixed bandwidth type, a guaranteed bandwidth type, a burst allocation type having a minimum guaranteed bandwidth, a best effort allocation type, and a combined allocation type.

The GPON network is divided into virtual connection by the GEM Port and the T-CONT, so that service multiplexing is realized, and one GEM Port can bear one service and can bear multiple services. And mapping the GEM Port bearing service to the T-CONT unit to perform uplink service scheduling. Each ONU supports multiple T-CONTs and may be configured for different traffic types.

One T-CONT may carry multiple GEM ports, or may carry one GEM Port, depending on the specific configuration of the user. And the T-CONT uplink to the OLT side demodulates the GEM Port, then demodulates the service payload in the GEM Port, and carries out relevant service processing.

In the downstream direction (OLT to ONU), all traffic flows are GEM Port encapsulated in a GPON traffic processing unit and then broadcast to all ONUs under the GPON interface. And the ONU performs data filtering according to the GEM Port identification, only retains the data of the GEM Port belonging to the ONU, and sends the service data into the user equipment from the service interface of the ONU after decapsulation.

In the upstream direction (ONU to OLT), various services are mapped to different GEM ports on the ONU, and then data in the GEM ports are mapped to different types of T-CONT for upstream transmission to the OLT. The T-CONT demodulates the GEM Port unit at the OLT side, sends the GEM Port unit into the GPON MAC chip to demodulate the service data in the GEM Port payload, and sends the service data into the relevant service processing unit for processing.

The GEM Port ID is a unique identifier of the GEM Port, the ONU identifies data belonging to the ONU according to the GEM Port ID, the payload part of the GPON downlink frame contains a plurality of GEM frames, and the needle head part of the GEM frames carries the GEM Port ID and is used for identifying the data belonging to each ONU; ALLOC ID is used for identifying T-CONT, and is carried in BW MAP field of frame head of GPON downlink frame, and is used for distributing start-stop time slot of transmitting data from T-CONT of next ONU to OLT.

To realize service traffic intercommunication between the OLT device and the ONU device, a GEM Port ID and a T-CONT corresponding to the service need to be configured for each ONU device on the OLT device, a virtual service flow channel interface (referred to as a service flow virtual interface for short) is configured, and the service flow is managed through the service flow virtual interface.

In the prior art, in the process of configuring a service flow channel between an OLT device and an ONU device, a GEM Port and a T-CONT are required to be established first, the GEM Port and the T-CONT are bound, then a virtual interface is established for the service flow channel, and finally the GEM Port and the established virtual interface are bound.

The above process of configuring a traffic channel between OLT equipment and ONU equipment has several drawbacks:

(1) In addition, the binding of the GEM Port and the T-CONT needs to be configured, a large amount of configuration maintenance work is needed, and the difficulty and complexity of opening and operation and maintenance are improved.

(2) The corresponding relation between the created service virtual interface and the specific ONU is not clear, and the difficulty and complexity of searching and maintaining are increased.

(3) The binding operation of the virtual interface and the GEM Port increases operation steps, the corresponding relation between the virtual interface and the GEM Port needs to be manually involved in configuration binding, and the difficulty and complexity of searching and maintenance are increased.

The invention provides a service flow configuration scheme in a passive optical network for reducing the configuration and operation and maintenance difficulty of a service flow channel between an OLT device and an ONU device and improving the switching and operation and maintenance efficiency. The invention can hide the related configuration of GEM Port in the GPON technology in the OLT equipment configuration operation and maintenance, and realize the association of the service flow configuration and the ONU, thereby reducing the management maintenance difficulty and complexity of the passive optical network and improving the management maintenance efficiency.

Based on the basic idea of the invention, it is to be explained that the steps shown in the flowcharts of the figures can be performed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases the steps shown or described can be performed in an order different from that here.

Fig. 1 is a schematic diagram of a networking structure of a GPON passive optical network according to an embodiment of the present invention. In the example GPON network of fig. 1, the configuration of the virtual traffic channel interface (abbreviated as traffic virtual interface) is performed at the OLT device, and after the OLT device receives the configuration through the configuration interface, the OLT device issues the configuration to the ONUs 1 to ONUn through the optical distribution network ODN. The network manager issues configuration of ONU subinterfaces to the OLT equipment or issues service flow configuration on the ONU subinterfaces in a command line mode through the network management system, the ONU subinterfaces replace service flow virtual interfaces in the original GPON protocol, and a configuration module on the OLT equipment can automatically allocate and associate GEM ports for the ONU subinterfaces and automatically bind the associated GEM ports to T-CONT bound by the ONU subinterfaces. The network manager does not need to manually perform GEM Port configuration, GEM Port and T-CONT binding configuration and GEM Port binding configuration of the service flow virtual interface.

