Hi! Carsten, and everybody: I am so sorry that I disturbed you by post the Independent Submissions here. It is because that I didn't get any notification or decision after the submission. I designed the UTID and IDTP that helps to build a network application with simple design. I would like to find interested persons to discuss this issue. This is the last message I post to this mail list. I appreciated you if you can give me any comments and suggestions in personal email. Especially where and how to find interested persons to discuss this issue. Best regards.

It seems to be interested in some of the use cases of CoAP, and I wonder why it doesn?t discuss its relationship with CoAP, which has been around since before this work started. The draft does mention HTTP, but only in a superficial way as in [IDTP] "is similar to HTTP, Web Service, Java RMI, or CORBA.? It says it maps to TCP, UDP, and HTTP, but doesn?t say how (it does say it uses port 25604 for TCP, which indeed has been allocated in 2011). I was hoping to find some answers in the reference implementation, which has some 7000 lines of Java. There you can find gems such as an XOR ?encryption?. As the drafts didn't really help me find out about their motivation, I was interested to find an ?overview.html? there that has to say this: > 1.4 Why a new protocol? > > There are various coding system and communication protocols widely used in the IOT. The EPC and Web Service are the typical that makes a great contributes to the development of IOT. However, any technology inevitably has some disadvantages. For example, EPC is mainly used in identify products in production process and shipping goods in logistics and is the best coding system in the context. But in the era of IOT, after being produced, a product will go through circulation process, storage process, and consumption process. The same product might need to be recoded in different process by different company using different coding system to provide and share the information of the same product in the different status from different company. For example, no company would like to identify its fixed assets using EPC system, which is originally designed for identify products. The problem is that the communication among these different company and different coding system. The result is the producer is difficult to trace the outgoing process and the consumer is difficult to find the information in the circulation process except the producer. Another example is IP protocol, the key technology in the Internet. But it could not be applied to a network consists of sensors that do not have IP address. > > In generally, we need a coding system and a protocol that are more open, more generalized. This specification provides such an open solution that is independent to any industry or any context. I gave up there, because I cannot make sense of this.
