OVS已经支持基本的HW offload框架,OVS内部的flow表示被转化成基于DPDK rte_flow的描述后通过rte_flow_create() API将流表规则下发到硬件,后续OVS接收到的报文将会被硬件打上flow mark标签,OVS可以迅速地从flow mark索引到相应的flow并执行其action。对于VXLAN或者其他类型的隧道协议,OVS HW offload框架需要将软件data...

当前虚拟交换快路径的硬件卸载有两种实现方式:一种是基于TC Flower接口的卸载,另一种是基于rte_flow接口的卸载。常见的大都基于TC FLower的方式进行硬件卸载。 使用ovs的datapath作为slowpath,默认下发一个miss规则到eswitch中,首包进入,当前没有命中任何表,匹配到默认规则,通过vf-representor被送到eswitch的管理端口也...

(Poll Mode Driver). It preserves the existing north bound APIs (Openflow) and is a drop in replacement for upstream OVS. But the main difference is that OVS-DOCA uses the DOCA-flow api instead of the rte_flow used by DPDK. This allows it to use hardware steering for offloads instead ...
infrastructure. OVS supports all popular tunneling protocols like VXLAN, GRE, Geneve, and STT, and provides advanced features like flow control, QoS, and network slicing. OVS is widely used in OpenStack, Kubernetes, and other container platforms to create and manage virtualized networking ...
using the rte_flow API. - SRv6 Tunnel Protocol * Added support for userspace datapath (only). - Userspace datapath: * Connection tracking now supports extraction of SCTP L4 information. * Implementation of OpenFlow meters is now lockless allowing for better multi-thread scalability. ...

For additional mempool statistics enable CONFIG_RTE_LIBRTE_MEMPOOL_DEBUG while building DPDK. DATAPATH DEBUGGING COMMANDS These commands query and modify datapaths. They are are similar to ovs-dpctl(8) commands. dpif/show has the additional functionality, beyond dpctl/show of printing OpenFlow port ...
