Title:
METHOD, DEVICE AND STORAGE MEDIUM FOR CREATION OF BI-DIRECTIONAL SEGMENT ROUTING TUNNEL
Document Type and Number:
WIPO Patent Application WO/2019/141118
Kind Code:
A1
Abstract:
The present disclosure discloses a method, a device and a storage medium for creation of a bi-directional segment routing (SR) tunnel, wherein, the method comprises: during a session establishment process of a first network element and a second network element, deciding by messaging whether or not capability negotiation for creation of a bi-directional SR tunnel is supported; and if creation of an SR tunnel is supported, the first network element sending to the second network element an SR tunnel creation message carrying a bi-directional flag bit, such that the second network element can determine, in accordance with the bi-directional flag bit, whether the tunnel created is a bi-directional tunnel or a unidirectional tunnel.
