ICMP translation within REBEKAH-IP

The third generation (3G) cellular networks are starting to be deployed around the world. These networks are predicted to bring a vast number of IP enabled cellular terminals to the Internet. The limited address space of the current version of IP in the Internet, IPv4, has made the cellular industry decide to use IPv6 for these terminals. However, their success will largely depend on the availability of successful services and, initially, these will largely constitute existing services. These services all reside in the current IPv4 address space, which makes them inaccessible to the 3G terminals that reside in the IPv6 address space. There have been many proposals for translating between the two address spaces. One of these proposals, REBEKAH-IP, is promising in that it provides excellent scalability and also does not limit the services that can be provided. The paper presents an extension of REBEKAH-IP to support important error feedback, control and debugging functions that are generated by end-hosts through the use of ICMP (Internet control message protocol).
