<p class="MsoNormal"><span style="font-size:11.0pt">We'd like to invite you to try out Networking-vpp 20.01.<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 20.01.<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 dropped support for Python 2.7 and updated the code to work with

<p class="MsoNormal"><span style="font-size:11.0pt"> Python 3.6 or later.<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 20.01 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 VPP API versioning support using 2 data files.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> They are API whitelist file and API CRC manifest file. At startup, the vpp-agent<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> will check to see if the API signature is compatible with the installed VPP.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> Also, at runtime, only the whitelisted API calls will be allowed.<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 eventlet that caused problems when binding tap<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt"> interfaces into Linux bridge<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.
