Acceleration Software for Networking

FPGA Acceleration for Open vSwitch (OVS) Applications

Arrive’s Acceleration Software for OVS applications is a Switching/Routing acceleration solution for Cloud Computing and NFV applications using FPGA architecture. It is best suited in a Smart-NIC form, and can be used to offload the CPU workload and increase performance for multiple functions, including L2 Switching, L3 Routing, QoS, overlay network protocols (VXLAN, NGVRE) and many others.  It can support up to 400Gbps throughput and support millions of flows.  It can be used in many applications such as Open vSwitch (OVS), vBNG/vBRAS, and vRouter/vPE.  It also supports P4 programming language that can increase the flexibility and provide more visibility for network users.

Arrive’s Acceleration Software for OVS applications can be combined with Arrive’s IPSec and SSL/TLS Acceleration Software to add security and cryptography features to provide full secured networking solutions.
