Abstract:

This paper proposes a hybrid access method for multi-access points and multi-cloud pools based on 5G technology, by constructing a redundant active-standby network architecture and combining the active-standby switching mechanism of wired links with software-defined networking in a wide area network (SD-WAN) superimposed 5G slicing, it solves the hybrid cloud access problems caused by the replacement of old and new systems and the requirement for business continuity. Focusing on sub-second switching between primary and backup links, the method realizes efficient connection between multi-access points and multi-cloud pools through a hierarchical service guarantee mechanism. Verified by practical tests, on the premise of ensuring business continuity, this method can significantly reduce network management complexity and operational costs, and may serve as an effective access solution for high-reliability network scenarios..

Key words: multi-cloud pool, hybrid access, 5G slicing, SD-WAN