Fig. 2 is a schematic diagram of a binding relationship between an ONU subinterface and a traffic flow virtual interface in a GPON passive optical network according to an embodiment of the present invention. In the example of fig. 2, the ONU subinterface identifier includes three parts of identifier information including an OLT port identifier, an ONU device identifier, and a subinterface number, where:

the generation rule of the OLT port identification is as follows: "frame number/slot number/port number". As in the example of fig. 2, the OLT port identification "OLT 3/2/3" represents the 3 rd port with the OLT device port located in the 2 nd slot of the 3 rd subrack;

the generation rule of the ONU equipment identifier is as follows: "OLT port identification" + ": "+" ONU identification. As in the example of fig. 2, the ONU device identifier "ONU 3/2/3:1" represents that the ONU device is the 1 st ONU under the OLT device port identified by "OLT 3/2/3", and if the 2 nd ONU is further suspended under the "OLT 3/2/3" port, the ONU device identifier is "ONU 3/2/3:2", and so on.

The generation rule of the ONU sub-interface identification is as follows: "ONU device identification" + "+" subinterface number. As in the example of fig. 2, the ONU subinterface identifier "ONU3/2/3:1.1" represents the 1 st subinterface of the 1 st ONU under the port of the OLT device identified by "OLT 3/2/3", and if the ONU device includes multiple subinterfaces, the word interfaces are numbered sequentially, and the ONU subinterface identifier "ONU3/2/3:1.2" represents the 2 nd word interface on the ONU device.

In the embodiment of the invention, the relevant configuration (abbreviated as service flow configuration) of the virtual service flow channel is directly issued to the ONU sub-interfaces, one ONU sub-interface corresponds to the GEM Port of one service flow channel, the T-CONT required by the service flow is bound on the ONU sub-interface, the configuration module on the OLT equipment can automatically bind the GEM Port associated with the ONU sub-interface to the T-CONT, and the operation and maintenance manager cannot sense the existence of the GEM Port. As in the example of fig. 2, multiple ONU subinterfaces "ONU3/2/3:1.1", "ONU3/2/3:1.2", …, "ONU 3/2/3:1.x" are bound to the same T-CONT, and OLT apparatus will automatically bind GEM ports associated with these ONU subinterfaces to the T-CONT. Different ONU subinterfaces on the same ONU device may be bound with traffic flows of different traffic types, for example, a bound voice traffic flow is configured for an "ONU3/2/3:1.1" subinterface, a bound internet traffic flow is configured for an "ONU3/2/3:1.2" subinterface, etc.

The invention shields the configuration of GEM Port, replaces the original business flow virtual interface with the ONU sub-interface, and enables the business flow configuration to be directly related with the ONU sub-interface, thereby realizing the correspondence between the business flow configuration and the ONU, and further simplifying the operation and management of the GPON network.

Fig. 3 is a schematic flow chart of steps of a service flow configuration method in a GPON optical network according to an embodiment of the present invention, where the method is applied to an OLT device, and a configuration interface in the drawing may be a command line configuration interface on the OLT device, or may be a WEB configuration interface of a network management system, that is, an operation and maintenance manager may directly issue configuration on the OLT device in a command line manner, or may issue the configuration to the OLT through the WEB configuration interface, and after receiving the configuration issued by the command line or issued by the network, the OLT device issues the configuration to a configuration module, where the configuration is issued to an OLT port and an ONU device associated with the OLT port by the configuration module according to the following steps. The method comprises the following steps:

s301, based on a configuration request issued by a configuration interface, creating a T-CONT and issuing the T-CONT to be configured to ONU equipment;

when the OLT equipment receives a configuration request for creating the T-CONT through the configuration interface, the corresponding T-CONT is created, and then the T-CONT configuration is issued to the ONU equipment so that the ONU equipment generates relevant configuration.

The transmission container T-CONT is related to the service quality requirement of the service flow, the GPON supports a plurality of T-CONT types, and different types of T-CONTs have different types of bandwidths and can support the services with different service qualities.

