| Research Abstract |
The IPv4++ is an IPv4 compatible protocol. Unlike IPv4, it provides unlimited number of addresses by a multiple virtual address space technique. The IPv4++ network is a collection of IPv4 network called realm and realms are connected each other via DAT(Dynamic Address Translator). IPv4++ assumes that the realms form a tree structure and each realm has a unique local IPv4 address within its upper realm. Each realm has a unique IPv4++ address formed by concatenating its local IPv4 addresses from the leaf to the root. In a realm, DAT allocates a virtual IPv4 address for an external destination host on-demand. Because of the access locality, only a small number of IP addresses are required to access whole the lPv4++ address space. Thus, DAT provides access transparency between any realms.
Our activities in the fiscal year of 2006 and 2007 are follows ;
1. We found that the concept of a tree structured realm make it easy to explain the IPv4++ network architecture. It is named Free Scale Network Architecture because of the unlimited address space expansion capability provided by DAT.
2. For the mission-critical use, we found that a backup routing function is indispensable. It is provided by inter-DAT protocol named RGP(Realm Gateway Protocol). RGP adopts TPV(Temporal Path Vector) algorithm to accelerate the route convergence. RGP is upward compatible with the conventional BGP(Border Gateway Protocol).
3. We came to the conclusion that POC(Proof of Concept) is indispensable for the marketing prior to standardize the IPv4++ protocol. Thus, we focused on developing POC rather than writing its protocol documents.
4. Although we focused on implementing POC within these fiscal years, we have not completed it yet. We believe that it will take a couple of months to complete it.
