In conjunction with the release of VPP 17.04, I'd like to invite you all to try out networking-vpp for VPP 17.04. VPP is a fast userspace forwarder based on the DPDK toolkit, and uses vector packet processing algorithms to minimise the CPU time spent on each packet and maximise throughput. networking-vpp is a ML2 mechanism driver that controls VPP on your control and compute hosts to provide fast L2 forwarding under Neutron.
This version has a few additional features: - resync - this allows you to upgrade the agent while packets continue to flow through VPP, and to update VPP and get it promptly reconfigured, and should mean you can do maintenance operations on your cloud with little to no network service interruption (per NFV requirements) - VXLAN GPE - this is a VXLAN overlay with a LISP-based control plane to provide horizontally scalable networking with L2FIB propagation. You can also continue to use the standard VLAN and flat networking. - L3 support - networking-vpp now includes a L3 plugin and driver code within the agent to use the L3 functionality of VPP to provide Neutron routers. Along with this, there have been the usual bug fixes, code and test improvements. The README [1] explains how you can try out VPP using devstack, which is even simpler than before the devstack plugin will deploy etcd, the mechanism driver and VPP itself and should give you a working system with a minimum of hassle. We will continuing development between now and VPP's 17.07 release in July. There are several features we're planning to work on (you'll find a list in our RFE bugs at [2]), and we welcome anyone who would like to come help us. Everyone is welcome to join our new biweekly IRC meetings, every Monday (including next Monday), 0900 PST = 1600 GMT. [1]https://github.com/openstack/networking-vpp/blob/master/README.rst -- Ian.
