Network slicing enables the creation of virtual, isolated networks tailored to specific service requirements within a shared physical infrastructure.

IEEE Access · 2020

Key Findings

01Network slicing allows for the transition from infrastructure-centric to service-centric network management.
02A detailed taxonomy of network slicing can be established based on various parameters including design principles, enablers, resource levels, and security.
03Specific requirements for network slicing are crucial for enabling diverse smart services.

Application

Design takeaway

How to apply

When conceptualizing a multi-service platform, model how different services (e.g., real-time control, data analytics, video streaming) could be assigned to distinct network slices with unique Quality of Service (QoS) parameters.

Project actions

01When modelling a complex system, consider how different user groups or functionalities might benefit from dedicated, virtualized resources.
02Use the taxonomy provided to categorize the different aspects of your proposed system's network requirements.

Method & Evidence

AimTo develop a comprehensive taxonomy and identify key requirements for network slicing to effectively support diverse 5G smart services.

MethodLiterature review and conceptual framework development.

ProcedureThe research involved reviewing existing literature on network slicing, identifying key design principles, enablers, resource levels, service chaining schemes, physical infrastructures, and security aspects. Based on this, a taxonomy was devised, and critical requirements for enabling smart services were discussed.

ContextTelecommunications, 5G networks, Internet of Things (IoT) applications.

Variables

IV["Network slicing parameters (e.g., resource allocation, isolation levels, QoS settings)"]

DV["Service performance metrics (e.g., latency, throughput, reliability)","Resource utilization efficiency"]

CV["Underlying physical network infrastructure","Types of services being supported"]

Strengths & Limitations

Strengths

+Provides a comprehensive taxonomy for understanding network slicing.
+Identifies key requirements for enabling diverse smart services.

Limitations

The practical implementation of network slicing can be complex, involving significant infrastructure changes and sophisticated management systems that may not be feasible for all design projects.

Reliability & validity

The reliability of the findings is based on a comprehensive review of existing research. Validity is supported by the logical development of the taxonomy and the identification of key requirements, though empirical validation of specific slicing strategies would enhance it.

Think critically

How might the security implications of network slicing, such as potential vulnerabilities at the slice management layer, impact the overall reliability and trustworthiness of a system designed using this approach?

Design Principles

"Virtualize and partition network resources to create bespoke network environments for distinct service requirements."

This approach allows for efficient resource allocation and guarantees performance for diverse applications, from low-latency gaming to high-bandwidth video streaming. Designers can leverage this concept to conceptualize and model complex systems that must simultaneously support vastly different user needs.

What This Means for Your Design

Imagine a highway where different lanes are reserved for different types of vehicles – some for fast sports cars, some for slow trucks, and some for emergency vehicles. Network slicing is like that for data, creating special 'lanes' on the internet for different online services so they work best.

How to use in your project

1.Reference this paper when discussing the conceptualization of a multi-service system and how different services will be supported.
2.Use the taxonomy to structure the analysis of network requirements for different user scenarios in your design project.

Paragraph starter

Network slicing, as explored by Khan et al. (2020), presents a critical paradigm for designing modern communication systems. This approach allows for the creation of multiple virtual networks on a shared physical infrastructure, each tailored to specific service requirements. By categorizing network slicing through a comprehensive taxonomy, designers can better understand how to allocate resources and ensure quality of service for diverse applications, moving towards a network-as-a-service model.
