Key Concepts and Terminology in 5G Network Slicing

Network slicing in 5G aims to enhance network flexibility by allowing multiple logical networks to coexist on a single physical infrastructure, enabling customized network services for different applications and use cases.

Aggregation is not a key characteristic of 5G network slicing. Isolation, multi-tenancy, and scalability are the primary characteristics that define network slicing in 5G.

Slice orchestration is the process of creating, managing, and controlling network slices throughout their lifecycle. It involves coordinating resources, configuring network elements, and ensuring the proper functioning of each slice.

The Network Slice Manager (NSM) is the central entity responsible for managing and coordinating network slices in a 5G network. It interacts with other network components to create, modify, and terminate slices, ensuring their proper operation and resource allocation.

The primary function of a Slice Controller (SC) in 5G network slicing is to enforce slice policies. It ensures that each slice adheres to its defined parameters, such as bandwidth, latency, and security requirements, by configuring and controlling network resources accordingly.

Temporal isolation is not a type of network slice isolation in 5G. Logical isolation, physical isolation, and resource isolation are the primary isolation mechanisms used to ensure the separation and protection of different network slices.

Slice elasticity refers to the ability of a network slice to adapt its resources and performance characteristics based on changing demands. It allows the slice to scale up or down dynamically to meet the varying requirements of the applications and services running on it.

Simplified network management is not a benefit of using network slicing in 5G. Network slicing introduces additional complexity in terms of managing and coordinating multiple logical networks on a single physical infrastructure.

Network slicing is the process of dividing a physical network into multiple virtual networks, each tailored to specific applications or services. It enables the creation of isolated and customized network environments on a shared infrastructure.

Slice network function is not a key component of a 5G network slice. Slice profile, slice instance, and slice management system are the essential components that define and manage network slices.

Slice profile is the term used to describe the set of parameters and requirements that define a network slice. It includes information such as slice type, bandwidth, latency, security, and isolation requirements.

Management plane slice is not a type of network slice in 5G. Control plane slice, user plane slice, and data plane slice are the primary types of network slices defined in 5G architecture.

Slice instantiation is the process of assigning resources and configuring network elements to create a network slice. It involves allocating bandwidth, configuring network functions, and establishing connectivity between network components to realize the slice according to its defined profile.

Cost and complexity is not a key challenge in implementing network slicing in 5G. Resource management, security and isolation, and standardization and interoperability are the primary challenges that need to be addressed for successful network slicing deployment.

Slice resilience is the term used to describe the ability of a network slice to maintain its performance and functionality even in the presence of failures or disruptions. It ensures that the slice can withstand and recover from network outages, equipment malfunctions, or other adverse conditions.
