Network slicing

Definition

Network slicing is a technology that allows multiple virtual networks to be created on a shared physical infrastructure, enabling customized connectivity for different applications or services. This approach makes it possible to allocate specific resources and optimize performance for various user needs, like IoT devices or high-speed mobile broadband, ensuring that each slice operates independently and meets its unique requirements.

5 Must Know Facts For Your Next Test

Review Questions

• How does network slicing enhance the functionality of 5G networks compared to previous generations?
  • Network slicing significantly enhances the functionality of 5G networks by allowing the creation of multiple virtual networks on a single physical infrastructure. This means that different applications can have tailored connectivity solutions, such as low latency for gaming or high bandwidth for streaming. This customization wasn't possible in earlier generations, which relied on a more generalized approach to network resources.
• Discuss the role of virtualization in enabling network slicing and how this impacts overall network efficiency.
  • Virtualization plays a crucial role in enabling network slicing by allowing multiple virtual instances of network resources to operate independently on shared physical hardware. This means that service providers can allocate resources dynamically based on demand without needing to invest in separate physical infrastructures. The result is improved overall network efficiency, as operators can better utilize existing resources while also quickly responding to changing service demands.
• Evaluate the implications of network slicing on industries reliant on edge computing and how it transforms service delivery.
  • Network slicing has profound implications for industries reliant on edge computing as it enables customized connectivity solutions that are optimized for specific use cases. For example, in smart manufacturing, a dedicated slice can provide low-latency communication needed for real-time monitoring and automation. This transformation leads to enhanced service delivery, allowing businesses to operate more efficiently while also catering to emerging technologies like IoT, thereby unlocking new business models and opportunities.
