Network slicing — which uses software-defined networking (SDN) and network functions virtualization (NFV) — is widely seen as one of the keys to making 5G networking a reality. Thanks to the concept of network slicing, the 5G network architecture will be able to be partitioned on demand to accommodate various use cases. In the 5G mobile future network slicing will permit operators to design, deploy, and customize these network slices atop a common network infrastructure.
Network slicing has become a common phrase in the 5G discussion, but what is dynamic network slicing? It’s defined as the ability to orchestrate specific capabilities across different points of the network.
Dynamic Network Slicing Overview
The goal behind dynamic network slicing is to optimize 5G networks so that they efficiently address all use cases. It allows operators to design, deploy, customize, and optimize the various network slices that are running on the common network infrastructure. Beyond its reliance on SDN and NFV, it also depends on end-to-end orchestration and analytics.
Vendors use the term dynamic network slicing because operators will be able to dole out these network slices quickly and on demand. With this type of network slicing, operators can quickly establish unique deployments, architecture types, and performance thresholds for individual use cases or service groups.
Dynamic Network Slicing in 5G
The dynamic network slicing concept will be particularly advantageous in the era of 5G, permitting dynamic end-to-end network partitioning — from the Radio Access Network (RAN) to the transport, to the core. It will allow 5G operators to assemble unique deployments and architectures for each business model, making entirely new use cases and business models possible.
“We envision a scenario where an operator could tailor the network based upon the traffic pattern they see in any environment,” says Jason Elliott, 5G market development manager at Nokia.
Operators will be able to use these slices to support 5G’s extremely diverse and extreme requirements for bandwidth, throughput, latency, and availability, opening up the future to popular use cases such as the Internet of Things (IoT), smart cities, remote medicine, robotics, and connected cars.
The Future of Dynamic Network Slicing
Dynamic network slicing is poised to enable the optimized delivery of any service to a wide variety of users, machines, industries, and verticals. Service providers will then be positioned to generate new revenue and maximize the value of their 5G investment.
