摘要： The invention is directed towards techniques for forwarding subscriber frames through a Multi-Protocol Label Switching (MPLS) aggregation network using MPLS labels. Layer two (L2) network devices, such as access nodes, of a service provider (SP) network implement MPLS functionality in the data plane, but do not implement an MPLS signaling protocol in the control plane. The L2 network devices include an interface for configuring a static pool of labels applied in the data plane of the L2 network device to output MPLS communications to the MPLS network. The access nodes may be configured by an administrator to maintain static pools of subscriber labels and MPLS labels. The access nodes autonomously allocate the subscriber labels to subscriber devices that request broadband services from a Broadband Services Router (BSR), and distribute the subscriber labels and MPLS labels as upstream assigned labels.
摘要翻译：本发明涉及通过使用MPLS标签的多协议标签交换（MPLS）聚合网络来转发用户帧的技术。服务提供商（SP）网络的第二层（L2）网络设备（诸如接入节点）在数据平面中实现MPLS功能，但是在控制平面中不实现MPLS信令协议。 L2网络设备包括用于配置应用在L2网络设备的数据平面中的标签的静态池的接口，以向MPLS网络输出MPLS通信。接入节点可能由管理员配置，以维护订户标签和MPLS标签的静态池。接入节点自主地将用户标签分配给从宽带业务路由器（BSR）请求宽带业务的用户设备，并将用户标签和MPLS标签分配为上行分配标签。

Layer two (L2) network devices, such as access nodes, of a service provider (SP) network implement MPLS functionality in the data plane, but do not implement an MPLS signaling protocol in the control plane. The L2 network devices include a pool of labels applied in the data plane of the L2 network device to output MPLS communications to the MPLS network, and a protocol that allows a layer three (L3) device to control provision of L2 functionality by the L2 device. The pool of labels is dynamically configured by the L3 device via the protocol. The access nodes distribute the subscriber labels and MPLS labels as upstream assigned labels.
