FCAPS refers to a framework used in network management that encompasses five key areas: Fault Management, Configuration Management, Accounting Management, Performance Management, and Security Management. This skill involves the systematic approach to monitoring and managing network resources to ensure optimal performance and reliability. Knowledge of FCAPS is utilized to identify and resolve network issues, maintain system configurations, track resource usage, assess performance metrics, and implement security measures to protect network integrity.

Network Functions Virtualization refers to the process of decoupling network functions from dedicated hardware appliances, allowing them to run as software on virtualized infrastructure. This skill involves understanding the architecture and deployment of virtualized network services, which enhances flexibility, scalability, and resource efficiency in network management. Knowledge of Network Functions Virtualization is used to implement and manage virtualized network functions such as firewalls, load balancers, and routers, facilitating dynamic network configurations and reducing operational costs.

Network provisioning is the process of setting up and configuring network devices and services to ensure proper communication and data transmission between devices. It requires a specialized skillset and involves tasks such as assigning IP addresses, configuring routers and switches, setting up VLANs, and ensuring security protocols are in place. Network provisioning is critical for organizations to ensure the reliability and efficiency of their network infrastructure.

OpenDaylight is an open-source software for networking that provides a platform for creating and managing virtualized networks. It is designed to enable software-defined networking (SDN) and network functions virtualization (NFV) in the modern data center. OpenDaylight is a project supported by the Linux Foundation and its source code is available for free under the Apache license. Those with knowledge in OpenDaylight are often network engineers or system administrators who specialize in SDN and NFV environments.

OpenNMS is a network management platform that provides monitoring, event management, and service assurance capabilities for IT and telecommunications networks. It is an open-source solution that can be customized to meet specific network management needs. It can monitor network devices, servers, applications, and services, and alert administrators when problems arise. OpenNMS can also generate reports and provide data analytics to help identify trends, troubleshoot issues, and optimize network performance.
