Re: [External] Request for information - Challenges in routing related to semantic addressing

Joel

You have to start somewhere. Semantic routing is a staring point for a concept that clearly we need to research and gradually understand. If at the end of the process a better name emerges, no one will be precious about the word semantic. However for now we need to understand the mapping of the requirement to the need and then to determine the optimum name. For now, the term semantic routing seems to describe the direction even if it does not fully describe the destination.

Although the initial literature review highlighted some common objectives across proposals and implementations, I struggled to find anything that defined "semantic routing" and goals that we could use/reference. I likely missed prior research that provides a useful definition. If not, then I agree that having the IRTF research community document a description for "semantic routing" and common goals, would be beneficial.
