Usually, researchers seek expert guidance regarding the enhancement of 5G models and simulation. Our experts are rendering entire research support to scholars and students from all over the world. Now let us see in detail about network slicing.

 

What is Network Slicing?

Network slicing is the mechanism through which a network is built and maintained to meet the user demands. The network is divided into a different logical set of networks for this purpose. The sole purpose of logical networks is to comply with service (QoS and QoE) demands. The logical networks should also so incorporate accurately configured network components that are connected (end to end)

Though there are many other aspects of 5G network architecture, network slicing plays a key role. Its advantages are huge that it takes deep research to understand. We provide technical support from the basics to the advanced level of understanding. Now let us see about the network slicing benefits.

What are some of the benefits of network slicing?

The major function of network slicing is the transformation of the network based on the following criteria

 

  • Abstraction
  • Orchestration
  • Isolation
  • Separation of the components of logical networks from the physical network

Finally, the working efficiency of the whole network is enhanced. The use of advanced technologies in network slicing simulation to enhance 5G network architecture is encouraged these days. Before understanding the deep research studies in network slicing, it is essential to look into its functioning.

 

HOW IS NETWORK SLICING DONE?

Network slicing is done by transforming a holistic network into a group of logical networks in a shared infrastructure. The purposes of every logical network vary with the business for which it is used. Do you know the major aspects of a logical network?

 

  • Proper configuration
  • End to end connection
  • Consisting of all resources for network functioning

The provisions of network slicing derive more interested researchers into the field. We have been providing research reference data from authentic sources, ensuring the researcher’s freedom to delve deep into their network slicing simulation topic. So you can approach us to get access to benchmark references for your research. Now let us look into the two types of network slicing.

As we have been in the field of 5G research guidance since its introduction, we are very well qualified and trained to guide you throughout your research journey. Now latest understand more about the various levels in network slicing.

 

DIFFERENT LEVELS OF NETWORK SLICING

 

  • Network-level: all network infrastructure slicing
  • Infrastructure level: using visualization methods to slice the elements of physical networks (processors, antennas, memory, and BSs)
  • Spectrum level: also called link virtualization. Slicing can be done on different components like frequency, space, and time multiplexing (or overlaid access)

Simulation tools are used to identify the problems in network slicing. We have used many simulators and have gained huge experience in handling these tools. So you can talk to our experts about any doubts regarding all kinds of simulators.

IMPORTANT LIMITATIONS OF NETWORK SLICING

A researcher’s work shall be to devise novel methods to overcome the functioning constraints of network slicing, as mentioned below.

 

Quality of service:

QoS requirements are compromised for a reduction in complexity, which poses constraints on use case flexibility. Management and implementation costs are also the limitations.

 

Supportive to various types of devices and traffic:

Microburst data type is created out of the maths internet of things applications. Increased reliability and bandwidth are necessary for AR and video analytics

 

Reliability in wireless infrastructure:

The questions of scalability, mobility, and flexibility come into play in sensitive real-world applications. So in most cases, wired networks are preferred

 

Issues of scalability in the future:

Higher quality by avoiding congestion is insured by over-provisioning or provisioning based on peak traffic. But a significant network update demands the inclusion of unpredictable scenarios of traffic and novel use cases

 

Limitations in mobility:

Mobility management is a huge limitation on network slicing. Access point handovers are less reliable in present-day wireless networks.

Already in our research journey, we have encountered many research issues that arose as a result of these limitations. The reputation that we earned among research scholars worldwide is primarily due to how we devised reliable solutions to such issues and limitations. Now let us see some more about the challenges in network slicing.

 

WHAT ARE 5G NETWORK SLICING CHALLENGES?

5G networks are actually logical networks deployed on common physical infrastructure. Various services are provided by a dedicated network that is kept stable. The reason behind such work is the complete separation of the end-user data plane and control plane. Understanding the 5G network slicing is not a big deal while its implementation is. The following are the common 5G network slicing challenges.