In the GPON network, the traffic flow from the ONU to the OLT in the upstream direction is mapped into the T-CONT bound by the ONU subinterface, and is transmitted to the OLT device in the upstream direction. After the OLT equipment receives the T-CONT, demodulating a GEM Port encapsulated data unit associated with the ONU subinterface from the T-CONT, sending the data unit to a MAC chip of the GPON, demodulating service data in the payload of the GEM Port data unit, and sending the service data to a relevant service processing unit for processing.

S302, creating an ONU sub-interface based on a configuration request issued by a configuration interface, automatically distributing and associating GEM Port identifiers for the ONU sub-interface, and issuing configuration information related to the ONU sub-interface and the associated GEM Port to ONU equipment;

after the OLT equipment receives a configuration request for creating the ONU sub-interface through the configuration interface, the corresponding ONU sub-interface is created, and a configuration module of the OLT equipment automatically distributes a GEM Port identifier for the created ONU sub-interface, so that the association relation between the ONU sub-interface and the GEM Port is established. The OLT device may issue configuration information related to the ONU subinterface and the associated GEM Port to the ONU device, so that the ONU device generates a corresponding configuration.

In an alternative embodiment of the present invention, the OLT apparatus configuration module allocates GME Port identifiers to ONU subinterfaces in a dynamic allocation manner, where the dynamic allocation manner uses a currently idle unused GME Port identifier as a resource pool, and extracts a currently idle unused GME Port identifier from the resource pool to allocate to a newly created ONU subinterface when creating a new ONU subinterface.

In an alternative embodiment of the present invention, the OLT device configuration module allocates GME Port identifiers for ONU subinterfaces in a static allocation manner, that is, allocates a GME Port identifier space (formed by a plurality of consecutive GME Port identifiers) in advance for each ONU device, and when creating an ONU subinterface, automatically allocates and associates a GME Port identifier for the created ONU subinterface, which is the GME Port identifier space base address plus the ONU subinterface number offset (that is, the value of the subinterface number-subinterface start number allocated for the newly created ONU subinterface). For example, assuming that the GME Port identification space pre-allocated for the ONU device "ONU 3/2/3:1" is "300-309", the ONU device can create 10 subinterfaces at most, when creating the subinterface "ONU3/2/3:1.1" for the ONU, the GME Port identification automatically allocated and associated for the ONU subinterface is GME Port identification space base 300+ subinterface number 1-subinterface start number 1=300.

S303, binding a required T-CONT on the created ONU subinterface based on a configuration request issued by the configuration interface, and automatically binding a GEM Port identifier associated with the ONU subinterface with the required T-CONT;

after the OLT equipment receives the ONU subinterface and the T-CONT binding configuration request through the configuration interface, the required T-CONT is bound on the created ONU subinterface according to configuration information (ONU subinterface identification, T-CONT identification and the like) carried by the configuration request, the association relation between the ONU subinterface and the GEM Port is stored in a configuration module of the OLT equipment, and the configuration module of the OLT equipment automatically binds the GEM Port identification associated with the ONU subinterface with the required T-CONT.

S304, after receiving the service flow configuration request, carrying out service flow configuration on the ONU subinterface and automatically binding GEM ports associated with the ONU subinterface with the service flow configured on the ONU subinterface.

After receiving the service flow configuration request, the OLT device performs service flow configuration on the ONU subinterfaces according to the ONU subinterface identifiers and the service flow configuration information carried in the configuration request, where the service flow configuration includes, but is not limited to, configuration of a virtual local area network VLAN, quality of service Qos configuration, access control list ACL configuration, and the like.

The invention uses ONU sub-interface to replace the business flow virtual interface in the prior art, and the expression is to use the ONU sub-interface as the original business flow virtual interface, to carry out business flow configuration on the ONU sub-interface, and the OLT equipment automatically binds the GEM Port associated with the ONU sub-interface with the business flow configured under the ONU sub-interface.

By the service flow configuration method, operation and maintenance managers can not sense the existence of GEM ports and only need to maintain the direct binding relation between ONU subinterfaces and service flows, thereby reducing the operation and maintenance management difficulty of the whole GPON network and improving the efficiency of the operation of the GPON optical network.

The passive optical network described in the present invention includes, but is not limited to, GPON, XGPON,50GPON.
