Abstract
The information transfer protocol that supports the modern Internet with its hundreds of thousands of petabytes per month to billions of Internet users across the world was designed in 1981, and it lacks the capacity to properly ensure the security and stability of the Internet today. Features such as the prevention of network attacks, a large address space for the increasing number of devices, verification of the source of an Internet request, and so on are all absent from the current architecture. This paper seeks to review, summarize, and compare six proposals submitted to address the issues IP faces: the Accountable Internet Protocol, the Expressive Internet Architecture, MobilityFirst, Passport, StopIt, and the Traffic Validation Architecture. Finally, the paper details a protocol design that not only is feasible to adopt with the present infrastructure/computing power but also addresses some of the pressing issues of IP, with particular focus on the address space, mitigation of network attacks, and source verification.
Highlights
The information transfer protocol that supports the modern Internet with its hundreds of thousands of petabytes per month to billions of Internet users across the world was designed in 1981 for limited use by the ARPANET connecting American universities (RFC 791 - Internet Protocol, 1981)
The content of this paper aims to describe the various proposals to improve Internet Protocol (IP), which can be sorted into a few major categories based on the level of change to the overall IP architecture
IP addresses are structured hierarchically; every autonomous system (AS) is assigned a block of IP addresses routed to them according to their assigned network bits of the IP addresses, which is forwarded to the end hosts within their network with the host bits of the IP address (RFC 1930 Guidelines for Creation, Selection, and Registration of an Autonomous System (AS), 1996)
Summary
The information transfer protocol that supports the modern Internet with its hundreds of thousands of petabytes per month to billions of Internet users across the world was designed in 1981 for limited use by the ARPANET connecting American universities (RFC 791 - Internet Protocol, 1981). The number of Internet Protocol (IP) addresses available for private use has been exhausted and can only be acquired through a change of ownership. Numerous proposals have been submitted to address these issues to limited adoption by the Internet as a whole. The content of this paper aims to describe the various proposals to improve IP, which can be sorted into a few major categories based on the level of change to the overall IP architecture. The paper proposes an architecture resolving some of the issues of IP after the comparison of the strengths and weaknesses of existing approaches. The architecture, detailed, combines the existing proposals of the Accountable Internet Protocol and Traffic Validation Architecture and addresses the concerns and changes to IP of each, unifying them into a single proposal. The paper describes the estimated performance of the architecture, changes to the existing IP infrastructure, examples of usage, cases of improvements over IP, and plans for the deployment of the architecture
