Jack Lee (?), In OCDoResource, you can supply a port number in the OCDevAddr argument. Network layer will use it, just as in original IoTivity. So the same functionality exists. I still have reservations about the design of counting on port numbers persisting. John

How can forget it? If you right, then iotivity should be redesign. Because, OCDoResource() has port number dependency. If we support just one optional api, we can reduce re-discovery problem. I don't understand why did yoy object to add "OPTIONAL" api although it can provide very useful user exprience. And, old version iotivity could set port number... there is no issue about development ------- Original Message ------- Sender : Thiago Macieira<thiago.macieira at intel.com<mailto:thiago.macieira at intel.com>> Date : 2016-01-22 14:19 (GMT+09:00) Title : Re: [dev] Need API to set static "sid" and "port number".

Forget the port number. If your other side is trying to depend on the port number, please redesign it. You cannot count on the port number being free, so your other side must be able to deal with the port number changing. For that matter, the IP might change after a reboot. Or even without a reboot: IPv6 temporary addresses change about once a day. Since you can't count on the IP being fixed, port numbers don't identify anything. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center [cid:image001.gif at 01D154ED.37CBA3D0] [http://ext.samsung.net/mailcheck/SeenTimeChecker?do=28bccb0e7a1e0d0665c2278d83f0484165a4919a5534baf50cf2282830c3416bfcfabd80c3fe6049141ee34884fd53a813d69ea60670f66ef4bcdeced46ed5ee08cece8541bc14eacf878f9a26ce15a0] -------------- next part -------------- An HTML attachment was scrubbed...
