Hi all, These days I have received some feedbacks and questions publicly or privately. Thanks those people for their valuable comments at first.
For better understand of HRA, I want to do some clarification about it here: First, the globally unique HIT within HRA plays the role of host identifier actually, whereas the variable-length HI (the public key) is just used for security purposes such as encryption and authentication. Second, the hierarchical HIT within HRA is in accordance with the characters of an ideal endpoint identifier described in Noel's endpoint namespace draft, such as global uniqueness, Topological Insensitivity, Portability, partially "Local Creatability", Distributed Catalogueabilty, Embedded Organizational Affiliation and Fixed Length. Besides, it's a cryptographic host identifier, and it can be used as a part of secure Internet environment for the purpose of e-commerce healthy development. Take mobile phone as an example, you don't feel inconvenient at the age of no mobile phone, but once you use it, you will find you can not leave it almost. I believe the cryptographic host identifier has some kind of character like mobile phone. Third, the hierarchical global locator namespace (a combination of LD ID and local locator) meets the demand of huge addresses in future Internet at a minimum cost. It has no influence on most of routers except LDBRs, especially from the perspective of forwarding plane. We don't need to suffer the dilemma of IPv6 transition anymore. Fourth, the hierarchical routing mechanism meets the new requirement of routing stability in [draft-irtf-rrg-design-goals-01], as a route churn in one LD will not be flooded in the whole Internet. Lastly, HRA also does some effort from the perspective of deployability. Most of routers except some LDBRs are not required to be replaced or upgraded. Besides, Hierarchical HIT and hierarchical DHT ease the management of the global id/loc mapping system and global uniqueness guarantee mechanism. Any comment is welcomed.
