<p class="MsoNormal"><span style="font-size:11.0pt">Hello All,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">We'd like to invite you to try out Networking-vpp 20.05.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">As many of you may already know, VPP is a fast user space forwarder based<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">on the DPDK toolkit. VPP uses vector packet processing algorithms to<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">minimize the CPU time spent on each packet to maximize throughput.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">Networking-vpp is a ML2 mechanism driver that controls VPP on your control<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">and compute hosts to provide fast L2 forwarding under Neutron.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">This latest version of Networking-vpp is updated to work with VPP 20.05.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">In this release, we've made the below changes:<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">- We've added a class that defines network type APIs and implements them.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> The network types supported are VLAN, Flat and GPE. Our intent is to add<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> support for pluggable network types without the need to modify code.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> We'll be continuing our work to enhance this feature in the next release.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">- We've updated the code to be compatible with VPP 20.05 API changes.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">- We've added code to deal with poorly formed security group subnets.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> For instance, 1.2.3.4/0 is completely acceptable in a security group rule.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> Previously, VPP accepted this in its API calls but this is not currently<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> the case. We've fixed this up at the high level to be acceptable to VPP.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">- We've fixed an issue with missing package data required for VPP API<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> message validation.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">- We've dropped VPP 19.04 compatibility code.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">- We've fixed an issue with the security group mechdriver code in which<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> a SG rule is added but not pushed out to VPP until the next rule is added<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> or the security group is changed.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">- We've moved VPP specific constants to a dedicated vpp_constants.py file.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">- Due to a VPP issue, GPE support will be deferred to the 20.05.1 release.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">- We've been doing the usual round of bug fixes, clean-ups and updates - the<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> code will work with VPP 20.05, the OpenStack Stein release & Python 3.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">The README [1] explains how you can try out VPP with Networking-vpp using<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">devstack: the devstack plugin will deploy the mechanism driver with VPP 20.05<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">and should give you a working system with a minimum of hassle.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"><o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt">We will be continuing our development for VPP's 20.05.1 release.<o:p></o:p></span></p>
