    • The present invention discloses a sub-rate transmission method for user data services in transmission devices of a Metropolitan Area Network (MAN). The method comprises the steps of: pre-configuring each transmission device to form forwarding table items representing corresponding relationship between self-defined tags and transmission lines; after receiving a user data frame, an original transmission device nesting a self-defined tag into the user data frame according to the forwarding table items to form a self-defined data frame, then transmitting the self-defined data frame; and after receiving the self-defined data frame, a terminal transmission device determining an output port for transferring the data frame by searching the forwarding table items with the nested self-defined tag, then deleting the nested self-defined tag and sending the original user data frame to the output port. The present invention, by nesting a self-defined tag, can greatly increase the number of Virtual Local Area Networks (VLANs) accommodated by a MAN as well as simplify the configuration of tags for user data to bring more convenience to users.
    • 本发明公开了一种用于城域网(MAN)的传输设备中的用户数据业务的子速率传输方法。 该方法包括以下步骤:预配置每个传输设备以形成表示自定义标签与传输线之间对应关系的转发表项; 在接收到用户数据帧之后,根据转发表项将原始传输设备嵌套到用户数据帧中以形成自定义数据帧,然后发送自定义数据帧; 并且在接收到自定义数据帧之后,终端传输装置通过使用嵌套的自定义标签搜索转发表项来确定用于传送数据帧的输出端口,然后删除嵌套的自定义标签并发送原始用户 数据帧到输出端口。 本发明通过嵌套自定义标签可以大大增加MAN容纳的虚拟局域网(VLAN)的数量,并简化用户数据的标签配置,为用户带来更多便利。
