What are your XDP use-cases? ● Discuss what XDP could be used for? 20/23 XDP – eXpress Data Path
XDP use-case: Bridge + Virtual machines ● ● ● Use-case: delivery into virtual machines (VM) ● Depend on extending e.g. vhost-net with XDP compatible xmit function Combine L2-bridge with VM ports ● ● ● L2-bridge is a known technology VMs have a way of communicating and discovery of each-other (eBPF could do arbitrary matching of VM) ● save that idea for another time... 21/23 XDP – eXpress Data Path
