Understanding Telecom Network Slicing

Last updated: 23 Nov 2023

Modern technologies and services are constantly emerging, making the technology landscape ever-evolving. For businesses looking to thrive in this digital world, staying updated on these technologies will help you make strategic decisions on operating your business. One promising technology in the telecom space is network slicing—a groundbreaking innovation that has the potential to reshape the way businesses access telecom services.

What is Network Slicing?

It is the dynamic segmentation of a single physical network into multiple virtual networks. These individual “slices” are tailored to meet the specific requirements of different services and applications. 

On the other hand, often used by many businesses, traditional networking involves creating a single network that serves all users and applications. Its limitations can cause inefficiencies and excessive costs—requiring overprovision of resources to ensure that all users and applications have the needed performance and reliability. 

Network slicing addresses this challenge by creating dedicated networks for each customer or application, enabling efficient allocation of resources, and providing a better user experience. Businesses can access highly specialized and efficient telecom services without significant infrastructure investments. 

Core Components of Network Slicing 

  1. Virtualization and SDN (Software-Defined Networking): Virtualization and SDN enable network slicing by allowing operators to create and manage multiple isolated networks on top of a single physical network. Each slice can be configured with its own set of resources, such as bandwidth, latency, and security policies. 
  2. 2.Slicing Types: Radio, Transport, and Core: 
  • Radio Slicing: It is used for customizing wireless access to accommodate different services with varying bandwidth, latency, and reliability requirements. 
  • Transport Slicing: It tailors the middle network layer that enables allocating specific network resources and paths to slices to handle data traffic according to its unique requirements.  
  • Core Slicing: Core slicing occurs at the network’s innermost layer, ensuring that the traffic from different slices is isolated and efficiently routed through the core network. It is a crucial factor in maintaining the security, isolation, and quality of service for each slice.

Network Slicing Benefits

Enhanced Service Customization 

A one-size-fits-all solution doesn’t work for every business anymore. Network slicing promotes a customized network environment specifically tailored to your business needs. That said, the customization opportunity is limitless. 

  • Dynamic and On-Demand: Network slices can easily adapt to business requirements changes. Businesses can scale their network up or down as needed without overprovisioning resources—offering significant cost savings for businesses with fluctuating bandwidth needs.  
  • Resource Optimization: It allows the allocation of precise resources to each slice based on its specific needs—making the most of your network infrastructure and significantly reducing several investments in upgraded infrastructure. 
  • Isolation and Security: It enhances security by providing logical isolation between slices. Even if one slice experiences a security breach, the impact is contained within that slice and doesn’t affect your other network services. This isolation helps safeguard your critical data by providing an extra layer of protection. 

Improved Quality of Service (QoS) 

Network slicing ensures consistent and reliable connectivity with reduced latency and packet loss, crucial for applications demanding real-time data transfer. 

  • Improved Performance: Having customized networks allows you to employ specific performance levels for every application following the unique parameters of your business’s specific needs. Dedicated network resources and setting up stringent QoS parameters ensure applications receive the necessary bandwidth, low latency, and minimal packet loss to function, guaranteeing optimal performance, especially for critical applications. 
  • Increased Reliability: Each slice operates independently, so the others remain unaffected if one slice faces an issue. This isolation improves the overall stability of your network, ensuring consistent and dependable service delivery. 

Future-Proofing Telecom Infrastructure 

  • Adaptability to Emerging Technologies: Telecom technologies are constantly evolving. Network slicing allows your business to still be able to utilize your existing infrastructure while seamlessly adapting to change. Emerging technologies like 5G and 6G, advancements in AI, or the explosion of big data, a future-proof infrastructure gives you the flexibility to integrate these technologies into your operations, keeping you at the forefront of your industry. 
  • Continuous Innovation: Network slicing offers easy adaptability, creating a telecom environment that can evolve alongside technological advancements. This commitment to progress helps keep your business ahead of the competition and promotes a dynamic, innovative work culture. 
  • Long-term Cost Savings: While implementing network slicing requires an upfront investment, the long-term financial rewards are significant. By preparing for the future now, you can avoid continuous upgrades’ costly and disruptive process.  
  • Support for Internet of Things (IoT) and Edge Computing: IoT and edge computing are revolutionizing business operations, and network slicing provides the robust, reliable connectivity they need to function effectively. Whether you’re processing data in real time at the edge or connecting a myriad of IoT devices, network slicing ensures your infrastructure is ready to fully leverage these transformative technologies. 

Choosing the Right Partner

Network slicing transforms how businesses function optimally, ultimately improving efficiency and performance. Choosing the right partner to help implement this solution is crucial, especially for SMBs with minimal knowledge and experience in deploying this process. Working with a Managed Service Provider (MSP) is ideal, as they can provide the necessary expertise, resources, and tools to make network slicing a reality. 

When choosing an MSP, there are a few key factors to consider:

  • Look for an MSP with a proven track record of implementing network slicing. 
  • Ensure the MSP can scale services as your business grows and changes. 
  • Security is paramount. Choose an MSP with robust security protocols in place. 
  • While investing in network slicing offers long-term savings, consider an MSP that offers competitive pricing.
