Abstract: In one embodiment, a method includes receiving a first packet sent by a first node. The packet includes a first Layer 3 source address, a first Layer 3 destination address, a first Layer 2 source hardware identifier, a first Layer 2 destination hardware identifier, and a first path identifier. The first path identifier is situated between a Layer 2 header of the first packet and a Layer 3 header of the first packet. The method includes automatically determining a first port of the first network element associated with a second node. The second node is associated with the first Layer 2 destination hardware identifier. A second path identifier is automatically determined based on the first port. The first packet is prevented from being delivered to the second node in response to determining that the first path identifier and the second path identifier are different.

Abstract: A method is provided in one example embodiment that includes receiving a radio signal stream, segmenting the radio signal stream based on a control word in the radio signal stream, mapping the segmented radio signal stream to a service class, transporting the segmented radio signal stream in packets through channels over a backhaul link, and maintaining the order of the radio signal stream over the backhaul link. In more particular embodiments, the backhaul link may use a DOCSIS link, the radio signal stream can be received using a Common Public Radio Interface, and the radio signal stream may include sub-streams transported through segmented channels over the backhaul link.

Abstract translation: 在一个实施例中，一种方法包括接收由第一节点发送的第一分组。 分组包括第一层3源地址，第一层3目的地址，第一层2源硬件标识符，第一层2目的地硬件标识符和第一路径标识符。 第一路径标识符位于第一分组的第二层报头和第一分组的第三层报头之间。 该方法包括自动确定与第二节点相关联的第一网络元件的第一端口。 第二个节点与第一个第2层目标硬件标识符相关联。 基于第一端口自动确定第二路径标识符。 响应于确定第一路径标识符和第二路径标识符不同，防止第一分组被递送到第二节点。
