Network Slicing – A Distinguishing Feature of 5G Wireless |
One of the key innovations in 5G Wireless is advanced Network Slicing capability. This enables flexible and dynamic adaptation of end to end network resources allowing network operators to split the physical infrastructure into multiple logical networks. Each slice is orchestrated according to specific application characteristics. Network Slicing is based on the foundation provided by dynamic topology capabilities of Software Defined Networking (SDN), virtualization capabilities of Network Functions (NFs) augmented by orchestration and network analytics. This presentation covers the overall cloud based structure, architecture, and implementation aspects of Network Slicing. Major advantages over comparatively limited 4G wireless approach and flexibility as compared to Virtual Private Networks (VPNs) are highlighted. How the Radio network and the User Equipment (UE) fit into the overall end to end Network Slicing capabilities is identified. Phased implementation in terms of instantiation, configuration, activation, and assignment of a network slice to the device is covered. How the Network Slice Manager (NSM) allows programmability at three different layers - application, control and data is mentioned. The powerful approach of use of flexible slicing templates consistent with the three standardized 5G offers – enhanced Mobile Broadband (eMBB), massive Machine Type Communication (mMTC), and Ultra Reliable Low Latency Communications (UR-LLC) - is highlighted. |
