Have you ever wondered how you are able to connect with your cousin sitting abroad, over calls or via texts? I always fancied what facilitated my communication, and how the signals travel. It was quite later that I knew all of this was done by the means of networking.
Networking can be defined as the practice of transporting and exchanging data between nodes ( it is a physical device, within a network of tools that is efficient in sending and receiving data ) over a shared mode of information system.
Networking encompasses design, construction and also utilising network along with management, maintenance and operations.
As we just saw what networking is, in this blog we shall understand, what is the much talked about Network slicing.
What is Network slicing?
Network Slicing can be defined as a type of functionality that further enables, numerous independent networks to work on a similar physical network, using varied “slices” that hail from the spectrum band. This further allows any enterprise, or organisation to accommodate all kinds of requirements for security, performance and liability on the same network.
Network slicing leverages automation to quickly segment the network and its resources. Network slicing is a cost-efficient, way for enterprises to scale their business.
To be precise, network slicing leverages, Software-defined Networking (SDN), Network Function Virtualization (NFV) and automation as we discussed earlier.
How and why does it matter?
Network slicing makes businesses efficient, in controlling traffic resources on a very particular and more granular level. Every particular slice of traffic can have its own resource requirements, Quality of Service (QoS), security configurations and latency requirements.
For instance, the characteristics of a network slice supporting high-definition streaming video would be different from the slice that has been used to monitor an Internet Of Things (IoT) lighting system.
In non-sliced networks, devices have the access to multiple resources than actually needed ones.
It is of paramount importance:
Network slicing is useful as it acts as a preservative for recourses by deciphering and understanding the context. It further uses cases for each application and appropriately assigns the correct amount of resources.
It is because of core network technology like NFV, Networking slicing is now becoming easier to accomplish over the 5G networks. Enterprises, mobile network operators and even managed service providers are among the beneficiaries of the utilization of network slicing.
How does Network Slicing work?
Network Slicing utilizes virtualization technology to create multiple networks or slices over the top of a single shared network. Each slice contains its own unique latency, security, throughput and also it’s own unique bandwidth characteristics.
The software-defined Networking allows the segmentation to occur by the means of separation in the network control plane, from the packet-handling data plane. Then further the control plane starts creating virtual networks by defining packet handling rules over on the data plane. If explained simply one can try to understand it as a way more comprehensive version of a Virtual Local Area Network (VLAN) for 5G networks.
Similar virtualisation is applied to Radio Access Networks (RANs) which are commonly known as Software-Defined RANs (SD-RANs). Network slicing across an SD-RAN permits network operators to separate traffic physically on varying radio networks. It also allocates pooled resources and combines the resources of multiple networks as per the need.
All these options permit both the service providers and private enterprises to further improve the spectrum efficiency and resource usage way ahead of what the former cellular generations were capable of.
Benefits of Network Slicing for 5G :
There are multiple benefits of network slicing for 5G uses. End-to-end network slicing makes it possible for newer business model innovation and utilisation cases across all verticals and creates new revenue opportunities for communication service providers. It provides service flexibility and also shares the ability to deliver services faster along with higher security, isolation and applicable characteristics to be able to meet the contracted SLA.
Network Slicing enables operators to maximize the return on investments that are made by the means of efficient usage and management of network resources. It also facilitates flexibility in service and also renders the ability to further deliver services at a faster pace along with higher security, isolation and applicable characteristics to be competent enough to meet the contracted SLA.
The procedure of the return on all kinds of network slicing enables the operators to maximise the returns on investment via efficient usage and management of the network resources and also provides discretionary services at scale.
A few of the benefits of enterprises are listed as follows:
1. Be efficient in meeting the needs of enterprises :
With the advent of 5G newer and improved technologies are also flooding the markets and newer business opportunities across all industries. All enterprises and organisations are always on the lookout for more innovative, smart solutions to be able to meet their needs and make their businesses more efficient.
Enterprise users always look for automated business and operational processes starting from ordering the services, activation, delivery and also the de-commissioning of the services. One of the most common expectations is that all enterprises want fast delivery with high-end security. This is facilitated by network slicing.
2. Remote Broadcasting report:
Network Slicing and 5G have the chance and ability to radically change how broadcasters of all sizes transmit live content from remote locations. They benefit from high speeds unarguably to make their work more efficient.
Also, they will benefit from, having smaller crews and the possibility to cover large areas or more work for less. The revenue opportunities also increase for service providers, and comparatively newer business models and also partnerships to explore.
3. Mobile Cloud Gaming Report:
The market for cloud gaming is also growing and evolving at a rapid speed. Gamers in today’s world are ready to pay for better-enhanced gaming experiences. With this the entry to more improvised high-performance games.
In conclusion, we can say that network slicing is important and as seen above there are many benefits of the same. It will be more crucial in future to ensure a better and superior network in the future. It is competent enough to guarantee priority and efficient security levels.
