OVS-CAB can handle data traffic at a high line rate, while keeping host CPU usage low by offloading rule lookup functions to a hardware-based Smart Network Interface Card (Smart-NIC). Moreover, OVS-CAB achieves a high data plane hit rate and keeps hardware memory space usage low by ...
offload就是ovs转发时用硬件的功能,少耗费host的cpu,这就要求虚拟机和硬件之间能直接交互报文,报文就不用经过host的cpu,ovs只负责给硬件下发转发规则。 硬件资源是有限的,ovs不可能事先把所有转发规则下给硬件,这就要求有一种触发机制,一个报文来了触发ovs给硬件下转发规则,后续报文由硬件转发不再经过ovs, 既然报...
QOS:Quality of Service,服务质量,指一个网络能够利用各种基础技术,为指定的网络通信提供更好的服务能力, 是网络的一种安全机制, 是用来解决网络延迟和阻塞等问题的一种技术。 NIC:Network Interface Card,网卡,网卡是局域网中最基本的部件之一,它是连接计算机与网络的硬件设备。 PCI:Peripheral Component Interconnect,...
flow:需要匹配的报文的提取值,中途可以邻居修改,但是最终是保持报文原样的,将来用来作为megaflow的value。 wc:通配符,报文起始查找时是通配所有的,在整个报文匹配中使用同一个wc,命中一个规则就将该规则对应的掩码unwildcard,表示报文需要匹配这些域,当报文通过goto和resubmit动作转移到另外一个table时,依然会使用原来的...
To set up SR-IOV: Choose the desired card. The example below shows a dual-ported ConnectX-5 card (device ID 0x1017) anda single SR-IOV VF(Virtual Function, device ID 0x1018). In SR-IOV terms, the card itself is referred to as the PF (Physical Function). ...

Hi! I must first say i am no seasoned network card virtual functions user but generally feel virtual-functions-and-co would be important thing tomorrow so for no very particular reason i try them out in different combinations. As staring point i had working setup like this with pve v. 8.2...
