Network slicing is a method of creating multiple unique logical and virtualized networks over a common multi-domain infrastructure.
Another way of looking at it, Network slicing overlays multiple virtual networks on top of a shared network. Each slice of the network can have its own logical topology, security rules and performance characteristics — within the limits imposed by the underlying physical networks.
Different slices can be dedicated to different purposes, such as ensuring a specific application or service gets priority access to capacity and delivery or isolating traffic for specific users or device classes. Slicing networks enables the network operator to maximize the use of network resources and service flexibility.
Network slicing is a key feature of 5G.
5G network slicing is a network architecture that enables the multiplexing of virtualized and independent logical networks on the same physical network infrastructure. Each network slice is an isolated end-to-end network tailored to fulfil diverse requirements requested by a particular application.
The benefits of network slicing are considerable, such as:
- It helps network operators in reducing expenses (OPEX) and capital expenditure (CAPEX).
- It vastly improves operational efficiency and time to market for the delivery of 5G network services.
- A single network can be used to offer various services based on the requirements of the user and various use cases.
- Network operators can allocate the right amount of required resources as per network slice. Hence, it helps in the effective and efficient utilization of resources. For example, one network slice can be designed to deliver low latency & low data rate while the other network slice can be configured to deliver high throughput.
- It overcomes all the drawbacks of “DiffServ” which is the most popular QoS solution.
