<p class="MsoNormal">My first impression on quickly browsing through your attached document is that it focuses on the service provider abstractions and might be complementary to what we discussed in the above proposal during the summit. That said, it seems
to me that your document makes an assumption that a service chain always manifest as a single multiservice appliance in a VM form-factor and in a single insertion mode. This is one valid use case, however the model should not be limited to this. One can have
a combination of services in different insertion modes and realized on dedicated hardware or in software. Please the aforementioned blueprint/spec for such examples and a flexible model which captures this.<o:p></o:p></p>
