This memo presents two recommendations to the Internet community concerning measures to improve and preserve Internet performance. It presents a strong recommendation for testing, standardization, and widespread deployment of active queue management in routers, to improve the performance of today’s Internet. It also urges a concerted effort of research,(More)
The architecture of the Internet is based on a number of principles, including the self-describing datagram packet, the end to end arguments, diversity in technology and global addressing. As the Internet has moved from a research curiosity to a recognized component of mainstream society, new requirements have emerged that suggest new design principles, and(More)
We propose a new objective for network research: to build a fundamentally different sort of network that can assemble itself given high level instructions, reassemble itself as requirements change, automatically discover when something goes wrong, and automatically fix a detected problem or explain why it cannot do so.We further argue that to achieve this(More)
This paper proposes GIA, a scalable architecture for global IP-anycast. Existing designs for providing IP-anycast must either globally distribute routes to individual anycast groups, or confine each anycast group to a pre-configured topological region. The first approach does not scale because of excessive growth in the routing tables, whereas the second(More)
Charter The goal of this project was to consider the following question: if we could now design the Internet from scratch, knowing what we know today, how would we make the basic design decisions? The phrase " design from scratch " implies that we deliberately set aside issues of migration—how we would get from where we are today to a new design tomorrow.(More)
Since 2004, the DETER Cybersecurity Testbed Project has worked to create the necessary infrastructure — facilities, tools, and processes-to provide a national resource for experimentation in cyber security. The next generation of DETER envisions several conceptual advances in testbed design and experimental research methodology, targeting improved(More)
Connectivity is central to pervasive computing environments. We seek to catalyze a world of rich and diverse connectivity through technologies that drastically simplify the task of providing, choosing, and using wireless network services; creating a new and more competitive environment for these capabilities. A critical requirement is that users actually(More)
Routing on the Internet today is as much about money as it is traffic. The business relationships of an ISP largely dictate its routing policy and drive the work of its engineers. In today's routing mechanism, this leads to a number of well-known pathologies. This structure is further challenged by the emergence of user-directed routing.This paper explores(More)
