<p class="MsoNormal"><span style="color:#1F497D">Thanks for your suggestion. Yes, we can add Application ID to the parameter of the flow classifier/filter. The next updated version will reflect this. Actually in its existing design, the parameter field of the
flow classifier can be extended in the future to include more flow descriptors for more granular differentiation of flows.

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Per earlier suggestion from Isaku etc., we can also add a “context” field to the service chain API. The context field will include information such as “the encapsulation mechanism” used by the service functions
in the chain, which can be NSH, VLAN, none etc. so that the Service Function Forwarder (the vSwcitch) knows whether it should act as a SFC proxy or not and if acting as a Proxy, what is the chain correlation mechanism between the Service Function Forwarder
and the Service Function. <o:p></o:p></span></p>

<p class="MsoPlainText">In IETF SFC draft-penno-sfc-appid-00 proposed a notion of ApplicationId, a generic attribute that can be included in NSH metadata. This reflects also on ODL SFC wich has introduced the Application Id as a parameter that can be used
by the Classifier to steer traffic into a chain.<span lang="FR"><o:p></o:p></span></p>
