Abstract: A device may identify a portion of a label-switched path (LSP) on which a simple hierarchical LSP (sH-LSP) is to be used for transferring traffic via a network. The device may determine attribute information associated with the sH-LSP. The attribute information may include information associated with one or more characteristics of the sH-LSP. The device may provide an indication associated with identifying an available sH-LSP or creating a sH-LSP. The indication may include the attribute information associated with the sH-LSP, and may be being provided to cause the sH-LSP to be created on the portion of the LSP or an available sH-LSP, associated with the portion of the LSP, to be identified. The device may receive, based on providing the indication, an identifier associated with the sH-LSP. The device may cause the LSP to be set up based on the identifier associated with the sH-LSP.

Abstract: An apparatus may include a processor and a control plane that directs the processor to (1) detect that at least a portion of an initial branch path of a point-to-multipoint label-switched path has failed over to a failover route that rejoins the initial branch path at a network node and (2) establish an alternate branch path that merges with the initial branch path at the network node. The apparatus may also include a network interface and a data plane that uses the network interface to transmit data via the alternate branch path, where after the data plane begins transmitting data via the alternate branch path, the control plane instructs the network node to forward data from the alternate branch path rather than from the failover route. Various other apparatuses, systems, and methods are also disclosed.

Abstract: An apparatus may include a processor and a control plane that directs the processor to (1) detect that at least a portion of an initial branch path of a point-to-multipoint label-switched path has failed over to a failover route that rejoins the initial branch path at a merge-point device and (2) establish an alternate branch path that merges with the initial branch path at the merge-point device. The apparatus may also include a network interface and a data plane that uses the network interface to transmit data via the alternate branch path while data is still being transmitted via the initial branch path, where after the data plane begins transmitting data via the alternate branch path, the control plane instructs the merge-point device to forward data from the alternate branch path rather than from the failover route. Various other apparatuses, systems, and methods are also disclosed.

Abstract translation: 设备可以包括处理器和控制平面，其指导处理器（1）检测到点对多点标签交换路径的初始分支路径的至少一部分已经故障转移到重新加入的故障转移路由 在合并点设备处的初始分支路径和（2）建立与合并点设备处的初始分支路径合并的备用分支路径。 该装置还可以包括网络接口和数据平面，该数据平面使用网络接口经由备用分支路径发送数据，同时数据仍然通过初始分支路径发送，其中在数据平面开始经由备用分支路径发送数据之后 控制平面指示合并点设备从备用分支路径而不是故障转移路由转发数据。 还公开了各种其它装置，系统和方法。
