Claude, Short Answer A resource server (called a device in OIC) on IP is represented by a IP address and port number. So, 192.168.1.13:45000 could be a resource server.
Long Answer Let me apologize in advance if you have already done this, but it is best to start by reviewing REST (https://en.wikipedia.org/wiki/Representational_state_transfer) to understand roles and responsibilities and URI (https://en.wikipedia.org/wiki/Uniform_resource_identifier) to understand addressing. Once you are grounded in these two topics, the is easy to say that the classic resource server (called device in OIC speak) is represented by the authority of the URI. NOTE: The Fielding has pointed out the REST description on Wikipedia is not exactly correct, but it is sufficient to developing a basic understanding.

I am graduation student studying Iotivity Hi. I am Claude, graduation student studying Iotivity. I tried to understand the archtiecture of iotivity but I have got in trouble understanding some parts. Please, answer below questions what is server? As i understand the document, all of devices ,smart bulb, door lock and so on, could be server. However, if all of devices are server, there is a problem to register resource. Each resource should have unique URI but it's impossible to do... So i think that server is just one specific computer. However, when client try finding resources(https://www.iotivity.org/documentation/linux/programmers-guide/finding-resource), there is 3 responses. I thought 192.168.1.13 is the server, because the response of this host having 2 resources in payload. However, there are two other responses from 192.168.1.11,192.168.1.12 and these looks like resource server Please, explain me what is the server [http://mail.naver.com/readReceipt/notify/?img=meb9KqFZD6cZM6p0hAnXK6pvaA2rK4J0F4KZpzE%2FMrUmMotXK43SM6uXKEIo%2BrkSKAM5W4d5W4C5bX0q%2BzkR74FTWx%2FspzkrtzwGbX3q740T%2Bz0r1B3l74eZpm%3D%3D.gif] -------------- next part -------------- An HTML attachment was scrubbed...
