<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">We have a long standing PR from Manohar Castelino in the runtime repo, [1], which removes the bridge networking model.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">In the bridge networking model, a bridge is created in the network namespace, and the veth is connected to the VM’s tap. This is the least performant and a bit more complex than necessary. We recommend end-users
utilize tc-filter (default) or macvtap.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">Zhang Wei brought up the concern of whether end-users could be using bridge today. I hope they aren’t, but am now considering whether this should be a 2.0 candidate, and whether this should be considered
a breaking change.<u></u><u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt"><u></u> <u></u></span></p>
<p class="MsoNormal"><span style="font-size:11pt">Feedback? I’d like input from other AC members here so we can make forward progress on this PR, and/or on 2.0 planning.<u></u><u></u></span></p>
