5G V Flashcards
What is network management
processes for administering, managing, and operating a data network
What are the network management functions?
Element Manager (EM): management for a Network Function (NF)
Managing Entity (ME): Makes decisions for different management operations
What is a Management Object?
an abstract representation of network resources that are managed
Please describe OAM procedures (Operations, Administration & Maintenance)
Provisioning: Introducing of new services, network functions or networks
Troubleshooting: following a failure, finding the specific issues that caused the failure
What functions are covered by FCAPS?
Fault Management: local handling for most of the network alarms and faults
Configuration Management: distribution of functioning policies / subscription profiles
Accounting: integrated local and remote accounting
Performance: local handling of network performance
Security: local handling / escalation when needed
Please describe fault management (detection, localization, reporting)
Live migration: moving the virtual container from one physical host to the other without interrupting the communication with the client
Cold migration: moving the virtual container from one physical host requiring a power off of the instance before the migration initiates
Please describe the hot standby mechanism (state sharing)
Each component has always updated information on all the users
Each component logic is unaware that other components of the same type are in the system
The state is not lost in case the components fail
Please describe a monitoring system
provides the information that network management needs to determine, in real time, whether a network is running optimally
Please describe performance management
a proactive solution that helps identify and reduce instances of bottlenecks
Please describe security management
Providing the proper security functionality within the dynamic software-based network environment, as automated as possible
Please describe device/connectivity management
Providing the appropriate connectivity management for a massive number of devices
Please describe the edge network management
local handling of local network through edge node that has the same specification as the central system
Please enumerate the one-touch deployment operations and functionality impacted (through one deployment the customer will have everything)
Local Private 5G Network
i. Planning and deployment of base stations
ii. Integration with local devices
Local Edge Network
i. Automatic device management
ii. Customized Private Local Environment
Central Node
i. Proving automatic remote management
Please describe the automation advancements
Ensuring that software defined networks reach the better reliability than physical networks while scaling to new dimensions through automation
What are the features which differentiate a private network and a carrier-grade one?
Wide area mobility
Integration with transport and core network
Network management
End-to-End Quality of Experience
Security
Scalability
Seamless integration with other communications systems (ex. 3GPP)
