Description

网络拓扑加入方法和装置 技术领域
本申请涉及但不限于通信领域，尤指一种网络拓扑加入方法和装置。
背景技术
术语解释：
QinQ：QinQ(802.1Q in 802.1Q)是基于802.1Q标准封装的隧道协议，在用户私有802.1Q的报文基础上，再封装一层802.1Q标签头，从而实现私网虚拟局域网(Virtual Area Network，简称为VLAN)在公网透传，达到二层虚拟专用网(Virtual Private Network，简称为VPN)的应用效果，其核心思想是将用户的私网VLAN标签(Tag)封装到公网的VLAN Tag上，报文带着两层802.1Q格式的VLAN Tag穿越服务商的骨干网络，从而为用户提供一种较为简单的二层VPN专线业务。
VPort：虚接口，无源光网络(Passive Optical Network，简称为PON)线卡的用户侧接口，是逻辑上的交换接口，能够和上联口进行交换，是业界内常使用的一种技术。
ServicePort：逻辑上抽象的业务接口，可以在ServicePort上进行VLAN转换、过滤等配置，ServicePort通常情况下可以理解为一条业务流，承载一个业务，是业界内常使用的一种技术。
PON技术目前已经是光接入网领域首选和主流技术，其在接入速率、带宽效率和分光比、全业务承载能力以及安全性方面都具有明显优势。PON技术还分为以太网无源光网络(EPON)和吉比特无源光网络(GPON)。其中，EPON技术由IEEE802.3EFM(Ethernet for the First Mile)工作组进行标准化；GPON技术是由国际电信联盟远程通信标准化组(ITU-T)提出并标准化。典型的PON系统由局侧的光线路终端(Optical Line Terminal，简称为OLT)、用户侧的光网络单元(Optical Network Unit，简称为ONU)以及光分配网络 (Optical Distribution Network，简称为ODN)组成。
光纤到办公室(Fiber To The Office，简称为FTTO)和光纤到楼(Fiber To The Building，简称为FTTB)是常用的两种业务场景。其中，FTTO是运营商针对业务容量较大的用户，将光纤直接引入到用户办公室；FTTB是运营商把光信号接入办公大楼，实现光信号接入，在大楼内部仍然使用同轴电缆、双绞线接入到各个用户。
目前运营商针对光纤到户(Fiber To The Home，简称为FTTH)已经可以使用自动工单进行PON业务的自动激活，但对于FTTO和FTTB，自动激活系统还存在一些问题和不足之处，主要体现在：
1、FTTO可以使用自动激活系统进行业务放装，但FTTO类型的ONU本身可以作为独立网元添加到整个网络拓扑中，与OLT之间可以通过ONU管理通道进行管理，目前的自动激活系统不能自动配置ONU管理通道；需要手动将其添加到拓扑中。
2、对于FTTB，其本身同样可以作为独立网元添加到网络拓扑中，与OLT之间可以通过ONU管理通道进行管理。但运营商目前基本是通过手动方式进行ONU管理通道的配置。
3、无论对于FTTO还是FTTB，管理通道无法自动配置，FTTB则完全手动配置，效率低，运维人员工作量大，并且成功率低。
ONU管理通道的配置主要包括管理IP、路由和管理VLAN，FTTO或FTTB都是通过OLT进行业务管理。此外，OLT的类型多种多样，对于管理VLAN的配置，不同类型的OLT支持不同的配置方式，早期的OLT不支持ServicePort，所以管理VLAN都是绑定到VPort上，后来的OLT则开始支持在VPort上创建ServicePort，通过ServicePort进行VLAN转换。在现网(当前已注册的网站)中，往往同时存在这两种OLT，如何能同时支持这两种OLT，或者自动选择一种合适的方式配置管理VLAN也是运营商比较关注的问题。
针对相关技术中FTTO和FTTB场景中ONU设备不能自动添加到网络拓扑中的问题，目前尚未提出有效的解决方案。

为了使本发明实施例的描述更加清楚，下面结合可选实施例进行描述和说明。
本发明可选实施例提供了一种灵活自动部署FTTO和FTTB业务场景ONU管理通道的方法，应用于EPON或GPON网元设备(包括光线路终端OLT和光网络单元ONU)管理领域。
为了运营商可以通过网管的自动激活系统，对FTTO和FTTB采用灵活并且自动的方式进行ONU管理通道的配置，本发明可选实施例提供了一种配置ONU管理通道的方案，包括：
对FTTO，ONU添加后，开始配置管理通道，ONU管理IP地址、路由和管理VLAN由离线ONU IP地址池分配，离线ONU IP地址池是缓存在网管数据库中的IP地址池，能够自动将未使用的IP地址分配给ONU。ONU添加完毕后，由离线ONU IP地址池分配一个未使用的IP地址以及该IP地址对应的路由和VLAN给该ONU，然后利用分配到的IP、路由和VLAN配置管理IP和管理VLAN。管理VLAN可以绑定到VPort，或使用管理VLAN在Vport上创建ServicePort，最后添加该ONU到网络拓扑中。
对FTTB，IP地址、路由和管理VLAN由运营商OSS系统下发，可能是在添加ONU后即配置，也可能是施工人员将ONU上线后再配置，取决于运营商的开通方式，管理VLAN的配置同FTTO，最后添加ONU到网络拓扑中。
对于FTTO场景而言：
首先，创建离线ONU IP地址池，将规划好的IP地址范围、IP对应的路 由和VLAN在网管上创建成离线ONU IP地址池。
