Description

GPON ONU service deployment method and device

Technical Field

The invention relates to the technical field of communication, in particular to a GPON ONU service deployment method and device.

Background

The GPON (Gigabit-Capable Passive Optical network) technology is a latest generation broadband Passive Optical integrated access standard based on ITU-t g.984.x standard, and has the advantages of high bandwidth, high efficiency, large coverage area, rich user interfaces, and the like, so that the GPON technology is widely applied to service bearing of an access network, and can support service types such as data, voice, video, and the like.

In order to facilitate unified management, the GPON protocol standard abstracts various resources and functions on an ONU (Optical Network Unit) into an ME (Managed Entity), and the ONU needs to obtain a complete ME configuration when opening a service. In general, an OLT often has a large number of ONUs, and either operation and maintenance personnel complete ME provisioning of hundreds of ONUs when opening an office, or customer service personnel complete ME provisioning of ONUs one by one when installing ONUs in an installation master. For this reason, from the perspective of the OLT, it is necessary to provide a more intelligent GPON ONU deployment scheme, so that the opening process is simpler.

In order to solve the above problems, in the prior art, an OLT (Optical Line Terminal) issues a service model to an ONU, which describes the complete ME configuration of the ONU and the reference relationship between MEs. However, the service model has a certain dependence on the ONU capability information, and the ONUs of different manufacturers and different models have different capabilities, and when a service is opened, the OLT needs to manually deploy the service models of different ONUs one by one, which leads to slow opening and complex operation.

In order to facilitate understanding of the technical solutions provided by the embodiments of the present invention, the basic concepts related to the solutions are briefly explained.

Each mapping mode is selectable, and at least 1 mapping mode is usually selected in practical application;

UNI (User Network Interface) side: an ETH PORT (Ethernet Port ) ME is an abstraction of a UNI side Ethernet service PORT in a GPON service model of a two-layer device; the ME (virtual Ethernet Interface Point) port is the abstraction of all Ethernet service ports at UNI side in the GPON service model of the three-layer equipment; the IP HOST (Internet protocol HOST) protocol stack ME is an abstraction of the UNI side IP service port in the GPON service model; in practice, an ONU may have transmission for at least 1 service among them according to its capability;

If the ONU bears 1 service, the service model is generated according to the public submodel template and the personalized submodel template of the service; if the ONU bears 2 services, the service model is generated according to the public sub-model template, the personalized sub-model template of the 1 st service and the personalized sub-model template of the 2 nd service; if the ONU bears 3 services, the service model is generated according to the public sub-model template, the personalized sub-model template of the 1 st service, the personalized sub-model template of the 2 nd service and the personalized sub-model template of the 3 rd service. And so on. In the embodiment of the invention, each sub-model template describes different types of ME related to ONU and the association relation thereof, when a public sub-model template and a personalized sub-model template are generated, only a service model formed by the sub-model templates can meet the basic transmission requirement of a user on service, and the specific generation process can be that the service model is stored on the OLT in a data description mode after being designed in advance by technical personnel.

In this step 203, after the OLT acquires the service carrying capacity information of the ONU, the common sub-model template and the corresponding personalized sub-model template are instantiated according to the acquired information in combination with the configuration template information to obtain each sub-model. In the embodiment of the invention, the ME in each sub-model has the own ME ID and the function attribute information. The specific sub-model generation process is as follows.

(1) When the number of the collected ETH ports is more than 0

And the OLT reads the ONU board card management information and generates a board card level management sub-model of an ETH port type. In this step, the slot ME and the board ME in the sub-model are created in advance by the ONU, and are acquired when the OLT acquires the service carrying capability information from the ONU. The slot ME and the board ME do not include an ETH port ME, but the related attributes thereof indicate how many ETH ports are theoretically supported by the board of the type, how many ETH ports are actually supported, and other slot management related attributes.

