User Plane Function(UPF)

The User Plane Function (UPF) represents the data plane evolution of a Control and User Plane Separation (CUPS) strategy, which is a fundamental component of the 3GPP 5G core network(5GC).

The UPF plays the most critical role in the process of data transfer. It provides the interconnect point between the mobile infrastructure and the Data Network (DN), i.e. encapsulation and decapsulation of GTP-U.

Perfect compatibility with third-party core network elements
5GC UPF Multi-Gbps support: 10GB/25GB/40GB/100GB
Enabled for centralized or distributed data centers
 
Highly scalable 
Enable to deploy on Cloud Platform such as AWS and Azure
High performance, low cost solution
Single instance throughput is up to 100Gbps
IPLOOK's Most Scalable, High Performance UPF
The IPLOOK UPF has been designed to be distributed and virtualized in 5G and offering better that 4G EPC which was designed to be more centralized in the mobile core network and running on COTS server. UPF  can be co-located in the new emerging cloud edge data centers.
 Data transfer process in 5GC  though UPF:
Firstly, the data is sent by an terminal equipment, which will be transmitted over a wireless channel to gNodeB. Then, the gNodeB encapsulates the user data into GPRS Tunnelling Protocol for the user plane (GTP-U) packets. Here comes the most important part, the User Plane Function(UPF) receives users’ data from N3 interface and then sends them to the DN.
IPLOOK‘s Standalone UPF within its 5G Core Network(5GC) enables serving both 4G and 5G Radio Access Networks(RANs). Single 5GC UPF instance throughput is up to 100Gbps.

5G Core Network(5GC)
The 5G Core Network(5GC) adopts a separate control and forwarding architecture, which enables independent mobility management and session management.

Multiple sessions can be established and managed simultaneously by different user-plane network elements and multiple control-plane network elements, enabling parallel operation of local and remote traffic.
