<p class="MsoNormal">Service chaining isn't in the plan for Kilo [1], but I expect it to be something we talk about in Vancouver for the Lxxx release. The NFV/Telco group has been talking about this as well. I'm hopeful we can combine efforts and come up with
a coherent service chaining solution that solves a handful of useful use cases during Lxxx.<br>
<br>
Thanks,<br>
