Description

A method for provisioning zero-configuration services to optical fiber access terminal equipment

technical field

The invention relates to the technology of configuring optical fiber access terminal equipment (ONU/T) in a gigabit optical fiber access network (GPON), in particular to a method for issuing zero-configuration services to the ONU/T. the

Background technique

At present, the global backbone network has been fully fiber-optic, mainly using Dense Wavelength Division Multiplexing (DWDM) technology to increase network bandwidth, which can increase network bandwidth to 2.5 gigabits (G) to 10 gigabits per second (Gbps). Among them, the fiber optic growth rate of the metropolitan area network has increased rapidly, and the density is close to saturation, and the network bandwidth is 2.5G to 10Gbps; the network bandwidth of the local area network, such as Ethernet, has also increased from 100Mbps to 1Gbps for optical fiber transmission. From the perspective of the global overall network, only the network bandwidth of the access network between the metropolitan area network and the local area network is still in the digital subscriber line (DSL) level of millions, thus causing a bottleneck in the network bandwidth of the global overall network. the

In order to increase the network bandwidth of the access network and avoid becoming the network bandwidth bottleneck of the global overall network, the technology of using optical fiber to transmit data in the access network is proposed, that is, from the optical fiber access equipment (OLT) in the access network to The data transmission line between ONU/T adopts optical fiber. Among them, ONU/T can be placed on the roadside, in commercial and residential buildings, or even in the homes of residents. According to the different service modes distinguished by the distance from the optical fiber to the user, the optical fiber technology formed respectively is Fiber To The Curb (FTTC, Fiber To The Curb). Curb) technology, fiber to the building (FTTB, Fiber To The Building) technology and fiber to the home (FTTH, Fiber To The Home) technology, can also be collectively referred to as FTTx. the

The FTTC technology mainly serves the users in the residential area. The ONU/T is placed in the roadside box, and then the coaxial cable or twisted pair is drawn from the ONU/T to transmit data for the user. the

There are two types of FTTB technical services: the first is to serve users in apartment buildings, and the other is to serve companies in commercial buildings. These two service methods are to set the ONU/T at the basement distribution box of the apartment building or commercial building, but the ONU/T of the apartment building is an extension of the ONU/T in FTTC technology, while the commercial building is for the company. The network bandwidth must be increased to set the ONU/T. the

FTTH technology extends the distance of optical fibers to users' homes, so that users can be provided with higher network bandwidth. At present, the FTTH technology adopts the EPON mode of the point-to-multipoint (P2MP, Point to Mult-Point) architecture, as shown in Figure 1. This mode transmits the optical signal of the OLT downlink data through an optical fiber through an optical splitter passively. Devices (Splitter), broadcast to each ONU/T by category, greatly reducing the cost of establishing a network computer room and equipment maintenance for the OLT, and saving a lot of construction costs such as optical cable resources. the

The International Telecommunication Union (ITU) organization proposed the G.984.3 protocol in February 2004, proposing that the downlink network bandwidth supported in EPON applying FTTH technology is 1.24416 (gigabytes/second) Gbit/s or 2.48832Gbit/s , the supported uplink network bandwidth is 0.15552Gbit/s, 0.62208Gbit/s, 1.24416Gbit/s or 2.48832Gbit/s, and also proposed GPON transmission and convergence layer structure, message, distance correction scheme, operation management and maintenance (OAM) function and safety indicators. Fig. 2 adopts the protocol stack schematic diagram that prior art adopts EPON of FTTH technology to set up when transmitting data, including: asynchronous transfer mode client (ATM Client); ONU/T management and maintenance channel (OMCI); physical layer OAM ( PLOAM), used to provide EPON management functions such as ranging, activating ONU/T, issuing OMCC and alarm transmission; GPON encapsulation method client (GPON Client); GPON transmission aggregation layer (GPON Transmission); OMCI adaptation layer ( OMCI adapter); ATM transmission aggregation adaptation layer (ATM TC); GEM encapsulation transmission aggregation adaptation layer (GEM TC), dynamic bandwidth allocation control (DBA Control); GPON transmission aggregation frame sublayer (GTC) and GPON media physical layer (GPON layer). the

Before OLT and ONU/T transmit data or before ONU/T accesses the Internet to transmit data through OLT, ONU/T needs to be configured to establish a basic traffic channel between OLT and ONU/T, that is, to establish OMCI and data channels, among which OMCI is used to manage and control ONU/T, and the data channel is used to provide ONU/T to transmit data. At present, the process of configuring the ONU/T is: manually configure the ONU/T at the place where the OLT is placed and each ONU/T place connected to the OLT, and configure the basic traffic channel between the two. It can connect 1 to 64 ONU/T, or even more, so if you go to each ONU/T connected to the OLT and configure each ONU/T and OLT manually, the configuration will be cumbersome and the workload will be heavy. ; And configuration costs are high.

