SOLUTION BRIEF vEPC Acceleration Using Agilio® SmartNICs The virtual Evolved Packet Core (vEPC) is the crux of 3G and 4G utilization. mobile networks used in service provisioning for mobile users. User Equipment (UE) eNodeB/MME S-GW/P-GW Echo Server The main functionality of the vEPC is to act as an interface between the 3G and 4G radio interfaces and public IP networks. VM VM Packet Sink. The vEPC is implemented as virtual network functions (VNFs) Packet Gen. (eNodeB/MME) (SGW/PGW) (PDN) within virtual machines (VMs) running on commercial of-the- shelf (COTS) servers. Netronome Agilio SmartNICs provide a 5X increase in vEPC bandwidth on the same number of CPU Xeon - 2x12 cores Xeon - 2x12 cores Xeon - 2x12 cores Xeon - 2x12 cores cores by using the open vSwitch (OVS) offload and SR-IOV Traditional NIC OVS OVS Traditional NIC Agilio CX Agilio CX technologies.
