Description

自动发现同轴宽带接入头端的方法、 管理方法及系统
技术领域
本发明涉及基于光和同轴混合接入网络 (PON+EOC)领域, 特别是涉及, 一种自动发现同轴宽带接入头端的方法、 管理 EOC头端设备的方法及系统。 背景技术
随着信息化社会对于融合业务的快速增长需求, 宽带接入网的建设成为 提供融合业务的瓶颈。 鉴于接入网建设所需的巨额成本, 基于现有网络资源 的整合、 改造并快速、 低成本的提供融合业务成为当今三网融合课题研究的 重点方向。 基于光和同轴混合接入网络技术是其中重要的解决方案之一。
PON ( Passive Optical Network , 无源光网络)是一种点到多点的光网络, 其结构如图 1所示, 系统主要由网元管理系统(EMS ) 、 局端的光线路终端 ( OLT ) 、 光配线网络(ODN )和用户端的光网络单元(ONU )组成。
EOC ( Ethernet Over Coax, 基于以太网的同轴电缆)是一种点到多点的 基于同轴电缆的网络, 其结构与 PON类似, 如图 2所示, 系统主要网元管理 系统( EMS ) 、 CBAT ( Coax Bandwidth Access Terminal, 同轴宽带接入头端, 也称为 Coax Bandwidth Access Headend, 同轴宽带接入头端 ) 、 同轴配线网 络(CDN )和用户端的同轴网络单元(CNU )组成。
PON+EOC是一种二级的点到多点的网络, 由 PON和 EOC网络串联组 成, 其结构如图 3所示, PON网络的 UNI ( User Network Interface, 用户网络 接口)节点与 EOC网络的 SNI ( Service Node Interface , 业务节点接口 )节点 相连接。 二级网络釆用统一 EMS网管的方式进行管理。
现阶段 PON+EOC网络中的 EOC头端发现和配置管理有以下几种方式: 第一种管理方式是: 在 EOC网管逐一静态配置 EOC头端 VLAN (虚拟 局域网)、 IP地址等相关信息, 并且逐一在 EOC头端设备上以带外模式静态 预配置 VLAN、 IP地址和 EOC网管的 IP地址等相关信息。 EOC设备并网运 行后, 在 PON网络链路建立连接的情况下, EOC头端依据本地保存的网管 IP地址通过 载在业务通道的 SNMP ( Simple Network Management Protocol, 简单网络管理协议) 注册到网管, 从而完成 EOC头端设备的发现。 EOC 网 管对 EOC头端设备完成状态监测、 EOC头端和终端的业务属性和参数的配 置和管理,从而打通 EOC链路通道,即完成了 PON+EOC通道的建立和管理。
该方式需要带外模式静态预配置 EOC头端 VLAN、 IP地址和网管 IP地 址等相关信息, 完成网管对 EOC头端的发现和配置。 网管仅支持 PON网络 或者 EOC 网络的拓朴关系的展现和端口定位关系。 管理消息釆用端到端的 SNMP协议。
该方式的带来的问题是:
1 )需要本地带外方式在 EOC头端设备上预配置初始化参数, 增加运营 商各部门业务开通流程之间的紧耦合度和复杂化, 并增加运维部门后期的管 理成本。
2 ) PON和 EOC网络之间管理信息隔离, 网管不能统一展示接入网络整 体的拓朴结构和端口之间的连接关系, 增加了网管和运维部门网络管理的难 度。
第二种管理方式是:逐一在 EOC头端设备上以带外模式静态预配置 EOC 头端 IP地址等相关信息。 EOC设备并网运行后, 在 PON网络链路建立连接 的情况下, EOC头端在业务通道以广播报文的形式发送自己的 IP地址等相关 信息。 该信息 ONU可以不处理, 直接透传给 OLT; 也可以终结该报文, 添 加有关 ONU IP地址、 接收端口等信息后在业务通道上以广播报文的形式转 发给 OLT, OLT终结该广播报文。 OLT以此信息构建本地 MIB库;对于 ONU 直接透传给 OLT的方式, OLT通过 OAM通道以反查 ONU端口的用户 MAC 地址信息的形式,进行端口定位。 OLT通过 SNMP协议把 EOC头端 IP地址、 端口定位等信息上报网管, 从而完成 EOC头端设备的自动发现和端口定位。 网管通过 SNMP协议完成对 EOC头端的状态监测(或者通过 OLT完成 EOC 头端的状态检测) 、 EOC头端和终端的业务属性和参数的配置和管理。 从而 打通 EOC链路通道, 即完成了 PON+EOC通道的建立和管理。
该方式需要带外模式静态预配置 EOC头端 IP地址等相关信息, 以广播 报文的形式发送到 PON网络, OLT终结该消息, 并构建本地 MIB库, OLT 通过 SNMP协议上报 EOC头端信息给网管, 从而完成 EOC头端设备的自动 发现和端口定位和后续的配置。 该方式的带来的问题是:
1 )需要本地带外方式在 EOC头端设备上预配置初始化参数, 增加运营 商各部门业务开通流程之间的紧耦合度和复杂化, 并增加运维部门后期的管 理成本。
2 ) EOC头端以广播报文的方式发送自己的初始信息给 OLT, OLT一般 会对上行的广播报文设置限速, 因此, 该报文存在丟弃的可能, 造成 EOC头 端发现过程加长; 另外, OLT需要逐一检测广播报文, 大大加重了 OLT的处 理负担, 使 OLT存在可靠性的风险。
3 )技术上不是所有的 OLT都支持对上行广播报文的解析, 因此, 该管 理方式不具有普遍意义。

