Chapter XXI. OVS Kernel Datapath Offload
Chelsio Unified Wire for Linux 298
Introduction
Open vSwitch is a production quality, multilayer virtual switch licensed under the open source
Apache 2.0 license. It is designed to enable massive network automation through programmatic
extension, while still supporting standard management interfaces and protocols.
Chelsio’s T6/T5 Unified Wire solution can offload OVS datapath flow match entries and action
processing onto Chelsio adapter for hardware acceleration of OVS datapath flow processing.
Chelsio 1/10/25/40/50/100Gb Ethernet controllers and adapters are capable of offloading
OpenFlow and non-OpenFlow network traffic simultaneously, including tunnel handling (e.g.
VXLAN / IPsec), NAT, IP stack (ARP, route lookup, frag tracking, fragment / defragment) and
other kernel functionalities. A high performance, scalable network I/O is delivered by leveraging
built in eSwitch and traffic manager capabilities. In addition, features like traffic classifier, load
balancer
and firewall are supported at port level by all Chelsio adapters.
