Description

光网络单元DPU设备管理方法、装置及系统 技术领域
本发明涉及通信领域，具体而言，涉及一种光网络单元DPU设备管理方法、装置及系统。
背景技术
分配处理单元(Distribution Point Unit，简称为DPU)设备只指是放在分支点(Distribution Point，简称为DP)节点的设备。网络侧是无源光网络(Passive Optical Network,简称为xPON)/以太网上联口，用户侧是VDSL2/G.FAST数字用户线(Digital Subscriber Line，简称为DSL)接口，在相关技术中，目前DPU设备管理模型采用网络配置NETCONF协议，该协议一般是通过承载IP协议。如果上联设备是光线路终端(tical line terminal，简称为OLT)，那么永久管理器代理(Permanent Management Agen，简称为PMA)可以放置在OLT设备上，即使是OLT和光网络单元(Optical Network Unit，简称为ONU)是邻接设备，如果还是采用IP承载方式，那么就需要在OLT和DPU都配置IP地址，这涉及到IP地址分配，管理等问题，带来网络管理的复杂度，也增加了DPU设备的复杂度。
目前常规的管理方式是采用IP地址的管理方式，图1是相关技术中采用IP地址对DPU设备进行管理的方式的示意图，如图1所示，包括用户终端设备(Customer Premise Equipment,简称为CPE)，这种方式的缺点是：每个DPU都需要分配IP地址，IP地址分配，标识和管理是非常复杂的，开通和维护工作量巨大。
另外一种方式是在OLT和DPU之间使用GPON(千兆比无源光网络，GPONGigabit-Capable PON)/XG-PON1(万千兆比特无源光网络)等技术时，使用专门的光网络单元管理控制接口(Management and Control Interface，简称为OMCI)是GPON标准中定义的一种OLT与ONT之间信息交互的协议)通道来承载NETCONF报文，这个通道用于OLT和ONU之间的配置和通知,图2是相关技术中OLT和ONU之间的OMCI管理通道的示意图，图3是相关技术中采用NETCONF over OMCI管理方式的示意图，如图2和图3所示。基于这个通道的实现方案是NETCONF over OMCI的方式，这个功能采用PON底层机制，不需要配置IP地址等就可以实现OLT和ONU配置管理和ONU告警通知。但这个OMCI通道中，每个OMCI报文最大字节小于53 字节，如果用OMCI承载NETCONF报文，那么就涉及到NETCONF报文分片和重组，可扩展性很差。
针对相关技术中，针对光网络单元DPU设备管理复杂度高，可扩展性差的问题，还未提出有效的解决方案。

第一通道单元，千兆比无源光网络GPON的GPON封装方式GEM通道；
第二通道单元，以太网无源光网络EPON的逻辑链路标记LLID通道；
第三通道单元，以太网的虚拟局域网VLAN通道。
该第一通道单元，设置为该特定业务承载通道为千兆比无源光网络GPON的GPON封装方式GEM通道情况下，该NET-CONF报文承载在GEM帧上，该GEM帧长度大于该NET-CONF报文长度。
该第三通道单元，设置为该特定业务承载通道为以太网的虚拟局域网VLAN通道的情况下，光线路终端OLT和光网络单元DPU间建立特定业务承载通道的寻址方式包括以下之一：在该VLAN ID和该DPU是一一对应的情况下，且一个该VLAN有多个DPU设备，根据该DPU设备的MAC地址进行识别和区分；在VLAN承载的情况下，报文源MAC地址是设备的MAC地址，目的MAC地址，在不知道对端MAC地址的情况下，采用广播地址发送，得到对方MAC地址的情况下，填充对端MAC地址。
在本实施例中，该装置还包括：接口器件，设置为通过北向接口方式，该PMA使用一个IP地址与网管配置服务器连接，该连接的上层协议包括：网络配置协议NET-CONF，简单网络管理协议SNMP，人机交换协议TL1。
在本实施例中，还有一种光网络单元DPU设备管理系统，包括实施例的任一项该的装置，用于实现上述实施例的方法。
下面结合优选实施例和实施场景对本发明进行详细说明。
本优选实施例公开了一种管理方法，用于通过在OLT上的PMA管理DPU设备。
a、在OLT和DPU间设定一个特定业务承载通道，如GPON的GEM通道、EPONEPON(Ethernet Passive Optical Network，以太网无源光网络)，的LLID、或以太网的一个特定虚拟局域网(Virtual Local Area Network，简称为VLAN)；
b、OLT的PMA接收到来自于配置服务器的NETCONF配置报文，根据管理的对象通过OLT和DPU间的特定的业务承载通道发送给DPU；
C、DPU把通过OLT和DPU间的特定的业务承载通道发送的管理报文解析出来直接完成NETCONF的管理数据的解析，并配置DPU的相关参数；
通过OLT和ONU侧，终结该通道，分别把报文提取到设备管理CPU；这样OLT和ONU侧就可以建立一个通明的通道用于承载NET-CONF协议。
在北向接口方式，所述的PMA使用一个IP地址与网管配置服务器连接，上层协议可以是网络配置NETCONF协议，或SNMP，人机交换协议TL1(Transaction Language-1)等其他方式。
针对GPON的G-PON封装模式GEM(G-PON Encapsulation Mode,简称为GEM)通道和EPON的逻辑链路标记(Logical Link Identifier，简称为LLID)通道，这个通道和DPU是一一对应的。但针对采用VLAN的寻址方式，有两种方式：
如果VLAN ID和DPU是一一对应的，这时候实现方案和GEM/LLID类似，如果是一个VLAN有多个DPU设备，这时候就需要根据DPU设备的MAC地址进行识别和区分。
使用VLAN承载时，报文源MAC地址是设备的MAC地址，目的MAC地址，如果不知道对端MAC地址，可以采用广播地址发送，当得到对方MAC地址的时候，可以填充对端MAC地址。
图6是根据本发明优选实施例的采用NETCONF over GEM/LLID/VLAN管理方式的示意图；
如图6所示，本优选实施例不需要分配IP地址，采用是把GEM通道当作一个OLT和ONU之间的透明通道，直接把NETCONF报文承载在GEM帧上。具体方法如下：
s1、在OLT和DPU间设定一个特定业务承载通道，如GPON的GEM通道、EPON的LLID、或以太网的一个特定VLAN；
s2、OLT的PMA接收到来自于配置服务器的NETCONF配置报文，根据管理的对象通过OLT和DPU间的特定的业务承载通道发送给DPU
s3、DPU把通过OLT和DPU间的特定的业务承载通道发送的管理报文解析出来直接完成NETCONF的管理数据的解析，并配置DPU的相关参数
在北向方向，所述的PMA使用一个IP地址与NETCONF配置服务其连接；
S4、如果是采用VLAN承载方式,且VLAN内存在多个DPU设备的话,需要在OLT上配置MAC地址和DPU对应关系,以方便寻址。
在本文中，GPON指GPON及其后续GPON/XGPON1/NGPON2等同一系列标准，EPON指EPON一起后续的10G EPON等同一系列标准。
