Abstract:Network Address Translator (NAT) has brought up many changes and opportunities to the Internet. How do the ubiquitous and pervasive applications coexist with NAT and interoperate with each other? In this article, we discuss the essence of NAT sensitive applications as well as the challenge and response for various NAT traversal solutions. All questions pointed to redesign a new NAT framework with a major change to accommodate NAT problems all at once. We introduce a novel next generation NAT (NATng)
framework, which consists of a Bi-directional NAT (BNAT) and a Domain Name System Application Level Gateway (DNS_ALG) with a Border Network Address Translator Control Protocol (BNATCP)
function to control all BNATs. The above components coordinate and provide bidirectional access capability between intranet and
Internet, so all private hosts can be addressed via Fully Qualified Domain Name (FQDN). Logistically, NATng extends the IPv4 address space from 2<sup>32</sup> to 2<sup>48</sup> or even more. It features high potential to solve the problems for ubiquitous and pervasive applications which may encounter IPv4 address
exhaustion on the current Internet. © 2009 Elsevier Inc. All rights reserved.
