In the digital era, communications service providers (CSPs) are undergoing a technological evolution, and network virtualization is playing a key role—in particular, network functions virtualization (NFV). NFV offers reduced time to market, agility, innovation, an open ecosystem to avoid vendor lock-in, and future CAPEX and OPEX reduction. However, operational transformation can introduce challenges to reliability and performance, too.
By decoupling software and hardware and introducing a virtualization layer, the new multi-layer environment can potentially bring lower reliability, security risks, interoperability issues, difficulties in fault demarcation, and the need for new skills and processes.
A new Huawei white paper discusses the need for a new generation of service assurance solutions. The white paper makes the case that CSPs deploying virtualized infrastructures will need to enhance their current reactive fault-management systems and introduce smart maintenance capabilities. The next era of network management will automate the detection and correction of issues through “smart” or artificial intelligence technologies.
- Unified monitoring
- Alarm correlation
- Automated root cause analysis
- Closed-loop mechanisms
- Fault management capabilities in multi-vendor environments
- Predictive network analytics
- Automated and seamless software upgrades
- Proactive maintenance and continuous improvement
NFV is introducing new challenges into networks, and new capabilities and strategies are necessary in the operational transformation journey. The white paper closes with the suggestion that CSPs focus on enhancing the current re-active maintenance capabilities, as well as proactive maintenance to detect and predict network failures quickly and gradually introduce smart systems to automate network operations.
