The Netronome® Agilio® solution is able to achieve higher performance per vEPC VNF (P-GW and S-GW) while delivering significant savings in the number of CPU cores used for network processing by implementing transparent Open vSwitch datapath offload. The performance advantage and savings are further enhanced when VXLAN and multiple ACL rules per VM are applied to simulate a secure multi-tenant environment in this proof of concept. Please refer to the Virtual EPC White Paper for more details.
Netronome has partnered with Tieto to deliver a vEPC proof of concept implementation that can be experienced through the vEPC test drive section. The test setup utilizes the MME, P-GW and S-GW software and the Tieto IP (TIP) stack from Tieto and is installed on Dell servers where the Agilio CX SmartNIC are installed. OVS based L2 and L3 forwarding rules between the VMs are offloaded to the Agilio CX solution. For multi-tenant and secure environments, VXLAN and security rules are applied to the VMs. Please refer to the Virtual EPC White Paper for more details.
vEPC consists of mobility management entity (MME), packet gateway (P-GW) and serving gateway (S-GW)) which can run in virtual machine (VM). The virtualized functions allocated to VMs are called a virtual network functions (VNFs). Each VNF in a vEPC network is isolated from the other VNFs, and have their own performance requirements. However, all the VNFs implemented in a single or multiple servers must interconnect in order to forward packets between them correctly. In multi-tenant and secure environments, technologies such as VXLAN and security policies per VNF becomes important. Please refer to the Virtual EPC Whitepaper for more details.
