1. Towards a single virtualized data path for VPP Zhihong Wang Intel FD.io Mini Summit Seattle 2016

2. Outline Background Features, performance Integration Network Platforms Group 2

3. Background Why virtio ring? Virtual Appliance Virtual Appliance Virtual Appliance vSwitch or vRouter Standard spec. High performance Bypass kernel Share memory based Smart notification Cache friendly Host Kernel Continuously evolving Secure Network Platforms Group 3

4. A single Vhost BESS 2 Vhost in VPP Historically, VPP has a stock Vhost-user VPP Unified PMD for Vhost in DPDK DPDK OVS Desire: A single Vhost Development/optimization convergence Contrail Lower maintenance effort Better usability 1 + 1 + = 1 Lagopus Network Platforms Group 4

5. DPDK Vhost evolution Feature support Reconnect, live migration, offloading, multiqueue Rings, descs, R/W Virtio core Performance optimization: Design + Implementation R/W Vhost core Reaching the maximum throughput for 0.95/1.0 Cache access: Batching, avoid RFO bubbles Virtio 1.1 New ring layout Simple can be harder than complex.