Contents of the invention

In view of this, the main purpose of the present invention is to provide a method for ONU/T zero-configuration service distribution, which avoids the disadvantages of cumbersome process, heavy workload and high cost for ONU/T configuration of basic traffic channels. the

According to above-mentioned purpose, technical scheme of the present invention is achieved like this:

A method for distributing zero-configuration services to optical fiber access terminal equipment ONU/T, configuring the functions of discovering ONU/T and negotiation stipulated in the G.984.3 protocol in the optical fiber access equipment OLT, the method comprising:

A. After the OLT discovers the ONU/T, it negotiates to establish a physical layer maintenance PLOAM channel between the two;

B, OLT sends to ONU/T by PLOAM channel the extended PLOAM message that carries the configuration information that establishes ONU/T management and maintenance channel OMCI and the configuration information that establishs data channel; Described establishment OMCI configuration information is: the ONU of ONU/T Identify the ONU-ID, establish the virtual transmission container TCONT identification of OMCI and the port identification PORT-ID, wherein, there is a one-to-one correspondence between the TCONT identification and the PORT-ID; the configuration information for establishing the data channel is the ONU-ID, the establishment of the data channel The TCONT logo and PORT-ID, where there is a one-to-one correspondence between the TCONT logo and PORT-ID;

C. The ONU/T that receives the extended PLOAM message establishes the OMCI with the OLT according to the configuration information of the carried OMCI, and establishes the data channel with the OLT according to the configuration information of the carried data channel. the

The configuration information of the OMCI and the configuration information of establishing a data channel are respectively carried in two extended PLOAM messages and sent to the ONU/T. the

After step C, the method also includes: the ONU/T sends a confirmation message of the extended PLOAM message to the OLT through the PLOAM channel, confirming that the OMCI and the data channel have been established, and the data is transmitted between the OLT and the ONU/T through the established data channel , OLT maintains and manages ONU/T through OMCI. the

The confirmation message of the extended PLOAM message is respectively the confirmation message of the PLOAM message carrying the configuration information of establishing OMCI and the confirmation message of the PLOAM message carrying the configuration information of establishing the data channel. the

The configuration information for establishing the OMCI is carried in the flow management message GEM Stream message in the extended PLOAM message and sent to the ONU/T. the

The configuration information for establishing the data channel also includes the identification VLAN-ID of the virtual local area network for establishing the data channel, TCONT type and QOS level of business service quality. the

Before OLT sends the PLOAM message that carries VLAN-ID, TCONT type and QOS grade, this method also includes:

The ONU/T accesses the server in the external network via the OLT through the established data channel, and the server sends the VLAN-ID, TCONT type and QOS level of the data channel to be obtained by the ONU/T to the OLT. the

When there are multiple data links in the established data channel, the configuration information of the established data channel also includes the total number of established data link information and the serial number of the established data link information. the

The configuration information for establishing the data channel is carried in the GEM Streammessage in the extended PLOAM message and sent to the ONU/T. the

The method also includes the process of setting the ONU/T for the upstream flow bandwidth of the data channel:

The OLT sends the upstream traffic bandwidth information of the data channel to the ONU/T by using the extended PLOAM message through the PLOAM channel;

The ONU/T sets the upstream traffic bandwidth for the data channel according to the upstream traffic bandwidth information in the received extended PLOAM message. the

The uplink traffic bandwidth information includes uplink peak traffic and uplink average traffic. the

The extended PLOAM message also carries the ONU-ID of the ONU/T, and the ONU/T determines the data channel according to the received ONU-ID in the PLOAM message. the

The upstream traffic bandwidth information carried in the extended PLOAM message is sent to the ONU/T in the upstream traffic bandwidth message PORD-ID CAR message. the

As can be seen from the above scheme, the present invention is to carry out the establishment of the basic flow channel of the ONU/T by the OLT, rather than manually going to the placement of each ONU/T to carry out the establishment of the basic flow channel of the ONU/T, so the OLT can be realized For the distribution of zero-configuration services for multiple ONU/Ts, it is not necessary to invest a lot of manpower and material resources to configure each ONU/T one by one. Therefore, the method provided by the present invention avoids the disadvantages of cumbersome process, heavy workload and high cost for configuring the basic traffic channel for the ONU/T. the

Detailed ways

In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail by giving specific embodiments and referring to the accompanying drawings. the

The present invention adopts the OLT to configure the connected ONU/T, which is also called zero-configuration service distribution. the

Fig. 3 is that OLT of the present invention carries out the distribution method flowchart of zero-configuration service to ONU/T, and its specific steps are:

Step 300, configuring the ONU/T discovery and negotiation functions stipulated in the G.984.3 protocol in the OLT. After the OLT discovers the connected ONU/T, it uses the negotiation function to establish a PLOAM channel. the

When the ONU/T connected to the OLT is powered on, the OLT can use the discovery mechanism stipulated in the G.984.3 protocol to discover the ONU/T, and negotiate with the discovered ONU/T to establish a PLOAM channel. This step can be implemented in the manner described in the prior art. the

Step 301, the OLT sends a PLOAM message to the ONU/T through the established PLOAM channel, and the message carries the ONU/T identification (ONU-ID) set for the ONU/T and configuration information for respectively establishing OMCI and data channels. the

Wherein, the configuration information used to respectively establish OMCI and data channels may be a virtual transport container (TCONT) identifier or/and a port identifier (PORT-ID), and there is a one-to-one correspondence between the TCONT identifier and PORT-ID identifying OMCI There is a one-to-one correspondence between the TCONT identifier of the data channel and the PORT-ID. the

In the present invention, a virtual local area network identifier (VLAN-ID) may also be used as configuration information for establishing a data channel. the

Step 302, after ONU/T receives the PLOAM message through the PLOAM channel of establishment, set up according to the ONU-ID carried, the configuration information that is used to set up OMCI and data channel respectively, set up the OMCI and the OMCI with ONU-ID between OLT For the data channel, the established OMCI and the data channel are respectively identified by the configuration information carried in the PLOAM message. the

In the established data channel, the present invention can have more than one data link, at this moment, can also send the configuration information of data link to ONU/T respectively by PLOAM message, by ONU/T according to the configuration information of data link The configuration information configures the data link. the

In step 303, the ONU/T sends a confirmation message of the PLOAM message to the OLT through the PLOAM channel, so that data can be transmitted between the OLT and the ONU/T. the

In the present invention, the confirmation message of the PLOAM message may not be sent, but the data transmission between the OLT and the ONU/T can be started directly. the

In the present invention, the configuration information used to set up OMCI and the configuration information used to set up data channels can be sent sequentially using PLOAM messages respectively. After receiving the configuration information used to set up OMCI and configuring OMCI, the ONU/T sends The OLT sends the confirmation message of the PLOAM message carrying the configuration information used to establish the OMCI; after the ONU/T receives the configuration information used to establish the data channel and configures the data channel, it sends the PLOAM message carrying the configuration information of the user to establish the data channel to the OLT The acknowledgment message for the message. the

In Fig. 3, the upstream traffic bandwidth of the data channel set up between OLT and ONU/T adopts default setting, promptly is set to the upstream traffic bandwidth of ONU/T default. In practical application, the OLT may send the upstream traffic bandwidth information of the data channel to the ONU/T through the PLOAM channel by using the PLOAM message, including the upstream peak traffic and the upstream average traffic. Of course, the PLOAM message also carries information for identifying the data channel. When the ONU/T receives the PLOAM message through the PLOAM channel, it determines the data channel and the upstream traffic bandwidth used by the data channel according to the carried information. When the data channel sends data, the determined uplink traffic bandwidth is used to send data. In the present invention, the information used to identify the data channel is the ONU-ID of the ONU/T. After the ONU/T determines the data channel and the upstream traffic bandwidth used by the data channel, it can also send a confirmation message of the PLOAM message to the OLT through the PLOAM channel, so that the OLT can determine that the ONU/T has executed the message sent to the PLOAM. the

After the OLT and ONU/T establish the OMCI and data channel, ONU/T can access the external network through the OLT, such as the Internet. Since the configuration of the ONU/T by the OLT is only the configuration of some basic services, such as the configuration of ONU-ID, TCONT identification, PORT-ID and TCONT type, etc., it can only meet the configuration of the ONU/T that supports Layer 2 services. If the ONU/ T supports the three-layer service, then needs ONU/T adopts the TR069 mode of prior art to get configuration information on the server of external network through OLT and configures, as the priority of data channel and the virtual local area network identification (VLAN-ID) of data channel ) configuration, etc. When the ONU/T transmits data or obtains configuration through the OLT, the bandwidth of the data channel can be configured on the OLT, that is, the default bandwidth setting of the data channel is set through the existing dynamic bandwidth allocation (DBA) of G.984.3. the

In order to realize the distribution method of the zero-configuration service of the OLT to the ONU/T, the present invention needs to expand the PLOAM message so that it can carry the ONU-ID and the configuration information used to set up the OMCI and the data channel respectively; it can also be used to carry the information of the data channel Uplink traffic bandwidth information. The extended PLOAM message will be described in detail below. the