EOC头端设备在无预配置 VLAN、 IP地址的情况下, 可以借助 ONU普 遍支持的组播帧格式的 BPDU( Bridge Protocol Data Unit,网桥协议数据单元) 报文的解析功能,通过自定义的 BPDU扩展报文发送 EOC头端设备的基本信 息 (该信息可以自定义,例如: EOC头端的 IP地址、掩码、虚拟局域网( VLAN ) ID、 MAC ( Medium Access Control,介质访问控制)地址、 EOC制式、 型号、 生产厂家、 软件 /硬件版本、 MIB库版本等)寻找与自己连接的 ONU;
步骤 Sl l、 ONU捕获步骤 S10中的 文后, 完成 EOC头端的发现, 并 以自定义单播帧格式回应, 从而 EOC头端完成 ONU的发现。
优选地, 步骤 S12、 EOC头端设备向 ONU发送注册请求报文;
具体地, EOC头端设备以自定义单播帧格式给 ONU发送注册请求报文。 步骤 S13、 ONU终结该注册请求报文, 从所述注册请求报文中提取出所 述 EOC头端设备的注册信息, 将所述注册信息与对应的 ONU端口信息发送 给 OLT;
具体地, ONU从所述注册请求 4艮文中提取出 EOC头端设备的注册信息, 并配置添力口对应的端口信息, 通过自定义的 OAM ( Operation Administration Management,运行管理维护)扩展才艮文或 OMCI( ONU Management and Control Interface, ONU管理控制接口)扩展报文送达 OLT;
步骤 S14、 OLT接收到所述扩展报文, 发现 EOC头端设备;
具体地, OLT认证通过后, 解析所述扩展报文, 发现 EOC头端, 根据扩 展报文中携带的 EOC头端基本信息和 ONU端口信息, 构建本地 EOC 头端 设备的 MIB ( Management Information Base, 管理信息库) , 完成 OLT对
EOC头端的自动发现。
优选地, 步骤 S15、 OLT将 EOC 头端设备的 MIB发送给网管, 所述网 管接收到 EOC 头端设备的 MIB后发现所述 EOC 头端设备。
该方法无需要预配置 EOC头端的 IP地址和网管 IP地址等相关信息, 可 以釆用自定义的 BPDU报文完成 EOC 头端设备被 ONU发现的过程, ONU 作为转发节点, 釆用自定义单播帧与 EOC头端通信, 釆用 OAM/OMCI扩展 报文与 OLT通信, 而从完成 OLT和网管对于 EOC头端的发现。
图 7所示, 包括下面步骤:
步骤 S20、 OLT发现同轴宽带接入头端后, 进行 CBAT注册, 将预先配 置的 EOC参数模板发送给 CBAT; 所述 CBAT根据所述 EOC参数模板进行 配置。 优选地, 在 OLT进行 CBAT注册的过程中, OLT记录 CBAT与 ONU 端口的对应信息, 构建 CBAT的 MIB , 将所述 CBAT的 MIB发送给网管。
优选地, 网管接收到 CBAT的 MIB发现所述 CBAT后, 通过 SNMP与 CBAT建立管理通道。