And the OLT generates an ETH sub-model of each ETH port and a corresponding MAC bridge sub-model according to the acquired ETH port information, the two-layer Ethernet service port sub-model template and the MAC bridge sub-model template, wherein the functional attribute configuration of each ME in each sub-model is acquired from the configuration template information, and the other ME IDs except the acquired ME ID are acquired from the configuration template information. Specifically, each acquired ETH port has its own ETH submodel and corresponding MAC bridge submodel, and the generation process may specifically include:

The N1 ETH submodels are identical in functional attribute configuration except for the differences in ME IDs. Wherein N1 is the number N1 of ETH ports of the ONU that is acquired. Similarly, the generation manner of the MAC bridge submodels corresponding to the N1 ETH ports is similar, and details are not repeated herein, and except that the ME IDs of the N1 MAC bridge submodels are different, the remaining functional attribute configurations are the same.

And if the number of the acquired ETH ports is 0, not triggering the step (1) when the number of the ETH ports is more than 0.

(2) When the number of the collected VEIP ports is more than 0

And the OLT reads the ONU board card management information and generates a board card level management sub-model of the VEIP port type. In this step, the slot ME and the board ME in the sub-model are created in advance by the ONU, and are acquired when the OLT acquires the service carrying capability information from the ONU. The slot ME and the board ME do not include the VEIP port ME, but relevant attributes thereof indicate how many VEIP ports are theoretically supported by the board of the type, how many VEIP ports are actually supported, and other attributes relevant to slot management.

And the OLT generates a VEIP submodel of each collected VEIP port and a corresponding MAC bridge submodel according to the collected VEIP port information, the VEIP three-layer virtual Ethernet service port submodel template and the MAC bridge submodel template, wherein the functional attribute configuration of each ME in each submodel is obtained from the configuration template information, and the other ME IDs except the collected ME ID are obtained from the configuration template information. Specifically, each collected VEIP port has its own VEIP submodel and corresponding MAC bridge submodel, and the generation process may specifically include:

for each collected VEIP port:

In this step, the slot ME and the board ME in the sub-model are created in advance by the ONU, and are acquired when the OLT acquires the service carrying capability information from the ONU. The slot ME and the board ME do not include a POTS port ME, but their associated attributes indicate how many POTS ports are theoretically supported by the board of this type, how many POTS ports are actually supported, and other slot management-related attributes.

The mapping relation between the GEM PORT ME and the MAC bridge ME is determined by the ME configuration of a service mapping mode corresponding to the GEM PORT ME: when mapping VLAN or priority, GEM PORT ME needs to be associated with each obtained MAC bridge ME; when the PORTs are mapped, the GEM PORT ME only needs to be configured according to the corresponding mapping mode ME, and the MAC bridge ME corresponding to the corresponding service PORT is associated. Here, the corresponding service port is a specific port under a specific service, and is determined by mapping ME configuration.

And step 204, the collected public sub-models and all the collected personalized sub-models are used as the service models of the ONU, and the service models are issued to the ONU according to the issuing sequence between the MEs required by the GPON protocol.

Example two

In this embodiment, on the basis of the first embodiment, a method for calculating a part of the ME ID in the service model of the ONU is further defined.

The GPON ONU service deployment method provided in the embodiment of the present invention further includes determining an ME identifier ID in the service model of the ONU, in addition to step 200 and step 204. The OLT refers to fig. 10 for the correspondence between the MAC bridge ME and its ME on the ANI and UNI sides. Illustratively, the determining process specifically includes:

the identification ID (i, j) of the MAC bridge ME is: ID (i, j) ═ j, where i is 1; ID (i, j) is ID (i-1, S)_i-1) + j, where i>1，S_i-1Number of service ports, ID (i-1, S), for the i-1 st service_i-1) Is the S th service under the i-1 th service_i-1MA in MAC bridge submodel corresponding to each service portIdentification of the ME bridge;

in the MAC bridge submodel corresponding to the jth service PORT under the ith service, the number of the PORT connected to the related MAC bridge in the ME attribute of the MAC bridge PORT corresponding to the pth GEM PORT is p; the port number connected to the associated MAC bridge in the ME attribute of the MAC bridge port in the sub-model of the jth service port under the ith service is as follows: p + j, wherein P is the number of GEM PORT MEs. In this step, the lower case "P" and the upper case "P" respectively represent different physical meanings, the former referring to the number of the GEM PORT ME, and the latter referring to the total number of all GEM PORTs. Of course, any other two different alphabetic characters may be used to uniquely identify the two different physical meanings.

