具体实施方式
本发明实施例提供一种在光网络设备上感知服务提供商的方法、设备和系 统, 可以根据需要对端口和服务提供商进行灵活配置, 有利于用户业务开展。
首先, 应当理解, 尽管下面提供了一个或多个实施例的说明性实施方式, 但是所公开的系统和 /或方法可利用当前公知或现有的许多技术来实现。 本公 开决不应局限于下面示出的说明性实施方式、 附图和技术, 包括这里所图示和 描述的示例性设计和实施方式,但是本公开可以在所附权利要求的范围内及其 完全的等同范围内进行修改。
本发明实施例涉及 "开放式网络"。 请参见图 2B, 图 2B为一种 "开放式 网络" 示意图, "开放式网络" 指的是提供业务承载的业务承载网络和提供业 务的业务提供网络相分离,从属于不同提供商,例如一个用户申请一个带 IPTV 的光纤入户服务, 可能的模式为: 提供光纤入户的基础设施网络是基础设施提 供商 Z; 业务承载网络 201和业务承载网络 202提供业务承载, 业务承载网络 201和 202可以分别属于不同的提供商; 提供语音业务的是业务提供商 101 , 提供 IPTV服务的是业务提供商 102和业务提供商 103 , 用户可以在业务提供 商 102和业务提供商 103之间选择 IPTV服务。
为使本发明的目的、技术方案和优点更加清楚,在本发明以下的实施例中, "开放式网络" 以 FTTH接入方式为例, 结合附图对本发明实施例作进一步的 详细描述。
在本发明以下的实施例的 FTTH系统可以如图 3所示,用户终端通过用户 接入终端连接到承载网络的光网络单元 ONU/ONT; 在承载网络中, 光网络单 元 ONU/ONT通过光线路终端 (OLT )连接到 IP核心二层或三层虚拟公共网 络( IP CORE L2/L3 VPN )。 承载网络为多个业务提供商提供业务承载, 如承 载网络的 IP CORE L2/L3 VPN连接业务提供商 SP A、 SP B和 SP C。如无特别 说明, 以下的光网络单元 ONU/ONT用 ONT表示。
其中, 用户终端, 如电话、 个人计算机 PC、 IPTV终端等, 是指为用户提 供服务的终端设备。 用户接入终端, 如家庭网关 (Home Gateway, HG ), 是 指将用户终端连接到承载网络的接入层的网元,在 HG为数字用户线网络终端 的情况下, HG既可以作为 2层桥接装置也可以作为 3层路由装置。
本发明实施例在 ONT上支持动态维护访问控制信息的功能, 根据用户需 要访问的业务提供商, 建立相应的访问控制信息的信息表项, 并根据访问控制 信息的信息表项进行业务报文处理转发。
在 ONT上, 需要动态维护访问控制信息的信息表项, 执行操作在不同的 阶段可略有不同。 例如, 当用户接入终端接入系统时, 如果 ONT上没有该用 户接入终端的访问控制信息的信息表项, ONT 需要建立相应的访问控制信息 的信息表项, 其中, 所建立的访问控制信息的信息表项包含需要访问的业务提 供商的信息, 如业务提供商的标识( Service Provider Identifier, SP ID )。
请参见表 1 ,表 1示出了如图 3所示 FTTH系统支持 VLAN应用场景下的 访问控制信息的信息表项的一个实例。如表 1所示,访问控制信息的信息表项 可以包括如下几个域:
物理端口标识( Port ID ): 表示 ONT上有用户接入终端 (如 HG )接入的 物理端口的端口标识;
业务提供商标识 ( SP ID ): 用来标识需要访问的业务提供商;
外层 VLAN标识 ( Outer VLAN ID ): 用于标识服务提供商的虚拟网络; 业务传输通道标识 (如 GEM Port ID ): ,用于支持多端口复用,其中, GEM PORT( GEM端口)表示 GEM方式的业务传输通道, GEM Port ID 可以由 OLT 分配, GEM PORT ID是全局唯一的, 即不同的业务流分配不同的 GEM PORT
ID。
ONT在接收到任一物理端口的业务流时, 根据这张建立好的表, 对该物 理端口的业务流添加外层 VLAN ID和封装 GEM PORT ID。
表 1 ONT中的访问控制信息可以如下, 但不局限于此:
表 1
Port ID SP ID Outer VLAN ID GEM port ID
1 0x000b 0x0004-6 0x08~0f
2 0x000a 0x0001-3 0x01-07
3 OxOOOd 0x000a~c 0xl8~lf 4 null null null
值得注意的是, 上述访问控制信息的信息表项还可进行扩展, 例如还可以 扩展为包括报文特征信息 (例如 MAC地址、 IP地址、 用户位置信息等)、 月良 务质量 QoS信息等的一种或多种。 可以理解, 表 1是以 GPON ( ) 系统为例, 因而传输通道标识为 GEM port ID; 如果在 EPON系统中, 传输通道标识为逻 辑链路标识( Logic Link identifier, LLID ), 以此类推。