In the PLOAM message, a flow management message (GEM Stream message) is extended and added, and its message identification (message-ID) is 241; in the PLOAM message, an upstream flow bandwidth message (PORD-ID CAR message) is also extended, and its message- The ID is 242. When the OLT issues the zero-configuration service to the ONU/T, these two messages can be sent repeatedly for many times. the

Table 1 describes the two messages. Message ID message name effect Triggering conditions take up time receive response 241 GEM Stream message Activate or deactivate OMCI or data channel When the OLT sets or disconnects an ONU/T 3 Send an acknowledgment message after a message has been successfully received 242 PORT-ID CAR message Limit the bandwidth of ONU/T upstream traffic When OLT is set with ONU/T 3 ONU/T sets the upstream traffic bandwidth of the data channel, and sends a confirmation message after successfully receiving the message

The following two specific examples are given to illustrate the present invention. the

Fig. 4 is a schematic diagram of OLT carrying out zero-configuration service distribution embodiment one to ONU/T, as shown in the figure: ONT is provided with the data path of the OMCI that is marked as TCONT0 and the default upstream traffic bandwidth of TCONT1 for ONU/T. The OMCI identified by TCONT0 can also be identified by PORT-ID0. OMCI is used to maintain and manage ONU/T; the data channel of the default upstream traffic bandwidth identified by TCONT1 can also be identified by PORT-ID1. This data channel is used for ONU/T Data transmission through multiple Fiber Edge (FE) ports. The information used to identify the two channels is sent to the ONU/T through the PLOAM message, which is shown as an ONU/T with FE ports in the figure, and each FE port can configure a data link in the data channel. In the present embodiment, VLAN-ID and QOS are not provided, default is 0, and when ONU-ID adopts ONU/T power-on, ONT is the ONU-ID that ONU/T distributes automatically according to existing G.984.3 agreement. the

table 5

Among them, since Table 4 is used to set OMCI, it is necessary to ensure that the TCONT type is 1 (specified in the G.984.3 protocol); Table 5 is used to set the data channel of the default traffic bandwidth, so the TCONT type is 5 (specified in the G.984.3 protocol of). the

Fig. 5 is the method flow chart of OLT carrying out zero-configuration service issuing embodiment one to ONU/T, and its specific steps are:

Step 500, OLT sends the GEM Stream message described in Table 4 to ONU/T. the

Step 501, after the ONU/T establishes the OMCI identified by TCONT0 according to the configuration information carried by the received GEM Stream message, it sends a confirmation message of the GEM Stream message to the OLT. the

Step 502, OLT sends the GEM Stream message described in Table 5 to ONU/T. the

Step 503: After the ONU/T establishes a data channel identified by TCONT1 according to the configuration information carried by the received GEM Stream message, it sends a confirmation message of the GEM Stream message to the OLT. the

In step 504, data can be transmitted between the OLT and the ONU/T through the established data channel, and can be maintained and managed through the established OMCI. the

Figure 6 is a schematic diagram of the second embodiment of OLT issuing zero-configuration services to ONU/T, as shown in the figure: ONU/T is connected to three devices, which are home gateway (HomeGateway), video on demand (VOD) and IAD. Among them, HomeGateway needs to use the data channel with the default traffic bandwidth established between ONU/T and OLT, that is, the data channel identified by TCONT1 to transmit data; VOD needs to use the data channel established between ONU/T and OLT identified by TCONT2 Data transmission; the IAD needs to use the data channel with two data links identified by TCONT3 established between the ONU/T and the OLT to transmit data. At this time, when the ONU/T connected with these three devices is powered on and discovered by the OLT, the OLT first establishes the OMCI identified by TCONT0 and the data channel identified by TCONT1 between the ONU/T through the PLOAM message; and then through the PLOAM Data channels marked by TCONT2 and TCONT3 are established between the message and the ONU/T. It is worth noting that after the data channels marked by TCONT2 and TCONT3 are established between the OLT and the ONU/T, VOD and IAD cannot use these two data channels respectively, but can only use the data channel marked by TCONT1. The reason is that the ONU/T does not configure any parameters of the two data channels, and the ONU/T cannot read the VLAN-ID and QOS of the two data channels. Therefore, in order to enable VOD and IAD to use these two data channels respectively, ONU/T uses TR069 to register with the server of the external network through the OLT, and obtains the configuration information of the two data channels through the OLT, including VLAN-ID, priority and other three-layer configuration information (the configuration information is still sent to the ONU/T through the PLOAM message), after the ONU/T obtains the configuration information of these two data channels and configures them, VOD and IAD can use these two data channels channel up. the

Taking VOD as an example, Table 6 shows the specific description of the Configure GEM Stream message in the PLOAM message used when establishing the data channel identified by TCONT2, where the TCONT identification carried by the message is 2, the TCONT type is 2, and the PORT-ID is 2.