The following examples are given. Assume that there are M ETH PORTs, N VEIP PORTs, T IP HOST PORTs (here, IPv4 and IPv6 are not distinguished), and W GEM PORT PORTs on an ONU.

(1) The MAC bridge is related to the number of ETH ports, VEIP ports and IP HOST on the UNI side, and the same MAC bridge can only be related to one ETH/VEIP/IP HOST port. The ME ID of the MAC bridge ME is allocated according to table 1:

ONU UNI side port ID	Associated MAC bridge ME ID
		ETH
1	1
		ETH x	x
ETH M	M
		VEIP 1	M+1
VEIP y	M+y
		VEIP N	M+N
IP HOST 1	M+N+1
		IPHOST z	M+N+z
IP HOST T	M+N+T

TABLE 1 ME ID usage assignment for MAC bridge ME

Wherein 1< x < M, 1< y < N, 1< z < T, and x, y, and z are positive integers. For example, the ME ID assignment of the MAC bridge ME is as shown in fig. 11, 12, and 13.

(2) The number of the MAC bridge ports ME and ANI side GEMPORT is related to the number of the ETH ports, VEIP ports and IP HOST of the UNI side. The MAC bridge port ME is assigned according to tables 2 and 3:

TABLE 2 ME ID assignment for UNI side MAC bridge Port ME

TABLE 3 ME ID assignment for ANI side MAC bridge Port ME

Wherein 1< g < W, 1< k < M + N + T, and g and k are positive integers. The ME ID assignment of the MAC bridge port ME is shown in fig. 11, 12, 13, and 14.

(3) An attribute in the MAC bridge PORT ME is PORT NUM (PORT number), which is usually in the range of 0 to 255, and this attribute indicates that the MAC bridge PORT is connected to the MAC bridge using the PORT number of the MAC bridge, i.e., when different MAC bridge PORTs point to the same MAC bridge, this attribute cannot conflict. PORT NUM is assigned according to Table 4.

TABLE 4 PORT NUM Allocation of MAC bridge Port ME

Wherein, the following relation is required to be satisfied: w + M <254, W + N <254, W + T <254, (3+ W) × (M + N + T) < 65534. It should be noted that since the ETH, VEIP, and IP HOST PORTs on the UNI side do not use one MAC bridge at the same time, the PORT NUM used may be the same.

Table 5 lists the common morphological scenes of the current GPON ONU and the evolution directions that may appear in the future, and the allocation of ME ID and PORT NUM in various scenes meets the requirements of the relational expression.

TABLE 5 GPON ONU common scenarios and future contingency scenarios

When the OLT plans the service model, a user scene can be set firstly, or the ranges of the MAC bridge PORT ME ID and the PORT NUM which are required to be used by each user PORT and each service PORT can be reserved directly according to the requirements of the scene 7, so that the service model structure does not need to be re-planned no matter how the ONU product capability is expanded in a quite long period of time. According to the business model structure, development and maintenance personnel can easily construct a business model and focus on the problem when positioning the fault.

According to the technical scheme provided by the embodiment, the ME ID and the PORT NUM of the MAC bridge PORT required to be used by various service PORTs are fixedly distributed, so that the service model structure is relatively stable, the model is constructed without worrying about conflicts, the positioning problem is convenient and accurate, and the maintenance work is simple and easy. And designing an ME ID and PORT NUM distribution mode of an MAC bridge PORT on the OLT according to a recommended scene, and meeting the user requirements in a quite long period of time. When the scene changes, the scene can be customized according to the customer requirements, and the distribution mode on the OLT is dynamically adjusted.
