在下行报文传输过程中:
网络接口板, 用于获取来自公网的报文, 并获取其中的 S_VLAN ID和 C-VLAN ID;根据 S_VLAN ID与用于标识业务类型的第一虚拟局域网标识 VLAN ID 和用于标识用户的第二 VLAN ID 的对应关系, 将报文中的 S_VLAN ID转换为第一 VLAN ID和第二 VLAN ID ,并且 ,根据 C-VLAN ID 与用于标识用户接入设备的第三 VLAN ID 的对应关系, 将该报文中的 C-VLAN ID转换为第三 VLAN ID;将携带有第一 VLAN ID、第二 VLAN ID 和第三 VLAN ID的报文发送给核心交换系统中的交换芯片;
交换芯片, 用于接收来自网络接口板的报文。
所述交换芯片, 记录发送报文的网络接口板所对应的交换芯片端口、 该报文中的 MAC地址、 以及第三 VLAN ID, 并且, 将该报文发送给用户 设备接口板。
用户设备接口板, 用于接收来自核心交换系统的报文, 删除该报文中 的第三 VLAN ID后, 将报文发送给用户接入设备;
用户接入设备, 用于接收来自用户设备接口的报文, 删除该报文中的 第二 VLAN ID后, 将报文发送给用户端的路由设备;
用户端的路由设备, 用于接收来自用户接入设备的报文, 删除该报文 中的第一 VLAN ID后, 将报文发送给用户设备。
下行报文, 即网络接口板接收到的来自公网的报文, 其结构如图 3 所 示, 包括目的 MAC地址、 源 MAC地址、 外层虚拟局域网标签、 内层虚拟 局域网标签、 类型长度、 净荷、 校验位。 其中, 外层虚拟局域网标签包括 S_VLAN ID, 内层虚拟局 ¾网标签包括 C-VLAN ID。
本发明实施例提供的技术方案,使用三层 VLAN ID分别标识不同用户 接入设备、不同用户和不同业务,如果接入系统承载 10块用户设备接口板, 每个接口板提供 4个光纤接口, 用分路光纤, 每个光纤接口承载 32个用户 接入设备, 这样就可提供 1280个用户接入设备, 假设每个用户接入设备有 24个用户路由接入端口, 那么共有 30720个用户路由设备接入系统; 假设 每个用户有 4种不同业务, 那么就需要 12万个 VLAN ID作标识。 而以太 网中的核心交换系统里的交换芯片仅提供了 4K VLAN ID资源, 所以本发 明实施例使用三层 VLAN ID汇聚, 即在每一层设备 (包括路由设备、 用户 接入设备、 用户设备接口板)预设特定的一组 VLAN ID, 然后在网络接口 板上进行 VLAN ID汇聚和 QinQ转换,使报文带着业务运营商需要的 VLAN ID进入公网。
用户接入设备是多端口的, 每个端口和一个用户绑定。 一个用户接入 设备负担多个用户的业务处理。报文经过用户端的路由设备后, 变成单 Tag 报文, 即只有一个 VLAN ID的报文, 该 VLAN ID用于标识用户的业务类 型; 报文经过用户接入设备时又增加了一层 VLAN ID, 用于标识用户; 报 文进入用户接入设备与主控板设备的接口板(即用户设备接口板), 又被添 加一层 VLAN ID, 用于标识用户接入设备; 报文从用户端设备与主控板设 备的接口板进入主控板中的以太网交换芯片,此时带有上述三个 VLAN ID。
在用户端口对应的以太网交换芯片的端口上, 即网络接口板上, 应用
VLAN转换策略,将指定的用户接入设备的带有指定业务的 VLAN ID的报 文转换成新的内层 VLAN ID, 即将 VLAN ID_1 和 VLAN ID_2转换为 C—VLAN ID, 并记录 VLAN ID_1和 VLAN ID_2, 与 C—VLAN ID的对应 关系。
