Following some recent work to run VXLAN using HW offload, the Napatech OVS offload initiative now explores another important feature: mirror offload. Learn how this enables monitoring without affecting performance of the overall system.
In continuation of his previous blog on the history, vision and challenges of NFV, Daniel Proch now moves on to discuss the solutions that are required to overcome those challenges.
