Keshava, we think that it would be ideal to have two type of use-cases: one which you described below (“dynamic” one) with the usage of IETF-defined header but also one “static” one where the whole chain can be pre-provisioned by the orchestrator via Neutron-API
w/o usage of classifier and header extensions. <o:p></o:p></span></p>

<p><span style="font-family:"Arial","sans-serif"">and I also found that we have a new project about GBP and group-based-policy-service-chaining be located at:</span>

<p style="margin-bottom:12.0pt"><span style="font-family:"Arial","sans-serif"">so I'm confused with solution of the service chaining.</span>
<br>
<br>
<span style="font-family:"Arial","sans-serif"">We are developing the service chaining feature, so we need to know which one is the neutron's choice. Are the blueprints about the service insertion, service chaining and traffic steering list in JunoPlan all Abandoned
? </span><o:p></o:p></p>

<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>
