<div>Tomaso,</div>

</div>
<div>
<div>Our basic service primative for other protocols to use USLP is the packet primative. It is the same one we have been using for TM, AOS, TC except we also added a Protocol ID field to accommodate upper layer protocols. Do you see a problem with this approach
?</div>
<div>So yes, the I/F is different from AOS, TC, TM but only very slightly different by one parameter.</div>

<p class="MsoNormal"><span style="font-size: 11pt; font-family: Calibri, sans-serif; color: rgb(31, 73, 125);">With this do you mean that higher layer protocol PDUs can be directly encapsulated into USLP, avoiding the use of the Encaps Service? If this is
the case, I guess ( I dont remember right now) that the service primitives exposed to the upper layers (e.g., LTP or BP) will override the primitives currently offered by the Encaps service. On the contrary, if the primitives are different Id say that the
interface between USLP and the higher layer protocols will be different from the case where you have Encaps instead of USLP. Can you develop a bit more on this point?<o:p></o:p></span></p>