然后，添加FTTO场景的ONU，自动配置管理IP和管理VLAN。配置管理IP需要的IP地址、路由和VLAN由步骤A中创建的离线ONU IP地址池分配，管理VLAN配置方式由ONU所在的PON口是否启用Smart QinQ决定。如果ONU所在PON口启用Smart QinQ，则绑定管理VLAN到VPort，否则使用管理VLAN在VPort上创建ServicePort。最后，添加ONU到网络拓扑。
对于FTTB场景而言：
添加FTTB场景的ONU，然后运营商OSS系统根据实际需要下发配置管理IP和管理VLAN，配置管理IP需要的IP地址和路由由OSS下发，管理VLAN配置方式由ONU所在的PON口是否启用Smart QinQ决定。如果ONU所在PON口启用Smart QinQ，则绑定管理VLAN到VPort，否则使用管理VLAN在VPort上创建ServicePort。最后，添加ONU到网络拓扑。
上述方案与现有的相关技术相比较，可以自动区分FTTO和FTTB业务场景的ONU管理通道的配置，ONU的管理IP配置则采用一种灵活的方式，既支持网管自动激活系统自动分配，也支持运营商OSS系统分配，而管理VLAN的配置则更灵活，能够自动判断是绑定管理VLAN到VPort还是在VPort上创建ServicePort，这对于不支持ServicePort的老OLT和支持ServicePort的新OLT同时存在时，本申请解决了困扰运营商的一个难题。
下面结合附图3和附图4说明FTTO和FTTB业务场景下配置ONU管理通道的过程。
首先进行预配置，在预配置过程中，创建离线ONU IP地址池；
在网管上创建离线ONU IP地址池，根据运营商给FTTO业务的ONU规划好的IP地址数据，创建IP地址池。IP地址池内容包括：IP地址范围以及IP对应的路由和VLAN。
图3是根据本发明可选实施例的FTTO业务场景ONU管理通道配置方法的流程图，如图3所示，该流程包括如下步骤：
步骤S302，添加FTTO ONU；
由网管的自动激活系统将FTTO ONU添加到OLT上。
步骤S304，离线ONU IP地址池分配IP地址；
网管的离线ONU IP地址池给该ONU分配一个没有被使用的IP地址、IP对应的路由和VLAN，IP地址、路由和VLAN用于步骤404配置ONU的管理IP，VLAN还用于配置步骤408或410配置当前ONU的管理VLAN。
步骤S306，配置该ONU的管理IP；
由步骤402分配得到的IP地址、路由和VLAN，配置该ONU的管理IP信息。
步骤S308，判断ONU所在PON口是否启用Smart QinQ；
ONU所在PON口启用了Smart QinQ使能，则需要把管理VLAN绑定到VPort上，跳至步骤S310；如果该PON口未启用Smart QinQ使能，则使用ServicePort方式进行VLAN转换，跳至步骤S312；
步骤S310，将管理VLAN绑定到VPort，然后转向步骤314；
把VLAN绑定到该ONU的VPort中。
步骤S312，将管理VLAN创建ServicePort，然后转向步骤314；
在VPort上使用分配到的VLAN创建ServicePort，通过ServicePort进行VLAN转换。
步骤S314，更新网管数据库；
更新数据库中该ONU的信息，把数据库中的IP地址信息更新到配置后的IP地址，保持OLT上该ONU的配置和网管数据库中该ONU的配置一致。
步骤S316，添加该ONU到网络拓扑中；
使用该ONU的IP地址该ONU添加到网络拓扑中，作为独立网元管理。
步骤S318，成功完成FTTO业务场景中ONU管理通道的配置。
图4是根据本发明可选实施例的FTTB业务场景ONU管理通道配置方法的流程图。FTTB业务场景下ONU管理通道配区别于FTTO在于FTTB场景下的ONU管理通道配置不一定是在添加ONU之后马上配置的，而可以是由运营商OSS系统主动下发IP地址、路由和VLAN数据，对已经添加到OLT  PON口下的ONU配置管理通道。
如图4所示，该流程包括如下步骤：
步骤S402，OSS系统下发配置FTTB ONU管理通道命令；
由运营商OSS系统对已经添加到OLT某PON口的ONU配置管理通道，命令中携带ONU位置信息、IP地址，路由和VLAN等信息。
步骤S404，配置ONU的管理IP；
根据命令中下发的IP地址，IP对应的路由和VLAN等信息配置ONU管理IP。
步骤S406，判断该ONU所在PON口是否启用Smart QinQ使能；
如果ONU所在PON口启用了Smart QinQ使能管理VLAN则需要绑定到ONU的VPort上，跳至步骤S408。如果未启用Smart QinQ使能，则使用ServicePort方式进行VLAN转换，跳至步骤S410；
步骤S408，将管理VLAN绑定到VPort，然后转向步骤412；
绑定管理VLAN到该ONU的VPort中。
步骤S410，在VPort上创建ServicePort，然后转向步骤412；
在VPort上使用OSS下发的管理VLAN创建ServicePort，通过ServicePort进行VLAN转换。
步骤S412，更新网管数据库；
更新数据库中该ONU的信息，把数据库中的IP地址信息更新到配置后的IP地址，保持OLT上该ONU的配置和网管数据库中该ONU的配置一致。
步骤S414，添加该ONU到网络拓扑中；
使用OSS系下发命令中的IP地址，将该ONU添加到网络拓扑中，作为独立网元管理。
步骤S416，成功完成FTTB业务场景中ONU管理通道的配置。
无论是FTTO还是FTTB，ONU的管理通道配置完毕后，施工人员到用户办公室或楼宇内安装好ONU，并把ONU接到OLT的PON口下，则OLT通过扩展OAM通道或OMCI将配置下发到ONU上，然后OSS系统可以在 该ONU上配置宽带、语音等数据业务。