下面结合图 4A、 4B和图 5说明本发明实施例的具体实现过程。 制信息的信息表项维护操作。
在设备启动阶段, ONT根据自身的用户侧物理端口数量, 建立一张访问 控制信息的空白表项。 当然,如果 ONT已经建好了这张访问控制信息的表项, ONT设备启动时只需要启动加载。
请参见表 2, 表 2中 Port ID表示 ONT的用户侧物理端口标识; 服务提供 商标识 SP ID、 Outer VLAN ID、 GEM port ID都为空 "Null"。 表 2 中 ONT初 始化的访问控制信息可以如下, 但不局限于此:
表 2
Figure imgf000008_0001
下面以 ONT对用户侧物理端口 1的检测处理为例进行说明。
5501、 在 ONT上, 检查用户侧物理端口 1的链路状态。
具体的, 可以通过查询本地记录的物理端口的链路状态信息, 查询用户侧 物理端口 1的链路状态;或者通过用户侧物理端口 1发送链路状态查询请求报 文, 根据从用户侧物理端口 1接收到的应答报文确定物理端口 1 的链路状态 ( Down或 Up ), 可选的, 可以在 ONT上设定查询次数或查询周期, 在设定 的查询次数或查询周期内重复发送链路状态查询请求报文。
5502、 在 ONT上, 根据检测到的用户侧物理端口 1的链路状态判断是添 加还是删除 SP ID表项, 即如果用户侧物理端口 1的链路状态由断开( Down ) 变为连通(Up ), 具体如 HG上电时, 判定需要添加 SP ID表项, 则执行步骤 S503; 如果用户侧物理端口 1的链路状态由 Up变为 Down, 判定需要删除 SP ID表项, 则执行步骤 S508。
5503、 在 ONT上, 向用户侧物理端口 1对应的 HG ( SP B )发送 SP ID 请求报文。
5504、 在 ONT上, 判断是否接收到来自 HG ( SP B ) 的包含 SP ID的应 答报文; 如果收到则执行步骤 S505 , 否则执行步骤 S507。
5505、 在 ONT上, 将收到的应答 ·^艮文中的 SP ID填充到访问控制信息的 信息表项中, 即用户侧物理端口 1对应的 SP ID表项中, SP ID表项的具体内 容可参见表 1中 Port ID为 "Γ 的行数据。 可选的, ONT上可以在步骤 S506 给 HG ( SP B ) 回复一个确认消息, 如此即完成了 SP ID的自动感知过程。
此外, ONT也可以直接截获在该用户侧物理端口接收到的携带有服务提 供商信息的上行报文;从携带有服务提供商信息的上行报文中获得并记录服务 提供商信息。
其中, ONT可以根据本地数据库中记录的服务提供商信息和 VLAN信息 的对应关系, 得到 SP ID对应的 Outer VLAN ID, 具体实现时还可以结合相应 策略及上述服务提供商和 VLAN的信息综合得到。
其中, ONT的访问控制信息中的 Outer VLAN ID也可由上层网络设备分 配,例如: 上层网络设备通过光网络终端管理控制接口方式对 ONT进行配置; 或通过 TR069协议方式对 ONT进行配置;或通过配置管理系统直接连接或远 程控制方式对 ONT 进行配置。 其中, 上述上层网络设备可以是光线路终端 OLT、 设备管理系统 (Equipment Management System, EMS )、 配置服务器 ( Configuration Server, CS ) 的任意一种。
采用本发明实施例提供的方案, 内层 VLAN ID无需事先统一规划, 可以 由服务提供商根据需要自行设定。 具体实现时, ONT可将 SP ID上报给上层 网络设备, 上层网络设备根据 SP ID获得 SP ID对应的 VLAN信息, 并将获得 VLAN信息反馈给 ONT。
具体一种实现方式可参见如图 6A所示的系统示意图, 该系统包括: 动态 主机配置协议服务器(DHCP Server ), 可以为 HG的 DHCP请求提供相应的 IP; 配置服务器, 可以根据配置请求为 ONT提供相应的配置信息, 如 VLAN 信息、 VPN信息等。 其中, DHCP Server和配置服务器为功能实体, 这两个功 能实体可以存在于同一个物理实体中。 DHCP Server和配置服务器与 OLT逻辑 连接, 故而在如图 6A中用虚线表示。
ONT或 OLT包括 DHCP中继 ( Relay ) 功能实体, DHCP Relay功能实体 能够截获或解释 DHCP报文的特殊字段或者向 DHCP报文中插入特殊的字段。