该 C_VLAN ID用于标识指定用户接入设备的指定业务,网络接口板用 转换后得到的 C_VLAN ID代替原报文的 VLAN ID_1和 VLAN ID_2,然后 根据 QinQ规则, 修改外层 VLAN标签中的 VLAN ID, 使其与业务运营商 的 VLAN ID相同,即将 VLAN ID_3转换为 S_VLAN ID,然后发给主干网。
在上述 VLAN转换过程中, C_VLAN ID用于标识指定用户接入设备的 指定用户 , 网络接口板用 C_VLAN ID代替原报文的 VLAN ID_1和 VLAN ID_2, 这样就可以实现不同的用户分组或不同的业务分组, 使得不同的用 户组、 不同的业务组或不同用户的不同业务, 具有不同的传输隧道, 可用 于实现光纤到楼的各种应用场景。
在用户不多的情况下,也可以将用户和业务进行 1比 1的 VLAN转换, 即转换后的报文中使用两个不同的 C_VLAN ID分别代替原报文的 VLAN ID_1和 VLAN ID_2, 用以标识不同用户的不同业务, 但此时占用的 VLAN 资源比较多。
从网络端口进入接入系统的报文的外层 VLAN标签中的 S_VLAN ID 是业务运营商的 VLAN ID, 进入网络接口板后, 经过反 QinQ转换和反 VLAN汇聚,报文从双 VLAN Tag或单 VLAN Tag变成三 VLAN Tag, 其中 外层 VLAN Tag中的 VLAN ID_3是标识用户接入设备的 VLAN ID, 中层 VLAN Tag中的 VLAN ID_2是标识用户的 VLAN ID, 内层 VLAN Tag中的 VLAN ID_1是标识业务类型的 VLAN ID。交换芯片会根据报文上行传输时 记录的用户设备接口板所对应的交换芯片端口、该报文中的 MAC地址、 以 及 VLAN ID_3, 将报文送到指定用户接入设备, 用户接入设备根据报文中 标识用户的 VLAN ID_2, 将报文送出端口, 报文进入用户的路由设备, 根 据报文中标识业务类型的 VLAN ID_1进入用户设备(PC、 IPTV机顶盒、 固定电话等)。
此外,在用户端口和 /或网络端口传输 VLAN ID数据包的情况下,用户 端口和网络端口中发送 VLAN ID数据包的源端口, 将 VLAN ID数据包的 源媒体访问控制地址信息写入以太网交换芯片的媒体访问控制地址表中。 这里所说的 VLAN ID是标识用户接入设备的 VLAN ID。
通过上述技术方案, 能够在以太网交换系统上实现各种光纤到楼 ( FTTB , Fiber to The Building )场景, 而且能够节约 VLAN ID资源。
下面介绍一下本发明实施例提供的方法流程。
报文上行进入公网的处理过程如图 4所示, 包括步驟:
S101 : 报文进入用户端的路由设备, 用户端的路由设备在报文中添加 VLAN ID_1 , 用以标识不同业务; 然后报文进入用户接入设备, 用户接入 设备在报文中添加 VLAN ID_2, 用以标识不同用户; 然后报文进入用户接 口板, 用户接口板在报文中添加 VLAN ID_3 , 用以标识不同的用户接入设 备。
S102: 报文带着上述三层 VLAN ID进入交换芯片, 在用户接口板对应 的交换芯片端口和 VLAN ID_3里学习 MAC地址, 即交换芯片记录发送报 文的用户设备接口板所对应的交换芯片端口、 该报文中的媒体接入控制 MAC地址、 以及 VLAN ID_3。 然后报文进入网络接口板。 S103:网络接口板将用于标识用户和业务的 VLAN ID汇聚成 C-VLAN, 并记录 C-VLAN和 VLAN ID_1及 VLAN ID_2的对应关系。
S104:网络接口板根据 C_VLAN和 VLAN ID_3进行 QinQ转换, 将 VLAN ID_3替换成业务运营商指定的 VLAN ID, 即 S—VLAN ID, 并记录 S_VLAN ID和 VLAN ID_3的对应关系。
