Abstract: The present disclosure discloses a method, device and storage medium for creating a bi-directional segment routing (SR) tunnel, the method includes: carrying out capability negotiation for whether to support creation of a bi-directional SR tunnel by messaging during a process in which a first network element establishes a session with a second network element; and if support, sending, by the first network element, an SR tunnel create message carrying a bi-directional flag bit to the second network element so that the second network element is capable of determining, in accordance with the bi-directional flag bit, whether a bi-directional tunnel or a unidirectional tunnel is to be created.

Abstract: A method and a device for processing a packet by using a unified SR label stack, relating to the field of PTN. The method includes: allocating, according to a type of a forwarding plane, a compatibility indicator indicating that a unified U-SRH is carried, for a service packet entering the forwarding plane; adding an SR label stack, the U-SRH and the compatibility indicator to the service packet to obtain an extended packet; and processing and forwarding the extended packet in the forwarding plane according to the SR label stack, the U-SRH and the compatibility indicator. According to embodiments of the present disclosure, the unified SR label stack is used to simplify an application of SR technology in different forwarding planes, and uniformity of SR encapsulation format is enhanced.

Abstract: Provided is a method for creating an inter-domain bidirectional tunnel. The method includes: receiving, by a node, a path creation message sent by a path computation element, the path creation message including mapping path information for creating an inter-domain label switched path (LSP), and bidirectional tunnel instruction information, and obtaining, by the node, an actual transmission path, which is used for data transmission between intra-domain or inter-domain nodes, based on the mapping path information and the bidirectional tunnel instruction information. The present disclosure further provides a communication method, a communication device, and a computer-readable storage medium.
