</span>Isn't that what SFC is? (Service Function Chaining.)<br></blockquote><div>Vikram: Kind-off. SFC chains neutron ports but our requirement is to route all the incoming traffic to a particular VM port before it can take it's normal forwarding logic. In other words neutron router got to steer the traffic to a VM and then to it's normal forwarding behaviour. <br><br>An important use-case could be deploying a separate classifier at the ingress which filters traffic and then route to respective service chains depending upon some logic [May be SF-ID can be stamped in packet as part of NSH header or by some other means.]<br> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
