Hello All, We'd like to invite you to try out Networking-vpp 19.08.1. As many of you may already know, VPP is a fast user space forwarder based on the DPDK toolkit. VPP uses vector packet processing algorithms to minimize the CPU time spent on each packet to maximize 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 latest version of Networking-vpp is updated to work with VPP 19.08.1 In this release, we've worked on the below updates: - We've added ERSPAN support for Tap-as-a-Service (TaaS). Since ERSPAN provides remote port mirroring, you can now mirror your OpenStack traffic to a destination outside of OpenStack or to a remote OpenStack VM. This is a customized version of OpenStack TaaS. We will be working with the community to push our custom TaaS extensions upstream. In the meantime, you can access our modified TaaS code here[2]. For further info on installation and usage, you can read the TaaS-README[3]. - We've updated the code to be compatible with VPP 19.08 & 19.08.1 API changes. - We've updated the unit test framework to support python3.5 onwards. - We've added security-group support for Trunk subports. We've added support for neutron trunk_details extension. - We've fixed some bugs in our Trunk and L3 plugins that caused a race condition during port binding. - We've migrated our repo from OpenStack to OpenDev. - A recent change in nova caused live migration to fail for instances with NUMA characteristics. We've found that this is a limitation in nova and not VPP/Networking-vpp. It is still possible to use live migration with VPP/Networking-vpp. Please refer to the README[1] for further details. - We've been doing the usual round of bug fixes and updates. The code will work with VPP 19.08.1 and has been updated to keep up with Neutron Rocky and Stein. The README [1] explains how you can try out VPP with Networking-vpp using Devstack: the Devstack plugin will deploy the mechanism driver and VPP and should give you a working system with a minimum of hassle. We will be continuing our development for VPP's 20.01 release. We welcome anyone who would like to come help us. -- Naveen, Ian & Jerome [1] https://opendev.org/x/networking-vpp/src/branch/master/README.rst [2] https://github.com/jbeuque/tap-as-a-service [3] https://opendev.org/x/networking-vpp/src/branch/master/README_taas.txt
