Abstract
A segment routing-based MPLS packet forwarding method and a device thereof are proposed. The method includes establishing a forwarding path in a Multiple Protocol Label Switching (MPLS) network by receiving a packet, checking whether processing of a size of a label stack related to each node included in the forwarding path is available or not in each node, generating a first MPLS packet by adding an MPLS header having the label stack to the packet in response to availability of the processing, and generating a second MPLS packet by adding an extension header having the label stack and by adding an MPLS header having a part of the label stack allocated according to the label stack size processable by each node to the packet in response to unavailability of the processing.
