    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.

    Abstract: The present disclosure relates generally to a communication system, and more particularly, to a method for time-deterministic packet forwarding that guarantees a maximum and minimum latency requirement of a service, the method including: receiving latency information of links and nodes on a path, and buffer resource information of the nodes; calculating, on the basis of the buffer resource information of the last node, local latency budgets that the other nodes need to guarantee; performing control so that the nodes transmit a packet on the basis of the local latency budgets; and finally guaranteeing, by the last node, a residual latency budget remaining after the nodes transmit the packet within the local latency budgets.

    Abstract: In a switching system using an N+1 switch redundancy method, a backplane connects a plurality of switch cards that are mounted in a half-slot of an upper end portion and a lower end portion of the center of a chassis and a plurality of line cards that are mounted in the half-slot of the upper end portion and the lower end portion of the chassis at both sides of the plurality of switch cards. In this case, in each line card and each switch card, a line card and a switch card of the same position are connected in the upper end portion or the lower end portion of the chassis using some connector groups, and a line card and a switch card that are disposed at the upper end portion or the lower end portion of the chassis are crossed and connected using the remaining connector groups.