下面以 OLT支持 DHCP Relay 功能为例进行说明。 HG是三层设备, 上电 或人为启动时会向网络侧请求 IP地址, IP地址请求报文通过 DHCP请求报文 发送给 DHCP服务器, 请求报文中可以通过特殊字段(例如标识字段)携带 SP信息,例如 SP ID; ONT可以从 HG接入的用户侧物理端口上接收到的 DHCP 请求报文中获得 SP信息,另夕卜, ONT还可以根据某一端口收到的 DHCP请求 报文, 添加该端口信息 (例如端口标识)到 DHCP请求报文的特殊字段中。 OLT监控 HG DHCP请求报文, 通过 DHCP请求报文中的特殊字段可以获知 HG所属的 SP信息以及该 HG所连接的 ONT的端口信息。 OLT可以根据 HG 的 SP信息和 HG所连接的 ONT的端口信息, 下发相应的配置信息给 ONT。 OLT也可以向配置服务器发送配置请求, 从配置服务器请求对应的配置信息 后, 把配置信息通过 DHCP报文下发给 ONT, 其中, 配置请求包括 HG所属 的 SP信息,也可以包括该 HG所连接的 ONT的端口信息。配置信息包括对应 端口对应的 Outer VLAN ID , ONT收到对应的 Outer VLANID后, 就可以进行 相应的外层 VLAN封装。 另外, 配置信息还可以包括对应端口内层虚拟局域 网标识( Inner VLAN ID ), ONT接收到 Inner VLAN ID后, 可以提供给 HG或 存储在本地。
另一种实现方式可参见如图 6B所示的系统示意图, 该系统包括: 终端管 理服务器(也可称 HG的配置服务器)和配置服务器, 其中, 终端管理服务器 可以是支持 TR069协议的服务器, 提供 HG的配置服务功能; 配置服务器, 根据配置请求为 ONT提供相应的配置信息, 如 VLAN信息、 VPN信息等。 其 中, 终端管理服务器和配置服务器为功能实体, 这两个功能实体可以存在于不 同物理实体也可以存在于一个物理实体中。 其中, 终端管理服务器与 HG逻辑 连接, 配置服务器与 OLT逻辑连接, 终端管理服务器和配置服务器之间逻辑 连接, 故而在图 6B中用虚线表示。
HG上电后, 会通过相应的方式向终端管理服务器(HG的配置服务器) 发送配置请求或报告状态信息 (具体方法参见已有技术), 优选的, 请求配置 完成后, 终端管理服务器向配置服务器发送 HG所连接的 ONT标识信息, 可 以包括 SP信息, 如 SP ID, 请求配置服务器对 ONT重新进行配置。 配置服务 器生成相应的配置信息并通过 OLT下发给 ONT。
S507: 报告出错, 结束该用户侧物理端口的查询过程。
S508: 在 ONT上, 删除用户侧物理端口 1对应的 SP ID表项。
ONT对用户侧物理端口 2和 3的检测处理过程与步骤 S501 ~ S508相同, 得到的结果参见表 1所示。
请参见图 7, 图 7为利用上述过程建立的访问控制信息进行报文转发的系 统框图。 具体实现过程可以如下:
ONT接收来自 HG的上行报文, 该上行报文中包括内层 VLAN ID。
ONT查询该 HG对应的外层 VLAN ID和 GEM PORT ID。 具体可以是根 据 HG对应的用户侧物理端口 PORT ID查询访问控制信息的信息表项; 如果 上行报文中携带 SP ID, 则也可根据 SP ID查询访问控制信息的信息表项; 如 果访问控制信息的信息表项中记录有上行报文的特征信息,还可以利用某些特 征信息作为索引查询访问控制信息的信息表项。
ONT将外层 VLAN ID和 GEM PORT ID按照一定的封装格式封装到上行 报文中, 例如通过 IEEE 802.1Q定义的 VLAN (虚拟本地局域网 )来实现。
ONT将封装后的报文发送给 OLT, 以便 OLT转发。
图 8所示的光网络设备 800可以包括: 用户侧端口模块 810、 转发处理模 块 820、 网络侧端口模块 830、 控制处理模块 840、 存储模块 850。
其中, 用户侧端口模块 810可以包括一个或多个用户侧物理端口,每一个 用户侧物理端口可以连接一个用户接入终端, 如家庭网关 HG。

存储模块 850, 用于存储访问控制信息。
控制处理模块 840还可以包括, 配置信息获取模块 844。
配置信息获取模块 844, 用于获取配置信息, 将获取的配置信息提供给信 息控制模块 842, 由信息控制模块 842添加到相应的表项中, 所获取的配置信 息包括外存虚拟局域网标识 Outer VLAN ID、内存虚拟局域网标识 Inner VLAN ID、 GEM PORT ID、 服务质量 QoS信息、 其它配置参数中的一种或多种。 具 体可以采用上述图 6A或图 6B的方式获取配置信息。 其中, HG所属的 SP信 息、 VLAN等信息可以在 HG上电前预先由 OLT、 各种服务器等预先配置在 ONT中, HG上电后由配置信息获取模块 844根据从 HG上行报文中获得的 SP信息查找本地数据库获得。
处理模块 843 , 用于在该用户侧端口上接收到上行报文时, 根据访问控制 信息的信息表项在接收到的上行报文中添加外层 VLAN ID和 GEM PORT ID。
在一种应用场景下, 光网络设备 800还可以包括:
