Label switched path (LSP) stitching without session crossing domains
Methods and apparatus are provided for stitching and/or nesting label-switched path (LSP) segments for creating an end-to-end (E2E) LSP without running a Resource Reservation Protocol-Traffic Engineering (RSVP-TE) session over an inter-domain link. The present disclosure is applicable to various types of domains including, but not limited to, autonomous system (AS) domains and area domains. Advantages of the disclosed embodiments include providing an easy and efficient method for creating E2E LSP, simplifying network operations, and reducing the cost of network Operations, Administration, and Maintenance (OAM).
