In today’s world, where networks are becoming increasingly dynamic and complex, the traditional method of manual configuration and operation can no longer keep pace with the growing demands for advanced services and the rapid speed of change. The move toward network autonomy is no longer just an option - it is becoming an inevitable direction of evolution for the entire industry. With an eye toward the realization of Intent-Based Networking, we will discuss the roles OSS(Operation Support Systems) should play in the future and how it needs to evolve. Furthermore, using Comarch’s OSS solutions as a case study, we will provide concrete examples of initiatives toward building autonomous networks and current levels of maturity. In addition, we will explore how cutting-edge technologies such as AI/ML are being integrated into Comarch OSS in areas such as intent interpretation, anomaly detection, and automated optimization - together envisioning the future of autonomous networking.