与现有第一种管理技术方式相比较, 本实施例优点主要体现在: 无需预 配置 EOC头端 VLAN、 IP地址和网管 IP地址等相关信息; PON系统了解下 挂的 EOC头端以及端口连接关系。 支持 PON+EOC统一管理, 网管可以动态 展现 PON+EOC网络拓朴结构, 此举简化了 EOC设备的开通程序, 降低了工 作量, 增强了系统管理和运维的便利性。
与现有第二种管理技术方式相比较 ,本发明的实施方式优点主要体现在: 无需预配置 EOC头端 VLAN、 IP地址等相关信息, 简化了 EOC设备的开通 程序, 降低了工作量; 另外, EOC头端的发现过程釆用了 ONU普遍支持的 BPDU报文 +单播报文 +OAM/OMCI管理消息的形式,避免釆用端到端的广播 帧对 PON网管安全管理造成的冲击以及消息被丟弃的可能性; OLT也无需改 变现有的软件架构, 无需重新定向、 解析特定广播帧, 也不会显著增加 OLT 的负荷, 该方法综合考虑了现网的实际情况, 显著降低了解决方案在现网实 施的难度和风险, 提高了网络安全性和可靠性, 具有操作性强的特点。 下面以一具体实施例对本发明做详细的说明。

步骤 104和 105, EOC头端启动缺省定时器 T1 ,定时发送自定义的 BPDU 报文, BPDU报文中包含 EOC头端的基本信息, 等待 ONU的应答;
自定义的 BPDU报文的格式如图 4所示, 其中,
DMAC (目的 MAC )为特定的 BPDU报文地址;
SMAC (源 MAC )为 EOC头端自己的 MAC地址;
协议 ID表示特定的 BPDU报文;
Payload字段中包括 EOC头端的基本信息, 例如: EOC头端 IP地址、 掩 码、 VLAN ID、 MAC地址、 EOC制式, 型号、 生产厂家、 软件 /硬件版本、 MIB库版本等。
步骤 106, ONU终结所述自定义的 BPDU报文,取出 EOC头端 MAC地 址信息, 并建立与 EOC头端 U I端口定位的表单, 完成 EOC头端的发现; 步骤 107, ONU向 EOC头端回复确认信息,该确认信息为自定义单播帧 格式, 如图 5所示, 其中, 自定义以太网帧类型 (Ether Type), 与标准定义不 冲突即可, 例如可选 0X88B8 ; Payload字段中可以包括: EOC头端交互信 息和参数, 该 Payload字段中的信息可以自定义, 例如: OLT转发给 CBAT 的扩展 OAM信息的内容。 ONU可以通过此字段封装后, 发给 CBAT。

网管不仅保存有 EOC头端的配置模板, 也保存有 EOC头端下挂的 CNU 的配置模板。 当网管发现 CBAT后, CBAT会把 CNU的注册信息报给网管, 那么网管就可下发 CNU的配置参数集(profile ) 了。
步骤 120 , EOC头端定期更新带有端口定位信息的 CNU MIB, 网管通过
SNMP协议取出该 CNU MIB ,完成 PON+EOC网络拓朴结构的动态更新和展 示。
