05: Additionally, each time an upgrade is performed, the operator will usually upgrade a group of related applications. If done manually can introduce risks such as missed upgrades, wrong versions, difficult rollbacks, and inconsistencies. Therefore, automation is essential due to the large scale of the system.
06: ZTM is a fully automated network management approach, widely adopted in 5G and beyond, enabling self-optimization and self-healing of networks.
07: The paper presents a zero-touch solution for upgrading Cloud-native Functions (CNF) on cloud platforms, automating the rolling upgrade process. Our zero-touch solution for upgrading CNF is only a small part of the ZTM approach; however, it has already brought certain efficiencies.
08: The solution has been implemented in the vOCS system, significantly reducing operational costs, enhancing service continuity, and improving system performance and reliability. |
