Summary:With the increase of business scenarios in 5G communication, the 5G bearer network puts forward higher requirements in terms of bandwidth, time delay, pan-connection and reliability, and also puts forward extremely high requirements for network-level protection technology. The introduction of segment routing tunnel technology, the innovative establishment of 5G efficient carrying network. Due to the working mechanism of the SR tunnel, the traditional signal degradation protection technology is no longer suitable. This paper proposes a protection scheme for the existence of signal degradation in the Segment Routing - Best Effort tunnel through the OAM message transmission alarm. The signal degradation detection and ISIS protocol, can realize link protection, in order to further improve the user experience, design method trigger TI-LFA protection business protection reverse, improve the reliability and viability of 5G carrying network, confirmed that the scheme has the ability to detect and protect the business flow signal, can be protected in the east-west eX2 traffic business.
