At that time it was about SelectedDelegation field in Interest tlv format. I just want to know the status of the discussion and arguments in agreement/disagreement. As far as I can say just in the moment, one argument in disagreement could be opening up the surface to mislead interests.</p><p>P.S: For everybody's information, the mentioned filed was introduced because delegation list (a list of forwarding hints) in LINK object may contain more than one hints. Considering calculation overhead, it may be better to have this field filled, so that each router in DFZ does not need to decide which one of hints to choose for forwarding. Since choosing which hint as selected one, needs information about topology, traffic links and etc, an end application seems not to able to decide on this matter.</p><p>Thanks,<br>Sabet</p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman",serif'><o:p> </o:p></span></p></div></body></html>
