RSIP: Address Sharing with End-to-End Security
Michael Borella, 3Com; Gabriel Montenegro, Sun Microsystems
Abstract
Realm Specific IP (RSIP) is a new architecture under consideration in the Internet Engineering Task Force (IETF) that can potentially alleviate some of the problems associated with partitioning of the Internet address space due to, for example, the shortage of IPv4 addresses. It is being positioned as a replacement for Network Address Translation (NAT), because, among other things, it can support end-to-end security via IPsec, which NAT cannot. This paper introduces the motivation behind RSIP, the RSIP architecture, and provides a basic overview of the RSIP protocol.
