Hi Jaime,

using IP address and port for an endpoint (client) name would not be a good idea.
In general, it was not a good idea to have this parameter defined in the first place. It might actually be better to remove it altogether.

Ciao
Hannes

Hi,

Note that endpoint can refer to both source and destination, being and IP:port in its simplest form:
https://tools.ietf.org/html/rfc7252#page-6

The fact that LWM2M swaps those role names might actually add to the confusion, probably OMA LWM2M should be the one changing the terminology as the device is mostly a “server” hosting resources and only is a “client” during bootstrapping and registration. We could have used terms like “servient” instead but it might be too late for that.

Ciao!

Hi all,

I noticed that the term “endpoint name” is used in the IETF RD draft while the OMA LwM2M spec uses the term “endpoint client name”. Endpoint is a confusing term since it is used differently in the CoAP spec than in the Web environment.

For this reason I believe it would be better to use the term “endpoint client name” also in the RD draft. This would improve alignment between the two specs.

Ciao
Hannes
