In telecom, “slicing” refers to the concept of network slicing, a key feature introduced in 5G (fifth-generation) mobile networks. Network slicing allows the creation of multiple virtual networks on a shared physical infrastructure, enabling the customization of network resources to meet the diverse requirements of different use cases and applications.
Network Slicing in Telecom:
- Definition:
- Network slicing is a technique in 5G networks that involves the creation of multiple independent and customized virtual networks, known as slices, on a common physical infrastructure. Each network slice is tailored to meet specific requirements, such as performance, latency, and capacity, for diverse use cases.
- Customization for Different Use Cases:
- Network slicing enables the customization of network resources to cater to the distinct needs of various use cases and applications. Different slices can coexist on the same infrastructure while maintaining isolation and dedicated resources.
- Key Characteristics:
- Each network slice possesses its own set of characteristics, including specific Quality of Service (QoS) parameters, network functions, and service capabilities. Slices are designed to accommodate the demands of applications ranging from enhanced mobile broadband (eMBB) to massive machine-type communication (mMTC) and ultra-reliable low-latency communication (URLLC).
- Isolation and Independence:
- Network slices are logically isolated from each other, ensuring independence and preventing interference. This allows the coexistence of diverse services and applications with distinct performance requirements on a shared physical infrastructure.
- Resource Allocation:
- Network slicing involves the allocation of resources such as bandwidth, processing capacity, and radio spectrum to each slice based on its specific requirements. This dynamic resource allocation enhances network efficiency and optimizes resource utilization.
- Service-Oriented Architecture:
- The architecture of network slicing is service-oriented, aligning with the demands of specific services or applications. It allows operators to offer tailored connectivity solutions to different industries, including healthcare, manufacturing, automotive, and more.
- End-to-End Customization:
- Network slicing extends beyond radio access and encompasses end-to-end network customization. This includes core network functions, transport networks, and service-specific configurations, ensuring a seamless and optimized experience for users and applications.
- Dynamic Scaling:
- Network slicing facilitates dynamic scaling of resources based on the changing demands of applications. This adaptability allows for efficient resource utilization during periods of varying network traffic or diverse service requirements.
- Orchestration and Management:
- Orchestration and management systems are essential components of network slicing. They handle the creation, modification, and removal of slices dynamically, responding to the evolving needs of services and applications.
- Service Innovation:
- Network slicing fosters service innovation by providing a flexible and adaptable infrastructure. It enables the rapid deployment of new services and applications, encouraging experimentation and the development of diverse use cases.
In summary, network slicing in telecom, particularly in 5G networks, involves the creation of customized and isolated virtual networks to accommodate the specific requirements of diverse use cases and applications. It offers a flexible and service-oriented approach to network design, allowing operators to optimize resource utilization and deliver tailored connectivity solutions.
