1. Executive Summary
The two most commonly cited issues motivating the introduction of
IPng are address depletion and routing table growth in IPv4. Further
motivation is the fact that the Internet is witnessing an increasing
diversity in the protocols and services found in the network. When
evaluating alternatives for IPng, we should consider how well each
alternative addresses the problems arising from this diversity. In
this document, we identify several features that affect a protocol's
ability to operate in a multiprotocol environment and propose the
incorporation of these features into IPng.
Our thesis, succinctly stated, is: The next generation Internet
Protocol should have features that support its use with a variety of
The Internet is not a single protocol network . While TCP/IP
remains the primary protocol suite, other protocols (e.g., IPX,
AppleTalk, OSI) exist either natively or encapsulated as data within
IP. As new protocols continue to be developed, we are likely to find
that a significant portion of the traffic in future networks is not
from single-protocol communications. It is important to recognize
that multiprotocol networking is not just a transition issue. For
instance, we will continue to see tunneling used to carry IPX traffic
over the Internet between two Novell networks. Furthermore, the
introduction of IPng is not going to result in a near term
elimination of IPv4. Even when IPng becomes the primary protocol
used in the Internet, there will still be IPv4 systems in use. We
should consider such multiprotocol uses of the network as we design
future protocols that can efficiently handle mixed protocol traffic.
We have identif...
