Abstract
Explicit signaling mechanisms facilitate automatic stitching for both packet and non-packet label switched paths (LSPs). Extensions to resource reservation protocol signaling are utilized to include explicit signaling mechanisms that setup and maintain LSPs. An inter-domain LSP may be created by automatically stitching independent LSP segments within separate domains. Stitching the intra-domain LSP segments creates an end-to-end LSP in the data plane with continuous label swapping across the different domains. An intra-domain LSP may be created by automatically stitching independent LSP segment within a single domain. A network device, such as a router, at an ingress of an LSP segment utilizes the signaling extensions to notify a network device at an egress of the LSP segment to prepare for a stitching procedure. In return, the egress network device utilizes the signaling extensions to inform the ingress network device whether the LSP segment is ready for the stitching procedure.
